Ethereum wallet/Mist unable to connect to test network

I installed geth 1.8.3 on my x64 win10 laptop. The first time I booted up Ethereum Wallet/Mist x32/64, the screen stayed on "checking for node update" for about 3 hrs and then turned to "Ethereum node up-to-date" and keep downloading blockchain from the main network. I tried to kill the program and I found even though Ethereum Wallet/Mist was closed, geth was still running in the background.
When I killed the program when it was at "checking for node update" and reopen the program, it successfully went through the previous stages and went to the "downloading node from main network" screen. It didn't pop up a window to allow me choose which network I want to connect to before it started downloading blockchain from the main network. After I hit "launch application", network choices are in grey and I couldn't select any 1 of the 4(I wish to connect to the test network).
Does anyone have any idea on how to solve it? Thanks!

I'm new to metamask and just today when I logged in it was stucked on the "Connecting" part. As a work around, you just have to change it to the test network. then the connecting will stop. then change back to the main ethereum network. then login. this worked for me. hope this helps :)

How can I have Ethereum Mist wallet connected with the Main network and second for testing purposes connected to a private chain?

I want to test smart contracts on the test private network but at the same time, I have real eth in my mist wallet. So, I am wondering how can I have both at the same time? Please let me know! Cheers

Is Truffle the best framework for deploying contracts?

If you're building a relative complex dApp or Game , would remix IDE be insufficient? Is remix IDE mainly for simpler contracts?
And sorry for the newbie question, how exactly do you send ether to deploy the contract on Truffle, does Truffle use the metamask plugin?
Still new to everything, thanks!

SIA press release: Quant Network and SIA successfully tested blockchain interoperability

The breakthrough was achieved by integrating Quant Network’s Overledger technology into the SIAchain private blockchain infrastructure to enable cross-platform applications and services in Europe and globally
London and Milan, 24 June 2020 – Quant Network, a leading pioneer in enterprise blockchain technology, and SIA, European hi-tech company leader in the fields of payment services and infrastructures and a subsidiary of CDP Equity, have successfully tested cross blockchain interoperability between multiple Distributed Ledger Technology protocols. The breakthrough was achieved by integrating Quant Network’s Overledger technology (the world’s only DLT operating system that allows interoperability) into the SIAchain private blockchain infrastructure leveraging on 580 European network nodes within SIAnet (the fiber optic network with high-speed and low-latency stretching over 208,000 kilometres). This integration provides the ability to bridge permissioned blockchain instances between SIAchain and other external networks – which could not be previously connected - in order to have cross-platform applications and services covering for example notarisation, payments and KYC.
The development of the solution began in mid-2019 and a full program of testing has been executed on SIAchain, R3 Corda and private Ethereum platforms. Quant Network and SIA will now work together to go to the market developing and implementing further innovative use cases and applications addressing blockchain interoperability challenges.
This important milestone is the result of a partnership launched between Quant Network and SIA that allows mostly banks and financial institutions - through the SIAchain infrastructure - to adopt cross-platform and interoperable blockchain solutions and to embrace new business models, improve operational efficiencies and deliver innovation to banking customers.
“The partnership between Quant Network and SIA has been extremely positive and productive from the very start,” said Gilbert Verdian, CEO, Quant Network, “and both companies are confident that this development will play an integral part in building the financial infrastructure of the future globally.”
“The achievement of a fully interoperable blockchain network, through our collaboration with Quant Network, is another key-element in our path of bringing innovation and state-of-the-art technologies for supporting banks, financial institutions, corporates and public administration bodies to extend their capabilities in integrating different DLT business applications” said Daniele Savarè, Innovation & Business Solutions Director SIA.

Ethereum on ARM. New Eth2.0 Raspberry pi 4 image for automatically joining Prylabs Onyx Eth2.0 testnet. Step-by-step guide for installing and activating a validator.

TL;DR: Flash your Raspberry Pi 4, plug in an ethernet cable, connect the SSD disk and power up the device to join the Eth2.0 Onyx testnet.
The image takes care of all the necessary steps to join the Eth2.0 Onyx testnet [1], from setting up the environment and formatting the SSD disk to installing and running the Ethereum Eth1.0 and Eth2.0 clients as well as starting the blockchains synchronization (for both Geth Eth1.0 Goerli [2] and Prysm [3] Eth2.0 Beacon Chain).
You will only need to create a validator account, send the deposit of 32 Goerli ETH to the Onyx contract and start the validator systemd service.
MAIN FEATURES
SOFTWARE INCLUDED

INSTALLATION GUIDE AND USAGE

RECOMMENDED HARDWARE AND SETUP
STORAGE
You will need and SSD to run the Ethereum clients (without an SSD drive there’s absolutely no chance of syncing the Ethereum blockchain). There are 2 options:
In both cases, avoid getting low quality SSD disks as it is a key component of you node and it can drastically affect the performance (and sync times). Keep in mind that you need to plug the disk to an USB 3.0 port (in blue).
IMAGE DOWNLOAD AND INSTALLATION
1.- Download the image:
http://www.ethraspbian.com/downloads/ubuntu-20.04-preinstalled-server-arm64+raspi-eth2-onyx.img.zip
SHA256 13bc7ac4de6e18093b99213511791b2a24b659727b22a8a8d44f583e73a507cc
2.- Flash the image
Insert the microSD in your Desktop / Laptop and download the file:
Note: If you are not comfortable with command line or if you are running Windows, you can use Etcher [8]
Open a terminal and check your MicroSD device name running:
sudo fdisk -l 
You should see a device named mmcblk0 or sdd. Unzip and flash the image:
unzip ubuntu-20.04-preinstalled-server-arm64+raspi-eth2-onyx.img.zip sudo dd bs=1M if=ubuntu-20.04-preinstalled-server-arm64+raspi.img of=/dev/mmcblk0 conv=fdatasync status=progress 
3.- Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port).
4.- Power on the device
The Ubuntu OS will boot up in less than one minute but you will need to wait approximately 7 minutes in order to allow the script to perform the necessary tasks to join the Onyx testnet (it will reboot again)
5.- Log in
You can log in through SSH or using the console (if you have a monitor and keyboard attached)
User: ethereum Password: ethereum 
You will be prompted to change the password on first login, so you will need to log in twice.
6.- Forward 30303 and 13000 ports in your router (both UDP and TCP). If you don’t know how to do this, google “port forwarding” followed by your router model.
7.- Getting console output
You can see what’s happening in the background by typing:
sudo tail -f /valog/syslog 
7.- Grafana Dashboards
There are 2 Grafana dashboards to monitor the node (see section “Grafana Dashboards below”.
See [9]

The Onyx Eth2.0 testnet

Onyx is an Eth2.0 testnet created by Prylabs according to the latest official specification for Eth2.0, the v0.12.1 [10] release (which is aimed to be the final).
In order to run an Onyx Eth 2.0 node you will need 3 components:
The image takes care of the Eth1.0 Geth and Eth2.0 Beacon Chain configurations and syncs. So, once flashed (and after a first reboot), Geth (Eth1.0 client) starts syncing the Goerli testnet and the Beacon Chain (Eth2.0 client) gets activated through the Prysm client, both as systemd services.
When the Goerli testnet sync is completed, the Beacon Chain starts syncing. Both chains are necessary as the validator needs to communicate with them (as explained below).
Activating the validator
Once Goerli and the Beacon chain are in sync you have just one task left, configure the Validator for enabling the staking process.
The image provides the Prysm validator client for running the staking process. With this validator, you will create an account with 2 keys (public and private) and get an HEX string that needs to be sent to the Eth 1.0 blockchain as data through a 32 ETH transaction.
The Beacon Chain (which is connected to the Eth1 chain) will detect this deposit (which includes the validator public key) and the Validator will be activated.
So, let’s get started. Geth Goerli testnet and the Beacon Chain are already syncing in the background. Goerli will sync in about 1 hour and the Beacon Chain in about 2 hours (so this will take 3 hours overall).
The easiest way to enable a Prysm validator is to use the Prylabs web portal to get Goerli ETH (testnet ETH) and follow their instructions:
https://prylabs.net/participate
Let’s break this down:
Step 1) Get Prysm
Nothing to do here. Prysm is already installed.
Step 2) Get GöETH — Test ETH
We need 32 ETH to stake (it is fake ETH as this is a tesnet). Prylabs created a faucet with a great UI so you can easily get 32.5 Goerli ETH.
You will need a web3 provider to use the faucet. Install Metamask browser extension (if you don’t have it running yet). Create an account and set the network to “Goerli test network” (on the top of the Metamask screen). Now, click once in “Metamask” and then click “Need GoETH?” button. Confirm the transaction.
Once funded, you will see something like this:
You are 0x0b2eFdbFB8EcaF7F4eCF6853cbd5eaD86510d63C and you have 32.5 GöETH. 
Step 3). Generate a validator public / private key
Go to your Raspberry Pi console and run the following command (make sure you are logged in with your ethereum user):
validator accounts create 
Press return to confirm the default path
Enter a password twice (you will need it later to run the validator so write it down and be careful). Once finished, your account will be created (under the /home/ethereum/.eth2validators directory) containing, among other info, your validator keys. Additionally you will get the deposit data as follows (this is an example):
========================Deposit Data======================= 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 =================================================================== ***Enter the above deposit data into step 3 on https://prylabs.net/participate*** 
Copy this data (just the hexadecimal part, from 0x to the last number), go back to step 3 of Prylabs website and paste it into the field “Your validator deposit data”.
Step 4) Start your beacon chain & validator clients
Beacon chain is already running in the background so let’s configure the validator. Just edit the /etc/ethereum/prysm-validator.conf file and replace “changeme” string with your password (you can use nano or vim editors). Now run:
sudo systemctl enable prysm-validator && sudo systemctl start prysm-validator 
Check if everything went right by running:
sudo systemctl status prysm-validator 
Step 5) Send a validator deposit
We are almost there. Just click the “Make deposit” button and confirm the transaction.
Done!
Now you need to wait for the validator to get activated. In time, the beacon chain will detect the 32 ETH deposit (which contains the validator public key) and the system will put your validator in queue. These are the validator status that you will see during the activation process:

Grafana Dashboards

We configured 2 Grafana Dashboards to let users monitor both Eth1.0 and Eth2.0 progress. To access the dashboards just open your browser and type your Raspberry IP followed by the 3000 port:
http://replace_with_your_IP:3000 user: admin passwd: ethereum 
There are 3 dashboards available:
Lot of info here. You can see for example if Geth is in sync by checking (in the Blockchain section) if Headers, Receipts and Blocks are aligned or easily find the validator status.

Whats's next

We are planning a new release for a multi testnet Eth2.0 network including Prysm, Teku and Lighthouse client (and hopefully Nimbus).

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

The Unofficial Cardano FAQ - V3

(if you would like to add information or see mistakes, just comment below and I will credit you)
What is Cardano? Cardano is an open source and permissionless "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm known as Ouroboros to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules (smart contracts) when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another development team - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work - which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but Bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. This was a major step forward for the E-cash concept that people have been working on for the 20 years prior.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins and platforms to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms. Meaning it is still not truly interoperable. Most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling. Also missing is a built-in method to pay for upgrades and voting mechanics for decision making.
Gen 3 blockchains are a complete package designed to replace the current financial infrastructure of the world. Cardano is using Proof of Stake to ensure security and decentralisation(Shelley). Scaling through parallel computation (Hydra in Basho), Sidechains to allow the platform to interact with other platforms (Basho), and also include mechanisms for voting for project funding, changes to the protocol and improvement proposals (Voltaire). Finally smart contracts platform for new and established projects that are developer friendly (Goguen).
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain.
www.Cardano.org www.emurgo.io https://cardanofoundation.org/en/
What is the difference between Proof of Work and Proof of stake? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half validators agree, then the ledger is updated and the transaction is now secured. Proof-of-Work (PoW) happens when a miner is elected to solve an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice. At the moment there are 8 main mining operations for bitcoin, and 4 of them make up more that 51% of the mining power.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool.
What is a stake-pool and how does it work? Cardano.org FAQ on the issue goes into much more detail
A stake pool is where the computing power of the network takes place. During ITN there was 1200 registered stake pools while 300 were creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
Can I Stake my ADA right now? The staking testnet has closed, If you participated in the Incentivised Test Net and earned rewards, instructions to check the balance are here.
However if you have just purchased some or it was held on an exchange, then you will need to wait until the Shelley mainnet launch happening at the end of July 2020.
Where do I stake my ADA? Daedalus Flight wallet, and Yoroi Wallet (as a chrome extension) are the current best options. Adalite and several other third-party wallets also exist. Coinbase will also allow staking as a custodial service, and many exchanges may offer “staking as a service” so you can leave your coins on the exchange and still earn rewards if you enjoy trading. I do not recommend leaving coins on an exchange unless you are actively trading.
What are the staking rewards now and what can I expect on a return in the future? The Incentivised Test Net (ITN) Delivered 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic.
Check https://staking.cardano.org/en/calculato for a clearer picture.
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 50 pools with a 1,00ADA pledge each will be overall less profitable than 1-2 pool with the max ADA pledge (unknown but likely around 300k). Even if the 50 pools have the same over stake delegated by other users and have a better chance of being selected to close a block, the 50 pools may receive lower rewards.. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atala, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an early adopter of cryptocurrencies, American entrepreneur and cryptocurrency specialist. Charles Co-founded Ethereum with Vitalik Buterin and 5-8 others, However he only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? Cardano and coinbase have recently connected in a big way. With IOHK turning over all their ADA to the custodial services of Coinbase. This means that Cardano and Coinbase have been working together for some time and there is a strong partnership forming. Staking and cold storage will be available and trading on Coinbase will most likely become available after the release of Shelley (although no official word yet)
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki
https://cardanowiki.info/wiki/Home
What is Atala and why do I care?*
Atala is a suite of services being developed on top of the cardano blockchain by IOHK that focusses on credential certification, for things like education, work history and degrees (Atala Prism). Product counterfeiting protection through registering products on a blockchain and create taper-proof provenance. This does not only apply to Gucci handbags, but also medication, art, and anything that can be counterfeited (Atala Scan). As well as supply chain tracking to see issues and inefficiencies with greater transparency(Atala Trace).
Im new, how much is a good investment?
Cardano is still a speculative market and although there is amazing potential here, it is still only potential. When investing in any High risk market like Crypto, only every invest what you are willing to lose. Cardano may be testing the 10c barrier now. But in March it dumped to 1.7c. And if you suddenly need your money back during the dump then you are out of luck. Do your research before you FOMO in. Start with a small amount and send it between wallets and exchanges to understand how the system works. Store your private keys offline (or online cloud service but encrypted) with a method that is unlikely to be damaged AND have multiple copies. So in the case of a house fire or a blow to the head, or the cloud service being shutdown/destroyed, you do not lose your money.

Ethereum on ARM. Raspberry Pi 4 images release based on Ubuntu 20.04 64 bit. Turn your Raspberry Pi 4 into an Eth 1.0 or Eth 2.0 node just by flashing the MicroSD card. Memory issues solved and new monitoring dashboards. Installation guide.

TL;DR: Flash your Raspberry Pi 4, plug in an ethernet cable, connect the SSD disk and power up the device to turn the Raspberry Pi 4 into a full Ethereum 1.0 node or an Ethereum 2.0 node (beacon chain / validator)
Some background first. As you know, we’ve been running into some memory issues [1] with the Raspberry Pi 4 image as Raspbian OS is still on 32bits [2] (at least the userland). While we prefer to stick with the official OS we came to the conclusion that, in order to solve these issues, we need to migrate to a native 64 bits OS
Besides, Eth 2.0 clients don’t support 32 bits binaries so using Raspbian would exclude the Raspberry Pi 4 from running an Eth 2.0 node (and the possibility of staking).
So, after several tests we are now releasing 2 different images based on Ubuntu 20.04 64bit [3]: Eth 1.0 and Eth 2.0 editions.
Basically, both are the same image and include the same features of the Raspbian based images. But they are setup for running Eth 1.0 or Eth 2.0 software by default
Images take care of all the necessary steps, from setting up the environment and formatting the SSD disk to installing and running the Ethereum software as well as starting the blockchain synchronization.

Main features

Software included

Both images include the same packages, the only difference between them is that Eth 1.0 runs Geth by default and Eth 2.0 runs Prysm beacon chain by default.
Ethereum 1.0 clients
Ethereum 2.0 clients
Ethereum framework

INSTALLATION GUIDE AND USAGE

Recommended hardware and setup

Storage

You will need and SSD to run the Ethereum clients (without an SSD drive there’s absolutely no chance of syncing the Ethereum blockchain). There are 2 options:
In both cases, avoid getting low quality SSD disks as it is a key component of you node and it can drastically affect the performance (and sync times)
Keep in mind that you need to plug the disk to an USB 3.0 port (blue)

Image download & installation

Note: If you are not comfortable with command line or if you are running Windows, you can use Etcher (https://etcher.io)
Open a terminal and check your MicroSD device name running:
sudo fdisk -l 
You should see a device named mmcblk0 or sdd. Unzip and flash the image:
unzip ubuntu-20.04-preinstalled-server-arm64+raspi-eth1.img.zip sudo dd bs=1M if=ubuntu-20.04-preinstalled-server-arm64+raspi-eth1.img of=/dev/mmcblk0 && sync 
3.- Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port).
4.- Power on the device
The Ubuntu OS will boot up in less than one minute but you will need to wait approximately 10 minutes in order to allow the script to perform the necessary tasks to turn the device into an Ethereum node and reboot the Raspberry.
Depending on the image, you will be running:
5.- Log in
You can log in through SSH or using the console (if you have a monitor and keyboard attached)
User: ethereum Password: ethereum 
You will be prompted to change the password on first login, so you will need to login twice.
6.- Open 30303 port for Geth and 13000 if you are running Prysm beacon chain. If you don’t know how to do this, google “port forwarding” followed by your router model.
7.- Getting console output
You can see what’s happening in the background by typing:
sudo tail -f /valog/syslog 
Congratulations. You are now running a full Ethereum node on your Raspberry Pi 4.

Syncing the Blockchain

Now you need to wait for the blockchain to be synced. In the case of Eth 1.0 This will take a few days depending on several factors but you can expect up to about 5-7 days.
If you are running the Eth 2.0 Topaz tesnet you can expect 1-2 days of Beacon chain synchronization time. Remember that you will need to setup the validator later in order to start the staking process (see “How to run the Eth 2.0 validator” section below).

Monitoring dashboards

For this first release, we included 3 monitoring dashboards based on Prometheus [5] / Grafana [6] in order to monitor the node and clients’ data (Geth and Besu). You can access through your web browser:
URL: http://your_raspberrypi_IP:3000 User: admin Password: ethereum 

Switching clients

All clients run as a systemd service. This is important because in case of some problem arises the system will respawn the process automatically.
Geth and Prysm beacon chain run by default (depending on what you are synchronizing, Eth 1.0 or Eth 2.0) so, if you want to switch to other clients (from Geth to Nethermind, for instance), you need to stop and disable Geth first, and enable and start the other client:
sudo systemctl stop geth && sudo systemctl disable geth 
Commands to enable and start each Eth 1.0 client:
sudo systemctl enable besu && sudo systemctl start besu sudo systemctl enable nethermind && sudo systemctl start nethermind sudo systemctl enable parity && sudo systemctl start parity 
Eth 2.0:
sudo systemctl stop prysm-beacon && sudo systemctl disable prysm-beacon sudo systemctl start lighthouse && sudo systemctl enable lighthouse 

Changing parameters

Clients’ config files are located in the /etc/ethereum/ directory. You can edit these files and restart the systemd service in order for the changes to take effect. The only exception is Nethermind which, additionally, has a mainnet config file located here:
/etc/nethermind/configs/mainnet.cfg 
Blockchain clients’ data is stored on the ethereum home account as follows (note the dot before the directory name):
Eth 1.0
/home/ethereum/.geth /home/ethereum/.parity /home/ethereum/.besu /home/ethereum/.nethermind 
Eth2.0
/home/ethereum/.eth2 /home/ethereum/.eth2validators /home/ethereum/.lighthouse Hyperledger Besu and Nethermind 

Nethermind and Hyperledger Besu

These 2 great Eth 1.0 clients have become a great alternative to Geth and Parity. The more diversity in the network, the better, so you may give them a try and contribute to the network health.
Both need further testing so feel free to play with them and report back your feedback.

How to run the Eth 2.0 validator (staking)

Once the Topaz testnet beacon chain is synchronized you can run a validator in the same device. You will need to follow the steps described here:
https://prylabs.net/participate
The first time, you need to create manually an account by running the “validator” binary and setup a password. Once you completed this step you can add the password to /etc/ethereum/prysm-validator.conf and start the validator as a systemd service

Feeback appreciated

We put a lot of work trying to setup the Raspberry Pi 4 as a full Ethereum node as we know the massive user base of this device may have a very positive impact in the network.
Please, take into account that this is the first image based on Ubuntu 20.04 so there may be some bugs. If so, open an issue on Github or reach us on twitter (https://twitter.com/EthereumOnARM).

The future of dApp development. The end of blockchain tribalism

The future of dApp development. The end of blockchain tribalism
If you are a dApp developer this is a must read!
As all the blockchains have their advantages and disadvantages there is no blockchain which will rule them all. Each blockchain will get congested as soon there are too much “mass adoption” dApps on it, which actually getting used. One blockchain is more decentralized, another more performant.
The solution are decentralized services which are validated and 100% ONchain. A platform layer where dApps can choose what they need, without important trade-offs for their applications. And everybody who want to offer a service, can offer them as a Service Provider. The DAPP services are the new (Amazon) Web Services but decentralized, affordable and for blockchains. Today the DAPP Network counts already 35 DSP’s (DAPP Service Providers) offering 120 services (packages) and counting…
The internet of Blockchains - enabled by the universal middleware of the DAPP Network
The DAPP Network is the first solution which offers this kind of decentralized services. And with the Chintai.io DAPP Resource Exchange where developers can rent DAPP tokens for an affordable price for 30 days, they can pay monthly with a ‘pay-as-you-go” model for their resources and scale their dApps step by step. And it doesn’t make a difference if it’s a new developed dApp or if somebody want to use services for an already existing dApp. If the dApp already exists on a specific blockchain, it can stay on that blockchain and nonetheless use services or scale without tradeoffs. No need any more to change to another blockchain thanks to LiquidLink.
What do you think will happen to the crypto space when companies and big enterprises start to realize that they are independent of any specific blockchain and that they can scale/tokenize their dApps 100% ONchain to an affordable price to mass adoption without any tradeoffs?
Get/Buy DAPP tokens on Bancor.network or Newdex.io before big exchanges start to list DAPP. Today DAPP is worth 0.015$ per token. The concept is in my opinion a breakthrough! Just think about Chainlink is today around 5$ per token. And Chainlink is offering only one service (oracles) which DAPPNetwork offers.
With Zeus SDK LiquidApps.io offers an open source plug and play development platform/middleware. Github: https://github.com/liquidapps-io

Cardano FAQ - V2

Cardano FAQ
What is Cardano? Cardano is an open source highly secure "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work, which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. this was a major step forward for the E-cash concept.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms like Stella, Bitcoin, cardano - and so on. Also most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling.
Gen 3 blockchains are using Proof of Stake to ensure scaling, Sidechains to allow the platform to interact with other platforms, like ethereum and bitcoin, and also include smart contracts that are developer friendly.
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity working on Cardano is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain. (from https://www.cardano.org/en/help-support/)
What is the difference between PoS and PoW? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half the network agrees, then the transaction is validated. Proof-of-Work (PoW) happens when a miner solves an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool.
What is a stake-pool and how does it work? A stake pool is where the computing power of the network takes place. Currently there are 1200 registered stake pools while 300 are creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
Can I Stake my ADA right now? If you had ADA in a Yoroi or Daedalus wallet before November 2019 then yes, you can stake. However if you have just purchased some or it was held on an exchange, then you will need to wait until August 18 (hopefully) for pools to start creating blocks, and first staking rewards will be 5 days later.
Where do I stake my ADA? Daedalus Flight wallet - Or Daedalus ITN, and Yoroi Wallet (as a chrome extension) are the current best options.
What are the staking rewards now and what can I expect on a return in the future? At the moment the Incentivised Test Net (ITN) is delivering 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic. However it should not be completely dissimilar from the ITN, with most speculating 6%-10%pa compounding weekly….at this point there is no solid answer
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 100 pools with a 10,00ADA pledge will be overall less profitable than 1 pool with 1,000,000 ADA pledge. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atilia, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an American entrepreneur and cryptocurrency specialist. Charles is often cited in the media as the Co-founder of Ethereum, but only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? There is no official word specifically as to why Cardano is not on Coinbase, However there prevailing theory is that Coinbase requires the coins to be decentralised. and as Cardano is still being developed, it will not be added Shelley is released, or possibly never, it is totally up to coinbase. However Charles did mention in an AMA that IOG has been working with many exchanges for the Shelley rollout.
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki

Cardano FAQ - V1 - Feedback requested

Cardano FAQ
What is Cardano? - Cardano is an open source highly secure blockchain 3.0 project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IHOK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Amongst these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work, which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity working on Cardano is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain. (from https://www.cardano.org/en/help-support/)
What is the difference between PoS and PoW? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half the network agrees, then the transaction is validated. Proof-of-Work (PoW) happens when a miner solves an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano?
Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
Can I Stake my ADA right now? If you had ADA in a Yoroi or Daedalus wallet before November 2019 then yes, you can stake. However if you have just purchased some or it was held on an exchange, then you will need to wait until August 18 (hopefully) for the release of the full staking capability. Where do I stake my ADA? Daedalus Flight wallet - Or Daedalus ITN, and Yoroi Wallet (as a chrome extension) are the current best options.
What are the staking rewards now and what can I expect on a return in the future? At the moment the Incentivised Test Net (ITN) is delivering 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic. However it should not be completely dissimilar from the ITN, with most speculating 6%-10%pa compounding weekly….at this point there is no solid answer
What is a stake-pool and how does it work? A stake pool is where the computing power of the network takes place. Currently there are 1200 registered stake pools while 300 are creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 100 pools with a 10,00ADA pledge will be overall less profitable than 1 pool with 1,000,000 ADA pledge. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atilia, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an American entrepreneur and cryptocurrency specialist. Charles is often cited in the media as the Co-founder of Ethereum, but only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? Coinbase requires the coins to essentially be “finished” and as Cardano is still being developed, it will not be added until there is more development rolled out.
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.

https://preview.redd.it/ym11pxcxe9b51.png?width=1600&format=png&auto=webp&s=e24509d9e659bd7dcc707fe457ba35ad97d61746

  1. Introduction
With the blockchain community, there is currently some puzzlement regarding the Matic Mainnet launch. It was expected by many that the Matic Network would have substantially increased transaction history at this juncture. This expectation is likely to begin its exponential growth in a short period of time as will be explained in the next section. The Matic Network 2.0 sidechain build on the Ethereum blockchain is in its own rights a blockchain, but one that is closely associated and directly connected to the Ethereum 1.0 blockchain. In the same way that an artery connects all the blood vessels to the heart, in a single system, causing it to pump – Matic hybrid-proof-of-stake and Plasma-enabled sidechains connect Dapps to the sidechain which enables near-instant transactions for Ethereum / Matic Dapps at exceptionally low fees, enabling the realization of the mass-adoption dream.
📷
2. Clarifying The 3 Mainnet Phases / Stages / Steps
The Matic Mainnet is a 3 stage approach and not a single event as with other blockchains. Matic is not just a blockchain, it is a blockchain/sidechain vitally connected to the Ethereum Blockchain and cannot exist without it. This in itself creates complexities for the development team which have been needed to be resolved through highly innovative and creative software design strategies. For this reason, the Mainnet launch has been divided into three phases. The time frames for steps 2 & 3 have been provided below by Sandeep Nailwal (Matic COO & Co-Founder). The launch sequence is as follows:
📷
Note: According to Sandeep Nailwal, “only one or two applications have started minting on the sidechain even though the blockchain community trust the Matic guidelines.” However, this will change in the next few days as more Dapps will be deployed. The reason for this has been rigorous testing. Another reason is third party tooling which is in the process of being set up, For example, “ Portis just added Matic Network Mainnet to their documentation” (Sandeep Nailwal, July 6 2020). More information regarding Portis will be provided in section 4 below. It is important to understand that the onboarding process is speeding up each day and numerous Dapps will be minting on the Matic sidechain in the coming weeks.
📷
3. Portis Non-Custodial Wallet Connecting Dapps to Matic
Portis is a platform that provides a frictionless user experience for Ethereum Dapps
Portis is a web-based wallet built keeping easy user-onboarding in mind. It comes with a javascript SDK that integrates into the DApp and creates a local wallet-less experience for the user. Further, it handles setting up the wallet, transactions and gas fees. Like Metamask, it is non-custodial - users control their keys, Portis just stores them securely. But, unlike Metamask, it is integrated into the application and not the browser. Users have their keys associated with their login id and passwords (Matic Developer – Portis, 2020).
  • The Portis Wallet will enable many other Dapps to interact with the Matic Network simply and easily.
  • Users of Dapps can connect with and email address and password from any browser, on any device and from mobile phones
  • Portis accepts debit and Credit cards worldwide for those who do not have crypto – minimal KYC and no uploading of documents.
The addition, for example, of the third party tooling Portis Wallet will speed up the onboarding of many Matic partnership applications.
4. Unbond Period Reduced
Of concern to many Matic stakers and those wanting to participate was the unbond period for the tokens staked. The period to unbond until yesterday was 18-21 (at 424 checkpoints) days but is now 8-10 days (at 888 checkpoints) according to the announcement made of the 6th of July (Matic Official Announcements, 2020).
5. Matic to Ethereum Token Bridge Reduces Time From 7 days to 30 minutes
  • Currently, the time to transfer funds from the Matic Network to Ethereum is 7-days. This is for security reasons. This is for trustless token transfers. However, any third party can put up a trusted token bridge, where transfers can be instantaneous (Delroy Bosco – Matic Product Manager)
  • Delroy Bosco further has confirmed that a new token bridge that will be released by Matic within approximately the next four weeks will take the time down to 30 minutes (the time of each Matic Network checkpoint).
  • 6.Transaction Fees
It is well known that Ethereum fees are getting higher and transactions are currently expensive and sometimes slow due to the amount of applications onboarding Ethereum. Matic network provides high scalability and low fees – approximately 100 times less than Ethereum. This is an important consideration for businesses building their applications of the blockchain.
Fees to transfer from the Ethereum Blockchain to the Matic network are substantially lower than Eth1.0 fees and also from the Matic Network back to the Ethereum Blockchain. Businesses who desire to operate on the Matic network will have very low fees and only from time to time will need to pay Ethereum fees when withdrawing funds. However, the numerous day to day transactions will incur Matic Network fees.

The future of dApp development. The end of blockchain tribalism

The future of dApp development. The end of blockchain tribalism
If you are a dApp developer this is a must read!
As all the blockchains have their advantages and disadvantages there is no blockchain which will rule them all. Each blockchain will get congested as soon there are too much “mass adoption” dApps on it, which actually getting used. One blockchain is more decentralized, another more performant.
The solution are decentralized services which are validated and 100% ONchain. A platform layer where dApps can choose what they need, without important trade-offs for their applications. And everybody who want to offer a service, can offer them as a Service Provider. The DAPP services are the new (Amazon) Web Services but decentralized, affordable and for blockchains. Today the DAPP Network counts already 35 DSP’s (DAPP Service Providers) offering 120 services (packages) and counting…
The Internet of Blockchains - Enabled by the Universal Middleware of the DAPP Network
The DAPP Network is the first solution which offers this kind of decentralized services. And with the Chintai.io DAPP Resource Exchange where developers can rent DAPP tokens for an affordable price for 30 days, they can pay monthly with a ‘pay-as-you-go” model for their resources and scale their dApps step by step. And it doesn’t make a difference if it’s a new developed dApp or if somebody want to use services for an already existing dApp. If the dApp already exists on a specific blockchain, it can stay on that blockchain and nonetheless use services or scale without tradeoffs. No need any more to change to another blockchain thanks to LiquidLink.
What do you think will happen to the crypto space when companies and big enterprises start to realize that they are independent of any specific blockchain and that they can scale/tokenize their dApps 100% ONchain to an affordable price to mass adoption without any tradeoffs?
Get/Buy DAPP tokens on Bancor.network or Newdex.io before big exchanges start to list DAPP. Today DAPP is worth 0.015$ per token. The concept is in my opinion a breakthrough! Just think about Chainlink is today around 5$ per token. And Chainlink is offering only one service (oracles) which DAPPNetwork offers.
With Zeus SDK LiquidApps.io offers an open source plug and play development platform/middleware. Github: https://github.com/liquidapps-io

Showcase LiquidOracles, LiquidAccounts, LiquidScheduler, or vRAM in your dApps and you could win a grant of up to 300,000 DAPP tokens! https://medium.com/the-liquidapps-blog/announcing-the-dapp-network-grants-program-7b104e1ce1d6

LiquidOracles: Choose from different DSP’s low latency oracle services. LiquidOracles stands out by keeping SLAs and data verification on chain, protecting you from the risks of malicious or accidental failure. Protect your data streams from being modified by malicious parties. Decentralized and trustless, without needing a separate blockchain. LiquidOracles are a more generalized and flexible solution than other oracle solutions like Chainlink. They also do not have any limitations with gas fees or block times. For example, EOS Options (on Kylin) is currently calling multiple price feeds every 15 seconds using LiquidOracles and have also tweeted recently about their plans to update their oracle feeds every 1 second. Things like that just aren’t possible on Ethereum at this time. Working and already integrated product today in eosoptions.com, Equilibrium EOSDT stablecoin and Project Phoenix
DSPs (dApp Service Providers) could integrate Chainlinks as part of their data feeds, and Chainlink could utilize the DAPP Network to gain some additional advantages. Chainlink and DAPPNetwork are better together
LiquidScheduler: Set timed events. Free up resources when users become inactive. Schedule regular checks of data sources. Take advantage of options to make your application more resistant to unreliable providers and infrastructure failures. It’s a Cron-Like Task Scheduler Example: regularly update from oracle feed (Example all 15 seconds) Working and already integrated product today in eosoptions.com, Equilibrium EOSDT stablecoin and Project Phoenix
