7 Days Left Until the Great Bitcoin - news.bitcoin.com

If you've seen the new Forbes video from the sushi meet up, then you've seen our team and our new app. Introducing ZeroBlock, an app for realtime market data and news aggregation (including r/bitcoin!).

Hello bitcoin! We are the ZeroBlock team. Bitcoin is going mainstream, and its time for a serious bitcoin app. Our new app was finally approved a few hours ago - it's the slickest bitcoin app to hit the public.
The first iteration includes real time Mt. Gox price and Blockchain data. Further, the app aggregates bitcoin articles from 5 different sources (including bitcoin posts).
If you are like us, then you'll be opening this app every 10 seconds to watch the market and look for new Bitcoin publications. We would be honored to have bitcoin's feedback as well.
Our future plans are extremely ambitious. Within the next 7-14 days we will push an update that includes the following:
For all you Android users out there, don't worry, we are working on app for you as well. Website in development. Other surprises in development. Tell us what you want. We will be at the Bitcoin conference in San Jose if you'd like to meet up with us.
An IAMA from the team coming soon! Keep an eye out.

ZeroBlock launches the first real time market data and cross-platform news aggregator for Bitcoin

Many of you have already know us from our iOS app. We've recently undergone some extensive upgrades to the zeroblock network. We are now officially the first cross-platform news aggregator network. iIf your page is having trouble loading, please refresh. Your browser is connecting directly to Mt.Gox's websocket, which sometimes doesn't load properly. We are working on fixing this issue asap.
Web: www.zeroblock.com
iOS: www.mobile.zeroblock.com Overview (Thanks to MonCorpus)
Android: 2 Android developers were just brought onto the team, will take ~1-2 months
We've been working with Andrew Le, our new in house web developer the last month to create our web platform. You can check out his portfolio at http://andrewle.com/work/. Our web platform has many of the features you enjoy with the iOS platform, however we are continually working on upgrade the site to be a perfect compliment. ZeroBlock will be the only network with the capability of reaching every Bitcoin user instantly, no matter what device they are on.
We've added some new features to the mobile app:
These features are in addition to what the mobile app already offers:

WTF, ZeroBlock...? Terrible New Website: PUT IT BACK HOW IT WAS!

Hey I have not seen any mention of this anywhere else but WTF has blockchain.info done to the ZeroBlock web page?
Main site is just linking to the phone apps now, and the NEWS aggregator list/page is TERRIBLE. The PRICE CHART sucks hard too, this new page is nothing at all like the phone app, which (thankfully) is still working the same.
I like keeping up on bitcoin news and info via the web page AS WELL as the phone app, but this change is a disaster.
Hey Blockchain: PUT ZEROBLOCK BACK HOW IT WAS!!!
Anyone else WITH ME on this?
Does anyone actually LIKE the new page???

Is the legendary Zeroblock app officially dead? :-(

Remember that legendary zeroblock app that with only a few minimalist swipes would give you a 360 degree view of Bitcoin, including chart, ticker, price notifications, difficulty, country money supply ranking, next difficulty days, etc.! It was simply the best bitcoin ticker app.
Well, it seems Zeroblock app for iOS is longer responding and it's showing a blank screen after a few days of the displayed price getting stuck.
Zeroblock was so unique that it even allowed you to opt in/out your news feed from different news sources, including Bitcoin reddit and bitcointalk forums!!. Sadly enough, I don't know of any other iOS app that includes the ability to configure/receive those feeds plus all the features in the same clean, minimalist app.
Does anyone know if this is finally the end of Zeroblock app or a way to connect with the development team? I really hope there's a light at the end of the tunnel or that we find a way to chip in to resucite it. It was truly a treasure of an app.

What are your favorite apps for bitcoin news?

Zeroblock was the main app I used for bitcoin news but for the past few days there's no news listed. Looking for a new app.

Countering Selfish Mining in Blockchains

arXiv:1811.09943
Date: 2018-12-17
Author(s): Muhammad Saad, Laurent Njilla, Charles Kamhoua, Aziz Mohaisen

Link to Paper


Abstract
Selfish mining is a well known vulnerability in blockchains exploited by miners to steal block rewards. In this paper, we explore a new form of selfish mining attack that guarantees high rewards with low cost. We show the feasibility of this attack facilitated by recent developments in blockchain technology opening new attack avenues. By outlining the limitations of existing countermeasures, we highlight a need for new defense strategies to counter this attack, and leverage key system parameters in blockchain applications to propose an algorithm that enforces fair mining. We use the expected transaction confirmation height and block publishing height to detect selfish mining behavior and develop a network-wide defense mechanism to disincentivize selfish miners. Our design involves a simple modifications to transactions' data structure in order to obtain a "truth state" used to catch the selfish miners and prevent honest miners from losing block rewards.

4/17/14 Video News - Bitcoin.com, SecondMarket, Walmart, Ron Paul & Dogecon SF

Video: http://www.moneyandtech.com/apr17-news-update/
Catch up with today's top news stories in Money & Tech:
Blockchain.info announced today that it has struck a five year deal to exclusively manage the domain Bitcoin.com. The domain's sleek new homepage now features three main links for the Blockchain wallet service, Zeroblock news and charts, as well as a search function to explore the rest of Blockchain.info. As stated in their announcement, this is part of the mission quote "to create new learning experiences and introduce millions of users to Bitcoin."
SecondMarket has taken another step towards the ultimate launch of America’s first fully regulated Bitcoin Exchange, releasing a new website for their quote “Experienced, Full Service Bitcoin Trading Services”. CEO Barry Silbert says he hopes to launch the fully licensed exchange for all compliant users this summer.
Walmart has announced the April 24th launch of their new Walmart-2-Walmart Money Transfer Service, in partnership with global remittances company Ria, which could clarify their decision to cut ties with Gyft.com. The new low-cost service will allow customers to transfer money between the over 4,000 Walmart stores nationwide, and is aimed at helping the almost 28 percent of Americans who are either underbanked or unbanked and rely on money transfers.
ZaZZZ, billed as the first Marijuana vending machine in the US, will also be accepting bitcoin. Since the legalization of marijuana in 2012, Bitcoin has become popular among dispensary owners who have been rejected by traditional financial institutions. The ZaZZZ machine however is far from an anonymous way to buy the newly legal drug, as it is equiped with an ID reader, and a video camera.
Former Congressman Ron Paul took to popular question-and-answer website Quora to express his thoughts about bitcoin, saying "Though I don’t personally believe that Bitcoin is true money, it should be perfectly legal and there should be no restrictions on it... For this to operate, we need to have freedom from government intervention when it comes to the Internet."
Dogecoin creator Jackson Palmer and the Dogecoin Foundation are putting together Dogecon SF on April 25th in San Francisco, in partnership with Follow The Coin. The event’s organizers expect it to be the largest dogecoin gathering yet, lining up celebrity speakers such as litecoin creator Charlie Lee, Doge tip bot co-founder David Dvorak, and bitcoin evangelist Andreas Antonopoulos.
We continue bringing you interviews from the recent Inside Bitcoins New York conference today with BitAngels Managing Director David Johnston, and BitGo CEO Will O’Brien. Watch those, and then enjoy the official trailer for the bitcoin documentary, The Rise And Rise Of Bitcoin, which premieres at the Tribeca film festival next week.

I suggest posting links to good replies we make at /r/bitcoin here. That way we can monitor their censorship better.

Furthermore I think Google, Zeroblock, and others are linking to /bitcoin and not the alternative forums. There was some data that supports that view. In other words, new users are funneled into the censored forum surprise surprise. So we need a consistent escape hatch. I am not suggesting doing anything that violates any rules or creates an undue conflict. Just link to your posts there then we can point it out each and every time the censor something. What do you think?
