Ethereum Researcher Announces CBC Casper Draft Paper

Ethereum Foundation researcher Vlad Zamfir took to Twitter on 4 November to announce the draft paper: Introducing the ‘Minimal CBC Casper’ Family of Consensus Protocol

The draft paper was made by Vlad Zamfir, Nate Rush, Aditya Asgaonkar, and Georgios Piliouras to give interested readers a clear-cut and basic understanding of the proof of asynchronous Byzantine-fault-tolerant safety CBC Casper.

Correct-by-Construction (CBC) Casper is a different protocol from the Friendly Finality Gadget Casper of Vitalik Buterin.

What is CBC Casper?

The paper opens with an overview of what CBC Casper is:

CBC Casper is a family of ‘correct-by-construction’ consensus protocols that share the same proof of asynchronous, Byzantine fault tolerant consensus safety. We describe this family of protocols by defining their protocol states and protocol state transitions, and then we provide a proof of Byzantine fault tolerant consensus safety for the entire Minimal CBC Casper family of protocols

The CBC Casper draft paper

It also mentioned that the material is meant to be introductory and educational.

The paper demonstrated that members of a family of consensus protocols has asynchronous, Byzantine-fault-tolerant consensus safety.

‘Furthermore, we’ve given examples of members of the family of increasing complexity to demonstrate the power and flexibility of our approach to correct-by-construction consensus protocol design.’

For a deeper understanding of CBC Casper, the detailed draft paper can be read from Github in full.

Bitcoin Twitter Engagement Tumbles to Two Year Lows as Sentiment Turns Bearish

Love it or hate it, twitter is an integral part of the crypto scene. Sentiment is often gauged by reaction from Bitcoin market analysts and industry insiders who spend their time on the social media platform. Recent charts indicate that overall engagement has declined back to levels as low those two years ago. Tweeters Go Silent on Bitcoin The irony is that a lot of what goes on in the cryptoverse revolves around postings on a centralized social media platform. This maybe testament to the immaturity of the scene in that tribalism and infantile bickering is still rife on the platform. The bottom line is that we all want the same thing, and that is the growth of Bitcoin and crypto asset ecosystem for a decentralized financial future. According to ‘Skew Markets’ twitter engagement for Bitcoin has fallen to lows not seen for two years. Looks like the bottom is in for the Twitter counts – hodling the fort! — skew (@skewdotcom) November 20, 2019 This may not be the case for other crypto assets but Bitcoin at least appears to have fallen out of flavor on the social media platform. The peak came with price in early 2018 when daily tweets topped 150k. Today they’re down below the 20k level according to the chart. It could be that the space has evolved beyond twitter which would be a good thing since the whole scene there is a bit of a circus, as anyone that uses the platform would agree. Intrusive advertising and unfettered spam and scam attempts are rife which does not make it the best stage for an industry advocating the adoption of decentralized digital assets. Just like Facebook, twitter controls what people see in their feeds and the whole stream of information is becoming more irrelevant which could explain the lack of engagement. ‘Influencers’ as they’re so called are often only interested in promoting their chosen crypto asset, be it Bitcoin, BCH, BSV, ETH, XRP or whatever. That said there are a few professional analysts and industry insiders worth following if you have the inclination to sort the wheat from the huge pile of twitter chaff. BTC Bears Back In Town? With Bitcoin tumbling back to $8,000 the entire scene has turned bearish again with wannabe analysts shouting about further dumps to $5k or below. There is also a lot of FUD about miner capitulation as the halving approaches and the possibility of the first ever bearish lead up to the event. One of twitter’s more respected analysts and researchers, ‘PlanB’ has noted that this has also happened before. “Fact is that 6 months before 2012 halving we were above difficulty model value, in 2016 below, and now spot on.” Lot of FUD about miner capitulation. Fact is that 6 months before 2012 halving we were above difficulty model value, in 2016 below, and now spot on. Also, I am looking at +2% difficulty adjustment next Thursday. Cheer up! — PlanB (@100trillionUSD) November 19, 2019 It could be that twitter engagement is indicative of falling market sentiment, but back when tweet levels were this low in January 2017, BTC was priced below $1,000 and today the scene is very different.

Leave.EU chairman’s Twitter account hacked, private messages leaked

A hacker hijacked the Twitter account of Arron Banks, chairman of the pro-Brexit UK political campaign organization Leave.EU, and leaked his private message history online earlier this week. The BBC yesterday reported that the culprit had access to thousands of private messages that had been sent and received by Banks over several years. The Register further reported that the hacked Twitter account was used to spread links to a download page that hosted a dump of the messages. Banks’ account has been suspended and the file is reportedly no longer available online. The Guardian reported that the attack involved illegal access to Banks’s email address, and quoted a Leave.EU spokesman as saying that a SIM swap also took place. Banks directed his outrage toward Twitter, accusing the social media company of mounting an inadequate response. “I became aware last night that my Twitter account had been hacked and that persons involved have posted personal data obtained illegally via Twitter,” Banks wrote on the official Twitter page of Leave.EU. “The matter has been reported to the police.” “Twitter were [sic] notified 12 hours ago, and despite repeated requests they have taken no action to deactivate the account or remove the illegal data downloads,” Banks continued. “Despite the obvious lack of security at Twitter related to personal data, they have deliberately chosen to leave personal data in the public domain.” Per the BBC, Twitter said it had “taken steps to secure the compromised account” and “will continue to take firm enforcement action in line with our policy which strictly prohibits the distribution on our service of materials obtained through hacking.” In February 2019, the UK’s Information Committer’s Office levied a £120,000 fine against Leave.EU and Eldon Insurance — a company founded and owned by Banks — for breaching data protection laws. Leave.EU reportedly sent Eldon customers political marketing messages without their consent, and Eldon sent unsolicited emails offering discounts to Leave.EU subscribers.
