Ethereum Researcher Announces CBC Casper Draft Paper

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.

Vitalik Buterin Sees Ethereum (ETH) Dominance Fading… And He’s Not The Only One

Vitalik Claims Ethereum Is Losing Its Lead “To Some Extent” Earlier this week, the one and only Vitalik Buterin sat down with prominent crypto journalist Laura Shin to talk all things Ethereum. In the interview, this being the first live episode of “Unchained,” Buterin was surprisingly candid, letting a few things slip out of his lips that may have caught some on the back foot. According to BreakerMag, Shin started it out with a toughie: “is Ethereum losing its lead?” Surprisingly, Buterin conceded, remarking that yes, Ethereum is losing its command over the smart contract blockchain ecosystem “to some extent.” The Russian-Canadian coder chalks this up to his brainchild’s nascency, explaining that as the industry swells, there will naturally be competitors that rear their heads. He adds that time gives projects time to build off their predecessors. The 26-year-old programming wiz goes on to touch on potential competitors. Polkadot, a yet-to-launch crypto project that raised a purported $100 million+. Buterin explains that he doesn’t see the blockchain replacing his own. Yet, he explains that he wouldn’t be entirely disheartened if the privacy-centric ZCash or even Ethereum Classic were to usurp his project’s own hegemony. On the other hand, he poked fun at Tron, explaining that if the Justin Sun-run venture manages to take over Ethereum, he ” will have lost a certain amount of hope for humanity.” Losing Steam Buterin isn’t the first to have brought up issues with the narrative that Ethereum will always be the go-to platform for decentralized applications. Kyle Samani, the co-founder and managing partner of Multicoin Capital, noted that well-funded, high-potential blockchains could eventually pose a threat to Ethereum’s multi-year supremacy. The Multicoin executive noted that Cosmos and the a16z-backed Dfinity, two projects that found their roots in 2017, could take a large piece of the smart contract development and deployment pie. World-renowned venture capitalist Fred Wilson echoed this thesis. In a blog post, Wilson, the co-founder of Union Square, remarked that “‘next-gen’ smart contract platforms” will begin to ship and challenge the long-standing leader in 2019, especially in terms of its leadership in this “super important area in the crypto sector.” In a recent Forbes interview, Alex Sunnarborg, a Tetras Capital representative, noted that recent layoffs at Consensus Systems, better known as ConsenSys, should have a negative effect on the broader Ethereum ecosystem. He added that the fact ConsenSys is an integral part of this subsector and underwent purportedly drastic staff cuts should have some worried. Generalizing DApps and products on the platform, Sunnarborg explained that many promising offerings have yet to launch, and the ones that have are “pretty difficult to use” and have little-to-zero active users. Case in point, the Tetras capital founding partner drew attention to the mere $40,000 currently staked on Augur, a multi-million dollar ICO. Thus, he claimed: “There’s this massive disconnect between how much money is still tied up in these projects and how much people actually use them.” Sunnarborg added that Ethereum may also become pressured by competition blockchains, like Dfinity or Polkadot, along with the fact that the chain’s development is losing momentum and steam.

Ethereum [ETH]’s Vitalik Buterin says he will lose certain amount of hope for humanity if Tron overtook Ethereum

Vitalik Buterin, the co-founder of Ethereum [ETH], spoke about other blockchains taking the lead, during an interview with Laura Shin at the Unchained Live event. He also named the project he thought was a competition to Ethereum. According to a report by BreakMag, Vitalik Buterin spoke about whether he was worried about the world’s second largest cryptocurrency losing its position in the space, in light of the emergence of new projects such as Polkadot. To this, he stated that new projects were usually optimistic in their initial days, citing the example of Bitcoin sidechains. The initial conception of Bitcoin sidechains was that it was “going to kill Ethereum,” he said. However, in reality, “there’s really only working Bitcoin sidechain.” Buterin concluded by stating that he was “definitely not worried” about projects such as Polkadot replacing Ethereum. Laura Shin also questioned Buterin on whether he would personally be upset if another blockchain took the lead. It would depend on the blockchain, he said, adding that relations were friendly between ZCash and even, Ethereum Classic. However, if Tron were to take over Ethereum, Buterin stated that he would “have lost a certain amount of hope for humanity, not nearly all.” Vitalik Buterin also spoke about the project he believed was the “most promising competitor” for Ethereum. He said,  “Dfinity. Dominic [Williams, the president and chief scientist of Dfinity] and I use the aspirational term ‘sister network.” During the interview, he also addressed the question of whether he was worried about Ethereum’s token sale being deemed as a securities sale. Buterin replied in the negative, stating that the Foundation’s legal team was paying close attention to it.

Surf Into Cybersecurity @ Twitter

Surf Into Cybersecurity @ Twitter:11 questions with CISO Mike Convertino, a highly decorated U.S. Air Force Colonel. - Part of Sensei School’s Meet-A-Pro interview series.Sunny Pedeva, Co-founder at Sensei School, got to chat with Mike Convertino, Chief Information Security Officer (CISO) @Twitter.Previously he was VP & CTO of Security Products at F5 Networks where he guided and managed the core intellectual property and technologies, as well as CISO & VP for Information Security at Crowdstrike. Just before that he was Microsoft’s Senior Director of Network Security, responsible for security automation development, intrusion detection and digital forensic investigations.Mike is also highly decorated retired U.S. Air Force Colonel and was last assigned as Commander of the 318th Information Operations Group responsible for the creation and operational employment of U.S. Air Force information operations capabilities globally.Sensei School: Why did you get into security?Mike Convertino: I got into security through my interest in electronics and engineering. Phone switches were particularly interesting to me at a very young age. Since they are basically computers that could respond to remote commands, I loved to tinker with them.Sensei School: What is Twitter’s security strategy in one sentence?Mike Convertino: Protect our users personal data and ensure that people on the platform are able to speak their minds safely in an environment of healthy conversations.Sensei School: How do you deal with threats at Twitter?Mike Convertino: Our platform infrastructure is massive and the threats we think about and work to defend against include both data theft and manipulation of the conversation on our platform. Many of our defenses at scale are embedded in the platform itself to prevent direct hacking, halt bots, troll farms and others who want to have an outsized impact on conversations. The privacy and the safety of the people who use Twitter is our top priority, and we are continuously working to defend it.Sensei School: What have been your biggest insights this past year?Mike Convertino: As new technologies such as Machine Learning become more and more intelligent, I’ve seen industry dealing with new types of threats that we haven’t seen before. Making sure that basic server hardware is not vulnerable is a challenge for companies both in terms of server load and implementation costs.The marketplace for attack tools has increased as well, as costs have gone down and “attack infrastructure as a service” such as a set of bots is becoming more available.Sensei School: What are some under the radar trends you’ve noticed?Mike Convertino: One of the trends we’ve seen on the heightened risk in the banking space as bad actors search for ways to exploit online systems. The marketplace for attack tools has increased as well, as costs have gone down and “attack infrastructure as a service” such as a set of bots is becoming more available.Sensei School: Why do people and companies underestimate the risk of being hacked / breached?To put it simply, often times they just aren’t aware of how much is really going on.Mike Convertino: To put it simply, often times they just aren’t aware of how much is really going on. The public generally views reports of attacks and data losses as individual events which aren’t related. The problem with that is that they actually are related to the design of the technologies. It’s important for companies to invest appropriately in threat intelligence and study where their vulnerabilities may lie.Sensei School: How should small businesses address cybersecurity?Mike Convertino: Small businesses should concentrate on their core business focus and outsource most of security. Some other things small businesses should consider is investing in services and technologies which will automatically block threats without a lot of human intervention. Purchasing cyber insurance coverage and making sure you have an incident response contractor on retainer are other things which they should look into.Sensei School: How can we increase cybercrime reporting numbers other than legislation?Mike Convertino: There isn’t actually a very well-known clearing house to post information about when individuals get hacked. There are many niche sites for specific acts like email takeovers, but no easy-to-use site for the general public. Creating one and publicizing it would help get general numbers up.Sensei School: What’s your take on cyber insurance?Mike Convertino: It can help companies with paying claims, defending against lawsuits and incident remediation and recovery. Some insurance companies also offer “reputation repair/recovery services” which can help to reestablish trust with users, customers and regulators.Sensei School: What would you advise people looking to get into the industry?Mike Convertino: If you are already in an IT or development-related field, check out different security forums for explanations of how attacks are launched and why they are effective. Sign up for a few classes with a college or university that has a cybersecurity degree program. Get involved in the community by going to conferences to meet people already in the field and make some connections. Getting a mentor in the space is a real help.Sensei School: What does Twitter look for in security candidates?Mike Convertino: We put a premium on looking for diverse backgrounds in an effort to foster different approaches to catching new and novel attacks. The hacking community is very diverse and comes up with some really unexpected and creative ways to break in. Our success depends on having that same level of diversity.Mike is on Twitter @mikeconvertino. Currently open security & tech positions @Twitter.Follow the Meet-A-Pro interview series @SenseiSchool on Twitter.We feature notable professionals in different fields from around the world, who share their insights and knowledge.
