CasperLabs Debuts First Spec for a Provably Live, Safe CBC Casper Protocol 

Published

CasperLabs updates
Medha Parlikar, CTO of CasperLabs, will be presenting CasperLabs Highway and its significance at the San Francisco Blockchain Week. The team has reached out to CryptoTapas to share the news about their CapserLabs Highway.

The First Specification for a Provably Live and Secure CBC Casper Protocol

In consensus protocol literature, there are two critical security properties: safety and liveness. A protocol is safe if it will not make inconsistent decisions. A protocol is live if it is guaranteed to eventually make a decision. Making proof-of-stake (PoS) both safe and live for a decentralized network isn’t easy. One of the first breakthroughs to address these issues was published in a research paper titled “CBC Casper” by Ethereum Researcher Vlad Zamfir. While this initial research on the correct-by-construction (CBC) Casper family of protocols provided a leading-edge framework to address safety, it did not address liveness.

At CasperLabs, we have not only been researching on imminent issues around scalability and energy consumption, but have also been extending on Vlad Zamfir’s existing CBC Casper research to push the boundaries of our industry together.

Today, we are very excited to introduce CasperLabs Highway, the first specification for a provably live and safe consensus protocol within the CBC Casper framework.

We are releasing the protocol specification free to the community under an open-source license. The complete research paper is also available here.

Why CasperLabs Highway is Significant

Highway extends CBC Casper research in two ways.

First, the consensus protocol provides a novel, efficient way of detecting safety at different thresholds.

Second, Highway provides the first-ever specification for a liveness strategy in the CBC Casper framework. In other words, Highway prescribes a strategy for when participants in the network should create protocol messages and proves that the strategy results in the protocol being live.




How CasperLabs Highway Works

Highway utilizes an innovative approach that offers a new “summit” construction for finality which consist of “levels” of agreement. In order to effectively achieve liveness, the design uses a pseudorandom leader sequence with a dynamic round length system.

To understand how this works, let’s start with a simplified model. Time is divided up into rounds; during each round there is a leader who starts the message production. Others wait until they receive the leader’s message, before producing one themselves. Then, near the end of a round everyone sends another message. At each stage another level of agreement is being produced, eventually leading to a summit which can be considered a decision.

However, fixed length rounds are not practical in real systems, so in Highway we make them dynamic. To achieve this, we imagined a literal highway (well, a mathematical highway). On this highway, movement takes place in the form of hops, while the speed of all cars is constant. In any given lane n a car makes 2^n hops on a distance of one meter. Therefore, if you switch to the lane on your left, you increase the frequency of hopping x2. If you switch to the lane on your right, you decrease the frequency x2. Cars from the lane on your left meet you at every jump you make, and cars on your right meet you only every second hop. These “hops” are ticks, and each “meter” a round passes. Thus, the length of a round depends on what lane you are in.

By releasing CasperLabs Highway to the public via an open source license, we hope to inspire further innovation for the benefit of all.

We want your feedback — the good and the “ugly.” As an industry, we need discourse of ideas and critical analysis so we can all move forward together. Working together, we believe we can solve our industry’s challenges and help blockchain networks achieve widespread adoption for businesses and consumers.

What keeps this whole crypto space exciting?  There is not a single boring week.  We have been tracking this space since 2017 and we are yet to find a boring week in Crypto.  

Whether it is filled with FOMO or FUD, there is always excitement of sorts.  Let’s see what’s happening this week.

US Senate Banking Committee held a hearing on digital dollar

China’s digital yuan race is pushing the US to rethink its digital dollar timeline.  Senator Tom Cotton (R-Ark.) stated, “The U.S. needs a digital dollar…The U.S. dollar has to keep earning that place in the global payments system. It has to be better than bitcoin … it has to be better than a digital yuan.”  While Facebook’s Libra is taking center stage of discussion whenever stable-coins are brought up in front of congress, the emphasis during this hearing was to develop a digital dollar controlled by the government and better than existing stable-coins.

NYDIG discloses $190 Million Fund 

“New York Digital Investment Group (NYDIG) today disclosed, in an SEC filing that it closed a $190 million bitcoin fund. The NYDIG Institutional Bitcoin Fund LP, reports that it has 24 unnamed investors and is  exempt under Rule 506(b) of the Regulation D safe harbor protections established in 2013,” according to Forbes.  This is quite bullish considering that NYDIG also had a similar fund worth $140 Million last month.

You can buy Bitcoin at 3500 Post Offices in Australia

Australians can now buy Bitcoin at any of its 3500 Post Offices across Australia.  Thanks to the partnership of Australia Post with Bitcoin.com.au, Australians can now simply use cash or EFTPOS payments for digital currencies.  “Our mission is to make Bitcoin safe and easy for every Australian”, says Holger Arians, CEO of Bitcoin.com.au, “for many people, paying for Bitcoin at an Australia Post office feels safer than transferring funds online—particularly for first-time buyers. We’re proud of this partnership and would like to thank Australia Post for their continued openness to new technologies.”  This is a tremendous news in the broader Bitcoin movement as this helps Australians to access Bitcoin directly without having to transfer money online or having to open accounts with random exchanges.

Visa partners with Bitcoin startup Zap

Visa partners Bitcoin ZapZap, a bitcoin startup, is building a product called Strike that enables bitcoin lightning payments without needing users to set up a bitcoin wallet.  Visa is now partnering with Zap to bring the lightning fast payments on Strike platform through Visa.  Visa has been aggressively partnering with companies in the crypto space.  It even filed for a patent in the cryptocurrency payment system.

Supreme Court sets ‘limits’ on SECs powers to assess digorgements (penalties)

Securities Exchange Commission’s ‘extent’ of power has been challenged by the Supreme Court. A ruling that SEC cannot assess digorgements beyond the ‘illicit gains’ could help a lot of blockchain and crypto startups with much needed relief knowing that SEC cannot assess penalties beyond what was raised from the investors minus required expenses.  For instance, before this ruling, SEC could charge a company disgorgements that are 100% or more of the money raised from the investors, this devastated many up and coming entrepreneurs who may have spent part of the proceedings in expenses such as legal expenses, salaries, administrative expenses, etc.,   Supreme Court also ruled that the disgorgements should be used for the benefit of victims and not solely for the SEC’s fund.

KPMG’s Chain Fusion To Help Manage Crypto And Traditional Assets Over Public And Private Blockchain Networks

New York proposes new licensing rules to facilitate crypto businesses

In a good news from the big apple, New York financial regulators proposed new licensing rules for the crypto businesses that would make it easier for businesses to offer services and use cryptocurrencies.  The New York Post reported that  The New York State Department of Financial Services (NYDFS) proposed framework would allow companies that want to engage in virtual currency business activity in the state to obtain a conditional license, through which they would collaborate with fully licensed companies.”  Regulators in other States in the US are trying to catch up with regulatory framework to lure blockchain and crypto organizations, NY is heating up the space by making it easier for companies to operate in the State.  Being the financial capital of the US and the world, this is a welcoming stance from the State for the crypto businesses.

Bithumb Exchange to Reportedly File for IPO in South Korea

Bithumb NewsBitcoin and Cryptocurrencies are going mainstream.  We have seen companies that operate in the blockchain and crypto space going IPO instead of ICO.  ICOs have historically been limited to those who have been in the crypto space while IPOs are much more stringent to follow through with registrations, approvals and investor selection.  Bithumb, one of the popular exchanges is rumored to be going the IPO route.  Google translation of the news reads that “It is expected that Bitsum’s IPO will be an event in which discussions on virtual currency and even blockchain will spread in our society and economy. From whether or not a virtual currency can be recognized as a real value, it is highly likely that there will be controversy over business feasibility, industrial value, and meaning. In addition, virtual currency tax issues, business continuity, asset handling, and investor protection are also issues to consider.”

Bitfinex Launches Open-Source Crypto-Powered Streaming Protocol

bitfinex newsBitfinex launched an open-source crypto powered streaming protocol called Dazaar.
