Ethereum Researchers Reveal Casper Progress

Vlad Zamfir, a leading researcher at the Ethereum Foundation, and three of his colleagues released on Monday a draft of a white paper, which they believe is a step forward towards solving Ethereum’s scalability concerns through Proof of Stake (PoS).

The paper, titled “Introducing the ‘Minimal CBC Casper’ Family of Consensus Protocols," highlights Casper Correct-By-Construction (CBC), a decentralized consensus mechanism and protocol that is supposed to improve the PoS system.

The document was unveiled just days after Vitalik Buterin, co-founder of the Ethereum Foundation, discussed the “Serenity Protocol” during Devcon 4 in Prague. Serenity is a new blockchain, which Buterin called the true “realization of Casper.” Casper is the codename for Ethereum’s flavor of the proof of stake algorithm.

“There’s definitely a place in our heart and the roadmap’s heart for Casper CBC, [but only] when it becomes clear that there is a version that makes sense from an overhead view," said Buterin when presenting the new Ethereum roadmap at the opening of Devcon 4. 

The first iteration of the conference took place in 2014 in Berlin, and it was where the first visions of Ethereum were presented to core developers. Four years later, Devcon has become one of the most anticipated gatherings for blockchain developers.

Ethereum has been divided by the community into four phases of release: Frontier, Homestead, Metropolis, and now Serenity. Serenity promises speed and scalability like no other project, “hopefully 1,000 times higher scalability," according to Vitalik.

“Serenity is a realization of all of these different strands of research that we have been spending all of our time on for the last four years," he added. "This includes Casper, and not just Hybrid Casper: 100% organic, genuine, pure Casper, sharding, EWASM, and other protocol research ideas.”
