Vitalik's Tweet Storm - History and state of Ethereum's Casper research

acryptoverse (41)in #ethereum • 6 years ago

Vitalik Buterin, in a series of 75 Tweets, gave details on the history and status of Ethereum's Casper research project. Casper is a proof-of-stake protocol currently being developed to provide Ethereum as a way to scale efficiently enough to power, for example, a gargantuan number of transactions per second that a traditional credit card must be able to handle.

The TL;DR version:
Buterin notes in his description of the process that he and his partner Vlad Zamfir essentially took two different approaches to solving the problem, Buterin favoring Casper FFG (Casper the Friendly Finality Gadget), and Vlad pursuing Casper CBC (Correct by Construction). CBC came about from Zamfir's research on the underlying mechanisms behind consensus algorithms, and largely is a new theoretical invention of his.

Both engineers and the Ethereum team at large have been developing the protocols separately, and both have made great strides forward, such that at this point they have become two different projects.

Buterin ended the discussion on Casper noting that both projects in fact are close to deployment, only needing 'formal proofs, refinements to the specification, and ongoing progress on implementation' before they are ready to be unleashed.
