Vitalik Buterin Releases Updated Roadmap for ETH 2.0
Ethereum co-founder Vitalik Buterin has released a “plausible roadmap” for the ETH 2.0 update. In a post titled “Endgame,” Buterin elaborated on the ETH team’s thought process regarding how they are approaching the switch to a proof of stake consensus protocol.
“Consider the average ‘big block chain’ - very high block frequency, very high block size, many thousands of transactions per second, but also highly centralized: because the blocks are so big, only a few dozen or few hundred nodes can afford to run a fully participating node that can create blocks or verify the existing chain. What would it take to make such a chain acceptably trustless and censorship resistant, at least by my standards,” said Buterin in his blog post.
Buterin then goes on to elaborate on a roadmap regarding the process including adding a second tier of staking, fraud proofs called “ZK-SNARKs” that can expedite the process of validating blocks, data availability sampling, and secondary transaction channels.
Essentially there are many factors to consider regarding the balance between decentralization, network scalability, and security. Buterin states that while there are many networks pushing security and scalability, there is an increasing amount of centralization in the space where networks are forgoing decentralization in an effort to accommodate more users and maintain network security.
