Cardano Founder Blasts Bitcoin Developers for Attacking PoS Mechanism
Song mentioned networks that used a matching algorithm, such as Cardano, Ethereum, and other Proof-of-Stake systems. He said that because these systems could not resolve the Byzantine General's problem, they failed to ensure true decentralization.
Vitalik Buterin Criticizes Bitcoin developer
It appears that Buterin did not view the statement favorably since he is now striving to convert Ethereum from a Proof-of-Work (PoW) consensus process to a Proof-Stake mechanism. The Ethereum developer replied to the tweet more politely by saying:
"Pro-tip: if there's a long-established tradition of people debating A vs B based on deep arguments touching on math, economics and moral philosophy, and you come along saying 'B is dumb because of a one-line technicality involving definitions', you're probably wrong."
Byzantine General's Problem
Many diverse networks have substantial challenges due to the Byzantine Generals' Dilemma, especially ones that rely on consensus. The problem arises when numerous individuals must come to an understanding for a system to work effectively, but frequently none of these actors trust one another. However, the immutable public record feature that Bitcoin introduced was the first blockchain to address the problem by lowering the incentive for dishonest users to join the network.
