On January 19, news broke that there is a clear disagreement between the core figures of the two major ecosystems, Solana and Ethereum, regarding whether blockchain underlying protocols should "continue to evolve" or "tend to become rigid." Anatoly Yakovenko, co-founder of Solana, publicly questioned Ethereum founder Vitalik Buterin's long-term development philosophy for blockchain, sparking widespread industry discussion. The spark for the debate was Vitalik Buterin's recent view on Ethereum's "exit test." He believes that a mature blockchain protocol should develop to a stage where it can cease frequent upgrades and still operate stably over the long term, known as "protocol rigidity." In this state, the core value of the protocol no longer depends on future, yet-to-be-implemented features, but instead possesses reliability similar to infrastructure.
