Ethereum Foundation researcher Justin Drake proposed a new consensus layer upgrade proposal 'Beam Chain' at the Devcon conference, referred to by the community as 'Ethereum 3.0'. This proposal aims to achieve faster block times, lower validator staking requirements, 'chain-based snarkifaction', and quantum-safe improvements. Doug Colkitt, founder of Ambient Finance, pointed out that the localization of zkEVM could completely eliminate gas limits, allowing nodes to only verify snarks, theoretically achieving infinite scalability for L1. However, this proposal could lead to further centralization of block construction. Beam Chain is expected to have specifications drawn up in 2025, begin construction in 2026, and enter full testing in 2027. (The Block)
