Ethereum researcher Justin Drake has sparked speculation about ETH 3.0 upgrades through a recent post announcing an 'ambitious' initiative that could address Ethereum's scalability challenges. Expected to be presented at Devcon on November 12, the proposal may involve a redesign of the consensus layer and potentially introduce a native zero-knowledge Ethereum Virtual Machine (zkEVM). Community reactions have varied, with some expressing excitement over rumors of achieving one-second block times and arbitrary scalability. Doug Colkitt from Ambient Finance praised the zkEVM concept, suggesting it could eliminate gas limits altogether. Meanwhile, Consensys CEO Joe Lubin remarked on the potential return to execution sharding, leveraging advancements in zero-knowledge technology to enhance performance and scalability. While there is optimism about Ethereum's future capabilities, Lubin acknowledged that full implementation of these solutions could take several years.
