ENS Labs has announced the cancellation of its Namechain project, a Layer 2 blockchain initially planned for the ENSv2 upgrade, opting instead to deploy ENSv2 exclusively on the Ethereum mainnet. This strategic shift reflects confidence in Ethereum's scaling capabilities, particularly following the adoption of EIP-4844, which has significantly reduced gas fees and improved mainnet efficiency. The decision underscores the benefits of leveraging Ethereum's robust security and decentralization, avoiding the complexities and risks associated with operating a separate Layer 2 chain. ENS Labs' move aligns with Ethereum co-founder Vitalik Buterin's recent emphasis on maintaining core infrastructure on the mainnet for enhanced security and decentralization. This pivot is seen as a pragmatic response to the evolving Ethereum ecosystem, ensuring ENS remains a secure and accessible Web3 identity solution.
