最新报道:Ethereum's Layer 2 network Arbitrum announced a major upgrade to its Nova chain, introducing permissionless validation to enhance decentralization. The upgrade, scheduled for March 14, will allow any user to run a validator node without approval, marking a shift from the current whitelist system. Offchain Labs emphasized this change aims to improve network security and transparency while maintaining compatibility with existing applications. The Arbitrum DAO will oversee future protocol decisions following the transition. Nova currently processes over 200,000 daily transactions, serving gaming and social applications with lower fees than Ethereum mainnet.
