最新报道:Circle is launching Arc, a new Ethereum-compatible layer-1 blockchain designed for payments, using USDC as gas with sub-second finality. Built on Malachite, a high-performance BFT consensus engine, Arc aims to provide vertical integration for Circle's stablecoin operations. While some argue this could fragment Ethereum's ecosystem, others see it as a natural evolution for dollar-native payments. The chain will initially operate with a closed validator set under Proof-of-Authority. Industry experts debate whether sovereign chains like Arc represent a return to enterprise blockchains or simply optimize for payments efficiency, as stablecoin transaction volumes surge toward potential $1 trillion annual flows by 2030. Circle maintains Ethereum will remain crucial despite Arc's launch.
