Circle's Arc Blockchain Unveils Post-Quantum Security Roadmap

Circle's Arc blockchain has announced a roadmap for post-quantum security design, aiming to proactively defend against potential threats posed by quantum computing to blockchain technology. According to Foresight News, the roadmap focuses on ensuring end-to-end security for wallets, private states, validators, and infrastructure. The plan includes supporting quantum-resistant wallet signature schemes upon the mainnet launch. In the short term, quantum-resistant private state protection will be implemented through private virtual machines. Over the medium to long term, there will be gradual upgrades to infrastructure and validator signatures. Arc's quantum-resistant design features full-stack coverage and user-selectable options, supporting quantum-resistant wallets and private smart contract state protection. It is also compatible with the Ethereum Virtual Machine (EVM) ecosystem, avoiding the need for large-scale mandatory migrations.
