Huoxun Finance reports that Circle's institutional-grade blockchain, Arc, has released a phased upgrade roadmap for post-quantum cryptography (PQ). The plan is to introduce a post-quantum signature scheme upon mainnet launch and gradually cover the entire stack, including private state protection, infrastructure hardening, and validator authentication. The Arc mainnet will support post-quantum signatures from launch, employing an opt-in mechanism that eliminates the need for forced migration or a network-wide reset. Users can create wallets with long-term security. The near-term goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private recipients. Public keys will be additionally encapsulated with a symmetric encryption layer in privacy mode. The medium-term plan is to upgrade the infrastructure layer, aligning with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSMs). The long-term goal is to complete validator signature hardening—given Arc's final block confirmation time of less than one second, current assessments suggest that the risk of quantum attacks at this stage is relatively limited, and this will be steadily advanced once the post-quantum consensus toolchain matures. Circle also warned that attackers may employ a "collect now, decrypt later" strategy, and organizations should plan their cryptographic migration paths as early as possible.
