After a sharp decline in the U.S. stock market in the first quarter, a rebound followed, with geopolitics and interest rates dominating the market trend. Wall Street is currently divided between bullish and bearish views, and April may be the decisive month...

ChainCatcher News, according to the official blog, Arc, the institution-level blockchain under Circle, has released a phased roadmap for post-quantum cryptography (PQ) upgrades. It plans to introduce post-quantum signature schemes when the mainnet launches, and gradually extend PQ protection to private state security, infrastructure hardening, and validator authentication across the full-stack. Arc's mainnet will support post-quantum signatures from launch, adopting an opt-in mechanism that does not require forced migration or a network-wide reset. Users can independently create wallets with long-term security. The short-term goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private recipients. In privacy mode, public keys will have an additional symmetric encryption layer encapsulation. The mid-term plan is to advance infrastructure layer upgrades, align with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSM). The long-term goal is to complete validator signature hardening. Given that Arc's block finality time is less than one second, current assessments deem the risk of quantum attacks in this stage relatively limited, and validator upgrades will proceed steadily as the post-quantum consensus toolchain matures. Circle also warns that attackers may use a "collect now, decrypt later" strategy, and institutions should plan cryptographic migration paths as early as possible.
