The quantum era is kicking off earlier than expected, and many people still haven’t understood this track. On April 6, Circle’s institution-grade blockchain Arc was officially announced, along with the roadmap for upgrading quantum cryptography. Simply put: they’re already preparing for the day when “quantum computing breaks encryption.” Once the Arc mainnet goes live, it will support post-quantum signatures, with optional access—no forced migration—so users can create wallets with longer-term security on their own.

Next, they’ll extend this “anti-quantum capability” even deeper: including private transactions, hidden balances, and even recipient information will be further protected. In the medium term, they will upgrade the underlying security to align with industry standards like TLS 1.3, strengthening everything from access control to cloud environments to hardware security. As for validation nodes, since block confirmation is less than 1 second, the current risk isn’t high, but in the future they will also be upgraded step by step.

More importantly, Circle has made it clear that—some people may be “collecting data now to decrypt it with quantum computing in the future.” Most people are still watching prices, while a few have already started looking at “security 10 years from now.”#Gate广场四月发帖挑战 #国际油价走高 $MMT $TRU $OPEN
