Sui is adding two NIST-approved post-quantum signature schemes, so accounts can move to quantum-safe keys derived from the recovery phrase users already hold.
Sui, where money moves as freely as messages, announced today that it is adopting two post-quantum signature schemes in its move toward quantum readiness.
The quantum timeline is different for blockchains, because a public key onchain is different from a public key anywhere else. In most systems, an attacker needs a breach before they can start working on a key. Onchain, the key is already published, exposed permanently the moment an account transacts.
