Aptos introduces post-quantum signatures before they’re urgently needed

Aptos has proposed an optional post-quantum signature scheme, citing long-term risks that advances in quantum computing could pose to existing cryptography.

Blockchain network Aptos is moving toward a post-quantum signature option, reflecting growing concern that advances in quantum computing are no longer purely theoretical and could eventually affect how blockchain networks secure accounts and transactions.

On Thursday, Aptos outlined a proposal to introduce post-quantum signatures, addressing the network’s reliance on digital signatures for ownership, transaction authorization and overall security. 

While existing cryptographic schemes remain secure against classical computers, researchers warn that sufficiently powerful quantum machines could one day forge them, potentially compromising account security retroactively.
