Aptos Proposes Optional Post-Quantum Signatures (AIP-137)
Aptos has proposed adding an optional post-quantum digital signature capability to its blockchain, citing long-term security risks from future advances in quantum computing. The plan, introduced on Thursday, seeks to provide an additional account-level signature option that could help mitigate potential threats to existing cryptographic methods.
The initiative addresses the network’s dependence on digital signatures for account ownership, transaction authorization, and overall security. While current schemes are considered secure against classical computing, researchers warn that sufficiently powerful quantum computers could eventually forge these signatures, creating the possibility of retroactive account compromises.
Aptos Labs referenced ongoing discussions around quantum scaling by IBM and recent regulatory developments, including the publication of post-quantum cryptography standards by the U.S. National Institute of Standards and Technology (NIST), as context for the proposal.
Developers have submitted AIP-137, an Aptos Improvement Proposal authored by cryptographers at Aptos Labs, to introduce support for post-quantum signatures at the account level. If approved through governance, AIP-137 would add SLH-DSA, a hash-based signature scheme standardized as FIPS 205, as an optional account signature type. With this change, Aptos would be among the earliest production blockchains to natively support post-quantum accounts.
Existing accounts would not be altered by the change. Post-quantum accounts would be opt-in, enabling selective adoption by users.
Industry moves toward quantum resilience
Across the sector, networks are preparing for potential quantum risks even as many researchers assess practical threats as years away. Earlier this month, Solana tested quantum-resistant transactions on a dedicated testnet to evaluate how post-quantum signature schemes could be integrated without disrupting existing accounts.
In the Bitcoin ecosystem, developers, researchers, and fund managers have discussed BIP-360, a proposed Bitcoin Improvement Proposal that would add quantum-resistant signature options. The concept remains at an early stage and continues to be debated.
Other figures, including Adam Back, have downplayed near-term quantum risks, arguing that Bitcoin’s security model relies on digital signature schemes and cryptographic hash functions that are not imminently threatened by practical quantum computers.
