The proposed AIP-137 introduces the first post-quantum signature scheme for Aptos.
The proposal does not replace existing signature schemes as it does not mandate migration from the current Ed25519.
Quantum computing is edging ever closer; Bill Gates estimates quantum computers will be functional in five years, while Nvidia’s Jensen Huang gives it a 15-30 year timeline. The rapid advancements have sparked concerns in the crypto community, whose infrastructure relies on cryptography, as we have reported. Aptos is preparing for this future, with the latest improvement proposal outlining the network’s first post-quantum signature upgrade.
Dubbed AIP-137, the proposal introduces the first post-quantum signature scheme for Aptos, prioritizing ease of integration. The network believes that quantum computers could break its existing security models, making the proposed upgrade vital to its long-term survival.
