Squads tests post-quantum signing on Solana mainnet as security debate intensifies
Summary
Squads, Solana's leading multisig protocol, has successfully tested post-quantum signing using Falcon-512 for its multisig voting members on the Solana mainnet, a development announced by cofounder Sean Ganser on October 13. This milestone is particularly significant amidst growing concerns about the security of cryptographic systems against potential advances in quantum computing, prompting Solana cofounder Anatoly Yakovenko to encourage developers to adopt post-quantum cryptography. Squads' innovative approach allows the combination of traditional Ed25519 signatures with Falcon-512, enhancing security by ensuring that the compromise of one signature scheme does not automatically jeopardize the entire approval process.

Analysis
Solana: Solana is a high-performance blockchain platform that supports smart contracts and decentralized applications. Squads conducted its post-quantum signing test on Solana mainnet, leveraging the chain’s existing Ed25519 signatures while introducing alternative schemes via offchain verification. Solana cofounder Anatoly Yakovenko has urged wallet developers to prepare for post-quantum cryptography. Squads: Squads is Solana’s leading multisig protocol that manages permissions, proposals, approvals, and transaction execution through its onchain program and account abstraction model. It recently tested Falcon-512 post-quantum signatures for voting members on Solana mainnet, with plans to add support in the next SquadsX browser extension release. Cofounder Sean Ganser announced the milestone amid rising discussions on cryptographic security. Sean Ganser: Sean Ganser is cofounder of Squads, the multisig protocol on Solana. He announced the successful mainnet test of Falcon-512 post-quantum signatures for multisig voting on October 13. Ganser highlighted plans to integrate the feature into the SquadsX extension. Justin Drake: Justin Drake is a researcher at the Ethereum Foundation. He has urged the crypto industry to adopt defensive measures against possible breakthroughs in AI-driven mathematics that could compromise existing cryptographic systems. Drake’s warnings contributed to the broader debate prompting Squads’ post-quantum testing on Solana. Anatoly Yakovenko: Anatoly Yakovenko is cofounder of Solana. On October 8 he called on wallet developers to implement post-quantum cryptography and improve key management processes. His comments followed warnings from Ethereum Foundation researcher Justin Drake about potential AI-driven threats to cryptography. Cryptographic Diversity: Multisig setups can combine different signature schemes, such as Falcon-512 and Ed25519, so that compromising one does not automatically expose the entire approval threshold. Solana Security Guidance: Solana cofounder Anatoly Yakovenko recently urged developers to begin implementing post-quantum cryptography and establish reliable key rotation processes. Post-Quantum Cryptography: Falcon is a lattice-based signature scheme submitted to NIST’s Post-Quantum Cryptography project and designed to resist quantum computer attacks.
