Overview
- Project Eleven completed a quantum threat assessment of Solana’s wallets, validators, signature assumptions, and long‑range risks, then deployed a testnet processing end‑to‑end transactions secured by post‑quantum signatures.
- This is a prototype rather than a mainnet change, with work now focused on migration paths, algorithm selection aligned with NIST standards, and block‑space and verification trade‑offs; it also builds on Solana’s opt‑in Winternitz Vault wallet feature.
- Coverage describes Solana’s live test as ahead of most major chains still using classical signatures, including Bitcoin and Ethereum, which have not shown comparable production‑style PQ flows.
- In parallel, Aptos proposed AIP‑137 to offer optional SLH‑DSA accounts while keeping Ed25519 as the default, signaling an industry move toward opt‑in post‑quantum protections.
- Views on urgency diverge, with Michael Saylor asserting Bitcoin can harden through upgrades, Adam Back calling near‑term risk decades away, and Charles Edwards warning of material probabilities by 2028–2030.
