According to @caprioleio, Bitcoin must be upgraded to be quantum-proof by 2026, with a warning of severe consequences if no upgrade occurs.

Source: https://twitter.com/caprioleio/status/1972473521730462153 Bitcoin’s current signatures use ECDSA and Schnorr (BIP340) over secp256k1, both based on the discrete logarithm problem that Shor’s algorithm would break on a sufficiently large fault-tolerant quantum computer, underscoring why post-quantum migration is being standardized globally.
