That earlier BIP introduced a soft fork creating a new output type called \u003Cstrong>pay-to-Merkle-root (P2MR)\u003C/strong> — essentially a Taproot-style construction without the quantum-vulnerable “key path.” While BIP-360 protects all newly created coins, it leaves the existing 34 % of supply exposed.

Roadmaps from McKinsey and several academic groups referenced in the BIP point to the possible arrival of cryptographically relevant quantum computers between \u003Cstrong>2027 and 2030\u003C/strong>. Google has already publicly committed to completing its own migration to post-quantum cryptography by 2029.
