Bitcoin BIP: Post-Quantum Migration and Legacy Sunset
Casa co-founder Jameson Lopp, Christian Papathanasiou and other cryptographers for July 14, dem publish one draft Bitcoin Improvement Proposal (BIP) wey dem call “Post-Quantum Migration and Legacy Signature Sunset” for GitHub. The plan dey use the new P2QRH output type and e dey roll out for three phases: Phase A (three years after activation) no allow make dem fund quantum-vulnerable addresses; Phase B (two years later) no accept ECDSA and Schnorr transactions, make legacy outputs freeze; Phase C dey find way recover funds using zero-knowledge proofs. McKinsey talk say threat-level quantum computer fit show between 2027–2030, and about 25–30% BTC (around five million coins, including exposed Satoshi addresses) dey at risk. By no allowing transactions go vulnerable addresses, the BIP dey force migration to quantum-secure scripts. E wan stop delay wey dey among wallets, exchanges and custodians for upgrading. If dem adopt am, dis migration go pass SegWit and Taproot for scale, and e go make Bitcoin long-term security strong against quantum threats.
Neutral
Dis BIP dey tackle one big long term threat to Bitcoin wey dey come from quantum computing by show how to move step by step to post-quantum signature schemes. For short time, e no go too affect trading because activation go still take years and migration go happen in phases. For long term, to use quantum-safe scripts fit make network security and investor confidence strong, and dat good for Bitcoin market stability. But the wahala and coordination wey e need fit slow down how people go take adopt am, so e no go too affect price quickly. All in all, dis news dey support Bitcoin resilience without causing big market moves, so im impact na neutral.
