Quantum computing fit break Bitcoin signatures and shift mining — Coinbase analyst dey warn
David Duong wey dey lead research for Coinbase warn say quantum computing get two different gbege for Bitcoin: (1) signature wahala — Shor algorithm fit find private keys from public keys wey don show, make person fit knack money from addresses wey dey show public keys (specially ones wey dem dey reuse or old P2PK/P2PKH formats); and (2) quantum mining advantage — Grover-style speedup or future quantum miners fit make proof-of-work fast, give miners wey get quantum gear big advantage and fit make mining centralised or fit lead to 51% attack. On-chain analysis show say about one-third of BTC supply (~6.51 million BTC) dey for address types wey don expose public keys or get higher structural risk if owners no move their funds. Current quantum hardware never reach level to do practical attacks yet, but timelines different: some experts talk say e go take decades, others dey warn say action fit need within few years. Mitigations include immediate operational steps for users (no reuse address; move funds from legacy addresses when e safe), infrastructure changes by exchanges and custodians, plus protocol-level adoption of post-quantum signature schemes (NIST don pick candidate standards). Big migration fit happen but e complex and fit take about 2–7 years for wallets and custodial services to fully adopt post-quantum signing. Traders suppose dey watch wallet migration activity, big on-chain movements from legacy addresses, exchange security disclosures, and any protocol proposals or soft-fork plans for post-quantum upgrades — these signals go affect how people see custodial risk and fit change confidence for BTC market.
Neutral
Di tok news dey bring serious security and structural yawa for Bitcoin but e no mean say price go crash sharply now. Signature wahala (addresses wey dey show public keys) na operational risk we fit make people move funds on-chain as precaution and sell small when big legacy balances dem migrate; dem kinds flows fit cause short-term selling pressure or volatility. But quantum-capable attacks no yet practical, and mitigation ways dey (address migration, post-quantum signatures), so long-term basic demand for BTC no too likely to scatter. Protocol-level changes and big migrations go take years and need coordination; if dem announce concrete upgrade plans or big custodial migrations e fit trigger short-term market reactions. Overall, expect episodic volatility tied to migration events and security disclosures, but no clear long-term bearish outcome for BTC unless real, near-term quantum attack capability show face.
