BitGo flags Bitcoin transaction signatures as primary quantum computing risk
Bitget2026/10/29 21:24- Quantum computing poses a greater future threat to Bitcoin transaction signatures than mining, according to BitGo's analysis.
- More than 34% of bitcoin had public keys exposed onchain as of March 1, 2026, according to BIP-361 estimates.
- No publicly known quantum computer can recover Bitcoin private keys from public keys today.
- Holders can reduce exposure through wallet management, but protection against fast quantum attacks would require protocol changes.
- Proposed Bitcoin upgrades remain drafts, leaving migration paths and the treatment of vulnerable dormant coins unresolved.
