Coinbase proposes ways to protect Bitcoin from quantum risks

Coinbase has urged Bitcoin developers to begin preparing for quantum computing threats, warning in an October 13 technical paper that upgrading the cryptocurrency's security could take several years. Coinbase holds approximately 5% of existing Bitcoin and recommends early preparations against future quantum threats. Bitcoin's transition to quantum resistant security could take several years, according to Coinbase's technical paper. Coinbase identified BIP-360 and P2TRv2 as flexible designs for introducing future quantum resistant signature systems. The company proposed hybrid wallets supporting existing Bitcoin signatures alongside future post quantum authentication methods.
