Coinbase warns Bitcoin quantum security upgrades could take years, urging early developer preparation.

Coinbase has issued a technical paper urging Bitcoin developers to start preparing for future quantum computing threats, which could compromise Bitcoin's current cryptographic security. The company, holding about 5% of all Bitcoin, highlights that transitioning to quantum-resistant security could take several years and involves complex changes beyond just new signature algorithms. Coinbase recommends flexible transaction designs like BIP-360 and hybrid wallets that support both current and future quantum-resistant signatures, while also calling for separate discussions on handling dormant or lost Bitcoin. The company emphasizes early preparation to protect Bitcoin before quantum computers capable of breaking existing cryptography become practical.

The story on Coinbase's proposals to protect Bitcoin from quantum risks is presented with Pluang's market data for context. For readers following the broader cryptocurrency market, 32 of 50 major cryptocurrencies rose while 17 fell as of Oct 14, 2026 11:41 WIB.
