Coinbase launches plan for quantum-resistant Bitcoin

Coinbase, the major U.S. cryptocurrency exchange, has launched a multi-year initiative to prepare Bitcoin and the broader blockchain ecosystem for the future threat of quantum computing. The company announced on July 23 that while a quantum computer capable of breaking current cryptographic security is not an immediate danger, the industry must begin coordinated preparations now due to the immense complexity of upgrading decentralized networks.

The company’s chief information security officer, Jeff Lunglhofer, stated in a blog post that a fault-tolerant quantum computer capable of defeating the elliptic curve cryptography securing Bitcoin and other major blockchains will eventually be built, though the timeline remains uncertain. He emphasized that the migration of millions of users and decentralized systems to new cryptographic standards could take years, making early planning essential.

Coinbase’s strategy focuses on three core areas: upgrading its own custody infrastructure, ensuring compatibility with emerging post-quantum standards across blockchains, and fostering industry-wide collaboration. The company is developing PQCoreKMS, a post-quantum version of its proprietary...
