Briefings

Coinbase CEO Brian Armstrong stated quantum computing poses a greater long-term threat to cryptocurrency security than AI, urging industry-wide adoption of quantum-resistant security measures. Google researchers modeled a future quantum attack capable of recovering a private key in approximately nine minutes under specific hardware assumptions, following advance preparation. Coinbase is upgrading its custody infrastructure and has formed an independent advisory board to assess scientific developments and provide guidance to the industry on preparing for future security risks.

Key points

• Coinbase CEO Brian Armstrong explicitly stated that quantum computing poses a greater long-term threat to cryptocurrency security than artificial intelligence, calling for preparations against future attacks.
• Google researchers modeled a future quantum attack that could recover a private key in about nine minutes under specific hardware assumptions, following advance preparation.

Context

Coinbase Global Inc. CEO Brian Armstrong weighed in during an earnings call, distinguishing between AI finding new ways to defeat existing cryptography and quantum computers performing calculations that could undermine it. The company is upgrading its custody infrastructure and has formed an independent advisory board on quantum computing and blockchain in January to assess scientific developments and provide guidance to the industry on preparing for future security risks.

Limitations

Evidence is limited to a single earnings call transcript and a single research model; no independent verification of the nine-minute attack timeline or the specific hardware assumptions used by Google researchers is provided.
