Coinbase CEO Brian Armstrong said quantum computing will not “break the blockchain,” calling it a solvable issue. He revealed the exchange has formed a quantum advisory board and is working with major networks on cryptographic upgrades. Armstrong also addressed U.S. market-structure talks, defending Coinbase’s stance on legislation and backing CFTC authority over prediction markets.
Coinbase CEO Brian Armstrong stated that quantum computing will not destroy blockchain technology. “No, that’s not true,” Armstrong said in an interview, adding “I think that’s a very solvable issue.”
He noted the company has been proactive, forming a quantum advisory council last month. The board includes experts like University of Texas professor Scott Aaronson and Stanford cryptographer Dan Boneh.
The group is expected to publish research on quantum risks and migration strategies. Independent director Pranav Agarwal noted the primary risk is quantum computers breaking the private keys of SHA-256 encryption.
Agarwal stated there is enough time to upgrade encryption standards for major networks. Across the industry, the Ethereum Foundation has made post-quantum security a top priority.
Solana Foundation has begun testing quantum-resistant signatures on a testnet. Bitcoin developers have also advanced proposals like BIP 360 to reduce quantum-exposed key paths.
Armstrong also discussed ongoing U.S. market-structure legislation talks. He addressed Coinbase’s opposition to a previous draft of the bill, known as the CLARITY Act.
Armstrong pushed back on claims Coinbase “blocked” the legislation, saying its concerns brought lawmakers back to the table. He expressed confidence a compromise could move forward in the coming months.
The CEO also backed the Commodity Futures Trading Commission‘s authority over event contracts. He addressed debates around stablecoin rewards during the market-structure discussions.
