Coinbase CEO Brian Armstrong sought to allay concerns about the impact of quantum computing on blockchain security, stating that the industry is already coordinating on long-term solutions to safeguard digital assets. Armstrong explained that Coinbase maintains active dialogue with major blockchain networks about transitioning toward post-quantum cryptography, and the company has formed an advisory board to evaluate technological progress and provide guidance to the industry.

Why it matters

The potential threat of quantum computing to the security of blockchain networks has been a growing concern in the crypto industry. Armstrong's comments aim to reassure investors that the industry is proactively addressing this issue, which could otherwise deter institutional capital from entering the market.

The details

Armstrong stated that practical quantum threats remain years away, giving the industry sufficient time to coordinate defensive upgrades. He noted that Coinbase continues to monitor academic and private-sector quantum research, and the company's advisory board will respond quickly if credible threats appear. However, some industry figures, such as Ethereum co-founder Vitalik Buterin and investor Kevin O'Leary, have voiced caution about the potential impact of quantum computing on crypto.

  • Coinbase recently formed an advisory board focused on quantum computing research.
