Bitcoin faces bigger quantum risk in transit, not wallet keys

A venture capitalist who has spent a decade backing deep-tech and quantum hardware startups warns that the Bitcoin industry is focused on the wrong half of the quantum threat: wallet keys instead of encrypted messages already moving between exchanges, bridges and custodians.

Andrew Gault, CEO of networking firm ZeroTier, told CoinDesk that the financial system's most dangerous vulnerability is not stored data but data moving between institutions right now. "Every interbank message, every payment authentication record, and every digital signature traveling across a network today is being collected by sophisticated adversaries who don't need to re," he said. The implication for crypto traders is that even if wallet keys are secured, the underlying transaction infrastructure could be compromised once quantum computers mature enough to break current encryption standards. Live crypto prices and charts on NowPrice show how the market is reacting to this emerging risk narrative.

Looking ahead, the industry must accelerate the adoption of quantum-resistant cryptographic algorithms for network communications, not just for wallet key generation. Traders should monitor developments in post-quantum cryptography standards and any announcements from major exchanges or custodians regarding upgrades to their transport layer security. The timeline for a practical quantum threat remains uncertain, but the data collection is happening now.
