The largest U.S. crypto trading exchange, Coinbase Global, has issued a warning about the potential threat of a quantum computing system that could crack a Bitcoin transaction in nine minutes. The company, which was founded in 2012, set up an independent advisory board to study the impact of quantum computing on blockchain networks like Bitcoin and ETH. The advisory board, consisting of leading experts from the University of Texas at Austin, has "high confidence" that a sufficiently powerful quantum computer will eventually break the cryptography underlying virtual assets. While Bitcoin’s core infrastructure, such as mining, hash functions, and historical ledger, isn't "meaningfully threatened" by quantum computing, it warns that it could threaten cryptocurrencies at the wallet level, particularly wallets with publicly visible key information. The solution to this issue is implementation, but implementation is the harder part.
