Coinbase's newly formed Cryptography Advisory Board believes that quantum computers do not currently pose an immediate threat to blockchain, but the Bitcoin community should start planning for post-quantum signature migration. Reports suggest that approximately 6.7 million BTC could be at risk of future quantum attacks, with around 1.7 million BTC located in early addresses, many of which are believed to be associated with Satoshi Nakamoto or lost private keys. The current debate centers on whether vulnerable assets in addresses that haven't migrated to quantum-resistant signatures should be frozen or restricted in the future. However, the board declined to recommend a single best solution, stating that such decisions should be made by the Bitcoin community, though preparations for the technical migration to post-quantum signatures should begin as soon as possible.
