The Bitcoin community is grappling with a complex issue: what to do about the millions of coins that could be vulnerable to a future quantum attack. A Coinbase advisory council of leading cryptographers has weighed in, urging the community to start technical planning for post-quantum signatures now, despite the fact that quantum computers are not yet a threat to Bitcoin. The council's report highlights the exposure of approximately 6.7 million Bitcoin, including 1.7 million in early addresses likely tied to Satoshi Nakamoto and lost keys, fueling a debate over whether to let these coins remain spendable. The council declines to choose between proposals that could freeze or constrain vulnerable coins, instead emphasizing the need for compatible solutions and clear communication from the Bitcoin community. This raises a deeper question: how should the Bitcoin community approach the challenge of protecting its network from a potential quantum threat, and what implications will this have for the future of Bitcoin and its users?
