Quantum Registry Rates Bitcoin Transactions “Vulnerable”. Where Do New Layer-1s Stand?

Quantum computers cannot break Bitcoin today. On that, almost everyone agrees. The heated debate is about timing, and about how long a fix would take once one is needed. A new public registry gives that argument some structure. The Quantum Alliance, an open standards body launched on October 15 and 16 by nine blockchain organizations , has rated 177 chains on how ready their signatures are for a quantum attacker. The results are a useful map of who has work to do. Each chain gets two grades, one for consensus and one for transactions.
