You are right Murch, I didn’t fully understand the issue with each signature being one time only. I have now made a proper revision to my proposal to fix this issue. Each address now commits to a Merkle Key Tree, giving users 64 attempts at signing. The proposal website and github repository have been updated with this change. Is this a wide enough safety margin? Does this properly address your concern? Tell me where else I am wrong and I will try to fix it! I deeply appreciate your continued feedback on my idea!
