Unless they have already put encrypted messages into the existing blockchain using different algos with such a signed message- Then they could use another signature to prove they signed the message with PGP before PGP was broken.
- lordnacho 11y agoHow about just using www.proofofexistence.com? Of course you might have expected the real Satoshi to have done this before the site came up.
- nly 11y agoNo need to do that. Satoshi has bitcoin in the blockchain already that he or she may have secp256k1 keypairs for. Being able to spend these coins would be proof enough.
