1) Not all signatures are on chain. All that is needed is to post the signature somewhere and verify it with the message and public key.
2) Whoever has the private key can produce the signature, and the signature can only be produced by someone who has the private key (assuming the cryptography is secure)
- cmatthias 4y agoI realize not all signatures are on the chain, that’s obvious if you know what a signature is. That’s why I’m asking whether it appears on the chain. :) If it appears somewhere associated with that transaction, that’s pretty strong evidence that Shkreli is correct. If it does not appear on chain at all, then Shkreli is wrong and his post proves nothing about the identity of Satoshi.
