Satoshi Signed PGP, or GTFO.
Did Satoshi ever sign anything with his PGP key? I heard he never signed anything, and someone said it's useless unless he did. However, I don't understand PGP too well. Did Satoshi ever post his public PGP key anywhere?
I know he could sign a message from an early Bitcoin address if his PGP key is useless, but I'm curious whether it is or not.
Yes, he would need to sign a message from a few (more than one, the better, to prove the signer isn't just an early miner)
of his early mining bitcoin addresses. That would be very possible.
In relation to his PGP Key, many have said he had no such key, but there is this record according to bitcoin.org github:
https://github.com/bitcoin-dot-org/bitcoin.org/commit/19e0c74df2162d4510db5df9e50d5ac53b38c498.
An alternative would be to have him sign a message with an address in the coinbase transactions in any of the first couple of blocks.
