> @mvid: I work in crypto, and even I ask, what makes this better than GPG?

OP: two points.

1. It helps harness the help from EVM wallet's adoption. Most people don't know how to use GPG. Most GPG tools aren't built with mind of regular user as target audience.

2. We could soon see on-chain identities, and organizational relationships linked to it. E.g. one could use ERC-1271 to have a contract attest to a signature.
