Sorry, didn’t see this question.

Essentially, PGP allows us to establish decentralized identities… many in the Monero / security / privacy space have verified my key in person, at conferences, etc. Using the message above, they can establish that this is not an impostor account (unless I was sloppy and lost access to my PGP private key). For those who don’t know me personally, they can still establish that the same key that signed that message above also made the following code changes to Monero stretching back to 2017. The key has also been verified and digitally signed by some members of the Monero Core team who you may trust to some degree. You still decide, but you have a bit more info now.

Hope that helps.
