Inspired by @pds.dad@bsky.brid.gy 's AMA about #atproto over on #Mastodon ... AMA about #ActivityPub and the #Fediverse! No question is too basic! (If questions get beyond my knowledge I'll at least try to point you in the right direction 😃)
Is there a signing layer in AP like how we have with our signing keys in the did doc to know if a record/post actually came from that user?
