Once voiced in #trilema and rated such that you are a member of deedbot's L1-L2, you may submit ascii-armored clearsigned GPG messages to deedbot thus.
!!deed http://dpaste.com/message.txt
If the submitted message has a valid signature from a member of L1-L2, it is accepted for inclusion in the next hourly bundle. At the hour, all submitted messages are joined with a single newline; the result is hashed with sha256. The hash is used as a Bitcoin private key, and a small amount of Bitcoin is sent to the corresponding address.
