I'm working on !boinc@sopuli.xyz and !gridcoin@lemmy.ml . BOINC is a tool used by scientists to distribute computational workloads to the computers of volunteers, Gridcoin is a cryptocurrency which issues rewards for people who use BOINC (like mining crypto but for science instead of hashes). I'm not a direct dev on either project, but I code tools which make those projects easier to use, write documentation, etc.
