Short: fwupd users download small but in total too much metadata over the internet.
A solution for local distribution is needed. IPFS is too slow, Bittorrent is immediately suspicious on many Networks.
Passim is a new protocol for this purpose, users can opt out, it is secure and the metadata is hashed, and the hashes still downloaded over the internet for verification.
