We now support verifying FEP-8b32 Object Integrity Proofs using either eddsa-jcs-2022 or mldsa44-jcs-2024.

The latest version of Mastodon can verify FEP-8b32 integrity proofs, which replace outdated Linked Data Signatures.

The Fediverse server applications that are the farthest from Mastodon while still largely being capable of the same things as Mastodon. Mastodon's nemeses, so-to-speak. The stuff created by the guy who speaks out the most radically against what Mastodon does.

But now there seems to be a change in attitude

If they do it first subsequent implementations don't deserve recognition?

FEP-8b32 mentions post-quantum sigs in the "Future work" section, but I don't want to RECOMMEND anything yet because Quantum-Resistant Cryptosuites v1.0 is a Working Draft.

using either eddsa-jcs-2022 or mldsa44-jcs-2024

Is this the first implementation of a post-quantum scheme?

Right now eddsa-jcs-2022 is "RECOMMENDED" by FEP-8b32. Should ML-DSA be "RECOMMENDED" too?]]>https://forum.pierobosio.it/post/https://zotum.net/item/375aecbd-f256-445e-a5eb-174e0802ea80https://forum.pierobosio.it/post/https://zotum.net/item/375aecbd-f256-445e-a5eb-174e0802ea80Sat, 22 Aug 2026 08:56:52 GMT<![CDATA[Reply to Say goodbye to Linked Data Signatures on Sat, 22 Aug 2026 06:28:08 GMT]]>@silverpill Mastodon implements something that's already implemented in Hubzilla, (streams) and Forte. Incredible.
