<![CDATA[Hey, Free and Open Source Software developers!]]>Hey, Free and Open Source Software developers! Do you want $5000 for making a library in your favourite programming language?

@Interledger is offering grants of up to $5000 for implementations of RFC 9421, "HTTP Message Signatures".

https://interledger.org/grant/open-payments-sdk

RFC 9421 is the essential authentication system for 's federation protocol. Robust, secure and reusable libraries make it easier to build AP into more software and get more people on the Fediverse.

Please take a look!

Yes, Fediverse servers often use an old version, draft-cavage-12. But a lot of the big and new implementations implement both, including Mastodon. I think in the next year or so, it'd be possible to support only RFC 9421.

I've been reading up on this, and it appears that ActivityPub, and perhaps more to the point, Mastodon, use an older version of the spec than that in the RFC.

Would it be desireable therefore to include a fallback to the older version?

I have received grants from ILF and can confirm they are legit.
