We ran out of time to discuss these yesterday. These are the drafts: https://www.ietf.org/archive/id/draft-hallambaker-dare-00.html https://www.ietf.org/archive/id/draft-hallambaker-earl-01.html
The immediate application for these drafts is to support exchange and update of JSContact cards. But they are both intended to support a wide range of applications and have been applied in experimental contexts over a period of over ten years. The approach taken is designed to support very general applications but I have focused on the essential parts in these drafts. The DARE architecture is designed to allow envelopes to be specified in COSE, XMLDigSig, even ASN.1 if you want but lets start with just JOSE. The sequence scheme is designed to support incremental signature (aka blockchain) and encryption and I use this in my systems. But while incremental encryption is a nice constrained problem that doesn't have masses of profitable variations, there are many ways to do Merkle signatures and so I have left those out entirely. Although originally designed to support uses in the Mathematical Mesh, these drafts describe versions with multiple breaking changes. These are to align the specifications with work in QUIC and MOQ.
