The challenge is to build a flow that protects both content and metadata, works both online and offline, and is redundant across multiple relays / blossom servers

We have released an MVP but the logic is tied to sigit.io

We are close to the next release in which the logic is encapsulated in state machines and will work seamlessly across clients (encryption, OTS, retries, support for various mark types in pdfs, template agreements, etc)
