These RFCs capture abstractions, models, protocols and data formats for facilitating cross-ledger communication and transactions.
If you are new to Weaver (or to blockchain interoperability), we recommend starting with the protocol overview document.
If you wish to see Weaver in action, test it, or apply it to your own application, you can switch to the Getting Started Tutorial.
Instead, if you wish to find out more details about the Weaver design and wish to contribute to the code base, you can explore these RFCs, beginning with the models. Protocol engineers will find in RFC: 01-009 a useful overview of the relay model, and may then progress on to reading one of the existing protocols' design and implementation; e.g., the data sharing protocol in RFC: 02-001. If you are interested in adding support for a new ledger technology, see the existing driver implementations and existing interoperability module implementations. Where relevant we use ABNF for formal syntax definitions.
Precise definitions of terms you may encounter in these RFCs can be found in the terminology page.
The RFC numbering convention is: <type>:<id>. The list of types (<type>) is as follows:
