We also intend for project Aries to support multiple DID methods through a generic resolver interface. This generic interface will initially support the Hyperledger Indy resolver but will be extensible so that if someone wanted to build a pluggable Hyperledger Fabric DID method resolver, Ethereum DID method resolver, or another DID method resolver in they could. These resolvers would support the resolving retrieval of transactions and other immutable data that has a shared state on a ledger. One of the other pieces that will come built into this project will be support for a peer DID method resolver which will rely upon the wallet and p2p messaging protocol to maintain the state of a peer-to-peer relationship. Another interaction that the resolver interface will support is the ability to resolve data that exists in a verifiable data registry. An example of a VDR is the Indy Catalyst project.
