When deploying fabric in enterprise's intranet (without the ability to access internet), users maybe upload chaincode builder images and chaincode runtime images to a private docker registry which requires authentication when pulling images.
I think fabric can support this scenario by adding configuration in chaincode section of core.yaml, such as:

chaincode:
    registry:
        

Our versioned containers implement into_v1, as_v1, as_mut_v1 separately. To make this look more rusty I propose:

• find all instances of into_v1 in the code and replace them with implementation of From trait
• find all instances of as_v1 in the code and replace them with implementation of AsRef trait
• find all instances of as_mut_v1 in the code and replace them with implement

Please update the DID Resolver within ACA-Py for "did:sov" to follow the rules as recently updated in the DID Method spec. This means adjusting the returned DIDDoc to exactly what is documented in the DID Method spec for the cases of their being no endpoint ATTRIB, a "current convention" endpoint ATTRIB and support for the defined new convention endpoint ATTRIB.
