Did:orb

Full Title

Description of the did:orb method implementation.

Context

still working on the implementation. I can let you know once we have the basics ready.

• make targets that produce the binary (make orb) and the docker image (make orb-docker).
• snapshot docker images here: https://github.com/orgs/trustbloc-cicd/packages/container/package/orb
• Once there is a release, there will be release images here: https://github.com/orgs/trustbloc/packages/container/package/orb (currently 404 due to no releases).
• This project serves as a incentive to assure that did methods can be testably secure and is tracked in the wiki page Open Source Security.

The Implementation

Troy Ronda (SecureKey) 2021-05-04

In other news, we also pushed the first pre-release 0.1 version of vct and orb. It’s still early days - this is really a pre-release focused on early integration.

• We are also running devel domains to play with it (to be cleared):
• Sidetree endpoint discovery: https://orb-2.devel.trustbloc.dev/.well-known/did-orb

{"resolutionEndpoint":"https://orb-2.devel.trustbloc.dev/sidetree/v1/identifiers",
"operationEndpoint":"https://orb-2.devel.trustbloc.dev/sidetree/v1/operations"}

• Webfinger endpoint example: https://orb-1.devel.trustbloc.dev/.well-known/webfinger?resource=https%3A%2F%2Forb-1.devel.trustbloc.dev%2Fsidetree%2Fv1%2Fidentifiers

{"subject":"https://orb-1.devel.trustbloc.dev/sidetree/v1/identifiers",
"properties":{"https://trustbloc.dev/ns/min-resolvers":1},
"links":[{"rel":"self","href":"https://orb-1.devel.trustbloc.dev/sidetree/v1/identifiers"}]}

• Sidetree + ActivityPub example: https://orb-1.devel.trustbloc.dev/services/orb/outbox?page=true
• CAS example: https://orb-1.devel.trustbloc.dev/cas/Qmesb9uoKxsunwugVBrWrm9Lg6SkzQWEa7SMZTBxDxCsqF
• Resolution example: https://orb-1.devel.trustbloc.dev/sidetree/v1/identifiers/did:orb:EiAfjRj4_Wo2tyQBsoeOEH1FHd481iwGnwbcAM_DeqZEoQ (still need to add network prefixing).
• VCT signed tree head example: https://vct-1.devel.trustbloc.dev/ct/v1/get-entries?start=0&end=10
• VCT entries example: https://vct-1.devel.trustbloc.dev/ct/v1/get-sth

We’ll soon bring up a third dev domain so we can start seeing announcements.

Did not run because go version files.

• Remove all GO and reinstall 1.16.3

then add these to ~/.profile

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

• Makefile is using abspath in call to frapsoft/openssl with is two unacknowledged dependencies in did:orb code.

Software Bill of Materials

In response to Executive Order on Cybersecurity these are the components that were required to build the product. It is not clear which parts actually provide code to the finished product, but they all contributed to the building of the finished product. Where finished product includes the certificates and other support files.

• Ubuntu 20.04
• sudo apt update - on 21-05-13 this installed 20 updates just in the past one month including many library as well as paython3
• GoLang 1.16.3
• frapsoft/openssl
• Docker
• Docker-compose (both from docker-desktop)
• mysql:8.0.24
