1. How to create/revole/update DID with aries framework2

Aries -> Resolver -> blockchain network

• 合约开发 add DID contracts bestchains-contracts#4
• resolver 开发

2. develop agent(website)

orb contains everything we need which including:

• Sidetree procotol implementation
• CAS KMS Storage solutions

From orb,we should know how to integrate aries and sidetree together.

Basically it contains two important components:

• orb-server: The implementation of DID solution
• orb-cli : The client tool to interfact with DID service

Orb seems using aries-framework-go and aries-framework-go-ext

Basic Crypto Algorithms

• ED25519

KMS in orb

• local kms https://github.com/hyperledger/aries-framework-go/tree/main/pkg/kms/localkms
• web kms https://trustbloc.readthedocs.io/en/latest/kms/index.html
