SRI - CCSM integration discussion

[biscuitdey]

Overview

This issue tackles as conditions and controls regarding deploying and calling the ccsm contract functions.

Tasks

• [ ] Discuss who and when should deploy the contract
• [ ] Allow only owner to add anchor hash to the ccsm contract

[ognjenkurtic]

Latest agreement is as follows:

• There is one smart contract per BPI used to store all anchor hashes across all workgroups that are active in it

• Smart contract owner is an account controlled by the BPI

• Smart contract contains a map of workgroup id -> content addressable hash array and a pair is created each time there is a new workgroup created

• content addressable hash array contains the list of all of the transactions hashes, where tx hash is txResult.hash = hashFn(${merkelizedInvoiceRoot}${witnessHash}).toString('hex'); and is updated after each successful execution of a workstep (succesfull state change) for a given workgroup

• It is the responsibility of the account in control of the BPI to trigger the smart contract methods after events

We need a following list of issues to be implemented for this mechanism to work:

• implement the smart contract with the needed functionalities (add workgroup, add CAH...) #797
• Enable BPI to store relevant information to communicate with the smart contract (private key, address ...) #803
• trigger add workgroup onchain on workgroup creation in the BPI
• trigger add CAH on succesfull workstep execution #805
• implement an endpoint to fetch StateTreeLeafValueContent object with accompanying info based on the provided CAH #806
