Summary

We need to create and record records on the blockchain to help audit the various artefacts we produce during a fund, starting with F12.

JIRA Epic

https://input-output.atlassian.net/browse/NPG-????

Description

The main artifacts we need to capture are:

• All the event start artifacts:
  • Block 0
  • Snapshot
  • Final proposals lists/reviews/etc
  • Other stuff?
• Running audit entries
  • 1 record per blockchain archive (1 per hour) during F12.
• Final Artifacts
  • Results
  • Anything else?

The metadata on chain needs to capture:

• name of the fund
• name of the artifact
• hash of the artifact
• link to the artifact

We can store this as an array so we can put multiple entries in a single transaction (as required).

Todo

• [x] #682
• [x] #683
• [x] #684
• [x] Integrate the tool with Artifact generation and Jormungandr blockchain snapshots.
• [ ] Document what the community should look for on-chain if they want to independently validate these artifacts.
• [ ] ~~Create a public catalyst-artifacts repo to hold the public artifacts we otherwise would have stored in the private catalyst-artifacts repo so we can link to it from metadata.~~ We are storing the artifacts on ipfs
• [x] test it all works as expected during dry-runs using the pre-prod network.
• [ ] Verify that its possible to hash a sub-section of the final voting blockchain equal in size to a previous snapshot, and the hashes match. If they do not match identify why.

Suggested Metadata: Use CIP-20

{
  "674":
         {
           "msg":
                  [
                    "Catalyst Audit Data",
                    "fund-name: fund 1234",
                    "artifact: Fund Parameters",
                    "hash: 0x1234...abcd",
                    "link: https://www.somewhere.io/something/something/FundParameters.zip"
                  ]
