[CHECKLIST] Jobs v2 Milestone 2

[shekohex]

Overview

In the first milestone, we did merge #624 that includes the most basic working blocks for the new Services System design. In this milestone, we should address the following tasks/features:

pallet-services

This milestone goals are:

1. Getting EVM fee resolved, from pallet-services (see #XYZ for more information)
2. Make Lookups faster, by introducing auxiliary storages and runtime APIs (with RPCs)

• [x] #634
• [x] #635
• [x] #636
• [x] #637
• [x] #638
• [x] #644
• [x] #648

Gadgets

This milestone goals are:

1. Convert dfns/cggmp21 gadget into blueprint (manual process)
2. Convert FROST gadget into a blueprint (manually)
3. Prepare Gadget shell to use on-chain data to pull blueprints and execute them (natively for now).

• [ ] [SPEC] Writing Native Tangle Service Blueprints (TSB)
• [ ] [SPEC] Testing Tangle Service Blueprints (TSB)
• [ ] [TASK] Publish dfns/cggmp21 as native Tangle Service Blueprint (TSB)
• [ ] [TASK] Publish FROST as native Tangle Service Blueprint (TSB)
• [ ] [TASK] Gadget Shell v2

Deliverables and timeline

TBD

[drewstone]

My goal for this milestone is to

1. Be able to write a blueprint and deploy it on chain (gadget blueprint create, gadget blueprint deploy)
2. Create a service request for that blueprint and select the configuration onchain. (Polkadot Apps, execute the extrinsic)
3. Have the participants involved execute that service. (run the service, submit results to the chain).

Gadget blueprint create (Finishing the protocol-template)

We have early beginnings of the protocol template, which compile the gadget into a binary and provide a hash in the CI. What we don't have is the full picture, but we can start building that out now. The full picture will require:

• (P0) Adding the smart contracts to this environment. This includes a boilerplate registration and request hook/contract. I believe this should be apart of the template.
• (P0 - P1) Test environment within the protocol-template structure. Can I test my blueprint w/ a mocked service instance?
• (P2) Integrating this into a CLI that we download with a single wget or curl cmd.

Gadget blueprint deploy

• (P0 - P1) Can I deploy a blueprint through Polkadot Apps UI? Does it need a CLI?
• (P2) Integrate deploy command to this CLI.
• (P2) It likely will need to read in a private key and submit the extrinsic that deploys a blueprint.

Gadget integration

• (P0) Shell manager should find all blueprints this shell should watch for, using an ongoing event listener, and download the binaries.
• (P0) Shell manager should listen for any new service instances/jobs from the watched blueprints, using an ongoing event listener, and execute the target binary.
  • How does gadget submit extrinsics? Does it have access to the keystore?
  • Possibly, the gadget binary sends the result to the shell manager who manages transaction submission.
• (P0) The gadget does still listens to its job dispatch system. This job dispatch system is a trait first and foremost, which we have a Substrate implementation for.
• (P0) The gadget has a trait for submitting the job result. This shouldn't apriori depend on any blockchain unless you want to submit to a chain. impl JobSubmitter for TangleJobSubmitter.
• Testing environment. Full test env includes EVM smart contracts, gadget, tx submission against Tangle.
