In parallel with developing the finality provider SDK, we need to develop the BSN finality providers, including the rollup BSN finality provider and Cosmos BSN finality provider. We will start with rollup BSN finality provider as first step, then tap into the Cosmos finality provider.

Implementing rollup BSN finality provider includes the following tasks

• Signing context support
• Remove the dependency to finality gadget (WIP opstackl2: temporarily disable Finality Gadget dependency #504)
• Create rollup-bsn-fp folder
  • Refactor Config i.e., define BabylonConfig, RollupConfig and CosmosConfig that serve their respective FPs
  • Constructor for FinalityProviderApp for rollup BSN FPs
  • Migrate rollup BSN FP e2e tests to the folder
• Finish rollup fpd
  • CLIs for rollup fpd
• Replace consumer with BSN in rollup finality provider (rename all chain/consumer to BSN #339 )
• Implement missing methods in ConsumerController (rollup: implement missing functions for rollup BSN controller #506 )
• Improve e2e test framework (e2e: refactor e2e test framework #527 )
• More unit/e2e tests (e2e: more e2e tests for rollup BSN FPs #528 )
  • make sure FP works with latest contract
  • make sure CLIs work properly
