validator registrations with lighthouse

[xenowits]

🎯 Problem to be solved

We want to support validator registrations with lighthouse Validator Client.

Ciaran already worked on such a PR 7 months back. But since then, we have formalized the solution with this design doc. We have also added an internal proposal for a new endpoint /eth/v1/validator/proposer_config to standardize how different VCs fetch override values for pubkey & timestamp.

So, in a nutshell, we want lighthouse VC to be capable of fetching override values from charon DVT and use those values to perform validator registrations in a DV setting.

🛠️ Proposed solution

• Fix the outdated PR with a new PR branching off latest unstable branch of sigp:lighthouse. Use the original PR as a reference.
• Add support for the new endpoint /eth/v1/validator/proposer_config to lighthouse VC

🧪 Tests

• [ ] Tested by new automated unit/integration/smoke tests
• [ ] Manually tested on core team/canary/test clusters
• [ ] Manually tested on local compose simnet
