Enable multi node attestation consensus for the VC
Allow for the VC to query all BN's at the beginning of each epoch and only enable attestation for that epoch if source and target checkpoint matches for a threshold of BN's
TODO
- [x] make sure we are only comparing relevant fields in attestation data
- [x] As an optimization only check attestation data for the first slot in an epoch
- [ ] Ensure we only fetch attestation data for the BN whose attestation data matches consensus
- [ ] Allow for consensus threshold to be set via CLI flag
- [ ] Write tests
- [ ] Test w/ single and multi bn setups w/ multiple consensus thresholds
@yorickdowne based on our convo in Buenos Aires, I thought you might find this draft PR interesting
Yes, I find it very interesting! Thank you! (This is the corpo account. I'm forwarding this to the Galaxy team as a potential option)
Just curious are you gonna just pick one BN to get the ghost head (beacon_block_root)?
@0xmrree im actually doing most of my development on this branch at the moment https://github.com/eserilev/lighthouse/pull/26
i've isolated the changes there to make things a bit easier to review
I'm not using the beacon block root at all. I'm just comparing the source and target checkpoints across all connected BN's and if a threshold agrees, I attest with one of the nodes that are in agreement. If a consensus threshold isnt reach, attestation is disabled for that epoch.
