Adds a new `/lighthouse` API call to the VC which allows the list of beacon nodes to be updated dynamically at runtime.
An entirely new beacon node list is provided to the VC so it effectively adds, removes or reorders nodes to match the new list.
This can then be used in Siren, which will enable a "drag to reorder" system along with adding and removing beacon nodes while the VC is on. This will make it unnecessary to reboot the VC when users want to simply add or remove a BN from the list.
N/A
After the electra fork which includes EIP 6110, the beacon node no longer needs the eth1 bridging mechanism to include new deposits as they are provided by the EL as a `deposit_request`. So after electra + a transition period where the finalized bridge deposits pre-fork are included through the old mechanism, we no longer need the elaborate machinery we had to get deposit contract data from the execution layer.
Since holesky has already forked to electra and completed the transition period, this PR basically checks to see if removing all the eth1 related logic leads to any surprises.
#6970
This allows for us to receive `SingleAttestation` over gossip and process it without converting. There is still a conversion to `Attestation` as a final step in the attestation verification process, but by then the `SingleAttestation` is fully verified.
I've also fully removed the `submitPoolAttestationsV1` endpoint as its been deprecated
I've also pre-emptively deprecated supporting `Attestation` in `submitPoolAttestationsV2` endpoint. See here for more info: https://github.com/ethereum/beacon-APIs/pull/531
I tried to the minimize the diff here by only making the "required" changes. There are some unnecessary complexities with the way we manage the different attestation verification wrapper types. We could probably consolidate this to one wrapper type and refactor this even further. We could leave that to a separate PR if we feel like cleaning things up in the future.
Note that I've also updated the test harness to always submit `SingleAttestation` regardless of fork variant. I don't see a problem in that approach and it allows us to delete more code :)
We would like to reuse the `notifier` and `latency_service` in Anchor. To make this possible, this PR moves these from `validator_client` to `validator_services` and makes them use the new `ValidatorStore` trait is used so that the code can be reused in Anchor.
While the Lighthouse implementation of the `ValidatorStore` does not really care about blobs, Anchor needs to be able to return different blobs from `sign_blocks` than what was passed into it, in case it decides to sign another Anchor node's block. Only passing the unsigned block into `sign_block` and only returning a signed block from it (without any blobs and proofs) was an oversight in #6705.
- Replace `validator_store::{Uns,S}ignedBlock` with `validator_store::block_service::{Uns,S}ignedBlock`, as we need all data in there.
- In `lighthouse_validator_store`, just add the received blobs back to the signed block after signing it.
Prevent running `lighthouse vc --http-port <PORT>` without `--http`.
Issue: https://github.com/sigp/lighthouse/issues/7402
Added requires `--http` when using `lighthouse vc --http-port <PORT>`.
Implemented a test code for this issue.
- Create trait `ValidatorStore` with all functions used by the `validator_services`
- Make `validator_services` generic on `S: ValidatorStore`
- Introduce `LighthouseValidatorStore`, which has identical functionality to the old `ValidatorStore`
- Remove dependencies (especially `environment`) from `validator_services` and `beacon_node_fallback` in order to be able to cleanly use them in Anchor
Changes the endpoint to get fallback health information from `/lighthouse/ui/fallback_health` to `/lighthouse/beacon/health`. This more accurately describes that the endpoint is related to the connected beacon nodes and also matched the `/lighthouse/beacon/update` endpoint being added in #6551.
Adds documentation for both fallback health and the endpoint to the Lighthouse book.
