Feature request
Summary
Currently, our light client only supports
LightClientUpdate
. This type of update can currently only be used to update the next sync committee when moving in-between sync committee periods. We should also add support forLightClientFinalityUpdate
for finality updates within the same sync committee period.Problem Definition
Although
LightClientUpdate
could also be used update the finalized header within the same sync committee period, the ethereum full node's beacon api only returns the earliest such update. This essentially makes these updates unusable when updating the finalized header within the same sync committee period. For this, we can useLightClientFinalityUpdate
, since there is an api's to receive the latest such update.Use cases
We need this to have the light client be usable in testnet and mainnet.
