Over the course of the day on 09/27 the BloXroute ethical relay was receiving and returning bad blocks to validators from one of our block builders running an experimental build strategy that resulted in missed slots.
This builder was improperly committing transactions and caused improperly formatted blocks. Because the relay was not simulating blocks from known builders these blocks were getting sent to validators causing them to miss slots due to proposing blocks with improper receipts or log blooms. A total of 15 slots were missed due to this issue.
BloXroute’s relay was not simulating blocks from internal builders and was instead relying on these builders to submit valid blocks.
This was resolved:
Proposal This proposal is to return back 11 ETH that were sent to the Lido Execution Layer Rewards Vault.
If the proposal is supported, then an on-chain vote will be launched to send 11 ETH from the Lido DAO Treasury to the address 0xea48ba2edefae9e4ddd43ea565aa8b9aa22baf08.
