Several tweets from different users have raised concerns about the presence of invalid blocks being broadcasted and finalized on the Mainnet, potentially leading to missed or invalid block proposals. The issue is attributed to the relay forwarding invalid blocks to validators without proper verification. The lack of in-protocol consequences for this behavior has prompted discussions about implementing ePBS in Electra to address the problem. Additionally, the potential for MEV blocks to dominate the chain and censor Ethereum users has been highlighted, with a call for the use of Besu and its layered transaction pool to mitigate the issue. The need for competitive relays to report not only the header and payment but also the size of compressed blocks has also been suggested to incentivize validators to minimize bytes per fee paid.
larger blocks are more likely to get reorged so greedy validators have some incentive to minimize bytes per fee paid should a competitive relay report not just (header, payment) but also size of compressed block? cc @drakefjustin @uriklarman @beaverbuild https://t.co/FVCpeGyxm5
Today, a MEV relay posted 9 invalid blocks that were finalized on Mainnet. All execution clients invalidated the blocks, saving us from disaster. But MEV blocks still make up the vast majority of blocks on chain & can censor Ethereum users๐ซ Enter Besu & its layered tx pool ๐งต https://t.co/oRTWmlDzjc
Relays will literally forward invalid blocks to validators but check for ofac txs instead of going thru enshrinement https://t.co/p7QhRYmAVM
mev-boost is fundamentally flawed. Some builder(s) are producing invalid blocks and relayers are recklessly providing them to validators, leading to a missed/invalid block proposal. There are no in-protocol consequences for this behavior, so let's talk about ePBS in electra. https://t.co/PFPz79D1lJ
mainnet is having lots of invalid blocks coming from the same builder. The relay should never broadcast blocks without verification. We should consider including ePBS in Electra. Please raise support for this to be discussed in ACD https://t.co/51DOZ6cEVw
