.According to a recent blog post, Ethereum co-founder Vitalik Buterin on October 1 as suggested “partial block auctions” as a way to reduce the censorship issues. The co-founder of Ethereum suggested in a recent blog post that in order to prevent ETH censorship after The Merge, developers should have tighter rules on their ability. If developers win an auction, their authority would be slightly restricted rather than giving them free rein to create the entire block.
Right approach to restrict block production power
Buterin contends that builders will maintain sufficient power to profit from the proposer/builder separation while also being capable of extracting almost all of the maximal extractable value (MEV) (PBS).
The three potential approaches of restricting block production power are inclusion lists, proposer suffixes, and pre-commit proposer suffixes.
In the inclusion list paradigm, the proposer provides an inclusion list, which is basically a list of operations that should be in the block unless the builder fills a block with other transactions. Despite the design’s simplicity, there are still certain misuse potentials for the builder. In addition to additional responsibilities for proposers and problems with incentive compatibility.
An alternate form that enables the proposer to add a suffix to the block is called a proposer suffix. When a builder creates a block, the proposer’s intentions are hidden from view, and the proposer is free to append any transactions the builder overlooked to the end of the block. The shortcomings of this system are comparable.
The proposer pre-commits to a Merkle tree or KZG on the set of transactions. It intend to add to the block when using Pre-commit proposer suffixes. While the proposer adds the suffix, the builder creates the block, removing the latter’s MEV possibilities while also addressing other issues.
Buterin believes that the role of the proposer and builder should be as little as possible. This, however, leaves a large number of crucial duties unfilled, making the addition of a “third actor” to the block production process unavoidable.
Ethereum developer’s know how to handle centralization
Ethereum’s core developers appear unfazed with centralization, despite the controversy around it in the larger community. The topic was examined during a pre-Merge stage in stage. As a result majority of developer agreed to upgrade the present MEV designs in order to improve PBS.
As per the mining stats, Ethereum’s heavy reliance on Flashbots, which also seems to be a single server for building blocks. This was sufficient to cause centralised worries about the ecosystem’s one point of failure. According to data, Flashbots are believed to have created 83.5% of all relay blocks.
