MEVpool, The Best Bandaid We Have For MEV

A worker extraction worker. This phrase is basically one of the largest basic risk spaces for Blockchain systems. Blockchain's original concept guarantees incentives for mining workers' work (or other participants in consensus who define transactions) to earn revenues based on any initial support that is in addition to each block in addition to the fees that users pay to confirm their transactions.

These two things are no longer the only sources of revenue that stimulates the actions of miners. There are now more complex contracts and protocols to facilitate the creation of different assets and exchange between them. These contracts, according to the design, allow any person to access any person. If you have a required origin, and you can fulfill the specified exchange conditions, any user of one side can interact with nodes or protocol to exchange assets.

Given that miners ultimately decide what transactions are accepted in the blocks, this gives miners the preferential access to “jumping on the line” in interacting with these contracts and protocols. This is a serious problem, depending on the degree of complexity participating in the successful extraction of value from different contracts or protocols.

This creates a huge central pressure to extract these contracts and protocols more complicated. They have mines capacity To collect all this value, but in order to do this, they actually need to analyze the current situation of these contracts. The more complicated the contract, the more sophisticated and expensive the analysis, and the more centralized it creates for miners.

This is terrible to resist control.

Suggestion of the classroom

ETHEREUM is the MEV child's poster. Due to the high complexity of the contracts published on Ethereum, the quantity of the MEV created in that series was very large. Of course, they reached an attempt to respond to this issue.

The proposal establishment is sought to alleviate the central risk of mev by creating the separation between the two roles involved in moving Blockchain forward. Builders (prohibiting templates) deals with the role of transactions actually in blocks, and the proposals (mines/export workers) chooses between the available block molds to determine the most profitable lists. The idea behind the suggestion is that we can let the central affect the producers of the template, but protecting miners/exporting it. As long as there is a competitive market for the production of the template, things should be safe.

In practice, this is not what happened. The truth is that there are only a few competitive builders, and when the most profitable producers decide to control something, it is actually subject to every mine/maker who chooses to use these profitable block molds. Given that it is not logical economically not to choose the most profitable template, this does not already solve the risk of censorship.

mevpool

the MEVPOOL suggestion By Matt Corallo and 7D5X9 it is an attempt to amend the PBS suggestion for Bitcoin in a way that already provides the risk of censorship.

The main difference between PBS and MEVPOOL is the use of external sources to build the template is not total, in mevpool miners eventually build the end block template themselves. They simply suffer from the use of external sources for the selection of the sub -group of transactions that improve the MEV extraction, including those in the blocks they build. This aims to allow the mines to increase their cut from MEV while maintaining freedom to include any transactions they want, instead of choosing the binary to accept control to make the maximum profit or constant profit to prevent control under a TV program.

The proposal requires creating a market for the market for host applications where MEV extracts can publish their proposed transactions and fees that they will pay to miners to include them in a block. They will allow the extractor to determine the conditions under which they will pay in exchange for the conclusion of transactions, that is, only if the first treatment of interaction with a specific contract in the mass. Markets will also support sealed or unproked requests, meaning that sealed requests are orders in which the actual proposed treatment of mines is not detected until they reach the mass.

How does this work? All mines need to be fragmented by the treatment that must be included in the Merkel tree to start mining, do not need full treatment in order to find a valid mass and go to broadcast. But they need to know that the treatment is valid. This is the role that the market's positions should fill.

There are two ways they can do. First, the simplest way is to be a third trusted party. Mev's extracts will provide their transactions for deportation operators, and miners will contact these lenses. After that, they will request a list of sealed and unbearable bids from the Marketplay operator, including the retail needed to include sealed bids, and get a custom piece of the program. Once Blockhaader is successfully found, they will send the block from the lost data to the deportation.

The deportation will then include full sealed transactions, broadcast the mass itself, then send the full sealed transactions worker so that they can broadcast the mass as well. During this entire process, MEV Extracting will be kept with Marketplace Relay, and it was released to the mining factor after finding a valid block.

This requires putting a lot of confidence in the relay, both by miners as well as the MEV extracts who pay them.

The second option is to use the reliable implementation environment (TEE) to deal with the construction of mass molds by miners, as well as dealing with the coded bids. Mines will run the designated template program and the Bitcoin knot inside the starting point. After mining workers received the sealed and unbearable bids and building their bloc, the starting point on the testimony will be expected to the mass and provide the market deportation with a session key.

The market will encrypt the sealed transactions and the treatment that pays the mines to the key to the session. After a mine worker finds a set of difficulty that meets the goal of difficulty, the starting point would decode the sealed transactions and allow them to broadcast the full mass and collect its fees from MEV extracts. In this scenario, everyone concerned must trust the starting point for staying safe.

The end result

It is very likely that the final result of this will be similar to PBS on Ethereum. There are only a few adult builders who build an improved MEV molds for workers, and they all have transactions that were submitted directly to them outside the range of MEMPOOL. MEVPOL Marketplace, both differences, are documented from public broadcasting fees on requests submitted to them to allow ordinary users to estimate appropriate fees. If the large markets can attract transactions that have not been sent to another place and withholding fees, this may affect users in general.

Also, although it allows the miners the freedom to choose their own transactions outside the improved sub -group MEV, it still leaves room for large markets that receive special transactions to benefit from this situation. These markets can compel miners to control other transactions by blocking the request book data from them if there is no competitor with access to the same information.

In the end, I do not see this a solution to the MEV case, or more than Bandaid or alleviate the worst possible effects of it. It does not completely remove central risks and pressure, but it reduces it in certain areas.
