In Ethereum, every time a block is created, a parallel economy exists that is invisible to the average user. The next network update, postponed to late 2026, will make this process even more transparent.
The parallel economy of networks is based on the maximum extractable value, known by the acronym MEV in English.Maximum value that can be extracted). This is the value that the block builder can capture and manipulate to grant permission to a particular actor. Sort, include or exclude transactions. All of this happens before the block is published on the chain.
Hence the Gramsterdam update There is a structural purpose to visualize and regulate That FSM processtoday operates in a state of opacity.
The reason why FSM occurs is Transactions are not processed in the order they arrivebut in the one that decides who builds the blocks. This fact allows for special actors such as: bot or an opportunity seeker – can detect profitable operations in the menpool (the space where transactions wait), predict them, and reorder them or intervene midway for profit.
This mechanism also facilitates third parties Capturing value through practices such as arbitragehe front line or attack sandwichjust like Vitalik Buterin suffered recently. Ethereum’s co-founders are among those in an advantageous position due to their technical capabilities and privileged access to the block construction process.
Changes to MEV are applied according to specifications in EIP-7732. EIP-7732 is an improvement proposal proposed by the majority of block supporters. Outsource the construction of running content From the block to a third party called a constructor.
To do that, you need to trust the intermediary —Relay Server—provides no cryptographic guarantees about its operation. This trust model without technical support is at the heart of the problem Gramsterdam is trying to solve and is among the most important improvements.
It is worth remembering that Ethereum Improvement Proposals (EIPs) formalize changes to the protocol and define how they are implemented. In this case, separation of proposer and builder is proposed (ePBS, EIP-7732). This is done by specifying whose role in the protocol. Choose who will assemble the consensus block and its content of execution. This eliminates dependence on intermediaries and opaque third parties.
Simply put, what is at stake today depends on trust agreements between private entities. Provides visible technical guarantees for the protocol itself.
From opaque markets to verifiable exchanges
suggestion We guarantee that honest bidders will receive payment from the builder. Regardless of the latter’s actions. Find the content of an honest constructor that is the canonical head of the chain.
To achieve this, a new category of participants with a minimum stake of 1 ETH will be introduced to the consensus chain. these are, Signed offer with block identifier and the amount payable to the proposer.
To verify that constructors meet their commitments, EIP-7732 assigns a subset of validators to a committee (Payload Timeliness CommitteePTC). take care of Prove whether the constructor revealed committed execution Check the availability of relevant data in a timely manner. This bulk validation mechanism eliminates the need to trust relay servers individually.
On the other hand, the technical discussion regarding the actual scope of the proposal as a solution for MEV remain active within the research community. EIP-7732 provides proposers with the option, but is not required, to use third-party trustless mechanisms.
For very large MEV payments or more complex contracts such as turn-of-validation auctions, second-layer network pre-validation, and zero-knowledge proof auctions, actors can May be able to continue operations through external intermediaries.
According to the designers, this mechanism is believed to be competitive enough for a significant portion of the network to adopt it as a standard, while leaving an incentive for alternatives outside the protocol to continue to exist.
