Proposer Builder Separation introduces a governance and operational control split where the entity responsible for proposing a block cannot unilaterally determine its internal transaction composition. This separation is a deliberate design choice to decentralize the power over transaction ordering and block finalization. Such a control mechanism is intended to prevent collusion and censorship at the consensus layer.
Security
The architectural separation enhances protocol security by making it economically infeasible for a single proposer to capture all MEV without external coordination with a builder. This design reduces the attack surface for centralized manipulation of the transaction sequence. Maintaining this separation is crucial for the long-term resilience of the network’s integrity.
Mechanism
This structural change mandates a specific interaction mechanism where builders submit fully formed, encrypted blocks to proposers, who then select the highest-bidding block. The separation fundamentally restructures the MEV extraction pipeline, moving the optimization function away from the consensus validator. Understanding this new mechanism is key to modeling post-merge execution flow.
