What is the Control of Proposer Builder Separation?

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.

What is the Security of Proposer Builder Separation?

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.

What is the Mechanism of Proposer Builder Separation?

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.
