Block Proposer Separation
Block Proposer Separation is a structural design choice in blockchain architecture that decouples the role of proposing a block from the role of constructing its contents. By splitting these duties, the network prevents validators from having direct control over transaction ordering, which mitigates censorship and centralizing tendencies.
In this model, builders specialize in optimizing the contents of the block, while proposers focus on the consensus-driven task of adding that block to the chain. This separation enhances the resilience of the network against malicious behavior and promotes a more competitive ecosystem.
It allows for the integration of specialized builder markets that operate independently of the consensus layer. This architectural shift is fundamental to the scalability and neutrality of modern blockchain protocols.
It creates a clearer distinction between the economic and security layers of the system.
