Builder Centralization Risks

Builder centralization risks occur when a small number of entities have the capability to assemble blocks in a way that maximizes MEV, effectively controlling the content of the blockchain. Because building a block requires specialized knowledge and high-performance infrastructure, the barrier to entry is very high.

This leads to a concentration of power, where these builders can choose to censor certain transactions or prioritize others for their own benefit. In the context of financial derivatives, this could allow builders to manipulate the settlement of trades or front-run large orders.

This centralization is a major threat to the censorship resistance of the entire network. If only a few builders exist, the network becomes fragile and subject to the whims of those builders.

Mitigating this risk is a top priority for researchers working on PBS ⎊ Proposer-Builder Separation ⎊ architectures. It is a critical challenge in ensuring that blockchain remains a neutral, fair, and decentralized platform for global finance.
