proposer-builder separation

Proposer-builder separation was designed to reduce validator centralisation caused by MEV extraction.提议者-构建者分离旨在减少由 MEV 提取引起的验证者中心化。

Under PBS, validators propose blocks from bids submitted by specialised builders, separating the two roles entirely.在 PBS 下，验证者从专业构建者提交的出价中提议区块，彻底将这两个角色分离。
