# Proposer-builder separation {#proposer-builder-separation}

Present-day [Ethereum](/) validators create _and_ broadcast blocks. They bundle together transactions that they have heard about through the gossip network and package them into a block that is sent out to peers on the Ethereum network. **Proposer-builder separation (PBS)** splits these tasks across multiple validators. Block builders become responsible for creating blocks and offering them to the block proposer in each slot. The block proposer cannot see the contents of the block, they simply choose the most profitable one, paying a fee to the block builder before sending the block to its peers.

Block builders become responsible for creating blocks and offering them to the block proposer in each slot. The block proposer cannot see the contents of the block, they simply choose the most profitable one, receiving a fee from the block builder (or the builder pays a bid to the proposer) before sending the block to its peers.

This is an important upgrade for several reasons. First, it creates opportunities to prevent transaction censorship at the protocol level. Second, it prevents hobbyist validators from being out-competed by institutional players that can better optimize the profitability of their block building. Third, it helps with scaling Ethereum by enabling the Danksharding upgrades.
