+Lending protocols like Maker and Aave require users to deposit some collateral (e.g. ETH). This deposited collateral is then used to lend out to other users.
 
 Users can then borrow assets and tokens from others depending on what they need (e.g. you might borrow MKR if you want to vote in a MakerDAO governance proposal) up to a certain percentage of their deposited collateral. For example, if the borrowing amount is a maximum of 30%, a user who deposits 100 DAI into the protocol can borrow up to 30 DAI worth of another asset. The protocol determines the exact borrowing power percentage.

 In post-Merge Ethereum, validators (having made security deposits of 32 ETH) come to consensus on the validity of blocks added to the Beacon Chain. Since 32 ETH may be out of the reach of many, [joining a staking pool](/staking/pools/) may be a more feasible option. Nevertheless, a healthy distribution of [solo stakers](/staking/solo/) is ideal, as it mitigates the centralization of validators and improves Ethereum’s security.
 
-However, MEV extraction is believed to be capable of accelerating validator centralization. This is partly because, as validators [earn less for proposing blocks](/roadmap/merge/issuance/#how-the-merge-impacts-ETH-supply) than miners previous did, MEV extraction has greatly [influence validator earnings](https://github.com/flashbots/eth2-research/blob/main/notebooks/mev-in-eth2/eth2-mev-calc.ipynb) since The Merge.

 Larger staking pools will likely have more resources to invest in necessary optimizations to capture MEV opportunities. The more MEV these pools extract, the more resources they have to improve their MEV-extraction capabilities (and increase overall revenue), essentially creating [economies of scale](https://www.investopedia.com/terms/e/economiesofscale.asp#).

 Permissioned mempools would also accelerate the centralization risks described in the previous section. Large pools running multiple validators will likely benefit from offering transaction privacy to traders and users, increasing their MEV revenues.

 ### Proposer-Builder Separation {#proposer-builder-separation}
 
 In both proof-of-work and proof-of-stake, a node that builds a block proposes it for addition to the chain to other nodes participating in consensus. A new block becomes part of the canonical chain after another miner builds on top of it (in PoW) or it receives attestations from the majority of validators (in PoS).
 
-The combination of block producer and block proposer roles is what introduces most of the MEV-related problems described previously. For example, consensus nodes are incentivized to trigger chain reorganizations in time-bandit attacks to maximize MEV earnings.

 [Proposer-builder separation](https://ethresear.ch/t/proposer-block-builder-separation-friendly-fee-market-designs/9725) (PBS) is designed to mitigate the impact of MEV, especially at the consensus layer. PBS’ major feature is the separation of block producer and block proposer rules. Validators are still responsible for proposing and voting on blocks, but a new class of specialized entities, called **block builders**, are tasked with ordering transactions and building blocks.
