Mempool Neutrality

Mempool neutrality describes a state where a blockchain network allows all valid transactions to enter the block building process without discrimination or preferential treatment. It is a critical aspect of market microstructure in decentralized finance.

If the mempool is not neutral, certain actors can exploit their position to front-run or sandwich other users' trades. This undermines the fairness of price discovery and discourages honest participation.

Achieving neutrality requires robust consensus mechanisms that prevent block producers from censoring or delaying transactions for personal gain. It is a primary goal for developers building next-generation scaling solutions.

When neutrality is compromised, the network becomes susceptible to rent-seeking behaviors that extract value from end-users. Monitoring the mempool for signs of bias is essential for maintaining trust in the system.

It is the bedrock of a truly decentralized order book.
