Mempool Censorship

Action

Mempool censorship represents a deliberate exclusion of transactions from block inclusion, despite meeting fee requirements, based on their content. This interference, typically enacted by miners or validators, disrupts the neutrality of the blockchain and introduces a form of control over transaction propagation. Consequently, it impacts the fundamental premise of permissionless systems, potentially affecting decentralized finance (DeFi) applications and derivative settlement. The ability to selectively censor transactions introduces systemic risk, particularly within markets reliant on timely and predictable execution, such as options and perpetual futures.
