Trustless Sequencing

Definition ∞ Trustless sequencing is a method of ordering transactions on a blockchain network that does not rely on a single, centralized entity or a small group of trusted intermediaries. This approach aims to prevent manipulation or censorship of transactions by ensuring that the sequence of operations is determined by decentralized and verifiable means. It enhances the security and fairness of transaction inclusion. This system is vital for true decentralization.
Context ∞ Trustless sequencing is a crucial area of research and development in blockchain technology, particularly concerning Maximal Extractable Value (MEV) and fair transaction ordering. Discussions often center on protocols designed to achieve this goal, such as decentralized sequencers for rollups. A critical future development involves widespread implementation of these mechanisms to bolster network integrity.
