A Shared Mempool is a collective repository where unconfirmed transactions from multiple blockchain networks or layer-2 solutions are temporarily stored before being processed. Instead of each chain or rollup having its isolated mempool, a shared version allows for greater transparency and coordination across different parts of the ecosystem. This can enable more efficient transaction ordering, reduce front-running opportunities, and facilitate atomic swaps between disparate systems. It promotes a more interconnected transaction environment.
Context
News regarding Shared Mempools often pertains to advancements in cross-chain interoperability and the optimization of transaction processing across various blockchain networks. Their development is critical for building a more cohesive and efficient digital asset ecosystem. Discussions frequently address the technical challenges and security implications of such shared infrastructure.
This new layer decouples rollup execution from transaction ordering, using a BFT consensus to ensure fair, decentralized sequencing and atomic cross-chain state transitions.
