Flashbots Architecture

Flashbots is a research and development organization focused on mitigating the negative externalities of MEV by creating a transparent and democratic ecosystem for transaction ordering. Their primary contribution is the development of a relay infrastructure that allows searchers to submit transactions privately to validators, bypassing the public mempool.

This architecture aims to reduce the prevalence of sandwich attacks and other predatory behaviors that harm end-users. By creating a marketplace for transaction ordering, Flashbots attempts to align the incentives of validators with those of the broader network.

This represents a significant evolution in protocol physics, shifting the burden of transaction management away from the base layer. It is a crucial study in how systems risk can be managed through architectural design rather than just regulatory intervention.

The system relies on a complex game-theoretic model to ensure that validators are compensated fairly for their role in the network.
