The FastLane protocol (AKA ‘Polygon FastLane’ or ‘PFL’) is designed to enhance the Polygon blockchain by reducing transaction spam.

Nodes based on GETH, such as those run on Polygon PoS and BNB chain, create an inherent correlation between transaction quantity and trading success that incentivizes searchers to spam the network. The FastLane protocol works by overriding this mechanism with a highly efficient and transparent auction system.

Reducing spam can only be accomplished with the help of Polygon’s validators. Onboarding for validators is as simple as and then . Participating validators are rewarded for safeguarding the network by receiving the proceeds of any auctions occurring during their blocks.
