On Ep. 72 of Infinite Jungle, Christine speaks with Robert Miller, Product Lead at Flashbots, and Lily Johnson, Rust Engineer at Astria Labs, about the launch of BuilderNet. BuilderNet is Flashbot’s latest product designed to enable collaborative block building on Ethereum. It allows third-party builders to create blocks based off shared private order flow. It also incentivizes users, wallets, and apps to share their order flow with BuilderNet and earn kickbacks from the MEV created from their transactions. Christine and Lily grill Robert about the design of BuilderNet, its timeline, and motivation.
