Credible Commitments

In this episode of Credible Commitments I chat with Kubi Mensah CEO/Co-founder at Gattaca, the company behind Titan Builder. We discuss block building from first principles, Ethereum's evolving market microstructure featuring a dense discussion on Prop AMMs, and what takes to build a world class product-centric organization.

In this episode of Credible Commitments I chat with Michael from Quasar Builder (#2 block builder on Ethereum). Michael started out mining Bitcoin before turning to block building, launching Quasar in 2025 with no privileged orderflow and climbing the leaderboard from the public mempool. The episodes progresses as we discuss PropAMMs and the market structure behind orderflow dynamics. Orderflow is downstream of trust. In particular we break down different types of orderflow and discuss what sharing orderflow between competing parties actually looks like and where multi-party block construction is heading. We close by discussing: ACE, faster blocks, and coordination as the next frontier including where ePBS fits into the auction's future, and a final question worth sitting with: is the public mempool beyond saving?

In this episode of Deeply Intents I chat with Markus Schmitt, Founder of Propeller Heads. We dive into PropAMMs: what they are and how they are changing the market microstructure on Ethereum. In addition we unpack the Propeller stack of Tycho, Fynd, and Turbine which will enable a trustless trading experience on Ethereum main-net.

In this episode of Deeply Intents I chat with Quintus from Flashbots. We discuss the current transaction supply chain and how PropAMMs fit in. Quintus provides fresh insights and a wealth of technical understanding around this new market micro structure. In particular, the ways in which the working processes of PropAMMs affect determinants of transaction costs, prices, quotes, volume, and trading behavior.
