While Flashbots Alpha has been and continues to be successful it offers incomplete trust guarantees. It is not permissionless because miners who adopt it have to be whitelisted by MEV-Relay in order to be forwarded bundles. It is not completely private because bundles can be seen by miners prior to inclusion on-chain. Lastly, Flashbots Alpha offers no finality protection against chain reorgs. While finality is important, we are focusing first on permissionless and complete privacy as the next design goals to achieve.
