## Description

Clip The video discusses the current and idealized futures of blockchain technology, focusing on the challenges of proposer delegation, pre-confirmations, and universal synchronous composability. It highlights that there is no current solution allowing proposers to self-preconfirm while participating in the public PBS pipeline without changes to the pipeline itself. The discussion also explores how non-delegating proposers can exist but face difficulties participating in the current PBS system. The speaker suggests that high proposer participation is crucial for the vision of universal synchronous composability to be realized with high utility. Opinions on whether it's acceptable for all participants to delegate in the short term are shared, acknowledging that this is a contentious issue.

The conversation shifts to issues of roll-up fragmentation, user experience challenges due to liquidity fragmentation across different roll-ups, and potential solutions like shared sequencing protocols. However, concerns about censorship resistance and sovereignty loss for roll-ups are raised. There's also a debate on whether L1 proposers will sequence for L2s and how pre-confirmation gateways might be allocated via a registration smart contract on L1. The video concludes with technical discussions about possible implementations, including using SGX for trust issues and how MEV could flow back to L2s through auction mechanisms.

Overall, the video presents a deep
