## Description

Clip The video features a researcher from Primav discussing the concept of pre-confirmation in blockchain transactions, specifically within the context of Ethereum. Pre-confirmation is a mechanism that provides users with a fast guarantee that their transaction will be included in the next block, improving user experience and potentially increasing profit for activities like arbitrage.

The researcher explains the roles of two main actors in this system: bidders, who are willing to pay for pre-confirmations, and pre-confirmation providers, who can credibly promise transaction inclusion. Primav has developed MavCommit as an open network where anyone can participate as either role.

The talk delves into why block builders might provide pre-confirmations, emphasizing their specialized knowledge and capability to do so quickly and economically. However, since multiple builders compete to build blocks, a pre-confirmation from one does not guarantee inclusion if another builder is selected. The speaker suggests that even probabilistic pre-confirmations can be valuable for certain strategies like cross-chain arbitrage.

Primav's solution includes a side chain with fast block times for settlement and a decay mechanism incentivizing timely pre-confirmations. The protocol also emphasizes privacy for bids and commitments through encryption and special cryptographic commitments.

In conclusion, MavCommit aims to offer an open network with strong cryptographic guarantees for timely
