hello Flashbots community!

on March 17, 2023 at 12pm UTC, the ultra sound relay launched optimistic relaying. after monitoring the launch and collecting data this weekend, we are happy to share [“An optimistic weekend”](https://github.com/ultrasoundmoney/mev-boost-relay/blob/prod-optimistic-relaying/docs/optimistic/an-optimistic-weekend.md) – a writeup of our initial results.

we look forward to continuing the discussion in [Community Call #2](https://collective.flashbots.net/t/mev-boost-community-call-2-30-mar-2023/1465). please reach out to us if there are any questions or concerns!
