mev [re]search-athon ([sign up](https://lu.ma/bs3kx2pr))

Date: Saturday, March 4, 2023 Venue: pirateship hackerhouse at ethdenver Livestream: https://meet.google.com/fot-iiof-jkm Food: Breakfast + light lunch will be provided Brought to you by Flashbots. Special thanks to Rook, Blocknative, Gauntlet, DBA, Fenbushi. wtf is a [re]search-athon Every now and then, when I look around, I find myself, along with many of you lingering on this page, trapped in the parable of the blind men and an elephant. While MEV is a critical metric for network security in any distributed system secured by economic incentives, it is also a multidiciplinary design space that lies in the intersection of economics, security and cryptography. While anyone may bring something to the table regardless of domain of expertise, cross-domain collaboration often incurs higher communications overhead due to vastly different frames of references. Moreover, boundaries of organizations add friction to open collaboration in exploratory research or emergent design problems. We often see withholding of information due to differences in strategic interests, unnecessary redundancies or gaps across organizations, or failure to align on a common understanding due to a lack of shared context. We end up circling around local optima, involuntarily fall into turf wars from unnecessary collisions.
