Trying to regulate DeFi is a huge challenge because in a truly decentralized system, there should be no centralized actors to make and enforce rules for. This could make combating illicit finance challenging since traditionally, regulation has been targeted at centralized intermediaries. Yet Rebecca Rettig, Chief Legal and Policy Officer at Polygon Labs; Michael Mosier, the co-founder of boutique law firm Arktouros; and Katja Gilman, senior lead for public policy at Polygon Labs, published a paper last week that proposes to do just that.
Rettig and Mosier join Unchained to discuss what prompted them to write the paper, what the difference is between "onchain CeFi" and "genuine DeFi," how targeting high-risk wallets can be one part of the solution, how critical communications transmitters (CCTs) are another piece of the puzzle,and what next steps they are pursuing.
