"In the landmark case of Hoop v. Doe,  the Chief Judge of the US District Court for the Southern District of Iowa approved alternate service of process on the defendants' wallet address using an NFT. The Court found that service provided in this manner was "reasonably calculated to reach" the defendants since all other methods of providing service were inadequate. This resulted in the Court entering a permanent injunction against disposition of the assets at issue, freezing them at the exchange level and preventing them from being disposed of on any exchange that performs KYC on its customers. It is my hope that many more such cases will be brought, and justice will become more prevalent on the blockchain." - J. Mason Bump
