According to founder of Unstoppable Domains, they will be Registry Service Provider of .gram domain(if application is successful).

I assume this means that .gram domains won't be technically handled on TON blockchain or if it does, they would need a new smart contract that allows blocking and trademark and intellectual property rights(For example Instagram should be able to block insta.gram domain if they want to)

PS: Unstoppable Domains is a U.S. company and they have to obey the US copy right and criminal laws 😄
