In this system the ENS name is split up into two separate ERC721 tokens. One embodies the control of the domain (called the leasehold), while the other receives any tax proceeds of the domain (called the freehold). The leasehold token is always for sale at a self-assessed price, but its owner has to pay a set percentage of this value in tax (or rent) to the freehold owner. This incentivises an honest value assessment of the domain and disincentivises domain hoarding.\n\n"},{"attributes":{"bold":true,"link":"https://revoke.cash/"},"insert":"revoke.cash"},{"insert":"\nrevoke.cash is a very simple web interface that allows you to inspect all outstanding ERC20 allowances, so that they can be revoked or changed.

If the casino makes money, the value of Roscoin rises, if the casino loses money, its value falls proportionally. But remember, in the long run the house always wins. The Proof of concept can be expanded to allow for more DAO-like functionality by giving Roscoin-holders a vote about parameters of the contract, such as house edge or maximum bet size.\n\n"},{"attributes":{"bold":true,"link":"https://github.com/Bitcoin-com/cashscript"},"insert":"CashScript"},{"insert":"\nCashScript is a high-level smart contract language for Bitcoin Cash.
