Restricted assets work in tandem with tags, also known as ‘qualifier assets’. These are assets that you use to tag addresses. Tagged addresses are allowed to receive and send a restricted assets tied to the tag. To use restricted assets with tags, you will need to issue a qualifier asset, a main asset, and a restricted asset. The total cost to make a working restricted asset with tags costs 3000 RVN + some miner fees; 1000 for the qualifier asset, 500 for a main asset, and 1500 for a restricted asset. Tagging an address costs 0.1 RVN per tag. These coins are burned and will be removed from the available supply forever. So, by issuing assets, you make the rest of the available RVN a tiny bit more scarce.
