I have proposal for creation of tokens with unique names on the Bittorrent blockchain. If you create one token nobody can create another token with the same name. These tokens can represent different financial instruments like stocks, bonds, futures, options, commodities, fiat currencies, ETFs, mutual funds. Counterparty is similar token project on the Bitcoin blockchain.
These tokens also can have a link to a big file located on BTFS. For example video file. If you want to send this file to another person you just send the token to his wallet. He will click on the link and download the file.
