TAG Protocol is a DAO (Digital Autonomous Organization) that operates Hashtag registration, subscription, and trading services on the Binance smart chain. Users can register and permanently own unique social media tags, just like they register and own domain names, and use them to mine Tagcoin (local protocol currency) by participating in the daily tag pledge pool. Users can immediately exchange Tagcoin into other Cryptocurrency, such as BNB and BUSD, at the market price on Tag Exchange. Users can also trade Hashtags with other users in the Hashtag auction market in exchange for other Cryptocurrency.
