TRON is a decentralized, open-source blockchain-based operating system with smart contract functionality, proof-of-stake principles as its consensus algorithm and a cryptocurrency native to the system, known as Tronix (TRX). It was established in March 2014 by Justin Sun and since 2017 has been overseen and supervised by the TRON Foundation, a non-profit organization in Singapore, established in the same year. It was originally an Ethereum-based ERC-20 token, which switched its protocol to its own blockchain in 2018. TRC20 has a fee of 5 trones per 1 USDT coin for the transfer. From Wikipedia
