Tron

TRX, the native coin of TRON, the blockchain that carries the largest share of the world's USDT transfers and works in practice as a dollar payments rail. TRX pays the fees on those transfers, and staking it for bandwidth and energy lets a holder move USDT repeatedly without spending coins each time. Staked TRX also secures the chain and votes for its block producers. It was launched in 2017 by Justin Sun.
