Originally launched simply as VeChain (VEN) in 2015 as a blockchain designed for industrial supply chain applications, in 2018 it was modified and rebranded as VeChainThor (VET). Unusually, the VeChainThor ecosystem is powered by two tokens - VET (Smart Money) and VTHO (Energy). This is intended to separate the cost of using the blockchain from speculation-fuelled market volatility.
