IOTA is a distributed ledger with one big difference: it isn’t actually a blockchain. Instead, its proprietary technology is known as Tangle, a system of nodes that confirm transactions. The foundation behind this platform says this offers far greater speeds than conventional blockchains

IoTeX has built a decentralized platform whose aim is to empower the open economics for machines — an open ecosystem where people and machines can interact with guaranteed trust, free will, and under properly designed economic incentives.
