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 — and an ideal footprint for the ever-expanding Internet of Things ecosystem. Because there’s no blockchain, there are no miners, and because there are no miners, there are no fees. Many established networks see costs balloon when congestion intensifies, but IOTA aims to provide limitless throughput at minimal expense.
