IOTA is a rather unique project that aims to implement the concept of Internet of Things. IOTA offers not only quick payments, but also small ones. Small, tiny transactions that are not reasonable and efficient to make with Bitcoin and many other cryptocurrencies. In addition, IOTA seeks to integrate all smart devices, from radars on roads and smart houses, to gadgets and microwave ovens within a single network. The security of this network is based on a distributed ledger technology that has no blocks, a “blockless blockchain” — Tangle.
