IOTA is an open-sourcedistributed ledger (cryptocurrency) focused on providing secure communications and payments between machines on the Internet of Things. Using directed acyclic graph (DAG) technology instead of the traditional blockchain, IOTA's transactions are free regardless of the size of the transaction, confirmation times are fast, the number of transactions the system can handle simultaneously is unlimited, and the system can easily scale.[2][3] IOTA was founded in 2015 by David Sønstebø, Sergey Ivancheglo, Dominik Schiener, and Dr. Serguei Popov.[4][5]
Meet IOTA: The Cryptocurrency For The Internet-Of-Things
No Need For Fees
IOTA is based on the idea that the microfees associated with bitcoin and other cryptocurrency transactions that serve to incentivize mining — and transaction validation — will become unfeasible as the number of IoT micropayments skyrocket. Since IOTA requires no mining to validate transactions, transaction fees are unnecessary.
Like Bitcoin, IOTA is a public ledger focused on moving information quickly and cheaply. It’s open-source, so anyone can see the code used to build it. But instead of using a blockchain, IOTA uses an alternative mathematical approach called a directed acyclic graph or “tangle.” According to the IOTA Foundation, a tangle can settle transactions more quickly than blockchains like Bitcoin by processing them “in parallel.” And transactions have no fees, although computational work is required to finalize them. Byteball is another crypto network that uses a directed acyclic graph in lieu of a blockchain.
