IOTA is a digital currency that seeks to be the internet of things’ backbone. Its design is described as post-blockchain. While IOTA is comparable to many blockchain projects, it does not use blocks or a single, linear chain in its construction. Instead, it is built on the Directed Acyclic Graph notion. While it is not a blockchain, its distributed ledger is a public, permissionless ledger. It has several advantages over standard blockchains due to its unique structure.
Dominik Schiener, David Snsteb, Sergey Ivancheglo, and Dr. Serguei Popov conceived IOTA in 2014 and formed it in 2015. When many of the founders were working on a hardware firm with an IoT focus, they realised that current IoT payment alternatives were limited. IOTA was established as a response to these issues. The network itself creates a structure of nodes and interactions as a result of the combination of all three of these qualities. These qualities can be mathematically demonstrated, allowing the network to construct a loosely organised transaction ordering and avoid duplicate spends without the use of dedicated miners, blocks, or a single chain.

IOTA does not distinguish between nodes and miners, instead, any node that makes a transaction must also confirm two prior transactions by executing a tiny proof-of-work. The terms users and miners are interchangeable. The nodes in the graph are users, while the edges represent confirmations of prior transactions. While IOTA transactions do not need users to pay any fees, the modest proof-of-work serves the same anti-Sybil attack function as fees in other systems.
When a user wants to create a new transaction in IOTA, they must first sign the transaction inputs using their private key. The wallet then selects two tips for them to confirm using a Markov Chain Monte Carlo selection process. Two distinct transactions may confirm the same tip since not every node has the same tangle state at all times. Although the MCMC is not enforced at the protocol level, the IOTA team has published research on Tangle equilibria even when selfish tip selection is present.
