Tangle is the underlying technology of the cryptocurrency IOTA. IOTA's Tangle is a directed acyclic graph (DAG) based distributed ledger technology that is different from the traditional blockchain technology used by most cryptocurrencies. In the Tangle, each transaction must confirm two previous transactions, thus forming a network of transactions that is self-verifying. This allows for faster and more efficient transactions, as well as the ability to handle a larger number of transactions per second. IOTA's Tangle is designed to be scalable and is intended to support the Internet of Things (IoT) ecosystem. It has been proposed as a potential solution for micropayments, data integrity, and secure machine-to-machine communication. IOTA (MIOTA) is the native cryptocurrency of the IOTA network. It is currently valued at around $1.5 per coin, with a market capitalization of around $4.5 billion. As with any other crypto, it is highly volatile, and its value can fluctuate greatly.
