What is tangle in IOTA?

Tangle uses a proof-of-work (PoW) system for authenticating transactions on a distributed ledger . Tangle’s PoW system is similar to the one used by bitcoin, but it uses less energy and takes less time than other PoW systems (including the one used by bitcoin).

The Tangle is the moniker used to describe IOTAs directed acyclic graph (DAG) transaction settlement and data integrity layer . It is structured as a string of individual transactions that are interlinked to each other and stored through a network of node participants.

Selling data or resources also requires the possibility of sending very small transactions. Cryptocurrencies using Blockchain are unable to resolve these issues, and most of other active cryptocurrencies use this technology. In order to mitigate these issues , Iota created its own DLT, which is called Tangle.

Tangle is a technology that is used for cryptocurrency transactions like Blockchain . Here, a directed acyclic graph (DAG) is used, which resembles a distributed ledger. DAG is not under the control of any external authority such as a bank or any financial institution.
