Tangle is a unique data structure used in certain blockchain alternatives, particularly IOTA. Unlike traditional blockchains that rely on a linear chain of blocks, Tangle employs a directed acyclic graph (DAG). In this system, each transaction confirms two previous transactions, creating a web of interconnected transactions.This structure allows for greater scalability and faster transaction speeds since multiple transactions can be processed simultaneously. There is no need for miners, as every participant contributes to the network by validating transactions. As a result, users can send and receive transactions without incurring fees.Tangle aims to address issues such as network congestion and high transaction costs, making it suitable for applications in the Internet of Things (IoT), where devices require real-time data communication. The design of Tangle gives it the potential to support a large volume of transactions efficiently, providing an innovative solution for decentralized systems.
