Tangle

Tangle is a distributed ledger technology designed for the Internet of Things (IoT) devices. It is a Directed Acyclic Graph (DAG) based system that is fundamentally different from blockchain technology. Instead of using miners to validate transactions, Tangle uses a consensus mechanism called the "Coordinator" to manage the network's security and stability.

In Tangle, every transaction is a "tip" and is validated by approving two previous transactions, forming a web of interconnected transactions. This means that transactions can be processed simultaneously, and the network's throughput increases as more transactions are added to the web. This property makes Tangle a promising solution for applications that require high scalability.

Tangle is also designed to be feeless, which means that users don't have to pay transaction fees, making it ideal for microtransactions. However, the "Coordinator" mechanism is a central point of control, making it a potential target for attacks. This has led to some criticisms of Tangle's security.

Despite these limitations, Tangle has shown potential in various use cases, such as supply chain management, identity verification, and decentralized marketplaces. Its unique approach to consensus and scalability makes it a viable alternative to traditional blockchain technology in certain scenarios.

If you're looking for a distributed ledger technology that is designed specifically for IoT devices, Tangle may be a good option to consider. Its DAG-based system, feeless transactions, and potential for scalability make it an innovative solution for various use cases.
