Tangle

The Tangle is a distributed ledger technology developed by the IOTA Foundation that replaces the linear blockchain structure with a directed acyclic graph (DAG). Instead of organizing transactions into sequential blocks validated by miners, the Tangle allows each new transaction to directly reference and validate two previous transactions, creating an interconnected web of confirmations. This structure eliminates the need for separate miners and enables scalability without transaction fees, as participants collectively maintain the network by validating transactions as they submit their own. The Tangle's consensus mechanism becomes stronger as more transactions are added, rather than requiring concentrated mining power. Example: The IOTA network uses Tangle technology to enable feeless, scalable microtransactions for Internet of Things (IoT) devices. In 2023, IOTA demonstrated Tangle's practical application in supply chain tracking, allowing thousands of IoT sensors to simultaneously submit data and validate the network without traditional mining infrastructure. Why it matters for blockchain technology: Tangle represents an alternative consensus model addressing blockchain's scalability limitations. Its feeless, asynchronous validation mechanism offers distinct advantages for high-frequency, low-value transactions and IoT applications, expanding blockchain's potential use cases beyond traditional cryptocurrency systems.
