IOTA is a next-generation transaction settlement and data transfer layer designed for the Internet of Things (IoT). Unlike traditional blockchain systems, IOTA utilizes a unique model called "Tangle", which leverages a Directed Acyclic Graph (DAG) structure to enable feeless, scalable microtransactions.
How Does Tangle Work?
1. DAG-Based Mesh Structure
- No Blocks, No Chains: Tangle replaces blockchain’s linear chain with a node network, where transactions are interlinked without cyclic paths.
- Decentralized Validation: Each transaction verifies two previous unconfirmed transactions, eliminating the need for miners.
2. Consensus Mechanism
- User-Driven Validation: Nodes are incentivized to validate others’ transactions to expedite their own confirmations.
- Proof-of-Work (PoW) Light: Users perform minimal computational work to attach transactions to the Tangle.
3. Zero-Fee Model
- No Miner Fees: By distributing validation across users, IOTA removes transaction costs—ideal for IoT micropayments.
FAQs
❓ Is Tangle more scalable than blockchain?
✅ Yes. Tangle’s parallel processing allows higher throughput as more users join.
❓ How secure is Tangle without miners?
✅ Security relies on cumulative PoW from users. Larger networks deter attacks.
❓ Can Tangle support smart contracts?
✅ IOTA’s upcoming upgrades aim to enable programmable features.
