Please refer to Affiliate Disclosure IOTA is a distributed ledger technology (DLT) with an open-source product suite for individuals, businesses, and institutions in Web3. Founded in 2015, it enables low-fee, permissionless value and data transfer on a scalable, decentralized network. As a pioneer in using a Directed Acyclic Graph (DAG) in the DLT and blockchain space, IOTA stands out as one of the first networks to integrate the Move programming language — a language specifically designed for secure and predictable digital asset management. IOTA’s architecture blends a DAG-native consensus mechanism with an object-centric ledger model, enabling advanced programmability through Move smart contracts. Unlike traditional blockchains, IOTA's DAG structure immediately includes transactions into blocks that reference previous blocks. This creates a causal architecture where each new block acknowledges the current ledger state. It removes the need for a shared mempool and eliminates any leader role for block proposals. As a result, IOTA enables low-latency confirmations, high throughput, and parallel block proposals — key features for decentralized finance (DeFi), where fairness and speed are essential, and for supply chain systems that demand scale, traceability, and minimal transaction costs. To learn more about how IOTA works, read our deep dive into DAG architecture and smart contracts . IOTA brings a set of innovations that distinguish it in the crowded field of blockchain and DLT platforms. At its core, the network leverages DAG-based architecture to support parallel transaction processing. This means high throughput and efficient validation without bottlenecks or congested mempools. The absence of miners or validators in the traditional sense also allows for lower fees and a more environmentally sustainable model. One of IOTA’s key differentiators is its integration of the Move programming language, which introduces object-based asset models, predictable smart contract behavior, and inherent security advantages. Combined with its native DAG consensus protocol, IOTA achieves high levels of determinism, making it especially well-suited for financial and real-world asset applications. IOTA’s architecture and execution environment support both Layer 1 and Layer 2 programmability — enabling diverse use cases while maintaining performance. Scalability and Performance – IOTA can support up to 150,000 transactions per second with near-instant finality. The DAG-native consensus protocol linearizes blocks to determine transaction ordering, double-spend resolution, and smart contract execution. Sustainable Tokenomics – IOTA uses Delegated Proof of Stake (DPoS), eliminating the need for energy-intensive mining. A built-in fee-burning mechanism introduces deflationary pressure, supporting long-term sustainability and economic balance. Multi-VM Support – The network uses MoveVM as its primary execution environment for secure smart contract development. A Layer 2 IOTA EVM ensures compatibility with Ethereum’s Solidity-based contracts, enabling seamless migration of existing Web3 dApps to IOTA’s ecosystem.

The IRI (IOTA reference implementation) is open-source Java software that runs on the IOTA Mainnet as well as the Devnet. This software defines the current IOTA protocol, which allows nodes to do the following: Validate transactions Store valid transactions in a ledger Allow clients to interact with the them through a an HTTP API This is beta software, so there may be performance and stability issues. Please report any issues in our issue tracker. To run IRI, you need the following: 4GB RAM 64-bit processor A public IP address that's either static or connected to a dynamic DNS service such as duckdns.org Java Maven Ports 15600 and 14265 must be open After every release, we upload a pre-built Java file onto the GitHub Releases page. If you want to get involved in the community, need help with getting set up, have any issues related to IRI, or just want to discuss IOTA, Distributed Registry Technology (DRT) and IoT with other people, feel free to join our Discord.
