IOTA IoT Module

IOTA is the outlier among the ISO 20022 coins: it was built for the Internet of Things, the idea that billions of devices need to transact tiny amounts of value and data without paying fees that exceed the transaction value. The IOTA Foundation now describes its focus as digital trade, digital identity, tokenization, and IoT data.

The original Tangle was feeless but relied on a Coordinator node. The May 2025 "Rebased" upgrade removed the Coordinator and moved IOTA to delegated proof of stake over a Move-based object ledger, so modern IOTA is a staked, validator-based network that charges computation and storage fees. The Starfish consensus protocol went live on mainnet on April 23, 2026. (See the Tangle entry for the architecture detail.)

IOTA has no formal ISO 20022 standing that we can source: the IOTA profile found no ISO 20022 conformance statement or payment-rail integration in the Foundation's site, documentation, or blog, which is why the site classifies it as ISO 20022 Adjacent. Its most recent institutional work is trade-focused: the ADAPT program with the AfCFTA Secretariat, the Tony Blair Institute for Global Change and the World Economic Forum, with Kenya, Morocco, and Nigeria chosen as the first countries.
