description: IOTA is an open-source distributed ledger technology built to bring real-world applications on-chain. It is the
  first internet-scale programmable blockchain platform powered by the Move programming language with horizontal scaling,
  feeless transactions, and a unique parallel transaction processing model. IOTA exposes a JSON-RPC 2.0 API over HTTP and
  a GraphQL RPC for querying objects, checkpoints, transactions, coins, events, and on-chain state on Mainnet, Testnet, and
  Devnet networks. The platform targets trade and supply chains, decentralized finance, digital identity, real-world asset
  tokenization, and product lifecycle management.
