ixo is the blockchain for impact, helping individuals and organizations around the world to achieve the UN Sustainable Development Goals by 2030. It gives everyone the power to deliver, evaluate, and invest in sustainable social, environmental, and economic development.

Herman Smith explains how ixo enables all measurable changes to be transformed into verified impact data with cryptoeconomic proof of impact by using blockchain technologies and Web 3.0 standards. This is recorded in real time in an ecosystem that is owned by everyone.

Anyone can register as a member on the ixo.world site and, after passing know your customer (KYC), create projects or become a service provider on existing projects. Project funding takes place by means of ixo ERC20 tokens on the Ethereum network. The entire project is open source, leveraging Tendermint for its Byzantine-fault tolerant state machine replication (or blockchain, for short). User interaction with the blockchain takes place from a React-native mobile application and a web-based distributed app (DApp) where interactions are cryptographically signed by the end user using the private key associated with their Sovrin distributed identifier (DID) by means of a browser extension.

Further interesting aspects of the project include off-chain data storage by means of Elysian, which is a project data store (PDS) allowing third party project creators to be in charge of their own data and where it lives. The ixo stack includes AWS, Docker, JavaScript, TypeScript, MongoDB, Ethereum Smart Contracts, Cosmos, Tendermint, and LevelDB.
