IOTA is an open-source distributed ledger built with the Internet of Things in mind. It can be leveraged for a number of purposes, including messaging with data integrity and feeless microtransactions.

Trinity was initially developed as a community wallet for the IOTA network, to improve the user experience of sending value tokens between different parties. However the Trinity codebase is currently being modularised to allow different components to be easily reused, in order to build other frontend applications that use the IOTA network.
