The Factom Protocol

The Factom Protocol is a one of a kind pure data blockchain that makes securing and validating data, building applications, or issuing tokens easy, efficient, secure, and flexible. Thanks to the two token system with fixed input costs, your company or clients can properly budget for usage and don't have to hold cryptocurrency as subscription models can be utilized.

Use With Legacy Systems

Securing and validating the data on your existing legacy systems is easy and efficient with the Factom Protocol. Simply tap into an existing API solution or build your own.

Use The Languages You Already Know

You don't need to learn a new language to build on top of the Factom Protocol. In fact, we have libraries for many of the languages you already utilize:

Factom.js - An interface to factomd API to make it super simple to query, create transactions, chains and entries

Java Enterprise Client Library - Java Library integrates Java (JEE & Spring) with the Factom blockchain

C# / .net Library - The .NET-library supports the complete factomd- and walletd-API.

Python Client Library - Provides Python clients for interacting with the factomd and factom-walletd APIs. The API client is fully tested under Python 2.7, 3.4, 3.5, and 3.6, and likely works with other versions as well.

Rust Client Library - Rust json-rpc client library for communicating with factomd, factom-walletd, debug APIs provided by reference implementation of Factom protocol. Includes examples and wide test coverage.

Haskell Client Library - Haskell json-rpc client library for communicating with factomd, factom-walletd, debug APIs provided by reference implementation of Factom protocol. Includes examples and wide test coverage.

PHP Client Library - PHP json-rpc client library for communicating with factomd, factom-walletd, debug APIs provided by reference implementation of Factom protocol. Includes examples and wide test coverage.

Ruby Client Library - Ruby json-rpc client library for communicating with factomd, factom-walletd, debug APIs provided by reference implementation of Factom protocol. Includes examples and wide test coverage.

Swift client Library - Swift json-rpc client library for communicating with factomd, factom-walletd, debug APIs provided by reference implementation of Factom protocol. Includes examples and wide test coverage.
