Factom is an Open-Source project that provides a way to build applications on the Bitcoin blockchain.
Factom began by providing proof of existence services, but then moved on to provide proof of existence of transforms. A list of such entries can be thought of as a Factom Chain. Factom can be used to implement private tokens, smart contracts, smart properties, and more.
Factom leverages the Bitcoin Blockchain, but in a way that minimizes the amount of data actually inserted in the Blockchain. Thus it provides a mechanism for creating Bitcoin 2.0 services for the trading of assets, securities, commodities, or other complex applications without increasing blockchain "pollution".
We are very much at an Alpha level of development. We have a demo client and a Factom server prototype which runs against the testnet3 Bitcoin network. Please check the development branch for latest.
