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 move 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".
