Factom is a BaaS (Blockchain-as-a-Service) database built on top of the Bitcoin blockchain. It provides a data layer that leverages the blockchain to timestamp and store a variety of records, including medical records, voting systems, and real-world contracts. The Factom Foundation is responsible for protocol development and offers two record management products. The first, Harmony, is a service that stores the documentation of mortgage-backed securities. The second, sLoc, is a physical document verification service offered through a strategic partnership with SMARTRAC, a developer, manufacturer and supplier of Radio-Frequency Identification (RFID) systems. sLoc enables users to apply RFID stickers with unique identifiers to physical documents, such as land titles, birth certificates and public records. The unique hash, along with the ownership data, is then stored in a blockchain database.
