How it Works
  1. A digital signature of your file (a hash) is created client-side (we never store your file)
  2. The hash is added to the Factom blockchain
  3. A merkle root from the hash is entered in the Bitcoin blockchain
  4. We email you the hash and its location in Factom and Bitcoin. You now have a timestamped fingerprint of the file in Factom and Bitcoin, forever
  1. Your file is hashed again
  2. The hash is checked against the Factom blockchain
  3. Confirmation of a match is emailed to you along with its location in both Factom and Bitcoin
  4. You now have cryptographic (and legally enforceable) proof that your file existed in exactly that form, at that point in time
