Registering Bitmark Certificates

Assets with titles that have been publicly recorded are more valuable than those without. They are what grant basic rights, such as the ability to resell, rent, lend, and donate the property. The Bitmark blockchain allows individuals to access these rights for digital assets by registering their titles as Bitmark Certificates. This can be done using the Bitmark SDK, or the Bitmark CLI.

The process of registering a Bitmark Certificate for a digital asset occurs in two steps:

  • Registering the asset: this creates an Asset Record, which is stored on the Bitmark blockchain.

  • Issuing bitmarks: this creates Issue Records linking to the corresponding asset record, which are also stored on the Bitmark blockchain.

This process registers legal property rights on the public Bitmark blockchain for an individual’s digital assets, including personal health and social data, creative works such as art, photography, and music, and other intellectual property. These legal rights determine who owns property and what can be done with it, whether the individual wants to keep it, sell it, or donate it.


Any user who want to interact with the Bitmark Property System must have a Bitmark Account. Please refer to the Bitmark Account section for instructions on creating a new Bitmark Account.

Registering Bitmark Certificates using the Bitmark SDK

To register a new property using the Bitmark JS SDK:

  • Configure the SDK and create an account
  • Register an asset

      // Create a Bitmark Account as the Issuer
      let account = new sdk.Account();
      // Define the asset name & metadata
      let name = "Example asset";
      let metadata = {"Example key":"Example alue"};
      // Build and sign the asset registration request
      let params = sdk.Asset.newRegistrationParams(name, metadata);
      await params.setFingerprint(filepath);
      // Send the request
      let assets = (await sdk.Asset.register(params)).assets;
      let assetId = assets[0].id;
  • Issue the first Bitmark Certificate

      // Build and sign the bitmark issuance request
      let issueParams = sdk.Bitmark.newIssuanceParams(assetId, 1);
      // Send the request
      let bitmarks = (await sdk.Bitmark.issue(issueParams)).bitmarks;
      let bitmarkId = bitmarks[0].id;
  • Verify the issuance transaction by querying for the Bitmark by its bitmarkId

          await Bitmark.get(bitmarkId);

Registering Bitmark Certificates using the Bitmark CLI

See The Basics of Bitmark CLI for more information on the interface.

To register a new property using the Bitmark CLI:

  • Compute the hash of an asset

      $ bitmark-cli -n <network> \
      fingerprint -f <file>

    The fingerprint command computes the hash of a file

    Command Options:

    • file - The file from which the hash is computed.


      $ bitmark-cli -n testing \
      fingerprint -f test.txt
          "file_name": "filename.test",
          "fingerprint": "0122aa7d05ce9d324feca37780eeeeb7af8611eefb61cfe42bf9f8127071b481520b529e06c9f0799c7527859361f1694acef106d5131a96641eae524e1c323500"
  • Issue the first Bitmark Certificate

      $ bitmark-cli -n <network> -i <identity> \
      create -a '<asset name>' \
      -m '<asset metadata>' \
      -f <asset fingerprint> \

    The create command registers an asset from a fingerprint and issues the corresponding bitmarks

    Global Options:

    • identity - The identity of the registrant’s Bitmark Account, which is stored in the Bitmark CLI config file.

    Command Options:

    • asset name - The name field in the asset record.

    • asset metadata - The metadata field in the asset record.

    • asset fingerprint - The hash of the asset.

    • -z option - This is the first Bitmark issued for the asset.


      $ bitmark-cli -n testing -i first \
      create -a 'Example asset' \
      -m 'Key1\u0000Value1\u0000Key2\u0000Value2' \
      -f 0122aa7d05ce9d324feca37780eeeeb7af8611eefb61cfe42bf9f8127071b481520b529e06c9f0799c7527859361f1694acef106d5131a96641eae524e1c323500 \
          "assetId": "dac17bef505f7a5acf890a1d0f232b7d847f1e951cf1f5b880de13253a10df43cdbcab553e08050808e0b3fdfd2581a798dcdf9cedbbddf4476ead14caa612d3",

          "submittedNonce": "00000001a67fa973",
          "proofStatus": "Accepted"
  • Verify the status of the Bitmark issuance transaction

      $ bitmark-cli -n <network>\
        status -t <txid>

    The status commands checks if a Bitmark has been issued

    Command Options:

    • txid — The transaction being verified, corresponding to the issueIds from the create command


    • Pending - Not paid.

    • Verified - Paid but not confirmed on the blockchain.

    • Confirmed - Confirmed on the blockchain.


      $ bitmark-cli -n testing \
        status -t \
      // Check right after the create command
        "status": "Pending"
      // Check again after some minutes
        "status": "Confirmed"
