Abstract

A method of tokenization and use of assets, comprising: a) registering at least one asset on a distributed ledger; b) assigning the at least one asset a fungible or non-fungible token with a public key; c) reading information about the at least one asset using a reading device; d) verifying ownership of the at least one asset using a private key which matches the public key; and, e) performing a transaction with the at least one asset.

Claims (26)

1. A method for tagging an asset, comprising:

modifying an asset with a laser beam from a laser system without intentionally using an impurity to create a non-opaque identification etching within the asset using gentle modification with a pulse energy between 10 nJ and 300 nJ, the identification etching having laser-formed “voxels” which are imperceptible at 10× optical magnification but visible to high magnification optical viewing methods; and,

communicating and registering information related to the laser-written identification etching with a distributed ledger.

2. The method of claim 1 , wherein modification of the asset consists of multi-photon absorption by the transparent material.

3. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes operating the laser at a wavelength such that the photon energy is less than the bandgap energy of the material to ensure nonlinear absorption.

4. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes creating the identification etching using a wavelength in the range of 1020-1050 nm or is in the second harmonic wavelength in the range of 510 to 525 nm.

5. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes tagging the asset with a laser using microscope having an objective with a numerical aperture between 0.25 and 1.5 to create the identification etching within the asset.

6. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes modifying the asset using at least one laser pulse to write a voxel making up the identification etching.

7. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes modifying a transparent or translucent stone, a transparent or translucent precious stone, a gem, a crystal, a transparent material, or a translucent material.

8. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes creating a localized two dimensional modification within a depth between 100 microns to 200 microns, or between 200 microns to 500 microns below a surface of the asset.

9. The method claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a three-dimensional pattern of static laser exposures at a depth between 10 microns to 200 microns, or between 200 microns to 500 microns, below a surface of the asset.

10. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern from voxels having a width of less than 1 micron.

11. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern or graphic design.

12. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern indicative of a numerical code, text, a graphic, a logo, or a pattern associated with a particular company.

13. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern indicative of a current physical location or a past physical location of the asset.

14. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern indicative of a current owner or past owner of the asset.

15. The method of claim 1 , wherein modifying the asset with the laser to create the identification etching within the asset includes forming a two-dimensional or three-dimensional pattern indicative of a previous transaction involving grading details or certification details associated with the asset.

16. A tagging system, comprising:

a tagging unit coupled to a laser configured to create a two-dimensional or three-dimensional, non-opaque identification etching using gentle modification without intentionally using an impurity with a pulse energy between 10 nJ and 300 nJ within a transparent or translucent stone, a transparent or translucent precious stone, a gem, a crystal, a transparent material, or a translucent material, formed from voxels that are imperceptible when viewed at a magnification of 10× but visible to high magnification optical viewing methods;

wherein the tagging unit is configured to uploaded information associated with the identification etching, through a communication connection, onto a distributed ledger; and

wherein the information is encrypted upon uploading to the distributed ledger, and

an optical reading device consisting of a more than 10× magnification, asset holder, positioning system, electronic imaging sensor and software interfaced to the distributed ledger.

17. The tagging system of claim 16 , further comprising:

a vision system including an electronic imaging sensor configured to interface with a distributed ledger and exchange information related to the identification etching.

18. The tagging system of claim 16 , wherein the laser is configured to create the two-dimensional or the three-dimensional identification etching within the stone, precious stone, gem, crystal, transparent material, or a translucent material at a depth between 10 microns to 200 microns, or between 200 microns to 500 microns, below a surface using microscope objective having a numerical aperture between 0.25 and 1.5.

19. The tagging system of claim 16 , wherein the two-dimensional or the three-dimensional identification etching comprises a two-dimensional or three-dimensional pattern indicative of a past transaction involving grading details or certification details associated with the stone, precious stone, gem, crystal, transparent material, a translucent material, or a collectible.
