Making use of a distributed blockchain ledger, the inventors, Andon, Davis, Pham and Schroeder, allow for the creation, protection, tracking, authentication and sales of not only a physical pair of shoes but the digital representation as well. And it is this "digital asset" that may spawn offspring.
From the '726 patent, "Owners of cryptographic digital assets may wish to intermingle or “breed” their digital assets with other digital assets to create asset “offspring,” such as schematically shown in FIG. 6. A first digital asset owner and a second digital asset owner may wish to collaborate and crossbreed their digital assets 82, 84 in order to create a new cryptographic digital asset. The first owner may be set as a “primary artist” if his/her digital asset has attributes desired by the second owner. In this instance, the second owner may initiate a smart contract with the first owner to collaborate. One or both parties may fund the contract with physical or digital currency, e.g., to pay for the transfer, a “collab fee” set by the breeding host site, and an optional siring fee for the second owner's siring services. Once both parties agree to and sign the breeding contract, one or both parties may be prompted to select one or more traits from their “parent” digital asset to transfer to the resultant “progeny” digital asset. Alternatively, the breeding host site may employ a breeding algorithm to build a new digital asset from two or more preexisting digital assets."
Further. "A “Collab Science” Algorithm may be employed to determine which contributing cryptographic digital asset will be designated as the sire, determine which contributing cryptographic digital asset will be designated as the dam, and determine which code subsets from each parent asset will be employed to build the cryptographic token key for the resultant digital asset."
