Abstract: A method of selectively locking a cryptographic digital asset includes instructing or requesting the creation or minting of a plurality of cryptographic tokens via a first common digital contract registered to a distributed ledger. Each cryptographic token is a digital asset that includes at least one attribute that is operative to evolve or change through a plurality of evolutionary stages. The plurality of cryptographic tokens are then instructed to be transferred to a plurality of token holders. The method further includes receiving a request from a token holder to selectively lock their digital asset at one of the plurality of evolutionary stages; and instructing or requesting the transfer of a second cryptographic token to the token holder, the second cryptographic token having at least one attribute that is at least partially derived from the evolutionary stage of the digital asset at the time of the request.

Abstract: An article of footwear customization kit, system, and method include an outsole platform, configured to overlap, at least in part, an outsole of the article of footwear. A lighting unit is configured to be attached to the article of footwear and to be operatively coupled to the outsole platform, the lighting unit comprising a light emitting device configured to be visible exterior to the article of footwear. An adjustable heel unit is configured to be operatively coupled to the outsole platform and the lighting unit, the adjustable heel unit configured to be attached adjacent a heel portion of the article of footwear. The adjustable heel unit comprises a power source configured to provide power to the light emitting device when the adjustable heel unit is operatively coupled to the lighting unit. The adjustable heel unit is configured to be movable relative to the article of footwear.
