The system is configured to generate a digital token and cryptographically link the digital token to on a blockchain to facilitate transactions for the item using the blockchain. The system includes a video game integration system that serves an electronic advertisement corresponding to the real-world item to a video game that includes a visual indicum of the token; receives a notification indicating that a user has transacted for the real-world item via the video game; and initiates an assignment of the digital token to an account of the user on the blockchain, such that ownership data of the digital token is updated to reflect that the user is an owner of the digital token, such that the user may redeem the token to take possession of the item. ## Claims ### Claim 1 A system for facilitating transactions for real-world items in video games using digital tokens, comprising: an item management system that is configured to: provide an interface that receives a set of real-world item attributes of an item; generate a virtual representation of the real-world item based on the set of real-world item attributes, the virtual representation being a data structure that includes the set of real-world item attributes; a token generation system configured to: generate a digital token that has a set of digital attributes that correspond to the set of real-world item attributes, wherein the digital token is cryptographically secure, and the set of digital attributes includes a token identifier that identifies the digital token; and generate a cryptographically secure, one-to-at-least-one link between the digital token generated by the token generation system and the virtual representation of the real-world item, such that the digital token provides a digital representation of the real-world item and is redeemable by a verified owner of the digital token for a unique unit of the real-world item via a graphical user interface of a digital wallet application such that the verified owner of the digital token takes possession of the real-world item; a ledger update system configured to write the digital token to a blockchain in accordance with a protocol, thereby facilitating transactions for the real-world item using the digital token; a video game integration system configured to: handle a request from a video game instance of a video game being executed by a user device associated with a user; serve an electronic advertisement corresponding to the real-world item to the video game instance, wherein the advertisement includes a visual indicum that is indicative of the digital token; receive a transaction notification indicating that the user has transacted for the real-world item via the video game instance; and initiate an assignment of the digital token to an account of the user on the blockchain, such that ownership data of the digital token is updated to reflect that the user is an owner of the digital token; and a redemption system that facilitates redemption of digital tokens, the redemption system being configured to: receive a redemption request that indicates the token identifier of the digital token and an account identifier that indicates a public address of a redeeming user; and initiate fulfillment of the unique unit of the real-world item in response to verifying that the digital token is owned by the redeeming user based on the token identifier, the public address, and the blockchain. ### Claim 2 (depends on 1) The system of claim 1, wherein the digital token is a non-fungible token that corresponds to a unique unit of the real-world item, such that the digital token is redeemable for the unique unit of the real-world item. ### Claim 3 (depends on 1) The system of claim 1, wherein the real-world item is a fungible consumer product and the digital token is a copy of a fungible token that is redeemable for a unit of a plurality of units of the fungible consumer good, such that multiple users may redeem respective other copies of the fungible token for respective units of the plurality of units of the fungible consumer product. ### Claim 4 (depends on 1) The system of claim 1, wherein the real-world item is a consumer product and the digital token is cryptographically linked with the virtual representation of the consumer product and is redeemable for a unit of the consumer product. ### Claim 5 (depends on 1) The system of claim 1, wherein the real-world item is a gift card and the digital token is cryptographically linked with the virtual representation of the gift card and is redeemable for the gift card. ### Claim 6 (depends on 1) The system of claim 1, wherein the real-world item is a food item and the digital token is cryptographically linked with the virtual representation of the food item, and wherein redeeming the token initiates delivery of the food item to the user. ### Claim 7 (depends on 1) The system of claim 1, wherein the digital token is transferrable to another user. ### Claim 8 (depends on 1) The method of claim 1, wherein the real-world item has a defined type and a defined set of characteristics but is not yet in existence, such that the digital token is redeemable for the real-world item after the real-world item is in existence. ### Claim 9 (depends on 6) The system of claim 6, further comprising: a token transfer system that receives a request to transfer the digital token from the account of the user to a second account of the other user and, in response, facilitates the transfer of the digital token from the account of the user to the second account of the user via the ledger update system. ### Claim 10 (depends on 1) The system of claim 1, wherein once the digital token is assigned to the account of the user, the digital token unlocks an in-game benefit to the user in the video game instance of the video game. ### Claim 11 (depends on 10) The system of claim 10, wherein once the digital token is transferred to a second account of another user, the in-game benefits are unlocked with respect to video game instances of the other user. ### Claim 12 (depends on 10) The system of claim 10, wherein once the digital token is transferred to a second account of another user, the in-game benefits are no longer unlocked with respect to video game instances of the user. ### Claim 13 (depends on 1) The system of claim 1, wherein the real-world item is already in existence. ### Claim 14 (depends on 1) The system of claim 1, wherein the set of real-world-item attributes includes a set of physical attributes of the real-world item, wherein at least some of the digital attributes are based on the physical attributes of the real-world item. ### Claim 15 (depends on 1) The system of claim 1, wherein the set of real-world-item attributes include a set of origination attributes of the real-world item, wherein at least some of the digital attributes are based on the origination attributes of the real-world item. ### Claim 16 (depends on 15) The system of claim 15, wherein the set of origination attributes includes one or more of limited-edition attributes, celebrity signature attributes, certification of originality attributes, location of origin attributes, or certification of ethical production attributes. ### Claim 17 (depends on 1) The system of claim 1, wherein the set of digital
