Abstract: A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The off-chain electronic game is provided by the system with one or more other electronic games. Each of the electronic games are configured to incorporate or integrate the use of on-chain cryptographic assets for in-game leveling and progression. The system implements an interoperability application programming interface (API) that controls usage of an on-chain cryptographic asset between different electronic games. In some examples, the interoperability API permits usage of an on-chain cryptographic asset in only one electronic game in only one point in time. In response to a query by an electronic game that specifies a given asset, the interoperability API can provide a response that indicates that the given asset is already in use in a different game and is not permitted for usage in the electronic game.

Abstract: A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The computer system detects an occurrence of a progression event related to a particular in-game asset associated with a particular player. In response to the occurrence, the computer system increases an upgrade capacity of the particular in-game asset. The upgrade capacity controls a maximum number of attribute upgrades that can be applied to the particular in-game asset at a time. The computer system then permits or prevents application of attribute upgrades to the particular in-game asset based on the upgrade capacity. The computer system further permits or prevents application of attribute upgrades based on whether the attribute upgrades are being applied to other off-chain electronic games. An interoperability API is used to determine whether a given attribute upgrade is being used in another game.

Abstract: A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The off-chain electronic game is configured to incorporate on-chain cryptographic assets related to in-game leveling or progression. In some examples, the on-chain cryptographic assets are non-fungible tokens (NFTs), and the on-chain cryptographic assets define in-game attribute data and can include generic digital and visual art. The computer system obtains permission from an interoperability API of a gaming environment/platform to apply a given on-chain cryptographic asset to an in-game asset to modify attribute data of the in-game asset. The computer system applies the given on-chain cryptographic asset and provides an in-game visual indication of the application and modification of attribute data. The in-game visual indication includes a combination of game-specific digital art and the generic digital art of the given on-chain cryptographic asset.

Abstract: Computer-implemented methods and systems are provided for hosting a location-based virtual environment in which one or more users can participate. Geographic coordinates of the user in real world using data provided by a positioning system may be determined. The real world geographic coordinates of the user may be mapped to virtualized coordinates of an avatar in the virtual environment. The user's real world geographic coordinates may be compared to real world geographic coordinates of one or more entities having a presence in the virtual environment. The user may be presented with options for accepting or activating a first reward from the list of rewards. Responsive to the user selecting the first reward, the first reward may be activated for a first time period in association with one or more goods or services offered by the first entity. The user is rewarded in response to verifying the user has purchased the offered goods or services during the first time period.
