Smart contracts, blockchains (distributed ledgers), and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to ANT, the first patent addresses techniques for deploying a smart contract. Assigned to NIKE, the second patent addresses techniques for video game integration of cryptographically secured digital assets.

Abstract
Implementations of the present specification provide a method for deploying a smart contract. According to one implementation the method includes: receiving a transaction request for invoking a first contract; obtaining a first instruction code and a function index table, wherein the function index table is used to indicate a memory address of an instruction code corresponding to each of import and export functions in the first contract; determining a first memory address corresponding to the invocation function based on the function index table; and executing the first instruction code in the first memory address based on the determined first memory address.

Abstract
A method of integrating a cryptographically secured digital asset into a digital video game application includes receiving a digital asset identification (ID) code representative of cryptographically secure digital asset. The digital asset ID code exists together with a unique owner ID code on a distributed blockchain ledger, and includes a code string segmented into a series of code subsets. A first plurality of the code subsets includes data indicative of a plurality of attributes of the digital asset. The digital asset ID code is provided to a virtual object generator, which returns a virtual object constructed from the first plurality of the code subsets of the unique owner ID code, and where the virtual object further including a plurality of object attributes. At least one of the character attributes is then modified according to at least one of the object attributes.
