11683153, “Blockchain configuration for secure content delivery,” assigned to Disney.
There is provided a method including receiving a playback system identifier corresponding to a playback system, generating a blockchain corresponding to a content identifier identifying a content, wherein the blockchain is uniquely associated with the content identifier, establishing, in the blockchain, a block corresponding to the playback system identifier, sending an encrypted version of the content to the playback system, and in response to one or more updates to the blockchain by the playback system, providing a content encryption key to the playback system for decrypting the encrypted version of the content.
11681509, “Smart contract processing method and system, computer device, and readable storage medium,” assigned to Hangzhou Qulian Technology CO., LTD. (CN).
The present disclosure relates to a smart contract processing method and a system, and a readable storage medium. By segmenting a function requiring performance analysis, establishing a symbol calculation model and calculating a GAS consumption formula, and performing further optimization, a GAS value consumed by the execution of a program containing a polynomial cycle can be automatically calculated, or a GAS value consumed by the execution of a program containing a non-linear cycle can be calculated with minimal human assistance, so as to reflect the performance thereof.
