Abstract: Example implementations include a method, apparatus and computer-readable medium for managing augmented reality (AR) effects on a blockchain, comprising receiving a request to convert an AR effect into a decentralized digital asset. The implementations further include uploading an AR effect package comprising execution files of the AR effect to a decentralized server connected to a peer-to-peer network. The implementations further include generating metadata associated with the AR effect package, wherein the metadata indicates attributes of the AR effect and a storage address of the AR effect package in the decentralized server. The implementations further include generating a token universal resource identifier (tokenURI) linked to the metadata and generating, using a smart contract, the decentralized digital asset corresponding to the AR effect package and the tokenURI for storage on the blockchain and subsequent access by a content creation application.

Abstract: Provided in the embodiments of the present disclosure are a method and apparatus for processing an effect video and an electronic device, and a storage medium. The method comprises: obtaining current position information of a target touch point in response to an effect triggering operation; determining, according to the current position information and a drawing parameter, a two-dimensional trajectory effect consistent with a motion trajectory of the target touch point; and displaying, in response to detecting that a three-dimensional display condition is satisfied, a three-dimensional trajectory effect that corresponds to the two-dimensional trajectory effect from a plurality of angles, and stopping displaying the three-dimensional trajectory effect upon the detection of an instruction to stop playing the effect video being satisfied.

Abstract: Example implementations include a method, apparatus and computer-readable medium for decentralized procedural digital asset creation, comprising receiving a first request to create a digital asset from an application executing an augmented reality effect on a computing device, wherein the first request includes an identifier associated with a user of the application. The implementations further include generating the digital asset and metadata of the digital asset, wherein the metadata includes information about characteristics of the digital asset and ownership of the digital asset by the user. Additionally, the implementations further include storing the metadata on a blockchain. Additionally, the implementations further include receiving a second request to access the digital asset from the application. Additionally, the implementations further include transmitting, to the application for rendering, the metadata stored on the blockchain in response to validating the identifier associated with the user in the second request.
