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.

First claim

What is claimed is:

1. A method for managing augmented reality (AR) effects on a blockchain, comprising:
receiving a request to convert an AR effect into a decentralized digital asset;
uploading an AR effect package comprising execution files of the AR effect to a decentralized server connected to a peer-to-peer network;
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;
generating a token universal resource identifier (tokenURI) linked to the metadata;
generating, using a smart contract, the decentralized digital asset corresponding to the AR effect package and the tokenURI, wherein the smart contract assigns ownership of the decentralized digital asset to a creator of the AR effect package;
storing, on the blockchain, a creation event including generation information of the decentralized digital asset;
receiving a user request from a content creation application to access the AR effect package, wherein the user request comprises the tokenURI;
enabling, using the smart contract, the access to the AR effect package by the content creation application;
receiving another user request from a different content creation application to access the AR effect package, wherein the another user request comprises the tokenURI; and
enabling, using the smart contract, the access to the AR effect package to the different content creation application.

2. The method of claim 1 , wherein assigning the ownership of the decentralized digital asset to the creator of the AR effect package comprises linking the decentralized digital asset to a wallet address of the creator.

3. The method of claim 1 , wherein the user request further comprises a wallet address of a user of the content creation application, and wherein enabling the access to the AR effect package to the content creation application comprises:
transferring the ownership of the decentralized digital asset from the creator to the user by linking the decentralized digital asset to the wallet address of the user.

4. The method of claim 3 , further comprising:
storing, on the blockchain, an ownership change event including a wallet address of the creator, the wallet address of the user, and the tokenURI.

5. The method of claim 1 , wherein the content creation application is configured to:
download the AR effect package from the decentralized server to a computing device executing the content creation application;
decode the AR effect package to render the AR effect; and
enable access to the AR effect by a user of the content creation application.

6. The method of claim 1 , wherein the AR effect package is a folder that includes one or more of visuals, scripts, and configuration files of the AR effect.

7. An apparatus for managing augmented reality (AR) effects on a blockchain, comprising:
a memory; and
a processor communicatively coupled with the memory and configured to:
receive a request to convert an AR effect into a decentralized digital asset;
upload an AR effect package comprising execution files of the AR effect to a decentralized server connected to a peer-to-peer network;
generate 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;
generate a token universal resource identifier (tokenURI) linked to the metadata;
generate, using a smart contract, the decentralized digital asset corresponding to the AR effect package and the tokenURI, wherein the smart contract assigns ownership of the decentralized digital asset to a creator of the AR effect package;
store, on the blockchain, a creation event including generation information of the decentralized digital asset;
receive a user request from a content creation application to access the AR effect package, wherein the user request comprises the tokenURI;
enable, using the smart contract, the access to the AR effect package by the content creation application;
receive another user request from a different content creation application to access the AR effect package, wherein the another user request comprises the tokenURI; and
enable, using the smart contract, the access to the AR effect package to the different content creation application.

8. The apparatus of claim 7 , wherein to assign the ownership of the decentralized digital asset to the creator of the AR effect package comprises to link the decentralized digital asset to a wallet address of the creator.

9. The apparatus of claim 7 , wherein the user request further comprises a wallet address of a user of the content creation application, and wherein to enable the access to the AR effect package to the content creation application comprises to:
transfer the ownership of the decentralized digital asset from the creator to the user by linking the decentralized digital asset to the wallet address of the user.

10. The apparatus of claim 9 , wherein the processor is further configured to:
store, on the blockchain, an ownership change event including a wallet address of the creator, the wallet address of the user, and the tokenURI.

11. The apparatus of claim 7 , wherein the content creation application is configured to:
download the AR effect package from the decentralized server to a compute device executing the content creation application;
decode the AR effect package to render the AR effect; and
enable access to the AR effect by a user of the content creation application.

12. The apparatus of claim 7 , wherein the AR effect package is a folder that includes one or more of visuals, scripts, and configuration files of the AR effect.

13. A non-transitory computer-readable medium having instructions stored thereon for managing augmented reality (AR) effects on a blockchain, wherein the instructions are executable by a processor to:
receive a request to convert an AR effect into a decentralized digital asset;
upload an AR effect package comprising execution files of the AR effect to a decentralized server connected to a peer-to-peer network;
generate 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;
generate a token universal resource identifier (tokenURI) linked to the metadata;
generate, using a smart contract, the decentralized digital asset corresponding to the AR effect package and the tokenURI, wherein the smart contract assigns ownership of the decentralized digital asset to a creator of the AR effect package;
store, on the blockchain, a creation event including generation information of the decentralized digital asset;
receive a user request from a content creation application to access the AR effect package, wherein the user request comprises the tokenURI;
enable, using the smart contract, the access to the AR effect package by the content creation application;
receive another user request from a different content creation application to access the AR effect package, wherein the another user request comprises the tokenURI; and
enable, using the smart contract, the access to the AR effect package to the different content creation application.

14. The non-transitory computer-readable medium of claim 13 , wherein to assign the ownership of the decentralized digital asset to the creator of the AR effect package comprises to link the decentralized digital asset to a wallet address of the creator.

15. The non-transitory
