Systems and methods for determining authenticity of non-fungible digital assets

1. A method for determining authenticity of digital assets including non-fungible digital assets, the method comprising:

storing information in electronic storage, wherein the stored information includes information regarding a given type of digital assets, wherein an implementation of the given type of digital assets includes a smart contract on a decentralized database, wherein the smart contract is associated with a keypair of cryptographic keys including a public key and a private key, wherein the digital assets include a first digital asset of the given type, wherein the first digital asset is associated with metadata specific to the first digital asset, wherein the metadata includes a first part and a second part;

generating a digital signature of a first quantity of information, wherein the first quantity of information is based on at least one or (i) an identifier of the smart contract, and/or (ii) an asset-specific identifier that identifies the first digital asset, wherein generation of the digital signature is based on the keypair of cryptographic keys associated with the smart contract;

recording, on the decentralized database, the digital signature in the first part of the metadata of the first digital asset;

storing the second part of the metadata of the first digital asset in external electronic storage that is external to the decentralized database; and

recording, on the decentralized database, a Uniform Resource Locator (URL) that refers to a location of the second part of the metadata as stored in the external electronic storage, wherein the URL is recorded in the first part of the metadata of the first digital asset.

2. The method of claim 1 , wherein the first quantity of information includes encoded information.

3. The method of claim 2 , wherein the encoded information has been generated using base64 encoding.

4. The method of claim 1 , wherein a limited number of the digital assets represent admission tickets to a show or concert.

5. The method of claim 1 , wherein a limited number of the digital assets represent in-game assets that are usable within an online gaming platform.

6. The method of claim 1 , wherein recording the digital signature includes creating an image that visually depicts the digital signature and recording the image as part of the metadata of the first digital asset.

7. The method of claim 6 , wherein a uniform resource locator (URL) that locates the image is recorded on the decentralized database, and wherein the image is not recorded on the decentralized database.

8. The method of claim 1 , wherein the first quantity of information is hashed using a hashing function prior to the generation of the digital signature.

9. A method for determining authenticity of digital assets including non-fungible digital assets, the method comprising:

obtaining an identifier of a smart contract, wherein an implementation of a given type of digital assets includes a smart contract that is recorded on a decentralized database, wherein the smart contract is associated with a keypair of cryptographic keys including a public key and a private key, wherein the digital assets include a first digital asset;

obtaining metadata that is specific to the first digital asset, wherein the metadata includes a first part and a second part, wherein the first part has been recorded on the decentralized database, wherein the second part has been stored in external electronic storage that is external to the decentralized database, wherein the first part of the metadata includes a Uniform Resource Locator (URL) that refers to a location of the second part of the metadata as stored in the external electronic storage;

extracting a digital signature and a first quantity of information from the first part of the metadata; and

verifying whether the digital signature corresponds to the first quantity of information, wherein verification is based on the keypair of cryptographic keys.

10. The method of claim 9 , further comprising:

generating a quantity of decoded information based on decoding the first quantity of information.

11. The method of claim 10 , wherein the decoding used to generate the quantity of decoded information is base64 decoding.

12. The method of claim 10 , further comprising:

verifying whether the quantity of decoded information includes the identifier of the smart contract.

13. The method of claim 10 , further comprising:

verifying whether the quantity of decoded information includes an asset-specific identifier that identifies the first digital asset.

14. The method of claim 9 , wherein a limited number of digital assets represent admission tickets to a show or concert.

15. The method of claim 9 , wherein a limited number of digital assets represent in-game assets that are usable within an online gaming platform.

16. A system configured to determine authenticity of digital assets including non-fungible digital assets, the system comprising:

electronic storage configured to electronically store information, wherein the stored information includes information regarding a given type of digital assets, wherein an implementation of the given type of digital assets includes a smart contract on a decentralized database, wherein the smart contract is associated with a keypair of cryptographic keys including a public key and a private key, wherein the digital assets include a first digital asset of the given type, wherein the first digital asset is associated with metadata specific to the first digital asset, wherein the metadata includes a first part and a second part; and

one or more hardware processors configured via machine-readable instructions to:

generate a digital signature of a first quantity of information, wherein the first quantity of information is based on at least one or (i) an identifier of the smart contract, and/or (ii) an asset-specific identifier that identifies the first digital asset, wherein generation of the digital signature is based on the keypair of cryptographic keys associated with the smart contract;

record, on the decentralized database, the digital signature in the first part of the metadata of the first digital asset;

store the second part of the metadata of the first digital asset in external electronic storage that is external to the decentralized database; and

record a Uniform Resource Locator (URL) that refers to a location of the second part of the metadata as stored in the external electronic storage, wherein the URL is recorded in the first part of the metadata of the first digital asset.
