[0060] The digital wallet module assigns a unique on-chain address as an account to registered users of gig service providers, and also assigns a local key for logging into the platform and a subject key for managing on-chain information.

[0061] The digital wallet module uses a two-layer architecture of principal key and local key to create the digital identity of users of the gig economy platform; users use local keys to enter the gig economy service platform; users use principal keys to bind user digital attribute proof.

[0062] The subject key is the public and private key of the digital identity built based on digital signature technology, corresponding to the on-chain address of the digital identity, and carries all digital assets corresponding to the on-chain address. The algorithms supported by the subject key include the Internet signature algorithm and the blockchain signature algorithm.

[0063] The local key is the public and private key of the client built based on digital signature technology. It is generated when the user logs in to a new environment. The local key is used for daily operations and cannot be exported. It needs to be used with the authorization issued by the subject key and the authorization is unlocked when logging in.

[0064] The digital wallet module implements transaction verification function through signature verification technology.

[0065] The digital wallet module implements the on-chain social recovery function based on the domain name key identification email authentication mechanism. The recovery process includes: the subject key authorizes the registered email address and encrypted will, and the encrypted will and the target address of the digital asset are broadcast on the chain in the format through the registered email address. The on-chain contract verifies the DKIM signature and encrypted will of the email. After the verification is passed, the on-chain contract authorizes the transfer of digital assets.

[0066] Specifically, the digital wallet module uses a two-layer architecture of MasterKey (subject key) and LocalKey (local key) to create the digital identity of users of the gig economy platform. Users use LocalKey to enter the gig economy service platform and use MasterKey to bind digital attribute certificates such as user affiliation and qualifications.

[0067] MasterKey is the public and private key of a digital identity built based on digital signature technology. It corresponds to the on-chain address of the digital identity and carries all digital assets corresponding to the on-chain address. Supported algorithms include but are not limited to commonly used Internet signature algorithms such as RSA and Secp256r1, as well as commonly used blockchain signature algorithms such as Secp256k1, Ed25519, and Secp256r1.

[0068] LocalKey is the public and private key of the client built based on digital signature technology. It is generated when the user logs in to a new environment. It is used for daily operations and cannot be exported. It needs to be used with the authorization issued by MasterKey. After the authorization is unlocked during login, only LocalKey and authorization exist locally. Signature algorithms such as RSA and Secp256r1 are supported.

[0069] The digital wallet module can realize the transaction verification function through the signature verification technology. The verification content includes the authorization signature of the MasterKey public key and MasterKey-privKey (subject private key) to the LocalKey-pubKey (local public key), as well as the LocalKey public key and LocalKey's signature on the transaction.

The recovery process includes: MasterKey authorizes the registered email and encrypted will, and the encrypted will and the target address of the digital asset are broadcast on the chain in a certain format through the registered email. The on-chain contract verifies the DKIM signature and encrypted will of the email. After the verification is passed, the on-chain contract authorizes the transfer of digital assets. The full name of DKIM in English is DomainKeys IdentifiedMail, and the Chinese translation is Domain Name Key Identified Mail Standard.

[0071] After being authorized by the digital wallet module, the identity storage module saves the original identity data submitted by the gig supply user off-chain and records the management authority settings of the gig supply user for different original identity data.

The full name of API is Application Program Interface, which is translated into Chinese as Application Program Interface.

[0079] The off-chain node unit collects data requested by the system from the off-chain and obtains the hash value of the response based on the hash algorithm.

[0080] The on-chain contract unit includes the node reputation contract, order matching contract and data aggregation contract deployed on the blockchain. Through smart contract technology, trusted data is submitted to the chain to process the system's data requests.

[0081] The digital signature unit uses cryptographic signature technology to sign the data sent from the off-chain node to the chain to prove that the data comes from a certain oracle node.

[0082] The blockchain module stores the hash value provided by the oracle module in a distributed peer-to-peer network.

[0083] The back-end unit of the task matching module provides a one-stop platform for the creation, design and operation of gig service projects for users with gig needs.

[0084] The front-end unit of the task matching module provides gig supply users with a one-stop collection of various gig demand projects, and matches the supply and demand sides of gig services.

[0085] Specifically, the task matching module provides the basic functions of decentralized business for accurate matching of supply and demand of gig services, including front-end units and back-end units.

[0086] The front-end unit provides a one-stop collection of various gig demand projects for gig service providers, and facilitates the management of the experience proof tokens obtained, including exploration function, space function, and credential set function. The exploration function displays various different gig demand projects at present and provides details. The space function displays all institutions or individuals that currently have gig demand and provides all their gig demand projects. The credential set provides the collection information of various experience proof tokens. The collection information only displays the total number of qualified users, related project links, and whether the user has a certain qualification, which is used for project recommendation and privacy protection.

[0087] The backend unit provides a one-stop platform for creating, designing and publishing projects related to gig services for the demanders of gig services, including space functions, credential management functions, experience proof contract deployment functions, and project publishing functions. The space function is used to create gig service demand projects, including detailed demand information.

The experience proof contract deployment function is used to issue corresponding experience proof tokens after users complete the gig service project. The input information includes but is not limited to the contract name, symbol, category, activation conditions, issuance rules, signatures, etc. The project publishing function provides various project marketing templates.

[0088] The privacy verification module verifies whether the characteristics of the gig supply user in the front-end unit of the task matching module meet the requirements of the gig demand in the back-end unit of the task matching module based on the gig supply user token on the blockchain module, while ensuring the privacy of the gig supply user.

[0089] The privacy verification module includes a label classifier and a verifier contract.

[0090] The tag classifier is used to create and manage off-chain information tags; information tags are two-dimensional arrays, including the information tag name index and retrieval timestamp of the proof class.

[0091] The validator contract is used to verify user requests on the chain, create and store verification results.

[0092] The information verification requirements submitted by the user to the validator include the set of information to be verified and the address for receiving the verification results; the information to be verified includes the information tag name, the user-declared value, and the remarks information.

[0093] The validator checks the on-chain information based on the zero-knowledge proof algorithm to confirm whether the proof submitted by the user is consistent with the information to be verified.

[0094] After passing the information verification, the validator will establish an information verification certificate on the chain and send the address containing detailed verification information to the receiving address, otherwise the restriction operation will be performed.

[0095] Specifically, the privacy verification module proves user characteristics by calculating user tokens and other on-chain information, while ensuring that user privacy is not leaked, including label classifiers and verifier contracts.

[0096] The tag classifier is used to create and manage off-chain information tags. The information tag is a two-dimensional array, including the information tag name index generatorIndex of the proof class and the call timestamp generatorTimestamp. The tag classifier supports combinable management methods, including but not limited to filtering, union, intersection and more complex operations, and each combination corresponds to a unique encoding groupID.

[0097] The validator contract is used to verify user requests, create and store verification results on the chain. The user submits information verification requirements to the validator, including the claim set of information to be verified and the destination address to receive the verification results. The information to be verified includes the information tag name groupID, the user's declared value claimedValue, and the remark information extraData. The user submits proof to the validator and sets privacy parameters. The privacy parameters determine the proportion of privacy, distribution, and scalability when performing privacy calculations. The validator checks the information on the chain based on the zero-knowledge proof algorithm to confirm whether the proof submitted by the user is consistent with the information to be verified. After passing the information verification, the validator will establish an information verification proof on the chain and send the Merkle root (a data structure) address containing detailed verification information to the receiving address, otherwise it will execute the throw() operation.

[0098] The issuance configuration unit of the reputation issuance module configures the issuance details and method of the experience proof token based on the request for experience proof token application from the gig supply user in the front-end unit of the task matching module, with the authorization of the gig demand user in the back-end unit of the task matching module.

[0099] The curation unit of the reputation issuance module randomly determines no less than three curator nodes based on the VRF function according to the request for experience proof token from the gig supply user in the front-end unit of the task matching module, verifies the issuance details and issuance method provided by the issuance configuration unit of the reputation issuance module, and after approval by all curator nodes, creates the issuance link of the experience proof token and sends it in the established manner.

[0100] The details of the issuance include the task unit link, the issuance object information, the issuance quantity, the token image and the template code. The issuance methods include the casting link, password text, website download and direct transmission. The casting link is the casting token of the authorization experience proof token, which is sent to the target object's mailbox in the form of a file in a specified format.

[0101] Specifically, the reputation issuance module is used by gig service demanders to issue experience certification tokens to service providers after the service is completed, including curation units and issuance configuration units.

[0103] The curation unit receives the request from the service provider to apply for the token, and randomly determines the curator node on the distributed network of the gig economy service platform based on the VRF function. The number of nodes is not less than 3, which is used to verify and approve the information submitted by the gig service demander in the issuance configuration unit. VRF is the full name of Verifiable Random Function in English, and its Chinese translation is Random Verifiable Function.

[0104] After all curator nodes approve the information submitted by the distribution unit, the curation unit creates a distribution link for the experience proof token and sends it in the established manner.

[0105] After the service provider receives and opens the minting link, he or she can enter the digital wallet address to activate the token communication module, create the corresponding experience proof token, and save it in the personal digital wallet.

[0106] After the gig supply user opens the issuance link provided by the curation unit of the reputation issuance module, the token communication module creates the corresponding experience proof token and saves it in the digital wallet module of the gig supply user.

[0107] Specifically, the token communication module integrates the communication protocol of user attribute proof and provides functions such as creation and retrieval, including passive acceptance and active management. The user's digital attribute proof is programmable, combinable, and non-transferable. The token collection it represents is the only reference for measuring the user's professionalism.

[0108] The experience proof token is a token that is bound to the identity proof NFT when it is created through the Mint function (casting function), and once created, it cannot be transferred. The experience proof token can call the NFT that owns the token through the owner function (holder function), call the detailed information about the token collection through the DataUri function (data collection function), and call the detailed information of the token creation instance through the EventUri function (event collection function). The full name of NFT in English is Non-Fungible Token, and the Chinese translation is non-fungible token.

[0109] The Mint function is used to create a proof-of-experience token. The variable parameters include the token code proofID, the NFT address nftAddress of the identity to which it belongs, and the NFT code nftID. The same proofID cannot be created twice.

[0110] The owner function is used to return the NFT information of the identity that owns the proofID, including nftAddress and nftID. If the proofID has not been created, the owner function uses throw() (restriction function) to restrict exception security. The owner function must always return the same result each time it is called after the proofID is generated. The return value of the owner function must always be the same as the variable parameter value corresponding to the proofID in the Mint function.

[0111] The DataUri function is used to retrieve detailed information about the experience proof token collection. The URI cannot be changed and points to content, including but not limited to ipfs: / / . The URI cannot point to changeable content, including but not limited to https: / / . The full name of URI in English is UniformResourceIdentifier, and the Chinese name is Uniform Resource Identifier. ipfs is a common distributed storage method, which is IPFS storage. https is a common information transmission method, which is web page transmission.

[0112] The EventUri function is used to call the details of the Proof of Experience token creation instance. The URI cannot be changed and points to content, including but not limited to ipfs: / / . The URI cannot point to changeable content, including but not limited to https: / / . The data called by the EventUri function has a higher priority than the DataUri function.

[0121] The privacy verification module verifies that the characteristics of gig supply users meet the specific requirements of gig demand by calculating the gig supply user tokens and other on-chain information, while ensuring that the privacy of gig supply users is not leaked.

[0122] After receiving the request from the gig supply user to apply for the experience proof token, the issuance configuration unit of the reputation issuance module configures the issuance details and issuance method of the experience proof token with the authorization of the gig demand user.

[0123] After receiving the request from the gig supply user to apply for the experience proof token, the curation unit of the reputation issuance module randomly determines no less than 3 curator nodes based on the VRF function, verifies the information submitted by the gig service demand user in the issuance configuration unit, and after approval by all curator nodes, creates the issuance link of the experience proof token and sends it in the established manner.

[0124] After the gig supply user opens the issuance link, the token communication module creates the corresponding experience proof token and saves it in the gig supply user's digital wallet.
