The issuing mode comprises casting link, password text, website downloading, direct transmission and the like. The cast link is a cast token that authorizes the passage of proof certificates, is uniquely non-reusable, is in the form of URLs, and is sent to the mailbox of the target object in the form of a txt file. Txt represents text format and URLs represent resource locators.
The curation unit receives a request of a service provider for claiming a pass, and randomly determines curator nodes on the zero-work economic service platform distributed network based on a VRF function, wherein the number of the nodes is not less than 3, and the curator nodes are used for checking and approving information submitted by a zero-work service requiring party in the issuing configuration unit. VRF english is known as Verifiable Random Function and chinese translation is a random verifiable function.
The curation unit creates a release link for the pass of the experience certificate after all curator nodes approve the release configuration unit to submit information, and sends the release link in a given mode.
After receiving and opening the cast link, the service provider inputs the digital wallet address, and then activates the pass communication module to create the corresponding experience evidence pass, and stores the pass in the personal digital wallet.
The pass communication module creates a corresponding experience proof pass after the zero worker supplies users to open the issuing link provided by the policy unit of the reputation issuing module, and stores the corresponding experience proof pass in the digital wallet module of the zero worker supplies users.

Experience attestation passing refers to passing that is bound to an identification NFT when created by a Mint function (casting function) and cannot be transferred once created. The proof of passage can call NFT with the pass through the owner function (holder function), call detailed information about the set of passes through the DataUri function (data collection function), and call detailed information about the instance of creation of the pass through the EventUri function (event collection function). The English version of NFT is called Non-Fungible Token, and the Chinese version is Non-homogeneous token.
The Mint function is used to create a proof of experience pass, and the variable parameters include pass code proofID, belonging identity NFT address NFTADDRESS, belonging NFT code nftID, the same proofID cannot be created twice.
The owner function is used to return the belonging identity NFT information, including NFTADDRESS, NFTID, of the proof of possession pass proofID. If proofID has not been created, the owner function limits the exception security in a throw () (restriction function) manner. The owner function must always return the same result at each call after proofID is generated. The return value of the owner function must always be the same as the variable parameter value corresponding to proofID in the Mint function.
The DataUri function is used to call the details of the experience attestation-passing set. URIs are not modifiable and point to content, including but not limited to ipfs:///. URIs cannot point to modifiable content, including but not limited to https://. The English language of URI is called UniformResourceIdentifier, and Chinese name is called uniform resource identifier. ipfs is a common distributed storage mode, and is IPFS storage. https is a common information transmission mode, and is web page transmission.
The EventUri function is used to invoke details of the experience attestation-to-creation instance. URIs are not modifiable and point to content, including but not limited to ipfs:///.
