[0033] Figure 1 FIG. 1 is a flow chart of a method for managing a distributed identity resolution system in an embodiment of the present disclosure. Figure 1 As shown, the management method of the distributed identity resolution system includes: S1: In response to receiving a target distributed identity resolution driver, storing the target distributed identity resolution driver through a distributed storage device, and providing the target distributed identity resolution driver to a set of voting nodes.

[0034] The provider of blockchain DID resolution driver can send an application request including the target distributed identity resolution driver to the smart contract of the blockchain system. After receiving the application request, the smart contract extracts the target distributed identity resolution driver from the application request, stores it in the distributed storage device, and can notify each voting node in the voting node set.

[0035] In the disclosed embodiment, the smart contract can automatically perform and execute the contract terms without the need for centralized management. The smart contract can be automatically executed, supervised and enforced to achieve automated control and supervision of transactions. Specifically, when the smart contract receives an application request from the target distributed identity resolution driver, the distributed identity resolution driver is automatically stored in the distributed storage device, and each voting node in the voting node set is notified.

[0036] The voting node set includes multiple voting nodes, and the multiple voting nodes can be nodes in the blockchain network, that is, some nodes can be selected from the blockchain as voting nodes, so as to review the newly added DID resolution driver by voting, so as to decide whether to allow the newly added DID resolution driver to be on the chain.

[0037] S2: The target distributed identity resolution driver is voted and reviewed through the voting node set to obtain the first voting result.

[0038] Each voting node in the voting node set can vote and review the target distributed identity resolution driver.

[0039] In some examples of the present disclosure, the voting review method is that each voting node casts an affirmative vote on the target distributed identity resolution driver to indicate its agreement to the target distributed identity resolution driver being on-chain. Each voting node has one vote. The smart contract can count the number of affirmative votes received during the voting period to obtain a first voting result. The first voting result includes at least the number of affirmative votes, and may also include the node information (such as node identification) of all voting nodes that voted in favor, and the node information of all voting nodes that did not vote.

[0040] In some other examples of the present disclosure, the voting review method is that each voting node can vote for, against, and abstain from voting on the target distributed identity resolution driver. Among them, each voting node has one vote, that is, each node can vote for, against, or abstain from voting (no vote by the expiration date is deemed to be an abstention). The smart contract can count the votes received from each voting node during the voting period to obtain the first voting result. If a voting node does not vote within the preset voting period, it is deemed that the voting node has abstained from voting. Among them, the first voting result includes at least the number of votes in favor, the number of votes against, and the number of abstentions, and can also include the node information of the voting nodes that voted in favor, against, abstain from voting, and voted.

[0041] S3: In response to the first voting result indicating that the target distributed identity resolution driver has passed the review of the voting node set, a target block including the target distributed identity resolution driver is generated, and the target block is chained on the blockchain.

[0042] According to the preset voting review pass condition, it is determined whether the target distributed identity resolution driver has passed the review of the voting node set according to the first voting result. Exemplarily, the voting review pass condition is that the ratio between the number of affirmative votes received during the voting period and the total number of voting nodes in the voting node set is greater than a preset ratio (e.g., 2 / 3), that is, during the voting period, a preset ratio (e.g., 2 / 3) of nodes agree to the target distributed identity resolution driver being put on the chain, then a target block including the target distributed identity resolution driver will be generated, and the target block will be put on the blockchain.

[0043] In this embodiment, due to the data tamper-resistant nature of the blockchain, and the fact that distributed storage technology can effectively reduce the risk of data being maliciously modified or deleted, the use of distributed storage technology and blockchain to store DID resolution drivers can reduce the risk of DID resolution drivers being maliciously modified, deleted, and lost, and the fairness of the review can be improved by voting on the distributed identity resolution driver.

[0044] In some embodiments of the present disclosure, after step S3, the following steps may also be included: S4: In response to receiving a download request from a user terminal for a target distributed identity resolution driver, providing the user terminal with download resources of the target distributed identity resolution driver, wherein the user terminal generates a download request after detecting the target block.

[0045] After the user terminal of the distributed identity resolution system logs in to the application of the distributed identity resolution system (hereinafter referred to as the identity resolution application), or after the user terminal of the blockchain logs in to the application provided by the blockchain system for DID resolution (hereinafter referred to as the blockchain application), when it is detected that the target block newly added to the blockchain carries the target DID resolution driver, a download request for the target DID resolution driver can be sent to the blockchain. The identity resolution application or blockchain application can provide the user terminal with the download resource of the target DID resolution driver so that the user terminal can download the target DID resolution driver, and then resolve the DID corresponding to the target DID resolution driver.

[0046] In this embodiment, when the user terminal detects that a target block with a target DID resolution driver is newly added to the blockchain, the target DID resolution driver can be downloaded through the target block so that the DID corresponding to the target DID resolution driver can be resolved.

[0047] Figure 2 is a partial flow chart of step S1 in some embodiments of the present disclosure. Figure 2 As shown, step S1 may include the following steps: S1-1: Obtain the index hash of the target distributed identity resolution driver on the distributed storage device.

[0048] Among them, the distributed storage device can generate an index hash for each storage information, thereby reducing the storage capacity.

[0049] After the target distributed identity resolution driver is stored in the distributed storage device, the distributed storage device generates an index hash of the target distributed identity resolution driver on the distributed storage device so that the storage address of the target distributed identity resolution driver on the distributed storage device can be quickly and accurately located through the index hash.

[0050] S1-2: Generate a voting request based on the index hash, and send the voting request to each voting node in the voting node set, so that each voting node obtains the target distributed identity resolution driver through the index hash.

[0051] The smart contract can generate a voting request including the index hash of the target distributed identity resolution driver on the distributed storage device, and send the voting request to each voting node in the voting node set.

[0052] After receiving the voting request, each voting node in the voting node set obtains the storage address of the target distributed identity resolution driver on the distributed storage device according to the index hash, and then can read the target distributed identity resolution driver from the storage address, and then can vote on the target distributed identity resolution driver to decide whether the target distributed identity resolution driver can be allowed to be on the blockchain.

[0053] In this embodiment, the distributed storage device can generate an index hash of the target distributed identity resolution driver by hash storage, thereby reducing storage capacity. A voting request for the target distributed identity resolution driver is generated according to the index hash, so that each voting node in the voting node set obtains the target distributed identity resolution driver through the index hash and votes.

[0054] In some embodiments of the present disclosure, after step S2, the following steps may also be included: storing the first voting result in the blockchain.

[0055] The smart contract can generate a block including the first voting result based on the first voting result, and chain the block on the blockchain so that blockchain users or users of the identity resolution system can obtain the first voting result through the blockchain.

[0056] In this embodiment, by storing the first voting result corresponding to the target distributed identity resolution driver in the blockchain, the blockchain user or the user of the identity resolution system can understand the first voting result, realize the public review result of the distributed identity resolution driver, and help promote the open and fair review of the distributed identity resolution driver.

[0057] In some embodiments of the present disclosure, before step S1, the following steps may also be included: S0: Generate a set of voting nodes through voting consensus.

[0058] Figure 3 FIG. 1 is a flow chart of step S0 in some embodiments of the present disclosure. Figure 3 As shown, step S0 may include the following steps: S0-1: Get the specified block from the blockchain.

[0059] The designated block includes node information of multiple candidate voting nodes, such as node identification and credit information of multiple candidate voting nodes. The credit information of each candidate voting node can identify the credibility of the behavior of the corresponding candidate node on the blockchain (such as generating a valid block).

[0060] The specified block can be generated on the blockchain through a smart contract.

[0061] S0-2: Voting on the designated block through multiple candidate voting nodes to obtain the second voting result.

[0062] The designated block can be voted on by multiple candidate nodes in the designated block, that is, whether multiple candidate nodes in the designated block can generate voting nodes can be voted on to obtain a second voting result. The second voting result at least includes: which candidate nodes among the multiple candidate nodes are agreed to become voting nodes.

[0063] S0-3: In response to the second voting result indicating that the plurality of candidate voting nodes reach a consensus on the designated block, a voting node set is generated based on the plurality of candidate voting nodes.

[0064] According to the preset consensus protocol, it is determined whether the multiple candidate voting nodes have reached a consensus on the specified block according to the second voting result. If it is determined that the multiple candidate voting nodes have reached a consensus on the specified block, it is possible to obtain which candidate nodes of the multiple candidate voting nodes become voting nodes according to the consensus information, and all the voting nodes form a voting node set.

[0065] In this embodiment, the voting method determines the voting nodes in the voting node set from the candidate voting nodes, which helps to improve the fairness of the voting node set in the audit of the distributed identity resolution driver.

[0066] Figure 4 FIG. 1 is a partial flow chart of a method for managing a distributed identity resolution system in some embodiments of the present disclosure. Figure 4 As shown, the management method of the distributed identity resolution system may further include the following steps: S5: In response to receiving a node joining request for the voting node set, voting is performed on the target node through the voting node set to obtain a third voting result.

[0067] When a target node wants to join the voting node set, it can send a node joining request to each voting node in the voting node set through a smart contract. The node joining request includes the target node that requests to join the voting node set, and the target node may include a new node in the blockchain that wants to join the voting node set.

[0068] The smart contract can initiate a vote to each voting node in the voting node set on whether to allow the target node to join the voting node set, and obtain the voting results of each voting node in the voting node set for the vote, that is, the third voting result.

[0069] S6: In response to the third voting result indicating approval for the target node to join the voting node set, the target node is added to the voting node set.

[0070] If the third voting result indicates that the target node is approved to join the voting node set, for example, more than a preset proportion (eg, 2 / 3) of the voting nodes vote in favor, the target node is added to the voting node set.

[0071] In this embodiment, through voting consensus, it can be fairly determined whether the target node can join the voting node set, which helps to improve the voting node set's fair review of the DID resolution driver.

[0072] Figure 5 FIG. 1 is a working principle diagram of a management method of a distributed identity resolution system in an example of the present disclosure. Figure 5 As shown, the DID resolution driver provider sends an application request including a target distributed identity resolution driver to the smart contract through the contract interface provided by the smart contract of the blockchain. After receiving the application request, the smart contract stores the target distributed identity resolution driver in the distributed storage device through the distributed storage device interface, and can obtain the hash index of the target distributed identity resolution driver in the distributed storage device. The smart contract sends a voting request carrying the hash index to each voting node in the voting node set through the voting interface. Each voting node in the voting node set can obtain the target distributed identity resolution driver from the distributed storage system according to the hash index and vote to obtain the first voting result. If the first voting result indicates that the target distributed identity resolution driver passes the voting review of the voting node set, the target distributed identity resolution driver is chained on the blockchain. Afterwards, when the user terminal detects that the target distributed identity resolution driver is chained on the blockchain, it downloads the target distributed identity resolution driver from the block storing the target distributed identity resolution driver so as to resolve the DID corresponding to the target DID resolution driver.
