The following detailed description is provided with reference to the accompanying drawings. The following description of the embodiments is not intended to limit the preferred embodiments. Although a logical order is depicted in the flowchart, in some cases the steps shown or described may be performed in an order different than depicted in the figures.
In this embodiment, taking a terminal as an example for explanation, the present embodiment provides a DID contract management method applied to a blockchain, where an intelligent contract node is disposed in the blockchain, a target DID contract is set in the intelligent contract node, the target DID contract is configured to store a plurality of account addresses, account information is shared between account addresses in the target DID contract, the target DID contract includes a first account address of the account node, as shown in fig. 2, a specific flow of the DID contract management method may be as follows:
201. and sending a second account address to be added into the target DID contract to the account node through a target account node so as to trigger the account node to sign transaction contents to obtain target signature information containing the transaction contents and the signature, and sending the target signature information to the target account node, wherein the transaction contents comprise address introduction times of the first account address and the second account address, and the address introduction times are times that the first account address is a new address introduced into the target DID contract.
The target account node is a node where an account address of a target account to be added in the target DID contract is located, and the account address to be added in the target DID contract is the second account address.
It will be appreciated that, in the above-described characteristics of the target DID contract, after the second account address of the target account is added to the target DID contract, the second account address may share account information, such as asset information, of other address accounts in the target DID contract, so as to implement sharing rights held by the other address accounts.
Illustratively, the target DID contract may be an aggregate wallet address DID contract.
It will be appreciated that, since the second account address is not currently in the target DID contract, if the second account address is to be requested from the target DID contract, the second account address needs to be introduced into the target DID contract according to the account address that has been added to the target DID contract, that is, the first account address, which is in the account node, that is, in this embodiment, the target account may provide the attestation information for the target account according to the account node to which the first account address that has been added to the target DID contract belongs, so that the target account node holds the attestation information and requests address addition to the target DID contract.
In addition, in the process that the account node requests the target account to join the address in the target DID contract, if the target account node only sends the signature by using the private key to the account node to which the first account address belongs, the account node to which the first account address belongs initiates a transaction by using the private key of the first account address, so that the signature of the target account node and the related information of the signature are sent to the intelligent contract node, a great potential safety hazard exists, that is, a hacker can acquire the signature of the target account node by using the private key in a phishing manner, and based on the signature, the second account address of the target account node is added into the DID contract which can attack the user asset, that is, because account information can be shared between different account addresses in the target DID contract, the hacker can enjoy the rights of the account to which other account addresses in the target DID contract together with the target account by using the characteristics of the target DID contract, and thus the loss of the rights of the target account occurs.
In this embodiment, the second account address is sent to the account node through the target account node, so as to trigger the account node to sign the corresponding transaction content, thereby obtaining the target signature information including the signature content and the signature, where the target signature information is the certification information, and the account node sends the target signature information to the target account node to implement issuing of the certification information, so that the target account node holds the certification information to make a corresponding request, and security when the address joins the target DID contract is ensured.
In addition, the transaction content may include a current transaction event, a block height when signing the transaction content, an address introduction number of the first account address, the second account address, a transaction number or a time stamp, where the address introduction number is a number of times the first account address is a new address introduced by the target DID contract, and the transaction event is description information of the current transaction for indicating the current transaction; the transaction times are the total times of the transaction performed by the account node under the current transaction, and the time stamp is used for indicating the time of the current transaction.
Specifically, when the account node signs the transaction content, the account node may sign the transaction content based on a private key corresponding to a first account address corresponding to the account node.
In some embodiments, in order to improve security of the target DID contract, to avoid adding an inconsistent address to the target DID contract, identity verification may be performed on a target account node to which the second account address to be added in the target DID contract belongs, so as to ensure security of the target DID contract.
Specifically, before the account node signs the transaction content, the method may further include: and the account node performs identity verification on the target account node based on the second account address to obtain an identity verification result, wherein the identity verification result comprises that the identity verification passes and fails, then the identity verification result is judged, if the identity verification passes, the transaction content is signed, and if the identity verification fails, rejection information is sent to the target account node, and the rejection information can comprise the reason of the identity verification failure, so that the reminding of the target account node is realized.
Illustratively, the account node may perform identity verification on the target account node in a social manner.
202. And receiving the target signature information sent by the account node through the target account node, and sending the target signature information to the intelligent contract node.
In this embodiment, when the target account node receives the target signature information sent by the account node, it is described that the target account node obtains the certificate of the account node, and the target signature information is the certificate information provided by the account node, so that the target account node sends the target signature information to the intelligent contract node, so that the intelligent contract node performs corresponding processing based on the target DID contract deployed therein.
In some embodiments, the sending the target signature information to the smart contract node includes: and calling a DID contract function corresponding to the address introducing event through the target account node, and sending the target signature information to the intelligent contract node. The target account node may invoke the DID contract function corresponding to the address introduction event by using a private key corresponding to the second account address corresponding to the target account node, and send the target signature information obtained before to the intelligent contract node.
The address introducing event is the event of the current transaction, namely, the event of introducing the address of the second account into the target DID contract. It can be appreciated that different DID contract functions may correspond to different processing manners, so that the processing speed of the intelligent contract node may be increased by calling the DID contract function corresponding to the address import event.
203. And receiving the target signature information through the intelligent contract node, acquiring the address introduction times corresponding to the first account address in the target DID contract, and checking based on the address introduction times corresponding to the target signature information and the address introduction times in the target DID contract to obtain a checking result.
In this embodiment, after the smart contract node receives the target signature information, to ensure security, the smart contract node may obtain the number of address entries corresponding to the first account address in the target DID contract, so as to perform verification based on the number of address entries corresponding to the target signature information and the number of address entries in the target DID contract, to obtain a verification result, where the verification result includes a verification success result and a verification failure result, and when the verification result meets a preset verification result, the smart contract node may perform subsequent processing, for example, when the preset verification result is the verification success result, then when the verification result after verification is the verification success result, the smart contract node may perform subsequent processing.
In some embodiments, the verifying based on the address introduction times corresponding to the target signature information and the address introduction times in the target DID contract to obtain a verification result may include: when the address introduction times corresponding to the target signature information are consistent with the address introduction times in the target DID contract, determining that the verification result is successful; and when the address introduction times corresponding to the target signature information are inconsistent with the address introduction times in the target DID contract, determining that the verification result is a verification failure result.
204. And introducing the second account address for the target DID contract based on the verification result and the target signature information through the intelligent contract node.
In this embodiment, when the verification result meets a preset verification result, the smart contract node introduces the second account address to the target DID contract based on the target signature information.
The plurality of addresses in the target DID contract may exist in the form of an address list, and the introducing the second account address for the target DID contract may include: and adding the second account address into an address list of the target DID contract.
In some embodiments, in order to ensure security, in addition to the verification result obtained by performing verification based on the number of address importation, the smart contract node may further perform verification based on the target signature information, and may perform verification of other information, so as to importate the second account address for the target DID contract when the verification is passed.
In some embodiments, at least one verification manner may be designed for the above verification, so as to obtain a verification result corresponding to the at least one verification manner, where the verification result includes a verification success result and a verification failure result, so that when the verification result of the at least one verification manner meets a preset legal condition, a subsequent process is performed.
The preset legal conditions may be the successful verification results, that is, when the verification results corresponding to at least one verification mode are the successful verification results, the verification is passed; the preset legal conditions can also be the verification success results of a preset number, namely when the verification results of the preset number are verification success results in the verification results corresponding to at least one verification mode, the verification is passed, wherein the number of the verification modes is larger than or equal to the preset number; the preset legal conditions can also be the verification success results of the preset number with the highest priority, namely, the priority corresponding to each verification mode is set, so that when the verification results corresponding to the verification modes with the preset number with the highest priority are required to be the verification success results, the verification is passed.
