The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present application, it is noted that the terms "first", "second", "third", and the like are used merely for distinguishing between descriptions and are not intended to indicate or imply relative importance.

The content included in the account contract proposed in the embodiment of the present application and the related interactive functions that can be performed will be specifically explained below.

Fig. 1 is a schematic diagram of an account contract provided in an embodiment of the present application, please refer to fig. 1, where the account contract may include a plurality of accounts, specifically, may include a control account and a plurality of recovery accounts, and the account contract shown in fig. 1 is exemplified by having 3 recovery accounts, but is not limited thereto.

Optionally, fig. 1 includes an account a, an account B, an account C, and an account D, where the account a is a control account, the account B, the account C, and the account D is a recovery account, and each account may be controlled by one user through an electronic device, that is, the user a, the user B, the user C, and the user D in fig. 1.

The interactive functions that an account contract may perform include: forward transactions, change control accounts, loss-of-account, etc., account contracts may interact with application contracts on the blockchain.

Alternatively, the control account may be an account having control authority for the account contract, and the control account may perform work such as forwarding transactions, replacing control accounts, and the like through the account contract.

Alternatively, the recovery account may be an account having the account contract recovery authority, and the recovery account may perform work of replacing the control account, losing the account, or the like through the account contract. It should be noted that the user who is recovering the account may be a close friend of the user who controls the account.

Alternatively, forwarding the transaction may be the process of sending a transaction request to the application contract through the account contract, thereby effecting a forwarded transaction on the blockchain.

Alternatively, changing a control account may be the process of changing the current control account in the account contract to a new control account.

Optionally, the loss reporting account may be a control account of the account contract, where the account contract cannot initiate a forwarding transaction or the like for a certain time in a loss reporting state.

Optionally, the account contract may specifically be a contract set at a link point of the block chain, and is composed of the control account, the recovery account, and the above functions, and the account contract may perform information interaction with the application contract, thereby implementing interaction between nodes of the block chain.

Alternatively, the application contract may be a contract set on a node of the blockchain, and may perform information interaction with the account contract to forward a request, instruction, and the like sent by the account contract to other nodes on the blockchain. Wherein the application contract and the account contract may be located on the same node on the blockchain.

Optionally, the account on the blockchain may have a private key, a public key, and an address, where a public key (public key for short) and a private key (private key for short) are public keys of contents of an asymmetric encryption algorithm in cryptography, and the private key is to be safely kept. The private key is generated from a random seed, and the public key is derived from the private key through an algorithm. Since the public key is too long, for simplicity and practicality, the public key is characterized by an address, which is derived from the public key. These deductions are unidirectional and irreversible. That is, the address cannot deduce the public key, and the public key cannot deduce the private key.

Optionally, the current blockchain account address generation process is as follows: 256-bit private keys are generated through a cryptographic algorithm, public keys are deduced from the private keys, and addresses are deduced from the public keys, namely, the current account addresses can only be controlled by the private keys.

In the prior art, an account can only be controlled by a unique private key, cannot be modified and cannot be retrieved. When the private key is lost, the token or the managed information on the account cannot be obtained, the account is always out of control, and great inconvenience and economic loss are caused to the use of the user. And the private key is long in length, cannot be memorized by people, and can only be stored or recorded on paper through a terminal, for example, the private key is lost when the terminal is damaged or a recorded book is lost. The private key is difficult to store and cannot be retrieved, and the usability of the block chain is greatly influenced. In addition, when the private key is stolen, the private key cannot be reported.

Alternatively, each account may be an account obtained by registering application software in the electronic device, a user may perform operations related to the account through the electronic device, and different accounts may log in, operate on, and the like on different electronic devices, which is not limited herein.

The following explains a specific implementation procedure of the account contract based on the processing method of the account contract provided in the embodiment of the present application.

Fig. 2 is a first flowchart of a method for processing an account contract according to an embodiment of the present application, please refer to fig. 2, where the method includes:

s210: and sending a verification request to at least one second account in response to the command of replacing the control account initiated by the first account.

Wherein, changing the control account instruction comprises: to be replaced with the target account of the new control account.

Optionally, the first account is any account in an account contract, such as a control account or any one of the recovery accounts. The second account is any one of the recovery accounts.

Optionally, the control account replacement instruction is used to replace the current control account with a new control account, that is, a process for implementing the function of replacing the control account. The target account to be replaced with a new control account may be another account under the contract of the account, or may be any account specified by the initiating account instructed to replace the control account, which is not limited herein.

Optionally, the verification request may specifically be to inquire whether each second account agrees to perform control account replacement, the verification request may also include a target account to be replaced by a new control account, a current control account, a first account, and the like, and specifically, the content that may be carried may be set according to actual needs of the user.

Optionally, the instruction initiated by the first account to replace the control account may be specifically sent by the user through the first account on the corresponding application software through the electronic device, which is not limited herein.

For example: the user A can initiate a command of replacing the control account through the first account, and can send a verification request to the second account used by the user B according to the command of replacing the control account.

S220: and receiving the verification result sent by the second account.

Optionally, the verification result may be a recovery result corresponding to the verification request received by the user based on the second account, for example: the verification result may be a verification result that the user agrees with the replacement, or a verification result that the user does not agree with the replacement, and the specific verification result may be determined according to a related selection operation of the user on the second account, which is not limited herein.

Optionally, different second accounts may respectively send different verification results, and there is no correlation between the verification results.

S230: a new control account is determined based on the verification result.

Optionally, after receiving the verification result sent by each second account, a new control account may be determined according to the verification result. Specifically, the comprehensive determination may be performed according to the verification results sent by the plurality of second accounts, respectively.

For example: if both user B and user C send verification results through different second accounts, a new control account may be determined based on the two verification results in combination.

In the processing method of the account contract provided by the embodiment of the present application, a verification request may be sent to at least one second account in response to a control account replacement instruction initiated by a first account, where the control account replacement instruction includes: the method comprises the steps that a target account to be replaced by a new control account is obtained, the first account is any one of account contracts, and the second account is any one of recovery accounts; receiving a verification result sent by the second account; determining a new control account based on the verification result, wherein the method can be applied to a block chain node, and an account contract is deployed on the block chain node, and the account contract comprises the following steps: one control account and multiple recovery accounts. The method comprises the steps that a plurality of accounts are set in an account contract mode, when a private key of an account address of a control account is lost, other accounts initiate a process of replacing the control account, the whole account contract can be prevented from being lost, and therefore safety of the account contract can be improved.

Optionally, determining a new control account based on the verification result comprises:

and determining a new control account according to the information of the reference second account.

Optionally, the reference second account may be a second account that passes the verification after the sent verification result, and specifically, the determination of the new control account may be implemented according to whether the number of the reference second accounts meets a preset condition.

Alternatively, if the above condition is not satisfied, the current control account is kept unchanged.

Optionally, determining a new control account according to the information referring to the second account includes:

and if the reference second account exists, the target account is used as a new control account.

Alternatively, if the first account is a control account, the determination may be performed by using the method described above, and the control account may be actively replaced with a new control account.

Accordingly, if there is no reference second account, the current control account is kept unchanged.

Optionally, determining a new control account according to the information referring to the second account includes:

and if the number of the reference second accounts is larger than or equal to the preset number, taking the target account as a new control account.

Optionally, the manner of determining the new control account is different for different first accounts, and if the first account is a recovery account, the determination may be performed by using the method described above.

For example, if the number of the reference second accounts satisfies (X × 2/3-1) or more, the number of the reference second accounts may be considered to satisfy the preset condition, where X is the total number of the second accounts, and if the first account is the recovery account, the account defaults to that the verification result is verified, so that repeated calculation is not required.

Specifically, if restoring the account includes: account B, account C, and account D, where account B is the first account, and if the default verification of account B is passed, according to the preset calculation relationship, it satisfies (3 × 2/3-1), that is, if there is one second account in account C and account D as the reference second account, a new control account may be determined. And the determined new control account is the target account to be replaced by the new control account in the control account replacing instruction.

Optionally, the account contract further comprises: an account status identifier; the method further comprises the following steps:

and changing the account state identification of the block chain account contract into a frozen state in response to the loss report instruction sent by the recovery account.

Optionally, the account status identifier may be an identifier for characterizing the status of the account contract, and may include, for example, a normal status and a frozen status; the normal state may be a state in which the account contract can normally work; while the frozen state may be a state in which the account contract is prohibited from performing certain functions, such as: forbidding forward transactions, etc., and is not limited herein.

Alternatively, the loss report instruction may be an instruction indicating that the current control account has been lost, typically initiated by one of the recovery accounts.

Optionally, after receiving the loss report instruction, the account status identifier of the blockchain account contract may be changed to a frozen status, and the status is maintained for a preset time, for example: the time period is 10 hours, and can be specifically set according to actual requirements, and is not limited herein.

Optionally, when in the frozen state, the account contract may not execute the forward transaction process, but may still execute the function of replacing the control account, and when the preset time is exceeded, the frozen state may be automatically released, so that the account contract may be restored to the normal state.

Another specific implementation procedure of the processing method of the account contract provided in the embodiment of the present application is specifically explained below.

Fig. 3 is a second flowchart of a processing method of an account contract according to an embodiment of the present application, please refer to fig. 3, where the method further includes:

s310: a transaction request is sent to the application contract.

Wherein the transaction request includes an identification of the control account and an account status identification of the blockchain account contract.

Optionally, the application contract is another contract which can exchange information with the account contract, and the contract may also be configured on another node on the same blockchain, and the application contract may receive the transaction request sent by the account contract.

Optionally, the transaction request is a forward transaction function under the account contract, and processes such as performing transactions between an account under the account contract and other accounts can be realized through the transaction request, which is not limited herein.

Alternatively, the transaction request may be initiated by a control account in the account contract, and when the control account is lost, in order to prevent the control account from being maliciously utilized by a person to forward the transaction, the transaction request may be implemented by the aforementioned methods of losing the account, replacing the control account, and the like.

S320: a return instruction sent by the application contract is received.

Wherein the return instruction is used for indicating that the transaction request does not meet the preset condition.

Alternatively, the return instruction may be an instruction generated by the application contract according to the transaction request, and the instruction may be specifically used to indicate that the corresponding transaction request does not satisfy a preset condition, where the preset condition may be set by the user according to an actual situation, and is not limited herein.

Optionally, receiving a return instruction sent by the application contract, including: and if the identification of the control account is not matched with the control account of the current block chain account contract, receiving a return instruction sent by the application contract.

Optionally, the application contract may specifically be determined according to an identifier of the control account, where the identifier of the control account is used to characterize the control account of the account contract when the transaction request is initiated, and if the identifier is not matched with the control account of the current block chain account contract, it may be determined that the transaction request is not sent by the current control account, and a return instruction is correspondingly generated if the transaction request is not considered to be matched.

Optionally, receiving a return instruction sent by the application contract, including: and if the account status identifier of the block chain account contract is in the frozen state, receiving a return instruction sent by the application contract.

Optionally, in addition to the foregoing returning manner, the determination may be performed according to an account status identifier of the blockchain account contract, and if the status identifier is in a frozen state, it may be determined that the recovery account initiates a loss report operation, and accordingly, in the loss report operation state, the account contract may not execute the function of forwarding the transaction, and may generate and send a return instruction.

In the processing method of the account contract provided in the embodiment of the application, a transaction request can be sent to an application contract; a return instruction sent by the application contract is received. The account contract can be prohibited from performing the account forwarding transaction function through the return instruction, so that the account is prevented from being maliciously subjected to forwarding transaction under the condition of loss.
