[0049] In the embodiment, a management method of a blockchain smart account is provided, Figure 2 The flowchart of the management method of the blockchain smart account in the embodiment is shown in FIG. 2, which includes the following steps: Figure 2

[0050] In step S210, a management request of a user is acquired.

[0051] In step S220, when the management request is a creation request, initialization parameters in parameter information are set based on the creation request. The creation request includes a contract address, an owner address, and a parameter value.

[0052] In step S230, the parameter information is received and decoded in the blockchain to obtain a first decoding result. A corresponding smart contract is called according to the contract address in the first decoding result. Under the smart contract, a smart account of the user is created according to the owner address and the parameter value in the first decoding result.

[0053] ​It should be noted that the management request refers to a request initiated by a user, which can be a request related to the management of a smart account, including but not limited to a creation request, a use request, and an upgrade request, etc. Among them, the use request includes but is not limited to a transfer request, a recharge request, and a transaction request, etc. The specific form of the management request is not limited, for example: the management request can also include an account recovery request, a temporary key application request, etc.

[0054] For the management of a smart account in a blockchain, it can be divided into creation, use, and upgrade management modes. Among them, the creation of a smart account is the basis, and the use and upgrade are realized on the basis of the successful creation of a smart account.

[0055] The creation process of a smart account can be: obtaining a creation request of a user; based on the creation request, setting an initialization parameter in parameter information. Among them, the creation request includes a calling contract address, an owner address, and a parameter value. The initialization parameter (initCode) is determined by the calling contract address, the owner address, and the parameter value; for example: the format of the initialization parameter is in the format of Ethereum Application Binary Interface (ABI), the creation request is encoded in the format of Ethereum ABI to obtain the initialization parameter; the first 20 bytes of the initialization parameter are the calling contract address, and the subsequent owner address (which can also be 20 bytes) and parameter value. After completing the setting of the parameter information, the blockchain decodes the incoming parameter information according to the Ethereum bytecode to obtain a first decoding result; the first decoding result contains the calling contract address, the owner address, and the parameter value; then based on the calling contract address, the corresponding smart contract can be called; for example: the smart contract address is the address of the factory contract, the factory contract is called through the smart contract address, and the owner address and the parameter value are used to generate a smart account address, thereby completing the creation of a smart account of a user.

[0056] In the related art, the implementation scheme for the creation of a blockchain account is as follows: a solidity smart contract is written; in actual execution, the solidity smart contract is converted into bytecode, and the bytecode is executed through a virtual machine, thereby realizing the creation of an account. Since the virtual machine needs to be involved to read and execute the bytecode, the execution performance is low, the consumption is high, and it is difficult to apply on a large scale. In the present embodiment, a user's management request is obtained; when the management request is a creation request, an initialization parameter in parameter information is set based on the creation request; the creation request includes a contract address, an owner address, and a parameter value; the parameter information is received and decoded in the blockchain to obtain a first decoding result; a corresponding smart contract is called according to the contract address in the first decoding result; and a smart account of the user is created under the smart contract according to the owner address and the parameter value in the first decoding result, thereby solving the problem of low execution performance, high consumption, and difficulty in large-scale application in the related art. The creation of a smart account is completed by setting parameter information, without the intervention of a virtual machine, thereby improving the execution performance and reducing the consumption, and thus being applicable to large-scale application.

[0057] In some embodiments, under the smart contract, the smart account of the user is created according to the owner address and the parameter value in the first decoding result, including the following steps:

[0058] Step S231, under the smart contract, a smart account address of the smart account is generated according to the owner address and the parameter value, to complete the creation of the smart account of the user.

[0059] Step S232, the calling method parameter in the parameter information is set to be empty.

[0060] Specifically, the smart contract is only a program running on the Ethereum chain and cannot be manipulated by a person. It is a series of codes (functions) and data (states) located at a specific address on the Ethereum blockchain. Among them, the smart contract is an Ethereum account, which can be regarded as a smart contract account. It has a balance and can become the object of a transaction. A user can interact with the smart contract by submitting a management request to execute a certain function of the smart contract. The smart contract can define rules like a regular contract and automatically enforce them through code. By default, a smart contract cannot be deleted, and interaction with a smart contract is irreversible.

[0061] Therefore, based on the characteristics of the above smart contract, in the blockchain, a smart account address of the smart account can be directly generated according to the owner address and the parameter value, thereby completing the creation of the corresponding smart contract account of the user; and the intervention of a virtual machine is not required, thereby improving the execution performance and reducing the consumption. The parameter value can be a salt value, which is a random value generated by combining a user password. In other embodiments, the parameter value can be a random value obtained in other ways, which is not limited.

[0062] After the creation of the smart account of the user is completed, the smart account address remains unchanged after being generated to improve security. And the calling method parameter in the parameter information is empty, the calling method parameter is empty contract, the receive method and fallback method are implemented by default, thereby accepting the original points of the blockchain, and the corresponding parameter information is set for the newly created smart contract account through subsequent management requests to improve the execution efficiency of the use request or the upgrade request.

[0063] In some embodiments, the management method of the blockchain smart account includes the following steps:

[0064] After obtaining the first decoding result, it is judged whether the initialization parameter is empty or not.

[0065] If the initialization parameter is empty, the corresponding bytecode is read based on the calling contract address in the creation request through the virtual machine; and the smart account of the user is created based on the bytecode.

[0066] Specifically, in order to avoid the situation that the parameter information is not set successfully, affecting the creation of the smart account; when the initialization parameter is empty, the creation request is read through the virtual machine, the calling contract address is parsed from the creation request; the corresponding bytecode is read and executed based on the calling contract address; and the smart account address of the smart account is generated according to the owner address and the parameter value, so as to complete the creation of the smart account of the user.

[0067] Through the embodiment, when the initialization parameter is empty, the virtual machine is used to complete the creation of the smart account, and the stability of the operation is improved without the user's awareness.

[0068] Here, the complete scheme is implemented as follows:

[0069] Obtaining the management request of the user;

[0070] When the management request is a creation request, the initialization parameter in the parameter information is set based on the creation request; the creation request includes the calling contract address, the owner address and the parameter value;

[0071] The parameter information is received and decoded in the blockchain to obtain a first decoding result;

[0072] It is judged whether the initialization parameter is empty or not.

[0073] If the initialization parameter is empty, the corresponding bytecode is read based on the calling contract address in the creation request through the virtual machine; and the smart account of the user is created based on the bytecode.

[0074] If the initialization parameter is not empty, the corresponding smart contract is called according to the calling contract address in the first decoding result; under the smart contract, the smart account of the user is created according to the owner address and the parameter value in the first decoding result.

[0075] In some embodiments, the management method of the blockchain smart account further includes the following steps:

[0076] After the smart account of the user is created, the smart account address and the owner address of the smart account are stored in the blockchain; the smart account address remains unchanged.

[0077] Specifically, the smart account address is generated according to the owner address and the salt value, and after being generated, the smart account address is stored in the blockchain and remains unchanged. The owner address can be determined by the key of the user, for example: the owner address of the user is derived from the key of the user. If the key of the user is lost, the key is re-applied, and then a new owner address can be derived from the newly applied key. However, the smart account address will not change,

[0078] Through the embodiment, after the key of the user is lost, the user only needs to re-apply the key, and the use of the smart account will not be affected.

[0079] It should be noted that for management requests such as use requests and upgrade requests; after receiving such management requests of the user, the blockchain will execute these requests. Obviously, the blockchain can use the smart account to initiate a call to the smart account address. However, there may be malicious users who intentionally give some incorrect requests, thereby wasting the Gas fee. Therefore, signature authentication needs to be performed on these requests. In order to complete the above logic in a standardized manner, an "entry point" contract (EntryPoint) is introduced as an entry for the blockchain call. The EntryPoint will check whether the request of the user is legal, and then execute it as it is. That is, the management request sent to the blockchain can call the handleOps method of the EntryPoint system contract, and the contract is used as an entry contract of the smart account, and the use or upgrade of the smart account calls the contract.

[0080] The case where the management request is a use request is described below:

[0081] In some embodiments, as shown in Figure 3 The management method of the blockchain smart account further includes the following steps:

[0082] In step S310, when the management request is a use request, the calling method parameter and the signature parameter in the parameter information are set according to the use request and the key corresponding to the user;

[0083] Step S320, receiving and decoding the parameter information in the blockchain to obtain a second decoding result;

[0084] Step S330, signing and authenticating the use request according to the signature parameter in the second decoding result;

[0085] Step S340, after the signature authentication passes, calling the corresponding smart contract according to the calling method parameter in the second decoding result; under the smart contract, using the smart account of the user.

[0086] Specifically, the key can be pre-applied by the user, and the user applies through the terminal and stores it in the terminal. In addition to the initialization parameter, the parameter information also includes the calling method parameter (callData) and the signature parameter (signature).

[0087] The calling method parameter is used to use the smart account; it can be set based on the use request. For example: the creation request is a transfer request, which includes the recipient address and the transfer amount; the transfer request is encoded into the calling method parameter according to the format of Ethereum ABI; the first four bytes of the calling method parameter are the signature id of the function; the first four bytes of the calling method parameter are followed by the actual parameters of the calling function. The signature id of the function is obtained by calculating the function name and all input parameter types through an encryption algorithm. The function and the parameter type are related to the request; for the transfer request, the function is transfer; the parameter type is address type (recipient address) and uint256 type (transfer amount). Here, the function and the parameter type will not be illustrated one by one. The signature parameter is used to sign and authenticate the use request. The private key in the key is used to encrypt the owner address (which can be derived from the key when the request is made) to obtain the signature parameter.

[0088] The parameter information is received and decoded in the blockchain to obtain a second decoding result. The second decoding result includes the calling method parameter (recipient address and transfer amount) and the signature parameter; the signature parameter is decrypted using the public key in the key to obtain the owner address, and the decrypted owner address is verified with the owner address in the blockchain. If they are consistent, it is considered that the signature authentication passes, and the corresponding smart contract is called; under the smart contract, the smart account of the user is used according to the recipient address and the transfer amount.

[0089] It should be noted that when the smart account is used, if the smart account is not upgraded, all methods are predefined, and the corresponding smart contract can be directly called by the method. If the smart account is upgraded, the method involved may be user-defined bytecode. Before calling the corresponding smart contract, the predefined method is traversed based on the calling method parameters. If the predefined method is traversed, the ABI method is used to call the method, and the user's smart account is used according to the use request. If the predefined method is not traversed, the virtual machine is used to traverse. If it is traversed through the virtual machine, the user's smart account is used according to the use request; if it is not traversed through the virtual machine, an error is returned, and the use fails; thereby avoiding the situation that the user-defined bytecode affects the normal use of the upgraded smart account.

[0090] The encryption algorithm used by the EntryPoint system contract is consistent with the encryption algorithm used when setting the parameter information, which can improve compatibility; the encryption algorithm includes but is not limited to a hash algorithm, and no limitation is made thereto.

[0091] Through the embodiment, the security of the smart account use can be improved, and the execution performance and scalability of the blockchain can be balanced.

[0092] The case where the management request is an upgrade request will be described below:

[0093] In some embodiments, as shown in Figure 4 The management method of the blockchain smart account further includes the following steps:

[0094] Step S410, when the management request is an upgrade request, setting the calling method parameters and the signature parameters in the parameter information according to the upgrade request and the user's corresponding key;

[0095] Step S420, receiving and decoding the parameter information in the blockchain to obtain a third decoding result;

[0096] Step S430, signing and authenticating the upgrade request according to the signature parameters in the third decoding result;

[0097] Step S440, after the signature authentication passes, calling the corresponding smart contract according to the calling method parameters in the third decoding result; under the smart contract, upgrading the user's smart account.

[0098] In the embodiment, the calling method parameter is used for upgrading the smart account; and the calling method parameter can be set based on the upgrade request. For the upgrade request, the function is upgrade, and the parameter type is bytes. The signature parameter is used for signature authentication of the upgrade request. The owner address (which can be derived from the key at the time of the request) is encrypted by the private key in the key, and the encryption result is used as the signature parameter.

[0099] The parameter information is received and decoded in the blockchain, so as to obtain a third decoding result. The third decoding result includes the calling method parameter and the signature parameter. The signature parameter is decrypted by the public key in the key to obtain the owner address, and the decrypted owner address is verified with the owner address in the blockchain. If they are consistent, it is considered that the signature authentication is passed, and the corresponding smart contract is called. In the smart contract, the smart account of the user is upgraded according to the upgrade request.

[0100] Through the embodiment, the security of the smart account can be improved, and the execution performance and scalability of the blockchain can be balanced.

[0101] It should be noted that the management request is a composite request; the management request is a composite request; the composite request is at least two of the creation request, the use request and the upgrade request.

[0102] For example: the management request is the creation request and the use request (creation use request); the creation request and the upgrade request (creation upgrade request); the creation request, the use request and the upgrade request (creation use upgrade request); the use request and the upgrade request (use upgrade request), etc. In this way, the performance is guaranteed to be efficient, and the smart account is customizable for different management requests, supporting user-defined account functions.

[0103] The following will be described taking the management request of the creation use request as an example:

[0104] In some embodiments, as shown in Figure 5 The management method of the blockchain smart account further includes the following steps:

[0105] Step S510, when the management request is the creation use request, setting the initialization parameter, the calling method parameter and the signature parameter in the parameter information according to the creation use request and the key corresponding to the user; the creation use request includes the creation request and the use request;

[0106] Step S520, receiving and decoding the parameter information in the blockchain to obtain a fourth decoding result;

[0107] Step S530, creating the smart account of the user according to the initialization parameter in the fourth decoding result;

[0108] Step S540, signature authentication is performed on the use request according to the signature parameter in the fourth decoding result;

[0109] Step S550, after the signature authentication is passed, the corresponding smart contract is invoked according to the calling method parameter in the fourth decoding result; under the smart contract, the smart account of the user is used.

[0110] Specifically, the initialization parameter is set based on the creation request; the calling method parameter is set based on the use request; and the signature parameter is set based on the key; that is, for a composite management request, the parameter information is set at one time, thereby saving the execution time, and the specific setting process is not repeated here.

[0111] The parameter information is received and decoded in the blockchain, thereby obtaining the fourth decoding result. The fourth decoding result includes the initialization parameter, the calling method parameter, and the signature parameter.

[0112] The corresponding smart contract is invoked according to the calling contract address of the initialization parameter in the fourth decoding result; under the smart contract, the smart account of the user is created according to the owner address and the parameter value in the fourth decoding result, thereby completing the creation of the smart account. Then, the public key in the key is used to decrypt the signature parameter, thereby obtaining the owner address, and the decrypted owner address is verified with the owner address in the blockchain. If they are consistent, it is considered that the signature authentication is passed, and the corresponding smart contract is invoked; under the smart contract, the smart account of the user is upgraded according to the upgrade request.

[0113] The following takes the management request of the use upgrade request as an example for description:

[0114] In some embodiments, the management method of the blockchain smart account further includes the following steps:

[0115] When the management request is the use upgrade request, the calling method parameter and the signature parameter in the parameter information are set according to the use upgrade request and the key corresponding to the user; the creation request includes the use request and the upgrade request;

[0116] The parameter information is received and decoded in the blockchain, thereby obtaining the fifth decoding result;

[0117] Signature authentication is performed on the use upgrade request according to the signature parameter in the fifth decoding result;

[0118] After the signature authentication is passed, the corresponding smart contract is invoked according to the calling method parameter in the fifth decoding result; under the smart contract, the smart account of the user is used.

[0119] After the signature authentication is passed, the corresponding smart contract is invoked according to the calling method parameter in the fifth decoding result; under the smart contract, the smart account of the user is upgraded.

[0120] In other embodiments, similar principles can be employed to implement other forms of composite requests, which are not illustrated here.
