Detailed Description

The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.

As shown in fig. 1, this embodiment provides a block chain-based transfer method, including:

step S110: receiving a transfer request broadcast by a transfer party, wherein the transfer request carries a transfer party identifier of the transfer party;

step S120: inquiring a transfer address based on the transfer-in party identification;

step S130: responding to the transfer request based on the transfer address.

The blockchain transfer method provided by the embodiment is applied to a blockchain network, for example, a network for blockchain transfer such as a blockchain wallet. The blockchain network comprises: a plurality of distributively arranged blockchain nodes. The block chain link points can be divided into the following parts according to functions: account book node and supervision node. The book node may be configured to record information and generate blocks in a block chain. The policing node may be used to perform information verification on information in the blockchain and/or the blocks themselves, etc. It should be noted that the block chain based transfer method provided in this embodiment may be applied to the block chain network shown in fig. 9, but is not limited to the block chain network, and may also be applied to a public block chain network generated by a public chain that simultaneously undertakes execution of service logic, verification of execution results, and the like, for example, in the same block chain node, or a private block chain network generated by a private chain.

In this embodiment, the transfer-out party of the transfer may broadcast the transfer request in the blockchain network, so that a plurality of blockchain nodes in the blockchain network can receive the transfer request in a broadcast manner.

The transfer-in party identifier carried in the transfer request is not a direct transfer address; the transfer-in party identifier may be various information uniquely identifying the transfer-in party in the block chain, for example, code information uniquely identifying the transfer-in party, information uniquely identifying the real identity of the transfer-in party, and the like. For example, the transferring-in party is identified by an email address of the transferring-in party, and the transferring-in party is identified by a timely communication account such as a social account (e.g., a micro-signal, a micro-blog number) of the transferring-in party. In some embodiments, the transfer address may include: the account address that the user registered when registering in the blockchain network.

Because the transfer request initiated by the roll-out party is not directly carried with the transfer address generated in the blockchain transfer, on one hand, the roll-out party can initiate the transfer even if the roll-in party does not receive the transfer address; on the other hand, because the transfer party does not need to obtain the transfer address, the user of the transfer party does not need to memorize the transfer address or write the transfer address which is boring and unfavorable for memorizing in the transfer page, thereby avoiding the transfer error caused by the problems of input or misoperation and the like in the transfer address; on the other hand, a user of one transferring party may transfer to a plurality of users of transferring parties at the same time or at different times, and although the transfer addresses are different for the blockchain network, the users have similarity of composition structures and the like, which easily cause the users to select errors and the like to cause wrong transfers, and the errors may include: transfer amount is wrong, and transfer is carried to the wrong transfer-in party. Therefore, the transfer request is sent and received by using the transfer-in party identification of the transfer-in party in the embodiment, the requirements on the user can be greatly reduced, the convenience of the user is improved, and the transfer efficiency is improved.

In some embodiments, the transfer-in party identifier may be a communication identifier of the transfer-in party; the communication identification may include: a mobile communication identity (e.g., a mobile phone number, or a device identity of a user equipment such as a mobile phone, an email address, or a social account number). The device identification may include: international Mobile Equipment Identity (IMEI), etc. Of course, the transferring party identifier is not limited to the communication identifier, and may also be unique identification information such as a code number of the transferring party, which may not be a serial number or a character string used by the transferring party in other applications with communication functions.

For example, a user a wants to transfer money to a user B, and at this time, the user a may initiate a transfer request based on an address book stored in a mobile phone (the address book may include an address book of a mobile phone number, an address book of a social account number of a social application, and an email address such as an email address), and the like, of the user B, the user a of the roll-out party may store the mobile phone number of the user B in the address book, or initiate the transfer request based on a micro signal, and the transfer request does not carry a transfer address of a block chain applied by the user B in the block chain, and thus, on one hand, the user a must send the transfer address to a device of the user a through a block chain network or a device of the user B, and does not need to initiate the transfer request after generating an unequal transfer address; on the other hand, the user A avoids the problems of operation errors and the like in the transfer process, thereby simplifying the transfer process and reducing the error rate of transfer.

After receiving the transfer request in step S120, the transfer address may be queried with the transfer destination identifier based on the transfer destination identifier carried in the transfer request.

In step S130, the block chain transfer is performed by the block chain link point based on the transfer address, and the security of the transfer is ensured by using the security and traceability of the block chain transfer, and the like.

In some embodiments, the step S120 may include:

the step S130 may include:

When a transfer request is received, a transfer address may not be generated in the blockchain network, at this time, it may be required to confirm whether the transfer address is generated, if the transfer address is generated, the currently generated transfer address may be used for performing blockchain transfer, and if the transfer address is not generated, subsequent operations may be performed according to a predetermined blockchain transfer logic. For example, in some embodiments, the method further comprises: if the transfer-in party identification does not correspond to the transfer address to be transferred; and generating the transfer address corresponding to the transfer-in party identifier.

And if a transfer request generated by a transfer party is received and a corresponding transfer address is not generated currently, executing the business logic of the block chain transfer address to generate the transfer address. And then block chain transfer is carried out based on the generated transfer address. Here, after the transfer address is generated, the transfer address needs to be broadcast, so that the transfer address is verified by the supervision node to pass through and is recorded by other account book nodes, and subsequent successful transfer and generation of corresponding transfer records in the transfer block chain are facilitated.

Of course, in some embodiments, the generation of the transfer address may include the following process:

after receiving the transfer request, a transfer address is not generated, and a transfer reminder is sent to a transfer-in party, wherein the reminder can carry a transfer-in party identifier;

and after receiving an agreement response of the transfer-in party on the transfer reminding, generating a block chain transfer address.

In other embodiments, because the transfer relates to fund and/or asset security, the transfer party does not initiate a transfer request at will, and generally, the user of the transfer party and the user of the transfer party have negotiation, and both parties know the conditions, and under such a condition, the generation flow of the transfer address can be directly started under the condition that the transfer request is received and the transfer address is not generated, so as to ensure the smooth transfer and reduce the time delay of the transfer, and avoid the problem of large transfer delay caused by the fact that the user of the transfer party does not use an electronic device or is not connected to a network currently.

In some embodiments, the transfer request may carry the transfer party identifier in addition to the transfer party identifier, so as to facilitate generation of a block in a transfer block chain in a subsequent transfer process.

In some embodiments, the transfer target corresponding to the transfer request in this embodiment may be a fund or an asset other than the fund. The assets herein can be various electronic assets, and the electronic assets herein can be assets that are circulated and/or applied in an electronic device and/or network. For example, the electronic assets may include: the game props and game coins of the network game can further comprise: account assets of a certain type of application, for example, a music account number for which copyright tax needs to be paid is purchased, download rights of a certain music, viewing rights of a movie, and the like. For another example, the electronic asset may further include: an asset card for a shopping application, such as a shopping card or point redemption card for an e-commerce platform, etc. The electronic asset may further comprise: equity and/or debt, etc.

In summary, the transfer is not limited to the transfer of funds in the present embodiment, and may be an electronic asset other than funds. The funds are related to currencies, e.g., RMB, USD, Japanese dollars, Hongkong dollars, etc.

In some embodiments, the transfer request may also directly carry the amount of the transfer target, where the transfer target may be the aforementioned funds and/or electronic assets. Payment accounts for transfers, etc. For example, the payment account may be a transfer-in address used in a blockchain of the transfer-in party, or a bank card account, or a payment account of a payment platform such as a payment bank or a WeChat, so that a transfer target of a corresponding amount may be paid based on the payment account in the transfer process.

If the transfer request also carries the amount of the transfer target and the payment account of the payment transfer target, after the block chain link receives the transfer request, the block chain transfer can be completed under the condition that information interaction is not performed between the block chain link and the equipment of the transfer-in party or between the block chain link and the equipment of the transfer-in party as little as possible after the block chain link inquires the transfer address, and the transfer efficiency is improved under the condition that the block chain transfer is utilized to ensure the safety of transfer transaction and the like.

In this embodiment, the correspondingly storing the transfer-in party identifier and the transfer address may include:

the transfer-in party identifier and the transfer address are correspondingly stored in the same record, so that the transfer-in party identifier and the transfer address can be known at the same time by inquiring the record; and/or the transfer-in party identification is stored in a first record;

the storage address is stored in a second record, and the first record stores therein related information that can access the second record, for example, an access address, access authentication information, index information, and the like of the second record.

Thus, querying the transfer address may include:

inquiring the first record based on the transfer-in identifier to obtain the related information of the second record;

querying the second record based on the relevant information.

To ensure the security of the information, the first record and the second record may be stored separately, e.g., in different nodes or in different domains.

In other embodiments, in order to ensure the security, authentication is required when the transfer-in party identification and the transfer address are accessed, and after the authentication is passed, the corresponding record is ensured to be accessed, so that the access security is ensured.

For example, as shown in fig. 2, the step S120 may include:

step S121: sending a query request carrying the transfer-in party identifier to a predetermined database;

step S122: receiving a query response returned based on the query request;

step S123: determining the transfer address based on the query response.

In this embodiment, the transfer-in party identifier and the transfer address, or the corresponding relationship between the transfer-in party identifier and the related information of the transfer address. In this embodiment, the blockchain node sends a query request to a predetermined database, and obtains a query response based on the query request.

In some embodiments, the predetermined database may be a distributed database or a centralized database.

In some embodiments, querying the transfer address may further comprise: and inquiring the transfer address from the block chain by taking the transfer-in party identifier as an inquiry basis according to the block chain.

In some embodiments, the step S120 may further include:

step S124: acquiring a contract address carried in the query response;

step S125: access contract information based on the contract address and read the transfer address in the contract information.

The contract address may be an address capable of accessing contract information, and the contract address may point to an address of a certain block in a block chain network or a memory space in the book node.

In summary, the contract address points to the contract information, and through the contract address, the block link point (transfer node) participating in the main installation can inquire the contract information and extract the transfer address from the contract information.

For example, the contract information has defined therein contract content that may be required as information content recorded into the blockchain. Of course, in this embodiment, the contract information at least includes a transfer address, which is convenient for the transfer node to extract the transfer address corresponding to the transfer destination identifier from the contract information.

The contract content may include:

the real-name information of the transfer-in party user can be applied to identify the identity information of the transfer-in party user, so that transparent transfer of transparent transfer requirements can be conveniently met, and illegal transfer of black money or black assets and the like by using block chain transfer and tracking of illegal transfer are reduced.

The contract content is not limited to the real-name information of the transfer-in party user.

In some embodiments, the contract information further includes contract codes, and the contract codes are executed to implement corresponding business logic and provide corresponding services.

For example, the contract code may include constraints that define the use of the identity information, and if executed, may define whether the constraints for reading or using the real-name information are currently satisfied, and if so, the real-name information may be allowed to be read and/or invoked.

For another example, the contract code may define contract functions, and the corresponding information may be read through the invocation of the contract functions, for example, the contract information may be configured with a specific storage space for storing the transfer address. And if the query function is called, the transfer address can be quickly read.

In other embodiments, the contract function may further include an update function for the transfer address, and the update function may include: writing the generated transfer address into a specific space of the contract information for the first time, and replacing the old transfer address with the newly generated transfer address or replacing the transfer address which is invalid.

Optionally, the method further comprises:

For example, the transfer address is signed by using the transfer-in party identifier to form signature information, and for example, the transfer address is calculated by using an asymmetric encryption algorithm to obtain signed signature information.

Therefore, after the supervision node receives the transfer information, the transfer address stored by the supervision node can be combined with the transfer party identifier for signature, if the signature information obtained by signature is consistent with the signature information in the broadcasted transfer information, the current transfer can be considered to be correct, and the supervision node can throw a ticket passing verification; and finally writing the verified transfer information into the transfer blocks in the transfer block chain based on the vote counting of the voting mechanism and the like.

In the embodiment, the supervision node utilizes the transfer-in party identifier to sign and verify the transfer address known by the supervision node, so that the corresponding relation between the transfer-in party identifier and the transfer address is determined again, and the error occurrence of transfer can be reduced.

As shown in fig. 3, the present embodiment provides a block chain-based transfer method, including:

step S210: detecting transfer operation;

step S220: and based on the transfer operation, broadcasting a transfer request carrying a transfer-in party identifier to the blockchain network, wherein the transfer-in party identifier is used for determining a transfer-in address of a transfer-in party receiving the transfer.

In some embodiments, the step S210 may include: the transfer instruction of the transfer party user is received by utilizing an interactive interface such as a human-computer interactive interface (e.g. a keyboard, a touch screen, voice detection and eye gestures).

In other embodiments, the step S210 may further include: the transfer operation is received from another device, for example, a remote control device. In other embodiments, the transfer operation may further include a built-in operation preset in a client (e.g., an Application (APP), Software Development Kit (SDK), or plug-in) of the transferring party or an electronic device held by the transferring party, such as purchasing an asset in advance, and when the asset is transacted, a payment transfer is required. In this case, the transfer operation may also be preset in the client or the electronic device, and thus, the transfer operation may also be a transfer operation built in the device.

And after the transfer operation is detected, a transfer request is broadcast to the block chain network, and the block chain transfer process is triggered to be realized. It should be noted that in the embodiment of the present invention, the transfer request carries the identifier of the transfer-in party instead of the transfer address. Therefore, the transfer address does not need to be generated in advance, the transfer party user does not need to manually input or copy and paste the transfer address which is irregular and tedious and difficult for the user to have memory and distinguish, the user operation is simplified, and the transfer error rate is reduced.

As shown in fig. 4, the step S220 may include:

step S221: displaying an address book according to the transfer operation;

step S222: detecting a selection operation acting on the address book;

step S223: and broadcasting the transfer request to the block chain network according to the transfer-in party identifier executed by the selection operation.

The address book can be a sequence list of various communication identifiers, such as a mobile phone number address book, a social account number address book, and an address book of an electronic mailbox address. The address book usually has the name, nickname and the like of the transfer party, which is convenient for the user of the transfer party to identify. The name and nickname are much more memorable and recognizable to the user than the transfer address formed by one or more of character strings (numbers, letters and symbols, which may be up to 20 bytes), thus facilitating the user to send a transfer request by selecting a referrer identifier through the contents in the address book.

In some embodiments, the transfer party identifier may also transfer a party code number, and the transfer party code number may have a unique correspondence with the transfer party identifier in the address book. For example, the name and the phone number of the friend user B of the user a recorded in the address book, in order to reduce the exposure of the phone number of the user B in the network, the method further includes:

and selecting the code number of the user B according to the corresponding relation between the mobile phone number of the user B and the code number of the user B, adding the code number of the user B into the transfer request, and broadcasting the transfer request to the block chain network.

The address book may have a plurality of communication identifiers, and in this embodiment, a selection operation may be detected, and the selection operation may be various types of user operations such as a click operation and a slide operation, so that a user can select a transfer party identifier from the address book according to a current demand to transfer money.

For example, a transfer operation is detected on an application interface of a transfer application, and after the transfer operation is detected by the transfer application, an address book is automatically called through an interface with the address book, and the address book is displayed; for example, the user can cut into the address book application and display an application interface of the address book application, and various communication identifiers are displayed in the application interface. After the address book application is called, the operating system records a calling event, and after the corresponding transfer party identifier is selected, the operating system can control or trigger the exit of an application interface of the address book by the transfer application based on the calling event, return the application interface of the transfer application, and continue the subsequent transfer related operation, for example, return a generation page of a transfer request, and prompt a transfer user to input one or more of information such as a transfer amount, a transfer target and a transfer message.

In the embodiment of the invention, when the block chain transfer is initiated, the block chain transfer is automatically switched to the corresponding address book, for example, if the transfer application can call the address book through interfaces between the transfer application and various address books, for example, the transfer application can call a mobile phone number communication, a social account address book or a mailbox address book of an email application under the authorization of a user, so that the interfaces between the corresponding applications are opened.

As shown in fig. 5, the present embodiment provides a blockchain transfer apparatus, including:

the receiving module 110 is configured to receive a transfer request broadcasted by an transferring party, where the transfer request carries a transferring party identifier of a transferring party;

a query module 120 for querying a transfer address based on the transferor identifier;

and a transfer module 130 for responding to the transfer request based on the transfer address.

The receiving module 110, the query module 120 and the transfer module 130 are program modules, and after being executed by the processor, the broadcast of the transfer request can be realized, and the broadcast includes: and the broadcast message takes the broadcast address as a destination address, and the content carried by the broadcast message at least comprises the transfer request.

The query module 120 queries the transfer address corresponding to the transfer request with the transfer-in party identifier as a query basis. The transfer address may be generated for the corresponding user for the blockchain network.

After inquiring the transfer address, the transfer can be completed based on the transfer address in response to the transfer request, and a transfer message is generated and can be recorded in a block chain form as a transfer record by the account node after being written into the transfer block.

In some embodiments, the query module 120 is specifically configured to query whether the transfer-in party identifier corresponds to a transfer address to be transferred;

the transfer module 130 is specifically configured to respond to the transfer request based on the transfer address if the transfer destination identifier corresponds to the transfer address to be transferred.

In another embodiment, if not, the method further comprises: if the transfer-in party identification does not correspond to the transfer address to be transferred; and generating the transfer address corresponding to the transfer-in party identifier. Thus, when a transfer request is received and a transfer address to be paid is not generated, the transfer address may be generated first. In this embodiment, the query module 120 also generates the transfer address, which may be generated based on the related art. For example, a first pre-determined algorithm is used to process a blockchain wallet (a type of blockchain account) of the transferring party to obtain a first calculated value; and processing the first calculated value based on a second preset algorithm to obtain a second calculated value, wherein the second calculated value or part of the second calculated value can be used as the transfer address. The first calculation algorithm and the second calculation algorithm are different. At least one of the first algorithm and the second algorithm has a certain randomness. Or after the two algorithms process the blockchain wallets of the transferring party in sequence, certain randomness is generated, so that the generated transfer addresses have difference. In some embodiments, the first algorithm may be an elliptic curve cryptography algorithm and the second algorithm may be a hash algorithm. In a specific implementation, the first algorithm and the second algorithm are not limited to the elliptic curve cryptography algorithm and the hash algorithm.

Optionally, the apparatus further comprises:

Several specific examples are provided below in connection with any of the embodiments described above:

example 1:

in the registration link, a data record of the digital asset transaction real-name information intelligent contract block is created. The data record stores the real name information of the user.

The real name information may include at least one of: real name, valid certificate information, gender, authentication mailbox, registered mobile phone number, generated block transfer address and the like. The real name may be identification information recognized by an official, for example, a name registered in a house, a name written on an identification card or a passport, or the like.

The real name information to be stored is stored by the accounting node after being voted and confirmed to pass the verification by the supervision node (the supervision node can be one of the block chain nodes, and in some cases, the supervision node can be one of the supervision nodes) in the alliance chain (block chain network) in a block broadcasting mode.

The real-name information is defined in the intelligent contract to be stored in a form of using key value pairs, a main key uses identification information (e-mail address, social account number and the like), and the value is a data entity of the real-name information.

Real name information in the intelligent contract is stored on each block chain node of the block chain, and the real name information and the transfer address of a user of the intelligent contract are pointed to by the contract address.

The specific transfer steps may include:

initiating a transfer request and addressing a transfer address based on a transferor identifier in the transfer request

In the transaction, after the transfer party selects the transfer party, a transfer request can be initiated (the email address of the other party is directly filled in, or if the email address is unwilling to be directly displayed in the transaction, the email address and the code number information are mapped to form a mapping relation), and the code number information which has the mapping relation with the email address is carried in the transfer request at the moment.

The generation of the transfer addresses can be generated one by one, for example, a transfer address is generated at present, if the transfer address does not receive the transfer, the transfer address is kept effective all the time or kept effective within a specified time, and the generation of other transfer addresses is shielded, so that one transfer-in party only corresponds to one effective transfer address. The effect here may be: an address for the transfer may be received. Therefore, if the user already has a block transfer address, a new address is not created. And inquiring the real name information of the target user and the transfer address carried by the real name information through a function of the real name information intelligent contract.

Generating a block transfer address may include:

according to the private key of the block wallet of the target user, a public key corresponding to the private key is calculated by using an elliptic curve encryption algorithm (ECDSA-secp256k 1).

Calculating a hash value of the public key, e.g., calculating a Keccak-256 hash value of the public key;

and taking the last 20 bytes of the calculated hash value.

Digital signature of transfer address, comprising:

the transfer address is signed using a symmetric encryption Algorithm (AES), the encryption result is encoded using base64, and the key is the user's email. While the initiator account address is signed using the same principles.

The digital signature is sent together with other transaction information by block packaging. Block packing herein may include: the digital signature and transaction information (corresponding to previous transfer information) is written into the blocks of the blockchain.

Verification prior to block packing may include:

and verifying the transfer addresses of both transfer parties, and encrypting the transfer addresses by using the electronic mailbox of the target user (the transfer party).

And if the encrypted ciphertext is consistent with the signature ciphertext, the verification is passed. Otherwise, the transaction fails and the transfer transaction rolls back.

Transfer result confirmation may include:

in order to improve performance, a partial centralization mode can be adopted in a alliance chain, and all parties designate supervision nodes. For example, both sides of the transfer account are verified, and the transfer account address is encrypted by using an electronic mailbox of a target user as a key; and/or, if the encrypted ciphertext is consistent with the signature ciphertext, the verification is passed. Otherwise, the transaction fails and the transfer transaction rolls back.

With the automatic account transfer addressing scheme of the example, the transfer party does not need to memorize complex block addresses any more during the transaction of the digital assets, and does not need to worry about address filling errors. For the transfer party, a transfer address does not need to be generated for each transfer party user, the problem of address error does not need to be worried about, the transaction speed is improved, and the transaction accuracy is guaranteed.

The key point of the automatic addressing of the transfer accounts is that the real-name information is stored by using a block chain, so that the real-name information is not tampered; the real-name information is used for carrying out digital signature in the block transfer process, so that the transfer address is guaranteed to be real and effective; and checking the digital signature in the block packaging and transaction confirmation links to check the authenticity of the transaction.

This example is based on all of the above problems and proposes a solution for automatic addressing of block transfers. The method solves the problems that various errors are easy to occur and disputes are generated in the process of transferring the complex block addresses among users in public chain transaction, and simultaneously provides a transparent and fair transaction environment which cannot be provided by a private chain. And the trading efficiency is improved, and the execution of the national real-name legal rules in the digital asset trading process is ensured.

Example 2:

the first step is as follows: the storing of the real name information may specifically include:

an intelligent contract is created that, when created, produces contract information that is stored in a blockchain generated by the blockchain.

Constructing a set of data structures (key-value pairs, the main key is the registration email, and the value is the data structure) of real-name information, wherein the data structure defines the following attributes including but not limited to: user name, gender, birthday, valid certificate type, valid certificate number, valid certificate photo, registration time, block transfer address (one key-value pair set, contract addresses of different types of digital assets correspond to different transfer addresses), authentication mailbox, and registration cell phone number.

When registering, the real name information is stored and stored in the block through the intelligent contract.

The second step is that: generating the transfer address may include:

the generated hash address, for example:

"0 x5127f78B7f22405c4248ad08865B553A0d053 bBD", where "0 x" is a fixed prefix indicating that the address may be a hash address corresponding to a care-of address.

The third step: and digitally signing the transfer address, broadcasting the digitally signed transfer address and storing the digitally signed transfer address in an account book node of the blockchain network.

The fourth step: the addressing of the transfer address may specifically include:

the real name information of the user is stored in the storage space pointed to by the contract address in the form of a key-value pair.

"0 x254247d6735fa73036ef9e3b3a2bf1a18377a2e 2" is the contract address of a digital asset.

This real name information intelligent contract may be defined by the program querying the address through the function:

map realNameInfo; information of real name

function queryAddrss(string email,address contractAddress){

return realNameInfo [ email ] [ captaddress ] }// email address and contract address of the incoming authentication.

For example, the function queryaddress is a function of an email address of an incoming authentication and an output contract address. In the above function, "contract address" represents the contract address; "email" represents the aforementioned email address.

The operation of the digital signature may be as follows:

the signature is made using a symmetric encryption (AES) approach, e.g. using the hash address above, with the key test @163. com. The result after encryption is then:

“2y1SFEYvDipKOx4Ybe707R64v5D0U6xhzkwEfu1QrzWA6XIXn9vGgWNjENK0Lm6k”

the fifth step: verification of the digital signature may include: and encrypting the address plaintext according to the digital signature mode of the previous step and then comparing the encrypted address plaintext with the encrypted address.

Example 3:

as shown in fig. 8, the present example provides a block chain-based transfer method including:

transfer beginning:

selecting a target user of the transaction, which may correspond to the aforementioned selection forwarding party identifier;

judging whether the transfer addresses of the block chains are generated or not, if not, entering the step of generating the transfer addresses of the block chains, and if so, carrying out digital signature on the transfer addresses of the two parties;

verifying the digital signature by the blockchain miner node;

if the verification is successful, the blockchain miners pack the transaction information (corresponding to the transfer information);

if the verification fails, the transfer is finished. In some cases, the method further comprises: and sending a transfer failure prompt to a requester of the transfer request (namely the aforementioned transfer-out party), wherein the transfer failure prompt also sends a failure reason in some embodiments so as to improve the user experience.

And other block chain miners verify the digital signature of the transfer address, if the transfer address passes the verification, the transfer is successful, and the transfer address is recorded into the transfer block.

Example 4:

as shown in fig. 9, the present embodiment provides a blockchain network, which includes the following three blockchain nodes:

a policing node at least to perform a verification, the verification comprising: adding verification of a blockchain node, verifying an execution result and verifying identity information of a client side of a query blockchain; in some embodiments, the policing node is also used for policing work for blockchains; the execution result here may include: the execution results of various business logics in the transfer process;

the miner nodes are used for participating in various calculations and forming execution results which can be added into the block chain;

and the account book node is used for recording the execution result verified by the supervision node, generating and storing the block chain and also used for inquiring the block chain.

In this example, the functions of the blockchain nodes are separated, and each middle blockchain node is responsible for different functions; therefore, on one hand, the problems that a single block chain link point needs to simultaneously bear multiple roles, so that the performance requirement on the block chain link point is high, and the software and hardware resource requirements on the block chain link point are high can be avoided, and the problems that the selection difficulty of the block chain node is high and the block chain network is difficult to build are solved. On the other hand, as the roles of the blockchain nodes are separated by the blockchain network, the function separation of the blockchain link points is realized, the work types required to be completed by a single blockchain link point are reduced, the load rate of the single blockchain node is reduced, and the response rate of the whole blockchain network is greatly improved.

In this example, the supervisory node, the mineworker node, and the ledger node are relatively independent nodes; for example, any two of the supervision node, the miner node and the book node are set on different physical devices, or correspond to virtual devices provided with a cloud platform; therefore, the functions of each node can be ensured to have enough separation degree, so that the performance requirement on single equipment is reduced, the building of a block chain network is simplified, and the problem of low response speed caused by excessive load accumulation of the single equipment is avoided.

In this example, the storage logic and the data operation logic of the ledger node are separate and independent from each other. Therefore, through decoupling of the storage logic and the data operation logic, the account book node can automatically plan data storage, can store data into offline equipment or network equipment, is not limited to the account book node, and can delete some blocks which are not used for a long time so as to save the consumption of storage resources; or, some data which is not queried for a long time is compressed, and the consumption of storage resources can be saved.

In this example, the blockchain network may be a federation blockchain network, and the blockchain may be a federation blockchain generated by the federation blockchain network. A federation chain is distinguished from a public chain that faces all the public and a private chain that faces only inside a certain community; the alliance chain faces a plurality of groups, on one hand, compared with the private chain, the transparentization of data supervision is realized, and the safety of data is ensured; and on the other hand, the coalition chain supervision is simpler and more convenient compared with a public chain.

The storing the block chain with storage logic independent of the data operation logic, comprising at least one of:

deleting the block data meeting a first preset condition in the block chain;

and storing the blocks meeting a second preset condition in the block chain into a preset storage device, wherein the preset storage device is an offline device or a network device independent of the ledger node.

The block data satisfying the first preset condition may include at least one of:

block data of which the time length from the current time reaches a first preset time length, although when partial data is deleted by each account book node, other account book nodes can store complete data;

the tile data of the digital assets that have currently been destroyed or withdrawn is deleted.

By deleting the block data, the storage resources required for storing the block chain can be reduced.

In some embodiments, deleting the block data may be at a granularity of the block data, or may be at a granularity of the block, which may simplify deletion.

For example, some blocks are dumped to offline devices or network devices, thereby reducing the storage resources required to be provided by the ledger node itself.

The blocks satisfying the second preset condition may include at least one of:

the time length from the current time reaches a block of a second preset time length; optionally, the second preset time length is less than the first preset time length;

blocks of digital assets that have currently been destroyed or withdrawn are transferred.

Optionally, characterized in that the method further comprises:

receiving a block chain query request sent by a client;

receiving a verification result of the identity information of the client terminal broadcast by the supervision node;

and if the identity information of the client passes the verification, responding to the block chain query request.

In this example, authentication of the blockchain query request is performed by the supervisory node, and as such, the ledger node may reduce the amount of workload, thereby reserving more resources to respond to blockchain queries and blockchain generation and storage.

The block data here may include data generated in the aforementioned transfer.
