Technical Field
The present invention relates to the field of networks, and in particular, to a resource transaction method and apparatus based on a block chain technique.
Background
With the development of internet technology, resources in the form of data have been presented in a rich variety. At present, resource transactions mostly operate in a centralized and non-point-to-point mode, that is, all transaction information is uniformly mediated and stored through a transaction center, and if the transaction center is not trusted, such as the situations that a database is hacked, transaction data is artificially tampered, and the like, the transaction information is possibly maliciously tampered and is difficult to obtain evidence.
In order to solve the problems, a transaction mode based on a block chain technology is provided, the problems of centralized and non-point-to-point transactions are solved to a certain extent, but due to the fact that only a single transaction block chain is used, along with the gradual increase of transaction participants and the monopolization of a large number of intelligent contracts to computing resources, the transaction chain becomes mixed and bloated in content, and the risk of sudden performance bottleneck occurs in the peak period of transaction, so that the efficiency of the whole transaction block chain is influenced. In addition, as the transaction occurs in a public transaction block chain, the resource issuer basically has no controllability on the transaction safety, and certain potential safety hazard exists for resources with private transaction requirements.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples. Non-conflicting ones of the following embodiments may be combined with each other.
As shown in fig. 1, a first embodiment of a resource transaction method based on the blockchain technique of the present invention includes:
s1: the electronic device receives digital currency for payment of the user transaction address over the first blockchain.
The electronic device is a fixed or mobile device, such as a computer, a mobile phone, a tablet, a server, etc., connected to a network. The electronic device may include a processor and a memory, the memory storing instructions for composing a transaction application for implementing resource transactions, the processor may execute the instructions to run the transaction application to implement the method provided by the present embodiment.
Typically, a user initiates a payment transaction using an application end (e.g., a first blockchain wallet) having access to a first blockchain to transfer a specified amount of digital currency equivalent to a resource price in a user transaction address to the first transaction address of the transaction application. On the first block chain, the user transaction address belongs to a user, namely a requirement main body in resource transaction; the first transaction address belongs to a resource issuer (or resource provider, i.e., the supplier in a resource transaction).
Both the application side and the transaction application may run on the electronic device. The application terminal may also be run on another terminal different from the electronic device, the terminal and the electronic device being communicatively connected. Of course the user may also directly use the transaction application to initiate a payment transaction.
The transaction application may or may not be issued by the resource issuer. If the transaction application is issued by the resource issuer, the resource issuer may register information and access/download links of the transaction application on the first blockchain to which the registration information is submitted in a transactional manner. The application end can obtain the registered transaction application program information by scanning the first blockchain, and the registered transaction application program information is displayed in a tradable resource list for the user to select, and each table entry is linked to the corresponding transaction application program.
Blockchain technology is a new decentralized infrastructure and distributed computing paradigm that utilizes an encrypted chained blockstructure to verify and store data, a distributed node consensus algorithm to generate and update data, and automated script code to program and manipulate data. The core advantage of the blockchain technology is decentralization, and point-to-point transaction, coordination and cooperation based on decentralization credit can be realized in a distributed system with nodes not needing to trust with each other by means of data encryption, timestamps, distributed consensus and the like, so that a solution is provided for solving the problems of high cost, low efficiency, unsafe data storage and the like commonly existing in a centralization mechanism.
The first blockchain is distributively stored in a first blockchain network, and the first blockchain network is a multi-node network system formed by utilizing blockchain technology. The electronic device may or may not belong to the first blockchain network. If the electronic device does not belong to the first blockchain network, a node of the blockchain network to which the electronic device is connected, which is connected to at least one node of the first blockchain network, may be referred to as a first connection node.
S2: the electronic device transfers digital currency from the first blockchain to the second blockchain through a bidirectional anchoring protocol between the first blockchain and the second blockchain.
The bi-directional anchoring protocol refers to that value of digital currency can be transferred bi-directionally between the first blockchain and the second blockchain. The accounting nodes of the first blockchain and the second blockchain are respectively incorporated with a bidirectional anchor protocol code, and the verification of the digital currency during the transfer between blockchains can be executed according to the bidirectional anchor protocol to determine whether the transfer of the digital currency is accepted.
Similarly, the second blockchain is distributively stored in a second blockchain network, which is a multi-node network system composed by using blockchain technology. The electronic device may or may not belong to the second blockchain network. If the electronic device does not belong to the second blockchain network, the node of the blockchain network to which the electronic device is connected, which is connected to the at least one node of the second blockchain network, may be referred to as a second connection node.
After the transfer is completed, the transaction application program may not use the specified amount of digital money in the first transaction address on the first blockchain, and the transaction application program may add a corresponding amount of tokens to the second transaction address on the second blockchain as the transferred digital money.
S3: the electronic device pays the transferred digital currency to the interface address of the smart contract on the second blockchain.
In particular, the electronic device may forward tokens at the second transaction address to an interface address of the smart contract.
The intelligent contract is a core constituent element (contract layer) of the block chain, is a computer program which is driven by events, has a state and runs on a reproducible shared block chain data book, and can realize the functions of actively or passively processing data, receiving, storing and sending values, controlling and managing intelligent assets on various chains and the like. In particular, an intelligent contract is a set of scenario-correspondence type programming rules and logic, which is decentralized, trusted, shared program code deployed on a blockchain. The smart contracts also have the general characteristics of blockchain data, such as distributed recording, storage and verification, non-falsification and forgery. After the parties signing the contract agree on the contract content, the contract is deployed on the block chain in the form of an intelligent contract, and the contract can be automatically executed on behalf of the signing parties without any central authority.
In general, the second blockchain may be a blockchain deployed or approved by a resource issuer. The intelligent contract may be pre-deployed on the second block chain by the resource issuer, and after the intelligent contract is deployed, the second block chain may generate an interface address of the corresponding intelligent contract according to the function of the intelligent contract for access. The content of the smart contract may include: the resource content or the obtaining mode, the resource price, the triggering condition of the intelligent contract execution and the transaction content executed by the intelligent contract.
If the resource issuer provides more than one resource, different intelligent contracts may be deployed for different resources, although one intelligent contract may be used for trading of multiple resources.
S4: and the electronic equipment receives the resources returned by the intelligent contract interface address or the acquisition mode of the resources on the second blockchain and acquires the digital currency on the first blockchain through the bidirectional anchoring protocol.
The triggering condition for the execution of the intelligent contract in this embodiment may include the receipt of a certain amount of tokens, and the contents of the transaction executed by the intelligent contract may include the return of the resource or the manner of acquisition of the resource to the second transaction address on the second blockchain, and the transfer of the received tokens from the second blockchain back to the first blockchain, thereby enabling the electronic device to acquire the specified amount of digital currency on the first blockchain.
After receiving the resource or the resource acquisition mode, the electronic device may show the resource or the resource acquisition mode to the user, for example, display the resource content or the resource acquisition mode in a visual interface of the transaction application. If the received resource acquisition mode is the format of the link address, the resource acquisition mode can be directly jumped to the address.
In order to ensure the realization of point-to-point transactions of decentralized credit on the blockchain, after each transaction, the electronic device submits the processing result of the transaction to the corresponding first/second blockchain network, so that the node of the first/second blockchain network stores the processing result of the transaction in the first/second blockchain.
Specifically, if the electronic device belongs to the first/second blockchain network, the processing result can be directly submitted to the first/second blockchain network in a broadcast manner; if the electronic device does not belong to the first/second blockchain network, the processing result can be sent to the first/second connection node, and then the processing result can be submitted to the first/second blockchain network in a mode of broadcasting to the first/second blockchain network by the first/second connection node. After the accounting nodes of the first/second block chain network achieve consensus, the processing result of the transaction is recorded to a new block, and the block is accessed into the first/second block chain, so that the processing result of the transaction is stored in the first/second block chain by the nodes of the first/second block chain network.
Through the implementation of the embodiment, two block chains achieving a bidirectional anchoring protocol are used for completing resource transaction, the payment of the transaction is completed on the first block chain, the actual execution of the transaction is completed on the second block chain, the payment and execution decoupling of the transaction is realized, the problem of centralized and non-point-to-point transactions is solved, the possibility of performance bottleneck of a single block chain is effectively reduced, the execution of the transaction only occurs on the second block chain, resources only circulate on the second block chain, the circulation range is reduced, and the potential safety hazard is reduced.
As shown in fig. 2, a second embodiment of the resource transaction method based on the blockchain technology of the present invention is based on the first embodiment of the resource transaction method based on the blockchain technology of the present invention, and specifically defines a transfer process of digital money between blockchains. This embodiment is a further extension of the first embodiment of the resource transaction method based on the blockchain technology, and therefore, the same contents as those in the first embodiment of the resource transaction method based on the blockchain technology are not described herein again. The embodiment comprises the following steps:
s11: the electronic device receives digital currency for payment by the user transaction address using the first transaction address on the first blockchain.
S12: the electronic device constructs a first locked transaction on the first blockchain to lock digital currency in a first transaction address.
The locked digital currency is not available.
S13: the electronic device references the first locked transaction and the payment verification for the first locked transaction on the second blockchain.
The payment verification of the first locked transaction includes: the first locked transaction has been recorded in a first block of the first block chain, and a number of valid blocks following the first block in the first block chain is greater than a first threshold.
The valid blocks after the first block may also be referred to as first protected blocks, the role of which is to ensure that the recording of the first locked transaction is truly valid. The accounting node of the second blockchain stores the bidirectional anchoring protocol code, so that the first locked transaction referenced by the electronic equipment can be checked, and the payment verification of the first locked transaction is completed if the checking is successful.
As shown in fig. 3, in an embodiment of the present invention, S13 may specifically include:
s131: the electronic device submits the referenced first locked transaction to the second blockchain network.
S132: the accounting node of the second blockchain network checks whether the first locked transaction has been recorded in the first block of the first blockchain by the bidirectional anchoring protocol and the number of valid blocks after the first block in the first blockchain is greater than a first threshold.
If the inspection is successful, the subsequent steps are performed, and if the inspection is unsuccessful, the electronic device may perform S131 again. Optionally, the electronic device may wait for a period of time before performing S131 again to reduce the number of repeated submissions.
To avoid duplicate submissions, as shown in fig. 4, in another embodiment of the present invention, S13 may specifically include:
s134: the electronic device checks on the first block chain whether the first locked transaction has been recorded in a first block of the first block chain, and the number of valid blocks after the first block in the first block chain is greater than a first threshold.
In this embodiment, the electronic device has the capability of identifying the consensus mechanism of the first blockchain and the second blockchain, and is used for payment verification of the locked transaction when digital currency is transferred between the chains. If the verification is successful, the payment verification of the first locking transaction is completed, and S135 is skipped; if not, S134 is repeatedly executed.
S135: the electronic device submits the referenced first locked transaction to the second blockchain network.
S136: the accounting node of the second blockchain network checks whether the first locked transaction has been recorded in the first block of the first blockchain by the bidirectional anchoring protocol and the number of valid blocks after the first block in the first blockchain is greater than a first threshold.
And after the electronic equipment completes the checking, the accounting node of the second block chain network successfully checks and executes the subsequent steps.
S14: after consensus by the accounting node of the second blockchain, the electronic device obtains a corresponding amount of tokens on the second blockchain as transferred digital currency using the second transaction address.
The electronic device obtains the amount of tokens on the second blockchain corresponding to the amount of digital currency locked on the first blockchain, for example, the amount of tokens is the same as or proportional to the amount of digital currency.
S15: the electronic device pays the transferred digital currency to the interface address of the smart contract on the second blockchain.
S16: and the electronic equipment receives the resource returned by the intelligent contract interface address or the acquisition mode of the resource on the second block chain.
The execution sequence between this step and S17-S19 is merely illustrative, and may be actually exchanged or executed simultaneously.
S17: the electronic device obtains information that intelligently closes a second locked transaction constructed on a second blockchain.
The second lock transaction is to lock a token in a second blockchain, the locked token not being available.
S18: the electronic device references the second locked transaction and the payment verification for the second locked transaction on the first blockchain.
The payment verification of the second locked transaction includes: the second lock transaction has been recorded in a second block of the second block chain, and a number of valid blocks following the second block in the second block chain is greater than a second threshold.
Similarly, the valid blocks after the second block may also be referred to as second protection blocks, which function to ensure that the record of the second lock transaction is truly valid. The accounting node of the first blockchain stores the bidirectional anchoring protocol code, so that the second locked transaction referenced by the electronic equipment can be checked, and the payment verification of the second locked transaction is completed if the checking is successful. The first threshold and the second threshold may be the same or different.
As shown in fig. 5, in an embodiment of the present invention, S18 may specifically include:
s181: the electronic device submits the referenced second locked transaction to the first blockchain network.
S182: the accounting node of the first blockchain network checks whether the second locked transaction has been recorded in a second block of the second blockchain by the bidirectional anchoring protocol, and the number of valid blocks after the second block in the second blockchain is greater than a second threshold.
If the inspection is successful, the subsequent steps are performed, and if the inspection is unsuccessful, the electronic device may perform S181 again. Optionally, the electronic device may wait for a period of time before performing S181 again to reduce the number of repeated submissions.
To avoid duplicate submissions, as shown in fig. 6, in another embodiment of the present invention, S18 may specifically include:
s184: the electronic device checks on the second blockchain whether the second locked transaction has been recorded in a second block of the second blockchain, and the number of valid blocks after the second block in the second blockchain is greater than a second threshold.
In this embodiment, the electronic device has the capability of identifying the consensus mechanism of the first blockchain and the second blockchain, and is used for payment verification of the locked transaction when digital currency is transferred between the chains. If the verification is successful, the payment verification of the second locking transaction is completed, and the step is shifted to S185; if not, S184 is repeatedly executed.
S185: the electronic device submits the referenced second locked transaction to the first blockchain network.
S186: the accounting node of the first blockchain network checks whether the second locked transaction has been recorded in a second block of the second blockchain by the bidirectional anchoring protocol, and the number of valid blocks after the second block in the second blockchain is greater than a second threshold.
And after the electronic equipment completes the checking, the accounting node of the first block chain network successfully checks and executes the subsequent steps.
S19: after consensus by the accounting node of the first blockchain, the electronic device unlocks the digital currency in the first transaction address on the first blockchain.
After unlocking, the digital currency becomes available and the resource transaction is completed.
As shown in fig. 7, a third embodiment of the resource transaction method based on the blockchain technique according to the present invention is based on the first embodiment of the resource transaction method based on the blockchain technique according to the present invention, and S1 includes:
s101: the electronic device receives a payment request.
The payment request may be made by the user via an input device (e.g., a touch screen, a keyboard, a microphone, etc.) of the electronic device, or may be made remotely by the user via another device.
S102: the electronic device determines whether the balance in the user's transaction address is greater than or equal to the price of the resource.
If the balance is larger than or equal to the price of the resource, the user can pay the full amount, and the step S103 is skipped; if the balance is less than the price of the resource, it indicates that the user can not pay the full amount, and it goes to step S104.
S103: the electronic device initiates a payment transaction to transfer from the balance a digital currency equivalent to the price of the resource to the first transaction address and submits a processing result of the payment transaction to the first blockchain network.
The nodes of the first blockchain network store the results of the processing of the payment transaction in the first blockchain. The detailed process can refer to the related description in the first embodiment of the resource transaction method based on the blockchain technology.
S104: the electronic device denies the payment request.
