Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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.

The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The inventors of the present application have found, through long-term research: in the current blockchain project, there are many problems in carrying out blockchain transactions between blockchain link points. The transactions spontaneously performed by the two parties in the block chain lack credible guarantee, and some malicious transactions not only easily cause property loss and privacy disclosure of the parties, but also reduce the transaction efficiency of the block chain. Invalid transactions also waste the computation power of blockchain nodes in the blockchain system, and affect the normal operation of the blockchain system. As the blockchain is developed, the maintenance of the blockchain system consumes more capital, and the capital for maintaining the blockchain system is less and less, which is not only disadvantageous to the development of the blockchain system, but also may cause the breakdown of the blockchain system network. To solve these problems, the present application proposes at least the following embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the present invention. The blockchain system 100 of the present embodiment includes a trading platform 101, a management platform 102, and blockchain nodes 103.

The trading platform 101 may provide a trusted trading channel for both trading parties. When the blockchain transaction is performed, the blockchain node 103 may transfer the transaction funds to the transaction platform 101, and the transaction platform 101 may keep the transaction funds and distribute the transaction funds after the transaction is completed. The transaction platform 101 may also collect selling or purchasing information of goods or services on the blockchain, and push the information to corresponding demanders or buyers, so as to facilitate transactions between the blockchain nodes 103 and improve transaction efficiency.

The blockchain system 100 of the present embodiment may include one or more trading platforms 101, and different trading platforms 101 may trade in the same digital currency or may trade in corresponding digital currencies respectively. Transactions conducted between the various transaction platforms 101 may be isolated from each other to protect privacy and security of the transactions. The plurality of trading platforms 101 can also alleviate the situation of low trading efficiency caused by high concurrency of data in the blockchain system 100, which is beneficial to improving the trading efficiency. Blockchain node 103 may participate in transactions for multiple trading platforms 101.

The trading platform 101 may also deploy corresponding intelligent contracts, which may be used to specify trading rules for blockchains or allocation rules for trading funds. When conducting the blockchain transaction, the transaction platform 101 may execute a corresponding intelligent contract to conduct the transaction or allocate transaction funds, so that human intervention may be reduced, and the reliability of the blockchain transaction may be improved.

In some embodiments, the trading platform 101 may further provide an information publishing interface, and the block link node 103 may publish the goods or services information through the information publishing interface to perform the trading. For example, the buyer node may issue a purchase demand to the transaction platform 101, the seller node obtains the transaction demand and then performs matching, and if the purchase demand is met, the transaction platform 101 may perform transaction with the buyer node. Alternatively, the seller node may publish the offered goods or services to the transaction platform 101, and the buyer node may initiate a transaction to the seller node through the transaction platform 101 upon purchase. The transaction platform 101 may also notify the seller node to provide the corresponding goods or services after receiving the transaction information of the buyer node.

In this embodiment, the blockchain node 103 performs a transaction through the transaction platform 101, and the transaction platform 101 may also collect a corresponding commission fee from the transaction funds for governing the transaction platform 101, so as to maintain safe and stable operation of the transaction platform 101. The transaction platform 101 may also verify the identity legitimacy of both parties during the transaction, and perform the transaction only when both parties are legitimate, otherwise, terminate the transaction, so as to ensure the security of the transaction. In addition, the transaction is carried out through the transaction platform 101, and the two transaction parties do not need to know the identity of the other transaction party in the transaction process, so that the privacy and the safety of the two transaction parties are protected.

In this embodiment, the management platform 102 may manage the fund collection and payment of the blockchain system 100. The fund collection and payment of the blockchain system 100 are performed through a common account configured by the blockchain system 100, and the fund in the common account can be used for the governance of the blockchain. The management platform 102 may enable management of the funds charges for the blockchain system 100 by managing common accounts. For example, the management platform 102 may place the collected transaction funds for the blockchain transaction into a common account and withdraw funds from the common account for use in administering the blockchain. The management platform 102 may be a particular node or organization thereof in the blockchain system 100. For example, the management platform 102 may be selected nodes with stable operation and high credibility in the blockchain system 100, and these nodes may collectively manage the fund collection and payment of the blockchain system 100.

The management platform 102 may perform management operations such as transfers, collections, payments, checks, etc. of funds for the blockchain system 100 to maintain a steady development of digital currency in the blockchain system 100. For example, the management platform 102 may collect a portion of the transaction funds for the blockchain transaction that may be used as a commission provided by the blockchain node 103 for administration of the blockchain system 100 to maintain stable and sustainable development of the blockchain system 100.

The management platform 102 may also set up a corresponding account for storing funds for the blockchain system 100. The management platform 102 may place the received transaction funds into the corresponding account for custody. For example, the management platform 102 may place transaction funds into corresponding types of accounts according to the types of funds, so as to respectively manage multiple types of transaction funds; or the management platform 102 may place the transaction funds transacted on different transaction platforms 101 into different accounts to achieve fund isolation for different transaction platforms 101.

In this embodiment, the blockchain system 100 provides a trusted transaction channel for blockchain transactions through the cooperation of the management platform 102 and the transaction platform 101, and performs trusted allocation on transaction funds, which is beneficial to improving the security of blockchain transactions.

The management platform 102 may also preset corresponding intelligent contracts for specifying rules for the fund balance of the blockchain system 100. For example, the management platform 102 may perform management operations such as collection, payment, or verification of funds by executing an intelligent contract, which is beneficial to reduce human intervention and improve the security of the funds and the reliability of the funds management of the blockchain system 100.

In some embodiments, the management platform 102 may also be the trading platform 101, and at this time, the management platform 102 in the blockchain system 100 may serve as the trading platform 101 to provide a corresponding trading channel for blockchain trading and manage allocation of trading funds. In this embodiment, the blockchain system 100 includes a management platform 102 and blockchain link points 103. The management platform 102 may implement the functions of the trading platform 101, and the trading involving the block link points 103 may be performed through the management platform 102.

In this embodiment, the blockchain node 103 may participate in a transaction in the blockchain network, and may obtain a corresponding good or service by paying out transaction funds, or obtain a corresponding fund payment by paying out the good or service. There are multiple blockchain nodes 103 that may participate in blockchain transactions via the transaction platform 101. When the blockchain node 103 conducts transaction through the transaction platform 101, the transaction platform 101 provides a credible transaction guarantee without acquiring the identity of the other party, so that the privacy and the safety of both parties of the transaction can be effectively protected.

The blockchain node 103 can also participate in transactions such as endorsement, sorting, block packaging, communication or accounting of the blockchain, and can also obtain corresponding compensation by participating in the blockchain transactions. For example, the blockchain node 103 may obtain a corresponding funding reward by participating in the packaging of the blocks, or obtain a corresponding endorsement funding reward by an endorsement of the transaction; the blockchain node 103 may participate in the blockchain transaction with the accumulated funds as transaction funds.

In this embodiment, the blockchain link point 103 may also include a light node, and the light node may participate in the blockchain transaction, and the transaction platform 101 may transfer the transaction information and the transaction fund, and store the blockchain data related to the transaction itself after the transaction is completed, without synchronizing the complete blockchain ledger, so that the calculation effort may be saved, and the transaction efficiency of the blockchain link point 103 may be improved.

In the blockchain system 100 of the embodiment, the trading platform 101 is arranged to provide a credible trading channel, and the trading funds of the trading party can be transferred to the trading platform 101 and then distributed by the trading platform 101, so that property loss caused by malicious trading to the trading party is effectively reduced, the safety and reliability of trading are improved, and the trading platform 101 is used for trading, so that direct contact between two trading parties can be avoided, and the privacy and safety of the two trading parties can be protected; the management platform 102 on the blockchain may be used to administer the blockchain system 100 by collecting a portion of the transaction funds, which is beneficial to promote stable and sustainable development of the blockchain system 100.

Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a transaction method of a blockchain according to the present application. The embodiment comprises the following steps:

s101: the first node sends the transaction information and the transaction funds to the transaction platform.

In this embodiment, the first node may be any blockchain node in the blockchain system. The first node is used as a demand party and participates in the blockchain transaction, and corresponding goods or services and the like are obtained through expenditure of funds. The first node may communicate with the transaction platform, send transaction information for purchasing the goods or services to the transaction platform, and pay corresponding transaction funds to the transaction platform, thereby performing a blockchain transaction.

In this embodiment, the transaction information may include addresses of both parties of the transaction, transaction time, transaction amount, commodity or service of the transaction, other related information, and the like. The transaction information may also be a single party of transaction information. For example, the transaction information is sent by the demanding party to the transaction platform, and may include an address of the demanding party, a transaction amount, information related to the required goods or services, and the like. After the first node sends the transaction information to the transaction platform, the transaction platform can search a proper transaction party according to the transaction information to carry out transaction.

In this embodiment, the transaction funds are funds that the first node pays based on the value of the goods or services purchased. The total amount of the transaction fund is not less than the corresponding transaction amount in the transaction. The first node can complete payment once or pay by stages when paying the transaction funds. When the first node carries out the blockchain transaction, transaction funds can be paid to the transaction platform in advance, and the transaction platform carries out fund keeping. After receiving the transaction funds, the transaction platform may verify whether the transaction funds meet the specifications, for example, whether the transaction funds are sufficient, whether the transaction funds are valid and valid, and the like, and if the transaction funds meet the specifications, the transaction is continued.

S102: the trading platform generates a trading contract based on the trading information.

In this embodiment, the transaction platform may provide a blockchain transaction channel. The trading platform is provided with corresponding intelligent contracts, and after the trading information is received, the trading contracts of the trades can be generated by calling the intelligent contracts on the block chain.

The smart contracts may be used to specify rules for blockchain transactions. For example, the relevant rules include the term of the transaction, the execution mode, the processing method of the incomplete transaction, and the like. The smart contract may also specify rules for payment or distribution of the transaction funds, including, for example, payment methods for the transaction funds, payment addresses, proportions of payments made to the seller and the transaction platform and/or management platform, payment times, and the like.

When the first node conducts transaction, the transaction information is sent to the transaction platform to request for conducting transaction. The transaction platform can also verify the correctness and validity of the transaction information after receiving the transaction information. For example, the transaction platform may verify that the transaction information format is correct, the information is complete, the identity or address of the parties to the transaction is legitimate, the number of funds in the transaction is correct, etc. The transaction platform can call the intelligent contract to generate a corresponding transaction contract when the transaction information is verified to be correct and legal.

S103: the trading platform executes the trading contract to transfer at least a portion of the trading funds to the second node.

The second node may be any blockchain node in the blockchain system, and the second node may be a supplier, participate in the blockchain transaction, obtain a corresponding reward by providing goods or services, and the like. The second node may communicate with the trading platform, provide corresponding goods or services to the first node upon receiving a trading message from the trading platform, and obtain corresponding trading funds. In some embodiments, the second node may also issue the provided goods or services to the trading platform in advance, the trading platform notifies the second node to trade when receiving the corresponding trading demand of the first node, and the second node may obtain corresponding trading funds after executing the trade.

In this embodiment, the trading platform may execute the trading contract to transfer at least a portion of the trading funds to the second node when both parties to the trade complete the trade. For example, the trading platform may pay the corresponding trading funds to the second node as specified by the trading contract when the first node receives goods or services for the second node and confirms that the trade is completed. Alternatively, the trading platform may execute a trading contract at an agreed time to effect the allocation of trading funds. For example, the trading platform may pay the corresponding trading funds to the second node at a predetermined time, such as eight days or ten days, after receiving the trading contract.

The transaction platform transfers at least a portion of the transaction funds to the second node, which may be a full payment of the transaction funds to the second node. Or the trading platform can pay corresponding partial trading funds to the second node according to the distribution proportion of the trading funds in the trading contract, and the rest trading funds can be transferred to the management platform to be used for governing the block chain system. For example, the trading platform may also perform the following step of S104.

S104: the trading platform transfers at least a portion of the remaining trading funds to the management platform.

In this embodiment, the management platform may be used to manage the fund balance of the blockchain system. The funds collected by the management platform can be used for governing the blockchain system so as to maintain the stable operation of the blockchain system. The trading platform may pay the portion of the trading funds to the second node after the trading is completed and transfer the remaining portion of the trading funds to the management platform. Or, the transaction platform may transfer part of the transaction funds to the management platform in advance after receiving the transaction funds, and pay the corresponding transaction funds to the second node when the transaction is completed.

The transaction platform transfers part of transaction funds to the management platform, so that the funds for managing the block chain system can be continuous, the normal operation of the block chain is not influenced by the exhaustion of the funds, and the healthy, stable and sustainable development of the block chain is facilitated. In some embodiments, when the management platform is integrated with the trading platform, the trading platform may reserve the remaining trading funds for administering the blockchain system.

In some embodiments, the trading platform may also collect certain commission fees from the blockchain trading for the governance of the trading platform to maintain the safe and stable operation of the trading platform. For example, the trading platform may also perform the following step S105.

S105: the trading platform collects at least a portion of the remaining trading funds for use with the administering trading platform.

The transaction platform provides a credible transaction channel for transactions in the block system, so that the block chain nodes can perform transactions through the transaction platform when participating in the block chain transactions, the transaction platform can also receive transaction funds and provide temporary storage service for the transaction funds before the transactions are distributed, the security of the transaction funds is protected, and the fund loss caused by malicious transactions is reduced. In order to maintain the stable operation of the trading platform and provide a safer and more reliable trading channel, the trading platform can collect partial commission fees from trading funds for the governance of the trading platform.

In this embodiment, the trading platform may pay part of the trading funds to the second node after the trading is completed, and leave part of the remaining trading funds for governing the trading platform. Or, the transaction platform may take out part of the transaction funds in advance for standby after receiving the transaction funds, and pay the rest of the transaction funds to the second node when the transaction is completed.

In this embodiment, the steps of S104 and S105 may be executed only or may be executed both, and the execution order is not limited. For example, the transaction platform may pay a portion of the transaction funds to the second node, leave the remaining transaction funds or transfer the remaining transaction funds to the management platform; or the transaction platform can pay part of the transaction funds to the second node, reserve part of the remaining transaction funds, and transfer the other part of the remaining transaction funds to the management platform, namely, one part of the transaction funds in the blockchain is used for governing the transaction platform, and the other part of the transaction funds is used for governing the blockchain system, so that stable operation of the transaction platform and the blockchain is maintained.

In this embodiment, the sequence of steps S101 to S105 is the description sequence in this embodiment, and is not limited to the sequence of the transaction method of the block chain in this embodiment in the execution process, and on the premise that the method can be implemented, some steps may be executed simultaneously or individually by exchanging the sequence.

Referring to fig. 3, fig. 3 is a schematic flow chart of a transaction method of the blockchain of the present application according to a second embodiment. This embodiment is further described on the basis of the first embodiment of the block chain transaction method of the present application, and the same steps as those in the first embodiment of the block chain transaction method of the present application are not described herein again. The embodiment comprises the following steps:

s201: the first node sends the transaction information and the transaction funds to the transaction platform.

S202: the trading platform generates a trading contract based on the trading information.

S203: the transaction platform forms a transaction notification message based on the transaction information and sends the transaction notification message to the second node.

After the transaction platform receives the transaction information of the first node, a transaction notification message can be formed based on the transaction information. In this embodiment, the transaction notification message may include information of the goods or services being transacted, information related to the first node, transaction time limit, transaction amount, other related information, and the like. The transaction platform may extract relevant information in the transaction information and form a transaction notification message after receiving the transaction information. The transaction platform sends the transaction notification message to the second node so that the second node can execute the transaction in time.

In this embodiment, the first node sends the transaction information to the transaction platform, and the transaction platform notifies the second node to perform the transaction, so that direct contact between two parties of the transaction can be avoided, privacy and safety of the two parties of the transaction are protected, the transaction platform can provide reliable keeping of transaction funds, and security of the transaction funds of the first node is protected.

S204: the second node executes the transaction according to the transaction notification message.

When the second node receives the transaction notification message, the second node can provide corresponding goods or services to the first node within a specified time according to the transaction content in the transaction notification message.

In this embodiment, when the transaction is completed, the transaction platform may allocate transaction funds according to the rules of the transaction contract, such as performing the following steps S207-S209. Or after the transaction platform notifies the second node to perform the transaction, whether the transaction is completed correctly can be judged, so that whether the transaction fund is distributed or not is determined. For example, the trading platform may also perform the following steps of S205 or S205-S206 before allocating the trading funds.

S205: the trading platform judges whether a trading completion message is received within a first preset time.

In this embodiment, after notifying the second node to execute the transaction, the transaction platform may determine whether the transaction is completed by determining whether a transaction completion message of the first node is received. The transaction platform may time the transaction, for example, start timing when the transaction information is received, or start timing when the transaction notification message is sent to the second node, and then determine whether the transaction completion message from the first node is received within a first preset time after the timing is started. The first preset time is, for example, seven days or ten days, and if the transaction platform receives the transaction completion message of the first node within the first preset time, it may be determined that the transaction is completed correctly.

In this embodiment, the transaction completion message may include information related to the execution time, completion degree, and the like of the transaction. The transaction platform may also pay the corresponding transaction funds to the second node according to the completion condition of the transaction in the transaction completion message, such as the completion degree, when receiving the transaction completion message. For example, if the transaction completion message sent by the first node to the transaction platform indicates that the second node has completed only part of the transaction, the transaction platform may pay the corresponding part of the transaction funds to the second node after confirmation; the transaction platform can also return the transaction funds corresponding to the incomplete partial transaction to the first node, or pay the corresponding transaction funds to the second node when subsequently receiving the transaction completion message of the remaining partial transaction.

In this embodiment, if the trading platform receives a trading completion message from the first node within a first preset time, the following steps S207 to S209 may be executed to allocate the trading funds; if the trading platform does not receive the trading completion message from the first node within the first preset time, the following step S207 may not be executed, or the trading platform may further determine whether the trading is cancelled, for example, the following step S206 may be executed.

S206: and the trading platform judges whether a trading cancellation message is received within a second preset time.

In this embodiment, if the transaction platform does not receive the transaction completion message of the first node within the first preset time, it may further determine whether the transaction cancellation message is received within the second preset time, so as to determine whether the transaction is cancelled. The transaction cancellation message may include information about the reason for the transaction cancellation, the cancellation time, and the like. The transaction cancellation message may be sent by the first node or the second node to the transaction platform when the transaction is cancelled.

In this embodiment, the second preset time is greater than the first preset time. The transaction platform may time the transaction, for example, from receipt of the transaction message or from sending a transaction notification message to the second node. The first preset time and the second preset time can adopt the same timing mode, and the second preset time is greater than the first preset time. For example, the first preset time is seven days, the second preset time may be ten days, and if the transaction platform does not receive the transaction completion message within seven days, it is further determined whether the transaction cancellation message is received within ten days.

In this embodiment, if the transaction platform does not receive the transaction completion message in the first preset time, or does not receive the transaction cancellation message in the second preset time, the transaction platform may pay the corresponding transaction fund to the second node according to the specification of the transaction contract, for example, execute the following step S207; or the transaction platform may also confirm whether the transaction is completed to the first node and/or the second node to determine whether to perform the allocation of the transaction funds. If the trading platform receives the trading cancellation message of the first node or the second node within the second preset time, the trading platform determines that the trading is cancelled, and the following step S207 may not be executed any more. Alternatively, the trading platform may also refund the trading funds when the trade is cancelled, such as performing the following step S210.

S207: the trading platform executes the trading contract to transfer at least a portion of the trading funds to the second node.

In this embodiment, the transaction platform may further transfer at least a portion of the transaction funds to the second node within a third predetermined time after receiving the transaction completion message.

In this embodiment, if the management platform does not receive the transaction completion message of the first node within the first preset time, it may further determine whether the transaction cancellation message is received within the second preset time, so as to determine whether the transaction is cancelled. The transaction cancellation message may include information about the reason for the transaction cancellation, the cancellation time, and the like.

The transaction cancellation message may be from the first node, the second node, or the transaction platform. For example, when the first node or the second node cannot complete the transaction correctly, a transaction cancellation message may be sent to the management platform to cancel the transaction; or the first node or the second node sends a transaction cancellation message to the transaction platform when the transaction cannot be completed correctly, and the transaction platform sends the transaction cancellation message to the management platform after confirmation so as to cancel the transaction.

In this embodiment, the second preset time is longer than the first preset time. The first predetermined time and the second predetermined time may be timed in the same manner, for example, from the receipt of the trading contract by the management platform. For example, the first preset time is five days, the second preset time may be ten days, and if the management platform does not receive the transaction completion message within five days from the start of the transaction contract, it further determines whether the transaction cancellation message is received within ten days.

The first preset time and the second preset time in this embodiment are only used for description, and may be the same as or different from the first preset time and the second preset time in the second embodiment of the block chain transaction method in the present application.

In this embodiment, if the management platform does not receive the transaction completion message in the first preset time, or does not receive the transaction cancellation message in the second preset time, the management platform may pay the corresponding transaction fund to the second node according to the specification of the transaction contract, for example, execute the following step S406; or the management platform may also confirm completion of the transaction to the first node, the second node and/or the transaction platform to determine whether to perform allocation of the transaction funds. If the management platform receives the transaction cancellation message of the first node, the second node, or the transaction platform within the second preset time, the management platform determines that the transaction is cancelled, and may not execute the following step S406. In some embodiments, the management platform may also refund the transaction funds when the transaction is cancelled, for example, by performing the following step S409.

S406: the management platform executes the trading contract to transfer at least a portion of the trading funds to the second node.

In this embodiment, the management platform may also transfer at least a portion of the transaction funds to the second node within a third predetermined time after receiving the transaction complete message. The third preset time is, for example, one day or three days. The management platform performs the allocation of the transaction funds within the third preset time, and can provide a proper buffer time to ensure that the transaction is completed correctly. The third preset time in this embodiment is only used for description, and may be the same as or different from the third preset time in the second embodiment of the transaction method of the blockchain of the present application.

In some embodiments, the transaction funds received by the management platform can be used for other purposes within the time kept by the management platform to generate benefits, so that the flexibility of the management platform for transaction fund management can be effectively improved, and the benefits generated by the transaction funds can also be used for governing the blockchain system and maintaining the stable operation of the blockchain.

In this embodiment, when the transaction platform receives the transaction fund of the first node, the transaction fund can be completely transferred to the management platform. The management platform can also pay the transaction fund part to the second node according to the rules in the transaction contract, and use the remaining transaction fund part for the block chain or the governance of the transaction platform. For example, the management platform may perform the following steps S407 to S408.
