It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
The embodiment of the invention provides a transaction method for a blockchain system. The method may be performed by a transaction device for a blockchain system, wherein the device may be implemented by software and/or hardware, and may generally be integrated in a central node of the blockchain system. Fig. 1 is a flowchart illustrating a transaction method for a blockchain system according to an embodiment of the present invention, as shown in fig. 1, the method includes:
s110, after a transaction request generated by a first transaction party is received, verifying transaction information carried in the transaction request and signed by a first private key of the first transaction party and a second private key of a second transaction party by adopting a first public key of the first transaction party and a second public key of the second transaction party, wherein the transaction information comprises a first transaction party account number, a second transaction party account number and a transaction amount.
In this embodiment, the first transaction part and the second transaction part may sign the transaction information in the transaction request by using their own private keys, and the transaction request may be generated by the first transaction part device and directly or indirectly sent to the local terminal by the first transaction part device. For example, the first transaction party may sign the transaction information of this time by using a first private key of the first transaction party, and send the signed transaction information to the second transaction party; the second trading party signs the trading information signed by the first trading party again by adopting a second private key of the second trading party and returns the signed trading information to the first trading party, and the first trading party generates a trading request based on the received trading information signed by the two trading parties and sends the trading request to the home terminal, so that the first trading party can directly send the trading request to a central node in the block chain system. Or the first trading party can generate a trading request, sign the trading information carried in the trading request by adopting a first private key of the first trading party, and send the trading request obtained after the trading information is signed to the second trading party; the second trading party signs the trading information which is carried in the trading request and signed by the first trading party again by adopting a second private key of the second trading party, and sends the trading request obtained after signing to the home terminal, so that the first trading party can indirectly send the trading request to a central node in the block chain system through the second trading party. The first transaction party and the second transaction party can be understood as a payer and a payee of the transaction, that is, the first transaction party is the payer of the transaction and the second transaction party is the payee of the transaction, or the first transaction party is the payee of the transaction and the first transaction party is the payer of the transaction.
In this embodiment, the transaction request may or may not include the signature sequence of the transaction information. Optionally, when the transaction request includes a signature sequence of the transaction information, the process of verifying the transaction information by the home terminal may include: acquiring a first public key of a first transaction party, a second public key of a second transaction party and a signature sequence when the first transaction party equipment and the second transaction party equipment adopt corresponding private keys to sign the transaction information according to the transaction request; according to the reverse order of the signature order, decrypting the transaction request by adopting the first public key and the second public key to obtain transaction information of the transaction request; if the transaction information is successfully acquired, the transaction request is judged to pass the verification, and correspondingly, if the transaction information is unsuccessfully acquired, the transaction request can be judged to fail the verification. Taking the transaction request as a payment request, the first transaction party as a payer, the second transaction party as a payee, the payer equipment finishes signing the transaction information, and the payee equipment signs the transaction information signed by the payer again as an example, after receiving the transaction request, the home terminal can firstly decrypt the transaction information signed by the second public key of the payee according to the reverse order of the signing order to obtain the transaction information signed by the payer; the obtained transaction information signed by the payer is then decrypted again using the first public key of the payer to obtain unsigned transaction information. The first public key and the second public key may be obtained in a transaction request, a local system or a blockchain system, and accordingly, the transaction request may or may not include the first public key and the second public key, which is not limited herein.
And S120, if the verification is passed, modifying a first account balance of the first transaction party account number and a second account balance of the second transaction party account number, which are stored in the local terminal, based on the transaction amount.
Correspondingly, if the verification is not passed, the first transaction part can be informed of the transaction failure through the first transaction part device and/or the second transaction part can be informed of the transaction failure through the second transaction part device, and the operation is finished.
In this embodiment, the transaction request received by the local terminal may include a payment request and/or a payment receipt request. If the technical scheme only supports a scene for the payment of the payee by the payment party (namely when the transaction request is a payment request), the account balance in the account number (namely, the account number of the payer) of the first transaction party can be reduced by corresponding transaction amount, and the account balance in the account number (namely, the account number of the payee) of the second transaction party can be increased by corresponding transaction amount; if the technical scheme is only used in a scene that a payer receives money from a payee (namely, when the transaction request is a money receiving request), the account balance in the account number of the first transaction party (namely, the account number of the payee) can be increased by a corresponding transaction amount, and the account balance in the account number of the second transaction party (namely, the account number of the payer) can be increased by a corresponding transaction amount; if the technical scheme is applied to a scene that the payer carries out payment to the payee and a scene that the payee carries out collection to the payer, after the transaction request is received, the type of the transaction request (payment request or collection request) can be determined firstly, and then the account balance of the first transaction party and the second transaction party is modified based on the method.
S130, sending a transaction confirmation request to second transaction side equipment, and receiving a transaction confirmation instruction returned by the second transaction equipment based on the transaction confirmation request to complete the transaction.
In this embodiment, since the transaction request is generated by the first transaction party, after the another party (i.e. the second transaction party) of the transaction confirms the transaction, it can be regarded that the online transaction process of the transaction is completed. For example, the local terminal may send a transaction confirmation request including transaction information of the transaction to the second transaction party device; after receiving the transaction confirmation request sent by the home terminal, the second transaction party equipment can generate a transaction confirmation instruction based on the confirmation operation of the second transaction party, sign the transaction information contained in the transaction confirmation instruction by adopting a second private key of the second transaction party equipment, and send the transaction confirmation instruction carrying the signed transaction information to the home terminal; correspondingly, after receiving the transaction confirmation information, the home terminal can decrypt the signed transaction information by using the second public key of the second transaction party to verify the identity of the second transaction party, if the verification is successful (namely the decryption is successful), the transaction is completed, and if the verification is failed (namely the decryption is failed), the balance of the first account of the first transaction party and the balance of the second account of the second transaction party can be restored to cancel the transaction, and the first transaction party and/or the second transaction party are/is notified that the transaction is failed.
According to the transaction method, the transaction device, the central node and the transaction system for the blockchain system, after a transaction request is received, a first public key of a first transaction party and a second public key of a second transaction party are adopted to verify transaction information carried in the transaction request, if the verification is passed, account balances of an account number of the first transaction party and an account number of the second transaction party are modified based on a transaction amount in the transaction information, a transaction confirmation request is sent to second transaction party equipment, and a transaction confirmation instruction returned by the second transaction party equipment based on the transaction confirmation request is received, so that the transaction is completed. By adopting the technical scheme, the resource occupation of the block chain system by the quick payment function can be reduced, the payment speed among different users in the block chain system is improved, and the whole monitoring of the payment currency value flow in the block chain system is realized.
Example two
Fig. 2 is a flowchart illustrating a transaction method for a blockchain system according to a second embodiment of the present invention. The embodiment is optimized on the basis of the above embodiment, and further, the transaction method for the blockchain system provided by the embodiment may further include: adding the transaction information, the first account balance and the second account balance as transaction records of the transaction to a local to-be-uplink transaction list; and when the current condition meets the preset writing condition, writing each transaction record in the transaction list to be linked into a block chain of the block chain system, and deleting each transaction record after the writing is successful.
Further, before the modifying the locally stored first account balance of the first transaction part account number and the second account balance of the second transaction part account number based on the transaction amount, the method further includes: and determining that an account information list of the local terminal comprises the first transaction party account and the second transaction party account, and the account balance of a payer of the transaction is greater than or equal to the transaction amount, wherein the payer is one of the first transaction party and the second transaction party for payment.
Correspondingly, as shown in fig. 2, the transaction method for the blockchain system provided by the embodiment includes:
s210, after receiving a transaction request generated by a first transaction party, verifying transaction information carried in the transaction request and signed by a first private key of the first transaction party and a second private key of a second transaction party by using a first public key of the first transaction party and a second public key of the second transaction party, wherein the transaction information comprises a first transaction party account number, a second transaction party account number and a transaction amount.
And S220, if the verification is passed, determining that the account information list of the local terminal comprises the first transaction party account and the second transaction party account, and the account balance of a payer of the transaction is more than or equal to the transaction amount, wherein the payer is one of the first transaction party and the second transaction party for payment.
In this embodiment, in order to ensure that transactions between different users can be performed smoothly, two parties performing the transactions need to have account numbers in the central node of the blockchain system, and the account balance of the account numbers of the payers in the first transaction party and the second transaction party is greater than the local transaction amount. Correspondingly, if the account information list of the home terminal does not include the first transaction party account and/or the second transaction party account, or the account balance of the first transaction party and the second transaction party payment party is less than the transaction amount, the first transaction party and/or the second transaction party can be notified that the transaction is failed and the operation is ended. Wherein the payer may be a first transaction party or a second transaction party.
In this embodiment, one or more blockchains may be included in the blockchain system. When a blockchain is included in the blockchain system, the account number of a certain transaction party (i.e. a certain user in the blockchain system) in the central node may be the same as the account number of the certain transaction party in the blockchain of the blockchain system, and the account balance of the certain transaction party in the central node is preferably the account balance of the certain transaction party in the blockchain, so that the consistency of the account numbers of the same user in the blockchain system is increased, and the calculation amount required for writing transaction information into the blockchain is reduced. The account number of a certain transaction party in the blockchain system can be set in a random determination mode, a blockchain system allocation mode or a user self-setting mode when the certain transaction party joins the blockchain system; the transaction party can transfer coins in other accounts of the user into the account of the user in the blockchain system through a recharging request sent to the blockchain, so that the account number of the user in the blockchain is recharged, and after recharging, the home terminal can modify the account balance of the account number stored in the home terminal based on the account balance of the account number in the blockchain.
When the blockchain system comprises a plurality of blockchains, taking the example that the blockchain system comprises a main transaction blockchain and a small transaction blockchain for recording small transaction data, and a central node is used for assisting the small transaction blockchain to perform small transaction, the account number of a certain transaction party in the main transaction blockchain can be set in the modes of random determination, distribution by the blockchain system or self setting by a user when the certain transaction party is added into the blockchain system; the account number of the transaction party in the minor transaction blockchain is preferably the same as the account number of the transaction party in the main transaction blockchain, so that the account number consistency of the same user in the blockchain system is improved. In this case, when an account needs to be opened in the minor transaction blockchain, the transaction party may send an account opening application carrying identity information of the transaction party to a central node in the system through a transaction party device to open an account, and accordingly, after receiving an account opening request sent by the transaction party device, the central node may obtain account information of the transaction party logging in the transaction party device in a main transaction blockchain of the blockchain system based on the identity information carried in the account opening request, where the transaction party includes the first transaction party and/or the second transaction party; and adding the account information into an account information list of the local terminal and a small transaction block chain of a block chain system.
After the transaction party opens an account or when the account balance is less than the transaction amount, a recharging request can be sent to the central node through the logged transaction party equipment for recharging. Correspondingly, after receiving the recharge request sent by the transaction party device, the central node may send a transaction application to the bank card account number, the pay bank account number, the wechat account number and/or the main blockchain account number of the transaction party carried in the recharge request, so as to transfer the corresponding amount of money from the corresponding account to the small-amount transaction blockchain, which is not limited herein. To further improve the security and manageability of transaction information in the blockchain system, it is preferable that the accounts in the minor transaction blockchain can be recharged by the transaction party's account in the main transaction blockchain. At this time, after receiving a recharging request carrying recharging information sent by a transaction party device, a central node may send a chain sending application to a main transaction block chain and a small-amount transaction block chain of a block chain system, so as to write the recharging information into the main transaction block chain and the small-amount transaction block chain, wherein the recharging information includes a transaction party account and a recharging amount; and after the recharging information is successfully written, acquiring balance information of the transaction party account in the small-amount transaction block chain after recharging, and updating the account balance of the transaction party account stored in the local terminal based on the balance information.
Here, it should be noted that the scheme of this embodiment may be used in a small amount transaction scenario or any non-small amount transaction scenario, and when the scheme is applied in a small amount transaction scenario, before the modifying the first account balance of the first transaction party account and the second account balance of the second transaction party account stored in the local terminal based on the transaction amount, the method may further include: and determining that the transaction amount is less than or equal to a transaction amount threshold value of the small amount transaction of the blockchain system, and correspondingly, if the transaction amount is greater than the transaction amount threshold value, informing the first transaction party and/or the second transaction party that the transaction fails and ending the operation. In addition, in the technical scheme, after a recharging request for recharging the account in the small transaction blockchain sent by the transaction party is received, whether the account of the transaction party in the small transaction blockchain (or the home terminal) exists or not can be judged firstly, and if yes, the account of the transaction party in the small transaction blockchain is recharged based on the recharging request; correspondingly, if the transaction part does not exist, the operation can be finished by the failure of recharging by the transaction part, or the transaction part can automatically open an account in the small-amount transaction block chain for the transaction part based on the account of the transaction part in the main transaction block chain and recharge based on the recharging request after the opening of the account is finished, so that the time consumed by the transaction part for respectively sending the opening request and the recharging request is reduced.
S230, modifying a first account balance of the first transaction party account number and a second account balance of the second transaction party account number which are stored in the local terminal based on the transaction amount.
S240, a transaction confirmation request is sent to the second transaction side device, and a transaction confirmation instruction returned by the second transaction device based on the transaction confirmation request is received, so that the transaction is completed.
And S250, adding the transaction information, the first account balance and the second account balance as transaction records of the transaction to a local to-be-uplink transaction list.
And S260, when the current condition meets the preset writing condition, writing each transaction record in the to-be-linked transaction list into a block chain of the block chain system, and deleting each transaction record after the writing is successful.
In this embodiment, after receiving a transaction confirmation instruction returned by the second transaction device, the transaction record including the transaction information of the current transaction, the first account balance, and the second account balance may be written into the blockchain of the blockchain system. The writing time can be set as required, for example, a chain sending application can be sent to the blockchain of the blockchain system after a transaction confirmation instruction returned by the second transaction device is received, so as to write the transaction record of the transaction into the blockchain of the blockchain system; or storing the transaction record locally, writing the locally stored transaction record into the block chain of the block chain system when the current condition meets the preset writing condition, and deleting the transaction record successfully written into the block chain. The preset writing condition may be that the storage space (or amount) occupied by the locally stored transaction record reaches a preset space threshold (or amount threshold), or the current time reaches the preset writing time of the transaction record, and the like, which is not limited herein. Here, the space threshold may be set to a size of 1M or 2M, the number threshold may be set to a value of 1000, 2000, or the like, and the writing time may be set to be written once every time length of 1 minute, 2 minutes, or 5 minutes or the like. Here, it should be noted that, when the blockchain system includes the minor trading blockchain and the main trading blockchain and the technical solution is applied to a minor trading scenario, each trading record in the to-be-uplink trading list may be preferably written into the minor trading blockchain of the blockchain system.
In the transaction method for the blockchain system provided in the second embodiment of the present invention, after receiving a transaction request generated by a first transaction party, the public keys of both transaction parties are respectively used to verify transaction information, if the verification is successful, and it is further determined that the account information list of the home terminal includes account numbers of both transaction parties and the account balance of a payer is greater than or equal to the transaction amount of this time, the account balance of both transaction parties is modified based on the transaction amount, a transaction confirmation request is sent to a second transaction party device, and a transaction confirmation instruction returned by the second transaction device is received, the transaction record of this time is added to a local to-be-linked transaction list, and when the current condition meets a preset writing condition, each transaction record in the to-be-linked transaction list is written into a blockchain of the blockchain system. By adopting the technical scheme, the resource occupation of the block chain system by the quick payment function can be reduced, the payment speed among different users in the block chain system is improved, and the whole monitoring of the payment currency value flow in the block chain system is realized; and the safety and the openness of funds in the blockchain system can be improved, and the use experience of a user is improved.
On the basis of the foregoing embodiment, the transaction method for the blockchain system provided in this embodiment may further include: and if a transaction cancellation instruction sent by the second transaction side equipment is received or a transaction confirmation instruction returned by the second transaction side equipment is not received within a set time length after the transaction confirmation request is sent, restoring the first account balance and the second account balance based on the transaction amount to cancel the transaction, so that the flexibility of the transaction is improved, and the timeliness of fund flow in the account balance of each transaction side is improved. The set time length can be set according to needs, and is not limited herein. Here, it should be noted that, if the local end receives a transaction revocation instruction sent by the second transaction party device, and the transaction information of the current transaction is written in the blockchain of the transaction system, the operation of restoring the first account balance and the second account balance may not be executed, and the second transaction party is notified that the transaction revocation is failed.
