Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. The embodiments of the present invention, and all other embodiments that can be obtained by those skilled in the art without any inventive work, belong to the protection scope of the present invention.
A specific blockchain transaction recording method, apparatus, blockchain node, and computer medium provided in the embodiments of the present application are described below with reference to the accompanying drawings.
As shown in fig. 1, a method for recording a blockchain transaction provided in an embodiment of the present application includes:
s101, a buyer and a seller create a transaction template, and a corresponding transaction rule is formulated according to the transaction template;
s102, the block chain of the tree structure receives the transaction rule and carries out transaction according to the transaction rule;
and S103, recording the transaction data in a database after the transaction is finished.
The working principle of the blockchain transaction recording method is as follows: the buyer and the seller create a trading template, and a corresponding trading rule is formulated according to the trading module; the block chain of the tree structure receives the transaction rule and carries out transaction according to the transaction rule; and recording the transaction data in a database after the transaction is finished.
The tree-shaped structure block chain is also called a tree-shaped block chain, the tree-shaped structure block chain is a multi-tree-shaped block structure with branches as branches and leaves which are continuously generated in a branching mode by taking a main chain as a root, the tree-shaped structure is a main chain and multi-application branch chain, and the problem of transaction expansibility and high concurrency which cannot be solved by a single-chain structure is solved by infinite expansion of the branch chains. The arrangement blocks are stored by adopting a tree structure, and can be forked according to the service type and the data load to form a plurality of branches. The blocks between branches are independent, and the newly added block is only related to the data of the branch. In the case of multiple forking, it can be distributed into multiple forking blocks according to the traffic data traffic, and the resulting scalability and high concurrency are the basic performances required by the IoT system. The multi-branch structure of the tree block chain is composed of a unique safe main chain and a plurality of application branch chains, wherein the safe main chain is used for supporting a whole network consensus mechanism, and the application branch chains are used for actual services. The application branch can provide low-delay transaction confirmation of 2 seconds at least, and the user can specify the transaction urgency and pay the corresponding transaction commission, thereby realizing the low-delay service.
In some embodiments, as shown in fig. 2, the creating a transaction template by the buyer and the seller, and formulating the corresponding transaction rule according to the transaction module includes:
s201, creating a cross-chain trading template; the cross-chain transaction template comprises transaction template addresses generated by wallet addresses of buyers and sellers, buyer branched chains and seller branched chains and block heights locked on the respective branched chains, wherein the transaction template addresses are used for receiving Token transferred by any user;
s202, when the Token is transferred out of the transaction template address, if the block height is within the locking height, signing the transaction template address to obtain signature data;
s203, the two transaction parties verify whether the signature data is correct through a public key provided by the other party, and whether the signature data is a signature of a corresponding cross-link transaction template is confirmed;
and S204, transferring out the Token in the cross-chain transaction template through the signature data provided by the opposite party and the signature data of the opposite party.
The cross-chain transaction in this embodiment may enable a synchronous value exchange between blockchain branches without trust. In practical application, services can be divided according to relevant factors such as service flow, equipment type, space region and the like, and the divided services are dispersed into a plurality of branches. Frequently interacting devices usually hold the same Token branch and perform data transaction in the same Token branch. But the need to interact with other devices holding the Token as a business entity also exists objectively. In this case, the Token exchange between branches can be realized by cross-chain transaction. On one hand, cross-chain transaction can be completed under the condition of no trust, and fairness to both sides is ensured by utilizing the technical principle; on the other hand, cross-chain transaction synchronously enters a block between two branched chains, so that high efficiency and effectiveness are guaranteed. This provides good underlying technical support for applications including decentralized exchanges, Token redemption gateways, etc.
Specifically, the trade rules of the cross-chain trade template are as follows: 1) and creating a transaction template, wherein the transaction template comprises the addresses of the wallets of the two parties and the hash of the two branch chains participating in the transaction, and the block heights locked on the respective branch chains, generating a template address of the transaction by using the data, and if any value of the data is changed, changing the template address. The address can be used for receiving Token entered by any user, but within the locking height, signature data of both parties is needed to complete the process of transferring out Token under the template address. After the lock block is high, the parties involved in the transaction can turn away Token on the branch where they are located. And signing the cross-connection transaction template address to obtain signature data. The two transaction parties can verify whether the signature data is correct through a public key provided by the other party and confirm whether the signature data is a signature of a corresponding cross-chain transaction template. The user with the low locking block is required to send the signature result of the user to the other side. The Token in the cross-linked transaction template can be transferred away through the signature data provided by the other party and the signature data of the user, and the wallet of the user needs to be in an open state at the moment.
In some embodiments, as shown in fig. 3, the creating a transaction template by the buyer and the seller, and formulating the corresponding transaction rule according to the transaction module includes:
s301, establishing an e-commerce payment transaction template; the E-commerce payment transaction template generates a transaction certificate through transaction information, commodity information and express delivery information of a buyer and a seller, and when the transaction certificate exceeds the validity period, a data provider needs to update the transaction certificate; if the transaction is interrupted or ended, the data provider extracts consumption Token from the corresponding order transaction on the branched chain with the final signature certification;
s302, transaction is carried out in a block chain, a buyer in a locking block height sends signature data to a seller, or a Token is transferred to a fund pool, and the seller can freely withdraw money after the locking block height;
s303, if the buyer refuses to pay, transferring the Token of the transaction fee into a fund pool; the transaction fee includes: a transaction amount and a security amount, the security amount being used in a security payment scenario.
Specifically, the transaction rule of the e-commerce payment transaction template is that a transaction certificate is generated through transaction information, commodity information and express delivery information of a buyer and a seller, and a data provider needs to update the transaction certificate whenever the transaction certificate exceeds the validity period. Supposing that the two parties agree to use t as a data settlement period, and after t intervals, the data demand party sends back to the other party by using a signature certificate as a confirmation reply; whenever the transaction is interrupted or ended, the data provider extracts the consumption Token from the chain corresponding to the order transaction with the last signature proof. When the data provider first extracts Token from the order transaction, the demander can then retrieve the remaining Token immediately. If the provider does not transfer the corresponding Token, the requester may also retrieve the Token with a transaction containing a valid proof of transaction that will be broadcast but locked by the packaging node by 3 block height. If no valid transaction identification is included, the block height is locked 2880 from the block where the order was traded. During the locking period, if the data provider has a dispute, the data provider can send the valid transaction of the data provider to preferentially retrieve Token, and the disputed transaction can be discarded.
The transaction flow is that the seller sells the commodity, the buyer buys the commodity, goes to the centralized point-to-point transaction, and the transaction Token for which the buyer refuses to pay enters the fund pool. The transaction fee comprises a transaction amount and a safety amount, the transaction amount and the safety amount can be defined by users, and the safety amount is used in a safety payment scene and is used for dealing with the situation that a seller does not deliver goods after receiving the Token or the buyer maliciously transfers the Token into a fund pool.
Three situations may occur during the transaction: the transaction is normally completed, the buyer is not confirmed after the block height is reached, and the buyer is not satisfied.
When the transaction is completed normally, the buyer is satisfied with the goods, and the confirmation information (signature data) is transmitted to the seller, and the seller performs a withdrawal operation using the signature information.
When the buyer does not confirm the arrival locking speed, the seller does not need to obtain the buyer signature data and cash up directly.
When the buyer is not satisfied, the buyer may transfer Token to the fund pool and the seller may not receive Token.
However, if the buyer intentionally transfers Token into the fund pool, a third party "arbitrating" party may initiate an arbitration template to decide the winner and loser by node voting, and a certain proportion of Token is rewarded to the voter and initiator while Token is transferred to the winner.
Wherein the seller provides the goods, the buyer provides the goods, and the arbitrator initiates the arbitration by any node within the fund allowance withdrawal height.
In some embodiments, the transaction template is provided with a secure payment scenario;
and if the Token can not be transferred from the transaction template address after the transaction is sent out, the third party helps to transfer the Token and obtain the reward of the third party through the transaction template address and the signature data.
Specifically, if one party sends out the transaction and does not turn Token in the "priority packaging height of the trader", then a third party intervenes in the packaging process, and the third party can be a common node or a super node, and can help packaging and obtain a third party packaging reward through the From and To addresses and signature data in the template. The cross-chain trading template is a disposable template, and the code is further upgraded and can be modified into a reusable cross-chain trading template.
For example, both the buyer and seller mortgage the same amount of Token to ensure that the transaction is approximately terminated properly. For example, the price of a commodity S is 100Big, the seller can set the security amount of the mortgage to 10Big, after the template is created, the seller needs to send out the commodity and pay the mortgage of 10Big, at this time, the buyer needs to pay 110Big to purchase the commodity S, after the transaction is finished, the buyer obtains the commodity S and 10Big, and the seller obtains 110 Big.
Preferably, the cross-chain trading template is a one-time trading template. If the code is further upgraded, the code can be modified into a reusable cross-linked transaction template.
Preferably, when Token in the cross-chain transaction template is transferred out to the wallet address, the wallet of the user is required to be in an open state.
