Description
Technical Field
The invention relates to the technical field of block chains, in particular to a commodity transaction method and system based on a block chain.
Background
Block chaining, as a distributed ledger technique, is currently widely used in various computer systems as a bottom layer technique. In the e-commerce service, due to the limited performance of the blockchain, the commodity transaction service based on the blockchain is a big problem currently. In a blockchain, validation of a transaction requires consensus to be completed by most of the nodes in the blockchain before it can be considered valid. However, as the service real-time performance requirement of the e-commerce is higher, if time periods of double 11 and double 12 occur, the service concurrency is extremely high, most systems constructed by the block chain bottom layer are limited by performance, and the performance of recording transactions in real time by using the block chain cannot be achieved.
According to the invention, the form of the merchant own block chain is constructed outside the main transaction block chain, so that the batch processing of the main transaction block chain transaction is realized, and the problem that batch transaction cannot be carried out on the chain is solved. Meanwhile, the security of the on-chain transaction is ensured by setting an on-chain transaction auditing mechanism, and the fairness of the on-chain transaction is ensured by setting a deposit intelligent contract and a merchant chain admission mechanism.
Patent document CN110889730A (application number: 201810927235.3) discloses a commodity transaction method based on a block chain, which belongs to the field of commodity transaction, and a seller uploads commodity information to a block chain transaction subsystem through a buyer client. And the commodity display platform acquires the commodity information of the commodity transaction subsystem from the blockchain transaction subsystem and displays the commodity information. The buyer inputs commodity information through the buyer platform to search or selects required products through browsing the commodity display platform. The buyer communicates commodity transaction information with the buyer through the block chain subsystem through the buyer platform. Both parties determine to buy and sell, and the block chain transaction system transmits the commodity transaction information to the commodity display platform. The commodity display platform stores commodity transaction information and transmits order information to the identification code generation subsystem. The identification code generation subsystem generates an identification code and transmits the identification code to the seller platform; the seller prints the identification code, labels and identification codes for delivery. And the user receives goods and identifies the identification code through the commodity identification code identification subsystem.

Example 2
Example 2 is a preferred example of example 1
The invention provides a commodity transaction method based on a block chain, which comprises the following steps:
the method comprises the following steps: firstly, a commodity transaction main blockchain is deployed and used for recording transaction records of commodities, and the blockchain is a distributively operated blockchain.
Step two: if the shopping mall owns the resident merchant, a merchant owned block chain is established for the merchant, and the merchant block chain is operated by the merchant.
Step three: the cooperation mechanism of the merchant block chain and the main block chain is as follows: when a block chain of the merchant needs to be constructed and trade is carried out, a deposit needs to be paid in advance in the intelligent contract of the merchant deposit on the block chain of the merchant. When a block is generated by the business block chain, the synchronization must be carried out on the main block chain, and the block is confirmed after the confirmation of the main block chain.
Step four: each merchant blockchain is relatively independent and cannot interact across chains. The purchasing behavior of the user at the merchant can be directly recorded in the merchant block chain.
Step five: based on the steps 1-4, the workload of the main block chain can be changed from that each transaction needs to be confirmed to that the workload of one block transaction of the merchant block chain is confirmed once, so that the transaction efficiency is greatly improved, and the transaction capacity is expanded.
Step six: how to guarantee the safety and fairness of transactions within one commodity block chain: funds for the transaction need to be withdrawn after a challenge period (e.g., 7 days) during which time relevant users participating in the transaction submit review instructions to the blockchain deposit contract to trigger review if someone proposes fairness for the merchant blockchain.
Step seven: the audit is processed according to the transaction order of the merchant blockchain, from oldest transaction to newest transaction one by one.
For example: user a bought 5 sugar in 10 yuan, user b bought 10 sugar in 20 yuan, and the merchant stealed 500 sugar to user c. At the moment, the fairness of the merchant block chain is questioned, transaction review is started, 5 sugars of the user a are firstly settled, 10 sugars of the user b are then settled, and finally, less than 500 sugars remain, the merchant is considered to cheat, and the intelligent contract automatically penalizes the pre-paid deposit of the merchant.
The merchant chain is used for executing all transaction behaviors of a single merchant, and comprises the steps of constructing accounts corresponding to the main chain one by one, synchronizing commodity information, recording transaction information and synchronizing the transaction information to the main chain. Meanwhile, if the merchant needs additional intelligent contracts, the intelligent contracts also need to be built in the merchant chain.
The business chain needs to synchronously pack transaction information to the main chain in a fixed stage; the deposit intelligent contract corresponding to the merchant chain is responsible for executing transaction examination and triggering of merchant chain transaction
