4 is a diagram illustrating a system for verifying the integrity of transactions performed on a block-chain basis in accordance with one embodiment.

Referring to FIG. 4, the system includes a local server 100, a transaction target terminal 1, and a main server 1000.

In one embodiment, the local server 100 performs a transaction with a predetermined transaction target terminal 1, and the transaction can be performed based on a smart contract in a block chain.

In this specification, a smart contract means that a transaction is performed according to a pre-stored condition in a block chain. For example, it may mean that a transaction is automatically performed when a transaction request satisfying a pre-stored condition is acquired. Also, transactions that are performed automatically are performed according to the conditions pre-stored in the block chain.

For example, the transaction target terminal 1 may refer to a virtual money management module provided at the above-mentioned merchant. When the cash settlement request for the virtual currency is obtained from the transaction target terminal 1, the above-described block chain holding servers or the local server 100 can automatically perform the cash settlement transaction according to the previously stored smart contract condition.

For example, the condition of the smart contract is that when a cash payment request for the virtual money is received from the pre-stored (or authenticated) transaction target terminal 1, the integrity of the corresponding virtual money is verified, The local server 100 automatically generates the exchange information based on the exchange rate information obtained in accordance with the exchange rate information, stores the generated exchange information in the block chain, and transmits the exchange information to the local server 100, And performing the remittance to the user 1, but the present invention is not limited thereto.

Likewise, the process of paying employees the virtual currency generated based on employee performance information can also be performed based on the smart contract.

For example, when the transaction target terminal 1 is the terminal that calculates the performance of the employee terminal 200 or the employee, the transaction target terminal 1 performs the virtual money payment request based on the employee performance information, The holding servers or the local server 100 can automatically pay the virtual money according to the previously stored smart contract condition.

Likewise, when the performance information uploaded from the transaction target terminal 1 satisfies a predetermined condition, information for providing the virtual currency corresponding to the performance information may be stored in the block chain as the smart contract information.

Therefore, the transaction target terminal 1 uploads the virtual money payment request including the performance information, automatically calculates the virtual money payment amount based on the predetermined condition based on the corresponding smart contract, .

In one embodiment, the local server 100 may request the main server 1000 to verify the integrity of such transactions.

The main server 1000 can verify the integrity of transactions performed by the local server 100 at the request of the local server 100. [

In one embodiment, the main server 1000 may obtain transaction information corresponding to a request from the local server. In addition, the main server 1000 can acquire information on the smart contract corresponding to the request of the local server 100.

The main server 1000 compares the transaction conditions of the smart contract with the transaction information performed by the local server 100 and can verify the integrity of transactions performed by the local server 100 based on the comparison result.

For example, when the main server 1000 acquires the transaction condition of the smart contract and substitutes the transaction information performed by the local server 100 into the transaction condition of the smart contract, Whether or not they match.

If the result of substituting the transaction information performed by the local server 100 and the transaction condition of the smart contract is different from the transaction information performed by the local server 100, the local server 100 determines that there is a problem with the transaction .

In one embodiment, the main server 1000 may verify the integrity of the transaction terms of the smart contract.

For example, the main server 1000 may acquire a predetermined simulation transaction information database.

The main server 1000 can substitute the transaction information based on the simulation transaction information database into the transaction condition of the smart contract and compare the assignment result with the database result.

In one embodiment, when the result of substituting the result stored in the database and the simulation transaction information into the transaction condition of the smart contract is different from the predetermined reference value or more, the main server 1000 judges that there is a problem with the transaction condition of the smart contract can do.

In one embodiment, the local server 100 may request the main server 1000 to verify the integrity of the transaction information performed based on the smart contract and the smart contract used in the system according to the disclosed embodiment.

The main server 1000 may perform integrity verification based on the request, and may transmit the execution result to the local server 100.

The local server 100 may suspend transactions based on the smart contract if it obtains information that there is a problem with the smart contract or transaction information.

According to the disclosed embodiment, there is an advantage that the convenience of the smart contract can be added to safety by verifying the integrity of a transaction performed based on the block chain.
