The verification node group setting algorithm may set the verification node group 240 based on the verification reliability of the verification node 220 and the verification expertise of the verification node.

First, the verification node group 240 may be divided into a master node 250 and a general node 260, and may be divided into a master node 250 and a general node 260. The master node 250 may be a node having the highest verification reliability of the first range, and the general node 260 may be a node having verification reliability of the second range, the third range, and the nth range lower than the first range. .

The final verification of whether the volunteer activity record is manipulated is performed by assigning different weights to the master node 250 and the general node 260, and may be performed by assigning different weights according to the reliability range.

In addition, the verification node group 240 may be determined based on a service activity category having expertise for each verification node in consideration of the service activity category.

Verification algorithms for the volunteer activity records of the verification node 220 may be different, and professional volunteer activity categories having verification expertise may be set for each verification node 220 according to the accuracy of the verification algorithm. For example, verification node A has verification expertise for hospital service activities, and hospital service activities may be set as a professional service category of verification node A. Verification NodeBs have verification expertise in environmental cleanup service activities, and environmental cleanup service activities can be set as a professional service activity category of verification NodeBs.

In this way, verification of volunteer activity records is performed based on the verification node group 240, and verification accuracy of volunteer activity records can be improved.

When the verification is completed, a service activity record verification transaction including at least one volunteer activity record may be generated and transmitted on a blockchain.

3 is a conceptual diagram illustrating a cross-validation method between verification nodes according to an embodiment of the present invention.

3 discloses a method for enabling cross-validation of verification results of verification node groups.

Referring to FIG. 3 , some of the volunteer activity records may be set as cross-verification targets for testing the verification result of the verification node. For example, when n volunteer activity records are generated, a volunteer activity record among the n volunteer activity records may be set as the volunteer activity record (cross-verification) 300 .

A number of service activity records (cross-validation) 300 may be overlapped and delivered to a plurality of cross-validation groups. Each of the plurality of cross-verification groups may perform verification on each of the a number of volunteer activity records (cross-verification) 300 .

Verification results for each of the a number of volunteer activity records (cross-verification) 300 of each of the plurality of cross-verification groups are compared, cross-verification is performed on the verification results, and a reliability test for the verification node may be performed.

For example, if the verification results for b volunteer activity records (cross-verification) 300 among a volunteer activity records (cross-verification) 300 are different, the b volunteer activity records (cross-verification) 300 An error verification node, which is an incorrectly determined verification node, can be extracted through additional judgment on

Verification reliability of the error verification node is adjusted, and if verification errors occur more than a threshold number of times, the corresponding error verification node may be excluded from the verification node.

4 is a conceptual diagram illustrating a method of converting volunteer activity records into NFTs on a blockchain according to an embodiment of the present invention.

In FIG. 4, NFT issuance based on volunteer activity records is initiated.

Referring to FIG. 4 , when the verification of the volunteer activity record is completed, a volunteer activity NFT based on the volunteer activity record may be created. Volunteer activity NFTs can be issued including volunteer activity records (volunteer activity target, bonus activity area, volunteer activity period, volunteer activity person, etc.). Volunteer NFTs can be delivered to the user device and stored in the wallet of the user device.

The volunteer activity NFT may include a first type volunteer activity NFT 410 and a second type volunteer activity NFT 420 .

The first type volunteer activity NFT 410 may exist only as an original NFT for the user to keep.

The second type volunteer NFT 420 is an NFT created based on the first type volunteer NFT 410 and may be an NFT created for submission by another organization. When the user requests the second type volunteer activity NFT 420 based on the first type volunteer activity NFT 410, the second type volunteer activity NFT 420 is the first type volunteer activity NFT 410 on the blockchain. It can be created and provided based on.

It can be.

The block creation time prediction device 550 sets time sensitivity (sensitivity in seconds, sensitivity in minutes, sensitivity in time) and generates blocks so that the block creation time is equal to or less than the threshold block creation time based on the learned result. . For example, when the block generation time prediction device 550 sets the time sensitivity to second-unit sensitivity, blocks can be generated with the second-unit sensitivity such that the block generation time is equal to or less than the threshold block creation time.

According to an embodiment of the present invention, the block generation time on the blockchain may be adaptively adjusted to set a service activity certification cancelable interval. Additional verification can be performed when different judgments are made on the transaction for the above-mentioned service activity record (cross-verification) in the cancelable period.

The cancelable interval may be determined in consideration of the expected block generation time predicted by the block generation time prediction device, and the cancelable interval may be adaptively changed according to the time when a bond transaction occurs and the block creation time.
