Abstract
A method of sharing information on the basis of anchoring and an anchoring device supporting the same and more particularly are provided. One of the methods includes, acquiring anchoring information including first field information permitted for sharing from a target transaction record recorded in a first blockchain and recording the acquired anchoring information in a second blockchain.
Claims16
A method performed by an anchoring device to share information on the basis of anchoring, the method comprising:
- acquiring anchoring information from a target transaction record recorded in a first blockchain;
- and
- recording the acquired anchoring information in a second blockchain,
- wherein the target transaction record includes a plurality of pieces of field information including first field information permitted for sharing and second field information not permitted for sharing;
- the anchoring information includes the first field information and verification information, and the anchoring information excludes the second field information;
- the verification information includes information for verifying on the first field information and the second field information;
- and
- the information for verifying the first field information and the second field information includes a root hash value of a Merkle tree configured on the basis of the plurality of pieces of field information and a non-root hash value related to the second field information in the Merkle tree.

A method performed by a computing device to share information on the basis of anchoring, the method comprising:
- retrieving an anchoring transaction record recorded in a first blockchain, the anchoring transaction record including first field information and verification information;
- and
- verifying the first field information by using the verification information,
- wherein the anchoring transaction record is generated by anchoring a target transaction record recorded in a second blockchain;
- the target transaction record includes a plurality of pieces of field information including the first field information permitted for sharing and second field information not permitted for sharing
- wherein the verification information includes information for verifying the first field information and the second field information;
- and
- the information for verifying the first field information and the second field information includes a root hash value of a Merkle tree configured on the basis of the plurality of pieces of field information and a non-root hash value related to the second field information in the Merkle tree.

- a memory including one or more instructions;
- and
- a processor configured to, by executing the one or more instructions, acquire anchoring information from a target transaction record recorded in the first blockchain, and record the acquired anchoring information in the second blockchain,
- wherein the target transaction record includes a plurality of pieces of field information including first field information permitted for sharing and second field information not permitted for sharing;
- the anchoring information includes the first field information and verification information, and the anchoring information excludes the second field information;
- and
- the verification information includes information for verifying on the first field information and the second field information;
- and
- the verification information includes a root hash value of a Merkle tree configured on the basis of the plurality of pieces of field information and a non-root hash value related to the second field information in the Merkle tree.
