A system for registering an asset of which owner cannot be specified or ownership does not exist, in a blockchain by splitting the asset into a share and creating a land registration map and address of the share, the system comprises a blockchain node with a processor configured to:
- split the asset into a plurality of unit-shares according to a predetermined splitting rule;
- create the land registration map for each of the plurality of split unit-shares in the form of a cell with a specific shape on a map or a model for the asset;
- and
- create an address by assigning a unique identifier to each of the plurality of split unit-shares,
- wherein the asset is the one of which owner cannot be specified or ownership does not exist, and the created unit-share, the land registration map, and the address are respectively the unit-share-on-the-blockchain, the land registration map-on-the-blockchain, and the address-on-the-blockchain, and
- wherein the system is configured to:
- record the unit-share-on-the-blockchain, the land-registration-map-on-the-blockchain, and the address-on-the-blockchain in the blockchain, and thereby granting public confidence to each of the registered unit-shares by shareholders-on-the-blockchain previously participating in the blockchain.
