There is disclosed a blockchain-based system, and an electronic apparatus and a method in the system. The electronic apparatus at a control node end includes a processor configured to: verify, in response to an ownership declaration for a new object that is first introduced from a to-be-verified node in the system, the ownership declaration; and sign, in a case that the verification is successful, the ownership declaration to be returned to the to-be-verified node, so that the signed ownership declaration is verified by other nodes in the system and a record regarding the ownership declaration is added to the blockchain. According to the embodiment of the disclosure, it is possible to verify the newly introduced object in the blockchain-based system without binding with a cipher coin, while maintaining a peer-to-peer architecture of the blockchain-based system.
