Abstract: The present disclosure discloses methods, systems, an electronic device, and a storage medium for confirming a property right and for transferring a property right. The present disclosure realizes the confirmation and transfer of the ownership of a property and traceback of the ownership of the property, making the process of right confirmation and implementation is more efficient and secure, and improving the user experience.

Abstract: A blockchain-based workflow node certification method includes a certification party establishing a general workflow template. The general workflow template includes a plurality of workflow nodes each having an audit attribute for indicating whether the workflow node needs to be certified. The certification party establishes a general data template based on the general workflow template, and the general data template and the general workflow template are instantiated. A current workflow node is acquired in the instantiated general workflow template, and whether the current workflow node needs to be certified-is determined, based on the audit attribute. Certification, if needed, is performed by a centralized certification party, and users can create and modify transaction processes as needed to meet the needs of changeable transactions. By combining central certification with blockchain certification deposition, the security of workflow node process implementation and the privacy of specific data are ensured.
