User registration method and system based on block chain, and electronic equipment

The embodiment of the invention provides a user registration method and system based on a block chain and electronic equipment. The method comprises the following steps: collecting user information from a front-end system; packaging and chaining the user information by using a block chain technology; distributing the user information to each block chain upper layer node; and registering each smart scene according to the user information in each block chain upper-layer node. According to the embodiment of the invention, a user unique identity verification system is constructed by using the block chain technology, the application of the user unique identity in each smart scene is realized, the verification speed of the user identity in each smart scene can be improved, the frequent operation of the user is reduced, the use threshold of the user is reduced, and great practical significance is achieved. 本公开的实施例提供一种基于区块链的用户注册方法、系统及电子设备，方法包括：从前端系统采集用户信息；利用区块链技术封装上链所述用户信息；分发所述用户信息至各区块链上层节点；根据各所述区块链上层节点中的用户信息注册各智慧场景。
