Real estate information management method and device based on block chain

The invention provides a real estate information management method and device based on a block chain, and the method comprises the steps: obtaining real estate information data, and determining a current time stamp; encrypting the timestamp and the real estate information data; transmitting the encrypted data to a specific node of the blockchain by using a blockchain consensus mechanism; and storing the data in the specific node in the data block through hash operation. According to the real estate information management method and device based on a block chain, the timestamps are set, the timestamps and the obtained real estate information data are encrypted, the data uploaded to the data chains are effectively prevented from being tampered, all the data on the chains have the timestamps,the whole data record can be traced back according to the timestamps, and the safety and reliability of the data can be better guaranteed. 本发明提供一种基于区块链的不动产信息管理的方法和装置，其中该方法包括：获取不动产信息数据，确定当前时间戳；将时间戳和不动产信息数据进行加密；利用区块链共识机制，将加密后的
