DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to better understand the present invention, it is necessary to first set forth the blockchain technology and the low power wide area internet of things technology related to the present invention.

The Blockchain (Blockchain) is a distributed database system participated by nodes, and has the characteristics of being unchangeable and unforgeable, and can also be understood as an account book system. It is an important concept of digital cryptocurrency, a copy of a blockchain of bitcoins, for example, that records every transaction of its token. With this information we can find the value that each address has at any point in the history. The block chain is composed of a string of data blocks generated by a cryptography method, each block contains the hash value of the previous block, and the block chain is formed by connecting the starting block to the current block. The block chain is a series of data blocks which are associated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, so that the validity (anti-counterfeiting) of the information is verified and the next block is generated.

In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.

The Block chain technology is a method for storing, transmitting and proving data which is decentralized and has distributed structure, and the data Block (Block) replaces the dependence of the current internet on a central server, so that all data changes or transaction items are recorded on a cloud system. The decentralized means that since distributed accounting and storage are used, centralized hardware or management mechanisms do not exist, rights and obligations of any node are equalized, and data blocks in the system are commonly maintained by nodes having a maintenance function in the entire system.

a user device 101 for providing a user interface based on a blockchain technique for a rental house source;

a service platform 102 for providing a house rental service to the user device;

a smart door lock 104 for controlling the ingress and egress of tenants;

and the blockchain server 103 is used for providing intelligent contract services for the user equipment.

The rental room can be used as a rest room and can be rented for any time. Can be arbitrarily arranged according to the requirements of landlords.

The house renter and the house renter in the embodiment of the invention can use the same user equipment, and can also use different user equipment, wherein the user equipment comprises a mobile phone, a PDA, a notebook computer, a laptop, a handwriting pad and the like.
