Description

A kind of internet of things equipment autonomy interconnected method based on block chain
Technical field
The present invention relates to block chain technology, intelligent contract technology and internet of things field, specifically one kind to be based on The internet of things equipment autonomy interconnected method of block chain.
Background technology
Block chain technology, also known as distributed account book technology, it is that one kind goes center trustization, collective to safeguard distributed account book Technical scheme, its essence is to realize data not by way of storing in many ways, calculate in many ways by multiple node group participations It can distort, the believable distributed data base system of result of calculation.Block chain is not a kind of single technology, but multiple technologies The result of fusion, recorded using one account book that is reliable, being difficult to tamper with of block chain technical maintenance, the wind of trust can be reduced Danger, and the maintenance cost of many participant cooperations can be effectively reduced.The development of block chain technology makes it possible intelligent contract, Its essence is one section of code performed automatically according to the rights and duties of signature contract by a computer or computer network, The execution of contract is controlled without Centroid.Because intelligent contract uses the mode of code, contract terms are ensure that Enforce；Intelligent contract is combined with block chain so that the clause of contract can usurp once setting with regard to no third party Change.This subversive technology of intelligent contract is the key property of block chain, it will produces great change to human society structure.
In recent years, technology of Internet of things is quickly grown, the fourth industrial revolution that what it was triggered be not only, including to agricultural, The basic industry situation of the human societies such as industry, service trade, can all exert far reaching influence, so as to the production and life to whole human society Mode brings revolution.Internet of Things industry forms phase, then industry comprehensive maturity period till now, Internet of Things from the Applied D emonstration phase to standard Network technology has risen to a kind of New Economy form of economic form from simple technology.The progress of technology of Internet of things, scale are promoted Forward circulation, the continuous maturation of whole industrial chain and motive objects working application will be also promoted, accelerate the full intelligence of " all things on earth interconnection " The arrival in epoch.How in the epoch of all things on earth interconnection, preferably realize that the interaction of thing thing turns into focus of attention, and the distribution of block chain Its characteristics of going center trustization of formula account book technology, the mutual trust and interaction between internet of things equipment can be met.In such case Under, how effectively to be needed badly using block chain and intelligent contract technology come the autonomous interconnection solved between internet of things equipment as one Solve the problems, such as.
