The operational order that mobile terminal remote is sent, the including but not limited at least one such as 3/4/5G components, network interface card.
Step a：The control device refuses the user and accesses corresponding home equipment, and creates new block, by user
Operational order and denied access behavior be written in new block；
Step b：New block publication is stored on its block chain main chain and is synchronized by the control device is stored into the block
On the control device of other nodes of chain database.
Step 5：The control device distributes private key according to intelligent contract to user；
Step 6：The control device creates new block, the operational order of user is written in new block, and according to intelligence
Energy contract tests to operational order, if lawful acts, then controls home equipment connected to it and executes corresponding function；
In the step 6, legitimacy certification include but not limited to recognition of face certification, fingerprint recognition certification, iris recognition certification and
At least one of Application on Voiceprint Recognition certification.
In the step 6, if legitimacy certification be illegal act or by invasion destroy, the control device not to its
The home equipment of connection sends out corresponding control instruction.
Step 7：The control device new block publication is stored on its block chain main chain and synchronize be stored into it is described
On the control device of other nodes of block chain database.
Preferably, in above-mentioned step 6, if legitimacy certification is illegal act or is destroyed by invasion, in the step 7
In, new block publication is not stored on its block chain main chain by the control device, and automatically disengages the block chain number
According to library.
The control device will be unable to access the block chain database after being detached from the block chain database, create
Any block built, which can not also synchronize, to be stored on other nodes of the block chain database, and the control device only exists
The block chain database could be accessed again after repairing resetting.
As shown in figure 4, each block in block chain main chain includes block head and block body two parts, in block head
Data include but not limited to the timestamp for having the block to create, the hash value of the hash value and a upper block of local area block（Create generation
Except block）Deng can also include Merkel's root according to different application scene（Merkle Tree）, random number etc.；Block body
In data other than above-mentioned operational order and account information, can also include each household according to different application scene
The operating parameter of equipment, collected audio, video data etc..Wherein, the data in the block body of wound generation block are in addition to intelligent contract
Except, further include the data that block chain main chain is started and safeguarded according to intelligent contract.
The hash value is to calculate the identical characteristic value of a length to arbitrary content using hash algorithm, block chain
Hash length is 256, and no matter initial data no matter which kind of is, can all calculate the binary digit of only one 256, and
And can ensure, as long as original contents are different, corresponding hash value is centainly different.Therefore, the number in the block body of either block
It according to being changed, is bound to that the hash value of the block body is caused to change, then influences note in the block body of next block
The upper block hash value of record also changes, and thus causes chain reaction so that the data in block chain main chain are once written
It can not just change, is irrevocable.
