Below in conjunction with accompanying drawing, the principle of the present invention and feature are described, example is served only for explaining the present invention, and
Non- for limiting the scope of the present invention.
Embodiment one, a kind of datacycle wiring method based on block chain.With reference to Fig. 1, the present embodiment is provided
Method is described in detail.
Referring to Fig. 1, S101, before writing new data block in data block chain, judge whether to meet default following
Ring writes trigger condition.
Specifically, before writing new data in block chain data, judge that in block chain database, original data is
No meet default trigger condition, wherein said trigger condition specifically includes time triggered condition, depositing in block chain database
Storage capacity trigger condition or concrete trigger conditions.
If S102 meets described recurrent wrIting condition, the new data block of write is covered former in data block chain
Some data blocks, new data block of otherwise writing direct, original data block is not covered.
Specifically, if original data meets default trigger condition in block chain database, such as meet time triggered
Condition or capacity trigger condition or concrete trigger conditions, then when writing new data, using the side of recurrent wrIting
Method overrides the data having been written into, and destroys original data with new data cover, when covering the original data of destruction,
It is usually data remote of first cover time；If being unsatisfactory for default trigger condition, directly write in block chain database
Enter new data, original data will not be covered.
For example, existing law-enforcing recorder or other adopt the audio/video information that card equipment gathered and be generally not stored in
In block chain, so there is the later stage possibility distorted maliciously is edited by people, and it is stored in content in block chain database then
There is not the possibility being tampered.Before writing new data in the block chain database in described law-enforcing recorder, first

Stored data, time data remote can first be capped；If the described record time is not above the described Preset Time time limit,
And described data capacity is not above described default memory capacity, then new data of writing direct, original number need not be covered
According to.Specifically, for example using memory capacity as Rule of judgment, if the memory capacity of law-enforcing recorder is 16G it is assumed that every section of sound
Video is 10M, can continuously enroll 1600 sections of little screens, after 16G storage has been expired, just starts to cover from the earliest time.
For example, for credit information service, before writing new data in the block chain database to credit information service, judge area
In block chain database, whether the credit record of the user of record record of bad behavior, and record of bad behavior specifically refers to user to be occurred being in arrears with
Refund, be late for delivery, back out of the contract, repudiation of the contract, fail to carry out the situation of contract.
Specifically, if record of bad behavior does not occur, cover the new credit of write user in default circulation time interior circulation
Record, specifically, block chain database only records nearest setting time, the personal credit record of such as nearest 3 years, and marks
Know for excellent, block chain database constantly circulates the personal credit record covering 3 years.
If record of bad behavior occurs, bad credit record is persistently retained, specifically, when user starts to give back debt,
Block chain database by the lasting reservation 5 years of this section of bad credit record, after 5 years after start the cycle over covering, write user
Bad credit record is override by new credit record.Reference can also set triggering and the cycling condition of oneself as desired.
For example, for some confidential datas, only need to be shown within the specific time according to related request, arrival sets
It is necessary to destroy after the fixed time, but the interior security reliability wanting guarantee information during detention.Using block chain data
Library storage confidential data, ensure that confidential data is not tampered with.
Specifically, if the confidential data of storage does not reach described time restriction in block chain database, proceed to protect
Stay, if reaching described time restriction, new other information of writing direct will carry out to described confidential data covering destroys.
In addition, the confidential data being stored in block chain database is then stored into block chain database after can encrypting
In, it is provided only to related personnel and check.
General materials can also be saved in block chain data, and equally conserving time limit is set, during for exceeding preservation
The general materials of limit, can be circulated covering according to predetermined trigger condition.
Furthermore it is possible to the content recurrent wrIting as requested in block chain database, such as periodic cyclic write.For example
The authority of some high-grade security systems is it should periodic cleaning and re-write authorization message.Using circulating overlayable
Block chain database, can solve the problems, such as credible and safe.
The scheme that the present embodiment provides also includes, when writing new data block in described data block chain, also will be new
Data block generate hash value write hash block chain in.Specifically, if meeting described recurrent wrIting condition, in hash area
Write the new data block hash value generating the hash value covering original data block generation in block chain, otherwise write direct new
Data block generate hash value, not to original data block generation hash value cover.Specifically, using pre-defined algorithm
Data block is carried out be calculated this data block corresponding hash value.
When being downloaded to the data in described data block chain, in order to ensure the authenticity of the data downloading,
Can verify what each data block in the data downloaded generated after the data in described data block chain is downloaded
Whether hash value is identical with the hash value of corresponding data block in described hash block chain, if identical, verifies the data of download
It is not intercepted and distorts, if it is different, being then downloaded identical until verifying again.
