Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
Any feature disclosed in this specification (including abstract and attached drawing) unless specifically stated can be equivalent by other
Or the alternative features with similar purpose are replaced.That is, unless specifically stated, each feature is a series of equivalent or class
Like an example in feature.
A kind of block chain data monitoring and managing method provided according to the present invention, specific method include,
Construct Chain of Custody；As shown in Figure 1, the Chain of Custody includes main chain and IPFS；
Hash calculation is carried out to the block data in the business chain of supervision, generates the first cryptographic Hash, the first of generation is breathed out
Uncommon value is saved to the text space of main chain；
When carrying out anti-tamper confirmation, Hash calculation is carried out to the block data, generates the second cryptographic Hash, by the of generation
Two cryptographic Hash are compared with first cryptographic Hash, if cryptographic Hash is different, show that the block data is tampered.
The block of main chain is made of transaction record, and transaction record includes Transaction Information and text information, and text space is to hand over
The easily memory space of record the inside storage text information.Hash calculation is carried out to the block data of institutionalized existing business chain,
The first cryptographic Hash is generated, the first cryptographic Hash of generation is saved to the text space of main chain, when needing to carry out anti-tamper confirmation,
The cryptographic Hash for calculating the block data again obtains the second cryptographic Hash, if the first cryptographic Hash is identical with the second cryptographic Hash,
Illustrate that the block data should be not tampered with, if the first cryptographic Hash and the second cryptographic Hash difference, illustrate the block
Data are tampered.The realization of the present invention program, business chain and Chain of Custody do not need to use technology of the same race, are not required between business chain yet
Technology of the same race is used, applied widely, technology relevance grade is higher.
As a kind of embodiment of the invention, the method also includes by the data strip in the block data block
Number is saved to the text space of main chain；When carrying out anti-tamper confirmation, the number of data in the block data block and guarantor are compared
Whether the number of data deposited to the text space is consistent, if it is inconsistent, showing that the block data is tampered.As this
The embodiment of invention, if cryptographic Hash and number of data have one it is inconsistent, show that the block data is tampered, as
Specific embodiment can first compare cryptographic Hash and compare number of data again, can also first compare number of data and compare cryptographic Hash again,
Or compare simultaneously respectively.
As one embodiment of the invention, the method also includes saving the block data to Chain of Custody
In IPFS.As embodiment of the present invention, the block data is saved, on the one hand within a block due to block data
When storage, original data may be lost, the block data stored here can be as the backup for the data lost；Another party
Face, if the block data is tampered, the block data in addition stored can be as the evidence distorted.As the present invention
Embodiment, the block data is saved into the IPFS of Chain of Custody, to make the block data being stored in IPFS can not
It distorts, guarantees safety transparent.
As a kind of embodiment of the invention, the method also includes obtaining the block data saved into IPFS
File index, and save to the text space of main chain (transaction memo).It is different from the storage mode of the file index of the prior art,
The present patent application, which stores the file index, ensure that the file index of storage can not be distorted and pacify to the text space of main chain
All-transparent.
As one embodiment of the present invention, the method also includes by the block summary info of the block data
It saves to the text space of main chain.The present patent application stores the block summary info to the text space of main chain, ensure that
The block summary info of storage can not distort and safety transparent.
As one embodiment of the present invention, as shown in Fig. 2, being taken out first for the block data in business chain block
Number of transaction (i.e. number of data) and the block data summary info in block are taken, then the first Hash of calculation block data again
Value；Third saves block data into the IPFS of Chain of Custody, and obtains the file index of preservation；4th, by the transaction of acquisition
Quantity, summary info, the first cryptographic Hash and file index are saved into the transaction memo (i.e. text space) of main chain.The present embodiment
It is intended only as a kind of specific embodiment, is not used to limit other schemes that sequence changes or interactive mode changes.
As one embodiment of the present invention, the method also includes as shown in figure 3, institutionalized each business chain
Subchain in parallel as Chain of Custody.
Traditional solution relies on single business chain that business is unfolded, and the handling capacity of system is handling up for single business
Amount.In the present invention program, in parallel subchain of the institutionalized each business chain as Chain of Custody, using the solution of multichain,
Organically parallel connection is carried out to each business chain by Chain of Custody, in this way, Chain of Custody only needs to do interaction, the day of performance with business chain
The business stroke count that card (highest TPS) can not instead of at most not accepted, the quantity for the business chain accepted.Entire framework is handled up
Amount, is the summation of the handling capacity for all business chains being docked on Chain of Custody.And the business that Chain of Custody can theoretically carry
The quantity of chain is the handling capacity of Chain of Custody itself.Can make in this way the handling capacity (processing capacities of i.e. all chains) of entire frame at
It extends again.
