Safety.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those skilled in the art's every other implementation obtained without making creative work
Example, shall fall within the protection scope of the present invention.
The description and claims of this application and term " first ", " second ", " third ", " in above-mentioned attached drawing
The (if present)s such as four " are to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should manage
The data that solution uses in this way are interchangeable under appropriate circumstances, so that the embodiments described herein can be in addition to illustrating herein
Or the sequence other than the content of description is implemented.In addition, term " includes " and " having " and their any deformation, it is intended that
Cover it is non-exclusive include, for example, containing the process, method, system, product or equipment of a series of steps or units need not limit
In step or unit those of is clearly listed, but may include be not clearly listed or for these process, methods, produce
The other step or units of product or equipment inherently.
Referring to Fig. 1, be the flow chart of the date storage method provided in an embodiment of the present invention based on block chain, it is specific to wrap
It includes:
101, block catenary system generates block subchain.
Block catenary system generates block subchain, and block subchain includes file uplink time, and file uplink time is used to indicate
File destination is uploaded to the initial time of interspace document transmission system IPFS.
It should be noted that increasing a storage assembly (Storage Task) in block catenary system, it is distributed in networking
Comprising the storage assembly that can be called by block chain node in formula system structure, storage assembly includes interspace document transmission system
(interplanetary file system, IPFS) program and corresponding library file etc..
Block catenary system may include application service layer, kernel service layer and protocol layer, wherein application service layer includes number
According to transmission assembly, authentication component, data Synchronization Component, data protection component, Software Development Kit (software
Development kit, SDK) and application programming interface (Application Programming Interface,
API), kernel service layer include dynamic common recognition (Dynamic Consensus) component, safety (Safty Strategy) component,
It calculates power and plans as a whole (CoC Planning) component, AI collaboration (Artificial Intelligence Synergism) component and body

It is understood that block catenary system needs to configure storage assembly and initializes before generating block subchain, tool
Body, a control of the storage assembly as block chain is installed, ipfs automatically in the complete client of installation block chain
For program name.For example, ipfs init can be in storage assembly for installing the complete client of block chain in Linux system
Local storage space is initialized when primary operation, and default storage space such as 2G is set；Initialization is completed to execute order ipfs
Daemon, starter node server are added IPFS network, wait IPFS subsequent commands to be processed.
102, block catenary system uploads file destination by the way that whether the token quantity that block main chain inquires this address meets
Quantitative requirement.
Whether block catenary system meets the quantity for uploading file destination by the token quantity that block main chain inquires this address
It is required that the token is used to pay the remuneration for uploading file destination to IPFS.If token quantity meets the quantity for uploading file destination
It is required that thening follow the steps 103.The space that IPFS shares is combined by each IPFS contributes, and needs the remuneration certain to universe network
It just can be carried out upload.
It should be noted that the structure of block subchain includes block size, block head, file counter and file content,
The length of block size field is 4 bytes, with the block size after the field of byte representation；The length of block head file is
80 bytes, several fields including forming block head；The length of file counter field is 1-9 byte, the sheet which includes
Block quantity of documents；The indefinite length of file content field, the file information being recorded in block use primary the file information
Format, and the position in file must be with the leaf node sequence consensus of Merkel tree tree.
Wherein, the data structure of block head includes version, father's block head cryptographic Hash, Merkel Merkle root, timestamp, difficulty
Spend target and random number N once.The length of version field is 4 bytes, records block version number, indicates the verifying that this block is abided by
Rule；The length of father's block head cryptographic Hash is that 32 bytes are calculated for indicating the cryptographic Hash of previous block using SHA256；It is silent
The length of Ke Er Merkle root is 32 bytes, and the Merkle tree root cryptographic Hash of the block All Files is equally counted using SHA256
It calculates；The length of timestamp is 4 bytes, which generates time proximity, be accurate to the UNIX timestamp of second, must be strictly larger than preceding 11
The intermediate value of a block time, full node can also refuse those blocks for exceeding oneself 2 hour timestamp；The length of difficulty target
For 4 bytes, the difficulty target of the block proof of work algorithm is encoded using special algorithm；The length of random number N once is 4
Byte meets random number set by difficulty target to find, and is used for adjustment difficulty, and adjustment is packaged block time interval.
For example, the structure of single file storage data include version field, input counter field, file Hash field,
Transaction output index field, sequence number field, file home address field, file size field, file uplink time field, lock
Determine Script Field, locking time field.Wherein, the length of version field is 4 bytes, is used to indicate the rule of this transaction reference
Then；The length for inputting counter field is 1-9 byte, is used to indicate the file input quantity for including；The length of file Hash field
Degree is 32 bytes, the file hash value calculated by SHA256 ()；The length of transaction output index field is 4 bytes, and format is solid
It is set to 0xFFFFFFFF；The length of sequence number field is 4 bytes, value all 1, format 0xFFFFFFFF；File ownership place
The length of location field is 1-9 byte, the address comprising file owner；The length of file size field is 8 bytes, with byte table
The file space size shown；The length of file uplink time field is 4 bytes, when indicating that file is added to the starting of IPFS system
Between；The indefinite length for locking Script Field defines the script of condition needed for file shifts；It is 4 that locking time field, which obtains length,
Byte is a block number or specified UNIX timestamp.
