Step S202, user node carry out the signature for authentication and broadcast to data Transaction Information.
After user node structure data trade information, data Transaction Information is carried out using oneself privately owned private key to be used for body
The signature of part certification, and the whole network is broadcast to, facilitate each node of the whole network to receive the data trade information.
Step S203, multiple memory nodes for treating selection judge whether to preserve to be stored according to the data trade information of broadcast
File.
Multiple memory nodes after selection, can be according to data after the data trade information that uppick user node is broadcasted
Transaction Information is to determine whether preserve file to be stored.As multiple memory nodes for treating selection are carried according in data trade information
The size of file to be stored, storage duration, transaction payment amount be to determine whether file to be stored will be preserved, if treating selection
Memory node thinks to have enough space storage files to be stored, storage duration, transaction payment amount rationally etc. can perform step
Rapid S204.Or treat that the memory node of selection does not have enough space storage file to be stored, storage duration and transaction payment gold
Volume can not do any place compared to unreasonable (amount of money is too low) etc. after the data trade information that uppick user node is broadcasted
Reason.
Step S204, multiple memory nodes for treating selection are downloaded file to be stored and are preserved.
Multiple memory nodes when selection, can be according in data trade information when judging to preserve file to be stored
File to be stored is downloaded in magnetic force link, saves it in the local for the memory node for treating selection.
While multiple memory nodes for treating selection download file to be stored, (file byte can be accumulated the byte age
The number * times).The accumulation at byte age can be used for weighing the preservation file to be stored whether memory node fulfils the duty, and be additionally operable to count
Whether the storage time for calculating file to be stored has reached the storage duration that user node is specified.
Step S205, multiple memory nodes for treating selection carry out multiple first receipts for the signature of authentication and wide
Broadcast.
After multiple memory nodes after selection are downloaded and preserve completion file to be stored, multiple memory nodes for treating selection
The first receipt can be generated.Wherein, the first receipt includes file to be stored Hash, the storage time of file to be stored, file and deposits
Store up the information such as information.Multiple memory nodes for treating selection carry out the first receipt the signature for authentication and broadcast to complete
Net.
Step S206, user node are detected multiple memory nodes for treating selection, judge multiple storages for treating selection
Whether node completely downloads file to be stored.
User node can be preserved the first receipt after the first receipt of uppick.Then selection is treated to multiple
Memory node is detected.Specifically, user node is detected multiple memory nodes for treating selection using detection algorithm, inspection
The purpose of survey is used to judge whether multiple memory nodes for treating selection completely download file to be stored, in order to avoid treat the storage section of selection
The file to be stored that point is downloaded is imperfect.Detection algorithm can be such as to inquire multiple memory node specified file fragments for treating selection
Cryptographic Hash.User node can randomly select offset and length in file to be stored, extract file to be stored
This segment data, calculates its cryptographic Hash.The each memory node for treating selection for having downloaded file to be stored is required to provide at the same time same
The cryptographic Hash of sample offset and the file to be stored of the length segment data.User node detects each memory node meter for treating selection
Whether the cryptographic Hash of calculation and the result oneself calculated are consistent.After random detection above-mentioned several times, if cryptographic Hash is equal every time
Equally, it may be considered that file to be stored is downloaded completely by each memory node for treating selection.Alternatively, it can also allow multiple
Treat a hash algorithm calculation document Hash (the whole file to be stored calculating that the memory node of selection is specified using user node
File Hash), the result obtained with user node oneself calculation document Hash is verified, can be with if result of calculation is consistent
Thinking file to be stored has been treated, the memory node of selection is downloaded completely.Complete download the multiple of file to be stored are waited to select
Memory node, continue to execute step S207；Multiple memory nodes for treating selection to not downloading file to be stored completely, no
Do any processing.
Alternatively, the first receipt of the memory node to not downloading file to be stored completely can abandon, not to it
Carry out subsequent treatment.
Further, can also mutually be detected between multiple memory nodes, as randomly selected text to be stored between memory node
Offset and length in part, extract this segment data of file to be stored, calculate its cryptographic Hash.Require other storages at the same time
Node provides the cryptographic Hash of same offset and the file to be stored of the length segment data, to detect whether the knot calculated with oneself
Fruit is consistent.So can in order to reject falseness memory node.Can also be by exchanging each storage between multiple memory nodes
The specified portions data message of file, detects whether the presence of false memory node.Pass through the phase between multiple memory nodes
Mutually detection, can be supplied to and preferably be serviced to user node.
Step S207, user node is according to corresponding to the first receipt that default Algorithms of Selecting chooses one or more broadcast
Memory node of the memory node as storage file to be stored.
The memory node that user node can detect to have downloaded file to be stored completely through step S206, further according to
Default Algorithms of Selecting chooses final memory node from these memory nodes.User node is therefrom selected according to default Algorithms of Selecting
One or more corresponding memory node of the first receipt is taken as the final memory node for preserving file to be stored.Default choosing
It can be random algorithm to take algorithm, or deterministic algorithm.It is high in view of the computational efficiency of deterministic algorithm, preferably using
Deterministic algorithm.As hashing algorithm safe to use (Secure Hash Algorithm, abbreviation SHA) treats that selection is deposited to multiple
Storage node rems, then spaced pick, chooses final memory node.During implementation suitable certainty is selected according to actual conditions
Algorithm, does not limit herein.
Step S208, user node carry out the first receipt of selection the signature for authentication, obtain the second receipt
And broadcasted.
User node carries out signature for authentication to the first receipt of selection using private key, that is, indicate selection these
The corresponding memory node of first receipt is as final memory node.User node is signed to obtain second time to the first receipt
Hold.The information such as file to be stored Hash, the storage time of file to be stored, file storage information are contained in second receipt and are deposited
Store up the signature of node.Meanwhile second signature that further comprises user node in receipt.User node broadcasts the second receipt to complete
Net.Memory node can preserve second receipt according to the signature of oneself in the second receipt.
Step S209, what user node broadcast carried the second receipt fetches instruction.
When user node needs to fetch stored file to be stored, user node broadcast carries the second receipt
Instruction is fetched to the whole network.Wherein, the second receipt randomly selected for user node from multiple second receipts one or more the
Two receipts, to fetch the file to be stored that corresponding memory node is stored.User node chooses multiple second receipts, to prevent
Only problem occurs for some memory nodes, can not return to file to be stored.As memory node releases file to be stored in advance, delays
Machine, network signal are bad to be connected.
Step S210, memory node obtain corresponding storage file and return to use according to the second receipt fetched in instruction
Family node.
After instruction is fetched in memory node uppick, according to fetch on the second receipt that instruction carries oneself sign, text
Part storage information (such as file storage address information) can find the file of corresponding storage from disk, and (i.e. user node is treated
Storage file).
The information such as the IP address of user node can also be included by fetching in instruction, facilitate memory node can be with user node
Point-to-point connection is established, corresponding storage file is directly returned to user node.Avoid storage file excessive, the whole network broadcast is made
The problems such as into network blockage.Further, when user node broadcast fetch instruction in carry multiple second receipts when, Duo Ge
The corresponding multiple memory nodes of two receipts return to storage file to user node.User node can according to the needs of oneself,
Any one memory node of random selection, preserves the storage file of memory node return, and other memory nodes are returned
Storage file no longer preserves；Or the storage file that can also be returned to multiple memory nodes preserves, convenient backup etc. needs
Ask.
Step S211, discharges stored file to be stored, obtains the transaction payment amount that user node is paid.
In the case where the storage time of file to be stored exceedes storage duration, memory node can be by broadcasting second time
Hold to obtain the expense of file to be stored.If memory node broadcast is for the second receipt of intelligent contract, according in the second receipt
The signature of user node and the signature of memory node, can get the transaction payment gold that user node is paid in intelligent contract
Volume.Memory node understands the active broadcast after file to be stored reaches storage duration to obtain transaction payment amount.Second receipt
In have recorded the storage time of file to be stored, detect the storage time of current time-file to be stored value whether be more than or
Equal to storage duration, if more than or equal to store duration, i.e. memory node has completed the storage duration of user node requirement, can
To discharge stored file to be stored, and obtain the transaction payment amount of user node payment.It is also assumed that storage section
Point gets the transaction not spent output (the Unspent Transaction of a passage time (storage duration) locking
Outputs, abbreviation UTXO).After storage duration is reached, the spendable amount of money of memory node is automatically become.Unlock can use
The whole network common recognition is unlocked, and effectively prevents memory node from getting transaction payment amount in advance.
The decentralization date storage method provided according to the present invention, effectively have detected whether memory node completely preserves
File to be stored, has ensured the integrality of file to be stored.When user node is fetched, memory node can be by point-to-point direct
File is returned into user node, reduces network blockage.Memory node can be after storage duration be reached, and active broadcast second returns
Hold, to obtain the transaction payment amount of user node payment.
