Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes.

In the embodiment of the present application, the equipment in block chain network can be privately owned equipment, carrier network devices (example Such as, base station equipment) or certain industry organization, the website (Station) of organization and individual's deployment.

In the embodiment of the present application, internet of things equipment can include but is not limited to mobile station (Mobile Station, MS), Mobile terminal (Mobile Terminal), mobile phone (Mobile Telephone), user equipment (User Equipment, UE), mobile phone (handset) and portable equipment (portable equipment), vehicle (vehicle) etc., for example, terminal device Can be mobile phone (or being " honeycomb " phone), the computer with wireless communication function etc., terminal device can also be Portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device.

In order to facilitate the application is understood, before the present processes are described, block chain is specifically introduced herein first The method of work of several elements in network, block chain network and the equipment in block chain network.

It should be noted that in the embodiment of the present application, the data that equipment generates include and the equipment and its opposite equip. phase The data of pass and common data.The method of work of equipment in element and block chain network in description block chain network When, with equipment and the relevant data instance of its opposite equip., specifically using with equipment and the relevant data of its opposite equip. to hand over Easy data instance is described, but this does not limit the range of the embodiment of the present application.

There is no the hardware of centralization or management organization in block chain network, the rights and duties between arbitrary equipment are all It is impartial, and any equipment damage or loss do not affect the running of entire block chain network, therefore, block chain network There is decentralization.Data exchange is carried out between each equipment in block chain network to be trusted each other, whole It is disclosed that the operation regulation of a block chain network, which is open and clear, all data content, therefore in block chain network In the range of regular scope and time, other equipment can not cannot be also cheated between equipment, therefore, block chain network, which has, goes The feature of trust.The total data block of block chain network safeguarded jointly by the equipment with maintenance function all in whole system, and Anyone can participate in during these equipment with maintenance function, and therefore, block chain network has the feature that collective safeguards. Block chain network allows each participation equipment that can obtain the copy of a full database by the form in divided data library.Unless Can control simultaneously in whole network be more than 51% equipment, it is invalid when otherwise on individual equipment to the modification of database, It can not influence the data content in other equipment.Therefore, block chain network has reliable database.

Block is the container data structures for having polymerize data being comprised in block chain, it includes member by one The block head of data and immediately after composition block main body a lot of transaction composition.Block specifically includes：Block size word Section, usually 4 bytes；Block head file, usually 80 bytes；Transaction counter field, generally 1-9 byte, note Record number of transaction；Transaction field, usually variable-length, records Transaction Details.

Block head is made of three group metadatas, is the data of one group of reference father's block cryptographic Hash first, this group metadata is used In the block is connected with the previous block in block chain.Second group metadata includes difficulty, timestamp and only with primary Number (Number used once, referred to as " Nonce ").Third element data are Mei Keer (Merkle) several (a kind of For effectively summarizing the data structure of All Activity in block).Block head specifically includes following field：Version field, usually 4 Byte；Father's block Hash value field, usually 32 byte, for quoting the cryptographic Hash of father's block in block chain；Merkle root words Section, for recording the cryptographic Hash of Merkle tree roots merchandised in the block；Timestamp field, usually 4 field, for tag slot The time proximity that block generates, is accurate to the second；Nonce fields are for the counter of proof of work algorithm.

Each block can quote previous block by " the father's block Hash value field " of its block head.Namely It says, each block head includes the cryptographic Hash of its father's block.And each father's block there are one blocks, but can be interim There are multiple sub-blocks.The situation that multiple sub-blocks occurs in one block is known as " block chain bifurcated ".Block chain bifurcated indicates one Transition condition, a final only sub-block can become a part for block chain.

Block chain, is the data structure being orderly chained up from back to front by block, and each block all points to previous area Block.It can be stored as a kind of file comprising non-relativeness record or be stored in a simple database.It can To regard block chain as a storehouse, highly mean that the distance between block and first block and top or top represent most New block.Each block head is encrypted Kazakhstan (for example, secure hash algorithm (Secure Hash Algorithm, abbreviation For " SHA ")), a cryptographic Hash can be generated.The correspondence block in block chain can be identified by this cryptographic Hash.

For entire block chain network, need target to be achieved be all devices agree to jointly some information and by it more Newly in total shared account book.For this purpose, introducing common recognition mechanism in block chain network, two kinds of typical algorithms are in common recognition mechanism Proof of work and equity prove.Wherein：

Proof of work (Proof Of Work, referred to as " PoW "), essence are to transmit to add in cost for information, reduce letter The rate of transmission is ceased, and it is wide into row information only to have the right there are one equipment in one random element one period of guarantee of addition It broadcasts.This random element is exactly that equipment is allowed to go to calculate a random Harsh value.Particularly as being input of the block equipment according to acquisition Data, be calculated a string 64 random digit and letter character string, but only obtain meeting the Hash of cryptographic Hash requirement The equipment of value can be received by block chain network as proof of work.And the hash algorithm of proof of work is also by will be each The mode of input value of a new life area information in the block as hash algorithm next time, realizes wearing for historical information, is formed Retrospective chain (block chain).

Equity proves, it is therefore an objective to realize that block chain is ensured that this method is logical by those people with economic interests The coin number of days (Coindays) of the destruction per transaction is crossed to realize that equity proves.Existing equity identity system, such as point point coin (Peercoin) it is based on evidence block, in evidence block, target and destruction coin number of days that miner must reach are negatives It closes.The digging ore deposit people that referred to as equity proves must be selected, and contribute their one whithin a period of time by possessing the people of Peercoin Part coin protects block chain network.

It will be described in detail at the data based on block chain according to the embodiment of the present application on the basis of above description below Reason method.As described in Figure 1, method 100 includes：

S101, the first equipment determine the block to be deleted in block chain network, and the first equipment is setting in block chain network It is standby；

S102, first equipment, which performs, deletes relevant operation, to delete block to be deleted.

Optionally, in S101, the first equipment can determine area according to the storage duration of block or the elapsed time of block Block to be deleted in block chain network.The storage duration of block, which is used to indicate block or area data in the block, to be needed in block link network Stored duration in network, elapsed time of block are used to indicate data needs that block or block include in block chain network In time for being deleted, the specific moment that the equipment in block chain network can be indicated in the elapsed time deleted in block or block Data, delete block or area's data in the block after the specific moment that can also be indicated in the elapsed time.For example, the first equipment It determines to wait to delete according to the relationship between the time interval between current time and the generation moment of block and the storage duration of block Except block.Or first equipment block to be deleted determined according to the relationship at current time and elapsed time.

For example, the first equipment minimum or minimum sequence number block of height from current block chain (distinguishingly, exists During initialization, since first block of block chain), determine the block to be deleted in block chain network.As shown in Figure 2 , the first equipment since block X, at the time of the first equipment determines that the timestamp of current time and block X are recorded between Time interval is greater than or equal to the storage duration of block X or when the first equipment determines the disappearance that current time is block X Between or when the first equipment determines that current time is later than the elapsed time of block X, the first equipment thinks block X to be to be deleted Block, the first equipment can directly delete block X, and the first equipment judges whether block X+1 is block to be deleted later, successively class It pushes away, until some block is not block to be deleted.Here current time (or current time) can be that the first equipment is given birth to At the time of the block of Cheng Xin or at the time of block chain that current block chain node broadcasts are new, the timestamp of block X record when It carves and includes for the generation moment of block X or the elapsed time of block X.

Alternatively, if the first equipment determines block X as block to be deleted, the first equipment does not delete block X, but by area The block information and deletion certification number (initial value 1) of block X is recorded in block chain, and block chain is broadcast to block chain network In, the value for deleting certification number can be increased by 1 by the equipment for obtaining certification power next time, until n-th gets certification power During equipment, deletion certification numbers of the block X in block chain network has reached preset value N, so n-th gets certification power Equipment block X is deleted from block chain.Later, this n-th get certification power equipment determine block X+1 whether be Block to be deleted, if block X+1 is block to be deleted, the equipment that n-th gets certification power can be by the block of block X+1 Information and deletion certification number (initial value 1) are added in block chain, and block chain is broadcast in block chain network, until When deletion certification numbers of the block X+1 in block chain network is N, the equipment in block chain network deletes block X+1, N's It is worth for preset value.

Alternatively, as shown in Figure 3, the first equipment determines whether the continuous K block since block X meets deletion Condition, if continuous K block is satisfied by deletion condition, this K block is determined as block to be deleted by the first equipment.First sets For can directly delete the continuous K block since block X, the first equipment judges continuous L since block X+K later Whether continuous block meets deletion condition, if it is satisfied, the first equipment deletes the continuous L block since block X+K.Successively Analogize, until certain multiple continuous block not exclusively meets deletion condition position, the value of K and L can be identical here, can not also Together.And the value of K and L can be the numerical value of dynamic configuration.

Alternatively, if the continuous K block that the first equipment determines since block X were satisfied by as block to be deleted, first Equipment does not delete the continuous K block since block X, but by the block information of the continuous K block since block X It is recorded in block chain with certification number (initial value 1) is deleted, block chain is broadcast in block chain network, is obtained next time The value for deleting certification number can be increased by 1 by the equipment of certification power, when n-th gets the equipment of certification power, from block X Deletion certification number of the K block of beginning in block chain network has reached preset value N, so n-th gets certification The equipment of power deletes the K block since block X from block chain.Later, the equipment that this n-th gets certification power Determine whether the L since block X+K continuous block is satisfied by deletion condition, if the L continuum since block X+K Block is block to be deleted, and the equipment that n-th gets certification power can be by the block of the L continuous blocks since block X+K Information and deletion certification number (initial value 1) are added in block chain, and block chain is broadcast in block chain network, until When deletion certification number of the continuous L block in block chain network since block X+K is N, setting in block chain network The standby L continuous blocks by since block X+K are deleted.

In the above-described embodiments, optionally, if the first equipment determine continuous K block since X there are one or It is multiple to be unsatisfactory for deletion condition.First equipment can will meet deletion condition at this time area's data in the block in continuous K block It deletes, but retains the block head of these blocks.Until some equipment in block chain network determines the continuous K area since X When block is satisfied by deletion condition, this continuous K block is deleted.Alternatively, by the block information of this continuous K block and delete certification Number is recorded in block chain, and block chain is broadcast in block chain network, until some equipment in block chain network is true When the deletion certification number of this fixed continuous K block is N, this continuous K block is deleted.

It should be noted that above-mentioned deletion condition was referred between current time and the time generated between the moment of block The elapsed time that current time is block is referred to every the storage duration more than or equal to block or above-mentioned deletion condition, Or above-mentioned deletion condition refers to that current time is later than the elapsed time of block.

In above-mentioned all embodiments, optionally, block information is recorded in the block chain of block chain with certification number is deleted In head.

Optionally, in S101, the first equipment can according to whether carried in block chain block information and delete certification Number determines block to be deleted.

Specifically, in some embodiments, if carrying block information in block chain and deleting certification number, first The block that block information indicates is determined as block to be deleted by equipment.

Further, if the first equipment determines that the value for deleting certification number is less than preset value, the first equipment will delete After the value of number increases by 1, the equipment into block chain network sends above-mentioned block information and deletes certification number, Zhi Daoqu When the deletion certification number recorded in block chain is preset value, the equipment in block chain network deletes the block that block information indicates It removes.

If the first equipment determines that the value for deleting certification number is preset value, the first equipment can directly delete block letter Cease the block of instruction.
