As shown in Fig. 2 the server issue the first block chain to the roomed all clients of live platform institute it
Before, method can further include in the embodiment of the present invention：
S105, server generate the first block chain.
In the embodiment of the present invention, the first block chain and the second block chain can have identical data structure；
The data structure can include the block number of block chain, the cryptographic Hash of previous block chain, the timestamp and block of current time
Chain performance data, the block chain performance data are the random data that the server generates at random, or solid for generation one
Determine to fill obtained data after data encryption, now, the data structure of the first block chain can be the data knot of foregoing description
Structure, the first block chain can include the block number of the first block chain, the cryptographic Hash of previous block chain, the timestamp of current time
And block chain performance data, the block chain performance data are the random data that the server generates at random, or it is generation
Obtained data are filled after one fixed data encryption.In the embodiment of the present invention, above-mentioned data structure is implemented as follows：
Struct BlockData{
Int64index；
String previousHash；
Int64timestamp；
String data；
String hash；
}
Wherein, index is used for representing the block number of block chain, is incremented by generally since 0；PreviousHash represents previous
The HASH values of block chain；Timestamp represents current time stamp；Data then represents splicing (the i.e. above-mentioned block chain of some data
Performance data), the content of this data field is then according to designed by the function of being completed required for block chain, is directed to this paper's
All room popularities are detected, block chain performance data data can be that server generates one piece of data at random, and this data is to all
Client all uses same value, fills this value during server initiation, client then directly takes this when generating new block chain
Value；Hash then represents the hash values of the content of this current block chain.After the design for having this block chain, when server receives
Client, then can be by verifying, to judge its legitimacy newly after caused block chain to the data of the inside.
In the embodiment of the present invention, the first block chain can be the original block chain of server generation, when the first block chain is
During original block chain, original block chain is due to being first block chain generated, and the block number of original block chain is 0, timestamp
It is then current time, the hash values of a upper block chain are 0, and block chain performance data (above-mentioned data data) is then entered for server
The random generation of row, server are generated to fill after a fixed data is encrypted and obtained.
The algorithm that new block chain generates in block chain, block chain initial first are devised in the embodiment of the present invention simultaneously
It is that server generates (such as the first block chain), server can be issued to each client for logging on live platform target room
End, then the client in the target room receives after original block chain, it is necessary to which algorithm generates next block chain.Specific implementation
It is as follows：The data structure of a upper block chain has been got first, and next block chain is then according to a upper block chain
Data generated.
In the embodiment of the present invention, it is assumed that the name of a upper block chain is prevblock, the name of newly-generated block chain
It is newblock, the process for specifically generating new block chain is as follows：
(1) block number of new block chain is calculated.
Newblock.index=prevblock.index+1；
The block number of i.e. new block chain is that current block number adds 1.
(2) timestamp of new block chain is calculated.
Newblock.timestamp=prevblock.time；
In the embodiment of the present invention, the timestamp of new block chain then uses the timestamp of a upper block chain, because if making
With the current time, then the Time Inconsistency that each client is got is likely to result in, so as to cause the hash finally calculated
It is worth inconsistent, ultimately results in legal client and the equal block chain of one result cannot get according to identical block chain.
(3) the hash values of a upper block chain for new block chain are calculated.
Newblock.previousHash=prevblock.hash；
Wherein, the hash values of a upper block chain for new block chain are then the hash values of the upper block chain obtained.
(4) the block chain performance data of new block chain is calculated.
Newblock.data=prevblock.data；
The data data of new block chain are then generated at random by server, then filling is that data are that server issues
The data of block chain, it in order to reach the new block chain value ultimately generated is one that why so design, which is, in the embodiment of the present invention
Sample, if filling out room number or user uid, then the new block chain for eventually resulting in each client all differs
Sample.
Certainly, in the embodiment of the present invention, server can also classify to different live rooms, such as according to plate
To classify, different plates inserts different random value (block chain performance data), so carries out school to different versions
Test, the block chain data of the client corresponding to each plate below room are then the same certainly, can so prevent for
The fewer room of popularity, if the substantial amounts of false client of brush, can prevent this special circumstances.In some implementations of the present invention
In example, block chain performance data can also all use a same random value to all rooms.
(5) the hash values of new block chain are calculated.
Newblock.hash=HASH (index+previousHash+timestamp+data)；
Wherein, the hash values of new block chain be then have new block chain index fields and previousHash fields and
Timestamp fields and data fields.
In the embodiment of the present invention, Hash corresponding to cryptographic Hash (HASH) algorithm is unified, and the HASH algorithms can be SHA-256
Algorithm, naturally it is also possible to be other HASH algorithms, such as SHA-1 etc., be not construed as limiting herein.
So far, the algorithm that a new block chain is generated by a block chain is achieved that by above-mentioned steps.And this
In inventive embodiments, when client generates the second block chain by receiving the first block chain, i.e., realized using above-mentioned steps.
In addition, in the embodiment of the present invention, the data verification method can further include：If the server receives institute
Have the second of the destination client transmission for not having the live platform target room in all second block chains of client return
Block chain, and the destination client is current still in the target room, it is determined that the destination client is illegal client
End.So it is due to that the client of the brush popularity having has not been aware of the verification of a newly-increased block chain, and normal client
End then can all carry out reporting new block chain, therefore it is non-that can directly determine that this does not return to the destination client of the second block chain
Method client.
In some embodiments of the invention, as shown in figure 3, above-mentioned steps S103 can specifically include：
S1031, server are using each second block chain in all second block chains as a numerical value；
S1032, server determine that the numerical value that quantity is most in all numerical value is Constant numerical values, by corresponding to Constant numerical values
Two block chains are defined as the second legal block chain, other for the second illegal block chain.
In the present embodiment, after server issues the first block chain, the second new block that legal client is calculated
Chain numerical value is the second new block chain the same, that server is reported by the client received, is obeyed by majority a small number of
Principle, it is believed that the quantity of the second new block chain of identical it is maximum be correct second block chain, and measure and on the low side then recognize
To be the second illegal block chain so that server and the second block chain that need not be reported to each client carries out legitimacy
Verification, has greatly subtracted the calculating pressure of server, server need not be calculated, it is only necessary to the knot of the second block chain
Fruit carries out distributed number to determine legal block, also utilizes the core concept of block chain, the minority is subordinate to the majority, goes to center
The thought of change.
