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 the client in live platform target room, then should The client in target room receives after original block chain, it is necessary to which algorithm generates next block chain.It is implemented as follows:First The data structure of a upper block chain is got, next block chain is then the data progress according to a upper block chain Generation.

In the embodiment of the present invention, above-mentioned steps S104 generates record according to the first block chain has second transaction to remember Second block chain of record can specifically include:

According to the block number of the first block chain plus 1, the block number of the second block chain is obtained;

Obtain current time;

The cryptographic Hash of the first block chain is calculated, the cryptographic Hash as previous block chain in the second block chain;

Obtain the room number in the target room, user's mark of the client, the mark of the client and current Second transaction data, obtain the second block chain performance data;

To the block number of the second block chain, current time, the cryptographic Hash of the first block chain and second block Chain performance data carries out Hash calculation, obtains the cryptographic Hash of the second block chain;

According to the block number of the second block chain, current time, the cryptographic Hash of the first block chain, second block The cryptographic Hash of chain and the second block chain performance data, according to the second block chain described in the data structure building.

Specifically, in the embodiment of the present invention, it is assumed that the name of a upper block chain is prevblock, newly-generated block The name of chain is newblock, and 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=time ();

The timestamp of new block chain is then to obtain the current time.

(3) the hash values of a upper block chain for new block chain are calculated.

Newblock.previousHash=prevblock.hash;

The hash values of a upper block chain for new block chain are then the hash of the upper block chain obtained.

(4) the key values of a upper block chain for new block chain are calculated.

Newblock.key=prevblock.key;

The key values of a upper block chain for new block chain are then the key of the upper block chain obtained.

(5) new block chain performance data is calculated.

Still exemplified by beating the live platform room main broadcaster of reward.

Newblock.data=giftnum+senduid+givegiftnum+receiveuid

Wherein giftnum is then the surplus of the present quantity of active client, and senduid is then the use of active client Family identifies uid, and givegiftnum is then the present quantity for beating reward, and receiveuid is then the uid for the client for being beaten reward.

Newblock.data=AES.encrypt (Newblock.data, Newblock.key);

The data data of new block chain are then to be used together AES AES by all of the above data to be carried out to data Further encryption, wherein the key values that the key values used, which are then servers, to be issued.Certain AES can also use more Complicated AES.

(6) the hash values of new block chain are calculated.

Newblock.hash=HASH (index+previousHash+timestamp+data+key);

The hash values of new block chain be then have new block chain index fields and previousHash fields and Timestamp fields and data fields and key 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 the embodiment of the present invention, either client or server, first all can be right when it receives a block chain Block chain carries out legitimacy verifies, to judge whether current block chain is legal, to prevent hacker from forging block chain, or Block chain transmits the factor such as changed in a network.So each block chain is required for carrying out completeness check.Therefore, it is of the invention Method can further include in embodiment:

The client is when receiving the 3rd block chain that destination client is sent in the target room, described in verification The legitimacy of 3rd block chain.

In the embodiment of the present invention, the step of client verifies to the block chain received, can specifically include:Assuming that The name of a upper block chain is prevblock, and the name that then have received a newly-generated block chain is newblock.

(1) first determine whether its index is correct.

Newblock.index!=prevblock.index+1;

If the block number of new block chain is not the block number plus 1 of a upper block, illustrate that new block chain does not conform to Method, directly return to block chain error information.

(2) the hash values of block chain are judged.

Newblock.previousHash!=prevblock.hash

Think if hash value of the hash values not equal to a upper block chain of a upper block chain for new block chain New block chain is illegal, directly returns to block errors information.

(3) the hash values of new block chain are judged.

The hash values of new block chain are the hash results of the whole data of new block chain.

HASH(Newblock.index+Newblock.previousHash+Newblock.timestamp+ Newblock.data+Newblock.key)!=Newblock.hash;

If the hash values of the data of the whole block chain of new block chain are not equal to new block chain hash values, then it is assumed that New block chain is illegal, directly returns to block chain error information.

(4) the data values of new block chain are judged.

Data are encrypted by AES for the data values of new block chain.Then can ciphertext data in this step To judge the legitimacy of data.

Newblock.data=AES.decrypt (Newblock.data, Newblock.key);

So as to obtain original data data after now data fields are decrypted, it can be then learnt from data Giftnum, senduid, givegiftnum, receiveuid, it may then be made whether that giftnum is greater than Givegiftnum's.
