Cease the information of list ModuleCheckList.
Further, it also needs to design the algorithm for generating a new block by a block in the embodiment of the present invention.
The client of each block chain can then receive the original block that server issues, and then then can be generated according to original block
It new block and is added in block chained list, is implemented as follows：
We have got the data structure of a upper block first, and next block is then according to a upper block
Data generated.The name that a upper block is assumed in the present embodiment is prevblock, and the name of newly-generated block is
newblock。
(1) block number of new block is calculated.
Newblock.index=prevblock.index+1；
Then the block number of new block is that current block number adds 1.
(2) timestamp of new block is calculated.
Newblock.timestamp=time ()；
The timestamp of new block is then to obtain the current time.
(3) the hash value of a upper block for new block is calculated.
Newblock.previousHash=prevblock.hash；
The hash value of a upper block for new block is then the hash of the upper block obtained.
(4) data of new block are calculated.
Newblock.data=data+ModuleCheckList；
When official's client release is updated, then a new block can be generated, it then can be comprising new in new block
The complete information of the module check information list ModuleCheckList of all modules of released version.
(5) the randdata value of new block is calculated.
This randdata value is then that client generates at random, to gather together enough before the hash value that just entire new block calculates
Meet 0 number that server issues.
(6) the hash value of new block is calculated.
Newblock.hash=HASH (index+previousHash+timestamp+data+zero+randdata)；
The hash value of new block is then to have the index field and previousHash field and timestamp word of new block
Section and data field.
HASH algorithm used in it is usually SHA-256 algorithm, naturally it is also possible to other HASH algorithms are used, such as
SHA-1, MD5 etc..

Then can all be gone when receiving a new block sender for verifying new block identity be official's client identity letter
Breath, if not will not then be added in block chain, it is believed that this is the unique ID of equipment of a forgery.So each block needs
Carry out completeness check.It is implemented as follows：
Common, in addition to original block, is then that client has had current block first for other blocks in client,
Then a new block is had received, needs to carry out validity judgement to new block.It is implemented as follows：
The name for also assuming that a block is prevblock, then has received the name of a newly-generated block
It is newblock.
(1) first determine whether its index is correct.
Newblock.index！=prevblock.index+1；
If the block index of new block is not the block number plus 1 of a upper block, illustrate that new block does not conform to
Method, directly return block errors information.
(2) then judge the hash value of block.
Newblock.previousHash！=prevblock.hash
New area is thought if the hash value of a upper block for new block is not equal to the hash value of a upper block
Block is illegal, directly return block errors information.
(3) judge the hash value of new block.
The hash value of new block is the hash result of the entire data of new block.
HASH(Newblock.index+Newblock.previousHash+Newblock.timestamp+
Newblock.data+Newblock.randdata+Newblock.zero)！=Newblock.hash；
If the hash value of the data of the entire block of new block is not equal to new block hash value, then it is assumed that new area
Block is illegal, directly return block errors information.
(4) judge the identity information of client official publisher.
When needing to issue new client, then new client release block can be generated, and can in new block
With the check information ModuleCheckList comprising all modules of entire client.In order to further ensure safety, official's publication
The private key information of oneself can be used to encrypt to ModuleCheckList information in person, and all clients then all have official
The public key information of square person, so that data be decrypted by public key, if the information decrypted be all it is correct complete,
Be not messy code information, then illustrate that this information is the information of official publisher, if this information decrypts be messy code if say
The official information for the method that makes a clear distinction between right and wrong.
