}
After having the design of this block, any one spectators receives a block then can carry out school to block data
It tests, so far completes the design of the data structure of block in block chain.
When client application software needs update for the first time, client reports the file that needs are updated, server meeting
To each generation original block that newer file is needed to calculate its file content.It is implemented as follows：
Step 1 reads each need in newer file to memory.
First, each independent newer file of needs is read, the content of entire file is read in memory.The present invention
Specifically update file can be read in embodiment using system function fopen and fread.
FILE*pFile=fopen (" beauty.data ", " rb ")；
The update file specified is opened by calling system function fopen.
Wherein parameter 1 is open update file name.
Wherein parameter 2 is then to open update file in a manner of binary.
Return value is then the handle pFile of file.
fseek(pFile,0,SEEK_END)；
By calling fseek functions that the reading pointer of file then is moved to tail of file.
Long Size=ftell (pFile)；
The size Size of update file is then obtained by calling system function ftell.
Char*buffer=(char*) malloc (Size)；
Calling system function malloc distributes one section of memory, and allocated size is then the size for updating file.
fread(buffer,1,Size,pFile)；
Calling system function fread is read in entire file content to the memory of distribution.
fclose(pFile)；
Calling system function fclose closes file handle.
So as to which the content of entire update file read in the memory of distribution.
Step 2, the Md5 values for calculating entire update file.
The embodiment of the present invention calculates its MD5 value so as to obtain subsequently encrypting what is used by the entire update file to reading
KEY values.
KEY=MD5.Create (buffer, Size)；
By calling the interface Create of MD5 functions its MD5 result is calculated to calculate the file content of reading.
Wherein parameter buff is then the memory of update file read.
Wherein parameter size is then the size of update file read.
The MD5 value of each file is similarly all calculated all update files using above-mentioned scheme.
Step 3, the MD5 values for calculating each update file.
The HASH results of its MD5 are calculated to each update file of client.
Step 4, server generate the block of upgrading client software.
In the present embodiment, block data structures are as follows：
Struct BlockData{
Int64index；
String previousHash；
Int64timestamp；
String key；
String data；
String zero；
String randdata；
String hash；
}
Wherein core is then data fields, which can then include the content for needing newer client update file,
The MD5 values of more new content are also included simultaneously.It after server produces this original block, then can be synchronized in block chain, so as to logical
It crosses block chain and is synchronized in all block chain clients to distribute.
Further, it after the original block that server generates, needs again to carry out more client application when follow-up
When new, then the generation of new block is directly realized by the intelligent contract in block chain network, this stylish block can then pass through P2P
Be transmitted to all clients in room, at the same when all clients receive block the data of block can also be carried out it is legal
Property verification.The realization for specifically generating new block is as follows：
First, the block data and block data structures of a upper block for the target block have been got, it is next
Block is generated according to the block data and block data structures of a upper block.
In a specific embodiment, it is assumed that the name of a upper block is prevblock, newly-generated block, that is, target
The name of block is newblock.
1st, the block number of target block is calculated.
Newblock.index=prevblock.index+1；
Then the block number of target block is the block number plus 1 of a upper block.
2. calculate the timestamp of target block.
Newblock.timestamp=time ()；
The timestamp of target block is then to obtain the current time.
3. calculate the hash values of a upper block for target block.
Newblock.previousHash=prevblock.hash；
The hash values of a upper block for target block are then the hash of the upper block obtained.
4. calculate the key values of a upper block for target block.
Newblock.key=prevblock.key；
The key values of a upper block for target block are then the key of the upper block obtained.
5. calculate the data of target block.
Newblock.data=file contents+md5.
Wherein the data content of target block is then the content for updating file and the MD5 values of update file.
6. calculate the randdata values of update file.
This randdata value is then that client generates at random, to gather together enough before the hash values that just entire target block calculates
Meet 0 number that server issues.
7. calculate the hash values of target block.
Newblock.hash=HASH (index+previousHash+timestamp+data+zero+randdata)；
The hash values of target block are then the index fields, previousHash fields, timestamp by target block
Field, data fields.
The HASH algorithms used in the present embodiment are typically SHA-256 algorithms, naturally it is also possible to be calculated using other HASH
Method, the present invention are not specifically limited this.
