Specific embodiment
The block account book structure of block chain is as shown in Figure 1, account book block includes block data, block index in the present invention./
Mychannel under chains/chains is channel name and account book name, before store under the catalogue and being with blockfile_
Sew, 6 bit digitals are the block data of the entire account book of suffix, block index are store under/chains/index, with levelDb
Form storage.Block data is the main contents of entire block, includes the All Activity information in entire block, trades every time
Book keeping operation is completed, and will all increase a tile system file (blockfile_xxxxxx) newly under mychannel catalogue, and update
LevelDb (block index) under index catalogue.
Account book block storage mode is had changed in the present invention, and a block file is stored into multiple blocks or a block changes
A block is only stored for a block file.
Newly-increased block is stored to blockfile, is added by file manager, in blockfile_mgr.go
In, memory block is not done compared with the remaining storage size of current block file, and it is big that block size is assigned to block file
Small maxBlockfileSize, directly execution moveToNextFile (), newly-built blockfile simultaneously adds block, real
Existing one block of a block file, which is block file size.It is as follows to modify code:
CheckpointInfo information is updated, database is saved to.
Block index is created by blockIndex, such as block reference number of a document, account book id, and is saved to slip condition database
In, update world state.
Inquiry block is searched according to block reference number of a document, executes method successively are as follows:
Account book is navigated to by ledgerId (channel name or account book name)；
Tile system file is navigated to by blockfileNum；
The block content is returned.

Go out a transaction results according to current account book state computation, which includes return value, read-write collection.At this point, block chain account book is simultaneously
It will not be updated, endorsement result is back to client by endorsement node.
After client receives the information of endorsement (Endorser) node return, judge whether motion result is consistent, Yi Jishi
The no result (referring to specified endorsement strategy execution) for receiving enough endorsement nodes and returning, if without enough endorsements,
Then stop to handle, this transaction will be rejected.Otherwise, will transaction motion, mock trading result and endorsement information packing group at
It trades and signs for one and issue Orderer node (a sequence service).
Orderer node carries out common recognition sequence to the deletion Transaction Information from client, and subchannel presses transaction message
Time-sequencing, and by channel by delete transaction be packaged it is blocking, verifying (Committer) node is distributed to by gossip agreement.
Committer node verifies transaction block, is verified, and transaction block is added to account book block text
Part updates checkpoint information.
To trading, block type judges, Isdelete==true is to delete transaction, according to deletion transaction block
Content executes corresponding history account book block file and deletes.
According to deleting, the corresponding history account book block file deletion specific implementation step of transaction block content execution is as follows
It is called according to the key assignments in block and inquires tile system document method in chain code.
It obtains history account book block document location and positional value is put into fileString [] array.
[iteration fileString [] array executes history block delet method deleteBlockfile (), and code is as follows:
DeleteState () in chain code is called to delete the block index in slip condition database, more new historical account book data
Library.Here, it is that the corresponding value of key is set nil that block index, which is deleted,.
[Isdelete==false is more New Transaction, calls in chain code putState () by the area in slip condition database
Block index upgrade, and more new historical account book database.
