It is logged by, while transaction tx is recorded into account book.When the accounting nodes for being more than half in same section record the transaction
Afterwards, it is considered as and reaches common understanding, which can not distorts, and transaction successful information can be sent to user.
It is emphasized that in the context of the present invention, daily record and the account book concept that to be two kinds different, the effect of daily record
It is for daily record hash chain service, is mainly used for auditing verification nodes ' behavior, and account book refers to that verification node guarantee is consistent in system
The transaction account book of property, for recording transaction content.
In one embodiment of the invention, above-mentioned method of commerce contains the plan audited to verification nodes ' behavior
Slightly, the implementation of the audit strategy need to rely on the daily record hash chain of node itself, and specific embodiment is as follows：
All verification nodes are respectively provided with the daily record hash chain of itself in system, and the content in the daily record includes " Query（Request）”、
“Commit（Confirm）" two kinds.“Query（Request）" refer to that node receives transaction request after, for user in transaction content
Digital signature, whether honeysuckle is verified for input, with Query's (node, tx, input, timestamp) after being verified
Form is logged by, and node refers to current authentication node ID, and tx is transaction cryptographic Hash, and input is that verification node verification passes through
Transaction input, timestamp is current time stamp.What the chain header value of current log hash chain can be recorded with this Query adds
Enter and change, h_n=H (Query ‖ h_ (n-1)), h_n refers to the hash chain header value after nth bar record in formula, and Query, which refers to, to be worked as
Preceding record, h_ (n-1) in a few days in will preceding n-1 bars hash chain header value.The hash chain header value of current log by signature () form be transferred to transaction Commit（Confirm）Verify node, σ is numeral in formula
Signature, pk is sends the public key of information node, and tx is transaction cryptographic Hash, and input is that the transaction that node verification passes through inputs, node
Refer to node ID, h is current chain header value, and n is corresponding records series number.Merchandise " Commit（Confirm）" node receive it is foregoing
After the signature that each node is sent, these signatures can be verified（Including input, node ID, daily record included in signature
Chain header value etc.）, can be logged by after being proved to be successful in the form of Commit (node, tx, signs, timestamp), node
Refer to present node sequence number, tx is transaction cryptographic Hash, and signs is the received all signatures of node, and timestamp is current time
Stamp.The chain header value of current log hash chain can change with the addition that this Commit is recorded, h_m=H (Commit ‖ h_
(m-1)), h_m refers to the hash chain header value after the m articles record in formula, and Commit refers to current record, h_ (m-1) in a few days preceding m- in will
The hash chain header value of 1.
And so on, i.e., in whole block catenary system, all nodes are directed to Query the and Commit behaviors of a transaction
Will be not only by self record, but all nodes in system can be broadcast to, and be recorded at the same time in the daily record of these nodes,
Form between system interior nodes the network of cross validation immediately, when a certain node want to distort record or not as when, should
The daily record of node can expose its cheating, ensure the normal operation of whole system.
As shown in figure 4, each node has the daily record hash chain of its own, its row in agreement of knowing together is recorded
For, including Query（Request）And Commit（Confirm）Behavior.For example, when client submits a new transaction tx to node 1-3
When, it can be recorded in after anti-honeysuckle is verified in the form of Query in daily record, and by current chain header value（hn）With signature
Form sends client to；Client is collected into the signature more than half（Signs, it is current comprising each verifier in signature
Chain header value as witness）Afterwards, these are signed to send to node 4-6 together with transaction and is traded verification；Transaction verification passes through
Afterwards, all signs that node 4-6 can send client are recorded in daily record in the form of Commit, and generate one it is new
Chain header value（hm）.
After introducing daily record hash chain, for " request " during same transaction, " confirmation " two stage behaviors it is mutual
Record and verification so that any node is practised fraud and can be found not as behavior in the visible daily record of the whole network.
In addition, the method for commerce based on block chain network of the present invention can be realized by way of code.The code
It is storable in various computer-readable storage mediums（Including but not limited to disk, tape, CD, hard disk, USB flash disk, SD card and memory bar
