That is the first transactions requests 610, the second transactions requests 620 and third transactions requests 630.Assuming that endorsement policy mandates client 601
These three transactions requests are sent at least two Endorser nodes and carry out endorsement signature, for example, client 601 can be distinguished
The first transactions requests 610, the second transactions requests 620 and third transactions requests are respectively sent to Endorser node 602 and 603
630.First transactions requests 610, the second transactions requests 620 and third transactions requests 630 can be at least one intelligent contract phases
Association, such as these transactions requests are associated with the first, second, and third intelligent contract respectively, or all with single intelligence contract
(such as first intelligent contract) associated or the first transactions requests and the second transactions requests and the first intelligent contract are associated simultaneously
And third transactions requests are associated with the second intelligent contract, etc..At Endorser node 602, based on from client 601
Three transactions requests 610,620 and 630, simulation executes this at least one intelligence contract associated with these three transactions requests
And three readsets for generating simulation implementing result, and simulating implementing result close (corresponding respectively to three transactions requests) each other not
It is overlapped.Then, 602 pairs of simulation implementing results of Endorser node carry out endorsement signature, and the simulation of endorsed signature is held
Row result 640 is sent to client 601.The behaviour similar at Endorser node 602 is executed at Endorser node 603
Make.After client 601 receives the simulation implementing result 640 from Endorser node 602 and 603, client 601 will
Simulation implementing result 640 is encapsulated in an affairs 650, and sends the affairs 650 to Orderer node 404.Orderer section
Point 604 generates block 660 after collecting the affairs of certain amount (or time-out), and block 660 is then sent to submission section
Point 605.It submits node 605 to read the affairs 650 for including in block 660, is held based on the simulation in world state verifying affairs 650
Multiple readsets of row result 640 close, and are verified with the validity to affairs 650, and when it is effective for verifying affairs 650, benefit
Multiple with simulation implementing result 640 in affairs 650 write set and update world state.Verifying may include: verifying affairs
Whether the value of each key changes compared with the value of the corresponding key of world state in the conjunction of readset included in 650, if become
It is invalid that change, which then marks the affairs 650,.Verifying can also include: whether sender's signature of verifying affairs 650 is legal；Verify thing
Whether the endorsement signature and endorsement number of signatures of business 650 meet the requirement of Sign Policies.If node 605 is submitted to be verified
Affairs 650 in the block received then carry out the Pleistocene using multiple set of writing of the simulation implementing result 640 in affairs 650
Boundary's state.Compared with prior art, in example 600, due to batch processing transactions requests, make it possible to criticize in an affairs
Amount calls intelligent contract and signs, such as 2 Endorser nodes are completed the endorsement signature number needed for endorsing and subtracted from 6 times
It is less 2 times, verifying number needed for correspondingly completing the endorsement signature of verifying affairs is reduced to 2 times from 6 times, this significantly reduces
Resource needed for signature and verifying signature, while significantly improving the affairs handling capacity of block chain.
