Description
Technical field
The present invention relates to a kind of intelligent contract technical fields, execute and storage more particularly to contract intelligent on block chain
Systematical design idea method.
Background technique
Contract is the basis of economic activity in society, it is two aspects or several respects in common cooperation, in order to true
The provision abided by jointly determining respective rights and duties and concluding.Contract defines target, content, time and the execution of transaction
Agreement etc., and there is legal assurance, both sides or promise of meeting one's engagements in the state of trust or distrust in many ways, there is method can
According to, have according to can seek.Contract is by normative commitment and executes contract process, to guarantee the orderly progress of transaction.Currently, people
Class society develops to digital society, and virtual economy is the key activities of digital society, and a huge challenge is exactly will be real
Middle people's economic activity is transferred to network virtual in the world.The concept of intelligent contract was mentioned in 1994 by Nick Szabo for the first time
Out.Intelligent contract is the computable trade agreement program code that can execute agreement terms automatically, it and block chain
(Blockchain) combination of technology forms the digital contract of value Transfer or code i.e. contract (Code as on sincere network
A Contract), just becoming the important means that people maintain secure digital relationship in virtual world, is being future digital society
Basic agreement, therefore the correlative study of intelligent contract is of great significance.
Intelligent Contract Theory almost occurs with Internet technology (World Wide Web) simultaneously, but application practice is always
Theory is seriously lagged behind, is lacked the clear path of this theory transformation reality.Two aspect problems are mainly faced, first is that intelligence
Energy contract does not have effective means to control physical assets, guarantees the execution of contract, as commodity by being stored in by vending machine
Internal control property right, but computer program is difficult to control the assets in the real world such as cash, share；Second is that single
Computer is it is difficult to ensure that execute these clauses to obtain the trust of contract side, contract side needs reliable explanation and executes code
Trusted context, it can not check problematic computer in person, also can not directly observe and move with the execution for verifying other contract sides
Make, third party is only allowed to audit the record that each side's contract executes.And the appearance of block chain technology solves these problems, establishes
The basis of intelligent contract application, meanwhile, the application range of block chain has also been enlarged in intelligent contract.Block chain is fully digitalization money
The record of production and transfer are laid a good foundation, and by the assets of fully digitalization, block chain is directly controlled to computer code offer
The method of assets, so that intelligent contract has implementation capacity.On block chain, the control of assets is exactly to control the corresponding key of assets
Permission, rather than any material object.Block chain makes computing system become trust system, it has been not limited only to the function of database
Can, while still can execute code and record the distributed computer of digital asset ownership, digital asset ownership can
To be uploaded and be stored in block chain, and according to instruction execution, once block chained record contract code, contract side
Determine that contract will not be modified.2015 ether mill (Ethereum) block chain technology and intelligent Contract Theory are combined, design
Programmable contract language and executable infrastructure are realized, the huge applications based on contract intelligent on block chain have been started
Scene.In Ethereum, intelligent contract is stored in the script on block chain, in a distributed fashion by block chain node
It executes, is equivalent to the executor of law during business transaction, supervision and management, regulation.Block chain with sequentially, safely, can verify that
Mode guarantee the execution of contract.The behavior of lending for being related to user, car dealer and bank and formality compared to current complexity,
Intelligent contract is the computer program that can execute agreement terms automatically, it can improve existing business model, prior
It is that they may overturn existing business model, also greatly reduces the expense of third party intermediary.
But the existing intelligent contract technology based on block chain still has many problems not have also also in a primary stage
There is solution, if execution efficiency is low, although Ethereum improves the publicly-owned chain algorithm of bit coin, it also requires 15 seconds/block, this
Also it is unable to satisfy the demand of actual production；The safety problem that intelligent contract is executed as code on the chain of block chain；And intelligence
Contract code and the consistency problem of text etc..Still have currently based on the design of the intelligent contract of block chain with technology and further grinds
Study carefully and improved space, it is necessary to further intelligent contract technology of the research based on block chain.
The combination of block chain and intelligent contract is included in the speed of transaction to block chain and the scalability of intelligent contract all can
It has an impact.The intelligent contract of current Ethereum, which executes model, reduces the speed that block chain is included in transaction.
Intelligent contract is exactly one section of code by negotiating, its execution should be distributed, observable and can verify that
, code is deployed on sharing, duplication account book, it can maintain the state of oneself, the assets that draw oneself up (state,
Assets are stored on account book as code), additionally it is possible to the external information received is responded.Intelligence contract is put
Execute on block chain is exactly the consistency for guaranteeing contract implementing result using the consistency algorithm that block chain itself carries.
Fig. 1 is the principle schematic diagram of intelligent contract Yu block chain combination, wherein block chain is safe distributed data
Library, intelligent contract promote the execution of contract with uniformity with user interface by agreement, observability, verifiability, improve oneself
Property processed and access control.Code/program is stored in the form of text on different nodes, adds breakpoint to code/program, and right
The program state of breakpoint carries out consistency checking, can only pass through the information space of message alteration program, contract and its state recording
In block chain, the change of contract state intelligently passes through message and goes to trigger.

Specific embodiment
Ethereum is the first system that distributed virtual machine is combined with block chain, intelligent contract on privately owned block chain
The design of asynchronous execution model intelligent Contract Design in Ethereum.The block chain of Ethereum not only stores friendship
Easily, newest account status information is also stored, account is divided into two kinds: one is contract accounts, and wherein contract account just has accordingly
Code, one is external account, this account does not have code.Each account has corresponding address, includes: nonce (account
In nonce be the equal of the number of deals done the account, the nonce of account is denoted as), balance (account balance is denoted as),
Contract code (contract account just has, and is denoted as) and storage (being denoted as).Contract code is stored in contract account, and contract is to need to hand over
Easily triggering executes, and the address of contract account is filled in transaction, and such calculate node will go inquiry to correspond to after receiving transaction
Code, in addition data information in transaction is as input to execute contract.Transaction includes following element: nonce is (in transaction
Nonce is the equal of processed mark of trading, and is denoted as), gasPrice (since Ethereum is publicly-owned chain, need to pass through receipts
Take calculating expense not attacked to protect, be denoted as), gasLimit (calculating the upper limit of expense, be denoted as) and to (reception of transaction
Side, is denoted as), value (amount of money is denoted as) and v, r, s is used for signature verification.
After Ethereum first calculates the All Activity in new block, state root is put into the head of block, calculates block
Behind head, then new block is broadcasted, the calculating time of contract is caused to be included in the Production Time of block, so
The speed of Ethereum is very slow, moreover, a possibility that publicly-owned chain store historical data rollback, so being difficult to accomplish block meter
Calculate the separation calculated with transaction.The block of privately owned chain provides block and calculates and trade what calculating separated with termination property immediately
Possibility,
The general introduction of intelligent contract asynchronous execution method on privately owned block chain is given below in the present embodiment.
Intelligent contract asynchronous execution is exactly under the premise of not influencing contract state consistency, by the calculating of contract from block
Calculating extract.Basic thinking: the block of privately owned chain has instantaneity, is exactly, Ethereum different from Ethereum
Due to the consistency of itself, may stateful rollback possibility, and the block being verified in privately owned chain be will not be by
Rollback, so, can allow block chain that all sources are correctly traded and all be put into block chain, transaction can with asynchronous process,
The result of processing is also stored in bearing-age tree, then the root of bearing-age tree is put into the head of block, block when knowing together,
Consistency check only is carried out to the current transaction being processed.Transaction executed by transaction processor, transaction processor from
Not processed transaction and execution are taken out in block chain database.
Fig. 2 is intelligent contract asynchronous execution model (the Smart Contract Asynchronous based on block chain
Model, SCAM), block chain node is responsible for entering the correct chain transaction in source in chain, so that the sequence solidification of transaction, is then handed over
Easy to handle device handles transaction by the sequence traded in block chain one by one, is all to trade when doing block every time to newest processing
State does consistency synchronization.Last state is indicated that state_height indicates that exchange processed is in block by three variables
Highly, state_tx expression serial number processed of trading, state_root indicate the root of last state tree).
Fig. 3 shows the implementation procedure of privately owned block chain in SCAM, and block chain is responsible for the fixation that will trade when doing block
Transaction is not handled in chain, only whether the source of verifying transaction is correct, but can know together to the stateful transaction of newest processing.Afterwards
Face transaction processor is responsible for the trading processing in block chain, and last state value is provided when calculating new block, i.e.,
These three variables of state_height, state_tx and state_root check these three variables when verifying block
Value.
Trade fair is broadcast to all calculate nodes, and node passes through compute_right (tx, height, time_
Interval it) calculates whether to have permission and calculates new block, the node having permission calculates new block, and at this moment node needs pass through
State=querystate () inquires last state to transaction processor, is broadcast to other calculating after calculating new block
Node.After calculate node receives new block, need transaction processor proofing state whether correct, block is verified, then extensively
Affirmative vote is broadcast, negative vote is otherwise sent.When the affirmative vote or negative vote quantity of the block that node receives are more than the 1/ of number of nodes
3, then synchronize calculating, and memory block.Privately owned block chain executes system packet in intelligent contract asynchronous execution model (SCAM)
