The type of code to be converted (i.e. targeted code type), the modeling after can thus be provide the data needed.
S2 is modeled according to the type of intelligent contract code and targeted code type to generate abstraction interface and mode.
Specifically, some abstraction interfaces and object are produced according to the type of intelligent contract code and targeted code type,
Service is provided for code conversion later.
S3 parses intelligent contract code, and the service code of intelligent contract code and characteristic of speech sounds are divided
From.
Wherein, service code includes source code and bytecode
Specifically, by code dehind technology, code analysis, the business of intelligent contract code are carried out to intelligent contract code
Code and characteristic of speech sounds are separated, and purpose is exactly that this most complicated problem becomes two relatively solely by code analysis
It is vertical, simple question: syntactic definition and syntax tree parsing.
S4 parses characteristic of speech sounds in the way of symbol resolution, to obtain the syntax tree of intelligent contract code.
Specifically, characteristic of speech sounds is parsed in the way of symbol resolution, comprising: parse the institute in characteristic of speech sounds
There is token, token includes variable, function name, packet title, keyword, operator.
Specifically, replacing traditional syntax tree analysis mode using symbol resolution mode, which can be incited somebody to action
All token (i.e. token) regard symbol as, and symbol can be with eval, and can also be one with not eval, symbol can represent change
All names for occurring thing in code such as amount, function name, packet title, keyword, operator, this be abstracted greatly simplify
Parsing difficulty of the different language to syntax tree.
The syntax tree of intelligent contract code is converted into target grammer tree code using code conversion frame by S5, and according to
The object code of target grammer tree code, service code and abstraction interface and schema creation intelligence contract.
Specifically, according to the mesh of target grammer tree code, service code and abstraction interface and schema creation intelligence contract
Mark code, comprising: service code is inherited and realized abstraction interface and mode；By the business after target grammer tree code and processing
Code combines, and generates the object code of intelligent contract.
Specifically, the syntax tree parsed is carried out reflecting for corresponding characteristic of speech sounds using existing code conversion frame
It penetrates, is converted into wanting the syntax tree (i.e. target grammer tree code) of transfer language, while service code is inherited and being realized modeling mould
The abstraction interface and mode of block creation finally combine the service code after target grammer tree code and processing, generate intelligence and close
Object code about.
S6 exports the object code of intelligent contract.
Wherein, the object code of intelligent contract is exported in the form of character string.
Specifically, the object code of the intelligent contract of above-mentioned generation can be handled, intelligence is exported in the form of character string
The object code of energy contract, and can return to client, to use.
The intelligent contract processing method of the embodiment of the present invention, passes through existing or independent development language codes transfer framework
For technological means, the intelligent contract code for realizing any block chain is all convertible into targeted code type, to solve not
With block chain intelligence contract across the language compatibility of seamless migration, contract and reduce contract development cost the problem of.

It is separated with characteristic of speech sounds.
Wherein, service code may include source code and bytecode.
Specifically, code analysis module 130 carries out code analysis, intelligence to intelligent contract code by code dehind technology
The service code and characteristic of speech sounds of energy contract code are separated, and purpose is exactly that the problem that this is most complicated by code analysis becomes
At two relatively independent, simple questions: syntactic definition and syntax tree parsing.
Symbol resolution module 140 is for parsing characteristic of speech sounds in the way of symbol resolution, to obtain intelligent conjunction
The about syntax tree of code.
Wherein, symbol resolution module 140 is specifically used for: parse all tokens in characteristic of speech sounds, token include variable,
Function name, packet title, keyword, operator.
Specifically, symbol resolution module 140 replaces traditional syntax tree analysis mode, the symbol using symbol resolution mode
All token (i.e. token) can be regarded as symbol by number analysis mode, and symbol can also be with not eval, symbol with eval
One can represent all names for occurring thing in code such as variable, function name, packet title, keyword, operator, this
Kind is abstract to enormously simplify different language to the parsing difficulty of syntax tree.
Code conversion module 150 is used to that the syntax tree of intelligent contract code to be converted into target language using code conversion frame
Method tree code, and according to the target generation of target grammer tree code, service code and abstraction interface and schema creation intelligence contract
Code.
Wherein, code conversion module 150 is raw according to target grammer tree code, service code and abstraction interface and mode
At intelligent contract object code when, be specifically used for: service code inherited and realized abstraction interface and mode；By target grammer
Service code after tree code and processing combines, and generates the object code of intelligent contract.
Specifically, code conversion module 150 is carried out the syntax tree parsed pair using existing code conversion frame
The mapping for answering characteristic of speech sounds, is converted into wanting the syntax tree (i.e. target grammer tree code) of transfer language, at the same by service code after
The abstraction interface and mode of modeling module creation are held and realize, finally by the service code knot after target grammer tree code and processing
It closes, generates the object code of intelligent contract.
Code output module 160 is used to export the object code of intelligent contract.
Wherein, the object code of intelligent contract is exported in the form of character string.
Specifically, code output module 160 can be handled the object code of the intelligent contract of above-mentioned generation, with character
The form of string exports the object code of intelligent contract, and can return to client, to use.
In conclusion the intelligent contract processing unit of the embodiment of the present invention, passes through existing or independent development language generation
Code transfer framework is technological means, and the intelligent contract code for realizing any block chain is all convertible into targeted code type, from
And it solves across the language compatibility of seamless migration, contract of different blocks chain intelligence contract and reduces asking for contract development cost
Topic.
