Embodiment 2

[0064] refer to figure 2 As shown, a contract execution method based on the smart contract engine system provided by the embodiment of this specification, if the contract to be executed is only a native smart contract, it will be executed through the following steps:

[0065] S1. Make the native smart contract meet the interface requirements of the Ethereum Virtual Machine (EVM) smart contract system;

[0066] S2. Obtain the contract content according to the contract address registered in the native smart contract, and call the exec execution interface, which can execute the functional logic of the contract according to the function signature;

[0067] S3. The above native smart contract is compiled by the native compiler to generate executable code of the target machine, execute it on the machine, and call the blockchain data through the blockchain access interface layer;

[0068] If the contract to be executed is an Ethereum Virtual Machine (EVM) smart contract, the smart ...

Embodiment 3

[0074] The embodiment of this specification provides a contract execution method based on the smart contract engine system, including:

[0075] S1. The user writes a native smart contract using the blockchain system language, and the upper layer of the native smart contract meets the interface requirements of the Ethereum Virtual Machine (EVM) smart contract system;

[0076] S2. Obtain the contract content according to the contract address registered in the native smart contract, and call the exec execution interface, which can execute the functional logic of the contract according to the function signature;

[0077] S3. The above native smart contract is invoked by the blockchain access interface layer, compiled by a native compiler to generate machine executable code, and executed on the machine.

[0078] Further optionally, in the step S1, the user uses the native smart contract written by the blockchain system language, including the definition of the contract structure, t...

Abstract

The invention discloses an intelligent contract engine system based on a block chain and a contract execution method. The intelligent contract engine system based on a block chain includes a user interface layer, an intelligent contract system layer and a block chain access interface layer; the user interface layer is used for providing a unified interface to users, and through the unified interface, the users can interact with an intelligent contract in the intelligent contract system layer in an identical data interaction manner; the intelligent contract system layer is used for executing the intelligent contract; and the block chain access interface layer is used for providing a unified interface for accessing block chain data for the intelligent contract in the intelligent contract system layer. The intelligent contract engine system based on a block chain can overcome the defects of restricted performance due to slow execution speed and restricted expandability due to limited expression ability caused by adoption of an EVM mode in an existing contract engine system; and at the same time, the system can also overcome the defect that the overall efficiency is affected due to long starting time caused by adoption of a Docker mode.

Description

technical field [0001] The invention belongs to the field of computer data processing and calculation, and in particular relates to a blockchain-based smart contract engine system and a contract execution method thereof. Background technique [0002] The concept of "smart contract" was first proposed by cryptographer Nick Szabo in 1994. It is essentially an automatic contract, similar to an if-then statement in computer programming. When a pre-programmed condition When triggered, the smart contract can automatically execute the corresponding contract terms. The more common application of smart contracts is in the financial field. Almost every type of financial contract can be written as a smart contract in the form of program code. [0003] After the concept of "smart contract" was proposed, no good practical method was found until the emergence of blockchain. The blockchain 2.0 era is defined as "blockchain + smart contract", which shows the importance of smart contracts ...
