Problems solved by technology

[0005] The machine code length of the Ethereum virtual machine is designed to be 256 bits, which leads to the inefficiency of some conventional integer operations.
[0006] 2. Stack overflow
[0007] The call depth of the Ethereum virtual machine is limited to 1024. If this limit is exceeded, a stack overflow error will be triggered
[0008] 3. Cannot be upgraded
[0009] According to the design of the Ethereum smart contract platform, once a smart contract is created, it cannot be modified. In enterprise applications, business iterative upgrades are the most basic requirements. This feature limits the application of EVM in enterprise scenarios
[0010] 4. Data privacy issues
The Docker solution relies heavily on third parties, making it difficult to deploy and expand

Abstract

The invention relates to a method and a system for constructing an intelligent contract in a block chain. The method comprises the steps of 1, constructing an intelligent contract core system in the block chain; Step 2, contract upgrading based on the intelligent contract core system; Step 3, contract execution based on the intelligent contract core system; And step 4, performing data privacy protection based on the intelligent contract core system. The characteristics of data isolation, contract upgradable and data privacy protection are provided, and the requirements of enterprise organizations for service iterative upgrade, data governance and data security are better met.

Description

technical field [0001] The invention belongs to the field of block chains, and in particular relates to a method and system for constructing smart contracts in block chains. Background technique [0002] A "smart contract" is a computer protocol designed to communicate, verify or enforce contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. The concept of smart contracts was first proposed by Nick Szabo in 1994. It was not until the birth of Bitcoin that people discovered that the underlying blockchain technology of Bitcoin was inherently able to provide a trusted execution environment for smart contracts. Smart contracts have become a blockchain 2.0 important feature of the era. [0003] The Ethereum platform took the lead in developing a smart contract platform to support the operation of smart contracts. Contract developers can use Turing-complete high-level languages ​​such as S...
