Smart contracts
Smart contracts are one of the core components of the blockchain public chain and an important carrier for public chain applications.Smart contracts are programmable scripts that can automatically execute protocols,rules,and conditions.Through smart contracts,various complex business functions on the public chain can be implemented.During the development process,it is necessary to write reasonable smart contracts and consider the security,efficiency,and other aspects of smart contracts.
Consensus mechanism
The blockchain public chain adopts a consensus mechanism to ensure the security and stability of the blockchain.Consensus mechanism refers to the process in which all nodes achieve consensus through consensus and verification.
Standardize the interconnection and interoperability between blockchain systems and between blockchain systems and external systems.Mainly including application program interfaces,data formats,cross chain standards,etc.
(1)Application Program Interface Standards
Used to guide the data transmission and message exchange between the underlying blockchain platform and the upper level application programs,providing a basis and support for the development of application program interfaces based on the blockchain platform.
(2)Data format standards
It is used to standardize the data format of the blockchain system,provide consistent and compatible data formats for different blockchain systems,and improve the ability of data exchange and interoperability between different blockchain systems.
(3)Cross chain standards
It is used to standardize the data and value exchange methods between blockchains,and formulate the definition,format,technical requirements and other standards of cross chain and interoperability protocols between isomorphic or heterogeneous blockchains.
Application Program Interface Standards.By sorting out the distributed application interface rules,interface types,invocation methods,parameter requirements,and access modes related to mainstream blockchain platforms,propose application interface methods and requirements that are compatible with mainstream platforms,providing support for application development.
Data format standards.By studying existing mainstream blockchain systems,provide requirements for blockchain data classification,data structure,and data object format,and clarify relevant attributes such as data identification,name,type,length,and description.
Cross chain standards.By giving the message type,data format,communication protocol,service flow,verification method and other contents of the interaction between isomorphic or heterogeneous blockchains,the technical framework of cross chain and interoperability is established to strengthen the interconnection between blockchains.
