FISCO BCOS supports implementing smart contracts in several ways

• SolidityThe contract programming language used in the Ethereum ecosystem, FISCO BCOS expands a series of functions for the alliance chain, and is the most commonly used way to develop smart contracts on FISCO BCOS。

• Pre-Compiled Contract: Built-in customized smart contracts directly inside blockchain nodes, using c++Language implementation, can directly call the node internal various interfaces, for complex scenarios, the use of high barriers to entry。

• WBC-LiquidThe Rust-based smart contract programming language developed by the micro-blockchain, with the help of Rust language features, can achieve more powerful programming functions than the Solidity language。

Contract Development of Solidity Language on FISCO BCOS

• Basic

  • The syntax is the same as that of Ethereum, please refer to Solidity official documentcarry on learning。

• For Alliance Chain Expansion

  • Write Solidity code to call the built-in contract interfaceCRUD contract, KVTable contract, group ring signature, system management, etc

Important

Solidity has some built-in cryptographic algorithms (such as keccak256 / sha3, etc.). When the deployed FISCO BCOS block is of the state secret type, the corresponding state secret algorithm (such as sm3, etc.)
