Embodiment Construction

[0037] figure 1 An example of a blockchain network 100 is shown according to some embodiments. As shown, blockchain network 100 may include one or more client devices (eg, Node A, Node B, etc.) coupled to blockchain system 112 . Client devices may include light nodes. Instead of downloading the full blockchain, light nodes can only download block headers to verify the authenticity of blockchain transactions. Light nodes can be served by full nodes (eg, nodes in blockchain system 112 ) and effectively rely on full nodes to access more functionality of the blockchain. Light nodes can be implemented in electronic devices such as laptops, mobile phones, etc. by installing appropriate software.

[0038] The blockchain system 112 may include multiple blockchain nodes (eg, node 1, node 2, node 3, node 4, node i, etc.), which may include full nodes. Full nodes can download every block and blockchain transaction and check them against the blockchain's consensus rules. Blockchain n...

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for implementing blockchain contracts are provided. One of the methods includes: obtaining bytecode of ablockchain contract, wherein the bytecode comprises an indicator indicating a type of the blockchain contract; determining a virtual machine corresponding to the type based at least on the indicator;and triggering the determined virtual machine to execute the blockchain contract.

Description

technical field [0001] The present application generally relates to methods and apparatus for implementing different types of blockchain contracts. Background technique [0002] Blockchain provides data storage in a decentralized manner by keeping data in a series of data blocks that have a sequential relationship with each other. The blockchain is maintained and updated by a network of nodes that also validate data. More recently, blockchains have been extended to provide a framework for executing blockchain contracts (eg, smart contracts) that include terms of contracts between users written in lines of code. A blockchain contract can be a computer protocol designed to digitally facilitate, verify or enforce the negotiation or performance of a contract. To process blockchain contracts, each node of the blockchain network runs a corresponding virtual machine (VM) and executes the same instructions. A VM is a software emulation of a computer system based on a computer arc...
