Blockchain Smart Contract Management Learning

Blockchain Smart Contract Management Learning

Term DefinitionBlockchain is a distributed database technology in which multiple computers participate in "bookkeeping" and jointly maintain a complete distributed database. Smart Contract is a contract triggered on a blockchain system, defined in the form of code, and triggered by transactions on the blockchain. Ethereum is an open source blockchain platform that supports smart contracts, with the Ethereum Virtual Machine (EVM) at its core. Ethereum Virtual Machine (EVM) is a Turing-complete virtual machine used to execute smart contract code on Ethereum. Bytecode is a low-level code representation that can be executed directly by a virtual machine. High-level language is a programming language that is closer to human language, such as Solidity, which can be compiled into bytecode. Trusted Execution Environment (TEE) is a hardware security technology used to execute code and protect data in an isolated environment. Intel Software Guard Extensions (SGX) is a TEE technology provided by Intel that can create an encrypted area in memory called an "enclave". Managed Smart Contract refers to a regulated smart contract whose content and execution process are subject to certain restrictions. Smart Contract Management Rule Rules used to manage and regulate smart contracts, such as smart contract blacklists. Encryption A process of converting information into an unreadable format to protect its confidentiality. Symmetric Encryption A method of encryption that uses the same key for encryption and decryption. Asymmetric Encryption A method of encryption that uses different keys for encryption and decryption. Digital Envelope A method of encryption that combines symmetric and asymmetric encryption. Short Answer Questions

Answer

Blockchain is a distributed database technology with characteristics including decentralization, openness, transparency, and immutability.

The main difference between Ethereum and Bitcoin is that Ethereum is a programmable blockchain platform that supports smart contract functions, while Bitcoin is mainly used for digital currency transactions.

Smart contracts are self-executing contracts deployed on the blockchain, defined by code and automatically executed when specific conditions are met.

Enterprise-level blockchain platforms face two major technical challenges: privacy and performance.

Trusted Execution Environment (TEE) is a hardware security technology that improves the security of blockchain by executing code and protecting data in an isolated environment.

Traditional solutions can improve security, but data management is difficult and it is difficult to supervise contract content.

543X.COM proposed a smart contract management solution based on TEE, which realizes refined management of smart contracts by encrypting contract code, storing decryption keys, setting extraction permissions, etc.

Management rules can be independently generated and updated in real time by the regulator, such as dynamically generated and updated by smart contracts deployed on an independent supervision chain.

By setting the extraction permission of the decryption key, the extraction of the decryption key of the regulated contract is prohibited, thereby shielding the content and execution results of the regulated contract.

This solution not only protects the privacy of smart contracts, but also realizes the effective supervision of smart contracts, solving the problem that traditional solutions are difficult to supervise the content of contracts.
