区块链、人工智能、数字孪生、人机交互、物联网等面向数据的新一代信息技术的演进并非偶然，而是从Web2.0向Web3.0演进的技术准备。从技术上来看，元宇宙是基于Web3.0技术体系和运作机制支撑下的可信数字化价值交互网络，是以区块链为核心的Web3.0数字新生态。他总结道，元宇宙是以区块链为核心的Web3.0技术体系支撑下的新场景、新产业和新生态，将会在数字环境下催生大量创新商业模式，形成数字空间新范式。
区块链是Web3.0和元宇宙实现的技术基础之一，当前的互联网只能实现信息的传递，尚不能实现价值的流转，而Web3.0能真正实现“价值的连接”。这种价值的流转也成为元宇宙实现的基础。
The technical cost of blockchain alliance chain development is very high,and compared to traditional software development,it requires the use of more low-level technologies and algorithms.The underlying foundation of blockchain technology is cryptography and consensus algorithms,which require professional technical support.Of course,there are also many open source blockchain platforms available for enterprises to use,such as Hyperledger Fabric,Corda,and so on.If enterprises choose to use these open source platforms for development,it can reduce technical costs,but it also requires in-depth understanding and customized development of open source platforms.
For large enterprises,they may need to rely on cloud services or professional blockchain service providers for development.These service providers include AWS,Azure,Google Cloud,IBM,and others,providing a complete set of solutions including blockchain nodes,storage,programming interfaces,and more.The fees required for these cloud services will increase with the scale and duration of the services.
Blockchain is a data structure that utilizes cryptography to ensure data security,transparency,and decentralization.Each node can store its complete copy,ensuring data integrity and tamper resistance.Through blockchain technology,it is possible to remove centralized trust mechanisms and build a secure,efficient,and trusted distributed system.
2.Characteristics of blockchain
Blockchain technology has the following main characteristics:
(1)Decentralization:The blockchain technology adopts a decentralized architecture,without single point of failure,which improves the security and reliability of data.
(2)Anti counterfeiting:The encryption algorithm of blockchain technology ensures the immutability of data.
(3)Transparency:The decentralization of blockchain technology allows data to be replicated by numerous nodes,allowing anyone to view it at any time.
(4)Smart contracts:Blockchain technology's smart contracts enable automatic execution of intermediaries and automatic resolution of repayment or payment protocols.
