Detailed explanation of the technical basis of Web3.0 (development trend and application prospect)

I. Definition and Characteristics of Web3.0

Web3.0, also known as the third-generation Internet, is an improvement and evolution of Web2.0. Its core features include decentralization, blockchain technology, smart contracts, and an emphasis on data privacy and security. Unlike Web2.0, Web3.0 aims to achieve a more open, transparent, and secure network environment through a decentralized approach, allowing users to have greater control over their own data and digital identities.

II. Technical Foundations of Web3.0

Web3.0 is built on several key technological foundations. The following are detailed introductions to these core technologies:

1. Distributed Computing

• Principles and Features: Distributed computing aims to break down a large computing task into multiple smaller tasks and then distribute them to numerous nodes in the network for parallel processing. These nodes can be various devices with computing capabilities, such as ordinary personal computers, servers, etc. They achieve interconnection and collaborative computing through the network. For example, the famous distributed computing project "Berkeley Open Infrastructure for Network Computing (BOINC)" enables volunteers from all over the world to utilize their idle computer computing power to participate in various scientific computing projects, such as searching for signals of extraterrestrial life and climate simulation. It has a strong fault tolerance ability. Even if some nodes fail, as long as there are enough normal nodes left in the network, the entire computing task can continue to be completed. Meanwhile, it has excellent scalability. As more nodes join, the computing capacity of the entire system will increase accordingly, enabling it to easily handle increasingly large and complex data processing requirements.

• Role in Web3.0: It has changed the situation of excessive concentration of computing resources in the Web2.0 era and provides more flexible, efficient, and reliable computing support for Web3.0 applications. For example, in decentralized social platform applications, a large number of users' real-time information interaction, content recommendation algorithms, and other computing tasks can be distributed to numerous nodes for processing through distributed computing, avoiding application lagging and other issues caused by single-point computing resource bottlenecks and ensuring the smooth operation of the application.

2. Distributed Data Storage

• Principles and Features: Different from the centralized storage in traditional Web2.0, distributed data storage adopts a decentralized approach, cutting data into several small pieces and dispersing them among numerous different nodes. These nodes together form a huge storage network. For example, the InterPlanetary File System (IPFS) works based on content addressing. After each file is split into small pieces, each node stores different data fragments and corresponding index information. Through these indexes, the complete file can be reassembled. This storage method naturally has high redundancy, and data is less likely to be lost due to single-point failures. Multiple copies are distributed on different nodes, greatly improving data security. Moreover, it breaks data silos. Different applications and platforms can obtain the required data in this distributed storage network as long as they follow the corresponding protocols, realizing efficient sharing and circulation of data.

• Role in Web3.0: It gives users stronger control over their own data, enabling them to independently decide on the sharing objects and usage permissions of the data. For example, on a Web3.0 digital content creation platform, the works uploaded by creators are stored in the distributed network. The platform cannot use or tamper with the works' data at will. Only with the authorization of the creators can other users or applications access the relevant data, ensuring the privacy and security of the data. At the same time, it also promotes the full utilization of data in the entire Web3.0 ecosystem and maximizes the value of the data.

3. Blockchain Technology

• Principles and Features: Blockchain is essentially a distributed ledger technology, consisting of a series of blocks connected in chronological order. Each block records data content such as transaction information that occurred within a certain period of time. These blocks are linked through technologies such as hash functions in cryptography, forming an unalterable chain. The entire ledger is jointly maintained by numerous nodes in the network, and there is no centralized authority to control the whole situation. Taking the Ethereum blockchain as an example, numerous developers can create smart contracts and decentralized applications (DApps) on its platform. Every transaction and the execution of each contract will be recorded on the blockchain and verified and confirmed by multiple nodes in the network to ensure the authenticity and immutability of the information. Meanwhile, blockchain adopts asymmetric encryption technology. The public key is used to receive information and verify signatures, while the private key is used to encrypt information and perform signature operations, further ensuring the security of user identities and data transmission.

• Role in Web3.0: It is a key support for the decentralization feature of Web3.0, ensuring that various interactions, transactions, and other activities in the network can be carried out in a trustworthy and transparent environment. For example, in the field of decentralized finance (DeFi), lending, trading, and other financial behaviors are all realized based on blockchain. Without the intervention of traditional centralized institutions like banks, users can still participate with confidence because all transaction records and capital flows are clearly recorded on the blockchain, which is unalterable and publicly transparent, safeguarding the rights and interests of all parties and building a new financial trust system. Meanwhile, in terms of the issuance and management of digital assets, blockchain also plays a core role in determining the ownership and transfer records of digital assets and promoting the further development of the digital economy.

4. Smart Contracts

• Principles and Features: A smart contract is an automatically executable contract clause based on blockchain technology and deployed on the blockchain in the form of code. It stipulates the rights and obligations of the participating parties under specific conditions. When the preset conditions are triggered, the contract will automatically execute the corresponding operations without human intervention and is not affected by any centralized institution. For example, in a blockchain-based housing rental smart contract, when the tenant pays the rent to the designated blockchain account as agreed (through a cryptocurrency payment or other methods that meet the requirements of the blockchain), the smart contract will automatically verify the payment situation. Once the payment is confirmed to be successful, it will send the electronic key and other access permissions of the house to the tenant and simultaneously notify the landlord that the rent has been received. The whole process is efficient, transparent, and accurate. Smart contracts have certainty. As long as the same conditions are input, the same results will be obtained regardless of which node they are executed on, and they have the characteristic of immutability. Once deployed on the blockchain, their code and execution logic are very difficult to change, ensuring the fairness and stability of contract execution.

• Role in Web3.0: It greatly improves the efficiency and trustworthiness of various transactions, cooperation, and other activities. In the supply chain management scenario of Web3.0, upstream and downstream enterprises can stipulate terms such as goods delivery and payment for goods through smart contracts. When the transportation status of the goods meets the acceptance standards stipulated in the contract (for example, judged by the location and status information of the goods uploaded by Internet of Things devices), the smart contract will automatically execute the payment process, reducing traditional cumbersome processes such as manual reconciliation and auditing, accelerating the operation speed of the supply chain, and avoiding default risks and other issues caused by human factors, thus promoting more efficient and safe cooperation among different entities in the Web3.0 ecosystem.

In addition, the technological foundations of Web3.0 also involve the integration and application of cryptographic technologies such as zero-knowledge proofs and homomorphic encryption, as well as related technologies such as the Internet of Things and artificial intelligence. These technologies jointly help Web3.0 build a more decentralized, secure, efficient, and innovative Internet ecosystem.
