What is Web3.0?
Web3.0 is a decentralized Internet, aiming at creating a brand-new contract system and subverting the way individuals and organizations reach agreements. Therefore, digital identity authentication, privacy protection, data confirmation and decentralization are the keys to its development. This has a natural fit with blockchain technology, and it is also one of the reasons why blockchain is called value Internet. Web3.0 applications either run on blockchain, a decentralized network composed of many peer-to-peer nodes (servers), or a combination of the two to form an encrypted economic protocol. These applications are often referred to as dapps (Decentralized Applications), which is often used in the Web3 field.
The development history of the Internet: Web1.0 → Web2.0 → Web3.0
Web1.0 is the first development stage of the Internet. All Internet services are based on open protocols and controlled by communities. Web1.0 is mainly static HTML pages. People get information from the Internet, but most of this information is just for reading. So large Internet companies like Yahoo, Google, Amazon, Facebook, YouTube and so on came into being.
Web2.0 is from the mid-2000s to the present. At that time, due to the development of the Internet in terms of network speed, optical fibre infrastructure and search engine, users’ demand for social networking, music, video sharing and payment transactions has greatly increased. Web2.0 is also called a social network, and the way we surf the Internet now is what Web2.0 looks like. At present, the most popular short video platform is the typical representative of Web2.0. People can transmit their ideas by personal live broadcast, and users can communicate online in various ways such as praise, comment and interaction.
Even though this new interactive Internet experience brings many new functions to users and improves the user experience. But the problem followed, and it has not been completely solved until today.
Disadvantage 1:
Web2.0 data is stored in the central server, and there is a potential safety hazard. Web2.0 is managed by a central server, and user data is stored and managed centrally on the servers of large companies trusted by users. Data on servers are protected by firewalls, and system administrators are required to manage these servers and firewalls. If there is a successful hacker intrusion or some force majeure factors, it is likely to cause data loss and bring significant losses to customers.
Disadvantages 2:
Web2.0 users’ privacy is not guaranteed. Nowadays, we are living in an interconnected era. More and more devices, such as mobile phones, smart watches and cars, collect our information all the time and then connect with the Internet to store our information in the cloud server. Of course, this is also a problem that must be faced in the era of big data.
Disadvantages 3:
Web2.0 needs to rely on a big platform to build trust. Web2.0 has brought infinite convenience to our life, but it needs to be built on a platform with credibility. Although it is convenient for our life, middlemen have huge profit margins, and profits often come from users, but users don’t get enough returns in this process.
Benefits of Web3.0
Then, based on Web2.0, Web3.0 can effectively solve these shortcomings of Web 2.0, so that the value of the Internet ultimately belongs to users, and blockchain technology is the driving force of Web3.0.
Web3.0 is a network composed of several independent nodes. Even if one or two nodes are compromised by hackers and the blockchain network collapses, there are thousands of nodes that store safe and effective data and can still run normally. Secondly, the decentralized network completely eliminates middlemen, and there is no need to trust any company or any third party. In the Web3.0 world, code is the law, and you only need to believe in the mathematical and computational principles of blockchain construction. Blockchain has also brought a new economic model for Web3.0. No longer companies with centralized servers, such as Google, Google, Facebook and Amazon. Blockchain gives value to the network itself and the community members connected with the network through the pass card. Finally, there is no need to store a large amount of data on servers in the future, and it will be easier and cheaper to deploy new servers.
Decentralization mode can be applied to any part of the network ecosystem, including virtual host and storage, domain name system, applications and search functions. For example, decentralized storage has been the top priority in the field of encryption for a long time. Users store data in the same way as using Dropbox or GoogleDrive today, but there is actually a distributed network in the back end, where data is stored. Interestingly, anyone can become a storage provider and contribute storage space to the network.
In this case, it will be more difficult for any centralized organization to stop or control the information flow on the Internet. Any agent that wants to mine and analyze user data will no longer have a single source to mine, but need to retrieve data from millions of potential storage locations–and filter them one by one through IP packets. With this, Web 3.0 will change the imbalance of rights caused by the current centralized network, and return the power of information release to individuals. This is the original idea of the Internet by Internet pioneers.
In short, Web3.0 can provide services more safely and efficiently, while protecting our personal privacy from being threatened. At present, Web3.0 has not been widely popularized. With the continuous development of blockchain applications, Web3.0 will gradually integrate into our lives in the future, bringing us a more comfortable and secure Internet environment.
