What is the future Internet ‘Web 3.0’?
Before knowing Web 3.0, it is necessary to understand Web 1.0 and Web 2.0. Web 1.0 was launched around 1989. It had static-type content, photos, and text. Web 1.0 was one-way communication. But gradually it was upgraded. Internet access and speed both started to increase.
Then, around the beginning of 2000, Web 2.0 was developed. When platforms like Facebook, Google came, and the discussion of Web 2.0 progressed rapidly.
Web 2.0 means ‘two way’ communication. It can be a conversation between the user and the platform. In Web 2.0, what the user searches for goes to the platform or the company’s server and again the information reaches the user from that server.
Even now we are using web 2.0 internet. All the digital platforms we use are based on Web 2.0.
But the downside of Web 2.0 is privacy. In this, another party, person or company started getting our data. This created fear for the user’s privacy. Web 3.0 has started to be discussed after many debates and discussions around the world.
What is Web 3.0?
Web 3.0 is the beginning of a new era in the Internet world. Web 3.0 is sure to come in the future even though it is still in the development stage. Lately, many companies have started making applications that are required for Web 3.0. Especially Web 3.0 has prioritized user privacy.
It does not contain user data under the authority of any individual or organization. Thousands of computers store user data. To manipulate a single piece of data, thousands of computers must verify it. That is why more emphasis is placed on user ownership.
The main technology behind Web 3.0 is blockchain. Databases are decentralized in blockchain technology. Traditionally, databases are centralized or controlled by one entity. However, in blockchain technology, no data can be changed without the permission of the person concerned. In blockchain technology, data is stored in a distributed manner, where there are different nodes, servers or computers.
When trying to make a change in content, other nodes should also be seen to be altered. There are nodes to validate that change. Only after most nodes’ verification, the data is in the blockchain. It makes it transparent and very strong in privacy.
In Web 3.0, not only blockchain technology but also technologies such as AI and IoT are connected together. IBM, Amazon etc. are working on Web 3.0.
Just like when Web 2.0 came, millions of jobs like graphic designers, content managers, social media handlers etc. were created. Similarly, Web 3.0 is likely to create more jobs.
In Web 3.0, new jobs like blockchain developer, solidity developer, smart contract developer, and smart contract auditor will be created.
With the development of Web 2.0, the world’s largest companies such as Facebook, Amazon and Google emerged. New companies are also likely to emerge in Web 3.0.
How to prepare for Web 3.0 and Blockchain technology?
The main technology behind Web 3.0 is blockchain. It can be used not only in Web 3.0 but in many places from business to digital ownership. Blockchain technology is also ‘evolving’.
But if we start learning this technology now, it can give a new shape to Nepal. Nepal can also be in the leading position in Web 3.0 and blockchain technology.
Since blockchain technology is evolving, there is not much difference between other countries and Nepal. There are also books, and online courses related to blockchain technology. Solidity, Rust, and R programming language are required to become a blockchain developer. People who come to programming language can also shift here.
Blockchain technology useful to the government
Blockchain technology is beneficial for the government. The government is also the largest producer of data. The government has many types of data. Blockchain technology can be used for the privacy of such data.
In this technology, all this is known when the data is changed. There is no third-party involvement in the transaction. Business is easy. Blockchain technology can be used in voting, real estate registration, licenses etc.
Then the customer can be given a ‘unique token’. All customer details are kept in that token. No one can access the customer’s data without their consent.
