1.2 The Era of the Blockchain (The Era of Web 3.0)

Over the past 30 years, IT technology has developed remarkably, and a number of services that utilize it have appeared. In the early 2000s, messages were exchanged with friends through messaging services, and each time a message was sent, it cost $0.01 and $0.03. However, in the 2010s, smartphones became popular, and messenger apps such as WhatsApp, Telegram, and Line were created, which allowed us to send and receive messages without paying any money.

Not long ago, we had to pay to send a message, but with the advent of smartphones and messenger apps, we can now send not only messages but also photo files and video files for free. How will the message exchange method have evolved in another 10 years?

Maybe the time will come when you will receive money (SendToEarn) every time you send a message using a messenger app service?

Over the past decade, we have seen companies that provide free messaging services such as WhatsApp, WeChat, and Line growing into giant companies that generate huge profits. I think anyone can think of a scenario where, in the next 10 years, a company that pays you every time you send a message using their service might appear and grow into a company as big as WhatsApp or WeChat even if they don't have a rich imagination. Imagine that! This dream may soon become a reality!

Now, we can issue and distribute tokens and NFTs through blockchain technology. Tokens and NFTs, which exist on blockchains, cannot be hacked. And since they are stored in a distributed database, anyone can access the data, which means transparency is guaranteed, and they can be used as a safe currency or a means of storing value. Depending on the usage, tokens are sometimes used like money, sometimes like gold, or even like stocks. Thanks to these tokens and NFT technology, we can give independent value to all the products and actions that humans create in the digital world by paying tokens. The entire technology and system encompassing the blockchain that gives value to all digital products created by humans, as well as stores and distributes them is called Web3.0.

Through Web3.0 technology, it has become possible to add value to every human activity that uses time—such as playing games, watching news, walking, or writing—by paying tokens. In other words, now we can create a variety of services that we couldn't do before, such as Play2Earn that pays you for playing games, Read2Earn that pays you for reading news articles, Walk2Earn that pays you for walking, and WriteToEarn that pays you for writing. It is expected that numerous ServiceToEarn (S2E) services will appear in the future due to the acceleration of the digital society and the addition of human imagination.
