This year, all the focus is on the metaverse, but few people understand what exactly is Web 3.0, the vital infrastructure of the metaverse?
Every major development of mankind is produced on the basis of scientific and technological progress.
Back in time 20,000 years ago, the progress of primitive people benefited from a forest fire caused by lightning. The fire raged for three days and three nights without being extinguished, and the ground was covered with the remains of animals and plants.
Perhaps hunger is more devastating than the fear of a raging fire. At this time, a primitive man who was hungry for food walked towards the pile of roasted black venison. There was no trace of blood in the smell, which made him feel uncomfortable, but slowly a burnt aroma spread to him along with the chewing action. of the internal organs.
At that moment, he realized that he was no longer even afraid of the jumping flames, and he would take the initiative to put the limbs of animals on the flames to bake, and then he also learned to save the fire and use tools to make the fire.
From fearing fire to using fire, this is the first technological revolution in human history.
Minor gaps can make a big step forward in the times.
Now when we see a stone, you may not have any feeling in your heart, but for primitive people, the stone is the key tool for them to evolve into the master of the earth. The second technological revolution.
Humans with tools are even more powerful, and in the process of continuous evolution, the third technological revolution of human beings has also begun to flourish.
When the alchemist obsessed with alchemy came up with the formula to replace the copper by putting iron into the copper sulfate solution, human beings won a decisive victory in the war with other races, and at the same time the development of tools also reached a higher stage , far surpassing the power of earth, stone and wooden sticks.
Let's go back in time to the 18th century. In 1769, Watt improved the efficiency of the steam engine on the basis of promoting the process of the Industrial Revolution and also brought about a change in energy.
After that, the productivity of human beings has undergone earth-shaking changes, and with it comes the rise of the whole of Europe, and the United Kingdom, which took the lead in completing the industrial revolution, also wears the name of world hegemony.
Back in the 1990s, the emergence of the Internet has greatly strengthened the connection between all parts of the world, and we have begun to enter the so-called information age.
It seems that as long as the network can reach the place, even if it is far away, it can be connected in real time. And all the giant companies we are familiar with today were all born on the basis of the Internet technology revolution.
Three stages of web development
The network has three layered periods.
Summarizing these three periods in a super simple concept are:
Web 1.0: Portals are mostly content with little interaction;
Web 2.0: Facebook, blogs, Weibo, etc., users are deeply involved in the information, and the interaction increases;
Web 3.0: Blockchain data is the mainstay, and creators will own the network (the underlying assets).
Web 1.0, the portal website, once stood at the center of the Internet stage. When countless streams of information flew past our eyes, the era of information explosion was born. But the only fly in the ointment is that the information we can receive is edited and released by the website operator, in a state of passively receiving information.
With the birth of the mobile network on the mobile phone, the era of Web 2.0 has arrived. During this period, users interacted with the platform a lot, which in turn changed the way information is produced and obtained.
Everyone is deeply involved in the message. This is the biggest feature of the Web 2.0 era. At the same time, products such as blogs and microblogs were born, allowing users to upload and publish content by themselves. Since that moment, the amount of information on the Internet has grown at an unprecedented rate. Just one day's flow of information is equivalent to 10,000 times the sum of the previous 5,000 years of information.
The essence of human beings is to like the new and dislike the old. As human beings develop the Internet more and more deeply, the freshness that Web 2.0 can bring to users will become less and less.
No matter how the mobile device is updated, you will not be deeply affected by it. No matter how many apps are used, you will at most feel useless.
The reason why innovation is tied up in the Web 2.0 era is that the current underlying technology urgently needs to be innovated.
Thus, Web 3.0 appeared. The biggest difference between Web 3.0 and Web 2.0 is the change in production relations.
The return of decentralization
Although the network in Web 2.0 links everyone together, the speed and volume of information increase exponentially, and everyone can get information and enjoy various services brought by the network, which seems fair. Yes, but network management is more complicated than you might think.
For example, in the past we were at most message publishers and participants on the web, but the feedback we could get was very limited, and we could neither decide nor change anything.
Because platforms and telecom operators have the right to manage and monitor what happens on their respective sites. This is why Trump's account can be blocked so easily by Twitter, and this is also why various platforms can collect users' consumption habits, and then another wave of big data to kill them.
But this situation is completely different in Web 3.0, which returns data ownership to everyone in a "decentralized" way.
In 2008, a self-proclaimed Japanese-American named Satoshi Nakamoto published a paper on the cryptography mailing list of the website "metzdowd.com" titled "Bitcoin: A Peer-to-Peer Electronic Cash System".
The paper describes in detail how to create a decentralized electronic transaction system, and this system does not need to be created on the basis of mutual trust between the transaction parties.
This new data model library proposed by Satoshi Nakamoto is today's blockchain technology.
Later, in order to encourage more people to participate in the blockchain, the blockchain issued a currency-Bitcoin to all supporters. As long as the participants are willing to contribute to the development of the blockchain (provide computing power), they will definitely receive Bitcoin as a reward, which is the so-called change in the production relationship.
In addition, participants can also influence the development of the blockchain by voting, so countless people joined the mining army, and the profession of "miner" was born.
However, Bitcoin is only the most basic model for building a blockchain, and it has no practical use. In the Bitcoin chain, apart from mining, nothing else is done.
In order to have a higher degree of freedom, miners invented the new chain Ethereum.
On the Ethereum chain, in addition to mining, you can also develop various applications yourself, making Ethereum a programmable platform. At the same time, at the lower end of the total chain of Ethereum, many sub-chains have grown, and those who provide these sub-chains can get a certain reward.
Ethereum feels a bit similar to Apple's iOS system, and every year Apple absorbs more meaningful technologies into Apple's developer conference. But the only difference is that the iOS system will always belong to Apple, and any external technology developers have no right to speak.
Ethereum, which grew up in the Web 3.0 era, is different. As long as you increase the value of Ethereum, you can get economic benefits from it. In theory, even individuals could become ethereum masters if the value provided is large enough.
This form is a bit like in ancient Roman times, citizens could cast their votes on major issues to influence the development of major decisions. This is because the changes brought about by Web 3.0 are technological reforms, which can allow data and the benefits brought by data to return to individuals, and let the private key be in the hands of the user, with a high degree of freedom.
Be the master of technological data
The change in the underlying technology of blockchain has brought about changes in human thinking and production relations, and more importantly, it has reshaped the focus of world science and technology.
In terms of production relations, we have completely become the masters of data to a certain extent, and are no longer subject to the constraints of any platform or telecommunications provider.
In terms of way of thinking, we originally thought that offline life was essential, but after the epidemic, we need a virtual world to complete a series of activities in life, so the concept of the metaverse will become unstoppable after the epidemic.
Instead of being beaten madly in the real world, it's better to go to the virtual world and get drunk. Before the epidemic, it was essential to check in at work. After the epidemic, telecommuting has become a general trend. In recent years, "decentralization" has been mentioned more and more times.
The reason why human beings can become the species that can rule the earth among all animals is simply because human beings have higher creativity and adaptability to change.
The epidemic is changing all the time. In order to make life return to normal, we must think about better ways of social organization. All these changes stem from both environmental changes and technological progress.
In the era of Web 3.0, if you still regard the blockchain as a leek-cutting activity, or you will only chase up and down, then you are really too naïve.
Blockchain is the most significant technological innovation of mankind in the era of Web 3.0.
Based on the blockchain, the metaverse will be realized, new ways of decentralization will emerge, and individuals will truly own the assets you participate in.
Now, with Bitcoin and Ethereum as the two core main chains, the asset value has exceeded 1 trillion US dollars. Moreover, this figure was achieved in the case of a serious shortage of computing power. Who can resist this charm.
The current computing power can be increased by at least 10,000 times. Under the circumstance of breaking through the technical bottleneck of computing power and ideal calculation, assuming that we can increase the computing power by 10 times every 3 years, after 12 years, we can achieve the goal of increasing the computing power by 10,000 times.
At that time, the real new era will come, and the trend of the times cannot be changed. All we can do is embrace it tightly.
