What is Web3? Why should I care?

“Web2.0” was still a new concept when I started my career.

The word "2.0" in Web2.0 captures several things: blogging, rounded corners of buttons and input fields, and online media sharing. But in fact the difference between Web2.0 and "Web1.0" isUser creates content. In the "1.0" era, to publish content to web pages you really have to send the HTML file to a server connected to the internet, and if you are a webmaster you also have to be a little bit CSS or JS. It is not a friendly process and is certainly not accessible to ordinary people.

The idea of ​​users creating content is that the website allows users to access the content and then save it for everyone to see. It was originally used to help blogs like LiveJournal and Moveable Type, and later to create social networks like MySpace, Facebook, Twitter, and wordpress.com where people still matter equally. Users do not need to manually edit files and upload them to the server. You can even leave a comment under this article! Although this concept may seem trivial today, the Internet has become an interactive medium, where anyone with an Internet connection and constantly cheap computer can spread to other worlds, anyone can print content. This is a major change in the rules of the game, for better or for worse.

If you asked someone who had an idea of ​​what Web2.0 would do, most people would say, "Is this a blog?" Someone who shared a murder meme on Facebook or a dance video on TikTok. At one time, the idea of ​​getting ordinary people to post something on the Internet was so new that it was impossible to predict what format was going to be created and what the terrible danger was that would open the door to hell.

Web 3

The term "Web3" is used to describe similar changes in education.

Before I jump into Web3, I want to talk about the cryptocurrency hype. Cryptocurrencies attract a lot of people, and many of them are drawn to the stories of getting rich without working. That's the whole cryptocurrency ecosystemimpact, even if some needs are based on an organization or a specialized product that will (or not) be genuinely useful and beneficial at one time or another. This sentence is not about cryptocurrencyA technology platform that can support many new technologies and services that were previously impossible.

What drives the world of Web3? What is the bottom layer? With the help of blockchain technology, a new set of key concepts for application development is available. The main factors affected are:Log in,lying is not enoughyetGlobal employment and the state. It is not easy to explain the details in layman's terms, but I will go into the details about them. So, I'm going to delete a lot of them.

1.Log in(Cryptographic Identity): In the world of Web3, you are often referred to as “Cryptographic Identity”.wallet(wallet). The only thing you can control yourself (and your wallet) is physical or good. "Private key"(Private key). If you have a private key, you can prove who you have."Public key"(Public key) is yourswallet. What does it mean?

In the Web3 world, you are your number one asset, this is where your wallet is.. This creates a lot of possibilities because only you (the owner of the private key) can prove yourself. Here are some examples.

You don't need to create a new account for every website or app you use.

You don't need to trust Facebook, Google, Apple, etc. to prove yourself (unless you want to).

People can only encrypt data if you can decrypt it and read it without any communication with you, and you can make the encrypted data public. Only the owner of a special private key can decide on this declaration. As shown below.

Sign in any language, like online voting or sign a contract.

A powerful electronic identification system such as the e-ID provided by the Estonian government.

Anonymous ID once. If you want, you can create a new ID (public key / address in wallet) for each website or interaction.

Ownership or maintenance of money or assets. You can activate via multiple signatures.

Join all types of files with encrypted numbers, such as driver's license, video game loot, etc. It can be used in any application. Do not store on the company's dedicated servers, you have all this information.

Make sure you communicate with people because there is nothing else you can do without stealing their private keys.

Above: Bob uses Alice's public key to encrypt the "Hello Alice" message, and Alice can use her private key to determine and read the message.

Confidential information has endless other possibilities and of course there are new issues that can cause a lot of damage. The most obvious is that people can easily lose their private keys. Therefore, it is important to safeguard your personal keys, for example by writing a mnemonic note on a piece of paper and putting it in a safe place. You might think that there would be a lot of horrible reports explaining that some people have lost their lives in a computer crash. Of course, just as you can get a bank account so you don't have to hide your money in bed, some trustworthy (or scam) organizations that provide support to people using data and data backups can also happen to work with people and keep their keys private. not found. .

2.lying is not enough(Artificial shortage): It is the best known at present. Blockchain technology has used many ways to limit the amount and quantity of digital assets. For example, there are only 21 million bitcoins, and if your large number proves that you have a wallet with bitcoins in it, you can turn them into a nice house or into a Lamborghini.THE T.V(Heterogeneous Tokens) allows you to create your own assets. We are just starting to use this tool and the prospects it will bring are unprecedented. For example, if you want to send tickets to an event, but only have 100 people, now you can use digital NFTs to do so and resell digital videos, video games, or names that people change or buy. Works.

Community members are required to hold certain tokens to become members of the DAO team, the DAO Friends with Funds organization is a prime example. If there is only a small number of FWB tokens, it means that the tokens have value. Those who already hold tokens but are not happy with their membership can sell their tokens to people who wish to become members. The higher the reputation of the organization and the better the participants, the higher the value of the token. Since the members of this DAO are insurers, it is interesting to increase the value that the organization offers to its members. In this way, a virtuous circle can be created. Management issues can depend on the number of tokens a person owns, as people with multiple tokens are involved in the project. Or you want to be honest, you can't judge by the coins you have. Competition from different organizations is good.

Understanding this concept is very important and powerful. This technology leads to new forms of organization and management.

Artificial scarcity, intelligent link and self-identificationThe union of is a great formula for a new way of planning and collaborating with people all over the world.. Now, no one knows what works best for each organization, but there will be many trials over the next year or so. No technology can be more than a combination of human behavior for a purpose. Let's look at how nation states or organizations are changing the world for better or for worse.

Currently, these tools and procedures are still in their infancy. Of course, technology cannot solve all organizational governance issues while having the level and interaction of people needed. However, some of the processes that now rely on credible and fair legal procedures to ensure current corporate governance and membership may refer in part to smart contracts (such as voting, approvals, governance, etc.) . In theory, however, the investments, memberships and partnerships could extend to anyone in the world who owns a smartphone, not just a few important people who may own a smartphone and use the law or the border country. .

Seeker groups around the world can participate in fundraising activities like ConstitutionDAO, running and releasing as they see fit. It could be for a business, partnership, nonprofit, small country, theater, or a large part of a new organization that we've never seen before. It's impossible to predict how all of this will turn out, but we've seen the outcome of many DAOs managing billions of assets (see DAO dashboard below) and we're still ahead too. This is my favorite part.

To give another good example: Gitcoin is a nonprofit DAO organization that receives open funding for development. Recently, you can help get started by investing some of your GTC tokens in the new DAO. , this is the DAO developer. . The investment deal is open to the public, and Gitcoin DAO members can vote, and the deal will exchange the newly created DAO tokens for 50,000 GTCs worth US $ 680,000 at the time of writing.

The DAO developer plans to use the GTC and other funding to fund the development of the new Web3 and help engineers develop free Web3 technologies. DAO developers can invest in these new tokens with their own tokens and trade tokens to earn a percentage of the token members in the new tokens. In this way, each organization can invest a part of itself in new companies, and these investments are represented by their own tokens and can be part of their members. It appears that the company is investing its capital in a new company without a business deal (estimates can be provided by Uniswap's cash pool). In this context, we are talking about the organic combination of nonprofit businesses and the benefits that share the risk, investment and management of each other, and everyone, optional and with little friction.

Three.Global employment and the state(Global and State Operations): We now have virtual machines all over the world.Machine virtual Ethereum (EVM),Full history, function and usage history are shown. These virtual machines can be used for any reason to write programs that anyone (for a fee) can download and run, like many financial applications (DeFi) that exist today. . Today, these services are mostlysmart contract, this is only a usable tool. What can people do with this technology? Just as it's hard to imagine what a smartphone would look like when the personal computer (PC) revolution began, it's impossible to imagine when it was young.

Above: Blockchain is the global sharing and distribution of business information.

These virtual machines are distributed all over the world and can be easily exchanged and distributed. Although DAO administers standards for virtual machines and process interference, no one "owns" Ethereum. As the DAO received new recommendations, many software developers have shifted their use of the Ethereum network for changes and upgrades. Although this is a voluntary process, it works very well and is no different from the application process and standards that the International Internet Engineering Task Force (IETF) has managed on the Internet for many years.

Machine virtual Ethereum

Also to be noted.Zero proof(Proof ZK) You may receive personal information such as anonymous business and SMS. Of course, this could be used for malicious purposes, but it also opens up the possibility of a free exchange of information and attacks against tyranny. However, it will be a skill that people have to do.

web history

Why should you pay attention to Web3?

I started liking Web3 about a month ago. When I go out to see what's going on on website3, I see a whole new world. Many engineers are aware of the potential of this field, let alone the smartest entrepreneurs and technologists. The excitement is real and the energy of the community is uplifting. I work with a DAO developer. This is a new community where people come together to create coolers and help others learn how to use these new gadgets.

As with any change, some experts consistently criticize and disrespect this newfound anger, seeing it as temporary fake anger. Cloud computing has been criticized by Oracle CEO Larry Ellison and others, as well as some have criticized the performance and dedication of the PC that it cannot match the mainframe, and some have criticized the weakness of the graphical interface. One thing for me is that the iPhone looks dumb.

The basics of Web3 are cryptocurrencies and blockchain (L1) solutions. It's not something that anyone or anyone other than technology can use. Because there are multiple interfaces to interfere with. However, at this point the development of additional abstraction (L2) tools and procedures has started to be modeled and implemented, and it is now possible to build Web3 applications with user interfaces. Sooner or later we will see the emergence of new types of communities, organizations, symbols and new applications to achieve more than anyone could have imagined. Of course, there will be tons of deception, just like the collapse after the first dot-com bubble. My idea is to ignore trivial situations and distractions, focus on technology, tools and communities and see what people are creating using Web3 and changing the world.
