Enter “Web3” and “Dachang” in the Baidu search engine. Jumping out is basically such a title?
And today’s Internet industry “sorrows everywhere”, not only involution, but also layoffs. Then a gust of wind blew up and slammed Web3, and the data returned to users… Finally, “coerce and induce”, Web3 is the Internet 20 years ago, hurry up and get on the bus, and it will be too late.
So what exactly is Web3? This vernacular blockchain brings you a secret to easily grasp the key points of Web3 in 15 days. Let’s read it together!
01
Day 1: What is web3
Web1 can only read – web2 can both read and create – web3 is about reading and creating ownership. When we use social media applications in web2, all data is stored on company’s servers, and most large platforms are processed by only a few companies.
We contribute our data to these companies and rely on them. But do we really want to do this? Just because we have no other choice.
Just as artists never really own what they make, we don’t “really” control our money. But banks can, banks have the right to freeze someone’s account, and there have been many times in history where withdrawals have been stopped.
This shows how centralized the world we live in is!
There are many other examples of why we need a decentralized and web3 world and why this is important.
It’s easy to understand if you know about sound.xyz (a music site) and how it helps artists create independently and make more money through ownership.
Centralized platforms have dominated for so long that many people forget that there are better ways to build internet services.
And Web3 based on encrypted network is such an existence, which provides a level playing field for third-party developers, creators and enterprises, and is a network shared by the development community.

Day 2: Blockchain Basics
A blockchain is a shared ledger of “blocks” or data – everyone can see what is happening and all transactions in real time.
If trust can be set through code, then creators don’t have to rely on middlemen.
They: don’t have to go through a bank to get money; don’t have to trust a lawyer to draft a contract; don’t have to rely on the internet to make a living.
The three characteristics of blockchain are:
Decentralization: Transactions are stored on a network of computers (nodes).
Immutable: Once a transaction is committed to a block, it cannot be changed.
Open and transparent: anyone can view transactions.
Bitcoin uses the blockchain and is therefore decentralized, immutable and transparent. This is also due to:
Hard cap: 21 million bitcoins forever.
Single-purpose: Many holders just want it to be a digital token that stores value.
From a developer’s point of view, it’s a backend that never goes down, and people can anonymously see what everyone is doing by their address. A product can be deployed and used to create a decentralized application, and everyone owns what they produce.

Day3: Wallet, Consensus Algorithm
On the blockchain, your wallet is your identity, yes, there is no name, only the wallet address. An online wallet is like that wallet in your pocket – we need it to store money.
These wallets are either software (eg, Coinbase, Metamask) or hardware (eg, Ledger).
The easiest way to learn is to try something. Find a platform where you can buy some crypto assets. Set up a wallet like metamask, transfer money to that wallet, and see if you can exchange some tokens.
Every wallet has a security key that needs to be kept safe to make sure you don’t lose it. In most cases, most people will use CEX to manage their funds, such as binance and coinbase.
A consensus algorithm is a process used in computer science to agree on a single data value among distributed processes or systems.
Proof of Work (POW) and Proof of Stake (POS) are the two main consensus algorithms.
POW: Nodes (miners) try to solve the problem – the first person to solve the problem gets rewarded – other nodes check if it is correct.
POS: Miners use their shares to solve the problem – other validators check it and get their shares in the right case – eventually adding the block to the chain.

Day 4: Ethereum and other coins
Unlike Bitcoin, Ethereum has a complete programming language inside, so programmers can write code and make applications on Ethereum.
Bitcoin is a digital gold that acts as a store of value and medium of exchange. Ethereum is the infrastructure of digital cities, and it is considered the foundation upon which businesses and applications are built.
You can use the Solidity language to write smart contracts and then build decentralized applications (dapps) on top of the Ethereum blockchain. You can develop other chains – eg polygon, solana. Think of the blockchain as a powerful backend database that stores things for you and keeps running!
For coins, we see coins everywhere – according to some, Shiba Inu and Dogecoin are going to the moon. Unfortunately, they don’t have any logic behind these products! They are just meme coins.
There are a lot of great ideas behind a project like Ethereum, and a complete “token economics” structure is established before launching a product.
There are other stable Bs that earn passive income through pledges, income farming, and borrowing. For example DAI, USDT, etc.

Day 5: Defi
DeFi (Decentralized Finance) is a movement aimed at building a new financial system that is open to everyone and does not require trusted intermediaries like banks. To make it happen, DeFi relies heavily on cryptography, blockchain and smart contracts.
That is, DeFi refers to “a financial application ecosystem built using blockchain technology without the need for banks to intervene”.
A great reason to learn Defi is that some apps have an APY (annual rate of return) of 10%-20%, compared to banks’ traditional rate of return of 0.01%. Think about it – the rate of return on your money could one day scale up to 2000 times!
There are also some very important concepts, such as pledge, borrowing, income agriculture, etc., which can be understood by yourself!

Day 6: NFTs
Alternative tokens are homogenized (eg, usdt, bitcoin). Non-Fungible Tokens (NFTs) are unique (eg, art, music, domain names).
NFTs are not just images, take ownership as an example, you own your house -> you want to sell it -> every time you sell it -> you get some ownership royalties. The same goes for artwork or anything else, and you get royalties from buying and selling.
Artists have been selling what they make for years without earning an ownership gain. Now they can turn to their true fans with the help of encryption and Web3 and make more money from the work they do.
NFTs are also widely used in games.
How to buy, mint, sell? Go to opensea, connect your metamask wallet, and buy your first NFT. Want to upload artwork you own? Go to the profile section and upload your image to the blockchain via their dashboard to get your exclusive personal creation.
There are many other use cases for NFT, which are not listed here due to space constraints.

Day 7: The Metaverse
Today’s generation is playing with their mobile phones every day and spends most of their time online. According to this trend, the next generation will spend more time on the Internet. The Metaverse gives the Internet a new level of interactivity. It can be said that it has opened up a new innovative industries.
The Metaverse is more about time, place or virtual reality. Like Sandbox, it is a marketplace in the metaverse where people can buy and sell NFTs.
Decentraland – an online virtual world with an expansive map of 100,000 lands, originally sold in 2017 and now has a floor price of 1.8 ETH. People can own land in it, build on that land, and customize avatars.
People are buying millions of virtual lands and creating online identities in virtual worlds. Soon, people may be wearing VR headsets, having meetings at home, buying more virtual lands, playing more games, and more.
A large portion of NFT projects in 2021 are committed to being compatible in the metaverse, or creating their own metaverse!
Today’s learning tasks:
1. Popular games

Day 8: The DAO
DAOs are decentralized autonomous organizations – they run spontaneously without leadership. This radically reduces the risk of corruption and other misconduct.
For example, MakerDAO Token holders who build a decentralized stable B can manage the system and vote on parameters such as fees.
We’ve also seen DAOs emerge that cater to more specific investment opportunities, such as owning NFT artwork and virtual gaming projects .
There are many tools for creating and coordinating DAOs, such as Aragon, DAOStack, so people don’t have to build everything from scratch.
DAOs play a big role in group relations, regularly iterating on ideas to keep them intact.

Day 9: Play games and earn money
Play 2 Earn and the rise of metaverse games are among the biggest innovations of 2022. Gaming is often described as a potential breakthrough case for bringing more “norms” into Web3.
Axie Infinity is a Pokémon-like game built on the Ethereum blockchain, where people buy digital pets called Axies as NFTs and breed, fight, and exchange them.
In April 2021, Axie’s revenue was about $670,000. In May, it made $3 million. In June, $12.2 million.
In Fortnite, everything a user buys is cosmetic. While buying a certain skin won’t give you a better chance of winning battles, just like buying a new shirt won’t make you stronger. People do it just to show off, or for a personal touch, or out of a desire to spend on fancy stuff.
There are many learning-based games, such as Crypto Zombies, through which you can learn relevant technical idiosyncrasies and the basics of Ethereum development.
Japanese mobile game Ni no Kuni: Crossover set a speed record in June, reaching $100 million in revenue in just 11 days despite launching in only five markets so far.
The metaverse is a virtual environment that emerges from an augmented or virtual reality space. Splinterlands (built on the Hive blockchain) is a dynamic example that has shown explosive growth similar to Axie by offering digital land titles.
Today’s learning tasks:

Day 10: Smart Contracts
Smart contracts are the foundation of all decentralized applications. Just like you see in a web2 application for user authentication, servers, backends – smart contracts are the basic stuff that needs to be added.
Learning smart contract development means learning Solidity, the programming language behind it.
But the difference is the deployment function, the payment write function, the use of the testnet for different tests, the write needs to be accepted by the network, everything is public, it is difficult to put on the chain, and so on!
There are plenty of interactive games like Crypto Zombies that can be played to learn.

Day 11: Asset Allocation Fundamentals
The crypto market is the most volatile we’ve ever seen, and people’s FOMO (short for fear of missing out) occurs the most here.
There are no surefire stocks or crypto assets to buy in this world. It is good to do your own research and hold for the long term by holding in the most popular projects like Bitcoin and Ethereum.
A lot of KOLs have different opinions on stable B and newer projects, and most of them get paid for what they say, so make sure to do your in-depth research before jumping in.
At Coinbase, Binance and other CEXs, you can buy crypto assets through your bank account. You can then transfer the money to a wallet or hardware storage device.
Defi offers a variety of options for passive income through borrowing, staking, and yield farming. Please read the conditions of each platform – usually DEXs have a stated date, which means that the DEX will hold the amount for a certain period of time.

Day 12: Oracles, Chainlink
Smart contracts need something to interact with real-world data. And we can’t rely on a single point of interaction to get this data. The data we get is still centralized. If the company that provides the API (application programming interface) fails, the API we use in a simple application could bring the application down. We solve these problems using a solution of oracles, which act as a decentralized way to enter real-world data into smart contracts.
One of the more leading oracles is Chainlink. Chainlink is a decentralized blockchain oracle network built on Ethereum. The network is designed to facilitate the transfer of tamper-proof data from off-chain sources to on-chain smart contracts.
If you use an external API, you’re actually putting decentralization at risk, because the API is centralized and owned by one entity, so if the API fails for some reason in the future, everything is scrapped.

Day 13: Altcoins – Eth, Sol
Any coin or project other than bitcoin is called an altcoin, but the huge success of ethereum, solana, and other projects doesn’t really justify the name.
Many altcoins are built using Bitcoin’s basic framework, providing the ideal “peer-to-peer” connection for most of them. Also, in imitation of Bitcoin, they are designed to provide a cheap and efficient way of transacting.
Ethereum is the largest altcoin and we have seen its potential.
Another well-known altcoin and project is Solana. It is faster and cheaper to build related projects using Rust as the underlying language. If you are interested, you can check the relevant resources yourself.
Another reason why altcoins are important is that they are excellent profit-makers. With Bitcoin’s success, people wanted to get to the bottom by creating and exchanging new utility cryptoassets – and then selling it when its value rose.
For finding stablecoin value and market cap, go to the coinmarketcap website.

summary
In general, Web3 is an ideal network architecture that is ultimate, open, trustless, and permissionless. It integrates all cutting-edge information and eliminates the monopoly of giants. Everything is user-centric and controls data independently.
If we delve into the principle, we will find that Web3 is not the opposite of the Internet. On the contrary, it is born out of the Internet and is an “open Internet” that the Internet hopes to build at the beginning of its birth. Only after more than 20 years of development, Internet practitioners have not achieved their original ideals very well. On the contrary, in the form of existence and technical structure, it seems that the Internet is becoming more and more besieged cities with high walls of monopoly. However, the future is bright, but it is still a tortuous road!
What difficulties have you encountered when entering the Web3 and encryption industry?
