Hello everyone, today we will talk about Babylon.
The name 'Babylon' is quite interesting; in English, it translates to 'Babylon', the lost ancient civilization. However, as a Chinese person, the first time I see this name, I interpret it as: baby | lon, baby dragon. The official image indeed resembles a little dragon.

But after reading the white paper and papers, I feel that Babylon, although currently just a little dragon, has the potential to grow into the 'Longmen Escort Bureau'.
What does Babylon do?
The official Chinese slogan is: Unlock 21 million Bitcoins, protect the decentralized economy.

Hello friends, today we are discussing SolvProtocol.
This is a relatively new project and has not yet issued a native token.
What problem does Solv protocol solve?
The official documentation defines itself as: On-chain Bitcoin Reserve
A blunt understanding is to create DeFi for BTC.
I have previously written about DeFi-related projects; DeFi stands for Decentralized Finance, taking the first letters of both words. The projects we've shared in the past have been concentrated in the Ethereum network, but BTC, which occupies half of the cryptocurrency assets, has rarely been mentioned. Why is that?

Hello friends, today we are going to talk about the recent skyrocketing XRP.
From around $0.5 in early November, it has risen all the way to nearly $3, and the project's market value has also jumped to third place, following closely behind Bitcoin and Ethereum.
Before we talk about why XRP is rising and whether it can continue to rise, let’s first talk about what XRP does.
What is XRP
In a nutshell, XRP is the native token issued by the public chain XRP Ledger protocol.
In the previous introduction of Sol, we roughly compared the public chain to an operating system, which is the cornerstone of the blockchain ecosystem. The XRP token is the native token of the Ripple public chain. This analogy is like Bitcoin is the native token of the BTC network.

Hello everyone, today we’re discussing Solana.
Solana is a high-performance public chain known for its fast transaction speed and low transaction fees.
The first question is: What is a public chain?
What is a public chain?
ChatGPT's answer is: A public blockchain is a distributed ledger technology network that anyone can freely participate in and access. It is the most typical form of blockchain technology, aiming for complete decentralization and openness.
Let me translate this into simple terms: public chains are infrastructure, the foundation of a decentralized world.
A simple analogy: public chains are like operating systems. For example, iOS, Android, Windows, Linux; they are all infrastructures, with software, applications, and apps built on top of them, involving developers, users, and service providers who create services and ecosystems, making money off each other. At first glance, these operating systems seem quite similar; they can all send WeChat messages, make phone calls, play games, etc. Users know that the systems of iOS and Android are different, but can't specify how.

Hello friends, today we are going to talk about Lido.
Lido defines itself as a liquid staking solution.
In simple terms, you can stake ETH through Lido to obtain staking income from the Ethereum network, while not affecting the liquidity of the token and continuing to receive additional rewards from other Defi protocols.
Let’s start chatting.
What opportunities lie ahead for Lido?
This starts with Ethereum's transformation from PoW (Proof of Work) to PoS (Proof of Stake).
In the past, the Ethereum network, like the Bitcoin network, used proof of work to maintain network security.

Hello everyone, today we will discuss from a data perspective: Is Bitcoin really a Ponzi scheme?
Recently, the price of Bitcoin has been rising all the way, reaching a peak of $99,000 per coin.
In the comments under the news, there are probably two factions: one advises everyone to be cautious, questioning why there are still fools believing in such an obvious scam, which is clearly a Ponzi scheme designed to lure you in and then harvest your profits;
Another perspective is that you don't understand, so don't speak thoughtlessly. Those who hold it are already financially free, so quickly buy some while you can still afford it.
I can easily be persuaded by others; both sides seem to have a point.

Hello everyone, today we will talk about Synthetix.
"The mystery of 'synthesis'"
Synthetix positions itself as a decentralized liquidity supply protocol, with two key terms: decentralized and liquidity supply. Decentralization is easy to understand; we will elaborate on liquidity supply.
In the DeFi world, mainstream liquidity provision comes from exchanges, which can be centralized exchanges, such as the leading centralized exchange Binance, using an order book to match user trades; or decentralized exchanges like Uniswap, using AMM (Automated Market Maker) to provide liquidity for traders.

Hello everyone! Today we are going to talk about Curve.
Curve defines itself as a decentralized exchange (DEX) and automated market maker (AMM) on Ethereum and EVM-compatible sidechains/L2, aiming to facilitate effective trading between stablecoins and volatile assets.
Let me translate it. Curve mainly provides trading services for stablecoins.
With Curve's official mainnet launch, Uniswap has already set a precedent as a decentralized exchange. Where does Curve's differentiated competitive advantage lie? To answer this initial curiosity, let's have a discussion.

Hello everyone, today we are discussing RGB++.
The impossible triangle can only ever choose two out of three.
In the world of cryptocurrency, there is an impossible triangle: decentralization, security, and scalability, of which at most two can be satisfied.
For BTC, the choice is decentralization and security, which is why we see that Bitcoin's network can only complete 7 transactions per second. This speed is not even comparable to peak settlement efficiency in e-commerce, and it completely fails to keep up with the pace of everyday economic activities.
Are there any solutions that have both good performance and high security?
Of course, there are options, but it requires sacrificing the degree of decentralization. For example, the credit cards we currently use, Visa and MasterCard, have been securely operating for many years. They are indeed fast and secure, but the downside is that they are centralized organizations.

Hello friends, today we are talking about Aave.
Aave's predecessor was ETHlend, founded by Stani Kulechov in 2017 through an ICO. The name 'lend' reflects that this is a lending protocol, and the prefix ETH indicates that it is primarily based on Ethereum assets, allowing users to borrow assets through collateral. There was a simple introduction to the decentralized lending business model in previous posts; you can check out the question 'Can you still get loans without banks? What is decentralized lending?'
In 2019, ETHlend officially changed its name to Aave. Aave means 'ghost' in Dutch. It implies that although the medium is transparent, it is powerful, corresponding to a lending protocol that can provide transparent, safe, and efficient services.

Hello everyone, today we will talk about the economic model of tokens.
Projects introduce the economic model of tokens in their ICO fundraising or project white papers. When we talk about the token economic model or token economics, what exactly are we referring to?
What is token economics?
The most fundamental theory in economics is supply and demand theory. When we talk about token economics, we are generally referring to the design of token supply and demand.
The theory of supply and demand simply means that supply and demand jointly influence prices. For example, if meat prices rise in the market, farmers will see a profit and will raise more pigs; this is price increase and supply increase, with a positive relationship between supply and price. Conversely, if egg prices are particularly high while vegetable prices are decreasing, more people will buy vegetables; this is price decrease and demand increase, with a negative relationship between demand and price.

I recently watched the MIT course on Blockchain & Money; it's really great, highly recommended. It's available on Bilibili, and although the Chinese subtitles have some odd translations, it doesn't hinder the understanding of the essence.
The teacher is Gary Gensler, standing in formal attire at the podium, trying hard to remember the names of students in the class and patiently answering every question. Most importantly, he speaks at a pace that allows me to understand him; he is truly charismatic.
I know he is a big shot, but it wasn't until just now when I opened a search engine to supplement more information that I learned he is now the chairman of the SEC in the United States. It reminds me that in January this year, the SEC approved the first batch of Bitcoin ETFs. Behind this decision is this balding old man in his sixties, looking at you with bright eyes, saying, 'I like cold calling' (he really enjoys calling on students to answer questions in class), which feels quite friendly.

Today, let's talk about centralized exchanges and decentralized exchanges.
Friends with stock trading experience are quite familiar with exchanges.
Exchanges are essentially markets that bring together buyers and sellers to facilitate transactions. From the buyer's perspective, they place a buy order and eventually receive some stocks while spending some money; from the seller's perspective, they place a sell order and soon can exchange stock back for money. Although they may not know who the counterparty is during the transaction, as long as the price is right, a transaction can always be completed.

Hello friends, today we are going to talk about WLFI which is flying the banner of Trump.
What is WLFI
To talk about $WLFI, we must first talk about what WLF is. The full name of WLF is World Liberty Financial, which means "World Free Finance".
Why is it named so big? Its vision is to promote financial democracy and consolidate the status of the US dollar. The tone of this speech is very similar to when I go to the temple to pray, the wish I make in my heart is "I hope for world peace".
There is another important factor that has attracted so much attention to this project: Trump’s support. When you enter the official website homepage, there is a huge old man with his head tilted and his fist raised. In the lower right corner of each page of the white paper, there is also an old man with a frown, gray hair, but a firm gaze.

Hello everyone! Today we will talk about impermanent loss.
In English, it is called 'Impermanent Loss', which literally translates to 'temporary loss'.
Since I learned this term, I have particularly liked it. I think the person who translated this term is very clever, calling it 'impermanent', in this context of chasing highs and lows, yet it has such a clear and detached name.
What is impermanent loss?
Simply put: the market is fluctuating, and because you are providing liquidity to the market, you are passively selling high-value tokens while buying low-value tokens. Such passive trading leads to reduced returns compared to just holding coins.

Hello, friends! Today we will discuss the issue of decentralized lending.
The advent of the internet has accelerated the flow of information. The era when letters, newspapers, and books needed physical forms to convey information is over. The cost of wireless transmission has significantly decreased, eliminating the need to count words to send telegrams. In the past, traveling was slow, letters took time, and gossip only circulated locally. Now, with TikTok, gossip from all over the country is presented before you.
The reduction in information dissemination costs accelerates the spread of both quality and junk information. The good side is that acquiring knowledge has become significantly easier; high-quality courses are now readily available worldwide. The downside is that platforms like TikTok are so captivating that there’s little time left to attend public classes.
