Why Aren’t DeFi Prices Determined by the Blockchain Itself? Understanding the Risks Behind Oracles

In the DeFi world, whether a loan can be completed successfully, whether a collateral asset will be liquidated, or even whether a stablecoin protocol can operate normally may all be affected by price data.

But the blockchain itself cannot directly know the real-world price of BTC, foreign exchange rates, or changes in the weather.

So how do smart contracts obtain this information?

The answer is: an oracle (Oracle).

It is essential infrastructure connecting blockchains with external data, and

Wait, what??? Gemini sold its UK and European businesses as a package for less than $10 million???
On November 12, it emerged that the Winklevoss brothers' @Gemini had sold its UK and European businesses to stablecoin payments company @KASTxyz for less than $10 million, with the buyer reportedly mainly after the local licenses.
Looking back at the timeline: In February this year, Gemini announced it was exiting the UK, EU, and Australia and laying off about 25% of its global workforce. Its own estimated restructuring costs were around $11 million.

The growth of an ecosystem often begins with curiosity, develops through continuous learning, and ultimately takes shape through the actions of each individual.

In today’s rapidly advancing digital world, understanding a project should go beyond simply reading its introduction or following its updates. More importantly, it means understanding how it works, where it is headed, and what real-world problems it might solve. Only by developing our own understanding can we assess an ecosystem’s value more rationally and find ways to participate that suit us.

ETH has dropped excessively this round, nearly breaking below 2000.
ETH is now trading below all moving averages, with a bearish alignment.
The descending channel remains intact, showing a typical consolidation during a downtrend.
The high-volume decline shows strong bearish pressure. The breakdown is valid, with no buyers stepping in to buy the dip. The move is driven only by shorts taking profits in the short term, with no bullish support.
Trading recommendation: Short on a rebound to 2050–2080.
Stop loss above 2110.
Target: around the previous low near 2010.

The Next Step in AI and Web3 Integration: Turning Complex Technology into a Simple Experience

When people talk about Web3, they often focus on blockchain performance, transaction speed, the degree of decentralization, and technical architecture. But for ordinary users, what ultimately determines whether a technology can be widely adopted is often not how complex it is under the hood, but how easy it is to use.

Imagine users being able to complete a cross-platform task without needing to understand the differences between blockchains, repeatedly search for data, or switch between multiple app

Why Can Even an Airdrop That Looks Legitimate Be a Scam? Building an Airdrop Security Checklist from Phishing Links to Malicious Approvals

In the Web3 world, airdrops have always been one way for users to engage with new projects.

Some projects distribute tokens through airdrops, reward early users, or expand community participation. At the same time, scammers exploit people’s desire to get free tokens by creating campaigns that look completely legitimate.

They may have polished campaign pages, fake official accounts, seemingly authentic task lists, and even misuse the names and logos of we

The true value of AI agents is not having more information, but making information valuable

In the digital economy, we have never lacked information. Industry news, market data, community discussions, expert opinions, and on-chain records continue to grow every day. The real challenge is identifying important signals from this vast amount of information and turning them into useful decisions.

This is exactly why AI agents deserve attention.

First, integrating information is only the starting point; understanding the relationships between pieces of information is what matters. A single news

The G7 foreign ministers issued another statement in Paris, this time without even sanctions or military deployments—who are they trying to scare with just a piece of paper!
Honestly, I’ve heard “opposing unilateral changes to the status quo by force or coercion” so many times I can recite it by heart. They issue it every year, every time, then carry on as usual
The statement says China’s activities in waters east of Taiwan threaten regional stability, freedom of navigation, and the safety of international shipping, but it can’t come up with a single figure showing which shipping route or vess

SOL is bottoming out in a low-level range, with moving averages continuing to cap prices and weakness persisting

Now at $83.05 (-0.05%), with the 24H range narrowing to 82.19-85.85. It has risen from the previous low of 81.34 but remains in the danger zone. The 4H moving averages are in bearish alignment (EMA7:83.52 / EMA20:84.79 / EMA60:88.66), and the current price is hugging just below EMA7. A move above 83.52 would mark preliminary stabilization; only a break above 84.79 would signal a shift to strength. Down 14.21% over 7 days and 22.87% over 30 days, the overall
