How Do Oracles Connect On-Chain and Off-Chain? Understanding the Chain of Risks Triggered by Incorrect Prices

In the Web3 world, smart contracts can automatically execute trades, lending, liquidations, and asset settlements according to preset rules.

But smart contracts have an important limitation: they cannot natively access real-world information outside the blockchain.

For example, a DeFi lending protocol needs to know the market price of ETH, an insurance contract may need weather or flight data, and some on-chain applications need exchange rates, match results, or other external event

Arbitrum now hosts 5,772 tokenized real-world assets, more than any other blockchain, ahead of Solana's 3,563 and Ethereum's 3,367.
That is more than 1.71 tokenized assets on Arbitrum for every 1 on Ethereum.

What is blockchain? Why is it considered important infrastructure for Web3?

In the Web3 world, blockchain is an important technological foundation for digital assets, smart contracts, and decentralized applications. It is used not only to record cryptocurrency transactions, but can also help multiple participants jointly maintain and verify data without a single central administrator.

First, what is blockchain?

Blockchain is a technology for organizing, verifying, and recording data according to specific rules. Transaction information is packaged into blocks, which are then linked to existi

What Are Stablecoins, and Why Are They Important Infrastructure for the Cryptocurrency Market?

In the cryptocurrency market, Bitcoin and Ethereum prices can fluctuate significantly, while stablecoins are usually pegged to fiat currencies such as the U.S. dollar, providing a relatively stable unit of account for trading, payments, and on-chain financial activities.

First, why are stablecoins important?

When investors need to temporarily reduce the impact of price volatility, they can consider exchanging their assets for stablecoins. However, stablecoins are not the same as bank deposits, and

$ERA Short-term bias is bullish, but a second push after a pullback is more likely than an immediate chase higher. Reasons: The Fear & Greed Index is only 28, placing the broader market in fear territory; BTC has not provided a strong catalyst, and capital tends to flow into high-beta, small-cap catch-up plays. ERA is a leading candidate, up 17.22% over 24h, with MA5>MA20 in a bullish alignment, a positive MACD histogram, and an intact structure. However, the current price of 0.0953 is already near the upper Bollinger Band at 0.09568, RSI at 66.1 is approaching overbought territory, and the f

The Real Threshold for AI Agents: Connecting Tools Is Easy, Reliable Collaboration Is Hard

AI agents are trying to connect to search engines, data platforms, office software, and blockchain applications. In theory, with the right interfaces, they can work across different tools to complete tasks. But the real question is: once the tools are connected, can they work together consistently and accurately?

First, interface interoperability does not mean business interoperability. Even if two platforms can exchange data, they may use different data formats, identity systems, and permission rules.

Cross-chain interoperability: Building a truly open Web3 digital ecosystem

Blockchain development is entering a new phase. Different networks are continually improving their performance, security mechanisms, and application ecosystems, but a practical question is also becoming increasingly apparent: when digital assets, users, and applications are distributed across different networks, how can they work together more seamlessly? Cross-chain interoperability is an important direction for guiding Web3 toward an open ecosystem.

First, interoperability can reduce barriers to the flow of informat

Come on, everyone! How could Jensen Huang possibly be removed? Would the shareholders agree? Don’t they know the premium and value Jensen Huang brings to Nvidia? The market has made it clear: just the possibility of Jensen Huang being removed has already sent Nvidia’s stock price here—and it’s the world’s largest company by market cap! Trump said he wouldn’t interfere in the removal of Nvidia’s CEO. The market should understand that if Jensen Huang isn’t removed, it’s the company’s own decision, not someone else’s. So think about it: would he really not interfere in something this big? #黄仁勋或遭罢

Why Can Trading Volume Suddenly Surge While the Price Doesn’t Necessarily Keep Rising?

In the cryptocurrency market, many traders see a surge in trading volume as a sign that a move is about to begin.

The price rises and trading volume increases, so they assume the trend is gaining strength.

But sometimes, trading volume continues to surge while the price starts moving sideways or even reverses and falls.

Why does this happen?

Because trading volume reflects trading activity, not a consensus about the market’s future direction.

Every trade has both a buyer and a seller. Rising trading vo

In BTC trading, how do you choose the right position size? Don’t let one mistake wipe out your entire account!

In BTC trading, many people devote a lot of effort to predicting market direction but overlook a question that directly affects their account’s survival: How much capital should they actually put in? Even if they predict the direction correctly, an oversized position could force them out early during sharp price swings.

So, how can you choose a position size scientifically?

First, don’t confuse your account balance with your actual position size. The amount of money in your account

This Bingtangcheng Fan Shao learned from Qiang, who used to take photos with people everywhere. Big-bellied Qiang at least actually went to conferences and shamelessly crashed photo ops. Fan Shao just photoshopped himself in—saved himself the plane ticket.

In the digital world, technological innovation is only the starting point. What truly determines how far a technology can go is whether it can solve real-world problems and create lasting value for people.

For ONEA, ecosystem development should not focus solely on the technology itself. It also needs to consider how the technology can be put into practice, connect with more participants, and maintain momentum in a constantly changing environment.

First, technological innovation needs a clear direction for application. Even a new idea with great potential must be explored, validated, and cont
