Introduction x402 is an open payment standard launched in 2025, aimed at officially activating the HTTP 402 status code and transforming it into an internet-native payment mechanism. A technical standard jointly promoted by the internet infrastructure company Cloudflare and the cryptocurrency exchange Coinbase. Compared to traditional models that require creating accounts, binding credit cards, or pre-loading funds, x402 embeds payment requests directly into HTTP responses, allowing clients (whether human, robot, or AI agent) to automatically recognize payment information and complete transactions.
Google Labs Launches a Brand New Experimental Browser Disco, Featuring Gemini 3
Disco is currently an experimental browser independent of Chrome, used to test the new concept of GenTabs.
GenTab can be understood as "AI-generated mini-applications" that automatically create interactive interfaces based on your search intent, chat history, and open tabs, instead of just providing you with a bunch of links or a summary.
For example, when planning a trip to Japan, Disco will read the webpages of attractions and food you have opened and directly generate an interactive map and itinerary planner in the browser.
Disco is currently just an early experiment from Google Labs and has opened a waiting list.
The core of blockchain is verifiable And complete transparency is a forced compromise that comes with it
Thus MEV, front-running, and other concepts were born
If traditional finance is to fully integrate with blockchain, addressing privacy issues is essential
First generation: Mixing coins: Tornado represents a whirlwind, mainly solving the privacy of asset transfer Second generation: ZK, mainly solving the privacy of proof, off-chain proof, on-chain verification Third generation: MCP, data sharding, but currently only applied in key management that matches well
Blockchain is just a tool for traditional finance Using the characteristics of 'blockchain' Such as transparency, real-time settlement To trade other financial products
The native assets of blockchain Are few and far between
On December 10th (Wednesday), the Federal Reserve (Fed) will hold its last annual FOMC meeting.
Core Event: The market widely expects the Federal Reserve to announce a rate cut of 25 basis points, but the real focus will be on Powell's press conference after the meeting (3:30 AM Beijing time on Thursday).
Key Highlights and Significance:
This meeting is seen as a critical moment that will determine the macroeconomic direction for 2026. Liquidity Expectations: The market is closely watching whether the Federal Reserve will initiate a monthly $45 billion Treasury bond purchase program (referred to as 'reserve management operations'), which is viewed as a disguised way to inject new liquidity into the market.
Politicization of Policy: This meeting faces rare internal disagreements (the highest number of dissenting votes since 2019), marking a shift in monetary policy formulation that is being reshaped by 'political' divisions.
Regulatory Resonance: This macro monetary policy juncture coincides with SEC Chairman Paul Atkins explicitly stating that ICOs will be transferred to CFTC regulation. This means that the 'expectations of monetary easing' and 'structural rollbacks in regulation' are colliding within the same time window, directly impacting the pricing logic of silver and cryptocurrency assets.
As of December 2025, silver prices are at a historically high moment, with futures prices breaking into the $56-$57/ounce range, and the cumulative annual increase astonishingly reaching about 90%, significantly outperforming gold.
The immediate effect of the sharp rise is that there is not enough spot silver available in the market.
Those who previously shorted silver are forced to buy back at high prices (also known as "short squeeze"), and warehouses around the world are urgently reallocating supplies to respond.
In terms of long-term impact, expensive silver puts immense pressure on downstream manufacturers producing photovoltaic panels and AI hardware, as raw material costs soar.
However, this has also made the market recognize a reality: silver is a crucial "green industrial necessity," and in the long run, there simply isn't enough.
The U.S. Securities and Exchange Commission (SEC) has officially concluded its two-year investigation into Ondo Finance, a leading company in the tokenization of real-world assets (RWA), without bringing any charges.
The SEC's investigation began in October 2023 (during the Biden administration) and focused on whether the tokenization of U.S. Treasury bonds, represented by $ONDO , violated federal securities laws, as well as whether its governance token $ONDO qualified as an unregistered security.
Final outcome: Ondo Finance received formal notification at the end of November 2025, confirming that the investigation has been closed and that the SEC does not recommend any enforcement actions.
Recently, Ondo acquired a licensed broker-dealer and ATS (Alternative Trading System) operator, Oasis Pro, which has provided it with a full compliance license to issue and trade tokenized securities in the U.S.
It is a trading execution model used to match buy orders (Bids) and sell orders (Asks).
In a centralized ledger or database, the system automatically matches the trades of buyers and sellers based on price priority and time priority principles.
It is also the standard trading model used by centralized exchanges such as Nasdaq, New York Stock Exchange (NYSE), and Binance.
Not based on Uniswap-style AMM (Automated Market Maker), but adopts an order book model similar to Binance and Kraken, supporting spot and perpetual contracts (Perps)

Unified Margin Account: All assets (spot, stablecoins, unrealized P&L) are in a single unified account pool
High-Performance CLOB (Central Limit Order Book): Achieves a matching engine speed of 5-15ms
NLP (Nado Liquidity Provider) - Passive Market Making: Similar to GMX's liquidity pool model
What is the essential difference between current DEX, which are basically CLMM (Concentrated Liquidity Market Makers), and the original AMM (Automated Market Makers)?
In simple terms, it is the different positions of capital placement.
1. Traditional AMM (like Uniswap V2): Capital is dispersed
The system forces your capital to be evenly spread across all price ranges from '0 to infinity'.
Problem: No matter what the current market price is, a significant portion of your capital is actually idle and not participating in trades, resulting in very low fee earnings.
2. CLMM (like Uniswap V3 / Orca): Capital is concentrated
It allows you to manually set a specific price range (for example, between 200U and 220U for SOL). You only place your capital within this range.
Advantage: Since capital is concentrated near the prices where trades actually occur, your capital efficiency can increase by tens or even hundreds of times, resulting in higher fee income under the same principal amount.
But there is a cost to this:
CLMM requires you to constantly monitor the prices. Once the market price moves out of your set range, your capital will stop working (no longer earning fees) and may even face a more direct impermanent loss risk compared to traditional AMM.
A Simple Understanding of the Largest Decentralized Exchange (DEX) on the Solana Blockchain: HumidiFI
—— Data Strong
1. The largest DEX on Solana, with a daily trading volume exceeding $1 billion ($1B) 2. The spot DEX trading volume on Solana is approximately 35%. 3. Launched for less than 6 months, at certain times accounting for over 50% of the total trading volume of Solana DEX 4. In terms of SOL-USD spot trading volume, it has surpassed Binance
—— Problems Solved
Limitations of AMM
1. Static pricing 2. Low capital efficiency — price curve distribution is wide 3. Slippage and spreads 4. No user segmentation, bots, real users, large players, etc. 5. LPs are prone to impermanent loss
—— Solutions
1. Off-chain computation of complex content, such as high-frequency trading 2. On-chain bookkeeping and token confirmation, non-custodial 3. Dynamic pricing, off-chain oracle flow + predictive pricing (this is pending, feel it needs deeper observation for any loopholes) 4. Dynamic inventory balancing 5. MEV resistance
Jason Calacanis is a well-known tech investor and a long-time critic of Tether.
He has warned on multiple occasions (such as on the 'All-In Podcast' or 'This Week in Startups') about the risks of using Bitcoin as a reserve asset.
He has stated that if the price of Bitcoin plummets, companies like Tether may be forced to sell Bitcoin to maintain liquidity, which could trigger a 'death spiral'.
So it is possible that there were relevant comments in the podcast, but they are not factual.
As of the third quarter of 2025, Tether's Bitcoin holdings reportedly approached 11,000 (approximately 109,410 BTC), valued at over $10 billion.
Dark Pool, in essence, is a trading venue that hides the order book.
In regular exchanges, how much money you offer and how much you buy can be seen by the whole world. In a dark pool, after you submit an order, the system secretly matches it in the background, and no information is displayed externally before the transaction is completed.
The significance of its existence:
In traditional finance, for the sake of 'stability' Large investors (Whales) need to sell huge assets. If they place orders directly on the open market, it would instantly trigger panic selling, leading to poor prices.
A dark pool allows them to quietly complete their transactions without disturbing the market.
In Web3, for the sake of 'protection' On-chain data is too transparent. Once trading intentions are broadcast, they can be targeted by arbitrage bots (MEV Bots), leading to front-running or squeeze attacks.
Web3 dark pools use technologies like zero-knowledge proofs (ZKP) to encrypt trading intentions at the code level, making it so that bots are 'blind' to them, thus protecting profits.
