Recent discussions about the $PING and $PAYAI projects have focused on their strategic adjustments. Although there hasn't been a rally in the short term, both are actively plugging leaks. $PING is enhancing consensus and empowerment through Launchpad, while $PAYAI plans to upgrade to an infrastructure protocol via token migration. These changes aim to adapt to the market environment and achieve long-term value, despite the short-term market response being unfavorable.

Elon Musk recently reposted an old post mentioning the DOGE-1 lunar mission paid for with Dogecoin, sparking heated discussions in the crypto community. Although the market reaction was muted and DOGE prices experienced slight fluctuations, this mission marks a true application of Dogecoin, with a planned launch in December 2025, representing a new attempt for cryptocurrency in the real world.

In the world of cryptocurrency, Meme coins are always the most unpredictable entities. No white paper, no technological innovation, and no practical application scenarios—just a meme, a phrase, or even a sticker, and within days, they can achieve a market cap of hundreds of millions of dollars. This sounds almost surreal, but it is indeed happening on the blockchain.
In October 2025, this frenzy sparked an incredible wave on BSC. Unlike the previous wild growth of Meme coins driven purely from the grassroots, this time the participants included not only the community but also direct involvement from a major exchange. From senior executives sending Chinese New Year blessings, to founders frequently engaging with users, to the official platform’s launch, the entire celebration seems chaotic but is actually a brilliant blend of cultural enthusiasm and capital strength.
This is not a sudden explosion but a perfect collision between top-down planning and grassroots passion. When a Meme coin filled with Chinese internet flavor suddenly emerges,

During the National Day holiday, the A-shares market was closed, but Meme coins surged wildly in the crypto circle, doubling in market cap in a short period and then crashing again. The market was chaotic, driven by emotions and capital, forming "emotional capital." The logic of traditional finance and the crypto market differs greatly. In the future, increased regulation and education are needed to prevent the market from becoming a tool for "scalping" retail investors.

A nearly 30-year-old HTTP status code suddenly becomes popular
In the HTTP protocol of 1997, there was a 402 status code, meaning "Payment Required." But at that time, it was impossible to implement, so it was left unused until now.
Until the maturity of encrypted stablecoins, L2 solutions reducing transfer costs, and AI Agents starting to run autonomously across the web requiring automatic payments—when these conditions came together, Coinbase picked up this "legacy button" and created the x402 protocol.
The core logic is straightforward: when AI or humans access paid content, there’s no need to register or jump to another page; just transfer USDC directly on the blockchain. It sounds simple, but behind it is a whole set of payment ecosystems being rebuilt.
How far has this ecosystem developed? Besides a bunch of Meme tokens speculating on concepts, what protocols, chains, and infrastructure are actually operational?
Protocol layer: teaching AI to "self-

In 1997, a code was embedded in the HTTP protocol: 402, meaning "Payment Required".
But this status code has never really been used since its inception. The reason is simple—there was no suitable online payment method at the time, so this function was shelved for almost thirty years.
Until now.
Stablecoins have matured, L2 has brought down payment costs, AI Agents have suddenly become popular, and the demand for micropayments has emerged. A leading exchange seized this opportunity and launched the x402 protocol: allowing AI or users to access paid content without registering an account or redirecting to another page, directly completing on-chain payments.
Sounds simple? In fact, there's an entire ecosystem being rebuilt behind the scenes.
Protocol layer: Teaching AI to "pay by itself"
x402 is not a single protocol, but rather a set of modular toolkits that solve three things: how AI
