Rhythm X Zhihu Hong Kong Event Recruitment Skills, Register Now for a Chance to Showcase Live
Six months ago, "How to Write Good Prompts" was the hottest topic in the group. Now, this question is clearly outdated. Replacing prompts is Skills.
The most apparent turning point, of course, was the emergence of OpenClaw.
Even though it could be said to be a copy, not an original of the agent, it truly brought the concept of the agent into the public eye, closer to the kind of AI you've seen in movies: has personality, can remember things, can plan, can truly get things done for you, not just answer your questions.
In the past, when everyone used AI, essentially they were using a very smart search engine—you ask, it answers, the next round starts again. The agent extended this line. It will actively advance tasks, detour obstacles, move on to the next step after completing one. The first time you see it actually handle a complete thing, you will have a strange feeling: this thing is really helping me get things done.
Then everyone started to think: how to make it more capable.
This is the real reason Skills took off. Not because Skills themselves are so novel, but because the agent made people seriously think about this issue for the first time. What Skills are doing is equipping the agent with specialized capabilities.
Why are Skills so important now?
An agent without Skills is like a smart but uneducated newbie. You ask him to do financial analysis, he will think, but his actions are slow, error-prone, many steps require you to guide him step by step. Skills are like him having learned the complete process of this field in advance—coming in, he can hit the ground running, without needing you to correct him repeatedly.
Now the most widely spread Skills in the community are concentrated in several directions: workflow automation, integrating operations that used to bounce back and forth between multiple tools into a chain that the agent can run on its own; injecting rules into professional domains, ensuring that the agent does not play arbitrarily when performing tasks with high accuracy requirements such as legal, medical, and financial tasks; personalization adaptation, tuning the agent to your most preferred way of working, remembering your preferences, language style, judgment criteria; of course, there is also a category of Skills related to money matters, such as trading.
The arbitrage opportunities on Polymarket, ordinary people cannot understand the odds, nor do they have time to watch trends and calculate spreads. But an agent equipped with specialized Skills can: monitor in real-time, identify deviations, decide whether to enter, the entire process does not require you to have any background knowledge of predicting the market.
The same goes for quantitative trading. In the past, this was the domain of investment banks and hedge funds, requiring writing strategy code, integrating with APIs, and monitoring backtest data. Now, someone has packaged the entire process into Skills, which can be installed on an agent to begin executing strategies on exchanges. The barrier to entry has shifted from "knowing programming and understanding finance" to "knowing how to install Skills."
This shift is not about making people lazy but about pushing the boundaries of capability outward.
Behind these demands is a common logic: people are starting to seriously regard the agent as a long-term collaborative partner rather than a disposable tool.
So, do you have any novel ideas that you would like to turn into your own agent's skill?
In the past, you had ideas, identified a market gap, but couldn't execute. You couldn't code, didn't have time to learn, outsourcing was expensive and slow, so that idea ended up rotting in your notes. Now things are different. Using vibe coding, you can directly mold your idea into a Skill—without building a website, without creating an app, without needing servers, without maintaining a team.
The underlying logic of this is: an agent will be a must-have for everyone. Your created Skills don't need you to acquire customers yourself; they naturally run on every agent that people are already using. The market is there, the channel is there, you just need to build something that others haven't.
Previously, between "I have a great idea" and "I have a working product," there was a technical team. Now, this distance has been compressed into a single weekend.
To showcase more good skills, BlockBeats and Zhihu partnered to host an event in Hong Kong on April 21 with the theme "Decrypting Web 4.0: When AI Agents Take Over On-chain Permissions."

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.
The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.
Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.
Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.
The trading process has been streamlined into five steps:
· Choose the trading asset
· Select long or short
· Input position size and leverage
· Confirm order details
· Confirm and open the position
The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.
Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:
· End-to-end encrypted private groups supporting up to 1024 members
· End-to-end encrypted voice communication
· One-click position sharing
· One-click trade copying
On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.
By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.
Mixin has also introduced a referral incentive system based on trading behavior:
· Users can join with an invite code
· Up to 60% of trading fees as referral rewards
· Incentive mechanism designed for long-term, sustainable earnings
This model aims to drive user-driven network expansion and organic growth.
Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:
· Separation of transaction account and asset storage
· User full control over assets
· Platform does not custody user funds
· Built-in privacy mechanisms to reduce data exposure
The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.
Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.
The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.
Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.
This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."
The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.
Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.
Its core capabilities include:
· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations
· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets
· Decentralization: achieving full user control over assets without relying on custodial intermediaries
· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication
Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
