On April 10th, the first Xiaohongshu Hackathon Peak Competition, a creative marathon that transcends time and space, successfully concluded amidst heated discussions. At the event, the entire Harmony ecosystem showcased a particularly striking &#34;gravity&#34; that is highly certain. This gravity is reshaping developers' definitions of dividends through a brand new technological narrative.

Two developer teams made it to the finals of the Hackathon. The &#34;Hey! Star&#34; team had a brilliant idea—to help users install private servers into satellites. Their project ultimately won the &#34;HarmonyOS - Finding Treasure Developers&#34; award at the Xiaohongshu Hackathon. This cross-disciplinary team, born for the integration of software and hardware, includes a PhD in space materials from Peking University, a socially anxious geek from OPC, hardware entrepreneurs with over 100 million in revenue, and a cross-disciplinary blogger from Tsinghua and Peking University. The team completed two key demonstration loops on-site using HarmonyOS phones, leveraging the AR features of the HarmonyOS system and various built-in sensors to build a demo that directly interacts with the satellite control platform. Additionally, the developers created a dedicated app based on HarmonyOS, demonstrating the ability to control the satellite directly through the phone interface.

For a long time, competition in the mobile internet has entered a red ocean, with developers facing a dual squeeze of peak traffic and technological involution. However, in front of the HarmonyOS booth at this Xiaohongshu Hackathon, we witnessed a long-lost sense of excitement. The &#34;Treasure Archive&#34; showcased nine developers with surprisingly diverse backgrounds, including professional developers, students, and even a professional lawyer who, driven by a passion for legal logic and an understanding of HarmonyOS development tools, developed applications with significant social value.
This &#34;cross-disciplinary&#34; phenomenon actually reflects the system-level reduction of development thresholds by HarmonyOS. For developers, the first layer of meaning of dividends often refers to &#34;low-cost innovation possibilities.&#34;
In the past, achieving cross-end collaboration, high-level AI integration, or financial-grade privacy protection often required a mature technical team to spend months or even years. However, on the foundation of HarmonyOS, the Star Shield security architecture provides out-of-the-box APIs for anti-peeping and encrypted sharing through the Device Security Kit; the Distributed Soft Bus 4.0 directly reduces the latency of cross-device communication to the millisecond level
This philosophy of &#34;leaving the complexity to ourselves and handing the simplicity to developers&#34; is the core logic that attracts developers from diverse backgrounds to &#34;join the game&#34; with HarmonyOS.

Further digging reveals that the appeal of HarmonyOS also stems from its redefinition of &#34;application forms.&#34; In the peak showdown of the Xiaohongshu hackathon, what we saw was not just apps, but more creative practices based on the &#34;four major innovation themes.&#34;
For example, &#34;full-scenario integrated collaboration&#34; is no longer an illusory slogan, but is realized through meta-services (atomized services) with &#34;one-touch direct access&#34; and &#34;seamless flow.&#34; This means that developers' works are no longer confined to a single mobile screen but can freely shuttle between tablets, PCs, and even smart cockpits. This capability of full-scenario coverage essentially provides developers with a brand new traffic entry and interaction paradigm.
At the same time, the deep integration of AI has become the most significant dividend window in the Harmony ecosystem. In traditional development models, AI often exists as a plugin, whereas in HarmonyOS 6.0, AI is a native capability, allowing developers to expose application functions directly to the system, enabling Xiao Yi to suggest or execute services through voice commands. This &#34;AI actively seeking users&#34; model completely breaks the past passive logic of &#34;users searching for apps,&#34; providing mid to long-tail applications with opportunities for overtaking in curves.

Of course, the advancement of technology ultimately needs to be closed-looped through social value and commercial returns. The upcoming Huawei Developer Conference (HDC) and the &#34;2026 HarmonyOS Innovation Competition · Geek Track&#34; with a prize pool exceeding 680,000 yuan will be the battlefield for developers to truly showcase their talents. The cash prize of up to 150,000 yuan for the first prize in the 2026 HarmonyOS Innovation Competition · Geek Track is not only a recognition of coding ability but also an investment in the commercial vision of developers.

Looking back at the excellent cases from the 2025 HDC Geek Marathon, whether it is &#34;Smart Navigation&#34; providing precise navigation for visually impaired individuals or &#34;Dragonfly Radio&#34; redefining content distribution using meta-service characteristics, both confirm the &#34;inclusive&#34; nature of the Harmony ecosystem. These developers come from universities, startups, and various industries, utilizing Harmony's distributed hardware virtualization and AI image editing capabilities to address real pain points in professional fields and daily life, allowing the warmth of technology to be embedded in the seamless collaboration of these devices.

From the enthusiasm of this Xiaohongshu hackathon peak competition, we can clearly foresee that an &#34;all-scenario innovation era&#34; led by Harmony developers is accelerating. When an operating system can provide developers with a &#34;scaffold&#34; from four dimensions: security, collaboration, AI, and spatial interaction, the dividends it generates are no longer short-term subsidies but long-term growth certainty. In an era of stock competition, this certainty is more precious than any traffic support
