As an independent developer, these past two years have been a roller coaster with centralized services. Accounts are frozen at any moment, cloud service bills skyrocket like a rocket, and I've had enough of this life.

Previously, I had an AI Twitter bot project, with all data stored on AWS RDS. The monthly bills were terrifying, and traffic spikes made costs soar absurdly. The most heartbreaking part was that if Twitter's API policies changed or content was misjudged, the entire project and database could be frozen instantly. Years of accumulated training data and user interaction records could just disappear. It felt like playing on someone else's turf, always at risk of being kicked out.

Later, I realized one thing — I need to truly control my own project, rather than leaving my fate to a big company.

**My new architecture plan is as follows:**

The first part is core data storage. User preferences, conversation history, training datasets—these key pieces of information are packaged into data blocks and stored on a decentralized storage network. Using its erasure coding technology, paying tokens once grants permanent storage and ultra-strong availability guarantees. No more paying "protection fees" to cloud providers every month.

The second part is on-chain logic and state. The project's smart contracts are deployed on the SUI blockchain. Because SUI integrates tightly with decentralized storage ecosystems, data synchronization is lightning-fast. My points system and critical operation records are all on-chain, allowing users to verify at any time. This is unchangeable.

The third part is the front-end and computation layer. Using decentralized compute networks or lightweight VPSs to handle processing, keeping costs tightly controlled.

**How does it work? Not bragging.**

Costs have been reduced by over 80%, with even more savings in the long run. I can confidently say in project descriptions, "Our data is never lost, and logic is tamper-proof." User trust has significantly increased because they know the project is backed by solid technology, not just a company's word.

Most importantly, I finally feel like I truly own this project. It’s no longer an application parasitic on someone else's platform but exists and operates independently. This sense of autonomy is more valuable than just cutting costs.

If you're a developer also worried about the black-box costs of cloud services, consider this path. Blockchain isn’t just about price fluctuations; for independent entrepreneurs, it really can change the game.
