Questions About Blockchain Development?
We've worked with businesses across Taiwan since 2019, building everything from supply chain trackers to NFT platforms. Here are the questions we hear most often—and the honest answers we give.
Petteri Hakansson
Spent six years building Ethereum-based systems for manufacturing clients. Most of his projects start with "Can we actually do this?" conversations.
Solveig Brandvik
Writes smart contracts that handle real money and real inventory. She's debugged more contract failures than she'd like to remember.
Linnea Thorvaldsen
Connects blockchain systems to existing databases and ERPs. Her specialty is making new tech work with old systems without breaking anything.
Common Questions We Actually Get
How long does it actually take to build something?
A basic proof-of-concept usually takes 6-8 weeks. A production-ready system with proper testing? Three to five months is realistic. We had one client in Hsinchu who needed a supply chain tracker—took us four months from first meeting to launch in early 2025.
What if our team doesn't understand blockchain at all?
Most don't when they start. We spend the first two weeks just explaining how it works with your specific use case. One manufacturing client told us they finally understood it when we showed them their own inventory data on a test network.
Can you work with our existing databases?
Yes, and we do it constantly. Linnea spent three weeks last year connecting a blockchain system to a client's 15-year-old SQL database. It's not always pretty, but it works. Most projects need this kind of integration anyway.
What happens when something breaks?
We monitor everything and respond within four hours during business hours. Smart contracts are permanent once deployed, so we test extensively first. We also build admin functions that let you pause or adjust things if needed.
Do we need to understand Solidity or coding?
Not even a little. You need to understand your business problem. We handle all the technical stuff. Your job is telling us what you need the system to do—our job is making it happen.
How much does gas cost, and who pays for it?
Depends entirely on which blockchain you use. Ethereum is expensive—sometimes $50 per transaction during busy periods. Polygon or private networks might cost pennies. We help you pick the right one based on your budget and requirements.
Can we start small and expand later?
That's exactly what we recommend. Start with one process or department. Get comfortable with it. Then expand. A client in Taipei started with tracking 50 products. Six months later, they're tracking 5,000 across three warehouses.
What if regulations change or we need to modify things?
Smart contracts themselves can't change once deployed. But we build them with upgrade patterns and admin controls. Think of it like owning a building—you can't change the foundation, but you can renovate rooms as needed.
How do we know if blockchain is even right for us?
Honest answer? Sometimes it's not. If you need a simple database, use a database. Blockchain makes sense when you need transparency, multiple parties to trust the same data, or immutable records. We'll tell you if we think it's overkill for your situation.
Can you train our staff to maintain it?
We can train them to use it and understand it. Full maintenance usually requires blockchain expertise, which is why most clients prefer ongoing support contracts. We had one team in Taichung who wanted to learn everything—we spent two months training them in 2024.
How Projects Usually Work
Discovery Call
We spend an hour or two understanding your actual problem. Not selling anything—just figuring out if blockchain makes sense and what approach might work.
Proof of Concept
If it seems viable, we build a small working version with your real data. Takes about six weeks. You get to see exactly how it would function before committing to a full build.
Development and Testing
We build the full system, test it extensively, and deploy to a test network first. You'll see progress every two weeks and can request changes as we go.
Launch and Support
We deploy to the main network, train your team, and stick around for the inevitable questions and adjustments. Most clients keep us on retainer for ongoing support and updates.
