I spent three years building infrastructure for a DeFi protocol before teaching. And the gap between what courses teach and what you actually need to know? Huge.
Most programs rush you through building tokens and NFT marketplaces. Sure, those are fun projects. But when you join a real team, nobody cares if you can deploy a basic ERC-20 token. They care if you understand why transaction ordering matters, or how to debug gas estimation failures.
The Skills That Actually Transfer
Here's what I wish someone had taught me early on. Not the flashy stuff — the foundations that make everything else make sense.
State Management
How blockchains handle data persistence differently than traditional databases, and why that changes everything about application design.
Event Architecture
Reading events from the blockchain is how real applications work. But most tutorials skip this entirely.
Testing Strategies
Unit tests are fine. But integration testing with actual network conditions? That's where you catch real problems.
Error Handling
Blockchain errors are cryptic. Learning to debug them efficiently saves hours of frustration later.
The breakthrough moment for most students isn't writing their first smart contract. It's when they finally understand why decentralization creates specific tradeoffs — and how to work within those constraints instead of fighting them.
What We Changed in Our Curriculum
After watching dozens of students struggle with the same concepts, we restructured everything. Instead of starting with Solidity syntax, we spend the first two weeks just reading existing contracts and predicting what they'll do.
Sounds boring, right? But it works. Because once you can read and understand code that's already running on mainnet, writing your own becomes way less intimidating. You've seen the patterns. You understand the common approaches.
We also stopped treating security as a separate topic you learn at the end. Every concept now includes "here's how this can go wrong" alongside the basics. Because in blockchain, mistakes cost real money.
The Taiwan Context
Teaching in Taipei adds interesting dimensions. Many students come from traditional finance or manufacturing backgrounds — they understand risk management and complex systems, just not in a blockchain context yet.
That experience actually helps. They ask better questions about failure scenarios and edge cases than fresh CS graduates sometimes do. The challenge is bridging terminology, not explaining concepts.
