Build Real Blockchain Skills Through Hands-On Practice
Most people think blockchain is some mysterious technology only computer science graduates can understand. That's not true. Our program breaks down complex concepts into workable pieces you can actually use. We focus on real applications rather than abstract theory.
Starting October 2025, we're running a structured six-month program that covers distributed systems, consensus mechanisms, and smart contract development. You'll work with actual blockchain networks — not simulations.

Common Roadblocks and How We Address Them
Learning blockchain isn't just about reading documentation. People run into specific obstacles. Here's what we see most often and how our approach helps.
Confusing Cryptography
Hash functions, digital signatures, and encryption feel overwhelming without mathematical background.
Most courses assume prior knowledge of cryptographic principles or skip practical implementation entirely.
We demonstrate each concept with working code examples. You'll implement basic hashing before moving to advanced topics.
Setting Up Environments
Getting development tools configured correctly takes hours and causes frustration before any actual learning begins.
Documentation is scattered across different platforms with version conflicts and unclear instructions.
We provide pre-configured virtual machines and step-by-step setup guides tested on multiple operating systems.
Understanding Consensus
Proof of Work, Proof of Stake, and Byzantine fault tolerance sound like academic theories rather than practical tools.
Abstract explanations don't connect to real network behavior or why certain approaches work better than others.
You'll build a simple consensus mechanism from scratch and see exactly where different approaches succeed or fail.
Debugging Smart Contracts
When contract code fails, error messages are cryptic and debugging tools are limited compared to traditional development.
Testing blockchain applications requires understanding gas costs, transaction ordering, and state management simultaneously.
Our curriculum includes dedicated debugging sessions where you fix intentionally broken contracts using professional workflows.
Security Vulnerabilities
Common exploits like reentrancy attacks or integer overflow seem obvious in hindsight but are easy to miss while coding.
Security considerations are often taught separately from development rather than integrated into the coding process.
Every module includes security review exercises where you identify and fix vulnerabilities in sample contracts.
Real Network Deployment
Moving from local testing to actual blockchain networks involves new considerations around transaction costs and network latency.
Tutorials focus on localhost testing but don't prepare students for production deployment challenges.
Final projects deploy to test networks with real monitoring and maintenance requirements, not just local environments.
Core Components Connected Through Practice
Everything in blockchain development connects to everything else. Rather than teaching topics in isolation, we show you how these pieces work together in real applications.
Distributed Systems Architecture
Network Protocol Implementation
You'll build peer-to-peer communication between nodes using actual networking libraries. This covers message propagation, peer discovery, and handling network partitions. By month three, you'll understand exactly how blockchain nodes talk to each other and why certain design choices matter for network reliability.
Transaction Pool Management
Before transactions make it into blocks, they sit in a mempool. We'll show you how nodes prioritize transactions, handle double-spend attempts, and manage memory constraints. This connects directly to how miners or validators select transactions and why gas pricing works the way it does.
State Synchronization Methods
When new nodes join a network, they need to catch up with current state. You'll implement different sync strategies — full sync, fast sync, and light client approaches. Understanding this helps you design applications that work with various node configurations and performance requirements.
Smart Contract Execution Environment
Smart contracts run in virtual machines with specific constraints. We go deep into how the Ethereum Virtual Machine processes bytecode, manages gas metering, and handles storage. You'll write contracts that optimize for these constraints rather than fighting against them.
Cryptographic Verification Chains
Every block links to the previous one through cryptographic hashes. But there's more to it — Merkle trees, signature verification, and key management all play roles. You'll implement these verification systems and see exactly how they prevent tampering and enable lightweight proof systems.
Who You'll Learn From
Our instructors work on blockchain projects during the day and teach what they're actually using. No theoretical lectures from people who haven't written production code in years.
Torben Eskildsen
Torben spent four years building consensus mechanisms for a Layer 2 scaling solution. He'll walk you through distributed systems design with examples from actual production challenges he's solved. His debugging sessions are known for being brutally honest about what works and what doesn't.
Silje Dalgaard
Before teaching, Silje worked as a smart contract auditor finding vulnerabilities in DeFi protocols. She brings real audit reports into class and shows you exactly what security issues look like in production code. Her approach is practical — you'll learn to think like an attacker while writing defensive code.
Petra Lindqvist
Petra builds full-stack blockchain applications for enterprise clients in Taiwan. She covers how to integrate smart contracts with conventional web applications, handle private key management, and design user experiences that make sense for non-technical users. Her projects section focuses on deployment and maintenance, not just initial development.
