Blockchain Guides
Blockchains are the core “plumbing” behind Bitcoin, Web3, and most of the crypto world — but most explanations are either full of jargon or skip the basics. This hub collects My Crypto Guide’s blockchain-focused guides in one place so you can understand how the technology works under the hood, without the headache.
How to Use This Hub
Start with the foundations to lock in a simple mental model of what a blockchain is and why people trust it. Then move into scaling (like Layer 2 networks) once the basics click. If you’re mostly here for real-world relevance, skip ahead to “Blockchain in the Real World” and come back to the deeper mechanics later.
The aim is understanding — not memorising jargon. Get the concept first.
Start Here: Blockchain Foundations
Begin with these beginner-friendly guides to understand what a blockchain is and why it matters.
- What Are Cryptocurrencies? (Plain-English Guide) – a simple foundation so blockchain terms make sense (coins, tokens, wallets, and why crypto exists at all).
- What Is Blockchain? Simple Guide – what the ledger is, how it stays consistent, and why it’s designed to be tamper-resistant.
- What Are Crypto dApps? (Plain-English Guide) – how decentralised apps use blockchains (and how they differ from normal apps).
Core Blockchain Concepts & Scaling
Once you’re comfortable with the basics, these guides explain what’s happening behind the scenes — especially how blockchains scale without turning into expensive, slow bottlenecks.
- What Are Layer 2 Blockchains? – how Layer 2 networks reduce fees and increase speed while leaning on the security of the base layer.
Blockchain in the Real World
See how blockchain technology is starting to replace or upgrade parts of the traditional financial system — especially around payments, settlement, and global transfers.
- Bitcoin vs Banks – how blockchain payment rails differ from bank accounts, and what that might mean long-term.
Related Topics & Next Steps
Once the blockchain layer makes sense, these hubs help you connect it to Bitcoin, security, markets, and the newer Web3 ecosystem.
- Bitcoin Guides – how Bitcoin uses blockchain, why the supply is capped, and why people treat it as “digital gold”.
- Crypto Security Guides – use wallets, private keys, and exchanges safely as you explore blockchain-based assets.
- Understanding Markets – cycles, behaviour, and long-term thinking (so you don’t learn markets the expensive way).
- AI & Web3 Guides – explore how Web3 apps are built on top of blockchains.
