Inside Module 1

Five lessons. Everything you need to know before touching a hardware wallet.

Module 1 builds the conceptual foundation that every other security decision rests on. You can't protect what you don't understand.

Lesson 1 of 5
What Is Bitcoin & Why Does Security Matter?
Bitcoin removes the middleman — which means it removes every protection the middleman provides. Understanding what's actually at stake is the starting point for everything else.
Bitcoin vs. banks Trustless systems Self-custody risk
Lesson 2 of 5
Blocks, Mining & the Blockchain
How does Bitcoin actually reach consensus with no central authority? This lesson explains Proof of Work, block structure, and why altering any confirmed transaction is computationally impossible.

Lesson 3 of 5
Private Keys, Wallets & Seed Phrases
The most important lesson in the module. Your private key is not a password — it is cryptographic proof of ownership. Lose it and your Bitcoin is gone. Give it away and your Bitcoin is stolen.
Private & public keys Seed phrases HD wallets
Lesson 4 of 5
Transactions, UTXOs & the Mempool
How Bitcoin actually moves — from your wallet to the network, through the mempool, into a confirmed block. Includes change addresses, transaction fees, and how to use a block explorer.
UTXOs Change addresses Fee priority
Lesson 5 of 5
Bitcoin's Fixed Supply & Why It Matters
21 million. Hard coded. Unchangeable. This lesson explains how the block subsidy and halving cycle make Bitcoin the hardest money ever created — and why that makes security non-negotiable.

This is just the beginning. The full course goes deep.

Module 1 gives you the foundation. The remaining five modules walk you through every practical step of securing your Bitcoin.

Module 2
Why Bitcoin Over Crypto
What makes Bitcoin categorically different from every other digital asset — and why altcoin claims fall apart under scrutiny.
Module 3
Running a Full Node
Install, configure, and use your own Bitcoin node — the only way to verify transactions without trusting anyone.
Module 4
Cold Storage Setup
Hands-on hardware wallet setup, multisig vaults, seed phrase backup — this is where the rubber meets the road.
Module 5
Privacy Strategies
Chain analysis, CoinJoin, UTXO management, KYC-free acquisition, and Tor — protect your financial privacy.
Module 6
Long-Term Security Strategy
Threat modelling, inheritance planning, OPSEC, key distribution, and the habits that keep your Bitcoin safe for decades. The module that ties everything together.
