Bitcoin: Under the Hood

Intermediate · 5 lessons · 0 complete

This course builds on Bitcoin Fundamentals to dig into the mechanics serious users and developers need: how wallets manage UTXOs, the scripting language behind every transaction, the SegWit and Taproot upgrades, the Lightning Network, and the fee market. It's for anyone who already understands double-spending, basic transactions, and mining, and wants to know what's really happening inside the protocol.
