The Mechanics Trail

How the network works

Mechanics Trail is Bitcoin from the inside. It covers the shared record of every transaction, the wallets that prove what is yours, the nodes that enforce the rules, and the miners who secure it. From there it follows a single payment from start to finish. You may notice some overlap with the Foundations Trail. Mechanics returns to those topics and takes each one deeper.

What you walk away with

• What a blockchain is, and how it records history with no one in charge.
• What mining turns energy into, and why nodes, not miners, decide the rules.
• How you own Bitcoin without a bank, and what your keys control.
• What fees are and why they exist, and what finality means on the network.
