Week 1 — Web3, blockchain, crypto assets and wallets
About 497 wordsAbout 2 min
8 parts 100 points Testnet only
Core question — why does Web3 exist, and how do blockchain assets and accounts actually work?
This is where Week 0's vocabulary turns into a working mental model, and the week you first touch a wallet. It ends with you having sent a real transaction on a test network and being able to explain what happened.

The arc
Each part answers the question the previous one leaves open.
Before you start
Part 7 needs a wallet — but not yet
You install one during that page, and it will be a fresh wallet holding testnet assets only. If you have not read Week 0 Part 4, read it before Part 6.
