Which lesson comes next?

  • What is Bitcoin actually doing?

    Bitcoin lets people send digital money without a bank handling the payment. Start by separating the payment record, the rules and the keys that approve spending.

  • What do Bitcoin units and supply mean?

    A bitcoin can be divided into smaller amounts. The supply rules limit new creation, but neither divisibility nor a supply cap promises a market price.

  • What can you share and what stays secret?

    Share a receiving address when someone needs a payment destination. Keep private keys and recovery words secret because they can give access to spending.

  • How can you follow a Bitcoin payment?

    A payment is approved, shared with the network and checked before a block can record it. A waiting payment and a confirmed payment are different states.

  • What does a Bitcoin account promise?

    A service balance is a claim within that service's account system. Understand who holds the keys, what withdrawals allow and which risks remain outside Bitcoin's rules.

  • How can you tell digital assets apart?

    Start with an asset's full name, network and rules. Bitcoin, fork coins, stablecoins and project family descriptions are different things even when names sound similar.

How could you use the course?
