Blockchain and Cryptocurrencies

Start with a blockchain overview

The Blockchain mind map introduces a blockchain as a growing ledger and describes its record of transactions. It is a useful starting point if you want an overview before working through more detailed terms. As you study, note the words you want to look at again, such as ledger and transaction.

The notes on the blockchain technology stack offer another way to organize your reading. They list layers from the network and data layers through to the application layer. Use the list alongside the overview map to keep track of the different layers named in the notes.

Move from maps to flashcards

The Off-chain Channel Networks mind map includes technical building blocks and applications, with references to Bitcoin, Ethereum and the Lightning Network. You can use it after the overview to explore a more specific area. The How Blockchain Will Change Organizations mind map looks at the technology in relation to companies, including how they are funded and managed.

For questions on technical terms, turn to Blockchain Engineering. Its flashcards ask about the longest chain, accumulated weight and compatibility in blockchain updates. Use the cards to identify terms you want to revisit in your notes or maps.

Test your understanding

Simulator EXIN Blockchain Foundations asks about public blockchains and nodes. The Simulador Blockchain quiz includes questions on consensus, mining and nodes. Try a quiz after studying the overview, then return to a map or flashcard deck for terms you want to study further.

Place the topic in the unit

Blockchain and Cryptocurrencies is a section of the Emerging Technologies unit in Computing and ICT. The page brings the resources together so you can move between an overview, specific networks and questions on technical concepts while studying this part of the unit. Choose a map and follow it with a quiz.
