Summary
Go through the brief summary of the chapter in this lesson.
We'll cover the following
Key takeaways
The Bitcoin system is an electronic payment system that relies entirely on
- Public-key cryptography
- Digital signatures
- Hash functions
As shown, the transactions create a chain of digital signatures, with each transaction permanently saved in blocks that are subsequently appended to the blockchain to create a tamper-proof ledger of transactions.
What’s next?
In the following lessons, we’ll learn the basics of quantum computation and its effects on existing cryptographic techniques and blockchain technology. Furthermore, we’ll learn about the consequences of a broken cryptographic primitive.
