About the Quiz:
A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers.
Blockchain can be seen as consisting of several layers:
- Infrastructure (hardware).
- Networking (node discovery, information propagation and verification).
- Consensus (proof of work, proof of stake).
- Data (blocks, transactions).
- Application (smart contracts/decentralized applications, if applicable).
