- √ Private keys can be stored offline.
- × Transaction fees are dynamic, not fixed at 1 BTC.
- √ Open-source code allows derivative cryptocurrencies.
Section 3: Key Terminology (20 Points)
1. Hash Function
Definition: A cryptographic process converting input into a fixed-length, irreversible output. Critical for blockchain security.
2. Public Key
Usage: Encrypts data for secure transmission; paired with a private key for decryption.
4. Digital Signature
Purpose: Authenticates message integrity via asymmetric encryption (e.g., Bitcoin transactions).
Section 4: Short Essays (40 Points)
1. Bitcoin’s Creation Principle
Bitcoin mining solves complex mathematical problems to discover unique "nonces" (solutions), generating new BTC. The protocol caps supply at 21 million through halving block rewards (currently 6.25 BTC per block).
2. Bitcoin vs. Blockchain
Blockchain is the underlying ledger technology enabling Bitcoin’s decentralized transactions. While Bitcoin popularized blockchain, the tech now supports smart contracts, supply chain tracking, and more.
FAQ: Bitcoin Essentials
Q1: Can Bitcoin be mined indefinitely?
A: No. The final BTC will be mined circa 2140, after which miners earn fees only.
Q2: Is blockchain only for cryptocurrencies?
A: No. Industries use blockchain for transparent record-keeping (e.g., healthcare, voting).
Q3: How secure is Bitcoin?
A: Extremely. Its PoW consensus requires immense computational power to alter transactions.
