✍️ Sample CBP Questions & Answers
1. A merchant accepting Bitcoin for a $50 item wants to minimize exposure to price swings. What is the best approach?
Using a payment processor to auto-convert Bitcoin to fiat at time of sale eliminates volatility risk for the merchant.
2. What is the scriptPubKey in a Bitcoin transaction output?
The scriptPubKey is the locking script placed on an output; to spend it, a matching scriptSig (or witness) must satisfy its conditions.
3. What is a stealth address in Bitcoin?
Stealth addresses allow the sender to derive a unique one-time address for the recipient, so each payment goes to a fresh address that only the recipient can find using their private key.
4. What is the key vulnerability addressed by requiring multiple confirmations before accepting a Bitcoin payment?
Each additional confirmation makes it exponentially harder for an attacker to rewrite history and reverse a transaction through a chain reorganization.
5. What is the risk of generating Bitcoin private keys using a weak random number generator?
Weak entropy means private keys can be reproduced by an attacker, allowing them to derive the corresponding public key and steal funds.
6. Which of the following best describes a 'selfish mining' attack?
In selfish mining, a pool secretly mines on its private chain and strategically releases blocks to waste competing miners' work, gaining more than its fair share of rewards.
