✍️ Sample CBP Questions & Answers
1. 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.
2. What role do private keys play in Bitcoin transactions?
Private keys are used to sign transactions, proving ownership and enabling the spending of Bitcoin securely.
3. What is 'routing' in the Lightning Network?
Routing in Lightning means payments can travel through multiple connected nodes to reach a recipient without a direct channel.
4. What is required to open a Lightning Network payment channel?
Opening a Lightning channel requires broadcasting an on-chain funding transaction that locks Bitcoin into a multi-signature address.
5. What is the Lightning Network primarily designed to solve?
The Lightning Network is a second-layer protocol designed to enable fast, low-cost Bitcoin transactions off-chain to address scalability limitations.
6. In asymmetric cryptography (also known as public-key cryptography), which key is kept secret and which is shared?
The core principle of asymmetric cryptography is the use of a key pair: a private key, which must be kept secret by the owner, and a public key, which can be freely distributed. Data encrypted with the public key can only be decrypted by the corresponding private key, and a signature created with the private key can be verified with the public key.
