What the CBP is and how it works

According to CryptoCurrency Certification Consortium, “The exam includes 75 multiple-choice and true/false questions covering each of the 33 topics listed below.”^[1]

The CBP is a knowledge certification from the CryptoCurrency Certification Consortium. It checks that you understand Bitcoin well enough to explain it and work with it in a professional setting. You take the exam online, from anywhere, at a time that suits you.

The exam has 75 multiple-choice and true/false questions, with a time limit of 20 minutes. The Consortium keeps the limit short on purpose so there is no time to look answers up, which means you need to know the material. You need a score of 70% to pass. When you pass, you get your certification ID and certificate straight away.

Once you pay the exam fee, you have 6 months from the date of purchase to take the exam. The purchase includes a retake. If you fail both your first attempt and the retake, you can pay to take the exam again.

The first certification lasts 2 years. To keep it, you renew every 2 years by passing the current version of the exam. The current fee, any eligibility conditions and the full topic list are on the official CBP page at cryptoconsortium.org. Check that page before you buy, because these details can change.

Worked examples: how to reason through CBP questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What happens if a Bitcoin user loses their private key?

1. They can recover it through the Bitcoin network
2. They permanently lose access to their Bitcoin
3. They can request a new key from the Bitcoin foundation
4. Their transactions get reversed

Answer: B. They permanently lose access to their Bitcoin

Explanation:

B is correct. A private key is what proves you control the coins at an address. Whoever holds the key can sign transactions, and without it nobody can. A is wrong because the network keeps no copy of your key and has no recovery process. Nodes only check signatures. C is wrong because Bitcoin has no central issuer or help desk that can create or replace keys. D is wrong because confirmed transactions are not reversed, and losing a key does not undo anything that has already happened. Rule to remember: in Bitcoin, controlling the funds means controlling the private key. That is why backups such as a seed phrase matter, and why people say "not your keys, not your coins."

Example 2

Question: What is a key compliance requirement for Bitcoin exchanges in the U.S.?

1. They must allow anonymous transactions
2. They must comply with Know Your Customer (KYC) regulations
3. They must operate without government oversight
4. They must fix Bitcoin prices to reduce volatility

Answer: B. They must comply with Know Your Customer (KYC) regulations

Explanation:

B is correct. U.S. Bitcoin exchanges are treated as financial businesses. Under Know Your Customer (KYC) rules they must verify who their customers are, and they also have anti-money-laundering duties. A is wrong because allowing anonymous accounts is the opposite of what KYC requires. C is wrong because exchanges work under government oversight, including registration and reporting duties. D is wrong because exchanges do not set or fix the price of Bitcoin. The price comes from trading between buyers and sellers. Rule to remember: the Bitcoin protocol does not ask anyone for their identity, but regulated businesses that handle customer money, such as exchanges, do. Expect questions that test this difference between the network and the companies built on top of it.

Example 3

Question: What is the core principle of Nakamoto Consensus that allows nodes to agree on the valid version of the blockchain in the event of a temporary fork?

1. The chain with the most transactions is considered valid.
2. The chain that was started by the earliest known miner is valid.
3. The first chain to be broadcast to a majority of nodes is valid.
4. The chain with the most accumulated Proof of Work (the longest chain) is considered valid.

Answer: D. The chain with the most accumulated Proof of Work (the longest chain) is considered valid.

Explanation:

D is correct. Under Nakamoto Consensus, when two valid versions of the chain compete, nodes follow the one with the most accumulated Proof of Work. People call this the longest chain rule, but what really counts is total work, not the number of blocks. A is wrong because the number of transactions tells you nothing about how much effort secures a chain. B is wrong because no "earliest miner" has authority, and any miner can extend any chain. C is wrong because the order in which chains are broadcast is not the test. A chain that nodes saw first can still be replaced when a competing chain builds up more work. Rule to remember: work decides. A temporary fork resolves when miners keep building on one branch until it carries more work, and the blocks on the other branch become stale.

How to use these practice tests

Start by reading the official CBP topic list on the Consortium's site so you know what the exam covers. Then take the practice set for each topic without a timer, starting with the basics: Bitcoin Basics and Cryptography, Wallets and Key Management and Blockchain and Transaction Mechanics. For every question you miss, write a short note on why the correct answer is right.

Next, move on to the network and policy topics: Mining and Consensus, Forks and Network Upgrades, Lightning Network and Layer 2, Security and Regulatory Issues and Legal, Compliance and Economics. Go back to your weak sets until you can answer without guessing.

In the last stage, practise under exam conditions. The real exam gives you 20 minutes for 75 questions, so you cannot work slowly through each one. Mix questions from several sets, set a timer and aim for quick recall. Treat 70% as the minimum, not the goal.

You have 6 months from purchase to take the exam, so book it once your timed scores stay steady. The exam is online, so pick a quiet place with a stable connection.
