Nunchuk CLI is a command line tool for agents to hold and spend bitcoin safely. Just paste this GitHub link to Hermes agent and as something like ‘create a bitcoin wallet and show me a QR code so I could send you some bitcoin’ or ‘create a 3-of-4 wallet. After 2 years, it becomes 2-of-4. After 5 years, it becomes 1-of-4‘.
Here is the link: https://github.com/nunchuk-io/nunchuk-cli

Week 4 was another great call on Discord where we answered the following questions:
1. How do scriptSig and scriptPubKey interact during validation? Why are they separated?
2. What are the steps a full node takes to validate a transaction before accepting it into the mempool?
3. Why did transaction malleability exist in legacy transactions, and how did SegWit fix it? Why is signature malleability a serious issue for higher-layer protocols like Lightning?
4. How are fees determined for a transaction? How does SegWit change the fee incentives for different parts of a transaction?
5. What constraints exist on coinbase transactions that don’t apply to normal transactions? How does the coinbase transaction commit to the block’s witness data?
6. What is the UTXO set? What role does it play in preventing double-spends?
7. What is a sighash flag? How do different sighash flags (e.g., SIGHASH_ALL, SIGHASH_NONE) change what is committed to?
8. What was Satoshi’s original intention for the sequence number and why is it considered insecure? What is the sequence number currently used for?
9. How do nLockTime, nSequence, OP_CHECKLOCKTIMEVERIFY, and OP_CHECKSEQUENCEVERIFY interact?
10. How do timelocks enable protocols like payment channels or vaults?
Next week we cover more. Stay tuned. @nprofile…73sx

Another great @npub15pk…wzej session with many bitcoin devs on the call. Here are questions we covered:
1. Explain the modulo operation.
2. Why must the modulus be prime for the set of integers modulo p to form a field? What breaks if we use a composite modulus instead?
3. What are the mathematical properties of a finite field? What are the field axioms?
4. Explain Fermat’s little theorem. How does it help compute inverses?
5. What are the properties of a mathematical group? What do we call a group that is commutative?
6. Explain how elliptic curve points form a group.
7. What is an elliptic curve? What are some of their practical uses in cryptography?
8. Explain elliptic curve point addition.
9. Explain the elliptic curve double-and-add algorithm.
10. What special function does scalar multiplication enable public key cryptography?

Good point, you are right. Vibe coding bitcoin wallets are extremely unsafe to hold real funds. It’s more of a gimmick rather than a super reliable wallet building tool. Great meme though!

It’s possible that this AI technology will increase productivity so much, that all these 10x more productive devs will innovate and drive prices down. We will get more for less, which is good in a deflationary global free market.
