Discussion Questions

Output Descriptors

  1. Are there any use cases for p2sh-wsh-p2pkh descriptors?
  2. What's about miniscript? Interactions with descriptors?

HD Wallets

  1. What is the difference between child and hardened child addresses?
  2. Why is the internal chain not visible outside of the wallet if it uses public derivation?

Coin Selection

  1. Is coin age ever a consideration for coin selection?
  2. Coin selection can expose a wallet by observing how the wallet selects its inputs, are there any efforts to standardize coin selection into a library of sorts so there's a standard?
