I'm interested in learning about on chain and layer two projects that are trying to improve bitcoins privacy. Protocol changes, not wallets or mixers.
Todays privacy technique :
  • Disposable address
  • Whisper address
  • CoinJoin & PayJoin (coordinated & P2P)
  • CoinSwaps
  • PayNym
  • Coin Control
  • Loop in + Loop out (transfer between layers)
  • Using Taproot for multisig TX
  • Confidental TX (Liquid)
  • Lightning Onion Routing
TBD ? :
  • Teleport TX
  • BOLT 12 Blinded Path
  • Point Time Locked Contract
  • Taproot Channel (not widely developed)

MWEB and Confidential Transactions. Hopefully coming soon to Bitcoin after they activated on Litecoin and are proven to work very well.
