Adding to wallet

  • Wallet adds txs naively, we need to support adding txs in order but not in mempool
  • Allow recipient adding parent
  • No privacy fingerprint if we give parent or any ancestors, but no siblings
  • getdata must be for the inv we sent
  • we have GetAncestors API to whitelist all getdata for all inputs
  • we need a txgraph of the private broadcast queue
  • Up from the tx we broadcast, pick from mempool all ancestors to add to private broadcast as well, then start with child and parent

Package relay

  • 1p1c
  • we get for free with above

Persistence

  • can't remove based on mempool checks for the above
  • write to a file every add of a new tx
  • on startup, read the file and add txs to private broadcast
  • debatable if we need it

Decoys

  • every hour or so pick one of your last txs and private broadcast them
