How it works

Alice wants to buy satoshis privately:

  1. Alice generates an avatar (AdequateAlice01) using her private random token.
  2. Alice stores safely the token in case she needs to recover AdequateAlice01 in the future.
  3. Alice makes a new order and locks a small hold invoice to publish it (maker bond).
  4. Bob wants to sell satoshis, sees Alice’s order in the book and takes it.
  5. Bob scans a small hold invoice as his taker bond. The contract is final.
  6. Bob posts the traded satoshis with a hold invoice. While Alice submits her payout invoice.
  7. On a private chat, Bob tells Alice how to send him fiat.
  8. Alice pays Bob, then they confirm the fiat has been sent and received.
  9. Bob’s trade hold invoice is charged and the satoshis are sent to Alice.
  10. Bob and Alice’s bonds return automatically, since they complied by the rules.
  11. The bonds would be charged (lost) in case of unilateral cancellation or cheating (lost dispute).

Original idea

The concept of a simple custody-minimized lightning exchange using hold invoices is heavily inspired in P2PLNBOT by @grunch
