# Particl Atomic Swap - Proof of concept
|
||||
|
||||
## Overview
|
||||
|
||||
Simple atomic swap experiment, doesn't have many interesting features yet.
|
||||
Not ready for real world use.
|
||||
|
||||
Uses Particl secure messaging and Decred style atomic swaps.
|
||||
|
||||
The Particl node is used to hold the keys and sign for the swap transactions.
|
||||
Other nodes can be run in pruned mode.
|
||||
A node must be run for each coin type traded.
|
||||
In the future it should be possible to use data from explorers instead of running a node.
|
||||
|
||||
## Currently a work in progress
|
||||
|
||||
Not ready for real-world use.
|
||||
|
||||
Features still required (of many):
|
||||
- Cached addresses must be regenerated after use.
|
||||
- Option to lookup data from public explorers / nodes.
|
||||
- Load active bids from db at startup
|
||||
- Ability to swap coin-types without running nodes for all coin-types
|
||||
- More swap protocols
|
||||
- Method to load mnemonic into Particl.
|
||||
|
||||
|
||||
## Seller first protocol:
|
||||
|
||||
Seller sends the 1st transaction.
|
||||
|
||||
1. Seller posts offer.
|
||||
- smsg from seller to network
|
||||
coin-from
|
||||
coin-to
|
||||
amount-from
|
||||
rate
|
||||
min-amount
|
||||
time-valid
|
||||
|
||||
2. Buyer posts bid:
|
||||
- smsg from buyer to seller
|
||||
offerid
|
||||
amount
|
||||
proof-of-funds
|
||||
address_to_buyer
|
||||
time-valid
|
||||
|
||||
3. Seller accepts bid:
|
||||
- verifies proof-of-funds
|
||||
- generates secret
|
||||
- submits initiate tx to coin-from network
|
||||
- smsg from seller to buyer
|
||||
txid
|
||||
initiatescript (includes pkhash_to_seller as the pkhash_refund)
|
||||
|
||||
4. Buyer participates:
|
||||
- inspects initiate tx in coin-from network
|
||||
- submits participate tx in coin-to network
|
||||
|
||||
5. Seller redeems:
|
||||
- constructs participatescript
|
||||
- inspects participate tx in coin-to network
|
||||
- redeems from participate tx revealing secret
|
||||
|
||||
6. Buyer redeems:
|
||||
- scans coin-to network for seller-redeem tx
|
||||
- redeems from initiate tx with revealed secret
