Create paths so one path funds another path.
|
||||
|
||||
Two accounts: sender and receiver.
|
||||
Two gateways: gw1 and gw2.
|
||||
Sender and receiver both have trust lines to the gateways.
|
||||
Sender has 2 gw1/USD and 4 gw2/USD.
|
||||
Sender has offer to exchange 2 gw1 for gw2 and gw2 for gw1 1-for-1.
|
||||
Paths are:
|
||||
1) GW1 -> [OB GW1/USD->GW2/USD] -> GW2
|
||||
2) GW2 -> [OB GW2/USD->GW1/USD] -> GW1
|
||||
|
||||
sender pays receiver 4 USD.
|
||||
Path 1:
|
||||
1) Sender exchanges 2 GW1/USD for 2 GW2/USD
|
||||
2) Old code: the 2 GW1/USD is available to sender
|
||||
New code: the 2 GW1/USD is not available until the
|
||||
end of the transaction.
|
||||
3) Receiver gets 2 GW2/USD
|
||||
Path 2:
|
||||
1) Old code: Sender exchanges 2 GW2/USD for 2 GW1/USD
|
||||
2) Old code: Receiver get 2 GW1
|
||||
2) New code: Path is dry because sender does not have any
|
||||
GW1 to spend until the end of the transaction.
