@ -101,5 +101,20 @@ Immediately refundable payments (2-of-3 can immediately cancel a payment) are
also possible but requires another payment in the opposite direction with the
R-value hashed twice (the R value becomes the H), but that's kind of annoying to
write... it's easier to just assume immediate refund can only occur if both
buyer+seller agree to cancel the payment immediately (otherwise it will wait
until the timeout).
Recipient+Sender agree to cancel the payment immediately (otherwise it will
wait until the timeout).
Also: THE ABOVE SCRIPT IS NOT THE MOST EFFICIENT SCRIPT POSSIBLE FOR THIS USE
CASE!!! This is to illustrate a similar conceptual use as current 2-of-3
multisig. Realistically, you want to do <EscrowPreimageR> *OR*
<SenderPreimageR> since the recipient will always redeem if they can. So the
hash code block would be instead:
OP_HASH160 <EscrowHash> OP_EQUAL
//Stack: <BobSig> <0> <RecipientPreimageR> <OP_1>
OP_SWAP
//Stack: <BobSig> <OP_1> <0>
OP_HASH160 <SenderHash> OP_EQUAL
//Stack: <BobSig> <OP_1> <OP_0>
OP_BOOLOR
//Stack: <BobSig> <OP_1>
OP_VERIFY
