Add a mass-pay JSON-RPC method, provided that the user interface requires a TX fee parameter (NOTE: zero is a valid TX fee)
I've got a (private so far) patch that creates mass-pay transactions. API is:
sendmulti <fromaccount> {address:amount,...} [minconf=1] [comment]
This code in CTransaction::AcceptToMemoryPool will need to change, too:
Code:
if (GetSigOpCount() > 2 || nSize < 100)
return error("AcceptToMemoryPool() : nonstandard transaction");
(a mass-pay transaction will have N+1 OP_CHECKSIGs in it, where N is the number of people being paid).return error("AcceptToMemoryPool() : nonstandard transaction");
Replacing in the stock client with something like:
Code:
if (GetSigOpCount() > 2) minFee += GetSigOpCount()*GetArgMoney("-masspayfee", CENT/100);
... seems like the right direction to go.BUT: I think a higher priority is figuring out how to deal with fees for the other two send methods.
