From ea1cd5b47f473eed60b3ed95853b053e9f686d69 Mon Sep 17 00:00:00 2001 From: Gavin Andresen Date: Wed, 18 Sep 2013 11:48:41 +1000 Subject: Remove CENT-output free transaction rule when relaying Remove the (relay/mempool) rule that all outputs of free transactions must be greater than 0.01 XBT. Dust spam is now taken care of by making dusty outputs non-standard. --- src/wallet.cpp | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/wallet.cpp') diff --git a/src/wallet.cpp b/src/wallet.cpp index 54ede12a5..daa5ba06f 100644 --- a/src/wallet.cpp +++ b/src/wallet.cpp @@ -1232,9 +1232,10 @@ bool CWallet::CreateTransaction(const vector >& vecSend, } int64 nChange = nValueIn - nValue - nFeeRet; - // if sub-cent change is required, the fee must be raised to at least nMinTxFee - // or until nChange becomes zero - // NOTE: this depends on the exact behaviour of GetMinFee + // The following if statement should be removed once enough miners + // have upgraded to the 0.9 GetMinFee() rules.
