From b33d1f5ee512da5719b793b3867f75f1eea5cf52 Mon Sep 17 00:00:00 2001 From: Gavin Andresen Date: Tue, 27 May 2014 15:44:57 -0400 Subject: Use fee/priority estimates in wallet CreateTransaction The wallet now uses the mempool fee estimator with a new command-line option: -txconfirmtarget (default: 1) instead of using hard-coded fees or priorities. A new bitcoind that hasn't seen enough transactions to estimate will fall back to the old hard-coded minimum priority or transaction fee. -paytxfee option overrides -txconfirmtarget. Relaying and mining code isn't changed. For Qt, the coin control dialog now uses priority estimates to label transaction priority (instead of hard-coded constants); unspent outputs were consistently labeled with a much higher priority than is justified by the free transactions actually being accepted into blocks. I did not implement any GUI for setting -txconfirmtarget; I would suggest getting rid of the "Pay transaction fee" GUI and replace it with either "target number of confirmations" or maybe a "faster confirmation <--> lower fee" slider or select box. --- src/core.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/core.h') diff --git a/src/core.h b/src/core.h index 8606831575..d6e7ab870d 100644 --- a/src/core.h +++ b/src/core.h @@ -131,7 +131,8 @@ public: friend bool operator<(const CFeeRate& a, const CFeeRate& b) { return a.nSatoshisPerK < b.nSatoshisPerK; } friend bool operator>(const CFeeRate& a, const CFeeRate& b) { return a.nSatoshisPerK > b.nSatoshisPerK; } friend bool operator==(const CFeeRate& a, const CFeeRate& b) { return a.nSatoshisPerK == b.nSatoshisPerK; } - + friend bool operator<=(const CFeeRate& a, const CFeeRate& b) { return a.nSatoshisPerK <= b.nSatoshisPerK; } + friend bool operator>=(const CFeeRate& a, const CFeeRate& b) { return a.nSatoshisPerK >= b.nSatoshisPerK; } std::string ToString() const; IMPLEMENT_SERIALIZE( READWRITE(nSatoshisPerK); ) -- cgit v1.2.3
