0.12 default mintxfee too low to slow confirm & how to speed up confirm ? #7634

Hi , I upgrade bitcoin core to 0.12 , but 0.12 default tx fee too low to slow confirm transaction (tx fee => 0.00002260 without set mintxfee [0.11.2 : paytxfee , 0.12 : mintxfee]) ... like this

http://block.oklink.com/btc/tx/9d59d22c9c2e1a703dfafd215bf1c0eb63bc583539bcc66b6003d43cebad40d8

and the transaction is too slow and reject from blockchain.org : [[ Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database. ]]

and I fixed mintxfee and downgrade to 0.11.2 , now okay for another transactions , but is possible fast to confirm the transaction like use miner software to assign the transaction or add more txfee ? ( ...... same blockchain BTCs all been sent ... )

I guess your problem is not the fee. Your transaction is trying to spend a unconfirmed input: https://blockexplorer.com/tx/9d59d22c9c2e1a703dfafd215bf1c0eb63bc583539bcc66b6003d43cebad40d8

Your input had a extrem low static fee: https://blockexplorer.com/tx/55ff007f89e0f1fc34a3e00664427c072afcdedff4f803ee39d1045eb1e4ed2e

That's why your 9d59d22c9c2e1a703dfafd215bf1c0eb63bc583539bcc66b6003d43cebad40d8 is not confirming.

Hi , I show you what the happen and I use bitcoin core 0.12 and please don't close this ticket

I send 200+ transaction where I receive 200 BTCs , 20+ in ver 0.12 , 180+ in ver 0.11.2

so it's not "Your transaction is trying to spend a unconfirmed input" or "Your input had a extrem low static fee" , I use default value of ver 0.12 , if default value too low , it's a bug

Sorry. Didn't meant to close. Re-opening.

@JokerCatz You can refer to the release notes on how to set transaction fees: https://github.com/bitcoin/bitcoin/blob/v0.12.0/doc/release-notes.md#wallet-transaction-fees . Please note that -paytxfee and -mintxfee are fee rates (BTC/kB) which do not take into account current network conditions.

Personally, I'd recommend using floating fees by setting -txconfirmtarget=25 or -txconfirmtarget=2 (based on your needs).

@MarcoFalke okay , I got it , many thanx , dev team :) , and my ver0.12 transactions all confirmed , I don't know who help me , many...many...many thanx :D

Closing now. Thanks for response.

transactions all confirmed

I think there is some benevolent miner crawling the web for reports of unconfirmed low-fee transactions to bump their priority locally and spread happiness. :)

(At least, having a txid showing up on GitHub or reddit is a good indicator that it is not spam)
