I set settxfee=0.0001,but it seems to be calculated with /KB.Can I send a fixed transaction fee?Like I set fee is 0.0001,the transaction fee is 0.0001 also.

According to NIST and ECRYPT II, the cryptographic algorithms used in
Bitcoin are expected to be strong until at least 2030. (After that, it
will not be too difficult to transition to different algorithms.)

I wouldn't recommend it. You could send a huge transaction with that tiny fee and get your funds frozen in the mempool. Or you could even overpay. 0.0001 is pretty low nowadays.

At least, i have coin controll enabled, and when i create a transaction ("send"-tab), i see a buttom "choose" net to the current transaction fee. When i click said button, i can chose whatever fee i'd like. If you use bitcoin-cli you can also chose your own fee by creating a transaction manually: create a raw transaction picking your inputs and outputs, and the difference between in and out is the fee. Sign this raw transaction, broadcast it with the fee of your liking... A bit harder, but still doable. But like been said before: it's not a good idear to use a (low) standard fee, sometimes you'll grossly overpay, most of the time your transaction will take a long time to confirm (depending on the size current mempool, fees of unconfirmed transactions, transaction size and luck)!!!

--snip-- Will lower fee delay the transaction? can fee be set to zero or is there a minimum value? if there is a minimum value than how is it different from existing wallets?
Depends on a lot of factors... If your transaction is a high priority transaction***, you can try not to add any fees... Altough most miners will not add your tx to a block without it having a fee, there are still some good samaritans that add zero-fee high priority transactions to their blocks. For everyone else, there are sites like this one: https://bitcoinfees.21.co/1) estimate your transaction size (in bytes, NOT in satoshi's)** 2) multiply by the number found on https://bitcoinfees.21.co/ , it's your own pick if you want the transaction to have a high probability of being added to the next block, or if you're willing to wait a bit longer. Long story short: it depends on the size (in BTC) and age (in confirmations) of your inputs to determine the priority. If it's high enough, you can try a zero-fee tx, but it can take a long time to confirm. If you can't create a high priority transaction, you should add a fee, how much depends mostly on the number of inputs and outputs of your transaction. Adding to much won't help you a single bit, adding to little might slow down the first confirmation, adding exactly enough would be ideal BTW: i don't quite get the last part of your question: "how is it different from existing wallets?". I'm saying the OP can run bitcoind and use a json-rpc connection to create a transaction. Bitcoind is the "original". It's usually installed together with bitcoin-qt and was the first wallet. bitcoind is also the daemon that is ran by the nodes everybody relies on ** size can be estimated by: [number of inputs]*180 + [number of outputs]*34 + 10 *** priority = sum(input_value_in_base_units * input_age)/size_in_bytes high priority = a priority above 57,600,000 source: https://en.bitcoin.it/wiki/Transaction_fees
