Im not logged right now into my node computer but I think on the bins folder there was a bitcoin-test or something like that executable which I assume launches Knots in testnet mode. My question is, does it use testnet3 or testnet4 by default?
For clarification, that "
test_bitcoin" executable in bin/daemon directory isn't for launching the node in testnet3 nor testnet4.
That's for unit test purposes.
You must run bitcoind or bitcoin-qt with
--testnet (
testnet3) or
--testnet4 arg to launch it in testnet.
If you're also talking about the shortcut in Windows when you used the installer (
set-up) version,
It's in testnet3 since the shortcut has
--testnet arg when you check its parameters.
