at #188379!!! 90k more blocks to go. Slowed down quite a bit. I’m wondering why its getting longer to mine a block.
Not sure either tbh, maybe the difficulty increased? 
Never did that many blocks on regtest 
My computer reached 209200 blocks, so i’m almost there!!! I have a problem though, i can’t list my wallets.
Are these blocks on the mainnet, how do you generate these blocks?
These are blocks on regtest.
Hi Alko89
I’ve tried to add a fallback fee in bitcoind, however, I’m getting an error message as it doesn’t seem to like the decimal point.
Please see attached screenshot.
Have you tried using quotations for the number? -fallbackfee='0.00001'

This worked. Thank you 
I’m trying to get help creating a wallet in bitcoin-cli
Hello and happy new year to everyone!
Not sure if it matters at all, but I noticed that when executing mainnet, testnet or regtest, it is not necessary to also type “-printtoconsole”… someone can maybe chime in and tell me if they find it necessary? I seem to be able to do it either way 
just thought I’d share
Happy new year to you to @kyliemerk!
Its not necessary no, but its much better for debugging and seeing what is happening with the daemon when you’re learning.
Anyone new to the course, is probably using a much more updated version of bitcoin core so many of these command lines Ivan uses do not work anymore here are some updates to make this all work
First pic:
bitcoin-cli -regtest createwallet “testwallet”
-seemed that I needed to do this first before anything would work even though it gives you that warning it still works
Second pic I generated a new address and then mined 101 new blocks

Very useful, they should update it. It would be a lot easier for us !
Hello everyone! I am receiving this kind of message:
error code: -18
error message:
No wallet is loaded. Load a wallet using loadwallet or create a new one with createwallet. (Note: A default wallet is no longer automatically created)
PS C:\Program Files\Bitcoin\daemon>
Anyone could help me how to load wallet? Thank you in advance
Did you create a new wallet with bitcoin-cli -regtest createwallet "<WALLETNAME>"?
Thank you for reply. It sounds maybe a bit more simple, but if I try to create wallet, it gives me that database already exists…
error code: -4
error message:
Wallet file verification failed. Failed to create database path ‘C:\Users\Martina\AppData\Roaming\Bitcoin\regtest\wallets\wallet_name’. Database already exists.
I don’t know what to do…
Thank you so much! Very helpful!
thank you, very helpful!
Looks like you already created a wallet. You can load it with bitcoin-cli -regtest loadwallet wallet_name, or create a new one with a different name.
