Hey guys,
When I enter the ./bitcoind -printtoconsole command in PowerShell, I get a return :
āPlease restart with -reindex or -reindexchainstate to recover. You need to rebuild the database using -reindex to go back to unpruned mode. This will redownload the entire blockchain.ā
Then it proceeds to shut down and exit.
I do not have the disk space to host the whole blockchain at the moment. Is that gonna be an issue for this course?
You have to run the node in regtest mode so it wonāt take much space at all.

bitcoind
[/quote] w
i checked itā¦ but its not thereā¦ although i have wallet workingā¦ let me attach screenshot of content folderā¦ 
Below text is copied form the bitcoin.org ā¦
The Bitcoin Core daemon (bitcoind) is not included in the .dmg file you may have downloaded to install Bitcoin-QT. Bitcoind, along with its support binaries, is instead included in the OS X .tar.gz file listed on the official Bitcoin Core download page. To download this file using Terminal, execute the following command:
curl -O https://bitcoin.org/bin/bitcoin-core-0.21.1/bitcoin-0.21.1-osx64.tar.gz
i did install this package and now i have the fileā¦and its working. thanks

Hello! When I ran it on powershell, it said āshut down doneā and ended even without me pressing control C, i started it up and it said a bunch of text and then shut down. I did not have both clients open, although i never fully synced the first client as it said 9 hours left so i closed it down to continue on the lesson, i am unsure if i needed that to be fully synced first despite it being a seperate application.
Please help!

This is my error, I ended up waiting for bitcoin core to be fully synced and this still just happened when i closed out of bitcoin core fully and then tried running bitcoind. Let me know if I need to share above what happened or not, i can blur out my personal details.
I am using ./bitcoind -printtoconsole on powershell
Youāre just using reindex without any command. You probable meant bitcoind -reindex

Thank you! that worked and then i ran it normally and it kept showing a bunch of crazy stuff as shown in the ivan video, i was able to use ctrl + c to shut it down Thanks for the help!
Hi everyone,
I am looking for an advise on the following:
- Do I need a dedicated machine to run Bitcoin Core (full node)?
- What are the hardware requirements to run Bitcoin Core?
- It is faster to run Bitcoin Core on Linux vs WIN10 or macOS if on mainnet?
- What are the best practices to run and maintain Bitcoin Core on mainnet?
Many thanks
Not really, but I would recommend it if you intend to run it on mainnet.
Not sure, pretty low. It can run on basically any hw with enough storage.
Linux without a UI will definitely give you the least overhead.
Just having it online as much as possible for the node to keep syncing.

Thank you, i had the same problemā¦ It works now!
Hi guys Iām using a Mac and when I download Bitcoin Core there is no Daemon file with the other programs (only the .Qt file). What am I doing wrong?
You have to download the tar.gz file for Mac os, not the dmg.
