Also, it tells me its pruned. HDD used space ist just 20GB. It that something i should change? (Can i easily change it?)
Your node can still accept inbound peers even if your blockchain is pruned.
You don't have to if you don't want to sync again from start, your disk space is limited and you don't mind the limitations of a node in pruned mode.
ok, so i dont want to create a wallet, or load an old wallet. I just want to run a node for the sake of the network.
With a pruned blockchain, your node wont be able to serve historical blocks to new nodes that are in early IBD state (
take this in consideration of your decision)
But it still verifies and relay transactions as well as serving the recent 288 blocks regardless of the prune size you selected.
Hey, so im back and it worked. just now its fully synced.
-snip-
But i only got outbound connections.
This is the part where you need specific help from that Internet Service Provider or users who are using the same router and ISP.
If you want a workaround, try setting up "
Tor", that it should enable your node to accept inbound connections even if your ISP wont.
First, read the basics in this documentation:
github.com/bitcoin/bitcoin/blob/master/doc/tor.mdAnd or course, you need to install/setup Tor in your machine. (
preferably the service and not the browser bundle, setup differs per OS)
If you can't figure something out, post a new topic in
Bitcoin Technical Support board containing the details of what you done so far.
