Configure Bitcoin Node
Think of your bitcoin node as a fake bitcoin detector, it will confirm that bitcoin’s consensus rules are being followed so that when you receive a payment you can validate that you are getting real bitcoins. It will also help with fee estimation, coin selection, and generating transactions.
Keep in mind that while a malicious full node can try to deceive you, it does not have access to your private keys.
You can install Specter-Desktop on your home computer alongside Bitcoin Core. Alternatively, you can use a product to setup your Bitcoin Core Node, such as RaspiBlitz, Nodl, and MyNode (Premium edition). They all come with Specter-Desktop packaged, but only RaspiBlitz is free (Nodl and myNode Premium are paid products).
In order for Specter-Desktop to connect to this full node, you’ll need to configure some settings in your
You can do this by going to the directory where Bitcoin is installed, and opening the bitcoin.conf file in a text editor (e.g. Notepad).
Insert the following 3 lines:
disablewallet=0 (you don’t need private keys in Bitcoin Core, but you need wallets to be enabled)
Then save, close, and reopen Bitcoin Core for the changes to apply.
You’ll also need a way to authenticate a connection to your node.
If this node is run on a different computer (a “remote” machine), you’ll need to know the
rpcpassword that your bitcoin core node is using.
We recommend setting
specter (if you can) for simplicity.
Note that for physically connecting hardware wallets using your laptop/desktop with Specter packaged on another device e.g. myNode, RaspiBlitz or Nodl, you may need to set up HWI Bridge.
If you can tweak your settings, we recommend the following (optional):
- Do not run your node in pruning mode as this disables
rescanfunctionality. In some edge cases you may need to rescan your node, and a pruned node will instead have to (automatically)
reindexthe whole blockchain (can take many hours to many days).
- If you have set
blockfilterindex=1, as suggested above, it takes just a few GB of storage and helps speedup blockchain
