Bitcoin-SONs Sanity Checks

CLI checks to ensure the successful installation of Bitcoin-SON node.

After installing a Bitcoin SON node, you might want to run some basic tests to ensure everything is running smoothly with your Bitcoin node. Here are a few bitcoin-cli commands that you can run to check your node's functionality.

You can use these commands to get an overview of the Bitcoin network, how your node connects to the network, and your configured wallet and address settings.

1. bitcoin-cli help

List all commands, or get help for a specified command.

bitcoin-cli help "command"

# For example...
# bitcoin-cli help "getblockchaininfo"

The "command" in the above code block can be one of any bitcoin-cli commands listed in the reference doc. It's also optional and if left out will list all available commands. The help command is a good place to start to ensure the bitcoin-cli is actually available on your system.

2. getblockchaininfo

Returns an object containing various state info regarding blockchain processing.

bitcoin-cli getblockchaininfo

This command doesn't have any parameters. Running this command will list a lot of important information about the chain and your node. This is the command to use to see how much of the chain your node has validated and that you are connected to Bitcoin's mainnet. Here's what is returned in the call:
