How to check NODE type in Bitcoin?

Question

There is a Bitcoin node in my Lab, how can I check it is a Full node or not? there is any command to check node type?

Answer 1

I assume you mean to ask whether the node has the complete blockchain or is pruning.

Connect to the node and call bitcoin-cli getnetworkinfo, it tells you the version, and the “localservicenames”. If your node offers NETWORK and NETWORK_LIMITED it has the full blockchain. If it only offers NETWORK_LIMITED, but not NETWORK it is a pruning node.

If it is a very old version, you may need to use a different command, you can find documentation of the RPC commands here: https://bitcoincore.org/en/doc/
