Did you just check out / clone a repository and forget --recursive / --recurse-submodules? Well, do this:

git submodule update --init --recursive --remote

"""Wireguard logging and monitoring tool.

Logs the following events along with the peer state in JSON format to stdout:
- Peer connected (= successfull handshake after period of no handshakes)
- Peer disconnected (= no handshake for longer than 5 minutes)
- Peer roamed (= source IP of the peer changed)

Additionally, the tool exposes a Prometheus-compatible monitoring endpoint
on port 9000 that exports the following metrics:

Your blockchain must have all of the following properties:

• It's a merkle tree, or a construct with equivalent properties.
• There is no single point of trust or authority; nodes are operated by different parties.
• Multiple 'forks' of the blockchain may exist - that is, nodes may disagree on what the full sequence of blocks looks like.
• In the case of such a fork, there must exist a deterministic consensus algorithm of some sort to decide what the "real" blockchain looks like (ie. which fork is "correct").
• The consensus algorithm must be executable with only the information contained in the blockchain (or its forks), and no external input (eg. no decisionmaking from a centralized 'trust node').

If your blockchain is missing any of the above properties, it is not a blockchain, it is just a ledger.
