p2px

p2p-exposed

This is a simple web service for checking what blockchain ports are exposed to the internet. It is useful for two reasons, not having P2P ports open can make peering more difficult, and accidently exposing RPC ports can create security risks.

Supported chains

How does it work?

From the host that will to be scanned, simply send an HTTP request to the service and it will print out the results. The scan uses a pre-defined list of ports and usually finishes in only a couple of seconds. There is a publicly available endpoint running at https://p2p.exposed

Contributions Welcome!

Currently this only supports 3 chains, but it is easy to add more. If you want to contribute, please submit a PR with the ports and a description and I'll add the necessary code. See sigs/cosmos-ports.yml for an example.

Example:

$ curl p2p.exposed/cosmos
