Bootstrap Me

Overview

A simple little tool to help you launch a node on any Cosmos chain a bit easier and faster than it would've been. This is not intended to be a Terraform-based "node launcher", but rather a tool to give you better visibility of a chain while launching a node. Lots of interesting ideas to build out. Stay tuned anon.

Features

• Grab chain.json for any chain on the Cosmos Chain Registry
• Fetch the persistent peers and seeds listed and check if they are still reachable
• (Optional) Perform a port scanning on the reachable hosts. If a host has ports open that shouldn't be exposed, you can then decide whether to take it out from the final list
• (Optional) Fetch geo data for the reachable hosts
• Remove unreachable hosts and generate a final, concatenated list of reachable persistent peer/seeds

Sample

$ go run main.go --chain <chain> --scan true > log
$ go run main.go --help # see all supported chains
