Hey 👋!
Welcome to this really simple project for making handshakes to p2p nodes. Currently, supporting the Bitcoin P2P protocol.
If you are interested in how this project was designed and further explanations, please look at the NOTES page. And, if you want to better understand what this intent to resolve, please see the instructions page.
Example output:
› NODE_ADDRESSES="195.123.221.104:8333 89.177.13.137:8333 54.144.114.87:8333" USER_AGENT="/Satoshi:25.0.0/" cargo run
Connected to Bitcoin node at "54.144.114.87:8333"
Connected to Bitcoin node at "195.123.221.104:8333"
Connected to Bitcoin node at "89.177.13.137:8333"
✅ 195.123.221.104:8333: Bitcoin handshake successful!
❌ 89.177.13.137:8333: P2P Error: deadline has elapsed
✅ 54.144.114.87:8333: Bitcoin handshake successful!A rust installation is needed.
As an example, you can download the Bitcoin core node and run it on your machine. It's worth noting that you can change the running port of this particular node if that's clearer (update the bitcoin.conf with port=YOUR_CUSTOM_PORT).
cargo runYou can also change the adress(es) and user agent via the env vars NODE_ADDRESSES and USER_AGENT. Same as explained below.
Other option, is to pick a node from the list of available nodes, and run:
NODE_ADDRESSES="<ip_address:port> <ip_address:port>" USER_AGENT=<user_agent> cargo testUnlicensed. See LICENSE.
