CLN plugin to control who can establish a channel to your node and what parameters they use.
Current path finding algorithms have limitations. If you want to be a performant routing node you should vet the nodes that open channels to you.
git clone https://github.com/SeverinAlexB/cln-channel-acceptor
cd cln-channel-acceptor
pip3 install -r requirements.txt
cd ~/.lightning/plugins # Create the plugin folder if it doesn't exist yet.
ln -s %PathToClonedGit%/channel_acceptor.py channel_acceptor.py
Restart your lightning node to start the plugin or reload the settings.
The acceptor can be configured with a configuration file .lightning/channel_acceptor.yaml
.
A sample configuration is given here:
general:
min_channel_size_sat: 100000 # Every channel opened needs to be at least 100,000sat
public_channels:
allow_tor_only_nodes: false # Do not allow tor-only nodes to open public channels.
min_channel_size_sat: 5000000 # Every public channel needs to be at least 5M sat.
private_channels:
allow_tor_only_nodes: true # Allow private channels from tor-only nodes.
Sections
general
Applies to private and public channels.public_channels
Applies to public channels only. Overrides the general settings.private_channels
Applies to private channels only. Overrides the general settings.
Settings
min_channel_size_sat
Default: -1. Minimal channel size in satoshi. -1 means the setting is not applied.allow_tor_only_nodes
Default: true. A tor-only node only has Tor addresses and no IP addresses announced. If false prevents tor-only nodes to establish a channel.strict_tor_only_node_check
Default: false. The acceptor looks up the node address in the graph. If the node can't be found and therefore the addresses can't be determined, it rejects the node.dev_mode
Default: false. In general section only. Rejects all incoming channels. Logs the result of the acceptor in to logs.
Change the parameters of the following command to mount the Lighting RPC file from a server to your local machine via ssh.
rm -rf $HOME/.lightning/lightning-rpc && ssh -nNT -L $HOME/.lightning/lightning-rpc:/home/bitcoin/.lightning/bitcoin/lightning-rpc your.server.com
