The Lightning Network (Testnet)

README.md

Forked from vasturiano, with dataset and minor other changes.

The Lightning Network as seen from my node at 00:30 UTC on June 7 2018. This data is updated manually, not automatically.

Nodes are colored according to settings set by the node operators. Nodes are sized according to the total amount of BTC in channels they have open. Lines are channels between nodes. Nodes that fly off into the background don't have any channels my node knows about. Line colors are representative of the channel capacity, but is colored dynamically.

Click on a node to see its address info and capacity.
