LnRouter gives insights into various node metrics to choose the right nodes to connect to. To achieve this, LnRouter continuously measures nodes that pass the test criteria.

Test Criteria

Node

A node needs at least 15 channels of 2,500,000 satoshi capacity. Multiple channels to the same peer are counted as one. Additionally, 6 of these channels need at least 500,000 satoshi inbound capacity.

Channel

  • The channel has at least 2,500,000 satoshi capacity. The capacity of multiple channels to the same peer are added up.
  • Channel source and target nodes need to pass the node test criteria.
Only a subset of a node's channels are tested. The goal is not to test every channel possible but to test a subset to interfere the big picture. The channel selection is biased towards bigger channels.

How Is A Test Performed?

Lookups sends one 500,000 satoshi test payment in both directions of a channel. If a payment succeeds we know that this direction is able to route sats.

Scan Interval

LnRouter measures every node in a 4 week interval.
