Detailed output file contents

In order to get stable daily LN node statistics, we recommend to run the simulator for multiple times over several consecutive snapshots. Node statistics in each output file below are restricted to a single traffic simulator experiment!

lengths_distrib.csv

Distribution of payment path length for the sampled transactions. Due to the source routing nature of LN, we assumed that transactions are executed on the cheapest path between the sender and the recipient.

Column	Description
First	Payment path length
Second	Number of sampled transactions with given length

Note: the length is marked -1 if the payment failed (there was no available path for routing)

Note: the sum of transactions in the second column could be less then the predefined number of payments to simulate. The difference is the number of randomly sampled loop transactions with identical sender and recipient node.

router_incomes.csv

Contains statistics on nodes that forwarded payments in the simulation. We refer to these nodes as routers.

Column	Description
node	LN node public key
fee	routing income
num_trans	number of routed transactions

source_fees.csv

Contains statistics on payment initiator nodes (senders).

Column	Description
source	LN node that initiated the payment (sender node)
num_trans	the number of transactions initiated by this node in the simulation
mean_fee	the mean transaction cost per payment

opt_fees.csv

Contains several estimated statistics for router nodes with regard to base fee optimization.

Column	Description
node	LN node public key
total_income	routing income
total_traffic	number of routed transactions
failed_traffic_ratio	ratio of failed transactions out of total_traffic payments if node is removed from LN
opt_delta	estimated optimal increase in base fee
income_diff	estimated increase in daily routing income after applying optimal base fee increment
