# BTCPRUNEBEFOREHEIGHT is chosen to be 504500, the date when lightning was starting to be used

|
# NBXPLORER_PRUNEKEEPONLY is aiming for 100 GB of storage
|
|
|
|
|
# Calculation input: 2 MB per Block (mbPerBlock), 1 Block every 10 Min (blockPerMin), Target size 100 GB (targetSizeGB)

|
|
# Formula:
|
|
|
|
|
# blocksPerDay = 24*60/blockPerMin = 144
|
|
|
|
|
# gbPerDay = blocksPerDay * mbPerBlock = 288
|
|
|
|
|
# daysToKeep = targetSizeGB / gbPerDay = 347.2
|
|
|
|
|
# blocksToKeep = daysToKeep * blocksPerDay = 50000
