This is *not* a hard limit but a threshold to minimize the outbound +traffic. When the limit is about to be reached, the uploaded data is cut by not +serving historic blocks (blocks older than one week). +Moreover, any SPV peer is disconnected when they request a filtered block. + +This option can be specified in MiB per day and is turned off by default +(`-maxuploadtarget=0`). +The recommended minimum is 144 * MAX_BLOCK_SIZE (currently 144MB) per day. + +A more detailed documentation about keeping traffic low can be found in +[/doc/reducetraffic.md](/doc/reducetraffic.md). + 0.12.0 Change log =================
