If one would like to position their relay on the hashring at a specific spot, you can bruteforce the key generation to match the first bytes of the fingerprint. Usually 4 or 5 bytes are enough and it doesn't take that long to compute. And because the position on the hashring is predictable over time for hidden service *version 2*, then anyone can setup relays that in 5 days will be at the right position. Thus the importance to catch these relays before they get the HSDir flag that is 96 hours of uptime. Cheers! David -- WzhUyhDvWQI2JZglnMWl4fhIHYln5DpMG50IrXaHPLU=
