From the stream summary:
"Bounty Hunting
How are bounties obtained? - Bounties will be able to received from an NPC. This will pull from a random pool of player murderers. Only the single bounty hunter will be able to obtain the reward for the completed bounty. Once the head is delivered to the bounty hunter NPC, you will receive the reward. Players will be able to add rewards to the random bounty system if they have a head they want collected, but there will be no integrated system for player made bounties. That will have to be done between players.
Will Bounty Hunters have Ranks? - Yes, completed bounties will contribute to your rank for leaderboard placement. Ranks will also give you access to other Bounty Hunter tools and can be expanded on at a future date. This also includes titles.
What should I know if I am a murderer? - If you have a over 5 Murder Counts, you are considered a murderer and will be placed inside the random Bounty Hunter pool. If you are hunted, there will be a grace period where you cannot be hunted again. There is a plan to add a "Most Wanted" list for the public to know who is avoiding or winning against bounty hunters attacks.
Tracking - We are still finalizing some lore relating naming however there will be a tracking tool. This tool will only work per bounty. It will ping you a generalized location of your bounty hunter target. It will have a timer when it can be used again, this making sure you still have to track the target. If the tool becomes a bird in finalization, you will not need specific lore to use the tool/animal."
