Thanks for your questions!<br>

<br>
We have not considered use by bounty hunters, however we have considered different task services, and that proposed in our paper is distinguished from those we are aware of in a number of ways. The primary being that every related idea we know of is essentially purpose built to facilitate crime or assassination marketplaces, and offer few "built-in" restrictions on the actual tasks posted (as in quality or ethics). In our view, this not only precludes such marketplaces from hosting other "good" tasks, but also prevents their wide-use and potential due to their inherent criminal foundation. For example we cite a paper by Juels, Kosba, and Shi that outlines one such marketplace, but all the applications the authors mention (or that we can think of for their marketplace) are criminal.<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">So a little while ago, I got rather interested in the commercial possibilities of making ice cream using liquid nitrogen.
