Thanks for raising this issue, you're right! There's no mechanism for making concurrent work impossible. We haven't had this problem of concurrent issues being worked on from start to finish in the past, maybe that will change with the bounty program? We haven't seen adversarial behavior yet but if it starts to be a problem we can address it, I agree that the language of "opening a PR" isn't super great. Maybe that section needs to be more general i.e. "we'll assign you the issue once you've made substantial progress towards the tasks" leaving that to be defined by maintainers. The possibility of "staking" money by the contributor is a non-starter. We aren't in the business of taking money from people who have good intentions and operationally I don't see a way forward there. This whole program is an experiment so we're open to being wrong about things at first. We'll be iterating based on feedback and providing a retrospective in a future newsletter.
