- people will get extra keys if they’re worth more than they cost.
- with the puppeteer attack, illicit keys cost ~$20–$100 each.
- the more chances there are to use illicit keys, the more each key is worth
- we’re probably screwed unless we can make the cost of obtaining illicit keys scale up with adoption. also, we need to coordinate on not going over our shared security budget.
