I worked in crypto space for about 2 years ; and even tough we had great use of the crypto-system for our community ; it ended up being a large cost that we could have yielded better with something else - and it was not because specifically "crypto" - but because ultimately the engineering costs of a generic purpose chain are replicated to all child-chains. So you end up with drastic cost for something that would have seemed pretty simple to resolve. Not only that - the hole thing stinks with a lack of engineering methodology - there are so many ways to build a decentralized system and many of these are shadowed by the constraints and what-not blockchain overhead is adding. I'm not saying is *bad for everything* - i'm saying it's difficult to use properly ; and using a "chain as a service" ultimately provokes a lot of cost. For the one that stripe is providing ; I suspect it's a POA with standard implementation which is specifically tailored for building coins - and this is another subject which is very grey as indeed this provides a way to incentivize, construct "exchange contracts" for certain actions etc... - this is an interesting space - but as others are saying it's also very unregulated.

I'm cautious about these
