I’ve been thinking about this a lot recently, and it raised another question along the same lines. What’s the use case for any of the privacy coins if bitcoin adds features that allow bitcoin users to easily maintain their privacy?
So, I don’t really know much about the technical side of grin (I’m a slow learner, I’m getting there), but my gut (with the help of the comments here) tells me that the use cases have something to do with grin’s lightweight chain, and something having to do with how transactions are a bit different on grin. That little difference I noticed was drawn to my attention when I went to withdraw some grin from tradeogre, and instead of sending to an address to witdraw, I just downloaded a file which I’m supposed to then use the grin wallet to finalize. Like I said, I’m still learning, but it seems like there’s some fundamental difference in the way grin handles data and transactions that will suppliment bitcoin in some way. I think I’m on the right track, we’ll see.
That being said, it seems like grin’s use case is to be THE e-cash of the world. Thinking sort of abstractly I think of grin as an extension to bitcoin, something that allows for private transactions, no matter the cost of a satoshi. I think if we assume a fully bitcoinized world, then the grin project means devs today, taking a moral responsibilty to ensure future generations have the ability to transact without the need for middlemen or government arbitration.
It is easier for entities like governments to maintain control of their bitcoin savings throughout generations, because governments live longer than people. The odds of an accident happening to me, and me not being able to pass on my coins to my children are way too high, so those coins would be lost. So it seems like bitcoin will just get more and more scarce over time. I think this means that governments could slowly accumulate so much bitcoin, that there’s just not enough to go around anymore. Grin prevents that by adding a constant velocity of money. To me, that means the foresight of the grin developers is just incredible, and they’re making something great, it’s just a beautiful thing to me, so thank you for that. It’s very thoughtful of you to consider people 100 years from now, 1000 years from now. Y’all could have easily added some shady block reward funding shit in there, or giant block reward incentives for the first few months, or some premine, and made a killing, but you didn’t…that’s like, satoshi level morals. I want to buy you all gift baskets with mini-muffins chocolate and flowers. Anyway, I digress.
So now that that stream of consciousness is done, to paraphrase, if someone ask me what grin’s use case is, is like asking me what money’s use case is. Grin is just proper, bullshitless, e-cash.
