Hello, first of all I’m sorry to hear that you’ve lost coins, I hope it’s not permanently. What happened?
The phrase you quote (“Electronic transactions for all”) is not something that comes from a core decision. We, the people who were around and active on the forum at the time, had a lot of different ideas for what Grin’s vision and mission statement, should be. What we wanted Grin to aim to reach, at some point. We even took a vote about it, but in the end were not able to reach a conclusive decision when we tried to agree on a final mission statement. I did some digging in the old meeting notes just now and found this note that you might find interesting:
I think it’s accurate to say that we’d like Grin to be usable for everyone. I also think it’s accurate to say that we’re not there yet, we have a lot of work to do before we get there. That’s why we’re here.
