Or a bot
No, definitely not a bot. Bots are centralized and require trust; Pocket isn't (at least not necessarily) and doesn't. That'll have to be the subject of today's blog post, to clear up that misconception. Pocket is definitely a token sub/sidechain.
I feel that it is somehow similar to ERC20 tokens.
That's the idea.
By the way - when I first saw the title of your announcements I thought about this Pocket. Are you familiar with it?
I hadn't heard of it. Maybe the Pocket I created will get big enough one day to worry about there being other Pockets out there. :)
