But Essentia and Bluzelle doing same thing. So what different here? And Imnot sure about Bluzelle, but Essentia will have own blockchain soon (by roadmap in Q4 this year). So what advantages have Cardstack if they evem will dont have own blcokchain? Who need ERC tokens now? People dissappointed in ERC tokens and only own blcokchain have real value.
You might want to refer to Cardstack's
Whitepaper for project specifics, you should then be able to compare Cardstack with other projects and see exactly what Cardstack is all about and how it is different. In what concerns ERC20 tokens, they'll most certainly be useful now and in the future.
Mate, from what I understnd this 3 projects are similar. And if they have competitors they must have a comparison with other similar projects (at last this making all good projects).
How tokens can be usefull right now if they still not used? May be they will be usefull, but only when product will be ready and tokens will be used. But in anyway native coins with own blockchain have much more value.
