I think it's one of the first projects that will be integrated with ARK. It is however, if I am not mistaking, a totally independent project with ARK partnership. And part of ARK's community is also working or just actively support Persona project.

This is a good example of interoperability, you don't even need a VM for smart contracts (even if Ark it will) if you can bridge another chain for deploy them!

The question is where the working product? If no working product how they know if even it work?

Trade ARK on Bittrex or Binance.
Where is the problem?

Agreed with you that is ongoing process the team is working truly amazing to improve the quality of this network and bring user friendly features. ARK is undervalued project even in recent dump phase it showing very impressive performance. I believe future will be more brighter than ever.

All this correction is convincing me more and more that whenever next bull start behind that serious investors will be standing on. We will see ranks of markets based on their techs and use cases and Ark should be among top markets. All this recently completed will pay as huge success once we are out of this temporary state of uncertainty.

Hey Ark people! I think what Ark really need is in wallet exchange where any ICO, Ark fork or Smartbridge chain would creating their own exchange market with Ark, Bitcoin or others Ark forks. Something like Aces with extending to the in wallet. This way they don't need a centralized exchange, which is very hard to get list right now. This also would encourage more projects to look into Ark.
It sound like Ark creating lot of useless shits, the reason it's not pumping.
Still, I lose a lot of money in this crap.

Wallet version 2.0 is Perfect with nice design.

You're suggesting something like Waves' DEX ? I think it's a good idea, tools to make the whole decentralized are there, I don't know if 8 sec blocktime is enough though
