Hey, Sorin!

Sorry for a delayed reply.

Here is how things stand on our side...

Our choice to go with a fork of VeChain instead of Steem is largely due to the inbuilt IoT capabilities. IoT was the biggest factor as ours is an IoT heavy solution.

Regarding the "ethereum ecosystem compatibility," we will be deploying different smart contracts that will facilitate various functions of the network. Until we've established a PlayMaker smart contract framework the Ethereum compatibility will be a great compliment.

VeChain has launched several dApps the most common being the OceanX Decentralized Exchange. You'd have to do more research on that if its something you'd like to know more. We've also found the VeChain as helpful, I agree it would have been a challenge if they weren't.

Thanks for the Steem suggestion - perhaps we'll look into it to find solutions we could incorporate into PlayMaker.

In the meantime, since you have given us good feedback regarding what we should explain more thoroughly, we have composed an article about why we have chosen VeChain. You can read it here: https://steemit.com/blockchain/@playmakerchain/why-is-playmaker-building-on-vechain-architecture

Cheers! ;-)
