What do you mean by world's first blockchain ecosystem for building and deploying Dapps? Weren't Dapps being built much before Arcblock? And then I have a confusion. You claim to have your own optimized blockchain, but you will be transferring tokens to the ERC-20 compatible ETH wallet! Will you be converting these tokens to your coins at a later stage (like EOS) or these ERC-20 tokens will be the standard currency on your platform? Lastly, I would wish to see links embedded in your media section. There are just images, not clickable links for further research.
From what I understand the "ecosystem" they are trying to build is cross-chain, meaning that devs don't need to choose which blockchain they want their DAPPs to run on. DAPPs that are on ArcBlock can also be accessed through different chains such as ethereum, bitcoin core. Also, they want to build something that integrates front-end, back-end, cloud computing...etc. It's actually pretty similar to EOS, lol.
Hope this helps.
