Looking at Lisks website. Lisk dapps are not embedded in the blockchain like smart contracts. They need to be hosted by nodes on the network.
While it probably is good way to do it for many things, personally I think ETH is a better solution for Inchain.
Also Lisk havent reached the Lisk App SDK stabilisation milestone on their road map yet.
3. Lisk App SDK stabilisation
Stabilising our sidechains and making it possible for developers to start working on blockchain applications
So while it is possible to deploy dapps now, there will be major changes to the process later, making it too early to deploy large projects on Lisk imo.
Also Lisks latest hard fork was less than a month ago with 0.3.4
You're absolutely right. Eth is the best way for Inchain. And I'm also worried how can Lisk handle such a big project at this moment. Inchain has sitll 5 weeks to deliver it's tokens and Eth network should stabilize after this hard fork.
