There's a difference between Rootstock and the likes of OMNI and XCP. Both OMNI and XCP have their own coins and independent goals separate from bitcoin. Rootstock is an extension of bitcoin. It will have the backing of the bitcoin community.
It's a white paper, vaporware. We always hear those arguments when a project gets started. I remember hearing about that for Ethereum and even Bitshares.
They plan a limited release of their testnet to partners by the end of April and to the public by September. It may not happen by those dates, but it's highly probable something will come out w/ the amount of money they got.
Rootstock itself will not match Bitshares' performance. It doesn't have to. It's going after a different market and has to be just good enough. All it has to do is prove that sidechains work. Once that happens, bitcoin's network effect will take over. It wants Ethereum to do well because it ports into Rootstock's smart contracts.
Once the sidechains flood-gates open, I see people looking at the top 2.0 projects to fork as a quick way to build bitcoin into a new evolved entity. Great performance will be absorbed.
Sidechains is a ceiling waiting to be broken.
If the white paper turns to be indeed doable and I mean doable within 1 year.... BTS cannot do much really.
Their side chain approach is really trustless! What is the best we (BTS) can offer?
"Sidechain done/depending on Highly trusted group of individuals. Trusted by who?...well trusted by us."
We would have to use the same federated peg as Rootstock. We could use the witnesses as a start.
I believe their federated group will consist of themselves, miners, VCs, banks, and respected bitcoin devs. Initially, Rootstock doesn't need to convince you, me, or any decentralized advocate to trust their network. They only need to convince the people the federated group interacts with. So Digital Currency Group only needs to convince its high net-worth clients to support it. Banks their customers. Miners their pool members. The majority of users they target (ie. the public) won't even care about decentralization.
As for bitshares, those who believe in DPOS should support our federated group of witnesses. The trust factor is the same. Otherwise, we've got some convincing to do. It would be nice if there were companies interested in bitshares to participate. As far as I can tell, there are none. Part of the problem?
We either win big or lose big. There is no middle ground.
