Blockchain 2.0 is based upon an economic fallacy of a 'scarcity race', the security fallacy of hash power, and has a giant security hole that would compromise entire side chains. It has embraced a concept of centralization in a one-world currency, one block chain, etc. It has embraced barriers to entry by not enabling support for cross-chain-trading.
Based on this description it works just like a system I designed last fall in my effort to create parallel chains with shared supply. The problem is that when using pow the side chain funds can be completely robbed because the main chain cannot validate anything but the existence of the trx on the side chain. So to do this the btc miners still have to do full validation on all side chains.
This major security risk has not been mitigated.
In other words 51% attack on side chain allows attacker to steal full balance of side chain by transferring 100 % of it back to btc chain under their control. Btc miners would see the transaction exists on the side chain but have no way of knowing it was invalid because they blindly trust the hash power.
This makes new side chains very vulnerable unless all btc miners merge mine it.
If you eliminate the contrived idea of a scarcity race and the false security of hash power there is nothing to this Blockchain 2.0.
Integrating a technology like BTS X into a side chain would require significant R&D... the ideas behind BTS X are easy, implementing them is much harder. Assuming BitBTC works then we have achieved a peg with BTC already without needing their system. Cross-chain-trading is all that Bitcoin needs to support, could be implemented today without any modifications. You do not see Bitcoin developers / mining pool operators working to enable this support which would literally be a few lines of code to add it to the standard transaction type.
The bitcoin elite (pool operators and miners) *own* the sha256 space and thus want to expand their monopoly. Bitcoin has a network effect, but with cross-chain-trading that network effect can quickly and easily benefit all alt-chains... but their behavior demonstrates that they have been corrupted by the ring of power. Like the elite before them they are inventing economic concepts (scarcity race) just like the fed invents terms (QE, disinflation, paradox of thrift, etc) to justify their moves. They are working with regulators already which means they will likely support moves to freeze accounts so that they can continue the gravy train.
These factors demonstrate to me that regardless of how large the BTC network effect is, they will not be able to out compete everyone because there will always be a market for a more decentralized system than bitcoin offers.
