Blockstream has over $60mil in funding to develop side chains. With Confidential Transactions coming to Bitcoin, do you think privacy-centered altcoins like XMR will suffer a decline in demand against new side chains?
Don't worry, Blockstream is incompetent.
Another cluster-fuck of overconfidance as is Ethereum.
Side-chains can't ever work, unless they are merge-mined on the chain they side-channel.
Blockstream is basically proposing Segregated Witness which is reall a Trojan horse to take control over Bitcoin forks by introducing versioning (which will make it easier for them to soft-fork Bitcoin at-will).
Bitcoin is in a cluster-fuck already with China's mining cartel controlling 65% of the hashrate.
