Sidechains ... coming up next!! exciting times!
http://www.coindesk.com/blockstream-open-source-code-sidechains/Open source, "nothing up my sleeve", genuine article, don't settle for fake 'solutions' (xt) with hidden agendas.
We won't need tptb to continue the trainwreck from here, the SC buzz will send frappe.doc over the edge.
Looking forward to a 'Monero'-like ring signature sidechain and Lightning network sidechain as first working demonstrations for the force of the distributed sidechain solution of self-similar networks operating concomitantly at multiple scales transferring value effortlessly up and down the wealth cascade.
The two-way peg requires a soft-fork, and unless some significant rework of the idea has happened that I'm not aware of, the current prototypes perform the peg with federated servers.
It's entirely possible within the current development environment for any of a number of devs to prevent this from ever happening indefinitely.
Also, the only reason you would need a Lightning network sidechain is if the softfork opcode changes Lightning requires never make it into Core, which is the exact same political situation as getting a two-way peg in the first place.
