Upgrade from honest majority to rational majority

[dr-orlovsky]

In order to prevent honest majority from uniting against minority in stealing their funds it is suggested to align economic interests of sidechain validators with the security and adoption of the sidechain itself. For this reason every validator additionally to the stack lock on the maon chaon must provide proof of burn output in the same transaction, which will be used by sidechain consensus to produce sodechain bitcoins locked in sidechain for n>>2 epochs.

By doing so we can move from the honest majority assumption to rational majority assumption increasing sidechain safety
