Why @PlasmaFDN consensus design actually scales
scaling blockchains isn't just about tps, it is about coordination getting validators to agree FAST & SECURELY
but consensus at scale it is really hard 
here is how Plasma makes it work=

why is consensus hard at scale
more validators = more messages = exponential complexity
in worst cases, it can degrade to quadratic communication
that is a bottleneck for performance & reliability.

instead of everyone validating every block plasma picks a small set of validators each round
it is faster lighter and avoids message overload.

how does plasma pick the committee
via a cryptographically secure random process...
weighted by proof of stake
more stake = more chance of being chosen.

slashing= keeping validators honest
stake slashing = you misbehave you lose funds

reward slashing = misbehave slightly lose your rewards.
