Consider tokenomics of multichain, design a reward system

[DavidM-D]

Currently working on this.
Should the discussion/documentation of this live in the MPC repo @volovyks ?

@DavidM-D I think yes. Once it's finalized - we can mirror it in docs.

FYI I briefly discussed tokenomics with Michel (the WIP design with slashable pots) and he said there might be some we could do with forward-secure signatures to have better security invariants against past validators. Nothing specific yet, but he said he is going to explore this.

That'd be super helpful, although I have no idea how it'd be possible...

Here is a document written by Michel on forward security: https://docs.google.com/document/d/1a1ilRVGkDYoKn3WxAhTDUAy15XfbE9XWvr_zMJ_ai84/edit#heading=h.bqupaxg6kupz

Unfortunately, there is no clear way of enforcing this behavior since there is no way of distinguishing a server that behaves honestly from a server that updates their secret key material without deleting their old one. But this can potentially be useful for nodes that want to protect their own key which is a completely different problem.
