Introduce token voting and lock period before FRAME

[Asamartino]

Based on a discussion in the instructor channel, the Econ & Game theory in Blockchain, should include:

• token voting
• lock period based on conviction

IMO This is in the idea phase.

I think a game of governance in the classroom can "explain by example" how everything works in the gov scope. It could be an activity of 1 hour with random referenda

Another good place to explore this could be in the contracts module. Students could implement this as a solidity or ink! or other smart contract.
