# Sputnik Staking

This is staking contract for Sputnik DAO.

The default version just allows to stake the tokens by users and convert them into "weight" in the Sputnik itself.
Further modifications can be done to allow to leverage the staked token for other functions (providing liquidity for example).


### Token voting

> DAO votes to select some token to become voting token (only can be done once, can't change later).

User flow to vote with selected token:

- Users deposit the desired amount of the token to the separate staking contract defined by the DAO.
- They can then choose who to delegate these tokens. It can be to themselves or to other users to increase their vote weight.
- When users vote for proposals, their vote is weighted by all the delegations to them.
- Undelegating will block delegating / withdrawing until one voting period passes.
- Undelegated tokens can be withdrawn by the user.



## Scripted Flow

NOTE: This is not 100% working, help finalize :)
