delegated token

[moodysalem]

staker is low level and allows one-to-many staking

fungible staked token can be higher level but simpler--each address only delegates to a single address

[moodysalem]

this could also serve the purpose of measuring each users' share of the total staked tokens over time, or that could be separate

if in the same contract:

• other contracts can cheaply compute the percent of total staked tokens a user had over a period
• but they must take custody at the beginning and end of the period anyway, or...
• the contract should store a list of snapshots a la the staker

if we store a list of snapshots in this fungible staked token, then the share of total staked tokens over any period can be computed externally without taking custody of the staked token

[moodysalem]

actually think this still has to be separate. even if you know the seconds per total staked over a period, you don't know the balance of each user over some arbitrary period
