Voting Escrow Snapshots: Historical snapshots of previous voting escrow balances.
Motivation
There are several instances in which one may want to use an instantaneous snapshot of all vote escrow balances, for example:
- Fee distribution. One may want to send protocol revenue to veToken holders.
- Airdrops. One may want to send tokens to holders of a veToken.
Mechanism
veToken balances are recorded for every period. A period is recorded for every 3 days.
There are two accounts that are used to compute historical balances:
- [LockerHistory], which stores the total number of veTokens for each period, and
- [EscrowHistory], which stores the veTokens in each Escrow per period.
Any time someone refreshes and/or modifies their vote escrow, they should refresh their [EscrowHistory] accounts.
