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.
