Each veFXS will have 1 vote in governance proposals. Staking 1 FXS for the maximum time, 4 years, would generate 4 veFXS. This veFXS balance itself will slowly decay down to 1 veFXS after 4 years, at which time the user can redeem the veFXS back for FXS. In the meantime, the user can also increase their veFXS balance by locking up FXS, extending the lock end date, or both. It should be noted that veFXS is non-transferable and each account can only have a single lock duration meaning that a single address cannot lock certain FXS tokens for 2 years then another set of FXS tokens for 3 years etc. All FXS per account must have a uniform lock time.
