Each Token Grant will vest monthly at a maximum 12 month vesting schedule or until the total tokens are distributed, with a minimum 100 tokens per month.
For example, if a 1,000 Token Grant was earned, then it would vest monthly at 100/month for 10 months. If a 1,500 Token Grant was earned, then it would vest at 125/month for 12 months.
The first distribution will occur in the month following the completion of the work.
The 12 month vesting period helps ensure tokens (and thereby ownership + control of the network) are distributed evenly over time. Vesting tokens over 12 months is very standard practice, particularly once the token is liquid. This helps to ensure the network remains fully decentralized and balanced.
