Talk about my understanding of POS, maybe there will be errors in understanding.
POS is a proof of equity. Just as we have idle funds and deposit the relevant funds in the bank, the bank will allocate interest according to the amount of funds within a certain period of time. We store the coins in the wallet and store them as if they were deposited in the bank. For a certain period of time, the coins deposited in the wallet will produce a certain number of coins. These newly generated coins are the interest generated by the coins deposited in the wallet.
In order to generate interest more equitably, when designing the POS mechanism, not only the weight of the network, but also the maximum stack time. When the maximum stack time is reached, regardless of the number of coins in the wallet, the interest is distributed once, and then the weight is cleared and recounted. This protects many customers who have a small number of coins and has no influence on the number of customers. If there is a maximum stack time setting, even if there is one coin in the wallet, you can get a POS reward.
