I've been following the perpetual DEX track for a while. Recently, a leading project launched an order placement mining mechanism specifically to subsidize liquidity providers, and the model is quite interesting.

How are points calculated? It mainly comes down to three aspects: First, order size is the main factor. The larger the orders you place, the higher the base points you earn, which is the biggest influencing factor. Second is the time dimension - the system accumulates your order placement duration by the minute. In other words, the longer your orders stay on the books, the more points accumulate - users with strong stability can earn more rewards. The third aspect involves the relationship between the order placement price and the current BTC price, which directly affects the real liquidity value of the order.

Overall, this mechanism is quite friendly to market makers, encouraging them to provide deep liquidity on a long-term basis.
