1.5 Liquidity Mining (Mining Phase 2)

Users who have staked both Shard and LP Tokens can access liquidity mining in the Pools. The mining reward will be in SHD.

During this period, users can make SHD profit on ShardingDAO platform, following the rules of liquidity mining with "SHD-ETH" and "SHD-BNB" Tokens.Among them, the SHD rewards of the “SHD-ETH” and “SHD-BNB” mining pools accounted for 90%; the SHD rewards of the top 3 mining pools in the “Shard-Subscription Tokens” locked up volume accounted for 10%, Users who participate in pool mining will divide rewards equally.

Rewards Rules: Only the top 3 mining pools will share the mining rewards divided evenly. If there are less than 3 mining pools, all current mining pools will share the mining rewards equally.

Ranking Determinants: The protocol determines the ranks of pools solely on 'TVL', aka Total Value Locked, and it is priced in USD. The Protocol calculates a pool's TVL as the Total Staked of all users in the pool, including all the Tokens that have not been redeemed.

Ranking Updates: A user can request ranking updates. Choose a pool that is not in the top 3 and request to compare it to a pool in the top 3. If the top 3 pool has a TVL smaller than the other pool, the protocol will remove it from the top 3 list, even if there are other pools in the top 3 whose TVL is smaller than that of the pool being removed.

Staking rules

• Users who have staked LP Token cannot withdraw LP Tokens within the specified staking period. Users who redeem LP Tokens will no longer receive mining rewards. After the staking period expires, the user needs to redeem the staked Tokens manually. If there is no redemption after the expiration, the weight will continue to be calculated.

• Formula for calculating staking weight:

• Ratio of user rewards:

• Staking period: A user can stake for 1 month at least and 36 months at most.

Rules for calculating weights of multiple lock-ups:

In the case that the user locks the position multiple times, the user's lock weight is calculated in sections. Each time a lock is added, the weight will be recalculated and the expiration time will be updated to the maximum expiration time. The redemption will not be possible until the expiration time, otherwise no tokens can be redeemed;

Example 1:

The first lock-up amount is 100 and the duration is 6 months; before the first lock-up expires, at the fourth month, an additional lock-up amount is added which is 50 and the duration is 5 months, then the expiration time will be the latest . Also, the weight is recalculated as shown in the following table:

Number	Amount	Period (Month)	Time	Expiration	Weight
First Time	100	6	2022.01 ~ 2022.07	2022.07	= 100 * [(1+12/6) ^ (6/12) - 0.5] = 123.2050
Second Time	50	5	2022.06 ~ 2022.11	2022.11	= 100 * [(1+12/6) ^ (6/12) - 0.5] + 50 * [(1+12/5) ^ (5/12) - 0.5] = 123.2050 + 58.2568 = 181.4618

Example 2:

The first lock-up quantity is 100, the duration is 6 months, and it is not redeemed after the expiration; 2 months after the first lock-up expires, an additional lock is added, the quantity is 50, and the duration is 3 months, then The latest expiration time is the expiration time of the second lock-up. At this time, the weight is calculated as shown in the following table:

Number	Amount	Period (Month)	Time	Expiration	Weight
First Time	100	6	2022.01 ~ 2022.07	2022.07	= 100 * [(1+12/6) ^ (6/12) - 0.5] = 123.2050
Second Time	50	3	2022.09 ~ 2022.12	2022.12	= 100 * [(1+12/6) ^ (6/12) - 0.5] + 50 * [(1+12/3) ^ (3/12) - 0.5] = 123.2051 + 49.7674 = 172.9725
