02常见问题（持续更新）

PAI Coin Pool

PAI Coin Pool的推荐系统如何工作？

PAI Coin Pool 推荐系统会为推荐其他人前来注册并参与PAI Coin Pool的用户提供分等级奖励。

上图为您详细说明了一个针对11个用户的推荐系统的概念演示，这些用户都是全部被用户A直接或间接地推荐的。我们将以示例的方式具体描述该系统的工作方式。

假设用户A推荐给用户B、C和D。用户A可以通过电子邮件或任何其他短信服务，例如微信，Line，Kakao 或 Facebook, 发送链接向他们进行推荐，该链接包含了一个唯一代码，例如:

https://paicoinpool.com/auth/sign-up?referralCode=….。

该链接可以直接前往PCP控制面板上的”个人资料”页面获得。当用户访问此链接并成功创建新的PAI Coin Pool帐户时，则视为推荐完成。接下来，用户B推荐给用户E和F，用户C推荐给用户G，H和I，最后，用户D推荐给用户J和K。

由此我们可以得到上图的推荐链说明，因为用户A直接推荐了用户B，C和D，用户A将有资格根据他们的采矿和权益活动获得第1层推荐奖励；接下来，用户A可以获得第2层基于用户E，F，G，H，I，J和K的采矿和权益活动的推荐奖励，因为他们都是由最初用户A推荐的用户所推荐的。同理，用户B将有资格获得基于用户E和F的采矿和权益活动的推荐奖励；用户C将有资格获得基于用户G，H和I的采矿和权益活动的推荐奖励；用户D将有资格获得基于用户J＆K的采矿和权益活动的推荐奖励。

（图1 ：PAI Coin Pool 资料页面上的推荐码示例）

（图2 ：推荐人所获得的推荐奖励）

（图3：被推荐用户产生的采矿收益。图2中所获得的推荐奖励是被推荐用户产生收入的10％）

下面的图表所展示的是一个假设情景，假设每个用户在一天内可以根据自己和他人的采矿和权益活动总和来计算出他可以赚取多少。

从上述的表格和图表中可以看出，即使用户A一天都没有进行采矿或权益，仅根据用户B，C和D的采矿和权益活动，他就可以获得600多枚PAI币。同样，基于用户E到K，用户B，C和D也获得了额外奖励，其中包括900多个PAI币，这远远超过了他们自己从采矿和权益中获得的收益。另外，请记住：虽然用户E到K没有获得任何推荐奖励，但他们自己的采矿和权益收入也不会因为用户A到D的推荐奖励而减少。

这就是PCP推荐系统的工作方式。参与推荐的过程将可以帮助您通过额外的系统推荐奖励（通过发送链接推荐他人）增加您的收入。

什么是PAI Coin Pool 注册奖励？

注册奖励是新用户可以通过在特定优惠期内注册PAI Coin Pool账号，并挖掘或权益达到规定的最低金额，即可获得额外PAI币奖励。

举个例子，PAI Coin Pool 可能在某个星期的星期一至星期三进行优惠活动。如果新用户在其中的某一天注册了新帐户并且只要满足指定条件，就有资格获得 100 PAI币的额外奖励。该标准将基于在某一规定时间段内权益最低数量的PAI币，或开采最少数量的幸运哈希。例如，系统要求新用户在26周内锁定权益达到至少 1000PAI 币从而解锁注册奖励。或者在采矿的情况下，要求他们开采至少100,000个幸运哈希来获得该奖励。

PAI Coin Pool将定期进行优惠活动吸引更多新用户使用PAI Coin Pool。

Frequently Asked Questions

PAI Coin Pool

How does PAI Coin Pool’s Referral System work?

The PAI Coin Pool Referral System offers tiered rewards for users that recommend, or “refer,” others to sign up for and participate in PAI Coin Pool.

The diagram above illustrates the concept of the referral system for a collection of 11 users who were all directly or indirectly referred by User A. We’ll describe how the system works by way of example.

Suppose User A refers Users B, C, and D. He does this by sending a link to them via email of any prefered messenger service such as WeChat, Line, Kakao or Facebook, which contains a unique code like

https://paicoinpool.com/auth/sign-up?referralCode=….

The link will be accessible from your Profile page on the PCP Dashboard. The referral is complete when a user visits the URL and successfully creates a new PAI Coin Pool account). Next, User B refers Users E & F, User C refers Users G, H, and I, and finally, User D refers Users J & K.

Out of this chain of referrals, we get the above diagram, where User A is eligible to receive Tier 1 Referral Rewards based on the mining and staking activities of Users B, C, and D—because User A referred them directly—and Tier 2 Referral Rewards based on the mining and staking activities of Users E, F, G, H, I, J, and K—because they were all referred by users originally referred by User A. Users B is eligible to receive Tier 1 Rewards based on the mining and staking activities of Users E & F; User C based on G, H, and I; and User D based on J & K.

This following table shows a hypothetical scenario of how much each user might earn based on their own and others’ mining and staking over the course of one day.

From the above table and graph, you can see that, even though User A did not mine or stake at all that day, he earned over 600 PAI Coins simply based on the mining and staking activity of Users B, C, and D. Similarly, based on Users E through K, Users B, C, and D earned additional awards totaling over 900 PAI Coins among them—and that’s above and beyond what they earned from their own mining and staking. Also, keep in mind: While Users E through K didn’t earn any referral rewards, none of their own mining and staking earnings were reduced due to the referral rewards of Users A through D.

So, that’s how the PCP Referral System works. Hopefully, you can see from this example that participating in the referral process increases your earning potential by unlocking additional rewards that you can get just by sending out a link.

What are PAI Coin Pool Sign-Up Bonuses?

Sign-up bonuses are additional PAI Coin rewards that new users can earn by signing up for PAI Coin Pool during a specific promotional period and mining or staking at least some minimum amount.

For example, PAI Coin Pool might run a promotional campaign from Monday to Wednesday of a certain week. If a new user creates an account on one of those days, they’ll be eligible to earn a bonus of, say, 100 PAI Coin, once they meet certain criteria. The criteria will be based on staking at least a minimum amount of PAI Coin for a length of time, or mining at least a minimum number of Lucky Hashes. For example, the new users might be required to stake at least 1000 PAI Coin for 26 weeks to unlock the bonus. Or, in the case of mining, they might be required to mine at least 100,000 Lucky Hashes to earn the reward.

PAI Coin Pool will regularly run promotions to draw new users to PAI Coin Pool.

In next week’s Newsletter, we’ll answer more questions about PAI Hybrid Consensus and Proof of Useful Work. And remember — If there’s something else you want to know, just ask on PAI Forum! Now, for some updates…
