搭建PAI节点激励计划

在电子邮件中,填写完整节点的IP地址或URL。我们将回复有关如何领取奖励的更多说明。

在PAI币池上质押

在PAI币池上的质押是通过称为”代理”的机制进行的。通过将所有质押的用户资金集中在一起来进行代理权益凭证购买,以在PAI区块链上购买更多和更高价值的权益凭证。然后,将奖励按比例分配给利益相关者。这种机制对于可能没有足够的PAI来自己购买至少一个权益凭证的用户特别有利(例如,当权益凭证的价格太高时)。另一方面,当权益凭证价格较低时,拥有大量资金几乎没有优势,因为根据规则,整个网络上可以购买的权益凭证的总数限制为20个。因此,随着权益凭证价格的上涨,与PCP质押相关的优势(和奖励金额)将大大增加。让我们通过示例进行更深入的研究,以确保最大化用户利益和公平性。

对于一些PAI币HODLers(持有者)

想象以下的每个人决定以指定PAI币选择单独质押,或将其质押到PCP上。

Project PAI 项目进度- 2020年11月18日

请注意,上面的这张表等效于下表,因为PAI币池上的所有质押者实际上都构成一个PCP质押者。

Project PAI 项目进度- 2020年11月18日

初始情况

在PAI区块链首次执行混合共识硬分叉时,初始权益凭证价格设置为只有2个PAI币。设置此低值是为了鼓励以低价快速购买权益凭证,以增加实时权益凭证的数量并确保区块链的平稳功能。目标是在任何给定时间维持40,960张实时权益凭证。如果购买的权益凭证数量导致总数超过40,960,则SV的价格将自动上涨;相反,如果购买的SV的数量导致总数下降到40,960以下,则SV的价格将自动降低。

因此,在SV价格为2PAI的情况下,在上述5个HODLer场景中会发生什么:Alice,Bob,Carol,Charlie和PCP。首先,请记住,如果一个SV的价格为2 PAI币,整个网络中任何人和每个人可以购买的SV总数为20。就意味着:

a. 每一个人每块可以独立质押的最低权益凭证的金额始终等于一张权益凭证的价格,在这种情况下为2 PAI币。

b. 所有人总共可以在每个区块中质押的PAI代币的总金额是单个权益凭证价格的20倍,在这种情况下为40 PAI币。

随之而来的是,如果每个SV的价格很低的话,拥有大量的PAI币就几乎没有优势,因为在这种情况下,区块链网络允许您投入的最大金额非常低。尽管这可能违反直觉,但在这种情况下,每块20个可用的权益凭证将在5个利益相关者(Alice, Bob, Carol, Charlie和PCP)之间平均分配;尽管事实是,PCP中人均持有的PAI币数量是其他独立质押的人中最多质押PAI币数量的200倍。但是,这种情况是仅仅一个非常临时的状态,并且已经得到解决。

权益凭证(SV)的当前价格

自从PAI区块链混合共识机制的权益凭证自推出以来,权益凭证的价格已从最初的2 PAI 增加到当前(周报发布前)的每SV约12,684 PAI的价格(如下图所示)。当活跃SV的数量接近40,960的目标时,SV的价格开始从区块高度158,000的附近呈指数增长。以当前每SV的价格为12,684 PAI币,任何一个人可以质押的最小PAI币数量为12,684 PAI,任何人和其他人总共在每个区块可以质押的PAI币总量为253,680 PAI。重新考虑我们的HODLers,我们发现表格中Alice, Bob和Carol这三个人的节点现在已经负担不起独立质押的SV价格。在这种情况,每个区块的20个SV将只能分配给Charlie和PAI币池了。

下图反映了自从PAI混合共识硬分叉以来的SV的价格趋势和活跃SV的数量:

图3:活跃的SV数量(横轴为区块高度,纵轴为活跃的SV数量)

未来的权益凭证(SV)价格

随着时间的流逝,相对于其他参与者,PAI Coin Pool能够积累越来越多的权益凭证(很大程度上是由于凭证价格上涨),PCP权益承担者之间分配的相应奖励幅度将增加。奖励何时以及增加多少的时间很难预测,但是如上图所示,单个权益凭证的价格现在正呈指数增长。

在上述假设情况下,一旦SV价格超过100,000 PAI,除PCP之外的任何网络参与者都将很难购买权益凭证,届时每个区块将大部分SV分配给PCP。此外,凭借1亿PAI的购买力,PCP可以继续购买价值越来越高的权益凭证,这使得其他质押者越来越难以负担独立质押的SV价格。正是在这一点上,将实现PCP质押的优势和收益。

如何将PAI Up Mobile连接到特定节点?

如果无法同步PAI Up或您的PAI电子钱包在同步后仍然显示不正确的数据,将如何解决?

微信等传统应用程序通过连接到中央服务器,以检索和上传新数据,例如传入和传出消息,或来自其他用户的新时刻。PAI Up不能那样工作。由于PAI区块链是分散的去中心化网络,因此没有中央服务器。但是每个PAI币全节点都像一个中央服务器,并且当您启动PAI Up时,该应用程序必须(基本上是随机地)选择要连接的完整节点。

如果您与该节点的连接较差(例如,由于其物理距离较远),或者该节点发生问题(例如,由于其所有者未正确维护它),则PAI Up可能无法正常工作。在这种情况下,您应该手动重新连接到其他节点。下面是教程:

从PAI的主屏幕上→ 菜单 → 首选项 → PAI币设置 → PAI币节点。

现在,记下”当前主节点”,然后选择”切换到手动模式”。从那里,在顶部字段中输入以下节点之一(与上一个屏幕中的”当前主节点”不匹配),然后选择”确定”。您可以直接输入URL或IP地址。 然后,确保”节点连接状态”显示为”已连接”。如果不是,或者在”已连接”和”正在连接”之间,请从下面的列表中选择一个不同的节点,然后重复该过程。

Staking on PAI Coin Pool

Staking on PAI Coin Pool works via a mechanism called Staking By Proxy. Staking By Proxy functions by pooling together all staked user funds in order to purchase more and higher-valued stake vouchers on the PAI Blockchain. Rewards are then distributed among stakers proportional to the amount their stake contributed to the pool. This mechanism is particularly beneficial for users who may not own enough PAI to purchase at least one stake voucher on their own, e.g., because the stake voucher price is too high. On the other hand, when the stake voucher price is low, there is little advantage to having a large pool of funds, since, by rule, the total number of stake vouchers that can be purchased across the entire network is limited to 20. So, as the stake voucher price increases, the advantages (and reward amounts) associated with PCP staking will increase substantially. Let’s take a deeper look by example.

Some PAI Coin HODLers

Imagine that the following individuals have decided to either solo stake or stake their PAI Coin on PCP in the specified amounts.

Project PAI 项目进度- 2020年11月18日

Note that this is equivalent to the following table, because all of the stakers on PAI Coin Pool effectively form one single PCP staker.

Project PAI 项目进度- 2020年11月18日

Initial Stake Voucher Price

When the hybrid consensus fork was first executed, the initial stake voucher price was set to only 2 PAI Coin. It was set this low to encourage rapid purchasing of stake vouchers at a low price to build up the number of live stake vouchers and ensure smooth functionality of the blockchain. The goal is to maintain 40,960 live stake vouchers at any given time. If the number of stake vouchers being purchased will cause the total number to exceed 40,960, the price of an SV will automatically increase; inversely, if the number of SVs being purchased causes the total number to drop below 40,960, then the price of an SV will automatically decrease.

So, at an SV price point of 2 PAI, what happens in the above scenario of the 5 HODLers: Alice, Bob, Carol, Charlie, and PCP? First, let’s remember, the price of one SV is 2 PAI Coin, and as always, the total number of SVs that can be purchased by anyone and everyone combined across the entire network is 20. This means that:

a.The minimum amount any one individual can solo stake per block is always equal to the price of a single stake voucher, in this case, 2 PAI Coin.

b.The total amount of PAI Coin that can be staked per block by anyone and everyone combined is 20 times the price of a single stake voucher, in this case, 40 PAI Coin.

It follows then, that at this low of a price per SV, there is little advantage to owning a substantial amount of PAI Coin, because the maximum amount the network will allow you to stake in this scenario is very low. While it may be counterintuitive, in this case, the 20 available stake vouchers per block will be split evenly among the 5 stakeholders: Alice, Bob, Carol, Charlie, and PCP; and this is despite the fact that PCP holds 200 times the amount of PAI Coin as the next richest staker. This situation, however, is very temporary.

Current Stake Voucher Price

Since the launch of Hybrid Consensus, the stake voucher price has increased from the initial 2 PAI to its current price (as of writing) of approximately 12,684 PAI per SV. As shown in the charts below, the SV price began to exponentially increase around block height 158,000, when the number of live stake vouchers approached the target of 40,960. At the current price of 12,684 PAI per SV, then, the minimum amount of PAI Coin that any one individual can stake per block is 12,684 PAI, and the total amount of PAI Coin that can be staked per block by anyone and everyone combined is 253,680 PAI. Reconsidering our HODLers, we see that Alice, Bob, and Carol are all now unable to afford solo staking, so the 20 SVs available per block would be split between Charlie and PAI Coin Pool only.

Future Stake Voucher Price

As time goes on, and PAI Coin Pool is able to accumulate more and more stake vouchers relative to other participants (helped in large part by the increasing price of a voucher), the corresponding magnitude of the rewards distributed among PCP stakers will increase. The timing of when and by how much the rewards will increase is difficult to predict, but as you can see by the chart above, the price of a single stake voucher is now increasing exponentially.

In the hypothetical scenario above, once the SV price exceeds 100,000 PAI, no network participants other than PCP will be able to afford to purchase stake vouchers, and all 20 of them, per block, would be allocated to PCP. Further, with a purchasing power of 100 million PAI, PCP could continue to purchase stake vouchers of increasingly higher value, rendering it more and more difficult for other stakers to be able to afford to participate independently. It is at this point that the advantages and profitability of PCP staking will be realized.

How to connect PAI Up Mobile to a specific node?

Follow these instructions if you are unable to sync PAI Up or if your PAI Wallet still displays incorrect data after a sync.

Traditional apps, like WeChat, connect to a central server to retrieve and upload new data like incoming and outgoing messages, or new Moments from other users. PAI Up doesn’t work like that. Since the PAI Blockchain is a decentralized peer-to-peer network, there is no central server. But every PAI Coin Full Node acts like a central server, and when you launch PAI Up, the app has to choose—basically, at random—which Full Node to connect to.

If your connection to the node is poor (for example, because it’s physically far away), or there happens to be something wrong with that node (for example, because its owner is not properly maintaining it), PAI Up might not work well. In this case, you should manually reconnect to a different node. Here’s how.

From the main screen of PAI Up → Menu → Preferences → PAI Coin Settings → PAI Coin Nodes.

Now, take note of the “Current Primary Node,” then choose “Switch to Manual Mode.” From there, enter one of the following nodes (one that doesn’t match the Current Primary Node from the previous screen) in the top field and choose “OK.” You can enter either the URL or the IP address directly. Then, make sure the “Node Connection Status” shows “Connected.” If it doesn’t, or if it oscillates between “Connected” and “Connecting,” choose a different node from the list below and repeat the process.
