Project PAI 项目进度- 2020年11月23日

公告和信息

PAI区块链主网 2.1.0 版推出了！快来更新吧。

如果您正在运行完整节点，独立质押和/或独立挖矿，则必须立即更新到2.1.0

如要更新，请在完整节点的paicoin目录中执行以下命令：

paicoin-cli stop ＃停止节点当前运行

git pull ＃从paicoin仓库中获取最新变化

git checkout 2.1.0 ＃切换到最新版本

make clean ＃卸载以前的版本

make ＃编译新版本

sudo make install ＃在系统级别安装

paicoind ＃重新启动您的节点

对于所有独立质押者：请确保您的节点在线并具有投票权！

请在您的质押节点上执行以下脚本：

方法如下：

1. 在下面的链接下载脚本：

https://paicoin-scripts.s3.ap-east-1.amazonaws.com/voter_check.py

2. 然后您可以：

a. 将脚本上传到用于质押的完整节点，或者；

b. 将其内容复制并粘贴到名为 voter_check.py 的完整节点上的新文件中。

3. 运行以下命令以正确的依赖关系执行脚本（这些命令假定 voter_check.py 和 paicoin 目录都位于用户主目录中（〜），并且您的用户主目录是您当前的工作目录 pwd）：

sudo apt install python3

cd paicoin

sudo make install

cd ..

python3 voter_check.py

搭建PAI节点激励计划

设置一个完整的节点并获得666 PAI的PAI Coin Pool 奖金！请根据此教程搭建完整节点，然后请您用与您的PCP帐户相关联的电子邮件地址发送电子邮件至：

promotions@projectpai.com

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。想了解更多信息，请参阅上周的周报。

PAI币池权益凭证统计数据

●当前权益凭证价格：29,663 PAI

●PAI币池拥有的实时权益凭证百分比：29％

●实时凭证：69,243

●权益凭证总数，PAI代币池获得的质押权奖励总额：137万PAI

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。

如果这些仍然无效，请您尝试卸载并重新安装PAI Up。

PAI News – November 23, 2020

Announcements & Reminders

PAI Coin 2.1.0 is here! UPDATE TODAY.

If you are running a full node, solo staking, and/or solo mining, you must immediately update to 2.1.0.

To update, execute the following commands in the paicoin directory of your full node.

paicoin-cli stop # stop the node from currently running

git pull # pull the latest changes from the paicoin repo

git checkout 2.1.0 # switch to the latest release

make clean # uninstall your previous build

make # compile the new release

sudo make install # install at the system level

paicoind # restart your node

For ALL solo stakers: Make sure your node is online and voting!

Execute this script on your staking node.

Here’s how:

1.Download the script from here.

https://paicoin-scripts.s3.ap-east-1.amazonaws.com/voter_check.py

2.Either:

a.Upload the script to the full node you use for staking, or;

b.Copy and paste its contents into a new file on the full node named voter_check.py

3.Run the following commands to execute the script with the correct dependencies (these commands assume that voter_check.py and your paicoin directory are both located in your user home directory (~), and that your user home directory is your present working directory, pwd):

sudo apt install python3

cd paicoin

sudo make install

cd ..

python3 voter_check.py

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. For more information, seelast week’s newsletter.

PAI Coin Pool Stake Voucher Stats

●Current Stake Voucher Price: 29,663 PAI

●Percentage of live Stake Vouchers owned by PAI Coin Pool: 29%

●Total number of live Stake Vouchers: 69,243

●Total amount of stake rewards earned by PAI Coin Pool to date: 1.37 million PAI

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.
