Project PAI项目进度（2020年 4月13日）

大家好! 欢迎订阅PAI新闻第二版。在过去的一周里，不少用户参与到了PAI Coin Pool中，那就让我们从用户数据开始吧…

图1：PCP矿池的哈希率追踪

该表显示了过去一周内PAI Coin Pool的全球平均哈希率。总体而言，平均哈希速率为215 MH / 秒，相当于以标准速率运行PAI Miner的2000多个常规CPU。可以看到，几乎所有的哈希率峰值都发生在中国的白天时间，也就是大多数PCP用户所在时区。

图2：锁定权益期分布图

在目前锁定权益的6070万枚PAI币中，其中91％-约5550万枚PAI币被锁定了1年！

额外的1％被锁定权益46周，4％被锁定权益一个月，其余的则分布在其他锁定权益期。

感谢大家的踊跃参与

我们正在做

上周，团队继续对PAI Coin Pool进行优化，加入了PAI混合共识，并努力将PAI论坛迁移到新的框架中。

PAI Coin Pool

上周, 团队对于PAI Coin Pool开展优化和基础架构工作。

优化

我们除了继续致力于上周的优化工作以便支持高于预期的哈希率，还实施了更进一步的优化使平台可以随着用户群的增长而更有效，更可靠地进行扩展。

香港测试网络

我们的开发团队在香港同时建立了一个使用PAI币测试网的PAI矿池以及PAI区块链浏览器

PCP香港测试网：

https://hk-testnet.paicoinpool.com/

PAI区块链浏览器香港测试网：

https://testnet.paichain.info

本周, 我们将与您一起进行PAI Miner的连接性测试。我们计划开始实施PAI Coin Pool注册奖金和推荐系统。原计划在上周开始这项工作，但是由于香港测试网的建立造成一些延迟。最后，我们将于4月15日太平洋标准时间上午9点开始另一个提款批准期。

采矿连接性测试

我们需要您的帮助一起来测试 香港版的PAI Coin Pool。您的参与将帮助解决用户在香港的PAI Miner连接问题。为了答谢您的时间和资源，您在香港开采的任何测试网PAI币都将转换为真实的PAI币，并存入您的官方PAI Coin Pool帐户中。

功能开发

团队分享了一项通过推荐奖金，注册奖金和分层块奖励等激励措施来提高用户参与度的提案。这些功能的规划正在进行中，开发工作将于本周开始。

PAI 混合共识

PAI 混合共识是一个庞大的项目。它已经进行了很长时间了，也有了一定的进展。由于混合共识是一个开源项目，因此您可以在Project PAI的GitHub上检查最新的代码提交，欢迎在此处阅读提供建议：

https://arxiv.org/pdf/1902.02469.pdf

请记住: PAI混合共识是实现PAI币去中心化从而达到我们共同愿景的关键。

一旦启动，PAI 币使用的当前工作量证明共识机制将被混合工作量证明和权益证明协议取代。

接下来一周, 我们将发布启动PAI混合共识和进一步实现PAI区块链去中心化的的长期规划和预测。

PAI 论坛

我们正在考虑离开当前的PAI论坛技术。经过大量研究和讨论，我们选择将Discourse开源论坛软件作为PAI论坛社区的主要技术支持。

您可以在 Discourse.org 和 Github上查看开源代码库了解更多关于Discourse的信息。我们将会把现有论坛数据和用户迁移到新的Discourse平台。稍后会发布有关有关论坛过渡进度的更和重点介绍更多新论坛的功能。

PAI Pass

PAI Pass已经通过内部测试，现在已经可以将其用作Web应用程序的单点登录服务。当前的PAI Pass实施支持通过PDP2存储和检索PAI Pass用户数据。这种分散式存储功能可将加密的用户数据推送到BitTorrent网络上，解决即使PAI Pass服务器不可用，用户也可以下载其数据。

我们需要您的帮助

Project PAI的开发人员正在努力完成一项又一项惊人的项目，与此同时，我们也欢迎您一同参与，为创建PAI生态系统提出您的宝贵意见！

香港采矿测试网: PCP的工程师已经在香港开设了一个测试网站，方便测试人们在过去几周内存在的连接问题。香港测试网将使用新的单独奖励池，并且不会对主网上的采矿活动产生任何影响。

PAI Newsletter – April 13, 2020

Hi, everyone! Welcome to the second edition of the revamped PAI Newsletter. There has been a lot of engagement the past week on PAI Coin Pool, so let’s start with some stats…

Figure1: Pool hash rate over time

The chart above shows PAI Coin Pool’s global average hash rate over time for the past week. Overall, the average hash rate is 215 MH/s, equivalent to over 2000 regular CPUs running PAI Miner at its standard rate. As you can see, virtually all of the spikes in hash rate occur during daytime hours in China, where most of PCP’s users are located.

Figure 2: Distribution of staking periods

Of the 60.7 MILLION PAI Coin currently staked, 91% of it—or about 55.5 million PAI Coin—is staked for 1 year!

An additional 1% is staked for 46 weeks, 4% is staked for a month, and the rest is distributed among the other staking durations.

Now, that’s dedication!

What we’re working on

Last week, the team continued working on PAI Coin Pool optimizations, plugging away at PAI Hybrid Consensus, and began an effort to migrate PAI Forum to a new framework.

PAI Coin Pool

Last week, for PAI Coin Pool, the team focused on optimization work and infrastructure work.

Optimizations

Continuing on the previous week’s optimization work to support higher-than-expected hash rates, we have implemented further optimizations that will allow the platform to scale more efficiently and reliably as our user base grows.

Hong Kong Testnet

Our DevOps team set up a copy for both PAI Coin Pool and PAI chain explorer in Hong Kong which uses the PAI Coin testnet.

PAI Coin Pool HK testnet:

https://hk-testnet.paicoinpool.com/

PAI chain explorer HK testnet:

https://testnet.paichain.info

This week, we’ll work with YOU on PAI Miner Connectivity testing. We also plan to begin implementing the PAI Coin Pool sign-up bonus and referral system. We had originally planned to start that work last week, but the Hong Kong testnet setup delayed us a bit. Finally, we will have another withdrawal approval period starting on April 15 at 9 AM PDT.

Mining Connectivity Testing

We’ll need your help with testing the Hong Kong version of PAI Coin Pool. Your tests will confirm whether or not relocating to Hong Kong resolves the PAI Miner connectivity issues that you’ve brought to our attention. To compensate you for your time and resources, any testnet coin that you mine in Hong Kong will be converted to real PAI Coin and deposited in your official PAI Coin Pool account.

Feature Developments

The team shared a proposal for increasing user engagement via incentives like Referral Bonuses, Sign-up Bonuses, and Tiered Block Rewards. Planning for these features has been underway and development will start this week.

PAI Hybrid Consensus

PAI Hybrid Consensus is a BIG project. It’s been quietly underway for a long time, and we’re making good progress. Because Hybrid Consensus is an open-source project, you can always check the latest code commits on Project PAI’s GitHub and read the proposal here: https://arxiv.org/pdf/1902.02469.pdf

REMEMBER: PAI Hybrid Consensus is the initiative that’s key to fully decentralizing PAI Coin and realizing our collective vision.

Once launched, the current Proof-of-Work consensus mechanism that PAI Coin uses will be replaced by a Hybrid Proof-of-Work, Proof-of-Stake protocol.

In the coming weeks, we will release a long-term roadmap and projection for launching PAI Hybrid Consensus and further decentralizing the PAI Blockchain.

PAI Forum

We have considered moving away from the current PAI Forum technology for some time. After a great deal of research and discussions — the Discourse open source forum software has been selected as the new backbone for the PAI Forum community.

For more information about Discourse, you can check out Discourse.org and the Discourse open source codebase on Github. The current priority is to migrate existing forum data and users to the new Discourse platform. Upcoming newsletters will include updates about the forum transition progress as well as highlight exciting new forum features.

PAI Pass

PAI Pass has been undergoing internal testing and has now reached a stage where it can be used as a single-sign-on service for web applications. The current PAI Pass implementation supports storage and retrieval of PAI Pass user data via PDP2. This decentralized storage feature pushes encrypted user data to a BitTorrent network — so that users can download their data even if PAI Pass servers are unavailable.

What YOU Can Do To Help

While the developers at Project PAI are hard at work on these amazing projects, here are some opportunities for you to provide feedback and participate in the PAI Ecosystem!

Hong Kong Testnet Mining: The engineers at PCP have opened up a test website based in Hong Kong to test mining connectivity issues people have been reporting over the past few weeks. The Hong Kong testnet will be using a new separate reward pool, and will not have any effect on mining activity on the Mainnet.

PAI Up Web Wallet Testing: The PAI Up Web Wallet is a new way for users to be able to access their PAI Coin beyond their mobile devices. Project PAI is looking for testers to try out the platform and provide feedback. Check out the PAI Forum post to participate:

https://www.paiforum.com/post/pai-up-web-wallet-testing-is-available

Internet Latency Test: Over the past few weeks, we’ve been getting feedback on some issues with connecting to some PAI initiatives, such as PAI Coin Pool and using the PAI Miner software. Project PAI is looking into solutions for improving network connectivity for the community, with the first of these being an Internet Connectivity Test you can be involved in! Check out the PAI Forum post to participate:
