2020/3/12 Pi Network 項目核心團隊再度發表新的公告視頻及文稿，詳細說明 Pi Network 項目的去中心化網絡和貨幣、電腦架設節點定位(排除手機)、安全圈和安全網運作、擴大的 KYC (身分認證)範圍、測試節點的挑選。
公告亮點解析：
一、去中心化貨幣最終將由開拓者(先鋒)的分佈式全球網絡保護，而不是由一個集中的實體控制。
定調 Pi Network 的去中心化網絡，由開拓者共同自治維護(社區管理)。
二、開拓者(先鋒)可以像比特幣和以太坊一樣不受中心化干擾地自由出售或交換 Pi 幣。
除了商品和服務交易， Pi 可以與其他貨幣自由交易。
三、節點將替代手機在筆記型電腦和桌上型電腦上運行。
開拓者(先鋒)可以選擇設立節點，設立需經過 KYC 及申請核可。
四、開拓者(先鋒)可以為運作中的節點選擇打開或關閉，使設備處於可用或不可用狀態。
意味著關閉的節點會有軟體自動橋接其他運作中的節點及配對安全網，不需要24小時運行。
五、在2020年3月31日，我們將提供 Pi 節點應用程序的初始版本供下載和安裝。
節點有包括兩個界面：節點界面和電腦桌面 Pi 界面。允許檢查其 Pi 餘額並在其個人計算機上使用 Pi 聊天。六、將開設更多的 KYC 機制來支援節點的註冊和測試網的發展。
擴大 KYC 範圍，增加測試節點數量。
At Pi Network, we believe that everyday people should have a greater voice and capture a greater share of the value that they create in society.
We believe that the best way to achieve this goal is by building a decentralized currency and economy.
在 Pi Network，我們相信每天的人們應該擁有更大的發言權，並在他們創造的社會價值中獲得更大的份額。
我們認為，實現這一目標的最佳方法是建立去中心化的貨幣和經濟。
Pi’s decentralized currency will eventually be secured by a distributed global network of Pioneers, rather than being controlled by one single centralized entity.
Pi’s global network will be ultimately self-governed, meaning that the community can shape how Pi evolves over time.
Pi 的去中心化貨幣最終將由開拓者(先鋒)的分佈式全球網絡保護，而不是由一個集中的實體控制。
Pi 的全球網絡最終將實現自治，這意味著社區可以決定 Pi 隨時間的發展方式。
When Pi is fully decentralized, Pioneers will also have full sovereignty and control over their own cryptocurrency holdings.
Progress in decentralization brings Pi closer to the phase where Pioneers will be able to sell or exchange Pi, without centralized interference, just like bitcoin and ethereum.
In other words, moving into the Phase 2, the testnet phase, takes us one step closer to Mainnet, when Pi can be traded freely with other currencies, in addition to trading for goods and services.
當Pi完全去中心化時，開拓者(先鋒)也將擁有完全的主權並控制自己的加密貨幣持有量。
權力下放的進展使 Pi 更加接近開拓者(先鋒)可以像比特幣和以太坊一樣不受中心化干擾地自由出售或交換 Pi 的階段。
換句話說，進入第二階段，即測試網階段，使我們比Mainnet(主網)更近一步，那時 Pi 可以與其他貨幣自由交易，除了商品和服務交易。
Pioneers who want to help secure Pi’s currency can choose to become a Node.
希望幫助保護 Pi 貨幣的開拓者(先鋒)可以選擇成為節點。
Nodes are the forth role in the Pi ecosystem, and run on laptops and desktops instead of mobile phones.
Similar to other blockchains, Pi Nodes will be responsible for validating transactions on a distributed ledger, and resolve the challenges in maintaining a distributed currency by having all nodes come to a “consensus” on the order of new transactions getting recorded.
節點是 Pi 生態系統中的第四個任務，將替代手機在筆記型電腦和桌上型電腦上運行。
與其他區塊鏈類似，Pi 節點將負責驗證分佈式分類賬上的交易，並通過讓所有節點都記錄新交易的順序達成「共識」，從而解決維護分佈式貨幣方面的挑戰。
Unlike nodes that use proof of work such as Bitcoin or Ethereum, Pi Node uses a different consensus algorithm based on the Stellar Consensus Protocol, in which nodes form trusted groups (quorum slicess) and only agree to transactions that those trusted nodes agree to.
The security circles from Pi mobile miners aggregate into a global trust graph that enables Pi nodes to form quorum slices to determine who can and cannot validate transactions on the shared ledger.
與使用工作量證明（例如比特幣或以太坊）的節點不同，Pi 節點 使用基於恆星共識協議的不同共識算法，其中節點形成受信任圈（仲裁切片），並且僅同意那些受信任信節點所同意的交易。
Pi 移動礦工的安全圈匯總到一個全局信任圖中，該圖使 Pi 節點可以形成仲裁切片，以確定誰可以和不能驗證共享分類賬上的交易。
Also unlike other crypto projects, the Pi Node will continue to uphold the philosophy of user centric design.
Instead of requiring much technical knowledge to set up a node, everyday people will be able to do that by installing a desktop application on their computers, just like installing any other computer app.
Through this desktop application, Pioneers can switch on/off to make their devices available/unavailable for serving as a node.
與其他加密貨幣項目不同，Pi 節點將繼續秉承以用戶為中心的設計理念。
不需要太多的技術知識來建立節點，每天人們都可以通過在計算機上安裝的桌面應用程式來達成，就像安裝其他任何計算機應用程式一樣。
通過此桌面應用程式，開拓者(先鋒)可以為運作中的節點選擇打開或關閉，使設備處於可用或不可用狀態。
By March 31, 2020, we’ll make the initial version of the Pi Node application available to download and install.
This initial version of the Node will include two interfaces:
the node interface and the desktop Pi interface.
The desktop Pi interface will be similar to the interface of the mobile app and will allow people to check their Pi balance and use the Pi chats on their personal computer.
在2020年3月31日，我們將提供 Pi 節點應用程序的初始版本供下載和安裝。
該節點的初始版本將包括兩個界面：
節點界面和電腦桌面 Pi 界面。
電腦桌面 Pi 界面將類似於移動應用程序的界面，允許人們檢查其 Pi 餘額並在其個人計算機上使用 Pi 聊天。
However, only members, who apply and get selected by the core team to serve as a testnet node, will have the node interface fully activated.
The detailed requirements and selection process will be announced along with the software launch.
然而，只有申請通過並由核心團隊選擇成為測試網節點的成員才能完全激活節點接口。
詳細要求和選擇過程將與軟件發布一起宣布。
This version of the node is the first step towards building the Pi Testnet, which will enable the core team to test the consensus algorithm and its scalability, calibrate configurations, and adapt and improve the consensus algorithm.
Pioneers who run this version of the node will not need to be concerned with such processes.
All they need to do is to decide if and when their devices are available/unavailable serving as a node in the Pi testnet, if they’re selected as a node.
此節點版本是構建 Pi Testnet(測試節點)的第一步，它將使核心團隊能夠測試共識算法及其可擴展性，校準配置以及適應和改進共識算法。
運行此版本節點的開拓者(先鋒)將不必擔心此類過程。
他們要做的就是確定是否將其設備選為節點，以及何時將其設備用於 Pi 測試網中的節點。
The Nodes for Pi’s Testnet will be launched and open for application by 3/31/2020.
In order to be selected to run certain versions of the node on Pi’s Testnet, Pioneers will have to undergo KYC.
More KYC slots will be opened up to support node enrollment and the advancement of Testnet.
More detailed selection criteria for Pi Node will be released along with the software launch.
But overall, the principles of node selection will be the trustworthiness in the network, and the availability and reliability of the device.
Pi 的測試網節點將在2020年3月31日啟動並開放供下載應用程式。
為了能夠在 Pi 的測試網上運行該節點的某些版本，開拓者(先鋒)必須通過 KYC(身分認證)。
將開設更多的 KYC 機制來支援節點的註冊和測試網的發展。
Pi 節點的更詳細選擇規範將隨軟體啟動一起釋放。
但是總的來說，節點選擇的原則取決於網絡中的可信度以及設備的可用性和可靠性。
