最新消息Pi Network(Pi币)官方公布关于第二阶段的Pi节点:在Pi网络中建立节点,不是人人都能被选上,但人人都有机会

Pi Phase 2 - Pi Nodes
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.


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.


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.

Pioneers who want to help secure Pi’s currency can choose to become a Node.


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.

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.

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.

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. 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.


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.


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阶段2 - Pi节点









与使用比特币或Ethereum等工作证明的节点不同,Pi节点使用基于恒星一致协议的不同一致算法,其中节点形成可信组(quorum slicess),只同意那些可信节点同意的交易。来自Pi mobile miners的安全圈聚合成一个全局信任图,该图使Pi节点能够形成quorum片,以确定谁能够和谁不能验证共享分类帐上的交易。



这个版本的节点是构建Pi Testnet的第一步,它将使核心团队能够测试consensus算法及其可伸缩性、校准配置、调整和改进consensus算法。运行这个版本的节点的先驱者将不需要关心这样的过程。他们所需要做的就是决定他们的设备是否以及何时可用/不可用,作为Pi testnet中的一个节点,如果它们被选择为一个节点的话。
