以下是我们白皮书中路线图章节的新草案。它回顾了网络的前两个阶段（ Beta 和 Test net ），并更详细地介绍了 Mainnet 阶段。欢迎您的反馈，然后我们更新的官方白皮书在我们的网站时，开放网络开始。请记住，我们也正在制定其他白皮书章节的新草案，并将很快发布，这将可能进一步澄清您现在可能有的问题。
路标Pi Network 在我们的技术和生态系统设计上是独一无二的，我们的社区投入对发展也有重要意义。这种独特性最好通过一种深思熟虑的迭代方法来实现，这种方法允许社区反馈、产品测试、功能和用户体验，以及由里程碑定义的阶段。我们的发展分为三个主要阶段:( 1 )测试版，( 2 )测试网，( 3 )主网。 第一阶段：测试版2018 年 12 月，我们在 iOS 应用商店上公开推出了我们的移动应用程序，作为最初的先驱者的 alpha 原型。2019 年 3 月 14 日，圆周率日，原始圆周率白皮书发表，标志着圆周率网络正式上线。在这个阶段，我们的 APP 通过对未来的增长和安全的贡献，让先锋们挖掘 Pi圆周率区块链。由于最终的目标是推出 Mainnet ，并围绕 Pi 平台建立一个生态系统，运行在集中式 Pi 服务器上的 Pi 应用程序使手机用户（ Pioneers ）能够贡献他们的安全圈子，总的来说，构建了 Pi Blockchain 的共识算法所需的信任图，作为回报，先锋队获得了挖矿奖励。此外，集中化阶段允许网络增长，社区形成， Pi 令牌可访问和广泛分发。这个阶段还允许通过在整个开发过程中利用社区的投入来迭代许多技术特性和先锋经验。 在测试阶段取得了以下主要成就：
第二阶段：测试网这个阶段从 2020 年 3 月 14 日开始，标志着向去中心化区块链过渡的另一个关键准备——一个拥有来自世界各地分布式节点的直播 Test net 。Pi Network 的 Node 软件使个人计算机能够支持使用 Test - Pi 硬币运行 Pi Test net 。Test - Pi 仅用于测试，与 Pi 上的先锋帐户余额无关Pi Test net 已经达到了 10 , 000 多个全功能社区节点和超过 100 , 000 个在等待列表上的每日活动节点，并且正如在后面一节中所解释的，将继续存在于 Mainnet 阶段的测试目的。 Pi Test net 允许测试区块链的连接性、性能、安全性和可扩展性，并允许 Pi 应用开发者在可以将其应用部署在 Main net 上之前开发 Pi APP 。在 Test net 阶段，采用了 3 个主要策略：（ 1 ）通过 Testnet 节点进行去中心化，（ 2 ）通过主要的 Pi 应用程序进行移动挖掘的增长，（ 3 ）通过 Pi 浏览器上的应用程序平台进行效用创建。Test net 与第一阶段的 Pi 移动挖掘应用程序并行运行，并使分散的社区节点能够上网并为 Main net 做好准备。具体来说， Test net 节点帮助评估区块链的性能、安全性和可扩展性。它还帮助 Pi App 开发者针对 Pi 区块链测试他们的应用。与此同时， Pi 移动挖矿应用继续搭载数百万 Pioneers ，构建社区，为区块链的安全做出贡献。Pi 浏览器，随着 PiSDK,使社区能够创建实用工具和开发 Pi 生态系统。 在测试网阶段取得了以下主要成就：
第三阶段：主网2021 年 12 月， Pi 区块链的 Main net 将上线。先锋余额从他们的电话帐户迁移到 Mainnet 在此期间开始。先行者的 KYC 认证在他们的余额迁移到主网之前。为了让数以百万计的先驱有足够的时间来顺利完成他们的KYC验证，在 Pi 生态系统中创建实用程序，继续迭代我们的技术和生态系统设计， Main net 将有两个阶段：
封闭网络期这一时期将从 2021 年 12 月开始。封闭网络期间意味着主网是活的。但是有防火墙可以防止任何不必要的外部连接。拓荒者可以花时间KYC并将他们的 Pi 迁移到活跃的 Mainnet 区块链上。迁移到 Mainnet 的任何余额都可以通过 Pioneer 的选择来使用，在 Pi 应用中购买商品和服务，转移到其他先锋，或者被锁定一段时间以获得更高的挖矿率。KYC ‘ ed 先锋将能够在 Pi 网络内的封闭环境中自由地在 Main net 上使用他们的 Pi 。然而，这一时期将不允许 Pi 区块链和其他区块链之间的连接。 两阶段法在主网中的优势有一个中间封闭的时期斜坡到完全开放的 main net 有多种优势。这一方法允许：
封闭的网络期间允许数百万先驱者进入KYC，并将他们的PI迁移到Mainnet。只有一小部分先驱者能够在Mainnet发射前后完成他们的KYC。在未来的几个月里，我们将继续向更多的先驱者推出KYC解决方案，并帮助他们完成他们的KYC。如果我们直接从Testnet转移到Open Network，这意味着先驱者在其他人之前就可以使用PI平台之外的PI，而那些仍在等待完成KYC的先驱者还没有这个特权。世界各地的先驱者完成其KYC的速度将取决于每个地方社区提供KYC验证者群众工作队伍的速度以及个别先锋参加KYC的速度。 “封闭网络”时期给了数以百万计的先驱者时间去完成他们的KYC然后把他们的派传送到主网这样，所有愿意并能够完成他们的KYC在一段合理的时间内马上就可以使用 Pi 平台之外的 Pi鉴于 Pi 区块链和其他区块链或系统之间的外部连接在封闭网络期间是不允许的，这进一步帮助先锋专注于过渡到 Mainnet ，而不受 Pi 区块链外部的任何影响。 这段时间还将帮助社区专注于创建实用程序和引导生态系统，而不受任何外部干扰。与 Pi 网络实现基于实用工具的生态系统的愿景一致，这允许应用程序在 Mainnet 上部署，并为 Pioneers 创建实用工具。Pi 应用程序将能够从 Test net 切换到 Main net ——切换到真正的 Pi 交易的生产模式。在这个时候， KYC ‘ ed 的先锋们将能够把他们的 Pi 花在 Pi 应用上，促进实用程序的创建，并在开放网络之前引导 Pi 生态系统。这种逐渐和刻意的斜坡开放网络将帮助应用程序，以及圆周率网络，发现和解决任何故障在市场和技术。因此，封闭网络时期符合 Pi 的基于功利的生态系统及其迭代哲学的愿景。 此外，封闭网络将允许 Main net 与生产数据和真实的 Pi 一起运行，这与 Test net 不同。在封闭网络收集的数据将有助于校准和调整任何配置和公式，如果必要的话，以确保一个稳定和成功的开放网络。 KYC 验证和主网络余额转移“认识你的客户”(KYC)是一个验证身份的过程，以区分真假帐户。派网络的愿景是为所有先锋建立一个包容性最强、分布最广的令牌和生态系统。Pi Network 的挖掘机制是基于社交网络的，当社交网络规模增长到 1K 、 10K 、 100K 、 1M 和 10M 以上时，挖掘率下降了 5 倍。因此， Pi 有严格的每人一个 Account 的政策。这就要求有很高的准确度，以确立网络中的成员是不是地地道道的人类，防止个人通过创建虚假账户来不公平地囤积 Pi 。先锋队KYC结果不仅取决于身份验证，还取决于他们的姓名是否与 Pi 账户相符，以及是否被列入政府制裁名单。因此， KYC 有助于确保网络的真正人性化，并遵守反洗钱和反恐怖主义条例。 正如网络创立时所传达的，为确保真人性，严禁伪圆周率账号和照本宣科式挖掘。这些帐户将被禁用，并将无法迁移到 Mainnet 。在过去的三年中，已经实施了多种技术机制来识别机器人和假账户。对于被 Pi 的算法识别为极有可能造假的账户，权重就在这些账户上，以证明不是这样的。这些被识别出的虚假账户要么将被禁用，要么将经历更为严格的审查和上诉过程。的分配KYC槽将优先考虑的帐户有很大的可能性是真正的人持有人。 只有经过身份验证的账户才允许转入 Mainnet ，只有属于身份验证账户的 Pi 余额才能转入 Main net 余额。当先驱者及其推荐团队和安全圈成员通过KYC决定先锋是否、何时以及在多大程度上可以转移他们的余额。下面是一个假设的示例，以说明KYC对先驱者的核查将影响他们向主网迁移的平衡。 为了简单起见，我们将 Pi 天平的不同概念定义如下：
假设个人 A 是 Pi 账户的所有者，他想要转移他们的移动余额。先锋 A 只有在身份验证后，即通过KYC.假设这个人在其推荐团队中有 B 、 C 、 D 和 E 个人，在其安全圈中有 D 、 E 、 F 和 G 个人。到目前为止，只有 A 、 B 、 D 、 F 四个人完成了他们的KYC核查 在此示例设置中：
在这里， A 的可转让余额是以下三个组成部分的总和：
As more of Pioneer A’s referral team and security circle members (i.e., C, E, and G) pass KYC, more portions of A’s Mobile Balance will become Transferable Balance—ready for A to migrate to the Mainnet, and ultimately become A’s Mainnet Balance. During the Enclosed Mainnet period, any Mobile Balance that has not become Transferable Balance will remain in the Mobile mining app until the associated Pioneers in the referral team and security circles pass KYC and the corresponding amount becomes transferable to Mainnet. In the case of the above example of Pioneer A, the balance contribution by C, E, and G will remain as Mobile Balance for A in the mining app waiting for them to pass KYC in order for such balance to become transferable. If such associated accounts never pass KYC, the balance attributed to these non-KYC’ed accounts will expire at a certain date which will have allowed enough time for the whole network to KYC. The unclaimed balances due to lack of KYC will be discarded by not being transferred to the Mainnet at all. Restrictions in the Enclosed Network虽然在 Pi 网络中允许 Pi 应用程序与先锋和先锋对先锋事务之间的事务，但封闭网络将有如下限制。现阶段的这些限制有助于加强网络的封闭性：
封闭式网络将支持PI生态系统的经济活动和增长。因此，先锋到先驱者交易是可以通过PI钱包，因为KYC‘ed先驱者将能够使用PI钱包处理PI。先驱者还可以在PI浏览器上使用PI应用程序，后者可以通过PI应用程序SDK和PI BlockChain API访问Mainnet。在封闭的网络期间，PI浏览器上的应用程序只能使用防火墙白化的PI块链API与Mainnet交互。 将允许先锋到先驱者、先锋到应用程序和应用程序到先驱者交易的下列用途：
禁止下列用途：
We will enforce the above restrictions by adding a firewall to the Mainnet and by exclusively running the Mainnet Nodes for this interim period. Community Nodes will continue to run on the Testnet in the Enclosed Network period. We will continue to implement interface and other changes to the Nodes in preparation for the Open Network period where the Community Nodes will be able to run on the Mainnet. The restrictions of the Network to keep it enclosed will be relaxed as it reaches the next period—Open Network. The Open Network Period取决于封闭网络经济的成熟度和网络的进步KYC,这个时期可能从圆周率日（ 2022 年 3 月 14 日）开始，初二（ 2022 年 6 月 28 日），或以后。开放网络时期意味着封闭网络时期的防火墙将被移除，允许任何外部连接，例如，到其他网络、钱包和任何想要连接到 Pi Mainnet 的人。API 调用将不会被防火墙屏蔽，并且 Pioneers 将能够运行自己的 Pi 节点和 API 服务。先驱者将与其他区块链建立连接。社区节点也可以运行 Mainnet 。 以下是原文： Below is the new draft of the Roadmap chapter of our whitepaper. It reviews the first two phases of the network (Beta and Testnet), and introduces the Mainnet phase in more detail. Your feedback is welcome before we update the official whitepaper on our website when Open Network begins. Keep in mind that we are also working on new drafts of other whitepaper chapters and will release them soon, which will potentially further clarify questions you may have now. RoadmapPi Network is unique in our technological and ecosystem design as well as the significance of our community input in development. This uniqueness is best served by a thoughtful and iterative approach that allows for community feedback, testing of products, features, and user experience, and phases defined by milestones. There are three main phases to our development: (1) Beta, (2) Testnet, and (3) Mainnet. Phase 1: BetaIn December 2018, we publicly launched our mobile app on the iOS App store as an alpha prototype that onboarded the initial Pioneers. On Pi Day, March 14, 2019, the original Pi whitepaper was published, marking the official launch of the Pi Network. At this stage, our app allowed Pioneers to mine Pi by contributing to the growth and security of the future Pi blockchain. As the eventual goal was to launch the Mainnet and build an ecosystem around the Pi platform, the Pi app running on the centralized Pi server enabled mobile phone users (Pioneers) to contribute their security circles that, in aggregate, built the trust graph required by the consensus algorithm of the Pi Blockchain, and in return, the Pioneers received mining rewards. Furthermore, the centralized phase allowed the network to grow, the community to form, and the Pi token to be accessible and widely distributed. This phase also allowed for the iteration of many technical features and Pioneer experience by leveraging community input throughout the development process. The following major accomplishments were made during the Beta phase:
Phase 2: TestnetThis phase started on March 14, 2020, marking another critical preparation to the transition to a decentralized blockchain—a live Testnet with distributed Nodes from all over the world. Pi Network’s Node software enabled individual computers to support running the Pi Testnet using Test-Pi coin. Test-Pi was available only for the purpose of testing and has no relation to Pioneers’ account balances on the Pi app. The Pi Testnet has reached over 10,000 fully functional community Nodes and over 100,000 daily active Nodes on the waiting list, and as explained in a later section, will continue to exist for testing purposes in the Mainnet phase. Pi Testnet allows for the testing of connectivity, performance, security, and scalability of the blockchain, and allows Pi apps developers to develop the Pi apps before they can deploy their app on the Mainnet. During the Testnet phase, 3 major strategies were adopted: (1) decentralization through Testnet Nodes, (2) growth through the main Pi app for mobile mining, and (3) utility creation through the Pi apps platform on the Pi Browser. The Testnet ran in parallel with the Pi mobile mining app from Phase 1 and enabled decentralized community Nodes to get online and ready for the Mainnet. Specifically, the Testnet Nodes helped with the assessment of the blockchain’s performance, security, and scalability. It also helped Pi App developers test their apps against the Pi Blockchain. At the same time, the Pi mobile mining app continued to onboard millions of Pioneers, building the community and contributing to the security of the blockchain. The Pi Browser, along with the Pi SDK, enabled the community to create utilities and develop the Pi ecosystem. The following major accomplishments were made during the Testnet phase:
Phase 3: MainnetIn December 2021, the Mainnet of the Pi blockchain will go live. The migration of Pioneer balances from their phone account to the Mainnet starts during this period. KYC authentication of a Pioneer precedes their balance migration to the Mainnet. In order to allow for sufficient time for millions of Pioneers to successfully complete their KYC verification, create utilities in the Pi ecosystem, and continue to iterate on our technology and ecosystem design, the Mainnet will have two periods:
The Enclosed Network PeriodThis period will begin in December 2021. The Enclosed Network period means that the Mainnet is live but with a firewall that prevents any unwanted external connectivity. Pioneers will be able to take time to KYC and migrate their Pi to the live Mainnet blockchain. Any balance migrated to the Mainnet can be used, by the choice of the Pioneer, to purchase goods and services in Pi apps, transfer to other Pioneers, or get locked up for a duration of time for a higher mining rate. KYC’ed Pioneers will be able to use their Pi on the Mainnet freely in an enclosed environment within Pi Network. However, this period will not allow connectivity between the Pi blockchain and other blockchains. Advantages of the Two-Period Approach to MainnetThere are multiple advantages to having an intermediate enclosed period to ramp up to the fully open Mainnet. This approach allows time for:
The Enclosed Network period allows time for millions of Pioneers to KYC and migrate their Pi to the Mainnet. Only a small fraction of Pioneers have been able to complete their KYC around the launch of the Mainnet. Over the coming months, we will continue to roll out the KYC solution to more Pioneers and help them complete their KYC. If we moved directly from Testnet to Open Network, this would mean that the Pioneers who were able to KYC before others would have Pi available for use outside of the Pi platform while the Pioneers still waiting to complete their KYC would not yet have this privilege. The speed at which Pioneers all over the world are able to complete their KYC will depend on the speed at which each local community provides the KYC validator crowd work force as well as the speed at which individual Pioneers participate in the KYC. Having the Enclosed Network period gives time for millions of Pioneers to complete their KYC and transfer their Pi to the Mainnet. This way, all the Pioneers who are willing and able to complete their KYC in a reasonable period of time get to use their Pi outside of the Pi platform at once. Given that external connectivity between the Pi Blockchain and other blockchains or systems is not allowed during the Enclosed Network period, this further helps Pioneers focus on transitioning into Mainnet without any influences external to the Pi Blockchain. This period will also help the community focus on creating utilities and bootstrapping the ecosystem without any external distractions. Consistent with the vision of the Pi network to enable a utility-based ecosystem, this allows apps to deploy on Mainnet and create utilities for Pioneers. Pi apps will be able to switch from Testnet to Mainnet—to production mode for real Pi transactions. At this time, KYC’ed Pioneers will be able to spend their Pi on Pi apps, boosting utilities creation and bootstrapping the Pi ecosystem before the Open Network. This gradual and deliberate ramp to Open Network will help the apps, as well as the Pi Network, to uncover and resolve any glitches in the market and the technology. Thus, the Enclosed Network period is in line with Pi’s vision of a utility-based ecosystem and its iterative philosophy. Moreover, the Enclosed Network will allow the Mainnet to run with production data and real Pi, which differs from Testnet. Data gathered during the Enclosed Network will help calibrate and tweak any configurations and formulae, if necessary, to ensure a stable and successful Open Network. KYC Verification and Mainnet Balance Transfer“Know Your Customer/Client” (KYC) is a process that verifies identification to distinguish genuine accounts from fake ones. The vision of Pi Network is to build an inclusive and the most widely distributed token and ecosystem for all Pioneers. The mining mechanism of Pi Network is social network-based, and the mining rate has halved 5 times so far as the social network size grew to over 1K, 10K, 100K, 1M, and 10M engaged members. Therefore, Pi has a strict policy of one account per person. This requires a high degree of accuracy to establish that members in the network are genuine human beings, preventing individuals from being able to unfairly hoard Pi by creating fake accounts. Pioneers’ KYC results will depend on not only identity verification, but also their name matching with the Pi account and screening against government sanction list. KYC, thus, helps ensure the true humanness of the network and compliance with the Anti-Money Laundering (AML) and anti-terrorism regulations. As communicated at the founding of the network, to ensure true humanness, fake Pi accounts and scripted mining are strictly prohibited. These accounts will be disabled, and will not be able to migrate to Mainnet. Over the past three years, multiple technical mechanisms have been implemented to identify bots and fake accounts. For the accounts identified as highly likely to be fake by Pi’s algorithm, the weight is on these accounts to prove otherwise. These identified fake accounts will either be disabled or go through a much more rigorous review and appeal process. The allocation of KYC slots will be prioritized for accounts with a high likelihood of being true human holders. Only the accounts with verified identities will be allowed to transition to Mainnet, and only the Pi balances attributable to identity-verified accounts will be allowed to transfer to the Mainnet balance. When a Pioneer and their referral team and security circle members pass the KYC determines if and when, and to what extent, a Pioneer can transfer their balances. Below is a hypothetical example to illustrate how the KYC verification of Pioneers affects their balances in migration to the Mainnet. For simplicity, we define different concepts of Pi balances as follows:
Suppose individual A is the owner of a Pi account who wants to transfer their Mobile Balance. Pioneer A will only be allowed to transfer any of the Mobile Balance to the Mainnet when their identity is verified, i.e., when they pass the KYC. Let’s say this individual has Individuals B, C, D, and E on their referral team and Individuals D, E, F, and G in their security circle. So far, only individuals A, B, D, and F have completed their KYC verification. In this example setup:
Here, A’s Transferable Balance is the sum of the following three components:
As more of Pioneer A’s referral team and security circle members (i.e., C, E, and G) pass KYC, more portions of A’s Mobile Balance will become Transferable Balance—ready for A to migrate to the Mainnet, and ultimately become A’s Mainnet Balance. During the Enclosed Mainnet period, any Mobile Balance that has not become Transferable Balance will remain in the Mobile mining app until the associated Pioneers in the referral team and security circles pass KYC and the corresponding amount becomes transferable to Mainnet. In the case of the above example of Pioneer A, the balance contribution by C, E, and G will remain as Mobile Balance for A in the mining app waiting for them to pass KYC in order for such balance to become transferable. If such associated accounts never pass KYC, the balance attributed to these non-KYC’ed accounts will expire at a certain date which will have allowed enough time for the whole network to KYC. The unclaimed balances due to lack of KYC will be discarded by not being transferred to the Mainnet at all. Restrictions in the Enclosed NetworkWhile transactions between Pi apps and Pioneers and Pioneer-to-Pioneer transactions are allowed within Pi Network, the Enclosed Network will have in place the restrictions as listed below. These restrictions at this stage help enforce the enclosed nature of the network:
The Enclosed Network will support the economic activities and growth of the Pi ecosystem. Thus, Pioneer-to-Pioneer transactions are possible through the Pi Wallet as KYC’ed Pioneers will be able to use the Pi Wallet to transact in Pi. Pioneers can also spend Pi in Pi apps on the Pi Browser, which can access the Mainnet through the Pi Apps SDK and the Pi Blockchain API. During the Enclosed Network period, an app on the Pi Browser can only use the Pi blockchain APIs whitelisted by the firewall to interact with the Mainnet. The following uses of Pioneer-to-Pioneer, Pioneer-to-App, and App-to-Pioneer transactions will be allowed:
The following uses will be prohibited:
