Roadmap

Pi 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: Beta

In 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:

• The Pi Network mobile app was listed and accessible through the iOS App Store and Google Playstore.
• Pi Network grew from 0 to over 3.5 million engaged Pioneers.
• The Pi Network community actively engaged with the project through the app home screen interactions and chat app.
• Pi Network reached 233 countries and regions around the world.

Phase 2: Testnet

This 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:

• Many versions of the Node software were released.
• The Pi Platform was released along with key ingredients of our ecosystem infrastructure: Wallet, Browser, Brainstorm and developer tools.
• Pilot version of the KYC app was introduced on the Pi Browser.
• The project ran its first ever worldwide online Hackathon with thousands of participants from within the Pioneer Community.
• Pi Network grew to over 30 million engaged Pioneers, and from 0 to over 10,000 fully functional community Nodes and over 100,000 daily active Nodes on the waiting list.
• Pi Network reached almost all countries and regions in the world.

Phase 3: Mainnet

In 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:

1. at first, firewalled Mainnet (i.e., the Enclosed Network),
2. and then, open Mainnet (i.e., the Open Network).

The Enclosed Network Period

This 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 Mainnet

There are multiple advantages to having an intermediate enclosed period to ramp up to the fully open Mainnet. This approach allows time for:

• millions of Pioneers worldwide to pass KYC,
• building and deploying more Pi Apps and allowing more utilities to be created and used,
• transitioning Pi Apps deployed on the Testnet to the Mainnet, and
• iterating on any modifications and adjustments to the Mainnet and the ecosystem before the Open Network.

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:

• Mobile Balance: The Pi balance currently shown in a Pioneer’s account in the Pi mobile app
• Transferable Balance: The balance that has been allowed to be transferred to the Mainnet because the Pioneer and their specific associated individuals in the referral teams and security circles have passed KYC
• Mainnet balance: The balance that has been migrated and transferred by the Pioneer to the Mainnet

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:

• A is a mining Pioneer who has passed KYC.
• B, C, D, E are in the Referral Team of A.
• D, E, F, G are in the Security Circle of A.
• A, B, D, and F have passed KYC.

Here, A’s Transferable Balance is the sum of the following three components:

• Pioneer Rewards: Pi mined based on A’s Pioneer status across all mining sessions
• Contributor Rewards: D and F’s contribution to A's mining rate as Contributors in all mining sessions
• Ambassador Rewards: Mining bonuses from all mining sessions when B and D as referral team members mined during the same session as A mined

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

While 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:

• There will be no connectivity between Pi and other blockchains or crypto exchanges.
• Mainnet can only be accessed through the Pi Wallet and Pi apps on the Pi Browser.
• The Mainnet blockchain will be accessible to any computer on the internet but only through a firewall to enforce the above rules.
• There will only be Core Team Nodes on the Mainnet to ensure that the firewall is in place at all times.

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:

• Exchange of Pi for goods and services through Pi Apps
• Transfer of Pi between Pioneers for goods and services

The following uses will be prohibited:

• Exchange of Pi for fiat currency
• Exchange of Pi for other cryptocurrencies
• Transfer for Pi for a future promise of fiat or other cryptocurrencies

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

Depending on the maturity of the Enclosed Network economy and the progress of the KYC, this period may begin on Pi Day (March 14, 2022), Pi2 Day (June 28, 2022), or later. The Open Network period means that the firewall in the Enclosed Network period will be removed, allowing any external connectivity, e.g., to other networks, wallets, and anyone who wants to connect to Pi Mainnet. API calls will not be firewalled, and Pioneers will be able to run their own Pi Nodes and API services. Pioneers will have connectivity with other blockchains. Community Nodes can also run the Mainnet.

以下是我们白皮书路线图章节的新草案。它回顾了网络的前两个阶段（Beta和Testnet），并更详细地介绍了主网阶段。欢迎您在开放网络开始时更新我们网站上的官方白皮书之前提供反馈。请记住，我们还在撰写其他白皮书章节的新草案，并将很快发布，这可能会进一步澄清您现在可能遇到的问题。

路线图

Pi Network在我们的技术和生态系统设计以及社区参与开发的重要性方面是独一无二的。这种独特性最好通过深思熟虑的迭代方法实现，该方法允许社区反馈，产品，功能和用户体验的测试以及由里程碑定义的阶段。我们的开发有三个主要阶段：（1）Beta，（2）测试网和（3）主网。

第 1 阶段：测试版

2018 年 12 月，我们在 iOS App Store 上公开推出了我们的移动应用程序，作为 Alpha 原型，加入了最初的 Pioneers。2019 年 3 月 14 日 Pi 日，Pi 白皮书发布，标志着 Pi 网络正式发布。在这个阶段，我们的应用程序允许Pioneers通过为未来Pi区块链的增长和安全性做出贡献来挖掘Pi。由于最终目标是启动主网并围绕Pi平台构建生态系统，因此在集中式Pi服务器上运行的Pi应用程序使手机用户（Pioneers）能够贡献他们的安全圈，这些安全圈总体上构建了Pi区块链共识算法所需的信任图，作为回报，Pioneers获得了挖矿奖励。此外，集中式阶段允许网络增长，社区形成，Pi令牌可访问和广泛分发。此阶段还允许在整个开发过程中利用社区意见，对许多技术功能和 Pioneer 体验进行迭代。

在测试阶段取得了以下主要成就：

Pi Network移动应用程序已列出，可通过iOS App Store和Google Playstore访问。

Pi Network从0增长到超过350万参与先锋。

Pi Network社区通过应用程序主屏幕交互和聊天应用程序积极参与该项目。

Pi网络覆盖全球233个国家和地区。

第 2 阶段：测试网

此阶段于2020年3月14日开始，标志着向分散式区块链过渡的另一个关键准备 - 一个具有来自世界各地的分布式节点的实时测试网。Pi Network的Node软件使单个计算机能够支持使用Test-Pi硬币运行Pi测试网。Test-Pi仅用于测试目的，与Pi应用程序上的Pioneers帐户余额无关。Pi Testnet已经达到了超过10，000个功能齐全的社区节点和等待列表中的超过100，000个每日活动节点，并且如后面的部分所述，将继续存在以用于主网阶段的测试目的。

Pi Testnet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应用程序开发人员在主网上部署其应用程序之前开发Pi应用程序。在Testnet阶段，采用了3个主要策略：（1）通过Testnet节点进行去中心化，（2）通过用于移动挖掘的主要Pi应用程序实现增长，以及（3）通过Pi浏览器上的Pi应用程序平台创建实用程序。测试网与第1阶段的Pi移动采矿应用程序并行运行，并使分散的社区节点能够上线并为主网做好准备。具体来说，测试网节点有助于评估区块链的性能、安全性和可扩展性。它还帮助Pi App开发人员针对Pi区块链测试了他们的应用程序。与此同时，Pi移动挖矿应用继续载入数百万先锋，建立社区，为区块链的安全性做出贡献。Pi 浏览器以及 Pi SDK 使社区能够创建实用程序并开发 Pi 生态系统。

在测试网阶段取得了以下主要成就：

发布了许多版本的Node软件。

Pi平台与我们生态系统基础设施的关键组成部分一起发布：钱包，浏览器，头脑风暴和开发人员工具。

KYC应用程序的试点版本在Pi浏览器上推出。

该项目运行了有史以来第一次全球在线黑客马拉松，来自先锋社区内的数千名参与者。

Pi Network发展到超过3000万参与的Pioneers，从0到超过10，000个功能齐全的社区节点和超过100，000个每日活跃节点在等待名单上。

Pi网络几乎覆盖了世界上所有的国家和地区。

阶段 3：主网

2021年12月，Pi区块链的主网将上线。在此期间，Pioneer余额从其手机帐户迁移到主网开始。先锋的KYC身份验证在其余额迁移到主网之前。为了让数百万先锋有足够的时间成功完成他们的KYC验证，在Pi生态系统中创建实用程序，并继续迭代我们的技术和生态系统设计，主网将有两个阶段：

首先，防火墙主网（即封闭网络），

然后，打开主网（即开放网络）。

封闭的网络期间

这段时间将于2021年12月开始。封闭网络期间意味着主网处于活动状态，但具有防火墙，可防止任何不需要的外部连接。先驱者将能够花时间进行KYC并将其Pi迁移到实时主网区块链。根据先锋的选择，迁移到主网的任何余额都可用于在Pi应用程序中购买商品和服务，转移到其他先锋，或者被锁定一段时间以获得更高的采矿率。KYC'ed Pioneers将能够在Pi网络的封闭环境中在主网上自由使用他们的Pi。但是，此期限将不允许 Pi 区块链与其他区块链之间的连接。

主网双周期方法的优点

拥有一个中间封闭的周期以提升到完全开放的主网有很多优点。这种方法为以下方面留出了时间：

全球数以百万计的先驱者通过KYC，

构建和部署更多 Pi 应用，并允许创建和使用更多实用程序，

将部署在测试网上的 Pi 应用转换为主网，以及

迭代开放网络之前对主网和生态系统的任何修改和调整。

封闭式网络期为数百万先驱者提供了时间进行KYC并将其Pi迁移到主网。只有一小部分先驱者能够在主网启动前后完成他们的KYC。在接下来的几个月里，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KYC。如果我们直接从Testnet转移到Open Network，这意味着能够在其他人之前进行KYC的先驱者将拥有Pi，可以在Pi平台之外使用，而仍在等待完成KYC的先驱者将还没有此特权。世界各地的先驱者能够完成KYC的速度将取决于每个当地社区提供KYC验证者人群劳动力的速度以及个人先驱者参与的速度。n KYC.

拥有封闭式网络期为数百万先驱者提供了时间来完成他们的KYC并将其Pi传输到主网。这样，所有愿意并且能够在合理的时间内完成KYC的先驱者都可以立即在Pi平台之外使用他们的Pi。鉴于在封闭网络期间不允许Pi区块链与其他区块链或系统之间的外部连接，这进一步帮助Pi Pioneers专注于过渡到主网，而不会受到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，而没有任何外部干扰。与Pi网络的愿景一致，即实现基于实用程序的生态系统，这允许应用程序部署在主网上并为Pioneers创建实用程序。Pi 应用程序将能够从 Testnet 切换到主网，从而切换到生产模式以进行真正的 Pi 事务。目前，KYC'ed Pioneers将能够将他们的Pi花在Pi应用程序上，从而促进实用程序的创建，并在开放网络之前引导Pi生态系统。这种逐步和深思熟虑的开放网络将帮助应用程序以及Pi网络发现和解决市场和技术中的任何故障。因此，封闭网络时期符合Pi对基于效用的生态系统的愿景及其迭代理念。

此外，封闭式网络将允许主网使用生产数据和真实Pi运行，这与测试网不同。如有必要，在封闭网络期间收集的数据将有助于校准和调整任何配置和公式，以确保稳定和成功的开放网络。

KYC验证和主网余额转移

"了解您的客户/客户"（KYC）是一个验证身份以区分真实帐户和虚假帐户的过程。Pi Network的愿景是为所有先驱者建立一个包容且分布最广泛的令牌和生态系统。Pi Network的挖矿机制是基于社交网络的，挖矿率已经减半了5倍，到目前为止，社交网络规模增长到超过1K，10K，100K，1M和10M参与会员。因此，Pi 有一个严格的政策，即每人一个帐户。这需要高度的准确性来确定网络中的成员是真实的人，防止个人能够通过创建虚假帐户来不公平地囤积Pi。Pioneers的KYC结果不仅取决于身份验证，还取决于他们的名字与Pi帐户的匹配以及政府制裁名单的筛选。因此，KYC有助于确保网络的真正人性化并遵守反洗钱（AML）和反恐法规。

正如网络成立时所传达的那样，为确保真实的人性，严禁伪造Pi帐户和脚本化挖矿。这些帐户将被禁用，并且将无法迁移到主网。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虚假帐户。对于被Pi算法确定为极有可能是假的帐户，权重在于这些帐户以证明并非如此。这些已识别的虚假帐户将被禁用或经过更严格的审查和上诉程序。KYC插槽的分配将优先用于极有可能成为真正人类持有者的帐户。

只有具有已验证身份的账户才能过渡到主网，并且只有归因于身份验证账户的Pi余额才能转移到主网余额。当先锋及其推荐团队和安全圈成员通过时，KYC确定先锋是否可以，何时以及在多大程度上转移他们的余额。下面是一个假设的例子，以说明先锋的KYC验证如何影响他们在迁移到主网时的余额。

为简单起见，我们定义了 Pi 天平的不同概念，如下所示：

移动余额：Pi 余额当前显示在 Pi 移动应用程序中先锋帐户中的 Pi 余额

可转移余额：由于先锋及其在推荐团队和安全圈中的特定相关个人已通过KYC而允许转移到主网的余额

主网余额：先锋号迁移并转移到主网的余额

假设个人 A 是想要转移其移动余额的 Pi 帐户的所有者。先锋A只有在验证其身份时（即当他们通过KYC时）才能将任何移动余额转移到主网。假设此人在其推荐团队中有个人 B、C、D 和 E，在他们的安全圈中有个人 D、E、F 和 G。到目前为止，只有个人A，B，D和F完成了KYC验证。

在此示例设置中：

A是已经通过KYC的采矿先驱。

B，C，D，E在A的推荐团队中。

D，E，F，G都在A的安全圈中。

A，B，D和F已通过KYC。

此处，A 的可转移余额是以下三个组成部分的总和：

先锋奖励：Pi 根据 A 在所有采矿会话中的先锋状态进行开采

贡献者奖励：D 和 F 作为所有挖矿会话中的投稿人对 A 挖矿率的贡献

大使奖励：当 B 和 D 作为推荐团队成员在与 A 开采的同一会话中开采时，从所有挖矿会话中挖掘奖金

随着越来越多的先锋A的推荐团队和安全圈成员（即C，E和G）通过KYC，A的移动余额的更多部分将成为可转移余额 - 准备让A迁移到主网，并最终成为A的主网余额。

在封闭式主网期间，任何尚未成为可转移余额的移动余额将保留在移动采矿应用程序中，直到推荐团队和安全圈中的相关先锋通过KYC并且相应的金额可转移到主网。在上述先锋A的例子中，C，E和G的余额贡献将保留为采矿应用程序中A的移动余额，等待它们通过KYC，以便该余额可转移。如果此类关联帐户从未通过KYC，则归因于这些非KYC帐户的余额将在特定日期到期，这将为整个网络留出足够的时间进行KYC。由于缺乏KYC而无法认领的余额将通过根本不转移到主网而被丢弃。

封闭网络中的限制

虽然 Pi 应用程序与 Pioneers 之间的交易以及 Pioneer-to-Pioneer 交易在 Pi Network 中是允许的，但封闭式网络将具有下面列出的限制。此阶段的这些限制有助于强制实施网络的封闭性质：

Pi与其他区块链或加密交换之间将没有连接。

主网只能通过 Pi 浏览器上的 Pi 钱包和 Pi 应用程序访问。

互联网上的任何计算机都可以访问主网区块链，但只能通过防火墙来执行上述规则。

主网上将只有核心团队节点，以确保防火墙始终就位。

封闭式网络将支持Pi生态系统的经济活动和增长。因此，先锋对先锋的交易可以通过Pi钱包进行，因为KYC的先锋将能够使用Pi钱包在Pi中进行交易。先驱者还可以在Pi浏览器上的Pi应用程序中花费Pi，该浏览器可以通过Pi Apps SDK和Pi Blockchain API访问主网。在封闭网络期间，Pi 浏览器上的应用只能使用防火墙列入白名单的 Pi 区块链 API 与主网进行交互。

将允许以下使用先锋对先驱者、先驱者到应用程序和应用程序到先驱者交易：

通过 Pi 应用程序交换 Pi 的商品和服务

Pi在先驱者之间转移商品和服务

禁止以下用途：

将 Pi 兑换成法定货币

将 Pi 交换为其他加密货币

为Pi转移，以获得未来对法定货币或其他加密货币的承诺

我们将通过向主网添加防火墙并在此过渡期间专门运行主网节点来强制执行上述限制。社区节点将在封闭的网络期间继续在测试网上运行。我们将继续对节点实施接口和其他更改，为开放网络期间做准备，社区节点将能够在主网上运行。网络为保持封闭而进行的限制将在进入下一个时段（开放网络）时放宽。

开放网络期

根据封闭网络经济的成熟度和KYC的进展，这段时间可能从Pi日（2022年3月14日），Pi2日（2022年6月28日）或更晚开始。开放网络期间意味着封闭网络期间的防火墙将被移除，允许任何外部连接，例如，与其他网络，钱包以及想要连接到Pi Mainnet的任何人。API调用将不受防火墙保护，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主网。
