重要通知！Pi币主网上线！最新白皮书发布以及注意事项

Pi Mainnet is live today, initiating the Enclosed Network period of Mainnet phase. We are also releasing two new sections of the Pi white paper that explain how mining and supply will work in Mainnet. A preview of a new mining simulation is released in the app for your calibration and will take effect later. Until then, existing mining continues. Read more above. Mainnet can be viewed in the Pi Blockexplorer, and your Pi wallet can now show both Testnet and Mainnet balances.

Pi Mainnet 今天上线，开启了 Mainnet 阶段的封闭式网络时代。我们还将发布 PI白皮书的两个新部分，解释 Mainnet 中的采矿和供应如何工作。新的采矿模拟的预览将在应用程序中发布，供您校准，并将在稍后生效。在此之前，现有的采矿仍在继续。请阅读上面的更多内容。可以在 PI BlockExplorer 中查看 Mainnet，并且您的 PI 钱包现在可以同时显示 Testnet 和 Mainnet 余额。

Mainnet Launch 主网发布
Pi Mainnet is now live, initiating the Enclosed Network period of Mainnet phase where the Mainnet blockchain is firewalled to prohibit external connectivity but allows peer-to-peer and peer-to-app transfers within the enclosed network. Mainnet can be viewed in the Pi Blockexplorer. Pi wallet can now show both Testnet and Mainnet balances, although everyone’s balance on Mainnet is 0 right now. As more Pioneers pass KYC, they will be able to transfer their balance to the Mainnet. The KYC solution is coming soon to start verifying Pioneers’ identity and onboarding identity validators.

Pi Mainnet 现已启用，启动了 Mainnet 阶段的封闭式网络期，在封闭式网络阶段，Mainnet 区块链被防火墙保护以禁止外部连接，但允许在封闭式网络内进行对等和对等传输。可以在 PI Block Explorer 中查看 Mainnet。PI 钱包现在可以同时显示 Testnet 和 Mainnet 余额，尽管每个人在 Mainnet 上的余额现在都是 0。随着更多的先锋队员通过 KYC，他们将能够将他们的余额转移到 Mainnet。KYC 解决方案即将推出，将开始验证先锋的身份并让身份验证员登机。

Note that Pi Network is NOT running an ICO or any type of crowdfunding sales of Pi. Thus, any party impersonating Pi Network or its founders to conduct a sale or listing is illegal and fake. Any sales of Pi towards Pioneers are unauthorized and have no affiliation with the Pi Core Team. Pioneers should beware of any scams and not participate. Pi can be mined freely by contributing to the ecosystem through our mobile app. Further, any mined Pi can only be claimed from inside the official Pi App through the Mainnet dashboard and then transferred into your Pi wallet. Any website asking Pioneers to claim Pi by other means is fake.

Below is the new draft of the Pi supply and mining sections of our whitepaper. Mining will continue in the Mainnet phase but with a mining rate dynamically adjusted within limited supply. For more details, read the new whitepaper sections that review how supply and mining worked before Mainnet and describe how and why they will change at Mainnet. We will also keep the previously released Roadmap chapter at the bottom for reference. Your feedback is welcome before we update the official whitepaper on our website when Open Network begins.

请注意，Pi Network 不进行 ICO 或任何类型的 PI 众筹销售。因此，任何一方冒充 Pi Network 或其创始人进行出售或上市都是非法和虚假的。任何 PI 向先锋队的销售都是未经授权的，并且与 PI 核心团队没有任何关联。开拓者应该提防任何骗局，不要参与。PI 可以通过我们的移动应用程序为生态系统做出贡献，从而自由开采。此外，任何开采的 PI 只能通过 Mainnet Dashboard 从官方 PI App 内部认领，然后转移到您的 PI 钱包中。任何要求先锋队以其他方式声称 PI 的网站都是假的。

Today we are also releasing a preview of the new mining interface for you to view the new simulated Mainnet mining mechanism in a hypothetical setting and to help you calibrate your lockup setting. The new mining mechanism will not yet go into effect until more people pass KYC and migrate to the Mainnet. Before that, all Pioneers can continue mining on the pre-Mainnet mechanism just like before. Once the simulations and calibrations are done and enough Pioneers have migrated into Mainnet, the new Mainnet mining mechanism will take effect and be announced on the home screen.

今天，我们还发布了新挖掘界面的预览，让您在假设的设置下查看新的模拟 Mainnet 挖掘机制，并帮助您校准锁定设置。在更多的人通过 KYC 并迁移到 Mainnet 之前，新的挖掘机制还不会生效。在此之前，所有先锋都可以像以前一样继续在 Pre-Mainnet 机制上挖掘。一旦模拟和校准完成，足够多的先驱者迁移到 Mainnet，新的 Mainnet 挖掘机制将生效并在主屏幕上公布。

Token Model and Mining 令牌模型与挖掘
A well thought-out, sound token design is critical to the success of a cryptocurrency network. It has the potential to create incentives to bootstrap network formation and growth, build a utilities-driven ecosystem, and thereby support the cryptocurrency underpinning such a system. What a network incentivizes says a lot about what a network needs—for example, network growth or fundamentals-driven utility creation, a mere store of value or a medium of exchange for the cryptonative ecosystem. This chapter covers the supply of Pi and how Pioneers can mine Pi in different phases of the network, and the underlying design rationale for different mining mechanisms including to build and grow the network and to incentivize utilities and demand. Note that Pi is a layer one cryptocurrency running on its own blockchain, which “token” here refers to.

一个深思熟虑、合理的令牌设计对于加密货币网络的成功至关重要。它有可能创造激励措施来引导网络的形成和增长，建立一个公用事业驱动的生态系统，从而支持支撑这样一个系统的加密货币。网络的激励在很大程度上说明了网络的需求-例如，网络增长或基本面驱动的公用事业创造，仅仅是价值储存或加密生态系统的交换媒介。本章介绍 PI 的供应以及 Pioneers 如何在网络的不同阶段挖掘 PI，以及不同挖掘机制的基本设计原理，包括构建和发展网络以及激励公用事业和需求。请注意，PI 是一种运行在自己的区块链上的第一层加密货币，这里的“令牌”指的是区块链。

Pi Supply
Pi Network’s vision is to build the world’s most inclusive peer-to-peer economy and online experience, fueled by Pi, the world’s most widely used cryptocurrency. To deliver on this vision, it is important to grow the network and make Pi widely accessible while maintaining the security of the blockchain and the scarcity of Pi. While these goals have always guided the token supply model and mining design, the key distinction is: the pre-Mainnet phases focused on driving network growth and widely distributing Pi and the Mainnet phase will focus on rewarding more diverse forms of Pioneer contributions while cementing the supply of Pi.

Pi Network 的愿景是在世界上使用最广泛的加密货币 Pi 的推动下，建立世界上最具包容性的 P2P 经济和在线体验。为了实现这一愿景，重要的是扩大网络，使 PI 能够广泛访问，同时保持区块链的安全性和 PI 的稀缺性。虽然这些目标一直指导令牌供应模型和挖掘设计，但主要区别在于：Pre-Mainnet 阶段专注于推动网络增长和广泛分布 PI，而 Mainnet 阶段将专注于奖励更多形式的先锋贡献，同时巩固 PI 供应。

Pre-Mainnet Supply 维护前供应
In the early stages, the focus of Pi Network was on growing and securing the network. Bootstrapping to build a critical mass of participants is paramount to any network and ecosystem. Driven by the vision to make Pi the world’s most widely used cryptocurrency, distributing Pi and making it accessible globally further added to the focus on growth. Pi’s consensus algorithm relies on a global trust graph, which is aggregated from the Security Circles of individual Pioneers. It was, therefore, critical to incentivize Pioneers to form individual Security Circles. This meant a supply of tokens available as mining rewards that was not explicitly capped before Mainnet.

在早期阶段，PI 网络的重点是发展和保护网络。建立足够数量的参与者的自举对于任何网络和生态系统都是至关重要的。在使 PI 成为世界上使用最广泛的加密货币的愿景的推动下，分发 PI 并使其在全球范围内可访问，进一步增加了对增长的关注。Pi 的共识算法依赖于一个全局信任图，该信任图是由各个先锋的安全圈聚合而成的。因此，激励先锋们组成单独的安全圈是至关重要的。这意味着在 Mainnet 之前，可用于采矿奖励的令牌的供应没有明确的上限。

At the same time, maintaining a certain scarcity of Pi was important. As explained under the Mining section, the network adopted a mining mechanism where the network mining rate halves every time the network size increases by 10 times, resulting in a series of halving events when it reaches various milestones of engaged Pioneers. The next halving event based on this model would be when the network reaches 100 million engaged Pioneers. Currently, we are over 30 million engaged Pioneers. The network also retained an option to stop all mining altogether in the event that the network reached a certain size, which was, however, yet to be determined. The option to cap the supply of Pi was not exercised before Mainnet, therefore leaving the total supply undefined.

同时，保持一定的 PI 稀缺性也很重要。正如挖掘部分所解释的那样，网络采用了挖掘机制，网络规模每增加 10 倍，网络挖掘率就会减半，当达到参与先锋的各种里程碑时，会导致一系列减半事件。基于这种模式的下一次减半活动将是当网络达到 1 亿名参与先锋时。目前，我们有 3000 多万名订婚先锋。该网络还保留了在网络达到一定规模(但尚未确定)时完全停止所有采矿的选择权。在 Mainnet 之前没有执行限制 PI 供应的选项，因此总供应量没有定义。

The pre-Mainnet supply model with a mining mechanism tailored to accessibility, growth and security has bootstrapped a community of over 30 million engaged Pioneers with millions of intertwined Security Circles. A simple, accessible means to mine Pi on a mobile phone helped distribute the tokens widely throughout the world, including among populations that have been left out of the crypto revolution because of a lack of capital, knowledge or technology. In doing so, the network avoided the extreme wealth concentration evident in Bitcoin and other cryptocurrencies, preparing itself to become a true peer-to-peer decentralized ecosystem with a large enough volume of participants and transactions for utility creation.

Mainnet 之前的供应模式具有专为可访问性、增长和安全量身定做的挖掘机制，已经引导了一个由 3000 多万名参与先锋和数百万个相互交织的安全圈子组成的社区。在手机上挖掘圆周率的一种简单、方便的方式帮助在世界各地广泛分发了这些令牌，包括在那些由于缺乏资金、知识或技术而被排除在密码革命之外的人群中。通过这样做，该网络避免了比特币和其他加密货币明显的极端财富集中，为成为一个真正的点对点去中心化生态系统做好了准备，有足够多的参与者和交易量来创造公用事业。

Mainnet Supply 主网供应
Supply fuels growth and incentivizes necessary contributions to the network to achieve an organically viable ecosystem. To that end, mining rewards will continue after Mainnet but will take diverse forms to incentivize different types of contributions, which will be explained in the Mining section below. In regard to supply, the undetermined supply due to the pre-Mainnet mining mechanism that optimizes for accessibility and growth of the network presents a few problems for the Mainnet phase, including unpredictability in planning, over-rewarding and under-rewarding different types of necessary contributions in the new phase, and challenges to scarcity. To address these issues, the network will shift from its pre-Mainnet supply model that is completely dependent on network behavior to the Mainnet supply model where there is a clear maximum supply.

供应推动增长，并激励对网络的必要贡献，以实现有机可行的生态系统。为此，在 Mainnet 之后，采矿奖励将继续，但将采取不同的形式来激励不同类型的贡献，这将在下面的采矿部分进行解释。在供应方面，由于前 Mainnet 开采机制优化了网络的可获得性和增长，导致供应不确定，这给 Mainnet 阶段带来了一些问题，包括规划的不可预测性、新阶段不同类型的必要捐款回报过高和回报过低，以及对稀缺性的挑战。为了解决这些问题，网络将从完全依赖网络行为的 Pre-Mainnet 供应模式转变为有明确最大供应的 Mainnet 供应模式。

The issue of unpredictability for planning in the pre-Mainnet supply model surfaced in Pi Network’s first COiNVENTION in September-October 2020 where the community panel and community submissions discussed whether mining should be halved or stopped at the network size of 10 million at the time. The diverse voices of community members presented the following dilemma for the network. If mining continued based on the ongoing (pre-Mainnet) mining mechanism, then it raised concerns for the supply due to uncertainty, and thus, the scarcity of Pi. However, if mining stopped, it would hurt the growth of the network and prevent new Pioneers joining the network as miners, thereby undermining the accessibility of Pi. Even though the network moved on from that decision and halved the mining rate at its 10 Million size, this dilemma still remains and needs to be resolved.

Pi Network 在 2020 年 9 月至 10 月的第一次会议上出现了前 Mainnet 供应模式计划的不可预测性问题，社区小组和社区提交的文件讨论了是应该将采矿减半还是应该在当时 1000 万的网络规模时停止采矿。社区成员的不同声音给该网络带来了以下两难境地。如果继续基于正在进行的(Pre-Mainnet)开采机制进行开采，那么由于不确定性而引起了对供应的担忧，因此，PI 的稀缺性也引起了人们的担忧。然而，如果停止采矿，将损害网络的增长，并阻止新的先锋作为矿工加入网络，从而破坏 PI 的可及性。尽管该网络放弃了这一决定，并将采矿率减半至 1000 万，但这一困境仍然存在，需要解决。

How the community can achieve continued growth and accessibility while addressing concerns about supply is one of the main factors considered in the design of the Mainnet token model. In addition, the undefined and unpredictable total supply makes it hard to have overall network token planning because the community as a collective and the ecosystem itself have needs to use some Pi for purposes that benefit the community and ecosystem as a whole, other than only mining rewards for individuals, as evidenced by almost every other blockchain network. Clear allocations for such collective community purposes need to be defined. Hence, given the current network size of over 30 million Pioneers and the expected volume of transactions and activities in the future, the Mainnet supply model has a clear maximum total supply of 100 billion Pi allowing incentivizations of continued growth and new contributions while removing the concerns about the unpredictability of the supply.

社区如何在解决供应问题的同时实现持续增长和可访问性，这是设计 Mainnet 令牌模型时考虑的主要因素之一。此外，不确定和不可预测的总供应量使得很难有整体的网络令牌规划，因为社区作为一个集体和生态系统本身需要使用一些 PI 来实现社区和生态系统作为一个整体受益的目的，而不是像几乎所有其他区块链网络所证明的那样，只为个人挖掘奖励。需要明确为此类集体社区目的分配资金。因此，考虑到目前先锋公司的网络规模超过 3000 万，以及未来预计的交易量和活动量，Mainnet Supply 模式明确的总供应量为 1000 亿 PI，允许激励持续增长和新的贡献，同时消除对供应不可预测性的担忧。

The supply distribution will honor the original distribution principle in the March 14, 2019 white paper—the Pi community has 80% and the Pi Core Team has 20% of the total circulating supply of Pi, regardless of how much circulating supply there is in the Pi Network at any given point in time. Thus, given a total max supply of 100 billion Pi, the community will eventually receive 80 billion Pi and the Core Team will eventually receive 20 billion Pi. The following pie chart depicts the overall distribution. The Core Team’s allocation gets unlocked at the same pace as the community progressively mines more and more Pi and may be subject to additional lockup through a self-imposed mandate. This means that if the community has a portion of its allocation in circulation (for example, 25%), only the proportional amount in Core Team’s allocation (in this example, 25%) can get unlocked at most.

货源分配将遵守 2019 年 3 月 14 日白皮书中的原始分配原则--PI 社区拥有 PI 总流通供应量的 80%，PI 核心团队拥有 20%的流通供应量，无论在任何给定时间点 PI 网络中有多少流通供应量。因此，假设总供应量为 1000 亿 PI，社区最终将获得 800 亿 PI，核心团队最终将获得 200 亿 PI。下面的饼图描述了总体分布情况。核心团队的分配随着社区逐渐挖掘越来越多的 PI 而以相同的速度被解锁，并可能通过自我强加的命令受到额外的锁定。这意味着，如果社区有一部分分配在流通中(例如，25%)，则最多只能解锁 Core Team 分配中的比例金额(在本例中为 25%)。

This distribution above shows that Pi Network does not have any allocation for ICO and is NOT running any type of crowdfunding sales of Pi. Thus, any impersonation of Pi Network or its founders to conduct a sale or listing is illegal, unauthorized and fake. These impersonators have no affiliation with Pi Core Team. Pioneers should beware of any scams and not participate. Pi can be mined freely by contributing to the ecosystem. Further, all mined Pi can only be claimed from inside the Pi App through the Mainnet dashboard and then transferred into your Pi wallet. Any website asking Pioneers to claim Pi in other means is fake.

上面的这一分布表明，Pi Network 没有任何 ICO 分配，也没有进行任何类型的 PI 众筹销售。因此，任何冒充 Pi Network 或其创始人进行销售或上市的行为都是非法、未经授权和虚假的。这些模仿者与 PI Core 团队没有任何关联。开拓者应该提防任何骗局，不要参与。PI 可以通过对生态系统的贡献而自由开采。此外，所有开采的 PI 只能通过 Mainnet 仪表板从 PI App 内部认领，然后转移到您的 PI 钱包中。任何要求先锋队以其他方式声称 PI 的网站都是假的。

The 80% of the community supply will be further divided into: 65% allocated for all past and future Pioneer mining rewards, 10% reserved for supporting community organization and ecosystem building that will eventually be managed by a Pi Foundation, a non-profit organization in the future, and 5% reserved for the liquidity pool to provide liquidity for Pioneers and developers in the Pi ecosystem. The following table depicts the community supply distribution:

社区供应的 80%将进一步划分为：65%分配给所有过去和未来的先锋采矿奖励，10%预留用于支持社区组织和生态系统建设，最终将由非营利性组织 Pi Foundation 管理，5%预留给流动资金池，为 Pi 生态系统中的 Pioneers 和开发商提供流动性。下表描述了社区用品的分布情况：

65 Billion Pi will be allocated for all mining rewards—both past and future mining. For past mining rewards, the rough sum of all Pi mined by all Pioneers so far (before Mainnet) is about 30 Billion Pi. However, after discarding Pi mined by fake accounts and depending on the speed and participation of KYC, the pre-Mainnet mined Pi at the beginning of the Open Network can be estimated to range from 10 to 20 Billion. The remaining amount in the 65 billion Pi supply for mining rewards will be distributed to Pioneers through the new Mainnet mining mechanism with conceptual yearly supply limits.

650 亿圆周率将分配给所有采矿奖励-包括过去和未来的采矿奖励。就过去的开采回报而言，到目前为止，所有先锋公司开采的所有 PI 的粗略总和(在 Mainnet 之前)约为 300 亿 PI。不过，剔除假账号挖出的 PI 后，根据 KYC 的速度和参与度，开网之初的 Pre-Mainnet 挖出的 PI 估计在 100 亿到 200 亿之间。用于采矿奖励的 650 亿圆周率供应中的剩余金额将通过新的 Mainnet 采矿机制分配给先锋公司，该机制具有概念性的年度供应限制。

Such yearly supply limits will be determined based on a declining formula. The yearly limit may be computed on a more granular basis such as by the day or by an even smaller time epoch dynamically, depending on factors such as the lockup ratio and the remaining supply of the network at the time. Such calculation of supply limits based on granular time epochs helps achieve a better and more smooth allocation curve through time. For the sake of simplicity here, let’s suppose that the time epoch is yearly. The declining formula would mean that the yearly supply limit for the first year of new Mainnet mining will be higher than for the second year, the second year’s higher than the third year’s, and so on. The yearly declining formula and these numbers will need to be finalized closer to the launch of the Open Network period of Mainnet once we will have seen how many Pioneers have KYC’ed and how much of their mined Pi they have transferred into Mainnet.

这样的年度供应限额将根据递减公式确定。根据诸如锁定比率和当时网络的剩余供应等因素，可以在更细粒度的基础上(例如按天)或者动态地通过更小的时间历元来计算年度限制。这种基于粒状时间历元的供应限制计算有助于实现更好、更平滑的时间分配曲线。为了简单起见，让我们假设时间纪元是一年。这个递减公式意味着，新 Mainnet 开采第一年的年供应限额将高于第二年，第二年高于第三年，以此类推。每年递减的公式和这些数字将需要在接近 Mainnet 开放网络时期推出时敲定，一旦我们看到有多少先锋已经 KYC‘和他们有多少被开采的 PI 转移到 Mainnet。

At Mainnet, Pioneers will be rewarded for their continued contributions to the growth and security of the network. As explained in the Mining section, Pioneer rewards will be further diversified because the network needs more diverse and in-depth contributions related to app usage, node operation, and Pi lockup. Pre-mainnet Pioneers will continue to contribute to Pi and mine from the Mainnet mining rewards, along with any new members joining the network, to ensure growth and longevity of the network.

在 Mainnet，先锋公司将获得奖励，以表彰他们为网络的发展和安全做出的持续贡献。正如挖掘部分所解释的，先锋奖励将进一步多样化，因为网络需要与 APP 使用、节点运营和 PI 锁定相关的更多样化和更深入的贡献。Mainnet 之前的先锋们将继续从 Mainnet 的采矿奖励中为 Pi 和 More 做出贡献，以及任何加入该网络的新成员，以确保网络的增长和寿命。

10 Billion Pi will be reserved for community organization and ecosystem building that will be, in the future, managed by a non-profit foundation. Most decentralized networks or cryptocurrencies, even though they are decentralized, still need an organization to organize the community and set the future direction of the ecosystem, e.g., Ethereum and Stellar. The future Pi foundation will (1) organize and sponsor community events, such as developer conventions, global online events and local community meetings, (2) organize volunteers and committee members, and pay full-time employees who are dedicated to building the community and ecosystem, (3) gather opinions and feedback from the community, (4) organize future community votings, (5) build branding and protect the reputation of the network, (6) represent the network to interact with other business entities including governments, traditional banks, and traditional enterprises, or (7) fulfill any number of responsibilities for the betterness of the Pi community and ecosystem. Further, in order to build a utilities-based Pi ecosystem, various community developer programs will be designed, created and carried out by the foundation to support community developers in the forms of grants, incubations, partnerships, etc.

将预留 100 亿 PI 用于社区组织和生态系统建设，未来将由一个非营利性基金会管理。大多数去中心化的网络或加密货币，即使它们是去中心化的，仍然需要一个组织来组织社区，并设定生态系统的未来方向，例如以太和恒星。未来的 PI 基金会将(1)组织和赞助社区活动，如开发者大会、全球在线活动和当地社区会议，(2)组织志愿者和委员会成员，并向致力于建设社区和生态系统的全职员工支付报酬，(3)收集社区的意见和反馈，(4)组织未来的社区投票，(5)建立品牌和保护网络的声誉，(6)代表网络与其他商业实体(包括政府、传统银行和传统企业)互动，或(7)履行任何数量的贝塔责任。此外，为了建立以公用事业为基础的 PI 生态系统，基金会将设计、创建和实施各种社区开发者计划，以赠款、孵化、合作等形式支持社区开发者。

5 billion Pi will be reserved for liquidity pools to provide liquidity for any ecosystem participants, including Pioneers and Pi apps developers. Liquidity is key for an ecosystem to be viable, active, and healthy. If businesses or individuals want to participate in ecosystem activities (e.g., by selling and buying goods and services in Pi), they must have timely access to Pi. Without liquidity, the ecosystem will not have a healthy flow of Pi, hence harming the creation of utilities.

将为流动资金池预留 50 亿 PI，为任何生态系统参与者提供流动性，包括先锋和 PI 应用程序开发人员。流动性是生态系统生存、活跃和健康的关键。如果企业或个人想要参与生态系统活动(例如，通过在 PI 中销售和购买商品和服务)，他们必须及时获得 PI。如果没有流动性，生态系统就不会有健康的 PI 流动，从而损害公用事业的创造。

As discussed in the Roadmap chapter, one benefit of the Enclosed Network period of the Mainnet is to allow calibrations on the token model, if any, based on the early Mainnet results. Therefore, the token model is subject to tweaking before the Open Network period starts. Also, in the future, for the health of the network and ecosystem, the network may face questions such as whether there needs to be any inflation after the completion of the distribution of the 100 Billion Pi. The inflation may be necessary to further incentivize contributions through more mining rewards, make up for any loss of Pi from circulation due to accidents or death, provide for more liquidity, mitigate hoarding that inhibits usage and utility creation, etc. At that time, the foundation and its committees specialized in these matters will organize and guide the community to reach a conclusion on the matter in a decentralized way.

正如路线图章节中所讨论的，封闭的 Mainnet 网络期的一个好处是允许根据早期的 Mainnet 结果对令牌模型(如果有的话)进行校准。因此，令牌模型会在开放网络时期开始之前进行调整。另外，在未来，为了网络和生态系统的健康，网络可能会面临千亿 PI 分配完成后是否需要有通胀等问题。通货膨胀可能是必要的，以通过更多的采矿奖励来进一步激励贡献，弥补因事故或死亡而造成的 PI 流通损失，提供更多的流动性，减轻阻碍使用和公用事业创造的囤积行为，等等。届时，专门从事这些事务的基金会及其委员会将组织和引导社区以分散的方式就此事达成结论。

Mining Mechanism 挖掘机制
Pi Network’s mining mechanism has been allowing Pioneers to contribute to the growth, distribution and security of the network and be rewarded in Pi meritocratically. The pre-Mainnet mining mechanism has helped the network achieve an impressive growth of over 30 million engaged members, a widely distributed currency and Testnet, and a trust graph of Security Circle aggregates that will feed the consensus algorithm of the Pi blockchain.

Pi Network 的挖掘机制一直允许先锋公司为网络的发展、分布和安全做出贡献，并在 Pi 中定期获得奖励。Pre-Mainnet 挖掘机制帮助网络实现了 3000 多万参与成员的惊人增长，广泛分布的货币和 Testnet，以及将为 PI 区块链的共识算法提供支持的 Security Circle 聚合的信任图。

Looking ahead into the Mainnet phase, Pi Network needs further contributions, as well as more diverse types of contributions from all its members, to become a true economy while continuing its growth and inclusion. In the Mainnet phase, we want to further achieve decentralization, utilities, stability and longevity, in addition to growth, inclusion, and security. These goals can only be achieved if all Pioneers in the network work together. Hence, the new Pi mining mechanism is designed to achieve these goals by incentivizing all Pioneers to contribute diversely to the network based on the same meritocratic principle. Below, we first describe the pre-Mainnet mining formula, followed by the changes in the Mainnet formula.

展望主网阶段，Pi Network 需要更多的贡献，以及所有成员更多样化的贡献，才能成为真正的经济体，同时继续增长和包容。在 Mainnet 阶段，除了增长、包容和安全之外，我们还希望进一步实现去中心化、公用事业、稳定性和长寿。这些目标只有在网络中的所有先锋人员共同努力的情况下才能实现。因此，新的 PI 挖掘机制旨在通过激励所有先锋公司基于相同的任人唯贤原则为网络做出不同贡献来实现这些目标。下面，我们首先描述 Mainnet 之前的挖掘公式，然后描述 Mainnet 公式的变化。

Pre-Mainnet Formula 公式
The pre-Mainnet mining formula demonstrates a meritocratic determination of a Pioneer’s hourly mining rate. Actively mining Pioneers received at least a minimum rate and were further rewarded for their contributions to security and growth of the network. The following formula determined the rate at which Pioneers mined Pi per hour:

Pre-Mainnet 采矿公式展示了先锋每小时采矿率的任人唯贤的决定。积极采矿的先锋们至少得到了最低费率，并因他们对网络安全和增长的贡献而获得进一步奖励。以下公式确定了先锋公司每小时开采 PI 的速度：

M = I(B, S) + E(I), where

M is the total Pioneer mining rate,
I is the Individual Pioneer base mining rate,
B is the systemwide base mining rate,
S is the Security Circle reward, which is a component of the individual Pioneer base mining rate from valid Security Circle connections, and
E is the Referral Team reward from active Referral Team members.
The systemwide base mining rate B started as 3.1415926 Pi/h and halved every time the network of Engaged Pioneers increased in size by a factor of 10x, starting at 1000 Pioneers. As listed below, there have been five halving events thus far:

M 是先锋公司的总开采率，
我是个人先锋基地开采率，
B 是整个系统的基本开采率，
S 是安全圈奖励，它是有效安全圈连接的个人先锋基本开采率的一个组成部分，以及。
E 是来自活跃的推荐团队成员的推荐团队奖励。
全系统的基本开采率 B 从 3.1415926 皮/小时开始，每增加一倍，从 1,000 名先锋开始，每增加一倍，采矿率就会减半。如下所示，到目前为止，已经有五个减半事件：

I(B,S) = B + S(B)

S(B) = 0.2 • min(Sc,5) • B, where
Sc is the count of valid Security Circle connections.

E(I) = Ec • I(B,S) • 0.25, where
Ec is the count of active Referral Team members who mine concurrently.

The mining formula can also be written as a multiple of B:

M = I(B,S) + E(I)

M = [B + S(B)] + [Ec • I(B,S) • 0.25], or

M = [B + {0.2 • min(Sc,5) • B}] + [Ec • 0.25 • {B + {0.2 • min(Sc,5) • B}}], or

M = B • [1 + {0.2 • min(Sc,5)} + {Ec • 0.25 • {1 + 0.2 • min(Sc,5)}}], or

M = B • [(1 + Ec • 0.25) • {1 + 0.2 • min(Sc,5)}]

Pre-Mainnet Systemwide Base Mining Rate 全系统基础采矿率
Every active Pioneer received at least the system wide base mining rate (B). That is, if Sc = 0 and Ec = 0 in the mining formula above, then M = B. In any case, the total Pioneer mining rate was a multiple of the systemwide base mining rate. The value of B was pre-determined before the Mainnet, and as shown in the table above, it changed only five times. The max supply was undetermined due to the dynamic progress of the pre-Mainnet mining mechanism, e.g. how large the network is and how fast the network reaches the next halving event. It would only be determined when B dropped to 0. However, as explained in the next section, the value of B at Mainnet is calculated in real time, dynamically adjusting based on the total annual Pi supply and the total mining coefficient across all the Pioneers. The supply of Pi is finite at Mainnet

每个活跃的先锋至少得到系统范围内的基础采矿率(B)。也就是说，在上面的挖掘公式中，如果 SC=0 和 EC=0，则 M=B。在任何情况下，先锋公司的总开采率都是系统范围基本开采率的倍数。B 的值是在 Mainnet 之前预先确定的，如上表所示，它只更改了五次。由于 Pre-Mainnet 挖掘机制的动态进展，例如网络有多大以及网络到达下一个减半事件的速度，最大供应量无法确定。只有当 B 降到 0 时才能确定。然而，正如下一节所述，Mainnet 的 B 值是实时计算的，根据每年 PI 供应总量和所有先锋公司的总开采系数动态调整。主网中 PI 的供给是有限的

Security Circle Reward 安全圈奖励
Pi’s consensus algorithm relies on a global trust graph, which is aggregated from the millions of intertwining Security Circles of individual Pioneers. Thus, a Pioneer was rewarded with additional Pi per hour for each new valid Security Circle connection, up to 5 such connections. The Security Circles are so central to the security of the Pi blockchain that the Security Circle reward raised the total Pioneer mining rate in two ways:

Pi 的共识算法依赖于一个全局信任图，该信任图是由数百万个相互交织的先锋安全圈聚合而成的。因此，对于每个新的有效安全圈连接，先锋每小时可获得额外的 PI 奖励，最多可达 5 个此类连接。安全圈对 PI 区块链的安全至关重要，安全圈奖励通过两种方式提高了先锋总开采率：

by directly adding to the individual Pioneer base mining rate (I), and by boosting the Referral Team reward, if any.

直接增加个人先锋基地开采率(I)，并提高推荐团队奖励(如果有的话)。
In fact, a full Security Circle—that is, having at least five valid connections—doubled both the individual Pioneer base mining rate and the Referral Team reward.

事实上，一个完整的安全圈子--也就是至少有五个有效的联系--会使个人先锋基地的开采率和推荐团队的奖励都翻一番。

Referral Team Reward 推荐团队奖励
Pioneers can also invite others to join Pi Network and form their Referral Team. The inviter and invitee share an equal split of the Referral Team bonus rewards, that is a 25% boost to their respective individual Pioneer base mining rates, whenever both are mining concurrently. Pioneers mined more Pi per hour with each concurrently mining Referral Team member. This Referral Team reward recognized the Pioneers’ contribution to the growth of the network and the distribution of the Pi token.

先驱者也可以邀请其他人加入 PI Network，组成他们的推荐团队。邀请者和被邀请者平分推荐团队的奖金奖励，即当双方同时开采时，他们各自的先锋基地采矿率将增加 25%。先锋们每小时挖掘更多的 PI，同时挖掘转诊团队的每个成员。这项推荐团队奖励表彰了先锋队对网络发展和 PI 令牌分发的贡献。

Mainnet Mining Formula 挖掘公式
The goals of the Mainnet phase are to make further progress in decentralization and utilities, ensure stability and longevity, and retain growth and security. The new formula, as written below, incentivizes more diverse contributions of Pioneers to support these Mainnet goals while retaining the incentives to secure and grow the network. As before, it is meritocratic and expressed as the rate at which Pioneers mine Pi per hour.

主网阶段的目标是在权力下放和公用事业方面取得进一步进展，确保稳定和长寿，并保持增长和安全。如下所述，新方案激励先锋公司做出更多样化的贡献，以支持这些 Mainnet 目标，同时保留保护和发展网络的激励措施。和以前一样，它是任人唯贤的，用先驱者每小时开采圆周率来表示。

M = I(B,L,S) + E(I) + N(I) + A(I) + X(B), where

M is the total Pioneer mining rate,
I is the individual Pioneer base mining rate,
B is the systemwide base mining rate (adjusted based on the available pool of Pi to distribute for a given time period),
L is the lockup reward, which is a new component of the individual Pioneer base mining rate,
S is the the Security Circle reward, which is a component of the individual Pioneer base mining rate from valid Security Circle connections the same way as in the pre-Mainnet mining formula,
E is the Referral Team reward from active Referral Team members the same way as in the pre-Mainnet mining formula,
N is the Node reward,
A is the Pi apps usage reward, and
X are new types of contributions necessary for the network ecosystem in the future, which will be determined later, but will also be designed as a multiple of B.

M 是先锋公司的总开采率，
我是个人先锋基地开采率，
B 是系统范围的基本采矿率(基于在给定时间段内分配的可用 PI 池进行调整)，
L 是禁闭奖励，这是个人先锋基地采矿率的一个新组成部分，
S 是安全圈奖励，它是有效安全圈连接的个人先锋基本开采率的一个组成部分，其方式与 Pre-Mainnet 挖掘公式中的相同。
E 是来自活动推荐团队成员的推荐团队奖励，其方式与 Pre-Mainnet 挖掘公式中的方式相同。
N 是节点奖励，
A 是 PI 应用程序使用奖励，以及。
X 是未来网络生态系统所需的新类型贡献，将在稍后确定，但也将设计为 B 的倍数。
In short, S and E remain the same as in the pre-Mainnet mining formula, while new rewards such as L, N and A have been added to the current formula. L is added as part of I; N and A are added as additional rewards calculated based on I. In other words, the network still rewards growth through E and security through S, while incentivizing Pioneers’ contributions to running nodes for decentralization through N, using apps for utilities creation through A, and locking up for stability especially during the initial years through L. Further, new types of rewards to Pioneers through X in the future may be added for building a fully functioning ecosystem, such as rewards for Pioneer developers creating successful Pi apps. B continues to exist over a long period of time while having a yearly cap to ensure longevity of network growth while maintaining scarcity. In fact, all the rewards can be expressed in B as follows.

简而言之，S 和 E 与 Pre-Mainnet 挖矿公式保持不变，而在当前公式中增加了 L、N 和 A 等新的奖励。L 是作为 I 的一部分添加的；N 和 A 是作为基于 I 计算的额外奖励而添加的。换句话说，网络仍然通过 E 奖励增长，通过 S 奖励安全，同时通过 N 激励先锋对运行节点的贡献，通过 A 使用应用创建公用事业，并通过 L 锁定稳定性。此外，未来可能会通过 X 增加对先锋的新型奖励，以建立一个功能齐全的生态系统，例如奖励先锋开发人员创建成功的 PI 应用。B 在很长一段时间内继续存在，同时有年度上限，以确保网络增长的持久性，同时保持稀缺性。事实上，所有的奖励都可以用 B 表示如下。

Here,

I(B,L,S) = B + S(B) + L(B)
S(B) = 0.2 • min(Sc,5) • B, where
Sc is the count of valid Security Circle connections.
E(I) = Ec • 0.25 • I(B,L,S), where
Ec is the count of active Referral Team members.
L(B) = Lt • Lp • log(N) • B, where
Lt is a multiplier corresponding to the duration of a lockup,
Lp is the proportion of Pioneer’s mined Pi on the Mainnet that is locked up with the maximum being 200%, and
N is the total number of Pioneer's mining sessions preceding the current mining session.
N(I) = node_factor • tuning_factor • I, where
Node_factor = Percent_uptime_last_1_days • (Uptime_factor + Port_open_factor + CPU_factor), where

Uptime_factor = (Percent_uptime_last_90_days + 1.5*Percent_uptime_last_360_days(360-90) + 2* Percent_uptime_last_2_years + 3*Percent_uptime_last_10_years),
Port_open_factor = 1 + percent_ports_open_last_90_days + 1.5*percent_ports_open_last_360_days + 2* percent_ports_open_last_2_years + 3*percent_ports_open_last_10_years,
CPU_factor = (1 + avg_CPU_count_last_90_days + 1.5*avg_CPU_count_last_360_days + 2* avg_CPU_count_last_2_years + 3*avg_CPU_count_last_10_years)/4.

Percent_uptime_last_*_days/years is the percentage of the last * time period when the individual Node was live and accessible by the network.

rcent_UPTime_Last_*_Days/Years 是过去*个节点处于活动状态且可由网络访问的时间段的百分比。
percent_ports_open_last_*_days/years is the percentage of the last * time period when the ports of the individual Node were open for connectivity to the network.

PERCENT_PORTS_OPEN_LAST_*_DYES/Year 是指在过去*个时间段内，单个节点的端口打开以连接到网络的百分比。
avg_CPU_count_last_*_days/years is the average CPU that the individual Node provided to the network during the last * time period.
tuning_factor is a statistical factor that normalizes the node_factor to a number between 0 and 10.
AVG_CPU_COUNT_LAST_*_Days/Years 是单个节点在过去*时间段内向网络提供的平均 CPU。
Tuning_factor 是一个统计因子，它将 node_factor 归一化为 0 到 10 之间的一个数字。
A (I)* =

) ] • I

time_spent_per_app_yesterday_in_seconds is, for each Pi app, the total amount of time in seconds that the Pioneer spends using the app on the prior day.

Time_Spend_PER_APP_YORTHED_IN_Second 是对于每个 PI 应用程序，先锋在前一天使用该应用程序所花费的总时间(以秒为单位)。
Σ_across_apps sums up the logarithmic value of the Pioneer’s time_spent_per_app_yesterday_in_seconds across all the Pi apps.
avg_daily_time_across_apps_last_* is the average daily time in seconds the Pioneer spends across all the Pi apps in the aggregate during the last * time period.

AVG_DAILY_TIME_CROSS_APPS_LAST_*是先锋在过去*时间段内在聚合的所有 PI 应用上花费的平均每日时间(以秒为单位)。

* Note that when any of the logarithmic functions returns an undefined value or a value below 0 (that is, when, the input to the logarithmic function is below 1), the formula resets the value of the logarithmic function to be 0 in order to avoid negative mining rewards or an error in the function.

*请注意，当任何对数函数返回未定义的值或低于 0 的值时(即，当对数函数的输入低于 1 时)，该公式将对数函数的值重置为 0，以避免负挖掘奖励或函数中的错误。

X(B) is to be determined in the future based on the new types of contributions, but will be a multiple of B and kept within the yearly supply limit along with other rewards.

X(B)将在未来根据新的捐款类型确定，但将是 B 的倍数，并与其他奖励一起保持在每年的供应限额内。
As shown above, the expressions of S and E remain the same as in the pre-Mainnet mining formula, and will not be explained further here. Next, we will focus on explaining the changes to B, changes to I through L, and the additions of N and A.

如上所示，S 和 E 的表达式与 Pre-Mainnet 挖掘公式中的表达式相同，在此不再赘述。接下来，我们将重点解释对 B 的更改、对 I 到 L 的更改以及 N 和 A 的添加。

Systemwide Base Mining Rate 全系统基础采矿率

Like in Pre-Mainnet mining, all of the terms in the Mainnet mining formula above can be expressed in Pi per hour and are designed to be a multiple of B. Hence, the equation can also be re-written as below. Every Pioneer can mine at least the Systemwide Base Mining Rate everyday, and will be able to mine at a higher rate if they also have other types of contributions that are calculated as multiples of B.

就像在 Pre-Mainnet 挖掘中一样，上面 Mainnet 挖掘公式中的所有项都可以用每小时 PI 表示，并且被设计为 B 的倍数。因此，该公式也可以重写如下。每个先驱者每天至少可以开采系统范围的基础采矿率，并且如果他们还有其他类型的贡献(以 B 的倍数计算)，将能够以更高的采矿率进行开采。

M = B • (1 + S + L) • (1 + N + E + A + X)

Unlike in the pre-Mainnet mining, B in Mainnet mining as in the formula above is no longer a constant across all Pioneers at a given point in time, but is calculated in real time and dynamically adjusted based on a yearly supply cap.

与 Pre-Mainnet 开采不同，Mainnet 开采中的 B 不再是所有先锋公司在给定时间点的常数，而是实时计算并根据每年的供应上限进行动态调整。

Given a yearly supply limit, it is impossible to keep a constant B like in the pre-Mainnet period because it’s unpredictable how much each Pioneer mines and how many Pioneers are actively mining during a period of time. The pre-Mainnet model was designed to incentivize growth during the beginning years to bootstrap the network. As the network achieves a certain scale, it also needs to ensure the overall health of the ecosystem. Therefore, an exponential issuance of the tokens through exponential network growth and a constant mining rate does not make sense any longer. The shift of B from being a constant to being dynamically adjusted throughout the year results from the need to incentivize Pioneers’ contributions meritocratically but also to keep the total rewards within a limit.

考虑到每年的供应限制，不可能像前 Mainnet 时期那样保持恒定的 B，因为无法预测每个先锋公司在一段时间内开采了多少矿，以及有多少先锋公司在积极开采。Pre-Mainnet 模式旨在激励最初几年的增长，以引导网络。随着网络达到一定规模，还需要保证生态系统的整体健康。因此，通过指数网络增长和恒定的挖掘率指数发行令牌已不再有意义。B 从恒定到全年动态调整的转变是因为需要按价值顺序激励先锋的贡献，同时也是为了将总奖励保持在一定的范围内。

Thus, to solve the yearly limit problem while ensuring fairness for whoever mined Pi, B of a given day in the year is calculated as below. Here a day is defined as the last 24 hours before the moment a Pioneer starts a new mining session. Hence, different Pioneers will have slightly different days relative to their time of mining, and thus, potentially a slightly different B based on the calculation below. Each Pioneer’s B of their day stays constant through their mining session, that is, over the next 24 hours from the moment they start their mining session. B is calculated as follows:

因此，为了解决年度限制问题，同时确保开采 Pi 的人的公平性，一年中给定日期的 B 计算如下。在这里，一天的定义是先驱者开始新的采矿作业前的最后 24 小时。因此，不同的开拓者相对于他们的采矿时间会有略微不同的天数，因此，根据下面的计算，可能会有略有不同的 B。每个先锋一天中的 B 值在他们的采矿过程中保持不变，也就是从他们开始采矿过程的那一刻起，在接下来的 24 小时内保持不变。B 的计算方法如下：

Divide the remaining total Pi supply of the year by the number of days left in the year to get day_supply based on the remaining yearly supply,

将一年中剩余的总 PI 供应量除以一年中剩余的天数，得到基于每年剩余供应量的 DAY_SUPPLICATION。

add the multiples of B from all Pioneers actively mining within the last 24 hours, which represents a diverse set of Pioneers’ contributions, in the Mainnet mining formula above to get the sum_of_B_multiples of the whole network for that 24-hour window, and

further divide day_supply by sum_of_B_multiples and 24 hours to get B of that specific mining session.

在上面的 Mainnet 挖掘公式中，将过去 24 小时内活跃挖掘的所有先锋公司的 B 的倍数相加，以获得整个网络在该 24 小时窗口内的和 _of_B_Multiples，该倍数代表先锋公司的不同贡献集合，以及。将 DAY_SUPPLACE 除以 SUM_OF_B_Multiplies 和 24 小时，得到该特定挖掘会话的 B。

Hence, for a given day of the year,
B = day_supply / (sum_of_B_multiples • 24h)

Under this framework, B on different days of the year will be different depending on how many Pioneers mined in the last 24 hours as well as what and how much contributions they made to receive the extra multiples of B by running nodes, using utilities apps or lockups, etc. This model also addresses any uncertainty with having X(B)—future types of contribution rewards for Pioneers—in the formula. Regardless of how much X is going to be, it will be kept within the same yearly supply limit without increasing the total supply and will only affect the division of rewards among different types of contributions. This dynamic mechanism allows Pioneers themselves, in a decentralized way, to make sure that (1) the rewards do not exceed the yearly supply limit, (2) the distribution of the yearly supply does not end early in the year, and (3) the rewards are divided meritocratically.

在这一框架下，一年中不同日期的 B 将会有所不同，这取决于过去 24 小时内开采的先锋人数，以及他们通过运行节点、使用公用事业应用程序或锁定等方式为获得 B 的额外倍数所做的贡献和贡献。该模型还解决了公式中存在 X(B)-先锋的未来贡献奖励类型-的任何不确定性。无论 X 是多少，它都将保持在相同的年度供应限额内，而不会增加总供应量，并且只会影响不同类型的贡献之间的奖励分配。这种动态机制允许先锋们自己以分散的方式确保：(1)奖励不超过每年的供应限额；(2)每年的供应不会在年初结束；(3)奖励是按功绩分配的。

For purposes of illustration, let’s suppose there are only two Pioneers on a given day and B is the mining rate (expressed in Pi/day for this illustration)—a constant during a specific Pioneer mining session, but dynamically adjusted across different days:

为了说明起见，假设在给定的一天只有两个 Pioneer，B 是挖掘率(在此图示中以 PI/day 表示)-在特定 Pioneer 挖掘会话期间的常量，但在不同的日期动态调整：

Pioneer 1 has no app engagement (A=0), is not operating a Node (N=0), has no security connections (S=0), and has no active Referral Team members (E=0). They are in their 11th mining session (N=10) and are locking up 100% of their mined Pi (Lp=1) for 3 years (Lt=2). Pioneer 1’s mining rate on this day is:

先锋 1 没有应用程序合约(A=0)，没有运行节点(N=0)，没有安全连接(S=0)，也没有活动的推荐团队成员(E=0)。他们正在进行第 11 次开采(N=10)，并将其开采的 PI(Lp=1)100%锁定 3 年(Lt=2)。这一天先锋一号的开采率是：

M1 = I(B,L,S) + 0 + 0 + 0, or
M1 = B + {2 • 1 • log(10)} • B + 0, or
M1 = 3B

Pioneer Base Mining rate 先锋基地采矿率
By comparison, the individual Pioneer base mining rate in the pre-Mainnet mining formula includes only system-wide base mining rate and Security Circle rewards. At Mainnet, a new component, lockup reward, is added to individual Pioneer base mining rate I. Lockup rewards L, along with the system-wide base mining rate B and Security Circle reward S, constitute the individual Pioneer base mining rate I. Since I is used as an input to calculate all the other rewards, as a result, the Security Circle and lockup rewards enhance the total Pioneer mining rate by: (1) by directly adding to the individual Pioneer base mining rate and (2) by boosting the any Referral Team reward E, nodes reward N, and app usage reward A.

相比之下，Pre-Mainnet 采矿公式中的个人先锋基地采矿率只包括全系统基础采矿率和安全圈奖励。在 Mainnet，在个人先锋基础采矿率 I 中增加了一个新的组成部分，锁定奖励 L，与系统范围的基础采矿率 B 和安全圈奖励 S 一起构成了个人先锋基础采矿率 I。由于 I 被用作计算所有其他奖励的输入，因此，安全圈和锁定奖励通过以下两种方式提高了总先锋采矿率：(1)直接添加到个人先锋基础采矿率；(2)通过提高任何奖励

Lockup Reward锁定奖励
At Mainnet, the lockup reward is meant to support a healthy and smooth ecosystem and incentivize long-term engagement with the network, while the network is bootstrapping the economy and creating demands. It is an important decentralized macroeconomic mechanism to moderate circulating supply in the market, especially in the early years of the open market when utilities are being created. One important goal of the Pi Network is to create a utility-based ecosystem of apps. Transactions for real goods and services in the ecosystem, rather than just speculative trading, are intended to determine the utility of Pi. As we launch the Enclosed Network phase of the Mainnet, one of the main areas of focus will be to support and grow the Pi app developer community and nurture more Pi apps to grow. In the meantime, Pioneers can choose to lock up their Pi to help create a stable market environment for the ecosystem to mature and for more Pi apps to emerge and provide compelling use cases for spending Pi – to ultimately create organic demands through utilities.

在 Mainnet，锁定奖励旨在支持一个健康、顺畅的生态系统，并激励与网络的长期互动，同时网络正在引导经济并创造需求。调节市场循环供给是一种重要的分散的宏观经济机制，尤其是在公用事业公司产生的公开市场初期。PI Network 的一个重要目标是创建一个基于实用程序的生态系统。生态系统中真实商品和服务的交易，而不仅仅是投机性交易，意在确定 PI 的效用。随着我们启动 Mainnet 的封闭式网络阶段，其中一个主要的重点领域将是支持和发展 PI 应用程序开发社区，并培育更多的 PI 应用程序以实现增长。与此同时，先锋们可以选择锁定他们的 PI，以帮助为生态系统的成熟和更多 PI 应用的出现创造一个稳定的市场环境，并为花费 PI 提供令人信服的使用案例-最终通过公用事业创造有机需求。

The lockup reward formula is reprinted here:

L(B) = Lt • Lp • log(N) • B, where
Lt is the Lockup Time period multiplier of B.

0 → Lt = 0
2 weeks → Lt = 0.1
6 months → Lt = 0.5
1 year → Lt = 1
3 years → Lt = 2
Lp is the Lockup Percentage multiplier of B, where
the Lockup Percentage is the lockup amount over the Mainnet Balance transferred from one’s previous mining rewards (Lb), and the Lockup Percentage multiplier is as follows.
0% → Lp = 0
25% → Lp = 0.25
50% → Lp = 0.5
90% → Lp = 0.9
100% → Lp = 1.0
150% → Lp = 1.5
200% → Lp = 2
log(N) is the logarithmic value of the total number of previous mining sessions (N).

Pioneers will have the opportunity to voluntarily lock up their Pi to earn the right to mine at a higher rate. First of all, the prerequisite of the lockup reward is that the Pioneer must be actively mining. Without mining in the first place, there will be no lockup rewards for any inactive mining sessions, even if Pi is locked up. As expressed in the formula above, all that the lockup does is to provide multipliers to B, so there will be no lockup rewards if B is 0 (which means the Pioneers is not mining).

开拓者将有机会自愿锁定他们的 PI，以获得更高的采矿权。首先，禁闭奖励的前提是先锋必须在积极开采。在没有挖掘的情况下，即使 PI 被锁定，任何非活动的挖掘会话也不会有锁定奖励。正如上面的公式所表示的，锁定所做的一切就是为 B 提供乘数，因此如果 B 为 0(这意味着先锋不是在开采)，则不会有锁定奖励。

Secondly, the lockup reward is positively associated with the contribution to the lockup, i.e. the duration of the lockup time period (Lt) and the amount locked up. However the lockup amount is accounted for by the percentage of a Pioneer’s total Pi mined (Lp). The maximum Pi that a Pioneer can lock up is twice as much as their Mainnet Balance that got transferred from their prior mining in the mobile app (Lb), i.e. 200% Lb. The reasons for having a 2X maximum lockup amount of one’s transferred Mainnet Balance (Lb) are to 1) prevent exploitation of the lockup reward and 2) further encourage other contributions to the Pi ecosystem, such as further boosting their mining, running nodes and using apps. This, in a sense, favors Pioneers who mine and make other types of contributions to the network.

其次，锁定期的长短和锁定额与锁定期的贡献呈正相关关系，即锁定期的长短和锁定期的大小。(2)锁定期的长短与锁定期的大小呈正相关。然而，锁定的数量是由先锋队开采的总 PI(LP)的百分比来计算的。先锋可以锁定的最大 PI 是他们之前在移动应用程序(Lb)中挖掘得到的主余额的两倍，即 200%lb。一个人转移的主网余额(Lb)的最大锁定额为 2 倍的原因是：1)防止利用锁定奖励，2)进一步鼓励对 PI 生态系统的其他贡献，如进一步促进他们的挖掘、运行节点和使用应用程序。从某种意义上说，这有利于那些挖掘矿藏并为网络做出其他类型贡献的先锋们。

Thirdly, Log(N) offers a higher lockup incentive to Pioneers who have a long mining history and presumably a large transferable balance to lock up. While the lockup reward formula generally favors equality by accounting for not the absolute amount but the percentage of their transferred balance (Lp) — which allows smaller accounts with a short mining history to lock up small amounts and yet receive the same lockup reward multiplier as big accounts — we need to add a Log(N) factor that accounts for miners with a long mining history, to counterbalance the bias in favor of Pioneers with small balances and provide enough incentive for long-history Pioneers with bigger balances. However, the effect of mining history on lockup rewards also needs to be capped. Thus, the formula applies a logarithm to the number of previous mining sessions N. For example, if a Pioneer mined almost everyday for the last 3 years, their total previous mining sessions (N) will be about 1,000. In this scenario, Log(1,000) equals 3, adding another multiplier to B in their lockup rewards. Keep in mind that to achieve meaningful lockup rewards for long-mining-history Pioneers, the amount of Pi they have to lock up is much more than smaller accounts.

第三，Log(N)为那些有较长采矿历史和可能有大量可转移余额要锁定的先锋提供了更高的锁定激励。虽然锁定奖励公式通常倾向于平等，因为它不考虑绝对金额，而是其转移余额(LP)的百分比-这允许采矿历史较短的小账户锁定小金额，但获得与大账户相同的锁定奖励乘数-我们需要添加一个 Log(N)因子，以考虑到拥有长期采矿历史的矿工，以抵消对余额较小的先锋公司的偏见，并为余额较大的长期先锋公司提供足够的激励。然而，采矿历史对锁定奖励的影响也需要加以限制。因此，该公式对以前的采矿会话数 N 应用对数。例如，如果一个先驱者在过去 3 年中几乎每天都采矿，那么他们以前的采矿会话总数(N)将约为 1,000 次。在这个场景中，Log(1,000)等于 3，在他们的锁定奖励中将另一个乘数加到 B。请记住，要为长期从事采矿的先锋获得有意义的锁定奖励，他们必须锁定的 PI 数量远远多于较小的账户。

Fourthly, one Pioneer can voluntarily have multiple lockups at different times with different amounts and durations. The calculation of the total lockup rewards for this Pioneer with i number of different lockups is to find the total lockcup reward multiplier of B, as expressed in the formula below. The formula below is the equivalent to the lockup reward formula above, with the only difference being that it accounts for multiple lockups of the same Pioneer to calculate their total lockup rewards, e.g. different durations (Lti) and different amounts (Lci) of each lockup at different time:

第四，一个先锋可以自愿在不同的时间拥有不同数量和持续时间的多次禁闭。不同锁定次数为 i 的该先锋的总锁定奖励的计算方法是求出 B 的总锁定奖励倍数，如下面的公式所示。下面的公式等同于上面的禁闭奖励公式，唯一不同的是，它考虑了同一先锋的多次禁闭来计算他们的总禁闭奖励，例如，不同时间不同的禁闭持续时间(LTI)和不同的禁闭金额(LCI)

The purpose of this formula is to calculate the total lockup rewards based proportionally on each lockup’s amount (Lc) over the total Mainnet Balance from previous mining (Lb) as a weight, multiplied by their respective lockup time period (Lt) and Log(n). So that, even though there are multiple lockups of the same Pioneer, more lockups with different settings will proportionally add to their total lockup rewards. The values of Lt, Lc, and log(N) are calculated and multiplied for each lockup i and then summed across various i’s, which is then divided by the value of Lb at a given mining session, to arrive at the value of L(B) for that mining session. This formula ensures that regardless of the Lb, as long as the Pioneer maintains the same percentage of their lockup amount over their Lb, the total lockup rewards multiplier will remain the same.

此公式的目的是根据每次锁定金额(Lc)占前一次开采的总主要余额(Lb)的权重，乘以各自的锁定时间段(Lt)和 Log(N)，按比例计算总锁定奖励。因此，即使同一先锋有多个锁定，不同设置的更多锁定将按比例增加其总锁定奖励。针对每个锁定 i 计算 lt、lc 和 log(N)的值并将其相乘，然后在各个 i 上求和，然后将其除以给定挖掘会话的 lb 的值，以得出该挖掘会话的 L(B)的值。这个公式确保，无论磅值如何，只要先锋的锁定期金额与磅值保持相同的百分比，那么总的锁定期奖励乘数将保持不变。

Lastly, when can a Pioneer lock up Pi? Pioneers can decide their lockup duration and lockup percentage of their transferable balance anytime they want as an overall account setting in the Pi app. They can even preselect these settings before they’re KYC’ed or ready to migrate to the Mainnet. As they and their Referral Team/Security Circle pass KYC, more of their Mobile Balance will become transferable. At the moment of the migration of their Transferable Balance to Mainnet, their preselected setting of lockup duration and percentage will automatically apply to the amount of balance transferred, resulting in two types of balances on the Mainnet: lockup balance and free balance, both of which will be recorded on the Mainnet blockchain and reside in the Pioneer’s non-custodial Pi wallet. Thus, lockups cannot be reversed once confirmed and must remain locked up for the entirety of the chosen duration due to the nature of blockchain. Any changes to this Pioneer's lockup setting will take effect in their next balance transfer to the Mainnet.

最后，开拓者什么时候才能把派关起来？开拓者可以随时决定他们的锁定时间和可转移余额的锁定百分比，作为 PI 应用程序中的整体账户设置。他们甚至可以在 KYC 或准备迁移到 Mainnet 之前预先选择这些设置。当他们和他们的推荐团队/安全圈通过 KYC 时，他们的移动余额中将有更多可以转移。在他们的可转移余额迁移到 Mainnet 的那一刻，他们预先选择的锁定时间和百分比设置将自动应用于转移的余额金额，从而在 Mainnet 上产生两种类型的余额：锁定余额和自由余额，这两种余额都将记录在 Mainnet 区块链上，并驻留在先锋的非托管 Pi 钱包中。因此，锁定一旦确认就不能撤销，并且由于区块链的性质，必须在所选的整个持续时间内保持锁定。对此先锋的锁定设置所做的任何更改都将在下一次将余额转移到主网时生效。

This account-wide lockup setting allows Pioneers to lock up a maximum of 100% of their transferable balance from mobile to Mainnet. After Mainnet launches and Pioneers transfer their balances, Pioneers can also lock up more Pi directly on the Mainnet through a slightly different lockup interface later on. At that time, Pioneers can lock up as much as 200% of their already-transferred Mainnet balance acquired from their previous mining. The additional lockup allowance for more Pi than individually mined by the Pioneer can come from utility-based Pi apps transactions, i.e., making Pi from selling goods and services.

这个账户范围的锁定设置允许先锋锁定最多 100%的可从移动设备转移到主网的余额。在主网发射和先锋转移他们的余额之后，先锋也可以在稍后通过一个稍微不同的锁定界面直接在主网上锁定更多的 PI。届时，先锋公司可以锁定其已转移的 Mainnet 余额的高达 200%，这些余额是从之前的开采中获得的。比先驱者单独开采的更多 PI 的额外锁定额度可以来自基于公用事业的 PI 应用交易，即通过销售商品和服务来获得 PI。

App Usage Reward 使用奖励
An overarching goal of the Pi Network is to build an inclusive peer-to-peer economy and online experience fueled by the Pi cryptocurrency through our app ecosystem. Therefore, Pioneers will have additional mining rewards for using Pi apps on the Pi apps platform through the Pi Browser, including ecosystem apps and third-party apps in the Pi Directory. The app usage reward for Pioneers helps the ecosystem in two ways.

First, it will give Pi app developers market access and increased impressions of their apps. Pi app developers will gain usage and product iteration opportunities from Pioneers, which has been one of the biggest barriers to creating viable decentralized applications in the blockchain industry. Decentralized application (dApp) developers do not yet have a plentiful, stable, and utility-seeking consumer market environment to test and hone their consumer products to create consumer utilities. Pi Network’s apps platform and the app usage reward are meant to provide that environment for dApp developers.

首先，它将让 PI 应用程序开发者进入市场，并增加对他们的应用程序的印象。PI 应用开发者将从先锋获得使用和产品迭代机会，这一直是在区块链行业创建可行的去中心化应用的最大障碍之一。分散式应用程序(DAPP)开发人员还没有一个充足、稳定和追求效用的消费市场环境来测试和磨练他们的消费产品来创建消费效用。Pi Network 的应用程序平台和应用程序使用奖励旨在为 DAPP 开发人员提供这种环境。

Second, the increased impressions and usage will potentially lead to increased spending of Pi by Pioneers in the Pi apps, thus increasing utility-based Pi demand in the market. Even though the impressions are incentivized through the app usage reward, the spending of Pi is not. This means that the Pi app usage reward to Pioneers helps the Pi app developers to the extent that Pioneers are at their door. Now what determines whether Pioneers will actually stay and spend Pi in their apps is how useful and engaging their products are and what values the apps can provide for Pioneers. This framework ensures that, for the purpose of Pi demand creation, organic market forces are at work that allow apps to compete on the basis of product quality and utility, ultimately allowing the best apps to emerge and stay in the market and generate real utilities and even more Pi demands.

其次，印象和使用量的增加可能会导致先锋公司在 PI 应用程序中对 PI 的支出增加，从而增加市场上基于公用事业的 PI 需求。尽管这些印象是通过应用程序使用奖励来激励的，但 PI 的支出并不是这样。这意味着，对 Pioneers 的 PI 应用程序使用奖励可以帮助 PI 应用程序开发人员在 Pioneers 就近的情况下进行开发。现在，决定先锋公司是否真的会留下来并在他们的应用程序中花费 PI 的是他们的产品有多有用和参与度有多高，以及这些应用程序可以为先锋公司提供什么价值。这个框架确保，为了创造 PI 需求，有机的市场力量正在发挥作用，允许应用程序在产品质量和实用程序的基础上竞争，最终允许最好的应用程序出现并留在市场上，产生真正的实用程序，甚至更多的 PI 需求。

Through the above two mechanisms, the app usage reward aims to achieve the gradual transition from extrinsic incentives to intrinsic motivations among Pioneers visiting Pi apps, and thus the transition from incentivized to organic usage of Pi apps in order to ultimately bootstrap a utility-based ecosystem of apps using Pi.

通过以上两个机制，应用使用奖励旨在实现访问 PI 应用的先锋从外部激励到内在动机的逐步过渡，从而实现 PI 应用从激励性到有机使用的过渡，从而最终引导使用 PI 的基于效用的应用生态系统。

The app usage reward formula is reprinted here:

A (I)* =
log [ Σ_across_apps { log(time_spent_per_app_yesterday_in_seconds) } ] • log [ log( 0.8 • avg_daily_time_across_apps_last_30_days + 0.6 • avg_daily_time_across_apps_last_90_days + 0.4 • avg_daily_time_across_apps_last_180_days + 0.2 • avg_daily_time_across_apps_last_1_year + 0.1 • avg_daily_time_across_apps_last_2_year ) ] • I

time_spent_per_app_yesterday_in_seconds is, for each Pi app, the total amount of time in seconds that the Pioneer spends using the app on the prior day.

Time_Spend_PER_APP_YORTHED_IN_Second 是对于每个 PI 应用程序，先锋在前一天使用该应用程序所花费的总时间(以秒为单位)。
Σ_across_apps sums up the logarithmic value of the Pioneer’s time_spent_per_app_yesterday_in_seconds across all the Pi apps.
avg_daily_time_across_apps_last_* is the average daily time in seconds the Pioneer spends across all the Pi apps in the aggregate during the last * time period.

Σ_OVERS_APPS 汇总所有 PI 应用程序中先锋应用程序的 Time_Spend_PER_APP_YOYD_IN_ 秒的对数值。
AVG_DAILY_TIME_CROSS_APPS_LAST_*是先锋在过去*时间段内在聚合的所有 PI 应用上花费的平均每日时间(以秒为单位)。

* Note that when any of the logarithmic functions returns an undefined value or a value below 0 (that is, when, the input to the logarithmic function is below 1), the formula resets the value of the logarithmic function to be 0 in order to avoid negative mining rewards or an error in the function.

*请注意，当任何对数函数返回未定义的值或低于 0 的值时(即，当对数函数的输入低于 1 时)，该公式将对数函数的值重置为 0，以避免负挖掘奖励或函数中的错误。

Generally, the app usage reward formula takes into account two factors: time spent in apps and the number of apps used while crediting the history of app usage in the long term and capping the rewards to avoid exploitation. There are two main parts to the formula. The first part aggregates a Pioneer’s time spent across each app in the last mining session (i.e., in the previous day). The logarithmic function provides a positive function with diminishing returns, meaning that an increase in time spent on any one app will generally increase the rewards, but the positive effect of time spent on rewards decreases as more time is spent. This setup encourages Pioneers to generally spend more time on multiple diverse apps, helping the network to bootstrap the creation of diverse utilities. At the same time, it caps the rewards to prevent users from exploiting this reward by artificially keeping the apps open all day, which would not meaningfully contribute to utilities creation.

一般来说，APP 使用奖励公式会考虑两个因素：花费在 APP 上的时间和使用的 APP 数量，同时长期计入 APP 使用历史，并设置奖励上限以避免利用。这个公式有两个主要部分。第一部分汇总了 Pioneer 在上一次挖掘会话中(即前一天)在每个应用程序上花费的时间。对数函数提供了一个回报递减的正函数，这意味着花在任何一款应用上的时间增加通常会增加奖励，但花在奖励上的时间的积极影响随着时间的增加而减少。这种设置鼓励先锋们通常在多个不同的应用程序上花费更多的时间，帮助网络引导创建不同的实用程序。与此同时，它对奖励设置上限，以防止用户通过人为地让应用程序全天打开来利用这一奖励，这不会对公用事业的创造做出有意义的贡献。

The second part of the app usage reward formula looks at a Pioneer’s rolling average of daily time spent across all apps in various time periods. The further back the time period goes, the less it is weighted. In other words, a Pioneer mines more Pi the longer they have been using the Pi apps, but their recent time spent on the apps counts more toward mining than their previous time spent further back in the past. In addition, as a matter of fact, the app usage history takes effect on the current mining reward only if the Pioneer also used Pi apps during their last mining session. This means that there is no passive reward for only the past usage. Once again, the use of logarithmic functions helps moderate the mining boost from app usage to avoid exploitation of the app usage reward. A noteworthy implication here is that Pi chat moderators who have been helping to guide Pioneers and monitor undesirable activities on Pi chats over the last two years will mine the app usage reward at a higher rate when the Mainnet launches.

应用程序使用奖励公式的第二部分着眼于先锋公司在不同时间段内所有应用程序每天花费的滚动平均时间。时间段越往后走，它的权重就越小。换句话说，一个先驱者使用 PI 应用程序的时间越长，他们挖掘的 PI 就越多，但他们最近在这些应用程序上花费的时间比他们过去花在挖掘上的时间更多。此外，事实上，只有当先锋在最后一次挖掘过程中也使用 PI 应用程序时，应用程序的使用历史才会对当前的挖掘奖励生效。这意味着只对过去的使用不会有被动的奖励。同样，对数函数的使用有助于缓和应用程序使用带来的挖掘提振，以避免利用应用程序使用奖励。这里值得注意的一点是，过去两年来一直在帮助引导先锋并监控 PI 聊天上不良活动的 Pi 聊天版主，将在 Mainnet 上线时以更高的速度挖掘应用程序使用奖励。

Node Reward 节点奖励
Like on any blockchain, Nodes are at the heart of the decentralization of Pi. In Pi, instead of relying on centralized institutional nodes, we decided to open up the Nodes to any Pioneer with a computer connected to the internet. Aided by the global trust graph aggregated from individual Pioneer’s Security Circles from the mobile app, these Nodes will run the consensus algorithm to validate transactions and process blocks. Because the Nodes are critical to the decentralization, security, and longevity of the Pi blockchain, Node-operating Pioneers will receive additional mining rewards.

就像在任何区块链上一样，节点是 PI 去中心化的核心。在 PI 中，我们决定向任何拥有连接到互联网的计算机的先锋开放这些节点，而不是依赖于集中化的机构节点。在移动应用程序中从各个先锋安全圈聚合的全局信任图的帮助下，这些节点将运行共识算法来验证交易和处理块。由于节点对 PI 区块链的去中心化、安全性和长寿至关重要，因此节点运营先锋将获得额外的挖掘奖励。

The node reward formula is reprinted here:

N(I) = node_factor • tuning_factor • I, where
Node_factor = Percent_uptime_last_1_days • (Uptime_factor + Port_open_factor + CPU_factor), where
Uptime_factor = (Percent_uptime_last_90_days + 1.5*Percent_uptime_last_360_days(360-90) + 2* Percent_uptime_last_2_years + 3*Percent_uptime_last_10_years),
Port_open_factor = 1 + percent_ports_open_last_90_days + 1.5*percent_ports_open_last_360_days + 2* percent_ports_open_last_2_years + 3*percent_ports_open_last_10_years,
CPU_factor = (1 + avg_CPU_count_last_90_days + 1.5*avg_CPU_count_last_360_days + 2* avg_CPU_count_last_2_years + 3*avg_CPU_count_last_10_years)/4.
Percent_uptime_last_*_days/years is the percentage of the last * time period when the individual Node was live and accessible by the network.
percent_ports_open_last_*_days/years is the percentage of the last * time period when the ports of the individual Node were open for connectivity to the network.
avg_CPU_count_last_*_days/years is the average CPU that the individual Node provided to the network during the last * time period. tuning_factor is a statistical factor that normalizes the node_factor to a number between 0 and 10.
The node reward depends on the uptime factor, port open factor, CPU factor, and the tuning factor. The uptime factor of a Node for a given period of time is the proportion of time the Node is active during that period. For example, a 25% uptime factor yesterday means that the Node was live and accessible for a total of 6 out of 24 hours yesterday. The Pi Node software tracks the time a particular Node is active. Starting in the Open Network phase, only a Node running functionally at a given point in time is considered active. This is a proxy for the reliability of the Node. However, for the historical data relevant to the mining reward, a Node is considered active if the Node app is open and connected to the internet even if it is not running functionally. This exemption for the past performance recognizes that the Community Node operators running the Testnet provided the network with important data and infrastructure to enable multiple iterations of the Node software and Testnet, and that it was not always the fault of the Node operator that their Nodes were inoperative.

节点奖励取决于正常运行时间因素、端口开放因素、CPU 因素和调整因素。节点在给定时间段内的正常运行时间系数是该节点在该时间段内处于活动状态的时间比例。例如，昨天 25%的正常运行时间意味着节点昨天总共有 6 个 24 小时处于活动状态且可访问。PI Node 软件跟踪特定节点处于活动状态的时间。从开放网络阶段开始，只有在给定时间点功能上运行的节点被认为是活动的。这是节点可靠性的代理。然而，对于与挖掘奖励相关的历史数据，如果节点应用程序打开并连接到互联网，则节点被认为是活动的，即使它没有在功能上运行。这项针对过去性能的豁免承认，运行 Testnet 的社区节点运营商向网络提供了重要的数据和基础设施，以实现节点软件和 Testnet 的多次迭代，并且它们的节点不工作并不总是节点运营商的过错。

The port open factor of a Node for a given period of time is the proportion of time the Node’s specific ports are detected to be accessible from the Internet during that period. Pi Nodes use ports 31400 through 31409, enabling other nodes to reach them through these ports and the network IP address. An open-port Node is able to respond to communications initiated by other Nodes, while closed-port Nodes are not able to receive such communications from other Nodes and can only initiate communications. Pi’s consensus protocol relies on Nodes sending a series of messages among each other. Therefore, open-port Nodes are critical to the operation of the Pi blockchain, and thus, worthy of a mining reward boost. In fact, the network aims to have at least 1/8th of the Nodes with open ports, and having an open port is one of the prerequisites for being a Super Node.

节点在给定时间段内的端口开放系数是在该时间段内检测到可以从 Internet 访问该节点的特定端口的时间比例。PI 节点使用端口 31400 到 31409，使其他节点能够通过这些端口和网络 IP 地址访问它们。开放端口节点能够响应由其他节点发起的通信，而封闭端口节点不能接收来自其他节点的此类通信，并且只能发起通信。PI 的一致性协议依赖于节点之间相互发送一系列消息。因此，开放端口节点对 PI 区块链的运行至关重要，因此，值得挖掘奖励提升。事实上，网络的目标是至少有 1/8 的节点具有开放的端口，而拥有开放的端口是成为超级节点的前提条件之一。

The CPU factor of a Node for a given period of time is the average number of CPU cores/threads available on the computer during that period. A higher CPU factor prepares the blockchain for future scalability, for example, the ability to process more transactions per block or more transactions per second. The Pi blockchain is not an energy and resource-intensive blockchain. The network is initially set to operate at one new block of up to 1,000 transactions (T) about every 5 seconds. Thus the network is effectively capable of processing up to about 200 transactions per second (TPS) or ~17M T/day. Should the blockchain get congested in the future, this limit can be increased to 2,000 TPS (~170M T/day) by increasing the block size from 1000 to 10,000 transactions per block. The higher the CPU contributed by Pi Nodes, the more room the network will have to grow and scale further in the future. Furthermore, higher collective CPU from Pi Nodes will allow novel peer-to-peer node-based applications to be built on Pi Network, such as decentralized CPU sharing applications that let computing power-intensive applications run or provide distributed cloud services. Such services will be further rewarding contributing nodes with additional Pi paid by the clients of those services.

节点在给定时间段内的 CPU 系数是该时间段内计算机上可用 CPU 核心/线程的平均数。较高的 CPU 系数使区块链为未来的可扩展性做好准备，例如，每块处理更多事务或每秒处理更多事务的能力。PI 区块链不是能源和资源密集型区块链。该网络最初设置为大约每 5 秒在一个新块上运行，最多可达 1,000 个事务(T)。因此，该网络能够有效地处理高达每秒约 200 笔交易(TPS)或每天约 1700 万 T 的交易。如果区块链在未来变得拥塞，通过将块大小从每个块 1000 个事务增加到 10,000 个事务，可以将此限制提高到 2,000 TPS(约 1.7 亿 T/天)。PI 节点贡献的 CPU 越高，网络将来需要进一步增长和扩展的空间就越大。此外，来自 PI 节点的更高的集合 CPU 将允许在 PI 网络上构建新的基于对等节点的应用，例如分散的 CPU 共享应用，这些应用允许计算能力密集型应用运行或提供分布式云服务。这样的服务将进一步奖励贡献节点由这些服务的客户端支付的额外 PI。

Finally, a tuning factor normalizes the Node reward to a number between 0 and 10. This is meant to make Node rewards comparable to other types of mining rewards that recognize other contributions to Pi Network. During the Enclosed Mainnet phase (as explained in the Roadmap section), the Node reward formula is expected to iterate. For example, the use of logarithmic or root functions may potentially obviate the need for a tuning factor.

最后，调整因子将 Node 奖励归一化为 0 到 10 之间的数字。这是为了使 Node 奖励可以与认可 PI Network 其他贡献的其他类型的挖掘奖励相媲美。在封闭的 Mainnet 阶段(如路线图部分所述)，节点奖励公式预计会迭代。例如，使用对数或根函数可能会潜在地消除对调节因子的需要。

Having reliable Nodes running predictably over a long stretch of time is critical to the health of the blockchain. It is not a one and done contribution. Therefore, the uptime factor, port open factor, and the CPU factor are all calculated over varying time periods, where the value from more recent time periods are more heavily weighted than the time periods of equal lengths from a more distant past. Note, however, that the Node reward is a multiple of the uptime factor of the previous mining session. Hence, a Pioneer will not receive any Node reward in a given mining session if their Node was inactive for the entirety of the immediately preceding calendar day. Similar to the app usage reward, there is no passive reward for only the past contribution as a Node operator. This also means that a low uptime factor in the previous calendar day (even if the Node is active for a part of the day) will substantially reduce the Node reward in a given day despite high past Node contributions.

让可靠的节点在很长一段时间内可预测地运行，对于区块链的健康至关重要。这不是一个已经完成的贡献。因此，正常运行时间因子、端口开放因子和 CPU 因子都是在不同的时间段内计算的，其中较近的时间段的值比较远的过去的相同长度的时间段的值具有更高的权重。但是，请注意，节点奖励是前一个挖掘会话的正常运行时间系数的倍数。因此，如果先锋的节点在前一个日历日的整个时间内处于非活动状态，则该先锋将不会在给定的挖掘会话中获得任何节点奖励。与 APP 使用奖励类似，作为节点运营商，只对过去的贡献没有被动奖励。这也意味着，前一个日历日的低正常运行时间系数(即使节点在一天中的一部分时间处于活动状态)将大大减少给定日期的节点奖励，尽管过去的节点贡献很高。

The Effect of KYC on Mainnet rewards KYC 对主网奖励的影响
There will be a rolling grace period of six calendar months for a Pioneer to complete KYC. Thereafter, the Pioneer loses all the Pi mined outside of the rolling 6-month window and is unable to transfer the lost Pi to the Mainnet. The retention of the mined Pi in the 6-month window continues indefinitely until they pass KYC or the KYC policy changes. Note that this KYC-window mining framework will only begin when the KYC solution is generally available to all eligible Pioneers in the future, and will be announced to the community beforehand. The six-month restriction will not be immediately in place yet when we launch the Mainnet.

先锋队员完成 KYC 课程将有六个月的滚动宽限期。此后，先锋丢失了在滚动 6 个月窗口外开采的所有 PI，并且无法将丢失的 PI 传输到主网。开采的 PI 在 6 个月窗口内的保留将无限期持续，直到它们通过 KYC 或 KYC 政策更改。请注意，此 KYC 窗口挖掘框架仅在 KYC 解决方案将来可供所有符合条件的先锋用户使用时才会开始，并将事先向社区公布。当我们推出 Mainnet 时，6 个月的限制还不会立即到位。

Because of the importance of true humanness in our social network-based mining, only the Pioneers who pass KYC will be able to transfer their Phone balance to the blockchain. Our objective is to have as many true Pioneers as possible pass KYC. As explained further below, the rolling six-month window serves the following important purposes:

由于真正的人性在我们基于社交网络的挖掘中的重要性，只有通过 KYC 的先锋才能将他们的手机余额转移到区块链上。我们的目标是让尽可能多的真正的先锋通过 KYC。如下文进一步解释的那样，滚动六个月窗口有以下重要目的：

strike a balance between giving Pioneers adequate time to pass KYC and creating enough urgency to pass KYC,
prevent unverified Pi beyond the rolling six-month KYC grace period from migrating to the Mainnet, instead freeing it up for mining by other KYC’ed Pioneers within the allocated Pi overall supply limit for Pioneer mining, and
limit KYC spam and abuse (see 30-day delay in KYCing new members below)

在给先锋队足够的时间通过 KYC 和创造足够的紧迫感通过 KYC 之间取得平衡，防止超出滚动六个月 KYC 宽限期的未经验证 PI 迁移到 Mainnet，而是在分配给 Pioneer 采矿的 PI 总供应限制内释放它供其他 KYC 先锋开采，以及。限制 KYC 垃圾邮件和滥用(参见下面的 KYCing 新会员延迟 30 天)

If Pioneers do not pass KYC in time, it delays the Mainnet transfer of their balances and the balances of other Pioneers who have them on their Security Circles and Referral Teams. Without balances on the Mainnet, Pioneers are not able to use payments in Pi apps, thereby undermining the growth of our utility-based ecosystem. A six-month window creates a sense of urgency for Pioneers while giving them adequate time to retrieve their mined Pi. The KYC verification process will generally take into account Pioneers’ likelihood of being real human beings based on Pi’s machine-automated prediction mechanisms run over the last three years. Newly created accounts will not be able to immediately apply for KYC verification, until after 30 days. This helps the network limit the ability of bots and fake accounts to spam and abuse our KYC process and prioritize KYC validation resources for real human Pioneers.

如果先锋队没有及时通过 KYC，就会延误他们的余额和其他先锋队员的余额的主要转移，这些先锋队员在他们的安全圈子和转介团队中拥有这些余额。在主网没有余额的情况下，先锋公司无法在 PI 应用程序中使用支付，从而破坏了我们基于公用事业的生态系统的增长。六个月的窗口为先锋们创造了一种紧迫感，同时给了他们足够的时间来找回他们的地雷 PI。KYC 的验证过程通常会考虑到先锋公司基于过去三年运行的 Pi 的机器自动预测机制而成为真人的可能性。新创建的帐户在 30 天后才能立即申请 KYC 验证。这有助于网络限制机器人和虚假帐户对我们的 KYC 流程进行垃圾邮件和滥用的能力，并为真正的人类先锋确定 KYC 验证资源的优先级。

Finally, the lost Pi of the Pioneers who delay KYC verification beyond six months will not be transferred to the Mainnet and will not be accounted for in the calculation of the systemwide base mining rate (B) beyond the rolling six-month KYC grace period. Pioneers will, therefore, need to claim their Pi in time, or their lost Pi will be reallocated to B for mining in the same year by other verified Pioneers who can make full contributions to the network.

最后，将 KYC 核查推迟六个月以上的先锋公司丢失的 PI 将不会转移到 Mainnet，并且不会计入超过滚动六个月 KYC 宽限期的全系统基本开采率(B)的计算中。因此，开拓者需要及时认领他们的 PI，否则他们丢失的 PI 将在同一年由其他经过验证的先驱者重新分配到 B 进行开采，这些先驱者可以为网络做出全部贡献。

Roadmap 路线图
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.

Pi Network 在我们的技术和生态系统设计以及社区投入对发展的重要性方面都是独一无二的。这种独特性最好是采用深思熟虑的迭代方法，允许社区反馈、测试产品、功能和用户体验，以及里程碑定义的阶段。我们的发展主要有三个阶段：(1)Beta，(2)Testnet，和(3)Mainnet。

Phase 1: Beta 测试版。
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.

2018 年 12 月，我们在 iOS 应用商店公开发布了我们的移动应用，作为最初的先锋登机的 Alpha 原型。2019 年 3 月 14 日，Pi Day，发布了原版 Pi白皮书，标志着 Pi Network 正式上线。在这个阶段，我们的 APP 通过为未来 PI 区块链的增长和安全做出贡献，让先锋挖掘 PI。由于最终目标是启动 Mainnet 并围绕 PI 平台构建一个生态系统，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，这些安全圈合计构建了 Pi 区块链的共识算法所需的信任图，作为回报，Pioneers 获得了挖掘奖励。此外，集中化阶段使网络得以发展，社区得以形成，PI 令牌可访问并广泛分布。此阶段还允许通过在整个开发过程中利用社区输入来迭代许多技术特性和先锋经验。

The following major accomplishments were made during the Beta phase:

在测试阶段取得了以下主要成就：

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.

Pi Network 移动应用程序被列出，并可通过 iOS 应用商店和 Google Playstore 访问。
Pi Network 从 0 发展到超过 350 万名参与先锋。
Pi Network 社区通过 APP、主屏互动和聊天 APP 积极参与该项目。
Pi 网络覆盖全球 233 个国家和地区。

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.

这一阶段于 2020 年 3 月 14 日开始，标志着向去中心化区块链过渡的又一次关键准备-拥有来自世界各地的分布式节点的实时测试网络。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 Testnet。Test-PI 仅用于测试目的，与 Pioneers 在 PI 应用程序上的账户余额无关。PI Testnet 已达到 10,000 多个功能齐全的社区节点和 100,000 多个等待名单上的每日活动节点，并且如后面部分所述，将继续存在以用于 Mainnet 阶段的测试目的。

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.

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将其应用程序部署到 Mainnet 之前开发 PI 应用程序。在 Testnet 阶段，采用了 3 个主要战略：(1)通过 Testnet 节点分散权力；(2)通过移动挖掘的主要 PI 应用程序实现增长；(3)通过 PI 浏览器上的 PI 应用程序平台创建效用。Testnet 与第一阶段的 PI 移动挖掘应用程序并行运行，使分散的社区节点能够上线并为 Mainnet 做好准备。具体地说，Testnet 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 开发人员针对 Pi 区块链测试他们的应用程序。与此同时，Pi 移动挖掘应用程序继续在数百万先锋上使用，建设了社区，并为区块链的安全做出了贡献。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。

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.

在 Testnet 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、头脑风暴和开发工具。
PI 浏览器上引入了 KYC 应用程序的试用版本。
该项目首次在全球范围内进行在线黑客马拉松，来自先锋社区的数千名参与者参加了该项目。
PI Network 已发展到 3000 多万名参与先锋，等待名单上的全功能社区节点从 0 个增加到 10,000 多个，日活跃节点超过 100,000 个。
PI 网络几乎覆盖了世界上所有的国家和地区。

Phase 3: Mainnet 主网 （此刻开始）
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:

2021 年 12 月，Pi 区块链的 Mainnet 将上线。在此期间，Pioneer 余额开始从其电话帐户迁移到 Mainnet。先锋的 KYC 身份验证在其平衡迁移到 Mainnet 之前进行。为了让数百万先驱者有足够的时间成功完成 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，Mainnet 将有两个阶段：

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

首先，防火墙 Mainnet(即封闭式网络)，
然后，打开 Mainnet(即开放网络)。
The Enclosed Network Period封闭式网络时代
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.

这段时间将从 2021 年 12 月开始。封闭的网络期意味着 Mainnet 处于活动状态，但带有防火墙，可防止任何不需要的外部连接。先驱者将能够抽出时间到 KYC，并将他们的 PI 迁移到实时 Mainnet 区块链。任何迁移到 Mainnet 的余额都可以由 Pioneer 选择用于在 PI 应用程序中购买商品和服务，转移到其他 Pioneers，或者被锁定一段时间以获得更高的采矿率。KYC‘ed 开拓者将能够在 PI 网络内的封闭环境中自由地使用他们在主网上的 PI。然而，这段时间将不允许 PI 区块链和其他区块链之间的连接。

Advantages of the Two-Period Approach to Mainnet 两段式主网方式的优势。
There are multiple advantages to having an intermediate enclosed period to ramp up to the fully open Mainnet. This approach allows time for:

有一个中间封闭期来提升到完全开放的 Mainnet 有多种好处。此方法为以下工作留出了时间：

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.

全世界数以百万计的先驱者将通过 KYC，
构建和部署更多 PI 应用程序，并允许创建和使用更多实用程序，
将 Testnet 上部署的 PI 应用过渡到 Mainnet，以及。
在开放网络之前，反复考虑对主网和生态系统的任何修改和调整。

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.

封闭的网络期让数百万先锋有时间进入 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。在接下来的几个月里，我们将继续向更多的先锋推出 KYC 解决方案，并帮助他们完成 KYC。如果我们直接从 Testnet 迁移到 Open Network，这将意味着能够在其他人之前进入 KYC 的先锋将拥有 PI 可用于 PI 平台之外的使用，而仍在等待完成 KYC 的先锋将不会拥有这一特权。世界各地的先锋能够完成 KYC 的速度将取决于每个当地社区为 KYC 验证员提供人群劳动力的速度，以及个别先锋参与 KYC 的速度。

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.

有了封闭的网络期，数百万先锋有时间完成他们的 KYC，并将他们的 PI 转移到 Mainnet。这样，所有愿意并能够在合理的时间内完成 KYC 的先锋都可以立即在 PI 平台之外使用他们的 PI。鉴于 PI 区块链与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，这进一步帮助先锋们专注于过渡到 Mainnet，而不会受到 PI 区块链外部的任何影响。

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.

这段时间还将帮助社区专注于创建公用事业，并在没有任何外部干扰的情况下引导生态系统。与 PI 网络启用基于实用程序的生态系统的愿景一致，这允许应用程序部署在 Mainnet 上并为先锋公司创建实用程序。PI 应用程序将能够从 Testnet 切换到 Mainnet-再到生产模式，以进行真实的 PI 交易。在这个时候，KYC‘ed Pioneers 将能够把他们的 PI 花在 PI 应用程序上，推动公用事业的创建，并在 Open Network 之前引导 PI 生态系统。这种逐步和深思熟虑的开放网络坡道将有助于这些应用程序以及 Pi Network 发现和解决市场和技术中的任何故障。因此，封闭的网络时代与 Pi 的基于效用的生态系统及其迭代哲学的愿景是一致的。

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.

此外，封闭的网络将允许 Mainnet 与生产数据和真实 PI 一起运行，这与 Testnet 不同。在封闭网络期间收集的数据将帮助校准和调整任何配置和公式(如有必要)，以确保一个稳定和成功的开放网络。

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.

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假帐户的过程。Pi Network 的愿景是为所有先锋建立一个包容和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，挖掘率降低了 5 倍。因此，PI 有一人一个账户的严格政策。这需要高度的准确性，才能确定网络中的成员是真正的人，防止个人能够通过创建虚假账户来不公平地囤积 PI。先锋公司的 KYC 结果不仅取决于身份验证，还取决于他们的名字与 PI 账户的匹配情况，以及对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。

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.

正如建网时传达的那样，为了确保真正的人性化，严格禁止虚假的 Pi 账号和脚本化的挖掘。这些帐户将被禁用，并且无法迁移到 Mainnet。在过去的三年里，已经实施了多种技术机制来识别机器人和虚假账户。对于被 Pi 的算法识别为极有可能是假的账户，这些账户的权重取决于这些账户，以证明并非如此。这些被识别的虚假账户要么将被禁用，要么将经历更严格的审查和上诉程序。KYC 插槽的分配将优先考虑那些很有可能是真正的人类持有者的客户。

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.

只有经过身份验证的帐户才能转换到 Mainnet，并且只允许可归因于身份验证帐户的 PI 余额转换到 Mainnet 余额。当先锋和他们的推荐团队和安全圈成员通过时，KYC 将决定先锋是否、何时以及在多大程度上可以转移他们的余额。下面是一个假设的例子，说明 KYC 对先锋的核查如何影响他们迁移到 Mainnet 的余额。

For simplicity, we define different concepts of Pi balances as follows:

为简单起见，我们将 PI 余额的不同概念定义如下：

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

手机余额：PI 手机应用中先锋账号当前显示的 PI 余额。
可转移余额：允许转移到主网的余额，因为先锋及其在推荐团队和安全圈子中的特定关联个人已通过 KYC。
Mainnet Balance：先行者迁移并转移到 Mainnet 的余额

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.

假设个人 A 是一个 PI 帐户的所有者，他想要转移他们的移动余额。先锋 A 只有在其身份得到验证后(即通过 KYC 时)才能将任何移动余额转移到主网。假设这个人在他们的推荐团队中有个人 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 完成了他们的 KYC 验证。

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:

A 是一名通过 KYC 的采矿先锋。
B、C、D、E 在 A 的转诊团队中。
D、E、F、G 在 A 的安全圈内。
A、B、D 和 F 已通过 KYC。
这里，A 的可转让余额是以下三个组成部分的总和：

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.
先锋奖励：根据 A 的先锋身份在所有挖掘会话中挖掘 PI。
贡献者奖励：D 和 F 在所有采矿会话中作为贡献者对 A 的开采率做出的贡献。
大使奖励：当 B 和 D 作为推荐小组成员在与 A 相同的会议期间采矿时，所有采矿会议的采矿奖金。
随着更多先锋 A 的推荐团队和安全圈子成员(即 C、E 和 G)通过 KYC，A 的移动余额的更多部分将变为可转移余额-为 A 迁移到 Mainnet 做好准备，并最终成为 A 的 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, instead freeing it up for mining by other KYC’ed Pioneers within the allocated Pi overall supply limit for Pioneer mining as explained in the Pi Supply section.

在封闭的 Mainnet 期间，任何未成为可转移余额的 Mobile 余额将保留在 Mobile Mining 应用程序中，直到推荐团队和安全圈子中的相关先锋通过 KYC 并相应的金额可转移到 Mainnet 为止。在先锋 A 的上述示例中，C、E 和 G 的余额贡献将在挖掘应用程序中保持为 A 的 Mobile Balance，等待它们通过 KYC，以便此类余额可转移。如果这些关联帐户从未通过 KYC，则归因于这些非 KYC 帐户的余额将在某个特定日期到期，该日期将允许整个网络有足够的时间访问 KYC。由于缺乏 KYC 而导致的无人认领的余额将被丢弃，根本不会转移到 Mainnet，而是释放出来，供其他 KYC‘ed Pioneers 在分配的 Pioneer 采矿总供应限额内开采，如 PI 供应部分所述。

Restrictions in the Enclosed Network封闭网络中的限制。
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:

虽然 PI 应用程序和先锋之间的交易以及 PI 网络内的先锋到先锋交易是允许的，但封闭的网络将有如下所列的限制。在此阶段，这些限制有助于加强网络的封闭性：

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.

PI 和其他区块链或密码交换之间将无法连接。
主网只能通过 PI 浏览器上的 PI Wallet 和 PI 应用程序访问。
互联网上的任何计算机都可以访问 Mainnet 区块链，但只能通过防火墙来执行上述规则。
Mainnet 上将只有 Core Team 节点，以确保防火墙始终到位。

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.

封闭的网络将支持 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‘ed Pioneers 将能够使用 PI 钱包进行 PI 交易。先锋们还可以在 PI 浏览器上的 PI 应用程序中使用 PI，该浏览器可以通过 PI Apps SDK 和 PI Block Chain API 访问 Mainnet。在封闭网络期间，PI 浏览器上的 APP 只能使用防火墙白名单中的 PI 区块链 API 与 Mainnet 进行交互。

The following uses of Pioneer-to-Pioneer, Pioneer-to-App, and App-to-Pioneer transactions will be allowed:

先锋到先锋、先锋到应用和应用到先锋交易的以下用途将被允许：

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

通过 PI Apps 实现商品和服务的 PI 交换。
商品和服务的先行者之间的 PI 转移。

The following uses will be prohibited:

以下用途将被禁止：

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

将 PI 兑换成纸币。
PI 与其他加密货币的兑换。
为未来承诺的法定货币或其他加密货币转移 PI

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.

我们将通过向 Mainnet 添加防火墙以及在此过渡期间独占运行 Mainnet 节点来实施上述限制。在封闭的网络期内，社区节点将继续在 Testnet 上运行。我们将继续对节点实施接口和其他更改，为开放网络时期做准备，届时社区节点将能够在 Mainnet 上运行。进入下一个时期，网络封闭的限制将会放宽--开放网络。

The Open Network Period开放网络时代
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.

根据封闭的网络经济的成熟程度和 KYC 的进展，这段时间可能从 Pi Day(2022 年 3 月 14 日)、Pi2 Day(2022 年 6 月 28 日)或更晚开始。开放网络期意味着封闭的网络期内的防火墙将被移除，允许任何外部连接，例如连接到其他网络、钱包和任何想要连接到 Pi Mainnet 的人。API 调用将不会被防火墙保护，并且 Pioneers 将能够运行他们自己的 PI 节点和 API 服务。先驱者将与其他区块链连接。社区节点也可以运行 Mainnet。
