In the earliest days of Bitcoin and first-generation cryptocurrencies, anyone could mine coins using any basic computing setup. Until around 2013, all you needed was a standard GPU. However, as the value of Bitcoin rose and more miners entered the space, cryptocurrency mining became ever more competitive, to the point where it now requires specialist hardware dedicated to the task of mining.

在比特币和第一代加密货币的早期，任何人都可以使用任何基本的计算设置来挖掘硬币。直到2013年左右，你所需要的只是一个标准的GPU。（咨询加VX:15371392617）然而，随着比特币价值的上升和越来越多的矿工进入这个领域，加密货币开采变得越来越有竞争力，以至于现在需要专门的硬件来完成开采任务。

These days, crypto mining is no longer accessible to the average person. Bitmain has a de facto monopoly over the supply of mining equipment, and just six mining pools dominate the majority of BTC mining activity, with the top three controlling 50%. Mining activity is often so concentrated that a localized power outage in China can precipitate a market crash.

如今，普通人已无法使用加密挖掘。Bitmain事实上垄断了采矿设备的供应，只有6个采矿池主导了BTC的大部分采矿活动，前三名控制了50%。矿业活动往往如此集中，以至于中国的局部停电可能导致市场崩溃

As cryptocurrency becomes more institutionalized, mining Bitcoin and other major altcoins will only continue to centralize. However, making cryptocurrencies, and mining in particular, accessible to the masses is the aim of Pi, a blockchain initiative spearheaded by two founders with a Stanford Ph.D. in Computer Science and Social Sciences.

随着加密货币越来越制度化，开采比特币和其他主要的比特币只会继续集中。然而，使加密货币，特别是采矿，为大众所用，是Pi的目标，Pi是一个区块链计划，由两位拥有斯坦福博士学位的创始人发起。计算机科学和社会科学。

What is Pi?

Pi was conceived with the vision of re-democratizing access to cryptocurrencies and making them accessible for anyone to mine with equipment that’s easily available – a smartphone.

什么是圆周率？

Pi的构想是为了使加密货币的使用重新民主化，并使任何人都可以使用易于获得的设备——智能手机——开采加密货币。

The project achieves this by using a variation of the Federated Byzantine Agreement (FBA), devised by the scientists behind the Stellar blockchain. Whereas proof of work and the many variations on proof of stake rely on the idea of one miner or validator becoming the “leader” by proposing a block for consensus, the FBA operates using a different approach.

该项目通过使用联邦拜占庭协议（FBA）的变体来实现这一点，联邦拜占庭协议是由恒星区块链背后的科学家们设计的。然而，工作证明和许多不同的股权证明依赖于一个矿工或验证者成为“领导者”的想法，提出一个块共识，FBA使用不同的方法运作。

Rather than nominating a leader, this consensus model depends on nodes reaching consensus over a particular block through a series of voting through exchanging messages. A? widely known type of algorithm that uses such a mechanism to reach consensus is Byzantine Fault Tolerance (BFT), which is implemented in various blockchains, including Ripple, Hyperledger Fabric, and Zilliqa. However, one criticism of BFT consensus models in general is that they have a point of centralization because the system creator centrally determines the set of nodes participating in the voting quorum at genesis.

这种共识模型不需要指定一个领导者，而是依赖于节点通过交换消息的一系列投票，在特定的区块上达成共识。使用这种机制达成共识的一种广为人知的算法是拜占庭容错（BFT），它在各种区块链中实现，包括Ripple、Hyperledger Fabric和Zilliqa。然而，对BFT共识模型的一个批评是，它们有一个集中点，因为系统创建者在genesis集中决定参与投票仲裁的节点集。

To overcome the centralization risk, Pi uses the additional layer of FBA which allows each node to set their own “quorum slices” in a decentralized manner. This feature enables nodes to determine for themselves whether or not to trust other nodes, rather than relying on a central authority to do so.

为了克服集中化风险，Pi使用了FBA的附加层，允许每个节点以分散的方式设置自己的“仲裁片”。此功能使节点能够自行决定是否信任其他节点，而不是依赖于中央机构。

Because the messaging involved in voting is relatively lightweight, particularly compared to proof of work, Pi’s consensus algorithm consumes very little energy.

由于投票中涉及的消息传递相对较轻，特别是与工作证明相比，Pi的一致性算法消耗的能量很少。

How to Mine Pi

Users can participate in mining Pi by downloading the Pi Network app to their smartphone. Then, they can play up to four roles in the Pi consensus:

如何挖掘圆周率

用户可以通过将Pi网络应用下载到智能手机上参与挖掘Pi。然后，他们最多可以在Pi共识中扮演四个角色：

Pioneers are users of the mobile app who simply validate their presence each time they log in. Their contribution is in making Pi Network widely distributed. Currently, they can send and receive only Test-Pi on Pi Testnet through their Pi wallets.

Contributors are users who provide a list of pioneers they know and trust and maintain this list up to date. Ultimately, contributors are helping to develop the global trust graph needed for Pi’s consensus.

Ambassadors are users who introduce others to the Pi network.

Nodes are pioneers and contributors who also run the Pi node software on a desktop or laptop computer. Pi Nodes perform the heavy lifting of running the consensus algorithm of the blockchain and will use the trust graph aggregated from the trusted pioneers provided by mobile contributors

Participants can play more than one role. Each day, they receive newly minted Pi based on their participation and contribution.

先锋是移动应用程序的用户，他们每次登录时都会验证自己的存在。他们的贡献是使Pi网络广泛分布。目前，他们只能通过Pi钱包在Pi Testnet上发送和接收测试Pi。

贡献者是提供他们认识和信任的先驱列表并保持此列表最新的用户。最终，贡献者正在帮助开发Pi达成共识所需的全球信任图。

大使是向其他人介绍Pi网络的用户。

节点是先驱和贡献者，他们也在台式机或笔记本电脑上运行Pi节点软件。Pi节点执行运行区块链一致性算法的繁重任务，并将使用从移动贡献者提供的可信先驱聚合的信任图

参与者可以扮演多个角色。每天，他们都会根据自己的参与度和贡献获得新铸造的圆周率。

The current value of Pi is stated as zero. The team behind Pi believes that value can be realized through the creation of utilities of the cryptocurrency where people use Pi to transact goods and services at scale globally. These goods and services will ultimately back the value of Pi.

Pi的当前值表示为零。Pi背后的团队相信，价值可以通过创造加密货币的实用工具来实现，人们可以使用Pi在全球范围内进行大规模的商品和服务交易。这些商品和服务最终将支持Pi的价值。

KYC and Privacy

To maintain the integrity of the network, Pi operates a KYC policy. Users must be verified with a copy of their ID to be able to transfer Pi into the Pi Mainnet blockchain. This prevents any abuse of the system by users attempting to operate multiple accounts or run bots, or farms, etc. It also means that Pi is growing to become one of the first and largest verified networks.

KYC和隐私

为了保持网络的完整性，Pi采用KYC策略。用户必须使用其ID的副本进行验证，才能将Pi传输到Pi Mainnet区块链。这可以防止用户试图操作多个帐户或运行机器人程序或农场等滥用系统。这也意味着Pi正在成为第一个和最大的验证网络之一。

Pi Network currently uses a trusted third-party vendor to secure the KYC process and data. The company commits to keeping user data safe per its privacy policy and undertakes not to sell or otherwise abuse user KYC data.

Pi网络目前使用可信的第三方供应商来保护KYC进程和数据。公司承诺根据其隐私政策保护用户数据安全，并承诺不出售或以其他方式滥用用户KYC数据。

Developments and Roadmap

Pi has been in development since 2018. Currently, the project is in testnet mode. The Pi Testnet, a publicly accessible system, has over 10,000 nodes connected with stable liveness, which will make it one of the largest and most powerful distributed networks in the world once its Mainnet launches. To participate in the Pi Testnet, users can download the Pi desktop software Pi Node from their website node.minepi.com? and participate through an existing Pi mobile app account. .

发展和路线图

Pi自2018年开始开发，目前项目处于testnet模式。pitestnet是一个可公开访问的系统，它有超过10000个节点连接在一起，具有稳定的活动性，一旦其主网启动，它将成为世界上最大和最强大的分布式网络之一。要参与Pi测试网，用户可以从其网站Node.minepi.com下载Pi桌面软件Pi节点，并通过现有的Pi移动应用程序帐户参与。

The network will continue to operate in testnet until roughly the end of 2021, after which it will launch on mainnet.

该网络将继续在测试网运行到大约2021年底，之后它将在主网推出。

In the meantime, the Pi team is also building its Pi Utilities platform to support the Pi ecosystem, where the whole network can contribute and build the path to generating value. The project recently released its latest updates and plan for its Utilities platform for Q2 of 2021, including platform integration with the Pi Testnet that allows third-party Pi apps to request transactions of users’ Pi wallets and make transactions on the testnet. When Pi’s mainnet goes live, these features will allow Pi users to spend their Pi tokens in Pi-based apps. The Pi Browser, which is another mobile application of Pi Network that launched in March 2021,? will also become integrated with the Utilities Platform. From the developer’s standpoint, the team is working on a new developer portal and a standardized environment to build and deploy ecosystem apps.

与此同时，Pi团队也在构建其Pi公用事业平台，以支持Pi生态系统，在那里整个网络可以贡献和建立产生价值的路径。该项目最近发布了其最新更新，并计划在2021年第二季度推出其公用事业平台，包括与Pi测试网的平台集成，允许第三方Pi应用请求用户的Pi钱包交易，并在测试网进行交易。当Pi的主网上线时，这些功能将允许Pi用户在基于Pi的应用中使用他们的Pi代币。Pi浏览器是Pi Network于2021年3月推出的另一个移动应用程序，它也将与公用事业平台集成。（咨询加VX:15371392617）从开发人员的角度来看，该团队正在开发一个新的开发人员门户和一个用于构建和部署生态系统应用程序的标准化环境。

It’s fair to say that Pi is adopting a “slow and steady” approach to launching on the mainnet, which goes against the grain when compared to many other platforms. The reason for this is that the project is using the Beta launch to iterate and improve on the protocol together with community members and developers while developing its ecosystem and community around the currency to bootstrap an economy. The idea is that by the time the mainnet launches, there will already be an established network happy with the product and ecosystem of apps for use. Pi already operates in 238 countries and 52 languages.

可以说，Pi在主网上采用了一种“缓慢而稳定”的方式，与许多其他平台相比，这是背道而驰的。这样做的原因是，该项目正在利用Beta发布与社区成员和开发者一起迭代和改进协议，同时围绕货币开发其生态系统和社区，以引导经济。他们的想法是，到主网发布时，已经有一个成熟的网络对产品和应用生态系统感到满意。Pi已经在238个国家和52种语言开展业务。

Team

Pi was founded by Dr. Nicolas Kokkalis and Dr. Chengdiao Fan. Dr. Kokkalis holds a Ph.D. from Stanford and was the instructor of Stanford’s first class on decentralized applications, and co-teaches the Beyond Bitcoin class at Stanford once a year. In the course of teaching his dapps class, he came to realize the difficulty of making blockchain technology available to everyday people.

团队

Pi由Nicolas Kokkalis博士和樊承钓博士创立。Kokkalis博士拥有斯坦福大学的博士学位，是斯坦福大学关于去中心化应用的第一节课的讲师，每年在斯坦福大学共同教授一次超越比特币课程。在dapps的教学过程中，他意识到让区块链技术普及到日常生活中的困难。

Dr. Fan holds a Ph.D. in Computational Anthropology from Stanford. Her research has focused on human-computer interactions and social computing – how we can use technology to positively impact human behavior and societies.

他拥有斯坦福大学计算人类学博士学位。她的研究重点是人机交互和社会计算——我们如何利用技术积极影响人类行为和社会。

In total, the Pi team comprises 14 people working around the globe.

Pi团队共有14人，分布在全球各地。

Conclusion

The barriers to entry for mining most major cryptocurrencies are currently so high that most participants are excluded. Mining Pi on a smartphone is a simple and easy way to watch cryptocurrency rewards accrue on a daily basis.

结论

目前，挖掘大多数主要加密货币的进入门槛很高，大多数参与者都被排除在外。在智能手机上挖掘Pi是一种简单易行的方法，可以观察加密货币奖励每天积累。

However, the value of those rewards requires Pi to gain the traction and usage of the network effect. Only once enough people participate and are willing to transact goods and services in Pi,? will the rewards gain any real-world value. In that sense, the success of Pi depends on its ability to reach enough people and enough utilities.

然而，这些奖励的价值需要Pi获得网络效应的牵引力和使用。只有当足够多的人参与并愿意在Pi中交易商品和服务时，奖励才会获得现实世界中的价值。从这个意义上说，Pi的成功取决于它接触到足够多的人和足够多的效用的能力。

If the project can meet this challenge, Pi has every chance of being a success when it launches on the mainnet.

如果该项目能够迎接这一挑战，当它在主网上发布时，就有机会获得成功。
