Project PAI 去中心化经济的演变

任何新产品的成功都取决于许多因素和各个方面。成功是分阶段进行的，并且有重叠的阶段，这需要并且取决于利益相关者在每个阶段进行协作。根据协作的结构，其价值主张和法规要求，遇到和预测到的挑战可能都会有所不同。

当应用于PAI区块链时，最初的核心开发人员开始着手在具有比特币协议线路上为网络协议的开源代码贡献代码，并具有一些与众不同的功能，例如分布式存储。该代码是完全开源的，任何开发人员都可以快速使用它，也可以为开源做出贡献。网络本身也完全是去中心化的，这样任何人都可以贡献计算资源来支持网络。开源的挖矿共识也完成了设计和部署，这可以避免对网络的恶意攻击。作为开放源代码协议的一部分，Project PAI提供的API允许任何开发人员从任何应用程序进行接口。开发人员维护开源代码，并为新开发人员提供支持。

完全去中心化带来了诸如缺乏任何中央管理机构或领导层的挑战。因此，用户、开发人员和支持者的社区都有责任将其认为适合改进协议的事情向前推进。社区是网络协议成功的关键。实际上，有人可能会从”梅特卡夫定律”中发现，开源、去中心化网络的价值取决于其背后的社区的作用。

开源协议类似于操作系统（OS）。它的采用将取决于用户如何与之交互。通常使用应用程序层（通常称为应用程序，可以转换为Web和本地移动应用程序）来完成此操作。优秀的开发人员不仅应考虑网络协议的价值主张，还应考虑其背后的支持社区，其KPI，并提出不仅具有实际意义而且还具有可持续业务和收益模式的可持续发展的应用程序。

作为应用程序的一部分，作为操作系统的区块链仍处于市场采用的早期阶段。它带来了一些挑战，例如高昂的交易费用，缺乏易于使用的用户界面，数字资产的安全性以及使用与底层区块链相关的数字代币的原因。但是，每一项挑战也带来了早期采用者的机会。

开发人员应考虑使用PAI协议的一些原因包括但不限于：

●PAI协议已完全去中心化

●所有代码以及与网络协议交互的API均在GitHub上可用且开源

●有一个由不同国家/地区的用户组成的社区，它们充当适当应用程序的早期采用者并提供营销支持，从而降低了应用程序开发人员为其应用程序吸引用户的成本

●它具有去中心化和分布式的存储协议

●它具有用于识别目的和单点登录帐户管理的开源KYC系统

●可选择性地用于交易的数字令牌

鼓励开发人员利用区块链领域当前的市场趋势，开发应用程序并在整个开发过程中与社区进行交互，扩展到最小可用产品（MVP）推出及以后。

即将到来的利用PAI协议的应用程序的示例包括基于NFT的艺术市场，该市场利用了网络协议的所有上述功能。该应用程序执行以下操作：

●艺术家可以使用单点登录（SSO）创建个人资料，并列出要出售的艺术品（数字形式和实物形式）

●所有上传的艺术品都存储在分布式分散式存储系统中

●收藏家/买家可以使用SSO创建其个人资料并浏览列出的艺术品

●收集者和购买者可以使用安全的消息传递系统进行交互

●收藏家可以使用数字令牌和/或法定货币为艺术品付款

Project PAI 鼓励开发人员在paiforum.com上与社区讨论有关新应用的想法。活跃的社区期待收到更多的项目并也使用它们。

○ 我们还实现了特定地址的视图界面，其中包括了涉及到该地址的所有历史交易的列表（加载时请您耐心等待）。例如：

https://pouw-portal-alpha.projectpai.com/address/PvkpR1oaYCF5WVztnjEzXDpz9JrzLfJfDs

○ 即将开始的PoUW项目工程:

■ 导航栏

■ 单个块视图

■ 挖出的所有区块列表

■ 用户教育与推广页面

■ 与 PoUW 后端的集成

● [PAI Coin Core] PAI Coin v3.0.0 的测试网试运行正在进行中。

○ 在通过一小组私有节点推进测试网区块链方面取得了一些显着进展。如果这仍然没有问题，团队希望在本周时或下周初在测试网上测试 v3.0.0 硬分叉。

○ 由于重新启动测试网的问题，这个过程比预期的要长，测试网在 2020 年 10 月 11 日成功混合共识硬分叉后不久停止了更新。

○ 一旦确认测试网功能正常，将公布主网上 PAI Coin 3.0 硬分叉的目标区块高度。

○ PAI Coin 3.0 成功升级后，团队将恢复通过 PAI Miner 进行 PCP 挖矿的功能。同时, PCP 发的奖励预期会进一步的增加。

○ PAI 的核心贡献者们在测试网无法及时恢复的情况下也同时在研究其他方案测试并为 PAI Coin 3.0 的硬分叉定下区块高度。

● [projectpai.com] projectpai.com 的网站正在重新更新新页面。新网站将更准确地反映 Project PAI 的整体项目状态，包括其新的进展及方向! 请注意，由于团队工程资源有限以及 PAI Coin v3.0 和 PoUW 的优先权，新页面预计是到 2021 年 8 月至 9 月推出。

●[catenaart.com] 团队持续跟进 Catena NFT产品的开发和升级工作。目前由于团队工程资源有限以及 PAI 区块链 v3.0 和 PoUW 项目的优先权， Catena 项目的升级有所延后。感谢PAI社区的支持和耐心！

The Evolution of a Decentralized Economy

The success of any new creation is a function of many factors and moving parts. Success happens in stages and has overlapping phases, which requires and depends upon the stakeholders to collaborate at every stage. The challenges encountered and forecasted can vary depending upon the structure of the creation, its value proposition and regulation.

As applied to the PAI blockchain, the initial core developers set about contributing code to open source for a network protocol on the lines of bitcoin protocol with some differentiating features such as decentralized storage. The code is completely open source and any developer can utilize it quickly and also contribute back to open source as well. The network by itself is also completely decentralized such that any person is able to contribute computational resources in order to support the network. The open source mining consensus has also been designed in a way to avoid malicious attacks on the network. The APIs available as part of the open source protocol allows any developer to interface from any applications. The developers maintain the open source code and provide support to new developers as well.

Complete decentralization brings challenges such as a lack of any central governing body or leadership. Thus the onus is on the community of users, developers and supporters to move things forward as they deem fit for the improvement of the protocol. The community holds the key to the success of the network protocol. In fact, one could potentially argue and imply from Metcalfe’s law that the value of an open source, decentralized network is a function of the role of the community behind it.

An open source protocol is analogous to an operating system (OS). Its adoption will depend upon how users interact with it. This is typically done using application layers (commonly known as apps, which can translate to both web and native mobile apps). A good developer should not only consider the value proposition of the network protocol but also the supporting community behind it, their KPI’s, and come up with apps which not just make practical sense but are also sustainable on its own with a viable business and revenue model.

Blockchain as an OS is still in a very early stage of market adoption as part as applications are concerned. It presents several challenges such as high transaction fees, lack of easy to use user interfaces, safety of digital assets and the reason to use digital tokens associated with the underlying blockchain. But every challenge also brings with it early adopter opportunities.

Some reasons that developers should consider using the PAI protocol include but are not limited to:

● The PAI Protocol is fully decentralized

● All code is available and open-sourced on GitHub, along with APIs for interacting with the network protocol

● A community of users in different countries which act as the early adopter for an appropriate app and provides marketing support, thus driving down the cost of user acquisition for the app developer for their app

● It has a decentralized and distributed storage protocol

● It has an open source KYC system for identification purposes and single sign-on account management

● Digital tokens which can optionally be utilized for transactions

Developers are encouraged to take advantage of current market trends in the blockchain space and create apps and interact with the community across the development process, extending to MVP launch and beyond.

Examples of upcoming applications utilizing the PAI protocol include an NFT-based art marketplace which utilizes all the above listed features of the network protocol. This application does the following:

● Artists can create profiles using single-sign on (SSO) and list their art pieces (in both digital and physical form) for sale

● All uploaded pieces of art are stored on a distributed and decentralized storage system

● Collectors/Buyers can create their profiles using SSO and browse through listed artwork

● Collectors and Buyers can interact with each other using a secure messaging system

● Collectors can pay for art using digital tokens and/or fiat currency

Developers are encouraged to discuss on paiforum.com with the community about their ideas for new apps. The active community is looking forward to receiving more projects and using them as well.

PAI Weekly Updates

Here’s a snapshot of development work the team has been focused on:

● [PoUW Portal] Several updates have been made to the portal, which is available for your viewing here:

https://pouw-portal-alpha.projectpai.com

○ Implemented transaction-specific views for each type of transaction, examples:

■ Coinbase (i.e., Mining Block Reward):

https://pouw-portal-alpha.projectpai.com/transaction/96d0b71ae29634613fa5007cf09b83a6748d3002c5132541ad38fcb85b8f027f

■ Standard:

https://pouw-portal-alpha.projectpai.com/transaction/1ac8fd78d0e528914504fbf65901d22f07a25a8d87f0f0631590a90ddfca69be

■ Vote:

https://pouw-portal-alpha.projectpai.com/transaction/2d7c531bf33baba0f6e7a8f6e2ed212d1f320676c1b832be68465e61b57f553d

■ Stake Voucher Purchase:

https://pouw-portal-alpha.projectpai.com/transaction/5f9147bba8fec25d424176057bff4720b9ca943b36f1d3f8941206e1f6e9957c

■ Stake Voucher Revocation:

https://pouw-portal-alpha.projectpai.com/transaction/93676488150fdc155bcd81fef506185c2f3d0c42e1ce6ec61a5a365f2a6cdf91

○ Implemented address-specific views that include a list of all transactions that involved the address (please be patient while it loads). example:

https://pouw-portal-alpha.projectpai.com/address/PvkpR1oaYCF5WVztnjEzXDpz9JrzLfJfDs

○ Upcoming work (in no particular order):

■ Navigation bar

■ Individual block views

■ List of all blocks mined

■ Educational and promotional pages

■ Integration with PoUW backend

● [PAI Coin Core] The testnet dry run of PAI Coin v3.0.0 is ongoing.

○ Some notable progress has been made in advancing the testnet blockchain across a small set of private nodes. If this persists without issue, we hope to test the v3.0.0 hard fork on testnet later this week or early next.

○ This process has been taking longer than expected due to issues with relaunching testnet which had been paused since shortly after the successful hybrid consensus hard fork on October 11, 2020.

○ Once proper testnet functionality is confirmed, a target block height for the hard fork to PAI Coin 3.0 on mainnet will be announced.

○ After successfully upgrading the network to PAI Coin 3.0, PCP mining via PAI Miner will be restored and PCP stake rewards are expected to further increase.

○ PAI core contributors are also investigating other alternatives to test and set a date for the hard fork to PAI Coin 3.0 in the event that testnet functionality could not be restored in a satisfactorily timely fashion.

● [projectpai.com] A website redesign is underway. The revamped site will more accurately reflect the current state of Project PAI including its new and exciting directions! Please note, however, that due to resource limitations and the more important priorities of PAI Coin v3.0 and PoUW, the launch of the new site will likely not occur until August-September 2021.

● [catenaart.com] The team is currently working on upgrading Catena. Due to resource limitations and the more important priorities of PAI Coin v3.0 and PoUW, this has been taking longer than expected. Thank you for your patience!
