PAI AMA 问题

Project PAI 项目的 PoUW 开源代码库 https://github.com/projectpai/pouw-main-iteration 已有8个月未提交相关代码了。这项工作停滞了吗?还是团队有自己的公布计划?如果是,内容是什么,什么时候可以公开?

答:如您所知,PAI区块链在6个月前(2020年10月6日在Block Height 154,550处)经历了一次关键性的分叉。这项艰苦的工作启动了所谓的PoW / PoS混合共识机制,使PAI币挖矿首次可公开访问,并引入了一种新的验证形式:质押。在此期间以及几个月之前,实际上,整个开发团队一直(并将继续)专注于Hybrid Hard fork的持续成功,从而暂时中止了有用工作证明(PoUW)的进展。混合共识是PAI Coin协议的基础,该协议要求在其之上构建其他功能(如PoUW)之前,它必须完全稳定且完整。

尽管如此,该团队正在积极探索PoUW下一阶段工作的可能性。迄今为止,PoUW本质上一直是完全实验性的,并在受控环境中进行研究。因此,下一步,团队可能希望通过将PoUW应用于现实世界的用例来以更易于访问的方式展示PoUW。一种可能性是启动一个Alpha版本的交互式控制台,该控制台使用户可以试验该协议并更好地理解PoUW可能产生的影响。

无论如何,我们将随时通知社区进一步的发展。请注意,我们感谢您一直以来的关注,并欢迎您提供反馈。毫无疑问,PoUW是一个非常激动人心的创新项目,具有巨大的潜力。

近些年来,NFT正在发展。您认为今年将是NFT达到顶峰的一年吗?同时,PAI区块链基于BTC分叉,而NFT基于以太坊的ERC721和ERC1155。PAI计划进入市场的计划是什么?

答:毫无疑问,NFT现在是加密领域中非常热门的话题。至于今年是否会达到顶峰,这是每个人的猜测,但是NFT提供的大量实际应用程序对它的未来来说是个好兆头。

尽管ERC721和ERC1155标准是在以太坊生态系统中如何构建NFT的绝佳示例,但NFT并非仅为以太坊专有。PAI具有自己的NFT风格 – 遵循PDP2数据存储机制。Catenaart.com是如何使用PDP2在PAI区块链上存储NFT的一个示例。

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。

PAI 开发进度

下面是Project PAI核心团队的开发工作简报:

● [PAI区块链核心]解决2.3.0版本候选版本期间发现的问题的解决方案正在进行中。

● 此更新的主要目标是减少由于对新开采的区块缺少投票而导致链失速的可能性。团队针对此问题的解决方案包括两个基本变化:

○ 投票交易的优先级高于标准交易,以使投票不会在内存池中被”埋葬”。

○ 如果给定的新开采的候选区块仍在等待投票,矿工可以继续挖掘平行的提示(即,包含可能准备立即进行投票的一组不同的权益凭证的等效区块),但对其他同伴(节点)有利)在网络中必须意识到它们。为此,进行了更新以确保也优先处理并行链提示的广播。

● 在进行了上述投票交易和链提示优先级更新之后,发现:

○ 新加入的同行可能会在IBD(初始区块链下载)期间禁止现有的同行。

■ 为了解决此问题,仅当两个对等方处于相同或相似的区块高度时,才将投票交易和链条提示发送给对等方。

○ 重复传输投票交易也可能导致同行禁止。

■ 为了解决这个问题,实施了使用存货清单过滤器的按人对票的过滤。

● 一旦所有测试通过,将公开发布2.3.0版本。我们非常希望向您提供它。

● [Catena NFT市场]

○ 来自REST调用和来自Websockets的同步消息

○ 无限滚动适用于线程的消息

○ 解决了以下问题:如果消息所处的布局中滚动条的条位于滚动条槽的底部(该布局代表大多数现代聊天应用程序),则滚动不起作用;事实证明,这是Firefox的一个错误,该错误已于去年9月得到解决(github.com/philipwalton/flexbugs/issues/108)

○ 移动优化以”适合”同一屏幕中的线程和消息

○ 在接下来的一周中,将此补丁和其他错误修复程序集成到Catena Art中

PAI AMA Questions

The project’s pouw open source repository https://github.com/projectpai/pouw-main-iteration has not submitted relevant code for 8 months. Is this work stalled? Or is there any public development success related to the team? If so, what are the contents and when can they be made public?

A: As you may know, the PAI Coin blockchain underwent a critical hard fork nearly 6 months ago (October 6, 2020 at Block Height 154,550). This hard fork launched the so-called Hybrid PoW/PoS Consensus Mechanism, making PAI Coin mining publicly accessible for the first time, and introducing a new additional form of validation: staking. During this time, and for several months prior, virtually the entire development team had been (and continues to be) focused on the ongoing success of the Hybrid hard fork, thereby temporarily pausing progress on Proof of Useful Work (PoUW). Hybrid Consensus is the foundation of the PAI Coin protocol, which necessitates that it is fully stable and complete before building additional features, like PoUW, on top of it.

Nonetheless, the team is actively exploring possibilities for the next phase of work for PoUW. To date, PoUW has been totally experimental in nature and worked on in controlled settings. Thus, as a next step, the team may want to present PoUW in a more accessible way by applying it to real-world use cases. One possibility is to launch an alpha-version interactive console that allows users to experiment with the protocol and better understand the impact that PoUW can have.

In any case, we will keep the community apprised of further developments. Please note that we thank you for your continuing interest and welcome your feedback. PoUW is undoubtedly a very exciting and innovative project that has enormous potential.

NFT is trending these days. Do you think this year will be a year when NFT will reach its height? At the same time, PAI is forking BTC, and NFT is based on Ethereum’s ERC721 and ERC1155. What’s Project PAI’s plan to enter the market?

A: Undoubtedly NFT is a very hot topic in the crypto space right now. As for whether or not this is the year that it will peak—that’s anyone’s guess, but the vast array of real-world applications that NFT offers certainly seem to bode well for its future.

NFTs are not exclusive to Ethereum, although the ERC721 and ERC1155 standards are great examples of how a NFT can be built in the Ethereum ecosystem. PAI has its own of NFT — following the PDP2 data storage mechanism. Catenaart.com is an example of how PDP2 can be used to store NFTs on the PAI Blockchain.

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:

● [PAI Coin Core] Resolution of issues uncovered during testing of the release candidate for 2.3.0 is ongoing.

● Recall that the primary goal of this update is to reduce the possibility of chain stalls due to a lack of votes for newly mined blocks. The team’s solution to this comprises two fundamental changes:

○ Vote transactions are prioritized over standard transactions so that votes don’t get “buried” in the mempool.

○ If a given newly mined candidate block is still waiting on votes, miners can proceed to mine parallel tips (i.e., equivalent blocks containing a different set of stake vouchers that may be ready to vote immediately), but to be beneficial, other peers (nodes) in the network must be aware of them. To this end, updates were made to ensure that the broadcasting of parallel chain tips is also prioritized.

● Following the aforementioned vote transaction and chain tip prioritization updates, it has been found that:

○ Newly joined peers may ban existing peers during IBD (Initial Blockchain Download).

■ To address this issue, vote transactions and chain tips are only sent to peers once the two peers are at the same or similar block height.

○ Repetitive transmission of vote transactions may also result in peer banning.

■ To address this, per-peer filtration of votes using an inventory bloom filter was implemented.

● The 2.3.0 release will be made public once all tests pass. We are eager to make it available to you.

● [Catena NFT Marketplace]

○ Synchronized messages coming from REST calls and those coming from Websockets

○ Infinite scrolling working for the messages of a thread

○ Resolving an issue where scrolling didn’t work if the messages were in a layout where the bar of the scrollbar was at the bottom of the scrollbar’s trough (a layout which represents most modern chat apps); it turns out this was a bug in Firefox that was resolved last September (github.com/philipwalton/flexbugs/issues/108)

○ Mobile optimizations to “fit” the threads and messages in the same screen

○ Integrating this patch and other bug fixes into Catena Art in the coming week
