再次欢迎@Sam，我们正式开始吧~

Welcome again @Sam ，Okay, let's start.

问题1：

可以从您的角度，先给我们社区的小伙伴简单介绍一下 Umbrella 这个项目吗？它的愿景和使命是什么？

Question 1:

Can you have a brief introduction about Umbrella? What is its vision and mission?

Umbrella Network has two primary missions. First, Umbrella wants to decentralize ownership of the oracle we’re building. We believe an oracle is a critical piece of infrastructure for decentralized applications. And so, we think it’s crucial that ownership and control is not held by a single person or small group of executives. And that’s why we’re determined to put the power into the hands of our community.

The second goal is to drive the cost of on chain data to as close to $0.00 as possible. We believe only once data is incredibly cheap will we have a thriving decentralized world. With our technology, we believe we have a massive cost advantage over the competition. And so we will make the most commonly used data available for free. And to support continued innovation by startups and smaller enterprises, we’ll offer free data tier.

Umbrella Network 有两个主要任务。 首先，Umbrella希望将我们正在建立的Oracle的治理权下放。 我们认为，oracle是分散应用程序的关键基础架构。 因此，我们认为至关重要的是，所有权和控制权不能由一个人或一小撮高管人员掌握。 这就是为什么我们决心将权力移交给社区的原因。

第二个目标是使链上数据的成本尽可能接近$ 0.00。 我们相信，只有数据便宜到令人难以置信的程度，我们才能拥有蓬勃发展的去中心化世界。 凭借我们的技术，我们相信我们在竞争中拥有巨大的成本优势。 因此，我们将免费提供最常用的数据。 为了支持初创企业和小型企业的持续创新，我们将提供免费的数据层。

问题2:

请问为什么会选择波卡？

Question 2:

Why did you choose Polkadot?

I’d like to talk about why we chose both Polkastarter for our IDO and have plans to build on Polkadot. Because I think they are very closely related.

The Polkastarter community has the potential to rival those of YEarn and other leaders in the space. The community of crypto enthusiasts are unparalleled if you ask me. The quality of the projects that are launching here is superior to any other launchpad we’ve seen in the market. Just look at the list: from YOP Finance, Bridge Mutual, MahaDAO, etc, etc. These projects are the future of DeFi. So how could I turn down an opportunity to join and sit in a room with them.

And of course, the focus on Polkadot. While we’re built on Ethereum currently, we have every intention of moving over to Polkadot in short order. The advantages there are just too obvious. From the low transaction costs to the interoperability and the ability to launch and message across parachains. These are all incredible enablers of blockchain applications.

And I believe the Polkastarter community and its ecosystem of projects are really what’s going to drive Polkadot to realize its full potential. And Umbrella Network looks forward to providing the underlying oracle infrastructure for this amazing group.

想谈一谈为什么我们既选择Polkastarter作为IDO，又计划在Polkadot上进行开发。因为我认为它们之间息息相关。

Polkastarter社区具有与YEarn和该领域其他领头羊相媲美的潜力。在这里启动的项目的质量优于我们在市场上看到的任何其他项目。只需看一下清单：YOP Finance，Bridge Mutual，MahaDAO等，这些项目就是DeFi的未来。因此，我怎么能拒绝与他们一起坐在一个房间里的机会。

当然，重点放在Polkadot。虽然我们目前是在Ethereum上创建，但我们有意在短期内转移到Polkadot。Polkadot的优势太明显了，从低廉的交易成本到互操作性以及跨平行链启动和发送消息的能力，这些都是区块链应用不可思议的促成因素。

我相信Polkastarter社区及其项目生态系统会促使Polkadot发挥其全部潜力。而且，Umbrella Network希望为这个令人惊讶的团队提供底层的Oracle基础架构。

问题3：

可以介绍一下你们团队背景和故事吗？

Question 3:

Can you tell us the background and story of your team?

For the past 10 years, the senior team at Umbrella and I focused on building highly performant and scalable products, primarily in the digital advertising industry. I served as the Co-Founder and COO of Gimbal, a buy side platform that recently acquired TrueX from Disney.

Many of us were frustrated by the fraud, corruption and general lack of transparency in digital advertising. In 2017, a few of us discovered Ethereum. We were totally blown away. We thought it’d be the perfect tool to solve our frustrations with digital advertising. And so we decided to start Lucidity to provide a transparent, scalable marketing analytics solution to advertisers. Lucidity currently works with some leading traditional brands like Toyota, Hyundai, KFC and GroupM.

We noticed that the oracle market was also undergoing similar issues to what we experienced in digital advertising, mainly that oracles were slow and inefficient, writing one piece of data per blockchain transaction. That simply doesn’t scale well enough to support large enterprise level applications. And so, we decided to take the same underlying technology that we were using to power advertising buys for clients like Toyota and GroupM, and move it over to the oracle space.

在过去的10年里，我和Umbrella的高级团队专注于开发高性能和可扩展的产品，主要是在数字广告行业中。我曾担任买方平台Gimbal的联合创始人兼首席运营官，该平台最近从迪士尼手中收购了TrueX。

我们中的许多人对数字广告中的欺诈，腐败和普遍缺乏透明度感到沮丧。 2017年，我们中的一些人发现了以太坊，我们认为这将是解决数字广告问题的理想工具。因此，我们决定启动Lucidity为广告商提供透明、可扩展的营销分析解决方案。目前，Lucidity与一些领先的传统品牌合作，例如丰田、现代、肯德基和GroupM。

我们发现，甲骨文也经历了与我们在数字广告中经历的类似问题，主要是甲骨文速度慢且效率低下，每笔区块链交易只写入一块数据。这根本无法很好地扩展以支持大型企业级应用程序。因此，我们决定采用与丰田和GroupM等客户相同的基础技术来推动广告购买，并将其移至oracle空间。

问题4:目前市面上有哪些竞争对手？ Umbrella 的优势是什么？

What are the current competitors on the market? What are the advantages of Umbrella?

Current oracle solutions require you to compromise between security of the data or freshness / liveliness of the data. With Umbrella you can finally have both. We use multiple data sources so that you aren’t at risk of data manipulation at the source as we’ve seen in so many recent flash loan and oracle hacks. We also use a Delegated Proof of Stake system so that there is an economic incentive and disincentive layer unlike other leading solutions that run on Proof of Authority. And finally, with our Layer 2 merkle tree solution we can write thousands of pieces of data on a single blockchain transaction. So we have low cost data which ultimately means we can also provide more data.So, we’re just as secure and we’re much more affordable because of our technology.

当前的oracle解决方案要求您在数据的安全性或数据的新鲜度/活力度之间做平衡。 有了Umbrella，您可以同时拥有两者。 我们使用多个数据源，这样您就不会在源头上受到数据操纵的风险，就像最近在许多Flash借贷和oracle黑客中看到的那样，在数据源头就受到数据操纵。 我们还使用委托权益证明系统，因此与基于权益证明运行的其他领先解决方案不同，它具有经济激励和抑制层。 最后，借助我们 Layer 2解决方案，我们可以在单个区块链交易中写入数千个数据。 因此，我们拥有低成本的数据，这最终意味着我们还可以提供更多的数据。

因此，得益于我们的技术，我们既安全又便宜。

问题5：

Umbrella代币是如何分配的？他的激励分配部分是如何设计的呢？

Question 5:

How is Umbrella token distributed, and how is the incentive distribution part designed?

The $UMB tokens will be sold through Polkastarter’s IDO platform on 9 February. We will be selling approximately 5 million tokens.

The UMB token is designed to promote long term holding of the token. Over 70% of the tokens have a 4 year linear vesting schedule. Our Private buyers are subject to 18 month linear vesting schedules with no initial unlock. And we give rewards to token stakers via a secondary token called rUMB. rUMB can be redeemed for UMB 1 year after it is initiated. So a buyer has to believe in the long term value of the project.

UMB将于2月9日通过Polkastarter的IDO平台出售，将出售约500万枚。

UMB旨在促进令牌的长期持有。 超过70％的Token具有4年线性归属时间表。 投资者必须遵守18个月的线性归属时间表，且没有初始解锁权限。 然后，我们通过rUMB向Token参与者提供奖励。 rUMB可以在启动后1年内兑换UMB。 因此，投资者必须相信项目的长期价值。

问题6：

除了购买，用户都有哪些获得Umbrella的方式？

Question 6:

In addition to purchasing, what are the ways for users to get Umbrella?

We have programs for validators and developers to get UMB tokens. We believe they are crucial part of the ecosystem. We will also have various programs for the community who create art for the project, become ambassadors, serve on governance, help us with marketing, business development and much more.

And of course there is the liquidity mining feature where for staking UMB tokens, users get rewards and a share of the user fees.

我们为验证者和开发人员提供了获取UMB的程序。 我们认为它们是生态系统的关键部分。 我们还将为社区提供各种计划，为该项目创造艺术，成为大使，服务于政府，帮助我们进行营销，业务发展等等。

当然，还有流动性挖矿功能，通过此功能，用户可以使用UMB进行奖励，并获得一定份额的使用费。

问题7:

Umbrella都有哪些投资方？对于代币持有者而言，代币的作用主要体现在哪里？

Question 7:

How many companies invest in Umbrella?? What are the utilities of Umbrella?

We have a number of private investors who supported us through the early stages of the project. They include SRC Capital and Youbi Capital who were a couple of our initial supporters. In addition, we’re backed by NGC, Monday Capital, CMS, Zokyo and others in our Private rounds.

The UMB token can be used in two ways: 1) as a governance token, and 2) as a liquidity mining token where rewards are distributed for staking within the system and ultimately sharing of user fees.

我们有许多私人投资者在项目的早期阶段为我们提供了支持。 他们包括SRC Capital和Youbi Capital，他们是我们最初的支持者。 此外，NGC，Monday Capital，CMS，Zokyo等在私募融资中也为我们提供了支持。UMB可以通过两种方式使用：1）作为治理代币? 2）用于流动性挖矿

问题8：

Umbrella现在的数据表现如何？接下来有哪些计划？

Question 8：

Can you share us some statistics of Umbrella and what is your next plan?

So Umbrella currently supports approximately 1,000 datapairs ranging from the most commonly used crypto pairs, to middle and long tail of the crypto market, indexes, options data and real world assets like equities, Fx and commodities like oil and gas.

Over the next year, our goal is to on board new projects, increase the number of validators, and drive the cost of data down for the entire blockchain market. In parallel to that, we aim to decentralized governance in 2021.

Umbrella当前支持大约1,000个数据对，从最常用的加密对到加密市场的中长期，指数，期权数据以及诸如证券、外汇、石油和天然气等大宗商品。

新的一年，我们的目标是加入新项目，增加验证者的数量，并降低整个区块链市场的数据成本。 与此同时，我们的目标是在2021年实现分权治理。
