再次歡迎@Sam，我們正式開始吧~
Welcome again @Sam ，Okay, let's start.
問題1：
可以從您的角度，先給我們社區的小伙伴簡單介紹一下Umbrella 這個項目嗎？它的願景和使命是什麼？
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 $0.00 as possible. We believe only once data is incredibly cheap will we have a thriving decentralized world. With our technology, we believe we have a massive cost advantage over the competition. And so we will make the most commonly used data available for free. And to support continued innovation by startups and smaller enterprises, we'll offer free data tier.
Umbrella Network有兩個主要任務。 首先， Umbrella希望將我們正在建立的Oracle的治理權下放。 我們認為， oracle是分散應用程序的關鍵基礎架構。 因此，我們認為至關重要的是，所有權和控制權不能由一個人或一小撮高管人員掌握。 這就是為什麼我們決心將權力移交給社區的原因。
第二個目標是使鏈上數據的成本盡可能接近$ 0.00 。 我們相信，只有數據便宜到令人難以置信的程度，我們才能擁有蓬勃發展的去中心化世界。 憑藉我們的技術，我們相信我們在競爭中擁有巨大的成本優勢。 因此，我們將免費提供最常用的數據。 為了支持初創企業和小型企業的持續創新，我們將提供免費的數據層。
問題2:
請問為什麼會選擇波卡？
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.
想談一談為什麼我們既選擇Polkastarter作為IDO ，又計劃在Polkadot上進行開發。因為我認為它們之間息息相關。
Polkastarter社區具有與YEarn和該領域其他領頭羊相媲美的潛力。在這裡啟動的項目的質量優於我們在市場上看到的任何其他項目。只需看一下清單： YOP Finance ， Bridge Mutual ， MahaDAO等，這些項目就是DeFi的未來。因此，我怎麼能拒絕與他們一起坐在一個房間裡的機會。
當然，重點放在Polkadot 。雖然我們目前是在Ethereum上創建，但我們有意在短期內轉移到Polkadot 。 Polkadot的優勢太明顯了，從低廉的交易成本到互操作性以及跨平行鏈啟動和發送消息的能力，這些都是區塊鏈應用不可思議的促成因素。
我相信Polkastarter社區及其項目生態系統會促使Polkadot發揮其全部潛力。而且， Umbrella Network希望為這個令人驚訝的團隊提供底層的Oracle基礎架構。
問題3：
可以介紹一下你們團隊背景和故事嗎？
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.
在過去的10年裡，我和Umbrella的高級團隊專注於開發高性能和可擴展的產品，主要是在數字廣告行業中。我曾擔任買方平台Gimbal的聯合創始人兼首席運營官，該平台最近從迪士尼手中收購了TrueX 。
我們中的許多人對數字廣告中的欺詐，腐敗和普遍缺乏透明度感到沮喪。 2017年，我們中的一些人發現了以太坊，我們認為這將是解決數字廣告問題的理想工具。因此，我們決定啟動Lucidity為廣告商提供透明、可擴展的營銷分析解決方案。目前， Lucidity與一些領先的傳統品牌合作，例如豐田、現代、肯德基和GroupM 。
我們發現，甲骨文也經歷了與我們在數字廣告中經歷的類似問題，主要是甲骨文速度慢且效率低下，每筆區塊鏈交易只寫入一塊數據。這根本無法很好地擴展以支持大型企業級應用程序。因此，我們決定採用與豐田和GroupM等客戶相同的基礎技術來推動廣告購買，並將其移至oracle空間。
問題4:目前市面上有哪些競爭對手？ Umbrella 的優勢是什麼？
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.
當前的oracle解決方案要求您在數據的安全性或數據的新鮮度/活力度之間做平衡。 有了Umbrella ，您可以同時擁有兩者。 我們使用多個數據源，這樣您就不會在源頭上受到數據操縱的風險，就像最近在許多Flash借貸和oracle黑客中看到的那樣，在數據源頭就受到數據操縱。 我們還使用委託權益證明系統，因此與基於權益證明運行的其他領先解決方案不同，它具有經濟激勵和抑制層。 最後，借助我們Layer 2解決方案，我們可以在單個區塊鏈交易中寫入數千個數據。 因此，我們擁有低成本的數據，這最終意味著我們還可以提供更多的數據。
因此，得益於我們的技術，我們既安全又便宜。
問題5：
Umbrella代幣是如何分配的？他的激勵分配部分是如何設計的呢？
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將於2月9日通過Polkastarter的IDO平台出售，將出售約500萬枚。
UMB旨在促進令牌的長期持有。 超過70 ％的Token具有4年線性歸屬時間表。 投資者必須遵守18個月的線性歸屬時間表，且沒有初始解鎖權限。 然後，我們通過rUMB向Token參與者提供獎勵。 rUMB可以在啟動後1年內兌換UMB 。 因此，投資者必須相信項目的長期價值。
問題6：
除了購買，用戶都有哪些獲得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.
我們為驗證者和開發人員提供了獲取UMB的程序。 我們認為它們是生態系統的關鍵部分。 我們還將為社區提供各種計劃，為該項目創造藝術，成為大使，服務於政府，幫助我們進行營銷，業務發展等等。
當然，還有流動性挖礦功能，通過此功能，用戶可以使用UMB進行獎勵，並獲得一定份額的使用費。
問題7:
Umbrella都有哪些投資方？對於代幣持有者而言，代幣的作用主要體現在哪裡？
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.
我們有許多私人投資者在項目的早期階段為我們提供了支持。 他們包括SRC Capital和Youbi Capital ，他們是我們最初的支持者。 此外， NGC ， Monday Capital ， CMS ， Zokyo等在私募融資中也為我們提供了支持。
UMB可以通過兩種方式使用： 1 ）作為治理代幣 2 ）用於流動性挖礦
問題8：
Umbrella現在的數據表現如何？接下來有哪些計劃？
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當前支持大約1,000個數據對，從最常用的加密對到加密市場的中長期，指數，期權數據以及諸如證券、外匯、石油和天然氣等大宗商品。
新的一年，我們的目標是加入新項目，增加驗證者的數量，並降低整個區塊鏈市場的數據成本。 與此同時，我們的目標是在2021年實現分權治理。
