8btc:Sia近期还有什么计划?

David Vorick:For a long time, Sia has lacked a good testnet. This makes testing harder for us, but it also makes testing harder for the people building products on TOP of Sia as well. We are going to be releasing testnet software in the coming week. It will make life easier for app developers, will make testing easier for everyone, and it will mean fewer bugs. Fewer bugs in Sia, and fewer bugs in the tools that depend on Sia. There will be more information available soon.

非常长一段时间,Sia都缺少一个好的测试互联网。这使测试对于大家来讲愈加困难,同时也使那些在Sia平台创建商品的用户愈加难以进行测试。大家计划在将来一周发布测试互联网软件。如此会使APP开发者的工作容易一些,也使每个人的测试更容易一些,也意味着bug更少。Sia的bug更少,依靠于Sia的工具的bug也会更少。非常快就会发布更多信息。

近两个月,网盘查题频出,在第三方统计的月活跃用户排行榜前十的网盘中,已有包含华为网盘、腾讯微云、新浪微盘、115网盘、金山快盘、和互联网硬盘在内的六家关停或者调整了有关服务。伴随用户对云存储的需要增多,运营停止、数据安全、个人隐私等问题都需要进行解决。

对于有很多存储需要的一般用户而言,面对网盘关停的解决方法,不外乎烧钱用付费网盘,多买硬盘线下存储,与另一种打造在区块链上的,去中心化的云存储策略。

Sia就是一个运用区块链技术的去中心化云储存平台。相比较传统的云储存方法,去中心化的Sia系统可以使云储存更安全、更快捷、更低本钱。通过编码技术(erasure coding),加密技术,和区块链(blockchian),Sia既拥有传统的云储存功能,同时又解决了传统的云储存存在的安全隐私问题,保证用户上传的资起因自己学会,而不是任何云储存服务提供商;储存文件的主机不可以翻阅其所存储的文件,而且即便在系统大面积瘫痪的状况下文件也可以不受损毁。

Sia的设计使提供储存空间的服务器可以收到Siacoin(SC币)–Sia系统内置代币,以此勉励更多闲散空间成为储存空间提供商。Sia采取pow模式,Siacoin的发行方法是通过给矿工挖矿提供奖励来长期保证Sia这个去中心化互联网的稳定性。

依据IDC 2013年的报告显示,在将来四年内,全球云服务市场规模将增长到442亿USD,其中云存储的市场比率将从9%增长到14%,其规模将接近62亿USD,存储市场是增长最快的云计算服务。第三方报告显示,2015 年全球数据总量约为 8.6ZB,预计 2016 年将在 12ZB 左右,到 2020 年将超越 44ZB,等于全球平均每个人有超越 5500GB 的数据量。

庞大的市场需要让资金投入者对Sia充满期待。截至现在,Siacoin已经在Poloniex、ShapeShift、Bitsquare几家交易平台上线,国内第一家上线Siacoin的云币交易平台COO老猫评价:

“用去中心化方法满足存储及闲置空间双方的需要,是典型的 UBER 模式,所以说 SIA 是云储存行业的 “UBER”。解决了用户需要和闲散社会资源对接的问题,同样也解决了用户存储需要和闲置空间对接问题的 SIA 是否会成为没一块硬盘的全球最大的云存储公司?”

Sia诞生于去年5月,低调开发到今天,团队现在有四位全职职员,CEO David Vorick 是个26岁的年青小伙,毕业于伦斯勒理工学院,过去在IBM实习。Sia是Nabulous Labs旗下的项目,Sia平台里买卖额的3.9%归siafunds 所有,Nabulous Labs拥有大概90%的siafunds。Sia团队就是靠这部分siafunds的将来收益筹筹资金。在Sia基本完成后,Nabulous 计划要在其上打造一些盈利项目,这部分项目也可筹资。

Sia早期资金投入人和社区参与者张晓彤在Sia最初众售时就购买了siafunds,他向巴比特介绍,当时决定资金投入主如果看好开创者明确的思维和对项目的远见:

“Sia团队目前有4个全职开发职员, 团队的特征是有能力 , 实干和肯干, 专注于技术和商品的开发, 不炒作。”

对于现在Sia项目的进展,他十分认可:

“第一, 去中心化云储存的开发在技术上非常难, 第二,和其他的相同种类项目相比,Sia的开发进度是最快的, 而且其系统是最安全的。Sia的互联网已经在公开的环境下测试和运行了一年多, 其他的项目还没在公开的环境下运行或才开始公开地运行和测试。Sia的空间租用和文件推广托管智能合约的开发也走在前面, 简言之, 目前 Sia系统可以在去中心化的环境里用, 而其他的还不可以。当然Sia还需要健全, 进一步提升才能商业化运行。但Sia离商业化运行已经非常近了。”

老猫此前在《深度聊聊SIACOIN的资金投入机会》一文中过去提到,Sia 项目现在正在进行筹资谈判,不止一家资金投入商正在接触中;Sia开创者David Vorick近期同意了巴比特的专访,在这次的采访中,David也告诉大家,将会在将来一两周宣布有关消息。来看看David 跟大家推荐的有关Sia的其他内容:

8btc:请用你觉得通俗的语言介绍下啥是Sia?解决了那些问题?

David Vorick:Siacoin is a data storage platform. It’s a way to put files online and keep them safe. But unlike other data storage platforms, Sia does not require you to trust your data with a single company or platform. On Sia, all of your data is fully encrypted, and is spread all over the world. Sia is also a completely open source project with no central hardware. The parent company of Sia only hosts a very small percentage of the data on the network. If our company fails or disappears, all of the data is still safe and accessible. We don’t have any control, all of the control belongs to the user. Data is one of the most important resources you can have, it makes sense that you would be in control of your data instead of being forced to trust someone else to keep your data safe.
Sia是一个数据存储平台。它可以将文件放到互联网上,并保护文件的安全。但与其他数据存储平台不同,Sia并不需要你将数据推广托管给某个公司或者平台。在Sia,所有些数据都会进行加密,并分散到全世界。Sia还是一个完全的开源项目,没任何中央硬件。Sia的母公司只能在互联网上推广托管很小的一部分数据。假如大家的公司失败或消失,所有些数据仍旧是安全的并且可访问的。大家不会控制数据,而是由用户全权掌控。数据是你们可以拥有些非常重要的资源之一,由用户自己控制数据而不是被迫去信赖别的人来保证数据安全,这是非常有意义的。

8btc:请介绍一下你接触数字虚拟货币和区块链的经历吧,是什么促进你创建Sia这个项目?

David Vorick:I have been following 比特币 closely since 2011. Starting in 2013, I started following the cryptocurrency research community as well. For 3 years now I have been reading papers and closely following major security and scalability events in the ecosplayystem. I originally did it because I thought that blockchains were fascinating. I now believe that they are going to be a major driving force in the global economy over the next 10-30 years. 比特币 has, by far, the best chance at being the new backbone for money. But I also realized that blockchains were good for things other than money. And in particular I have a paranoia around my data. When I upload my files to the cloud, Google, Apple, Amazon, or whichever provider has full access to them. They can see everything, and they can delete everything. What happens to my data is fully under their control. I wanted something better than that. And I realized that we could use a blockchain to achieve that. When the data is on one platform, you are at the mercy of one company. But if the data is spread all over the world, protected by dozens or hundreds of different people, then you have something secure. Sia allows us to do this without incurring great expenses.
自2011年,我就开始关注BTC。从2013年,我开始关注数字货币研究社区。现在3年过去了,我已经读过不少报告,并且密切关注这个生态系统中发生的重大安全和扩容事件。我刚开始是如此做的,由于我觉得区块链是让人着迷的。我目前相信区块链在将来10到30年将会成为全球经济的要紧推进力。现在为止,BTC拥有成为货币新骨架的最好机会。尤其是,我对于数据可谓是一个偏执狂。当我把数据上传到云端,Google,苹果,亚马逊或者其他提供商(一般为多个,由于很多提供商用其他提供商的硬件),这部分提供商完全可以访问这部分数据。他们可以看到所有事,可以删除所有些东西。我的数据完全处在他们的掌控之下。我想要比这要好的东西。我意识到大家可以用区块链来达成这一点。当数据被放到一个平台上,你就处于某个企业的摆布之下。但假如数据通过被分散到全世界的方法来进行存储,并由数十个,数百个不一样的人来保护,那样你就可以确保这部分数据的安全。Sia就能做的这部分,并且本钱非常低。

8btc:你觉得云储存的市场有多大?你如何看待这个市场和市场里的角逐者呢?

David Vorick:Cloud storage is a massive industry, there are billions of dollars per year being handed to companies who are trying to protect data. And, that amount is growing quickly. We’ve entered the age of ‘Big Data’. Everybody is trying to collect as much data as possible, because data gives you an edge over your competition, and makes impossible things easy. Storage is getting cheaper, but data demand is growing faster than storage is getting cheaper. For some data, it’s important that the data is always safe. For some data, it’s important that the data can be quickly sent all over the world. Sia is better than the traditional technologies for both of these scenarios. Sia can host data in more than 30 countries. Not even Amazon can say that. Sia is very small, and very young. By the time we are as large as Amazon, we will be able to host data in every city with more than 100,000 people. Because Sia is decentralized, we can do this much more efficiently than Amazon can. Amazon would have to set up a datacenter in each city. But Sia allows anyone to store data. And because we use a blockchain, we know that if they lose the data, they will lose a lot of money. Even more, it’s okay if they lose the data, because the data is highly redundant.
云储存是一个巨大的产业,每年数亿USD被交给一些公司作为数据保护费。并且,这一数字还在迅速上涨。大家已经进入了‘云数据年代’。每个人都在尝试采集尽量多的数据,由于数据可以带来角逐优势,轻松将一些不可能的事变为可能。存储本钱变得愈加低,但数据需要增长的速度要比存储本钱减少的速度更快。对于一些数据,安全至关要紧。还有一些云数据,可以在全世界迅速发送尤为重要。Sia在这两方面要比传统技术做的更好。Sia可以将数据推广托管到超越30个国家。这一点,即便是亚马逊也不可以说可以做到。Sia的规模还非常小,还很年青。当其规模达到像亚马逊一样时,大家将可以把数据推广托管到每个城市,推广托管给超越100000人。由于Sia是去中心化的,大家在这一点上可以比亚马逊愈加高效。亚马逊需要在每个城市打造一个数据中心,但Sia允许每个人存储数据。并且由于大家用了区块链,大家知晓假如他们丢失了数据,就会损失不少钱,或者更糟糕,但通过区块链,假如他们丢失了数据,也没关系,由于数据是高度冗余的。

8btc:跟现在市场上的分布式云储存的角逐者譬如storj和maidsafe相比,sia的优势或者特点有哪些?(譬如用PoW因此会愈加安全?)

David Vorick:I try not to focus too much on our competition. The goals of each platform are slightly different. MaidSAFE is more ambitious. Storj seems more focused on the end consumer, where Sia is more focused on enterprises. But I will say that in decentralized systems, the security is very difficult, and the programming is very difficult. All three platforms have now learned that first-hand. It has been two years, and nobody can say that they’ve built a successful, stable network yet. Sia has the most working. If you are patient, you can put a few gigabytes of data onto our network and have it be fully decentralized. Nobody else can say that. But we are also short of our goal. It should be *easy* to put a few GBs on our network, and the network should not experience any instability even if you are putting millions of gigabytes on the network. We are not there yet. And that is only the first hurdle. Things must also be secure. Of the three, the Sia team has the strongest security background, and we have prioritized security from day one. I have not formally audited our competitors, because I don’t think it’s the best use of my time. But, from what I know about their algorithms for finding the best hosts, for splitting up and deduplicating data, and for verifying that hosts are actually storing the files, I think a sophisticated attacker will be able to cheat on our competitors platforms. And because the platforms are anonymous, I think that they will see actual cheaters on their platform who will drive prices up and reliability down . I am worried because the types of security events that our competitors talk about do not seem to cover even most of the things that the 比特币 research community is most worried about. We will find out.
我尽可能不把太多的重点放在大家的角逐上。每一个平台的目的都略有不同。MaidSafe更雄心勃勃。Storj好像更关注终端消费者,而Sia则更侧重于企业。但我要说的是,对于去中心化系统,安全是很不简单的,编程也是很不简单的。这三个平台都已经获悉了这一点。已经两年了,无人可以说,他们已经打造了一个成功的,稳定的互联网。Sia进行的工作最多。假如你有耐心,你可以把几个字节的数据存储到大家的互联网并且是完全去中心化的。别的人却没办法做到。但大家也缺少大家的目的。把几个GB数据放到大家的互联网上应该不难,即便是把数百万GB数据放到大家的互联网上,互联网也不会出现不稳定的状况。不过大家还没进展到这一地步,并且这还只不过第一个障碍。这部分数据还要可以保证是安全的。这三个平台中,Sia团队拥有最强的安全背景,并且从第一天开始就把安全放在第一位。我没正式审核大家的角逐对手。由于大家觉得没必要把时间消耗在这一方面。但,据我所知,他们探寻最好推广托管,离别和重复数据,与验证推广托管的算法事实上就是存储文件。我觉得一个复杂的攻击者将可以欺骗大家的角逐对手的平台。由于平台是匿名的,我觉得他们会在平台上看到实质的骗子,这部分人将推进价格上涨和使可信任性降低。我非常担忧,由于大家的角逐对手谈论的安全事件的种类好像并没涵盖甚至大部分的BTC研究社区最担忧的东西。

8btc:Sia系统目前的最新进展怎么样?Sia还面临或者还需要解决那些问题?

David Vorick:Sia is making lots of progress. Since our last release, one month ago, we have added several thousand lines of code to the project. Lots of it is testing. Lots of it is upgrading stability. Lots of it is fixing bugs. Our v1.0.0 release was very buggy, and this is something we are taking seriously. Externally, it does not seem like much is happening, but internally we have been very busy. Our biggest concern today by far is platform reliability, and we now have tools that make it easier for us to find and fix bugs. Parts of the code were so slow that, even though it was working correctly, just the slowness alone was causing bugs. We have made that code faster. I would say we’re about halfway done making fixes. I think it is the right use of our time. Until Sia is a stable network, Sia is unsuccessful. Making Sia successful is the most important thing to me. Having 1 million users doesn’t mean anything if they all struggle to use the product. I cannot be proud of that. But having 1000 users who all enjoy using Sia, that would make me happy. That is a foundation that you can build off of. We will get to a strong foundation. It is our focus above everything else.
Sia正在获得不少进展。自大家一个月之前的商品发布之后,大家已经为该项目添加了数千行代码。其中一部分正在进行测试,一部分用于更新稳定性,还有一些是为了修复bug。大家的1.0.0版本用于不少bug,这是大家正在认真对待的事情。从表面上看,大家近期确实没什么动静,不过,大家内部是很忙的。大家现在最大的担心是平台的靠谱性。大家目前有了工具,使大家更容易找到和修复错误。代码部分进展是很缓慢的,尽管代码工作正在朝着正确的方向进行,只不过这种缓慢本身就会致使错误。大家已经加快了代码工作,现在大约完成了一半的修复工作。我觉得这才是用时间的正确方法。在Sia互联网稳定之前,Sia就不可以算得上成功。让Sia成功对于大家来讲是非常重要的事情。假如用户在商品用上陷入挣扎,那样即便拥有100万用户也没什么意义,也不可以令我感到自豪。但拥有1000可以享受用Sia的用户,如此会令我特别高兴。这是大家进步的基础。大家将获得一个强大的基础。这就是大家最大的关注点。

8btc:现在是不是有一些商业合作正在洽谈?Sia距离商业化应用还有多远?

David Vorick:We have started to expand our business networks. There are some partnerships in the works, but I do not want to share too much information. Our prices are extremely good. This has many people interested. Many are waiting to see if we can make things more stable. A few are taking risks despite the instability. We have built something very powerful, and it’s grabbing attention. But it’s too early for me to say much more.
大家已经开始扩展大家的商业互联网。大家进行着一些合作,不过我并不想推荐太多有关这部分的信息。大家的价格是很好的。这让大多数人非常有兴趣。大多数人都在等着看大家是不是可以让事情愈加稳定。极少有人会不考虑这种不稳定性而冒险。大家已经打造了很强大的东西,它吸引了大家的注意力。不过,现在还不适合说太多。

8btc:通过购买存储合约进入这个生态系统所需要的资金现在大约为$2.25/TB/月,这远远低于角逐对手S3的$29/TB/月,或Dropbox的$9.9/TB/月。按当时写文章时的价格来算,用储存系统大概需要$2.25/TB/月,伴随币价上涨,用系统的本钱上升,如此是否会致使真的想要用储存系统的人,不期望代币价格上涨?

David Vorick:The price of storage is independent of the price of the coin. The storage marketplace on Sia is highly competitive. If your price is too high, you do not get contracts. Hosts are very aware of this, and are continuously adjusting their prices to be competitive, so that people will choose them to host data. As the price of the coin goes up, the hosts adjust their prices down. We saw this happen very quickly when the price spiked from 30 satoshis to 150 satoshis. The cosplayt of storage in 美元 barely moved. As the price of the coin went up, hosts asked for fewer coins, because they knew it would make them competitive. And when a few hosts did this, all of the other hosts had to do it as well, because they were no longer getting contracts. Sia has been designed to be extremely competitive. Either you sell at a price that beats your competitors or you don’t get any revenue at all. And because there are dozens and dozens of competitors, some of whom are anonymous, there is no chance of collusion, unions, or pacts. The only way to make money is to compete.
储存价格与币价无关。Sia的储存市场是很具备竞争优势的。假如你的价格过高,你就不可能获得合同。推广托管机构意识到了这一点,并不断地调整他们的价格来保持竞争优势,所以大家选择他们来推广托管数据。伴随币价上涨,推广托管方将价格下调。当价格从30聪暴涨到150聪时,这样的情况就会非常快出现。以USD计的存储本钱极少会变动。当币价上涨时,推广托管方收取的币就会少一些,由于他们知晓如此可以让他们愈加竞争优势。当一些推广托管方如此做时,所有其他推广托管方也不能不如此做,由于他们没办法再获得合同。Sia的设计使它很具备竞争优势。无论是你以击败你的角逐对手的价格供应,还是你一点收入都没都一样。由于有几十个角逐对手,其中一些是匿名的,没机会进行勾结,联合或者协定。赚钱的唯一方法就是角逐。

8btc:你对国内市场如何看?为何选择在中国的云币交易平台上线?

David Vorick:We are very excited to be involved with the Chinese market. There is a lot of demand for storage in the US, but China is hungrier. I think that China could end up being more than half of our ecosplayystem, and we are glad for it. Yunbi is a progressive, inspirational exchange and we are honored to be one of the few assets traded on their platform. I think it is common for the West to overlook China, and I think that is a big mistake. People often underestimate China. We are trying not to do that.
大家非常高兴可以参与到国内市场。美国确实具备非常大的存储需要,不过,中国的需要饥渴。我觉得中国最后可以占有大家生态系统的一半还要多,大家对此特别高兴。云币是个有进步并且激励人心的交易平台,大家非常荣幸可以成为少有些几种在其交易平台上线的资产之一。我觉得,西方国家忽略中国是非常常见的,我觉得这是一个巨大的错误。大家常常低估中国。大家正在努力不如此做。
