我们已经写了一点关于去中心化数据存储的报道,包括MaidSafe和Permacoin项目,尽管后者不是真正的完全去中心化的存储模型。
把这些项目添加到Storj中去 [PDF白皮书],我们可以得到一个有趣的想法,在一年的时间里分散存储可能变成什么样子,或许更少时间。
MaidSafe和Storj都是开源项目,包含一个协议和一个加密货币。都把数据拆成小块和分发在网络上。用户可以核实所有权,使用令牌访问他们的数据,比特币以同样的方式来验证用户和访问他/她的钱。
MaidSafe和Storj所不同的是在细节,但可能不太重要:Storj和MaidSafe开发商已经合作了一段时间,希望能够实现跨兼容性。
StorjTalk论坛管理员super3写道:“这将是伟大的,你可以存储文件在Storj或Maidsafe网络上,或者通过任意一个网络访问文件”。
为什么这很重要
对一般的互联网用户而言,去中心化的数据存储提供了两个巨大的利益:安全性和成本效益(例如,它会比Dropbox更便宜)。
首先,安全性。中心化的存储意味着某人在某地可以访问您的数据。只有你信任的人掌握着你的数据,中心化的存储才非常有用。去中心化不需要信任,就像比特币在货币上做的一样。
“这已经不是什么秘密,互联网用户的安全和隐私在过去几年一直是不安全的,”Storj博客的一篇文章写道。
“巨大的文件托管网站如互联星空已被关闭,政府机构,如美国国家安全局能够监控任何用户的互联网活动,并能访问看似’安全的’云存储主机的或任何文件或数据,像Dropbox或OneDrive,希望任何人存储个人信息在互联网之前,三思而后行,除非有很好的理由。“
MaidSafe似乎按类似的想法进行操作。
“我认为互联网已经成为一个很不自然的设计,我不忍看到人们失去对他们身份和个人思想的控制,”早在四月,MaidSafe CEO大卫欧文告诉我们。
“我想,由于人们的个人电脑有可用的计算资源,我们可以做一个更好的项目。 MaidSafe似乎是显而易见的答案,不是建立大型服务器群,用人们自己的电脑。创建一个所有计算机连接的大型网络,并允许人们访问网络和存储他们的信息以及沟通等。“
然后,还有钱的问题,通过分散存储,用户可以节省多少钱(甚至赚钱)。
Storj的开发者注意到,一旦他们的系统运作,他们认为用户可以安全地存储100 GB的数据,每月费用大约是Dropbox的四分之一。
“Storj计划大幅下降云存储的成本。用户只需要支付使用的空间,而不是容量。该网络的运营成本应该已经比中心化的供应商便宜得多,因为大多数网络将运行在用户的计算机上。用户不必支付全职员工的工资,办公室租金,加热和冷却费,股东利润等。“
更重要的是,无论是Storj和MaidSafe都将奖励节点(最终用户)分享他们的带宽来支撑去中心化存储的运作。这包括支付每个项目本身的加密货币- Storjcoins和Safecoins,分别支付 – 将来可能支付其他货币。
Storj的开发者提示,这可能不是一个很大的数目,但小钱也是钱:“如果一个人可以运行自己的公共Storj节点,他的回报是世界平均水平的2.1 MB / s连接带宽,3倍冗余,粗略估计,这个回报在Dropbox的价格是150美元每月。“
评论:很像流量矿石,但谁胜谁负,技术竞争的最终仲裁是市场。
How Blockchain Tech Could Revolutionize Data Storage
We have already written a bit about projects seeking to decentralized data storage, including MaidSafe and Permacoin, although the latter isn’t really a fully decentralized storage model.
Add to that list Storj [PDF whitepaper], and we can get an interesting idea as to how decentralized storage might look in a year’s time, perhaps less.
MaidSafe and Storj are both open-source projects that include a protocol and a cryptocurrency. Both break up data into pieces and distribute those across a network. Users can verify ownership and thus access their data with a token, the same way a Bitcoin user verifies and access his/her money.
The difference is in the details, but that might not matter too much: Storj and MaidSafe developers have been working together for a while and hope to achieve cross-compatibility.
“It would be great if you could store a file on the Storj or Maidsafe network, and access that file through either one,” writes StorjTalk forum administrator super3.
Why this is important
Decentralized data storage offers two huge benefits to the average internet user: Security and cost efficiency (e.g. it would be cheaper than Dropbox).
First, security. Centralized storage means someone, somewhere is going to have access to your data. That’s only useful insofar as you can trust the person/people holding your data. Decentralization eliminates the need for trust, just as Bitcoin first did with money.
“It’s no secret that the last few years have been a turmoil for the security and privacy of web users,” reads a post on the Storj blog.
“Enormous file hosting sites like Megaupload have been shut down, government organizations like the NSA having the capability of monitoring any user’s internet activity and being able to access any files or data that have been put on seemingly ‘secure’ cloud storage hosts like Dropbox or OneDrive, could make any person that wishes to store personal information on the internet to think twice about doing it, with good reason.”
MaidSafe seems to be operating under a similar idea.
“I thought the internet had become a very unnatural design and could not bear to see people lose control of their identities and personal thoughts,” MaidSafe CEO David Irvine told us back in April.
“I figured that with all the computing resource available in people’s personal computers that we could do a much better job with what we have. MaidSafe seemed like an obvious answer, rather than creating large server farms, use peoples own computers. Create a large network that all computers join and allow people to access this network and store their information there as well as communicate, etc.”
Then, there’s the issue of money, and how much of it a user can save (or even earn) through decentralized storage.
Storj’s developers note that, once their system goes live, they think that users can store 100 GB of data securely for about one-quarter of what Dropbox charges per month.
“Storj plans to drop the cost of cloud storage dramatically. The user would only have to pay for used space and not capacity. The operating costs of the network would already be much cheaper than a centralized provider, as a majority of the network will run on users computers. The users don’t have to pay for full time employees, office space, heating and cooling, shareholder profits, etc.”
What’s more, both Storj and MaidSafe will reward nodes (end users) for sharing their bandwidth to enable decentralized storage. This includes payment in each project’s own cryptocurrency — Storjcoins and Safecoins, respectively — as well as in other currencies, potentially.
Storj’s developers note this might not be a huge sum, but it’s something anyway: “For a person who could run their own public Storj node, the monthly revenue that could be reached with a world-average 2.1 MB/s connection, 3x redundancy and Dropbox prices comes to a rough $150 per month.”

这样风险不就更大了?

区块链存的都是小数据。如何驱动一个大的数据存储区块链是个在问题。

希望只是有用的数据存储在像MAIDSAFE的网络上。别是所有的数据都存在上面。

哦,去中心化存储要是真能实现就太棒了
但还是依赖于互联网的普及程度
