导读
这篇 PDF 调查报告以问号形式质疑 Filecoin 是否是 2.57 亿美元的庞氏骗局,审视其代币经济与估值。作者在评论中说明这是与代尔夫特理工大学硕士生合作的研究,并用 Dropbox 约 500PB 用户数据作对比,认为 Filecoin 被高估。
HN 关注点:Filecoin 的估值与 ICO 泡沫争议,以及 IPFS 技术价值是否被代币项目带偏。

补充IPFS 的可用性源于 NAT 穿透难题,若个人服务器能自由部署并通过 HTTP 访问,其必要性会下降;Filecoin 热度则借了 DApp 浪潮。
我认为这条的置顶评论应该谈 Filecoin,而不是每天在这里看到的又一条对 Bitcoin 的无知评论。少人谈的一点是:多数人觉得 IPFS 有颠覆性,但我认为 IPFS 自身也容易被颠覆。IPFS 有用的主因是没有简单的 NAT 穿透方式,普通人很难在笔记本或手机上跑自己的服务器。IPFS 引入各种技术绕过这个问题,但我认为能自由地在自己的设备上架设服务器才是核心问题。你其实不一定需要全球可寻址的不可变文件存储,因为除非是静态图片,很多文件一直在变,而且人们想私有地存储和分享文件。也就是说,如果出现一种新技术,让人能在任何地方架设自己的服务器并通过 HTTP 访问,那我看不出为什么还需要 IPFS。这可以由创业公司、其他协议,甚至创新型的 ISP 来做。IPFS 现在这么热,是因为它搭上了 DApps 浪潮,人们想用以太坊应用加 IPFS 做文件存储;但我玩了一下后觉得它更适合……

I think the top comment for this should be about Filecoin, instead of just another uninformed comments about Bitcoin that we see here every day. That said, one thing most people don't talk about is: I think most people think IPFS is disruptive, but I think IPFS itself is susceptible to disruption. The main reason why IPFS is useful is because there's not an easy way to do NAT traversal therefore it's super hard for people to run their own server on their laptop or mobile devices. IPFS introduces all kinds of technologies to get around this, but in my opinion the ability to freely set up your own server on your device is the core problem. You don't really need a globally addressable immutable file storage, because unless you're dealing with static images, a lot of files DO change all the time, and people want to store and share files privately. Which means, if there's a new type of technology that lets people do just that--set up their own server anywhere and make it accessible via HTTP--then I don't see why we really need IPFS. This could be done by startups or other protocols, but even by some innovative ISPs, which decide to change their business model to compete against edge nodes that capture most of the value (such as Google, Facebook, etc.) In my opinion, the reason IPFS is so hot nowadays is because it's riding the DApps wave where people want to build Ethereum apps with IPFS as a file storage. But after playing around with it a bit I think it's much better at this point to just use Github to host your file and use Ethereum as database because the whole point of immutable apps is in the data and transactions, not in the static files. But I would love to be corrected. If anyone actually think IPFS is essential to DApps, feel free to correct me and educate me.
亲历作者回应:与 Dropbox 约 500PB 存储量对比,Filecoin 估值过高;研究来自 TU Delft 区块链实验室。
【作者】从我们的 PDF 里摘一段简短回答:“考虑到 Dropbox 目前持有约 500PB 用户数据,可以说 Filecoin 被高估了。” 这项研究是我们与代尔夫特理工大学一名硕士生做的。写论文时的开放实验记录在:https://github.com/Tribler/tribler/issues/3097 。注意 TUDelft 的 http://blockchain-lab.org 目前有 8 位教授,多名科学家和 38 名硕士生正在改进我们自己的类 Filecoin 系统,基于我们的 Trustchain fabric:https://github.com/Tribler/tribler/issues?q=is%3Aissue+is%3Aopen+label%3A%22MSc+course+work%22 。这里是欧洲最大的区块链实验室之一。

[Author here] short answer taken from our .PDF file: "Considering that Dropbox [53] currently holds around 500 petabytes of user data [54], one could argue that Filecoin is overvalued." Study we conducted with a master student at Delft University of Technology. Open lab notes when writing this paper: https://github.com/Tribler/tribler/issues/3097 Note TUDelft has currently 8 professors in their http://blockchain-lab.org Various scientists and 38 master students working on improving our own Filecoin-like system, based on our Trustchain fabric: https://github.com/Tribler/tribler/issues?q=is%3Aissue+is%3Aopen+label%3A%22MSc+course+work%22 It's home to one of the largest blockchain labs of Europe.
质疑对 Filecoin 失望,认为 IPFS 本身优秀,但核心开发者被 ICO 分散了精力。
Filecoin 让我非常失望。IPFS 是极好的技术,但主要开发者被又一个可疑的 ICO 带偏,这是我们最不需要的事。

Filecoin is a huge disappointment to me. IPFS is fantastic technology, but the main developers getting sidetracked with yet another scammy ICO is the last thing we need.
