    IPFS是不错 但和Filecoin傻傻分不清楚可能会吃亏

    篇幅限制,我就只捡我认为重要的地方来说吧,可能数据上做的不那么细致,算是抛砖引玉吧,随着IPFS矿机的热炒,国内关于这个项目的文章和资料挺多的,对这个项目感兴趣的可以多去看看。

    什么是IPFS

    IPFS翻译成中文就是“星际文件系统”,一听就很科幻的感觉,有木有,它其实是一种分布式的传输协议,对,现在外面对IPFS最主流的表达就是下一代的颠覆HTTP的互联网传输协议。

    那么先理解了什么是http,也就更容易理解什么是IPFS了。咱们每天上网刷朋友圈都是基于HTTP协议,其使用域名寻址,也就是说你要打开一个网页的内容,在底层逻辑上,提出一个请求搜索这个域名所在的服务器位置,然后把相应位置的内容读取出来传输会到你的页面上展现出来。那么这里有个问题就是,你必须保证这个内容所在的服务器是开着的且内容未移动或删除,否则就是下图的状态。

    IPFS

     

    我们现在常用的这些APP、网站、你的朋友圈的数据都是放在中心化的服务器集群中存储,如果一旦出现故障、或者存储方恶意删除,你又没有本地备份的话,这些数据很容易丢失。

    而IPFS呢,不是基于这种域名寻址,而是内容寻址。它会从一个网页的内容计算出一个加密哈希值,这个值直接反应这个网页的内容。当IPFS被请求一个哈希时,它会使用一个分布式哈希表找到其所在的节点,验证数据并回传内容。而如果内容比较大的话,会分片成几部分再分别加密,需要下载的话可以同时从网站中不同的地方获取。

    相比HTTP,只要在IPFS网络中出现过的内容不用担心会随着时间推移因为服务器稳定性等问题而消失。

    IPFS和Filecoin的关系

    看我们公众号之前的投票IPFS票数最高,我不知道是不是大家都理解IPFS和Filecoin的关系,还是其实你们想了解的是Filecoin。

    目前市面上一个说法是Filecoin是IPFS官方推出的代币,这么理解貌似没错,因为IPFS也好Filecoin也好,白皮书都是同个人写的,但其中还是有一点问题的。

    前面咱们也讲了IPFS是一个分布式传输协议,而Filecoin是做在IPFS其上的激励层,通过token激励模式(矿工通过抵押代币存储内容获得激励),在IPFS上构建了一个去中心化存储市场,这俩还是有点差别的。

    团队及项目情况

    IPFS的作者Juan Benet,其也是Protocol Labs创始人,而Filecoin也是Protocol Labs这个公司旗下的一个项目。

    IPFS

     

    网络上关于这个人和公司的介绍内容不多,Juan Benet斯坦福大学计算机科学硕士毕业,这是他毕业后的第二次创业创办的公司,最早于2014年初始概念,到2015年创立项目,到是都没有什么特别的,唯一的亮点是IPFS曾在YCombinator(貌似国外挺有名)孵化竞赛中拿到了巨额的投资。

    另外需要注意的一点是,IPFS其实已经是一个可用的网络了。但目前关于Filecoin的官方消息倒是不多,Filecoin的推特好像几个月才更新一次消息,海外关于Filecoin的文章和视频也大多停留在去年IC0前后。

    资料汇总:

    Filecoin官网:http://filecoin.io/

    Filecoin Twitter:https://twitter.com/MineFilecoin

    IPFS 中文白皮书:https://gguoss.github.io/2017/05/28/ipfs/

    几个问题

    1. IPFS到底能不能颠覆HTTP

    这个口号看资料从2015年就开始喊了,但咱不能光喊口号,还是得遵从现实的逻辑。IPFS这个项目有很酷的地方,但要谈颠覆可能还有很长的路要走,看他们创始人之前的采访,应该也是要慢慢来,做5-10年的规划。

    当然有一点不能忽略,就是遇上了区块链,你要让那些主流网站和服务都去做改变难度还是不小,但对于区块链应用,对于DAPP,这种分布式的传输存储是刚需,你不会指望做一个DAPP最后还运行在中心化的服务器上,随便来个监管就玩完了吧。所以,如果未来有一天真是DAPP的时代,DAPP占主流市场,那么IPFS可以说潜力还是非常大的。

    2. IPFS和Filecoin是不是该区分来看

    就是说,需要注意的是,IPFS未来的价值,不意味着Filecoin也值同样的价值。这是我个人看法,大家可以自己想想。

    很多应用可以构建在IPFS协议上,或者说在IPFS上可以建立很多像Filecoin这样的项目。

    像目前已经有一些应用项目基于IPFS来实现了,如Akasha就是一个基于以太坊和IPFS的社交博客创作平台,还有咱们的大柚子EOS,底层存储也是采用的IPFS协议。而这些貌似和Filecoin没太大关系吧,EOS加上备用节点100多个节点,还会来支付Filecoin里的存储费用吗?(这里没查到太多资料,感觉是可以绕开Filecoin直接使用协议的,如有问题,欢迎指正)

    3. 对IPFS矿机在国内的炒作持谨慎态度

    Filecoin在去年进行了IC0,筹款了2.57亿美金,而这占比只有10%,总量20亿枚,其中70%以挖矿的方式产生。

     

    IPFS

     

    具体数据可参考:Filecoin:募资详情和Token分发详情https://zhuanlan.zhihu.com/p/33862906

    而IC0的代币是有超长锁定期,到现在第一批代币还未解锁,预计在今年6月解锁。目前个别交易所能买到的代币是交易所内部参加了之前募集得到的币做的期货,从理论上说这个价格是很容易被操控的,甚至交易所是否有作恶的可能性咱都不得而知,不具有太大参考性。

    团队锁币最长达6年时间,可见对于项目还是很有信心。但近期国内币圈的一些舆论,搞得让人感觉IPFS挺火热的,而国外却没太多动静,传闻6月代币解锁后官方会出挖矿计划,但现在还有一个月多点,官方还没任何消息,官网只有一个关于挖矿意向的调查表单,不免让人觉得蹊跷。

    国内稍微搜索下能发现不少做IPFS技术线下分享会的,浓浓的cx风,甚至上来就说错过了比特以太的挖矿就不要再错过IPFS,不免让人感觉只是为了卖矿机。包括国内近期很多对此项目的文章,貌似都直接把IPFS和Filecoin混在一起来解读,我觉得这里还是有点问题的。

    包括国内很多对此项目的文章,貌似都直接把IPFS和Filecoin混在一起来解读,我觉得这里还是有问题的。

    如果单从去中心化存储这一点来看的话,下面是目前几个做存储概念的主要项目市值,以rmb计算。

    IPFS

     

    结语

    IPFS是不错的项目,也有可能在未来颠覆HTTP,但我不认为想当然的就能把IPFS的价值和Filecoin的价值等同起来,这一点欢迎讨论。另外也要注意两点:

    1. 大众的非理性。

    2. 如果IPFS在几年后价值巨大,Filecoin可能会有更多用户,也会相应变得值钱,而这点其他存储概念项目可能没法比。但能值多少,现在的估值高不高,还值得商榷。
