Steemit 的数据究竟是存储在哪里的？

Steemit的所有内容究竟存储在哪里？

我对比特币和区块链有一定的了解，比特币的全节点存储了所有的交易记录，而矿工是在进行计算，确认交易。

Steemit也是区块链的应用，可它和比特币完全不同，它是内容形式的，数据太多了，它的数据都存储在它的全结点上吗？我严重怀疑，那全接点的容量就太大了，普通人完全没法参与，那它的基础设施是由steemit 公司提供的吗？这样又不太象去中心化的应用了。本人愚钝，查了一些资料，也没能搞清此问题，还望高人指点。

我曾经从这几位的文章中获益，谢谢。就此问题试试向他们咨询。 @xiaohui @peterchen145 @myfirst @yuxi @liangfengyouren @oflyhigh @laodr

    相对于比特币来说，steem确实区块的容量非常大，而且还在不断地增大，但它仍然是却中心化的，是否中心化与区块数据大小无关，而在于是否由中心机构来控制。

    在steem区块链每个人都可以做节点，它并不属于任何组织，Steemit只是其中一个应用。

    不过想做Witness确实需要一点门槛，硬件上要求也不算高，安装节点服务最低要求 8GB的 RAM, 100GB 的硬盘, 这个配置家用电脑的主流配置都没问题，另外网络环境也要好一点，不然会丢失数据。

    我觉得主要门槛在于技术上，并不是每个人都会捣鼓安装这个服务（Witness Server），我看了几遍说明，反正是看不懂。

    也不知道回答的是否正确，希望大咖来补充解答更正。

        Steemit的witness节点都必须有能力参与系统的内容存储，否则会影响到他出块，出块出错次数到一定数量的时候，该witness就会被剥夺witness资格，后来者居上。一直维持固定的witness数量。庞大的系统里总会有人有这样的能力的。

                  steemit 是由社区选出来的20人做mining,这里是叫witness,他们的server是存完全部资料，为了安全，整个社区是有几百个witness,不过真正mine到的是前二十，所以在steemit是需要德高望重的人才能进入前二十，你可以到steemd.com 按witness 看
