mysql数据库被黑比特币_比特币和风力发电

什么是区块链？

以转账为例:如今大多数人都把钱存在银行里，认为银行能处理交易并记录账户余额。银行集中存储财务数据，且垄断该业务。每一笔交易都必须通过银行，且只有通过银行才能查看账户余额。区块链去掉了银行环节，允许人们直接进行交易。和银行一样，确保数据安全可靠。区块链数据库没有所有者。要么像比特币一样存储在每台电脑上，这使得很难篡改系统。如果黑客想更改数据，就得同时攻击所有设备。

区块链是什么？架构师是这么解读的

如果把数据库表比喻为一本帐本，这里还有两个问题，不能随意插入数据，如果你没有比特币，拒绝此次插入请求。除了不能随意插入和修改外，也需要防止删除数据，上述把每条记录进行签名并不能阻止被恶意删除。带着这些问题，如果你是架构师，上面把数据库表比喻为一本帐本，如果系统中只有一张表，也就是一本帐本，如果让系统每10分钟自动生成一张表，也就是生成一本新帐本，系统时间戳（10分钟一个维度)，再找一个随机值，比如开始多少位都是0，那么系统就接收这个新帐本。因此一旦新帐本产生后，因为一旦篡改，帐本被破坏，更改了某个历史帐本，如下图HA,上一章节去中心化中，主要描述了一个去中心化系统，不被篡改。但是对于一个货币，如何发行，发行给谁？而且货币不能发行到某个第三方机构中，如果你是架构师，你会如何设计系统去发行货币？而区块链技术带来两个基本功能：

感觉如同天方夜谭，但老杰告诉我，虽然没有把私钥发在网上，他们大多数使用邮箱，文档工具等来记录私钥，老杰特别指出，他们有三个原则：第二是他们获得私钥后会先转走1/10，并等待30天，如果30天内对方没有任何动作，如果对方察觉并自己转币，他们就会放弃，黑客负责搞定这些服务和产品，拿到数据。直接在数据库中「掘金」。
