比特币和区块链是近期最流行的流行语之一。即使是从未开采过加密货币或了解其工作原理的人也在谈论它。听到区块链炒作告诉它，区块链现在将：
解决收入不平等 让所有数据永远安全 让一切变得更加高效和无需信任 使银行系统冗余 拯救地球
但是，到底什么是区块链？它真的可以做所有这些事情吗？区块链能否为医疗保健、金融、供应链管理和音乐版权等各行各业带来惊喜？
在本文中，我试图通过研究零售供应链管理中的区块链实施以及它如何带来更高的透明度、可追溯性和问责制来回答这些问题。
零售供应链管理
我们将研究以下场景，其中制造商准备的零售产品（棉衬衫、牛仔裤和 T 恤）通过运输和批发商转移到零售商。
我们将使用区块链来跟踪这些产品的移动以及产品交付的状况。这样，当产品到达零售商时，如果任何产品有任何问题，我们都可以追溯问题的根源，并设定责任。
让我们开始吧。
什么是区块链？
从技术上讲，一个区块是一组有序的交易，而区块链是一个区块链表，通过密码学产生的哈希值连接在一起。
您可以将区块链视为数据库的等价物，几乎没有其他属性。
一致性——进入的数据不能与已经在区块链中的其他一些数据发生冲突 不可变的——数据只能以追加模式输入 负责任的——输入的数据被锁定给所有者，它是可复制和可用的 去中心化——最后，每个人都同意区块链中事物的状态，没有中央方
让我们从这些单独的块是什么开始。
一个区块由一组交易组成，这些交易在整个区块链中是唯一的。每个块都由一组特征组成，如下图所示。
