不止比特币:告诉你区块链还有更多的场景

明明 2023-05-12 0

很多人都听说过区块链,也通过一些文章和课程对区块链以及其运行机制有了一定的初步了解。但是很多人仍然困惑,这玩意在真实场景下到底是怎么使用的。通过一些例子,我们先回顾一下什么是区块链。

简单来说,区块链是一个分布式的数据库,是基于去中心化的点对点网络构建的。因此每个节点都可以看到这个数据库的数据。每个节点都可以向这个数据库中写入新的数据,但是不能更改任何已经存在的数据记录。这是区块链的一个关键属性:透明性。

不止比特币:告诉你区块链还有更多的场景

那区块链到底是怎么应用的呢?

区块链最广泛的一个应用场景就是加密货币。比特币诞生于2008年,从此人们可以进行一种不需要第三方信任的交易。从此之后,又诞生了约1600多个不同的加密货币。

有人听说过"里程欺骗"吗?在二手车交易中,有人可以通过修改二手车的行驶里程来谋求更高的交易价格。一辆里程5w公里的汽车和一辆里程1w公里的汽车在二手车市场的售价是完全不同的。如果将汽车的行驶数据写入区块链会怎么样?每辆汽车的行驶数据都上链,且不可篡改和透明,那么这就是一个安全的证明,可以证明该该车的真实使用情况。区块链是追溯历史数据信息的完美的技术方案。

除了里程数据上链可以获益外,区块链也可以用来记录知识产权专利的数据。区块链就像是一个公证人的角色,可以证明和确认每个合法数据。

另外一个有趣的应用场景是数字投票。当前我们更多的是通过纸质投票或者通过中心化的第三方信任软件来投票。纸质投票成本高,第三方的信任软件存在中心化问题,有被篡改的可能。我们无法完全信任纸质投票或者第三方软件的记录结果,因为第三方机构有可能基于利益修改投票结果,黑客也可以通过攻击来修改结果。但是如果我们使用区块链来记录投票数据的话,那就不存在篡改问题了。所有数据都是基于全网共识之后提交的,没有任何人或者任何机构可以通过篡改数据来谋求利益。
