下放 / Blockchain as decentralization

升级、抵御黑客攻击等产生的维护费用都是由它背后的阿里巴巴承担,假如有一天阿里巴巴耍性子说“我要去看诗和远方”,不再维护支付宝,那我们便无法使用支付宝了。

We talked about a centralized example in the first section of this course: Alipay. The maintenance costs of Alipay’s transaction process, system upgrade, and hacker attack are all borne by Alibaba behind it. If one day Alibaba decided not to maintain Alipay anymore, then we can’t use Alipay anymore.

而区块链项目核心就是去中心化,其背后是没有类似阿里巴巴这样的中心化机构去维护的,整个网络由全世界用户自愿去维护,如果没有利益驱使,基本不会有用户去做这件事(毕竟吃力还不一定讨好)。

The core of the blockchain project is decentralization. There is no centralized organization like Alibaba to maintain it. The entire network is voluntarily maintained by users all over the world. If there is no interest, there will be no users to do this.
