【区块链运作机制】什么是区块链及其运作方式?

  区块链运作机制

  If you're interested in technology, there's a good chance you’ve probably heard the terms Bitcoin, Crypto, Ethereum, or even "distributed, decentralized ledgers."

  如果您对技术感兴趣,那么您很有可能已经听说过比特币,加密货币,以太坊,甚至“分布式,分散式分类帐”。

  You’ve probably heard people talk about cryptocurrency and encryption algorithms, about the end of "intermediaries" and so on.

  您可能已经听说过人们谈论加密货币和加密算法,有关“中介”的结尾等等。

  It's easy to assume that cryptocurrency (eg: Bitcoin, Ripple, Ethereum, Litecoin, etc.) are the same as blockchain. They're not.

  很容易假设加密货币(例如:比特币,Ripple,以太坊,Litecoin等)与区块链相同。他们不是。

  Cryptocurrenciesare a clever application of a much cleverer technology –the Blockchain.

  加密货币是更聪明的技术-区块链的聪明应用。

  In this post, I will cover some of the basic concepts of the blockchain so you understand what it is, how it must be conceptualized, and what can be built on top of it.

  在本文中,我将介绍区块链的一些基本概念,以便您了解区块链的含义,如何将其概念化以及可以在其之上构建的内容。

  But as with all things, they make more sense if you understandwhythey were invented, before you get into what they do. That context will help you grasp what problem the blockchain was designed to solve.

  但是,与所有事物一样,如果您在了解它们的用途之前了解了它们被发明的原因,它们就更有意义。该上下文将帮助您掌握区块链旨在解决的问题。

为什么要使用区块链?(Why use blockchain?)

  Great question. So glad you asked. Let's sit back and do a small thought experiment.

  好问题。很高兴你问。让我们坐下来做一个小小的思想实验。

  What happens if you and your best friendindependentlyand separatelyconduct the same petition campaign? Let’s say it’s for the “Free the Hamsters” cause.

  如果你和独立和分开你最好的朋友进行同样的请愿运动,会发生什么?假设这是出于“释放仓鼠”的原因。

  Let's say you conduct it in an identical sequence across the same suburb, but come up with different sets of signatures on the petition. Which version of the signed petition is the “source of truth”?

  假设您在同一郊区以相同的顺序进行操作,但在请愿书上提出了不同的签名集。签署的请愿书的哪个版本是“真理的来源”?

  You would need to trace back your separate trails, one signature at a time, to locate thelastdiscrepancy. And then you'd have to work further back to identify the first result that diverged between your signature sheets. Prior to that root divergence, all other signatures on the two lists should match up.

  您需要追溯单独的踪迹,一次签名一个,以找到最后一个差异。然后,您必须进一步进行工作,以找出在签名表之间出现分歧的第一个结果。在该根差异之前,两个列表上的所有其他签名都应匹配。

  You then know that prior to that divergence. Both lists are in accord, so those signatures represent the minimum number of people who signed to support freeing the hamsters.

  然后,您会在出现分歧之前知道这一点。这两个列表是一致的,所以这些签名代表支持释放仓鼠的最少签名人数。

  While that may work well for hamsters and small suburban surveys, it doesn’t work so well in the digital world. Or voting, banking, financial transactions, transferring land title, discharging contractual obligations etc. You need independent and “trusted third parties” to verify a chain of events, and solemnly reassure you that the "chain of custody" was unbroken.

  尽管这对于仓鼠和郊区的小型调查可能效果很好,但在数字世界中效果并不理想。或表决,银行业务,金融交易,土地所有权转让,履行合同义务等。您需要独立且“受信任的第三方”来验证一系列事件,并郑重地向您保证“监管链”没有中断。

  A "chain of custody" can sometimes also be called the "provenance" – they both mean the same thing: the sequence of historical events concerning the data in question.

  有时也可以将“监管链”称为“出处”-它们都具有相同的含义:有关数据的历史事件序列。

  That’s why you have governments having the final say on your identity, and votes need to be physically counted and recounted by hundreds of volunteers, and clerks in dingy offices maintain ledgers and certificates to confirm whether or not you own your farm/white picket-fenced bungalow.
