Blockchain 2.0: An Introduction [Part 1]
|
||||
======
|
||||
|
||||
|
||||
|
||||
### Blockchain 2.0 – The next paradigm of computing
|
||||
|
||||
The **Blockchain** is now easily distinguishable as a transformational technology poised to bring in revolutionary changes in the way people use the internet. The present series of posts will explore the upcoming wave of Blockchain 2.0 based technologies and applications. The Blockchain is here to stay as evidenced by the tremendous interest in it shown by different stakeholders.
|
||||
|
||||
Staying on top of what it is and how it works is paramount to anyone who plans on using the internet for literally anything. Even if all you do is just stare at your friends’ morning breakfast pics on Instagram or looking for the next best clip to watch, you need to know what this technology can do to all of that.
|
||||
|
||||
Even though the basic concept behind the Blockchain was first talked about in academia in the **1990s** , its prominence to being a trending buzzword among netizens is owed to the rise of payment platforms such as **Bitcoins** and **Ethers**.
|
||||
|
||||
Bitcoin started off as a decentralized digital currency. Its advent meant that you could basically pay people over the internet being totally anonymous, safe and secure. What lay beneath the simple financial token system that was bitcoin though was the BLOCKCHAIN. You can think of Bitcoin technology or any cryptocurrency for that matter as being built up from 3 layers. There’s the foundational Blockchain tech that verifies, records and confirms transactions, on top of the foundation rests the protocol, basically, a rule or an online etiquette to honor, record and confirm transactions and of course, on top of it all is the cryptocurrency token commonly called Bitcoin. A token is generated by the Blockchain once a transaction respecting the protocol is recorded on it.
|
||||
|
||||
While most people only saw the top layer, the coins or tokens being representative of what bitcoin really was, few ventured deep enough to understand that financial transactions were just one of many such possibilities that could be accomplished with the help of the Blockchain foundation. These possibilities are now being explored to generate and develop new standards for decentralizing all manners of transactions.
|
||||
|
||||
At its very basic level, the Blockchain can be thought of as an all-encompassing ledger of records and transactions. This in effect means that all kinds of records can theoretically be handled by the Blockchain. Developments in this area will possibly in the future result in all kinds of hard (Such as real estate deeds, physical keys, etc.) and soft intangible assets (Such as identity records, patents, trademarks, reservations etc.) can be encoded as digital assets to be protected and transferred via the blockchain.
|
||||
|
||||
For the uninitiated, transactions on the Blockchain are inherently thought of and designed to be unbiased, permanent records. This is possible because of a **“consensus system”** that is built into the protocol. All transactions are confirmed, vetted and recorded by the participants of the system, in the case of the Bitcoin cryptocurrency platform, this role is taken care of by **miners** and exchanges. This can vary from platform to platform or from blockchain to blockchain. The protocol stack on which the platform is built is by definition supposed to be open-source and free for anyone with the technical know-how to verify. Transparency is woven into the system unlike much of the other platforms that the internet currently runs on.
|
||||
|
||||
Once transactions are recorded and coded into the Blockchain, they will be seen through. Participants are bound to honor their transactions and contracts the way they were originally intended to be executed. The execution itself will be automatically taken care of by the platform since it’s hardcoded into it, unless of course if the original terms forbid it. This resilience of the Blockchain platform toward attempts of tampering with records, permanency of the records etc., are hitherto unheard of for something working over the internet. This is the added layer of trust that is often talked about while supporters of the technology claim its rising significance.
|
||||
|
||||
These features are not recently discovered hidden potentials of the platform, these were envisioned from the start. In a communique, **Satoshi Nakamoto** , the fabled creator(s) of Bitcoin mentioned, **“the design supports a tremendous variety of possible transaction types that I designed years ago… If Bitcoin catches on in a big way, these are things we’ll want to explore in the future… but they all had to be designed at the beginning to make sure they would be possible later.”**. Cementing the fact that these features are designed and baked into the already existing protocols. The key idea being that the decentralized transaction ledger like the functionality of the Blockchain could be used to transfer, deploy and execute all manner of contracts.
|
||||
|
||||
Leading institutions are currently exploring the possibility of re-inventing financial instruments such as stocks, pensions, and derivatives, while governments all over the world are concerned more with the tamper-proof permanent record keeping potential of the Blockchain. Supporters of the platform claim that once development reaches a critical threshold, everything from your hotel key cards to copyrights and patents will from then on be recorded and implemented via the use of Blockchains.
|
||||
|
||||
An almost full list of items and particulars that could theoretically be implemented via a Blockchain model is compiled and maintained on [**this**][1] page by **Ledra Capital**. A thought experiment to actually realize how much of our lives the Blockchain might effect is a daunting task, but a look at that list will reiterate the importance of doing so.
|
||||
|
||||
Now, all of the bureaucratic and commercial uses mentioned above might lead you to believe that a technology such as this will be solely in the domain of Governments and Large private corporations. However, the truth is far from that. Given the fact that the vast potentials of the system make it attractive for such uses, there are other possibilities and features harbored by Blockchains. There are other more intricate concepts related to the technology such as **DApps** , **DAOs** , **DACs** , **DASs** etc., more of which will be covered in depth in this series of articles.
|
||||
|
||||
Basically, development is going on in full swing and its early for anyone to comment on definitions, standards, and capabilities of such Blockchain based systems for a wider roll-out, but the possibilities and its imminent effects are doubtless. There are even talks about Blockchain based smartphones and polling during elections.
|
||||
|
||||
This was just a brief birds-eye view of what the platform is capable of. We’ll look at the distinct possibilities through a series of such detailed posts and articles. Keep an eye out for the [**next post of the series**][2], which will explore how the Blockchain is revolutionizing transactions and contracts.

# 区块链 2.0: 一份介绍 [Part 1]
|
||||
|
||||
|
||||
|
||||
### 区块链 2.0 - 下一个计算范式
|
||||
|
||||
**区块链**现在被认为是一种转型技术，它将为人们使用互联网的方式带来革新。本系列文章将探讨即将到来的基于区块链 2.0 的技术和应用。不同的涉众对它表现出的极大兴趣证明了区块链的存在。
|
||||
|
||||
对于任何打算使用互联网做任何事情的人来说，了解它是什么以及它是如何工作的都是至关重要的。即使你所做的只是盯着 Instagram 上朋友们的早餐照片，或者寻找下一个最好的视频片段，你也需要知道这项技术能对这些提供什么样的帮助。
|
||||
|
||||
尽管区块链的基本概念早在上世纪 90 年代就被学术界提及，但它之所以成为网民热词，要归功于诸如**比特币**和 **Ethers** 等支付平台的崛起。
|
||||
|
||||
比特币最初是一种去中心化的数字货币。它的出现意味着你基本上可以通过互联网进行完全匿名，安全可靠的支付。不过，在比特币这个简单的金融令牌系统背后，是区块链。您可以将比特币技术或任何加密货币看作是 3 层结构。区块链基础技术包括验证、记录和确认交易，在这个基础之上是协议，本质上来讲是一个规则或在线礼仪，用来尊重、记录和确认交易，当然，最重要的是通常被称作比特币的加密货币令牌。一旦记录了协议相关的事务，区块链就会生成令牌。
|
||||
|
||||
虽然大多数人只看到了最顶层，即代表比特币真正含义的硬币或代币，但很少有人敢于深入了解，在区块链基金会的帮助下，金融交易只是众多此类可能性中的一种。目前正在探讨这些可能性，以产生和开发所有去中心化交易方式的新标准。
|
||||
|
||||
在最基本的层次上，区块链可以被认为是一个包含所有记录和交易的账簿。这实际上意味着区块链理论上可以处理所有类型的记录。未来这方面的发展可能会导致各种硬资产(如房地产契约、实物钥匙等)和软无形资产(如身份记录、专利、商标、预约等)被编码为数字资产，通过区块链进行保护和转让。
|
||||
|
||||
对于不熟悉区块链的人来说，区块链上的事务本质上被认为是无偏见的永久记录。这是可能的，因为协议中内置了**共识系统**。所有交易均由系统参与者确认、审核和记录，在比特币加密货币平台中，该角色由**矿商**和交易所负责。这可能因平台而异，也可能因区块链到区块链而异。根据定义，构建该平台的协议栈应该是开放源码的，并且对任何具有技术能力的人都是免费的。与目前互联网上运行的许多其他平台不同，该系统内置了透明度。
|
||||
|
||||
一旦事务被记录并编码到区块链中，它们就会被看穿。参与者有义务按照他们最初打算执行的方式履行他们的交易和合同。除非最初的条款禁止执行，否则执行本身将由平台自动处理，因为它是硬编码的。区块链平台对于试图篡改记录、记录的持久性等方面的恢复能力，在因特网上是闻所未闻的。当这项技术的支持者们宣称其日益重要的意义时，这种能力是经常被提及的附加信任层。
|
||||
|
||||
这些特性并不是最近发现的隐藏的平台潜力，而是从一开始就被设想出来的。公报中，**Satoshi Nakamoto（中本聪）**，传说中的比特币创造者，**“我花了数年的时间来构造一个用来支撑巨大的各种可能事务类型的设计……如果比特币能够流行起来，这些都是我们未来要探索的……但是他们从设计之初，就要确保他们以后可能性。”**。结合这样一个事实，即这些特性被设计并融入到已经存在的协议中。关键的想法是，去中性化的事务分类账(如区块链的功能)可以用于传输、部署和执行各种形式的契约。
|
||||
|
||||
领先机构目前正在探索重新发明股票、养老金和衍生品等金融工具的可能性，而世界各国政府更关注区块链的防篡改和永久性保存记录的潜力。该平台的支持者声称，一旦开发达到一个关键的门槛，从你的酒店钥匙卡到版权和专利，那时起，一切都将通过区块链记录和实现。
|
||||
|
||||
**Ledra Capital**在[**这个**][1]页面上编译并维护了几乎完整的项目和细节列表，这些项目和细节理论上可以通过区块链模型实现。想要真正意识到区块链对我们生活的影响有多大是一项艰巨的任务，但看看这个清单就会重申这么做的重要性。
|
||||
|
||||
现在，上面提到的所有官僚和商业用途可能会让你相信，这样的技术只会出现在政府和大型私营企业领域。然而，事实远非如此。鉴于该系统的巨大潜力使其对此类用途具有吸引力，区块链还具有其他可能性和特性。还有一些与该技术相关的更复杂的概念，如**DApps**、**DAOs**、**DACs**、**DASs**等，本系列文章将深入讨论这些概念。
|
||||
|
||||
基本上，开发正在如火如荼地进行，任何人都还没有来得及对基于区块链的系统的定义、标准和功能进行评论，以便进行更广泛的推广，但是这种可能性及其即将产生的影响无疑是存在的。甚至有人谈到基于区块链的智能手机和选举期间的投票。
|
||||
|
||||
这只是一个简短的鸟瞰平台的能力。我们将通过一系列这样详细的帖子和文章来研究这些不同的可能性。关注[**本系列的下一篇文章**][2]，它将探索区块链是如何革新交易和契约的。
