【保姆级教程】区块链数据分析工具指南（3）丨SQL语法

今天我们来做一次实操性的复习，使得我们对Dune平台有更多理性上的认识。

首先，我们来复习一下Dune是什么？

Dune是一款强大的区块链数据分析平台，可以为我们提供丰富的数据和图表。

首先我们来创造一个名字为“Web3.0共学营”的仪表盘，具体步骤如下： 

（1）创建一个新的查询

（2）写一个SQL语句

（3）运行

（4）保存

（5）命名

（6）保存名称

以上步骤就是Dune的官网指引。光看不练假把式，下面我们就按照上面的步骤实操一遍。

首先，创建一个新的查询：

第二步就是写一个SQL语句：

第三步运行该SQL语句，效果如下：

第四步到第六步就是保存并命名，我们命名为“Web3.0共学营第一次演示”，可以设为私密，效果如下：

现在，我们亲自操作了一遍，对创建第一个查询做到心中有数了，真棒。

在下面的示例中，我们将创建一个线图来显示2023年以太坊上独特每日活跃用户和被动用户数量。此外，我们格式化轴标签和刻度标签为0，使数字更易读。

创建可视化需要执行以下步骤：

（1）创建新的可视化

（2）选择要创建的可视化类型

（3）选择x轴和y轴的数据源

（4）调整可视化设置

为了展示我们的数据，需要：

（1）创建一个新的仪表板并命名

（2）向仪表板添加可视化图表

（3）调整仪表板的布局

（4）命名并保存该仪表板

到这里，就要恭喜我们自己啦，因为刚刚查询了区块链数据，创建了一个可视化，并在Dune上展示了我们的数据，现在就可以与世界分享我们的仪表板了。

只要有人看，Dune官方就会负责更新这个仪表盘，所以我们不必担心如何保持它的更新。

复习到这里，我们的Dune的初探学习之旅就要暂告一个段落了，接下来就需要带着好奇心结合ChatGPT和Dune的discord官网社区不断自我提升学习和训练吧~

Today we will interpret the "White Paper on Innovation and Development of Beijing Internet 3.0" released on the morning of May 27, and give an in-depth explanation around the basic situation, key technologies and applications, domestic and foreign development, and the development status of Beijing. 

Through vivid examples, combined with professional terms and key knowledge points, we will be more confident to understand the future prospects of Web3.0.

Web 3.0 is the shape of the next generation of the Internet, which will disrupt the Internet as we know it today. 

To better understand Web 3.0, we need to first understand the evolution of the Internet.

In the era of Web1.0, the Internet was just a tool for information transmission, similar to a static display page. 

In the era of Web2.0, the Internet began to gradually develop towards interactivity and sociability, becoming a vibrant platform.

The Internet in the Web 2.0 era has shortcomings in privacy protection and data control, and users need to submit personal information to a centralized platform to use services.

Web 3.0 is the form of the next generation of the Internet. It is a decentralized Internet that is not controlled by any centralized organization. Users can better protect their privacy and data.

Web 3.0 can be compared to the future form of a city. The Internet in the era of Web 1.0 is just a static city with only planned roads and buildings, lacking vitality and vitality. 

The Internet in the era of Web 2.0 is like a vibrant city with a variety of buildings and roads in which people can freely shuttle. 

And Web3.0 is a vibrant city where everyone can participate in construction and planning to build a better future together.

The following are the key technologies and applications of Web3.0, let's take a look:

Blockchain technology is one of the core technologies in Web3.0. 

It is a decentralized database that can be used to build decentralized applications, decentralized identity verification, and smart contracts. 

The biggest feature of blockchain technology is that data cannot be tampered with and forged, because data is encrypted and stored distributed.

Therefore, blockchain technology allows all users' data to be protected and controlled. For example, in the era of Web3.0, we can use blockchain technology to build a decentralized social media platform where users can freely share their content without submitting personal information to a centralized organization in order to use the service.

Decentralized identity verification is another key technology. In the era of Web3.0, we can use decentralized identity verification to replace traditional centralized identity verification methods. 

Traditional methods require users to submit personal information to centralized institutions, which can be easily stolen and abused. 

Decentralized identity verification allows users to control their identity information and use services without submitting personal information to centralized institutions. 

For example, in the era of Web3.0, we can use decentralized identity verification to conduct online voting, which will make the voting process more fair and transparent.

Distributed applications (DApps) are applications based on blockchain technology that can run on decentralized networks. 

DApps allow users to better protect their privacy and data, and can use services without submitting personal information to a centralized authority. 

For example, in the era of Web 3.0, we can use decentralized email services to protect our privacy and data without submitting personal information to a centralized authority.

The key technologies and applications of Web3.0 allow users to better protect their privacy and data, and use services without submitting personal information to a centralized authority. 

In the era of Web3.0, we can expect more privacy protection and data control, as well as more decentralized services and applications. 

We are confident in the future of Web3.0 and actively learn and adapt to the arrival of Web3.0 in order to better achieve our goals and vision.

比特币作为全球最知名的加密货币之一，一直引发着广泛的兴趣和讨论。

然而，对于初次接触比特币的我们来说，阅读比特币的创始文件《比特币白皮书》可能会感到有些困惑。

别担心！本文将以轻松幽默的语言来解读《比特币白皮书》，有助于我们理解比特币的核心概念。

比特币就像是一种数字版的黄金，它可以通过网络进行传输和交换。我们想象自己是一位超级富豪，想把自己的钱从一个地方带到另一个地方，但又不想通过银行或飞机运输。

比特币就像是我们的私人飞行器，可以快速、安全地将我们的财富传送到世界的任何角落。

去中心化：比特币的去中心化特性意味着没有任何中央机构控制比特币的发行和交易，就像没有一个"大佬"能独自控制全世界的糖果供应一样。

假设我们和一群小伙伴在学校门口交换糖果，每个人都要验证交易的真实性，以防有人想作弊。

这样，即使有人企图捣乱，其他人也会识破并制止这种行为，就像小伙伴们一起守护糖果交易的公平性。

区块链：比特币使用区块链技术来记录交易。区块链就像是一个不断增长的账本，每个区块都包含了一批交易记录。每当有新的交易发生时，它们会被添加到一个新的区块中，然后与之前的区块链接在一起，形成一个长长的链条。

比如说，区块链就像是我们的收藏册，每一页都有一些贴纸，每个贴纸都记录了一次交易。

每当我们有新的贴纸时，我们会把它粘在最后一页上，并与前一页链接起来，这样一来，任何人都可以随时查看和验证贴纸的发生顺序和真实性，确保我们的收藏册完整而可靠。

交易安全性和可靠性：比特币通过使用密码学算法来保证交易的安全性和可靠性。每一笔交易都被广播到网络中的节点，然后通过一系列的计算和验证过程，被打包进一个新的区块中。

这个过程称为挖矿，它需要矿工通过解决复杂的数学问题来竞争获得记账的权利。

简单来讲，挖矿就像是参加一个数学比赛，只有第一个解出问题的人才能获得奖励。

这个过程确保了交易的安全性，因为要改变一笔交易的记录，需要掌握超过50%的计算能力，这几乎是不可能的，就像试图在考试中作弊，但却需要控制整个教室的学生们。

交易手续费：比特币的交易过程中是需要支付一定手续费的。手续费的计算方式是根据交易的大小和网络拥堵情况来决定的。当网络拥堵时，手续费会稍微增加，以鼓励矿工优先处理交易。

就像我们去买一杯奶茶，如果是繁忙的时候，可能需要多付点小费才能更快地拿到奶茶，而在冷清的时候，我们就可以省下一些小费了。

比特币的使用范围已经逐渐扩大，越来越多的商家和服务提供商开始接受比特币作为支付方式。

举个例子，想象一下在家里发现了一个超级稀有的玩具，但是却没有现金。幸运的是，卖家接受比特币支付，那么就可以用比特币购买这个玩具，而不用为了它四处奔波。

在全球范围内，很多国家和地区都可以使用比特币进行支付。但是在一些国家，比特币可能面临着法律限制或监管的挑战，所以记得先了解当地的规定哦，不然你可能会像一个探险家，在不同的国家中寻找比特币接受的商家。

通过本文的幽默解读，相信我们对于《比特币白皮书》中关于交易安全性和可靠性、交易手续费以及比特币的使用范围有了更清晰的理解。

比特币就像是一场有趣的冒险，让我们在数字货币世界中尽情探索。

Reading Tip As one of the most well-known cryptocurrencies globally, Bitcoin has always sparked a wide interest and discussion.

However, for those of us who are new to Bitcoin, reading the founding document of Bitcoin, the "Bitcoin White Paper," might be a little confusing.

Don't worry! This article will explain the "Bitcoin White Paper" in easy and humorous language, which will help us understand the core concepts of Bitcoin.

Bitcoin is like a digital version of gold that can be transmitted and exchanged through the network. 

Imagine if we were a super-rich person who wanted to move our money from one place to another but didn't want to transport it through banks or planes. 

Bitcoin is like our private jet that can quickly and safely transport our wealth to any corner of the world.

Decentralization: The decentralization feature of Bitcoin means that no central authority controls the issuance and transaction of Bitcoin, just like no "big shot" can control the candy supply worldwide alone.

Suppose we and a group of friends exchange candy at the school gate, and everyone needs to verify the authenticity of the transaction to prevent cheating.

This way, even if someone tries to disrupt, others will detect and stop this behavior, just like friends guarding the fairness of candy transactions together.

Blockchain: Bitcoin uses blockchain technology to record transactions. The blockchain is like a growing ledger, and each block contains a batch of transaction records. 

Whenever a new transaction occurs, it is added to a new block, then linked to the previous blocks, forming a long chain.

For example, the blockchain is like our collection book, and each page has some stickers, and each sticker records a transaction.

Whenever we have a new sticker, we paste it on the last page and link it with the previous page, so that anyone can view and verify the order and authenticity of the stickers at any time, ensuring that our collection book is complete and reliable.

Transaction Security and Reliability: Bitcoin uses cryptographic algorithms to ensure the security and reliability of transactions. 

Each transaction is broadcast to nodes in the network and then packaged into a new block through a series of calculations and validation processes. 

This process is called mining, which requires miners to compete for the right to bookkeeping by solving complex mathematical problems.

In simple terms, mining is like participating in a math competition, and only the first person to solve the problem can win the prize. 

This process ensures the security of transactions because changing the records of a transaction requires controlling more than 50% of the computing power, which is almost impossible, just like trying to cheat in an exam but needing to control all the students in the classroom.

Transaction Fees: Bitcoin transactions require paying a certain fee. The calculation of fees is determined based on the size of the transaction and network congestion. 

When the network is congested, the fee will increase slightly to encourage miners to prioritize processing transactions. 

It is like when we buy a cup of milk tea, if it is busy, we may need to pay more tips to get the milk tea faster, and when it is quiet, we can save some tips.

The scope of Bitcoin use has gradually expanded, and more and more merchants and service providers have begun to accept Bitcoin as a payment method. 

For example, imagine finding a super-rare toy at home, but having no cash. Luckily, the seller accepts Bitcoin payment, so we can buy this toy with Bitcoin without running around for it.

In many countries and regions worldwide, Bitcoin can be used for payment. 

But in some countries, Bitcoin may face legal restrictions or regulatory challenges, so remember to first understand the local regulations, otherwise, you may be like an explorer looking for merchants accepting Bitcoin in different countries.

Through the humorous interpretation of this article, we believe that we have a clearer understanding of the "Bitcoin White Paper" regarding transaction security and reliability, transaction fees, and the scope of Bitcoin use. Bitcoin is like an exciting adventure that allows us to explore the digital currency world to the fullest.

然而，对于新手来说，了解这个快速发展的领域存在的潜在风险和漏洞至关重要。

本文将探讨DeFi中常见的攻击手段，如币价操纵、利用预言机错误通过抵押借贷变现、做空Defi杠杆和闪电贷治理攻击。

通过了解这些攻击手法并采取谨慎策略，你可以在参与DeFi领域时保护自己并做出明智的决策。

Welcome to the world of decentralized finance (DeFi), where innovative financial opportunities abound.

However, it's important for newcomers to be aware of the potential risks and vulnerabilities that exist within this rapidly evolving landscape.

In this article, we will explore common attack methods in DeFi, such as price manipulation, leveraging oracle errors for collateralized loans, shorting DeFi with leverage, and governance attacks through flash loans.

By understanding these attack vectors and implementing cautious strategies, you can protect yourself and make informed decisions while participating in the DeFi space.

币价操纵是DeFi中常见的攻击手段。举个例子，想象一下一个恶意行为者，他积累了大量某个特定代币。

通过协调的交易行为，他人为地推高价格，制造需求的假象。

一旦价格达到期望的水平，他抛售自己的持仓，导致价格迅速下跌，使毫不知情的投资者蒙受损失。

为了防范这种操纵行为，必须进行彻底的研究，分析市场趋势，并在价格异常波动期间小心进入交易。

Price manipulation is a prevalent attack method in DeFi. 

Let's consider an example: Imagine a malicious actor who accumulates a significant amount of a specific token.

Through coordinated trading actions, they artificially inflate the price to create an illusion of demand.

Once the price reaches a desired level, they sell their holdings, causing a rapid price decline and leaving unsuspecting investors at a loss.

To safeguard against such manipulation, it's crucial to conduct thorough research, analyze market trends, and be cautious when entering trades during periods of suspicious price movements.

DeFi应用程序通常依赖预言机获取现实世界的数据。

然而，这些预言机可能容易受到操纵或错误的影响，攻击者可以利用这一点获利。例如，攻击者可能与预言机勾结提供不准确的数据，从而触发错误的贷款抵押评估。

随后，他们可以获得超估值的贷款或利用智能合约中的漏洞获取比应有的更多资金。

为了降低这种风险，选择可信的预言机，在参与任何抵押借贷交易之前验证数据源的准确性至关重要。

DeFi applications often rely on oracles to fetch real-world data.

However, these oracles can be susceptible to manipulation or errors, which attackers can exploit for their gain. 

For instance, an attacker might collude with an oracle to provide inaccurate data, triggering incorrect loan collateral valuations.

Subsequently, they can obtain loans with overvalued collateral or exploit vulnerabilities in smart contracts to secure more funds than they should.

To mitigate this risk, it's essential to choose trusted oracles and verify the accuracy of data sources before engaging in any collateralized loan transactions.

做空Defi杠杆允许交易者从市场下跌中获利。然而，这种策略也存在风险。

假设一个交易者借入大量特定代币并抛售，预期价格下跌。

如果市场意外上涨，交易者可能面临追加保证金的风险，并被迫以亏损平仓。

在参与做空Defi之前，必须充分了解杠杆机制，建立适当的风险管理策略，并在仔细评估市场情况后决定参与。

Shorting DeFi with leverage allows traders to profit from market downturns. However, this strategy carries risks.

Let's say a trader borrows a significant amount of a particular token and sells it, anticipating a price drop.

If the market unexpectedly rallies, the trader may face a margin call and be forced to close their position at a loss.

It's crucial to thoroughly understand leverage mechanisms, set appropriate risk management strategies, and carefully assess market conditions before engaging in shorting DeFi.

闪电贷是一种短期借贷方式，在DeFi协议中可以被利用进行治理攻击。

攻击者可以发起闪电贷，并利用借到的资金影响协议的治理决策，如对重要提案进行投票。通过策略性地操纵这些决策，他们可以潜在地改变协议的功能或流失资金。

要防范此类攻击，需要保持警惕，积极参与社区治理讨论，以便及时发现和阻止攻击。

Flash loans, a type of short-term borrowing, can be exploited for governance attacks in DeFi protocols.

An attacker can initiate a flash loan and use the borrowed funds to influence protocol governance decisions, such as voting on critical proposals. By strategically manipulating these decisions, they can potentially alter the protocol's functionality or drain funds.

Vigilance and participation in community governance discussions are vital to detecting and preventing such attacks.

新手们了解DeFi中的潜在风险至关重要。通过认识常见的攻击手段，如币价操纵、利用预言机错误、做空Defi杠杆和闪电贷治理攻击，个人可以在DeFi领域谨慎行事。

请记住，进行彻底的研究，实施风险管理策略，并随时了解最佳实践，以保护你的投资并促进一个安全透明的DeFi生态系统的发展。

It's crucial for newcomers to understand the potential risks associated with DeFi. By recognizing common attack methods, such as price manipulation, leveraging oracle errors, shorting DeFi with leverage, and governance attacks through flash loans, individuals can navigate the DeFi landscape with caution.

Remember to conduct thorough research, implement risk management strategies, and stay updated on best practices to protect your investments and contribute to the growth of a secure and transparent DeFi ecosystem.

本文将以通俗易懂的方式介绍区块链的概念、原理和应用，带领你踏上一段奇妙的区块链探索之旅。

This article will introduce the concept, principles, and applications of blockchain in a simple and easy-to-understand manner, taking you on a wonderful journey of exploring the blockchain world.

区块链的六层架构 The Six-Layer Architecture of Blockchain

区块链技术可以被分解为六个层级，每个层级都扮演着不同的角色，共同构成了完整的区块链系统。

这些层级依次是：传输层，数据层（合并为数据传输层），网络层、共识层、激励层，合约层和应用层。

分别对应着L0、L1、L2，而L3是客户端应用层，不符合区块链技术逻辑框架。

The blockchain technology can be decomposed into six layers, each playing a different role and collectively forming a complete blockchain system.

These layers, in order, are the transport layer, network layer（Merged as the Data Transmission Layer），consensus layer, incentive layer, contract layer, and application layer.

They correspond to L0, L1, L2 respectively, while L3 represents the client application layer, which is not part of the logical framework of blockchain technology.

Layer0：数据传输层 Data Transmission Layer

数据传输层负责在区块链网络中传递数据，保证数据的安全性和完整性。

它使用加密技术和分布式存储方式，确保数据在传输过程中不被篡改。

是互联网和硬件连接存在的地方。

The Data Transmission Layer is responsible for transmitting data within the blockchain network, ensuring the security and integrity of the data.

It uses encryption techniques and distributed storage methods to ensure that the data remains unaltered during transmission.

It serves as the connection point between the internet and hardware devices.

这一层的作用如下：

1）区块链可互操作性 Cosmos 创造了一个可互操作的区块链生态系统，实现了区块链相互交互，这得益于其“Tendermint IBC”（区块链间通信协议）。

Blockchain Interoperability: Cosmos has created an interoperable blockchain ecosystem that enables different blockchains to interact with each other, thanks to its "Tendermint IBC" (Inter-Blockchain Communication) protocol.

2）更快、更便宜的跨链交易 使用IBC，POS共识可以实现跨多个链进行交易，导致最终确定时间几乎在瞬间发生。这使得跨链交易所的交易更快、更便宜。

Faster and Cheaper Cross-Chain Transactions: By utilizing IBC, Proof-of-Stake (POS) consensus allows transactions to occur across multiple chains, resulting in near-instant finality. This makes transactions on cross-chain exchanges faster and more cost-effective.

3）开发人员的基础设施 开发人员无需从头开始构建他们的区块链，许多功能都是预先构建的，可以立即实施。

Infrastructure for Developers: Developers don't have to build their blockchains from scratch as many functionalities are pre-built and ready for immediate implementation.

Layer1：链上扩容方案 On-chain scaling solutions

链上扩容方案是指通过对区块链协议本身进行改进，提高网络的吞吐量和交易处理能力。其中包括改进共识算法、区块大小和区块时间等参数。

On-chain scaling solutions refer to improving the throughput and transaction processing capacity of a blockchain network by making modifications to the blockchain protocol itself. This includes enhancing consensus algorithms, block size, block time, and other parameters.

第一层是处理和完成交易的区块链，例如比特币和以太坊。这是共识（PoW、PoS）和区块时间等技术细节的运作地点。

The first layer is the blockchain that handles and finalizes transactions, such as Bitcoin and Ethereum. This is where the technical details of consensus (PoW, PoS) and block time operation take place.

最重要的三个方面是去中心化、安全性和可扩展性，但目前还没有一个区块链能够同时很好地解决这三个问题。

The most important aspects are decentralization, security, and scalability. However, currently, there is no blockchain that can effectively address all three of these issues simultaneously.

** **

Layer2：链下扩容方案 Off-chain scaling solutions

链下扩容方案通过在区块链之外构建第二层协议，实现更高效的交易处理和更低的成本。

例如，闪电网络就是一种链下扩容方案，通过在区块链上开设支付通道，实现快速的微小额交易。

Off-chain scaling solutions involve building second-layer protocols outside the blockchain to achieve more efficient transaction processing and lower costs.

For example, the Lightning Network is an off-chain scaling solution that establishes payment channels on the blockchain to enable fast and low-value transactions.

当你听到零知识汇总（zk rollups）、侧链或任何与加快事务吞吐量有关的事情时，大概率指的都是第 2 层。

When you hear about concepts like zk-rollups, sidechains, or anything related to increasing transaction throughput, it most likely refers to the second layer.

假设您是一名魔法师，拥有一种特殊的能力。您希望向他人证明您拥有这种能力，但又不想透露具体细节。零知识证明就是一种神奇的方法，它可以让您向他人证明某个事实的真实性，却不泄露与该事实相关的任何信息。

Imagine you are a magician with a special ability. You want to prove to others that you possess this ability, but you don't want to reveal the specific details. Zero-knowledge proofs are a magical method that allows you to prove the truth of a fact to others without disclosing any information related to that fact.

Layer3：客户端应用层 Client Application Layer

客户端应用层是用户与区块链系统进行交互的接口，包括钱包应用、智能合约应用和去中心化应用（DApps）。用户可以通过这些应用管理资产、参与投票、执行智能合约等操作。

The Client Application Layer is the interface through which users interact with the blockchain system. It includes wallet applications, smart contract applications, and decentralized applications (DApps). Users can use these applications to manage assets, participate in voting, execute smart contracts, and perform other operations.

区块链的六层架构与四个层级的关系 The relationship between the six-layer architecture and the four hierarchical levels of blockchain

区块链的六层架构和四个层级相互关联，共同构成了一个完整的区块链生态系统。

The six-layer architecture of blockchain is closely related to the four hierarchical levels, together forming a complete blockchain ecosystem.

数据传输层为上层提供了安全可靠的数据传输基础，共识层确保所有节点对数据的一致性，网络层提供了节点之间的通信机制，合约层实现了智能合约的执行，应用层为用户提供了各种区块链应用，用户界面层使用户可以方便地使用区块链服务。

The data transmission layer provides a secure and reliable foundation for data transmission to the upper layers. The consensus layer ensures consistency of data among all nodes. The network layer establishes communication mechanisms between nodes. The contract layer enables the execution of smart contracts. The application layer offers various blockchain applications to users, and the user interface layer facilitates convenient access to blockchain services.

区块链作为一种革命性的技术，正在改变着我们的世界。通过了解区块链的六层架构和四个层级，我们能够更好地理解区块链的工作原理和应用场景。

As a revolutionary technology, blockchain is changing our world. By understanding the six-layer architecture and four hierarchical levels of blockchain, we can better grasp its working principles and application scenarios.
