🌏 ในโลกของการเขียนโปรแกรมมันก็มีภาษามากมายเกิดขึ้นมา ซึ่งในแต่ละภาษาก็มีความสามารถที่แตกต่างกัน ขึ้นอยู่กับว่าเราจะประยุกต์ใช้กับงานแบบไหน และมีอีกหนึ่งภาษาที่มาแรงมากในหมู่ Data Science ซึ่งบางคนอาจจะยังไม่รู้จัก ซึ่งภาษาที่ว่าคือ...ภาษา R นั่นเอง !
.
และวันนี้แอดจะพาเพื่อน ๆ ทุกคนมาทำความรู้จักกับภาษา R มันคืออะไร ? แล้วใช้ทำอะไรได้บ้าง ? หาพร้อมแล้วไปดูกันเลย !! 🔥
.
🤔 ภาษา R คืออะไร ?
.
ภาษา R เป็นภาษาในการพัฒนาโปรแกรมแบบ Open-Source ใช้งานได้ทุกแพลตฟอร์ม ไม่ว่าจะเป็น Windows, Linux และ macOS เรียนรู้ได้ง่ายไม่แพ้ภาษาอื่น ๆ มีความหยืดหยุ่นสูง เหมาะสำหรับงานด้าน Machine Learning สถิติ และการวิเคราะห์ข้อมูล
.
เป็นอีกหนึ่งภาษาที่แพร่หลายในหมู่ Data Science มี Community และอัตราการเติบโตที่สูงขึ้นเรื่อย ๆ
.
📄 ทำไมถึงต้องใช้ภาษา R ?
.
นอกจากภาษา Python แล้ว ภาษา R ก็เป็นอีกหนึ่งภาษาที่ใช้พัฒนา Machine Learning สถิติ และการวิเคราะห์ข้อมูล สามารถสร้าง Objects, Functions, และ Packages ได้ง่าย ๆ แถมยังมี Learning Curve น้อยกว่า Python มี Syntax ที่เข้าใจง่าย ใช้เวลาแปบเดียวก็เขียนได้แล้ว !
.
ภาษา R ยังสามารถใช้งานร่วมกับภาษาอื่น ๆ ได้ เช่น Python, Java, และ C++ มีสูตรทางคณิตศาสตร์มาให้ ทำให้ประมวลผล และจัดการข้อมูลได้ง่าย แถมยังสามารถใช้งานร่วมกับเครื่องมือวิเคราะห์ข้อมูลได้อีกด้วย
.
แต่ภาษา R ก็ยังมีข้อจำกัดในเรื่องความปลอดภัย จึงไม่เหมาะไปใช้ทำเว็บแอปพลิเคชันนั่นเอง
.
✨ มาเริ่มต้น Hello World กันเลย !!
.
ภาษา R นั้นก็คล้าย ๆ กับภาษาอื่นที่ใช้กันอย่างแพร่หลาย ส่วน IDE ที่นิยมใช้กัน เช่น R Studio, Rattle, Tinn-R เป็นต้น บันทึกไฟล์ที่มีนามสกุล .r
.
cat("Hello World")
.
นอกจากนี้ ยังมีฟังก์ชันที่ช่วยในการคำนวณทางสถิติอีกมากมาย สามารถศึกษาเพิ่มเติมได้ในลิงค์ด้านล่างเลย !! 👇
💥 https://www.tutorialspoint.com/r/index.htm

🔧 ใช้ทำอะไรได้บ้าง ?
.
🔹 Data Science - มีฟังก์ชันมากมายที่เกี่ยวข้องกับงานด้านสถิติ แถมยังมีการเตรียมสภาพแวดล้อมให้เหมาะกับการคำนวณและการออกแบบทางสถิติ
.
🔹 Data Analyst - ช่วยในการนำเข้าและส่งออกข้อมูลในรูปแบบต่าง ๆ ช่วยในการคำนวณและวิเคราะห์ข้อมูลทางสถิติ
.
🔹 Data Visualization - มีฟังก์ชันที่ช่วยในการคำนวณ หากใช้ร่วมกับ IDE สามารถแสดงรูปแบบกราฟได้ตามต้องการ
.
🔹 Machine Learning - รองรับการประมวลผลโมเดลในงานด้าน Machine Learning เป็นอีกหนึ่งภาษาที่ใช้ในงานด้านนี้ไม่แพ้ Python เลยทีเดียว !
.
นอกจากนี้ก็มีบริษัทใหญ่ ๆ อย่างเช่น Google, Facebook, Bing, Twitter, และ Accenture ใช้ภาษา R ในการวิเคราะห์ข้อมูลและทำงานด้านสถิติเช่นกัน
.
เพื่อน ๆ ก็พอจะรู้จักเจ้าภาษา R กันคร่าว ๆ แล้วเนอะ !! ไว้โอกาสหน้าแอดจะหาโปรเจกต์ที่พัฒนาด้วยภาษา R มาแชร์ให้กับเพื่อน ๆ ได้ดูกัน รอติดตามเลย ~~
.
หากชอบ อย่าลืมกดไลก์ กดแชร์ เพื่อเป็นกำลังใจให้กับพวกเราด้วยน้าาาา ❤️

📜 [專欄新文章] Optimistic Rollup 就這樣用（1）

✍️ Juin Chiu

📥 歡迎投稿： https://medium.com/taipei-ethereum-meetup #徵技術分享文 #使用心得 #教學文 #medium

ERC20 的入金、轉帳與出金

TL;DR

本文會跳過 Optimistic Rollup 的介紹而直接實際演示，關於 Optimistic Rollup 的概念與設計原理我將在日後另撰文說明，有興趣的讀者可以先參考下列三篇文章（由淺入深）：1. OVM Deep Dive 2. (Almost) Everything you need to know about Optimistic Rollup 3. How does Optimism’s Rollup really work?

本文將演示一個 Optimism Rollup 範例，程式碼在這裡。

本演示大量參考了以下這兩個官方範例：optimism-tutorial、l1-l2-deposit-withdrawal。

環境設置

Git

Node.js

Yarn

Docker

Docker-compose

筆者沒有碰到環境相容問題，但是建議都升到最新版本， Node.js 使用 v16.1.0 或以上版本

Optimism 服務啟動

有關 Optimisim 的所有服務，都包裝在 Optimism 這個超大專案當中了，直接使用原始碼進行組建：

$ git clone git@github.com:ethereum-optimism/optimism.git$ cd optimism$ yarn$ yarn build

組建完成後，就可以在本機啟動服務了：

$ cd ops$ docker-compose build$ docker-compose up

這個指令會啟動數個服務，包括：

L1 Ethereum Node (EVM)

L2 Ethereum Node (OVM)

Batch Submitter

Data Transport Layer

Deployer

Relayer

Verifier

Deployer 服務中的一個參數要特別注意： FRAUD_PROOF_WINDOW_SECONDS，這個就是 Optimistic Rollup 的挑戰期，代表使用者出金（Withdraw）需等候的時長。在本篇演示中預設為 0 秒。

如果有需要重啟，記得把整個 Docker Volume 也清乾淨，例如： docker-compose down -v

Optimism 整合測試

在繼續接下來的演示之前，我們需要先確認 Optimism 是否有順利啟動，特別是 Relayer 是否運作正常，因此我們需要先進行整合測試：

$ cd optimism/integration-tests$ yarn build:integration$ yarn test:integration

確保 L1 <--> L2 Communication 相關測試通過後再繼續執行接下來的演示內容。

啟動服務及部署合約需要花費一些時間，運行一段時間（約 120 秒）之後再執行測試，如果測試結果全部皆為 Fail，可能是 Optimism 尚未啟動完成，再等待一段時間即可。

ERC20 合約部署

Optimism 啟動成功並且完成整合測試後，接下來進行 ERC20 合約的部署。筆者已將合約及部署腳本放在 optimistic-rollup-example-erc20 這個專案中：

$ git clone git@github.com:ethereum-optimism/optimistic-rollup-example-erc20.git$ cd optimistic-rollup-example-erc20$ yarn install$ yarn compile

接下來我們需要部署以下合約：

ERC20，部署於 L1

L2DepositedEERC20，部署於 L2

OVM_L1ERC20Gateway，部署於 L1

其中，ERC20 與 L2DepositedERC20 是由上面的範例專案編譯的，可以直接在範例專案中直接取得 ABI；而 OVM_L1ERC20Gateway 則是由 Optimism 編譯的，屬於 Optimistic Rollup 協定的一部分，無法直接在範例專案中取得 ABI。

因此在部署以上三個合約前，我們需先手動將 OVM_L1ERC20Gateway 編譯後的生成品 （Artifacts）——即 ABI，複製到此專案中：

$ cp -r ~/projects/optimism/packages/contracts/artifacts/contracts/optimistic-ethereum/OVM/bridge/tokens/OVM_L1ERC20Gateway.sol ~/projects/optimistic-rollup-example-erc20/artifacts/contracts/

OVM_L1ERC20Gateway 只部署在 L1 上，顧名思義它就是 L1 <=> L2 的「門戶」，提供 Deposit / Withdraw 兩個基本功能，使用者必須透過這個合約來進出 L2。

雖然 OVM_L1ERC20Gateway 是 Optimistic Rollup 官方提供的合約。但是開發者也可以依需求自行設計自己的「門戶」。

接下來，我們直接用腳本進行部署：

$ node ./deploy.jsDeploying L1 ERC20...Deploying L1 ERC20...L1 ERC20 Contract Address: 0x1429859428C0aBc9C2C47C8Ee9FBaf82cFA0F20fDeploying L2 ERC20...L2 ERC20 Contract Address: 0x67d269191c92Caf3cD7723F116c85e6E9bf55933Deploying L1 ERC20 Gateway...L1 ERC20 Gateway Contract Address: 0xB0D4afd8879eD9F52b28595d31B441D079B2Ca07Initializing L2 ERC20...

ERC20 入金、轉帳與出金

ERC20 入金（L1 => L2）

目前餘額：

在合約部署完成後，Deployer 是目前唯一有資金的帳戶，接下來我們就進行入金（Deposit），將 Deployer 的資金從 L1 搬到 L2。

首先，進入 ETH（L1） 的 Console：

$ npx hardhat console --network ethWelcome to Node.js v16.1.0.Type ".help" for more information.>

取得 Deployer / User 帳戶：

// In Hardhat ETH Console

> let accounts = await ethers.getSigners()> let deployer = accounts[0]> let user = accounts[1]

取得 ERC20 及 OVM_L1ERC20Gateway 合約物件，合約地址可以從部署訊息中取得：

// In Hardhat ETH Console

> let ERC20_abi = await artifacts.readArtifact("ERC20").then(c => c.abi)> let ERC20 = new ethers.Contract("0x1429859428C0aBc9C2C47C8Ee9FBaf82cFA0F20f", ERC20_abi)> let Gateway_abi = await artifacts.readArtifact("OVM_L1ERC20Gateway").then(c => c.abi)> let Gateway = new ethers.Contract("0xB0D4afd8879eD9F52b28595d31B441D079B2Ca07", Gateway_abi)

先授權 OVM_L1ERC20Gateway 花費 ERC20：

// In Hardhat ETH Console

> await ERC20.connect(deployer).approve("0xB0D4afd8879eD9F52b28595d31B441D079B2Ca07", 10000)> await ERC20.connect(user).approve("0xB0D4afd8879eD9F52b28595d31B441D079B2Ca07", 10000)

注意：Deployer 及 User 都需要對 OVM_L1ERC20Gateway 進行授權，否則在接下來的出金步驟時 Relayer 會出錯

接著，在 OVM_L1ERC20Gateway 合約呼叫 Deposit：

// In Hardhat ETH Console

> await Gateway.connect(deployer).deposit(1000)

我們可以到 Optimism (L2) 的 Console 確認入金是否成功：

$ npx hardhat console --network optimismWelcome to Node.js v16.1.0.Type ".help" for more information.>

取得 Deployer / User 帳戶：

// In Hardhat Optimism Console

> let accounts = await ethers.getSigners()> let deployer = accounts[0]> let user = accounts[1]

取得 L2DepositedERC20 合約物件，合約地址可以從部署訊息中取得：

// In Hardhat Optimism Console

> let L2ERC20_abi = await artifacts.readArtifact("L2DepositedERC20").then(c => c.abi)> let L2DepositedERC20 = new ethers.Contract("0x67d269191c92Caf3cD7723F116c85e6E9bf55933", L2ERC20_abi)

確認入金是否成功：

// In Hardhat Optimism Console

> await L2DepositedERC20.connect(deployer).balanceOf(deployer.address)BigNumber { _hex: '0x03E8', _isBigNumber: true } // 1000

ERC20 轉帳（L2 <=> L2）

完成以上步驟後，目前的餘額如下：

接下來，我們在 L2 從 Deployer 轉移一部分資金給 User：

// In Hardhat Optimism Console

> await L2DepositedERC20.connect(user).balanceOf(user.address)BigNumber { _hex: '0x00', _isBigNumber: true } // 0> await L2DepositedERC20.connect(deployer).transfer(user.address, 1000){ hash: "..." ...}> await L2DepositedERC20.connect(wallet_1).balanceOf(user.address)BigNumber { _hex: '0x03E8', _isBigNumber: true } // 1000

ERC20 出金（L2 => L1）

完成以上步驟後，目前的餘額如下：

接下來，我們用 User 帳戶提領資金，在 L2DepositedERC20 合約呼叫 Withdraw：

// In Hardhat Optimism Console

> await L2DepositedERC20.connect(user).withdraw(1000){ hash: "..." ...}> await L2DepositedERC20.connect(user).balanceOf(user.address)BigNumber { _hex: '0x00', _isBigNumber: true }

最後，檢查在 L1 是否提領成功：

// In Hardhat ETH Console

> await ERC20.connect(user).balanceOf(user.address)BigNumber { _hex: '0x03E8', _isBigNumber: true } // 1000

由於挑戰期為 0 秒，因此提領幾乎無需等待時間，頂多只需數秒鐘

做完上述所有操作，餘額應該如下：

總結

本文演示了：

Optimistic Rollup 相關服務的本機部署

ERC20 L1 => L2 的入金（Deposit）

ERC20 L2 帳戶之間轉帳（Transfer）

ERC20 L2 => L1 的出金（Withdraw）

筆者未來將繼續擴充此系列的教學內容，例如 ERC721 / ERC1155 的使用方式，敬請期待。
