📜 [專欄新文章] 2021 區塊鏈開發入門
✍️ Johnson Chen
📥 歡迎投稿： https://medium.com/taipei-ethereum-meetup #徵技術分享文 #使用心得 #教學文 #medium

在我大學的時候，除了學習網頁前端之外，因為課程報告的需要接觸到以太坊(Ethereum)，於是開始學寫智能合約，包括它使用的程式語言 solidity。

工作以後鮮少再碰以太坊的相關技術，直到最近想重新把以太坊學起來，故而決定寫這篇文章，讓初次接觸區塊鏈與智能合約的人更好地進入開發者的世界。這篇文章不只面向開發者，同時也希望能夠給對區塊鏈有興趣的人，指引一條清晰的學習路線。

關於區塊鏈

區塊鏈會被廣為人知，無非是因為虛擬貨幣的出現，而虛擬貨幣的鼻祖就是比特幣。在比特幣出現以前，沒有一個能夠在全球網路上通用的數位貨幣；在比特幣出現之後，才真的實現了數位化的貨幣，能夠在全球網路上流通。

這樣的技術性突破，blockchain 的名字從比特幣白皮書中被萃取出來，而這項技術也被更多人拿去做研發以及創新。

區塊鏈這項技術的特性可以簡單概括為兩點：去中心化(decentralized)與不可竄改(immutable)。去中心化有程度上的差別，在公共網路上由世界各地的節點共同維護的區塊鏈，去中心化程度較高；相較之下，私人企業開發由特定節點來驗證交易的區塊鏈，去中心化程度較低。

為什麼是以太坊？

這年頭區塊鏈三個字大行其道，大部分都是為區塊鏈而區塊鏈的商業炒作。容許我獨斷地說，以太坊才是區塊鏈應用的大門。

以太坊由全球最大的區塊鏈社群組成，提供一個去中心化的虛擬機器（Ethereum Virtual Machine）來處理「智能合約」，它是一個公共的區塊鏈平台，逛逛以太坊的官網吧！

智能合約

在以太坊區塊鏈中有所謂的智能合約，智能合約能夠部屬到以太坊區塊鏈上，合約即程式碼，放到區塊鏈上就不能再更新，只能執行合約上的程式，持有以太幣的人能夠與合約進行交易。把智能合約想像成是一台自動販賣機，把錢(以太幣)投進去，飲料會掉出來(合約上的程式會被執行)。

在現實生活中，簽訂合約的雙方認為合約有效而且可以被信任，是因為有國家法律來保障，違反合約可能會受到法律制裁；而用以太幣與智能合約互動，認為智能合約可以被信任，是因為智能合約的不可竄改性 — 以太坊虛擬機會毫無偏袒、完全中立、冰冷不帶任何感情地執行智能合約上已經寫好的程式碼。

建立在智能合約之上的虛擬貨幣

事實上，以太坊擴大了區塊鏈這項技術的應用層面。回頭想想，比特幣來自區塊鏈技術，某個人若想打造一款同比特幣一樣的虛擬貨幣，就得模仿比特幣去建造一個自己的虛擬貨幣區塊鏈，一個區塊鏈網路要能夠有效運作並非易事，還需要節點、需要靠人挖礦去驗證交易。此時，若使用以太坊的智能合約，撰寫虛擬貨幣需要的程式碼，將合約部屬到以太坊區塊鏈上，叮咚！他就可以發行自己的虛擬貨幣，根本不必再去建造底層的區塊鏈，也不用想挖不挖礦了。

此時會發現以太坊就像是一個區塊鏈平台，你不需要親手打造區塊鏈網路，即可享有區塊鏈去中心化與不可竄改的特性。與其他智能合約的開發者共同使用以太坊虛擬機 EVM(Ethereum Virtual Machine)，在 EVM 上部屬無上限個智能合約。

以太坊是一項基礎建設，底層區塊鏈幫你架設好，開發者便有更多時間去發想應用到網頁、手機、或物連網設備上，以下是一段簡單的智能合約，該合約創造了一個虛擬貨幣簡稱 MAT…

直接進入開發領域 — 線上編輯器 Remix

Remix 是開發智能合約的線上編輯器，進入Remix官網，點選 Create New File 以後，把上方程式碼複製貼上。在左側欄位中有 solidity compiler 的選項，確認一下左側欄第一列顯示的版本，調成 0.7.0 (上方程式碼使用的版本)，就可以按下下方 compile 的按鈕，將智能合約「編譯」成 bytecode（給機器讀的語言）。

接著我們要部屬合約到區塊鏈上，首先到左側欄位點選 DEPLOY & RUN TRANSACTIONS 的選項，可以看到環境是 javascript VM，這是指現在要部屬到的測試用虛擬機。按下下方的按鈕 Deploy 即可將合約「部屬」到 javascript VM 上。成功部屬後，你會發現 ACCOUNT 所持有的以太幣，從 100 變成 99.9999…，我們得知部屬智能合約需要花費一點點以太幣。

左側下方會有 Deployed Contracts，點開來就會列出合約上可供呼叫的函式，點那些函式就能與剛剛部屬上去的智能合約進行互動了。

有些函式呼叫會引發交易，所以需要以太幣，有些則不用。在 ACCOUNT 的地方可以展開來，它提供許多的地址 (address)，也就是錢包，每個錢包裡面預設給你 100 顆以太幣，試著用那些地址去操作智能合約，你就能慢慢體會什麼是建立在以太坊之上的虛擬貨幣了。

真正的開發者世界

實際上開發智能合約只能算是以太坊開發的其中一部分，其他包括以太坊區塊鏈擴容方案、節點驗證等等又是另一個開發領域了，那部份我就沒有研究太多。而智能合約的開發是比較接近應用層面的，透過網頁前端或手機應用程式，與智能合約進行互動，稱作 Dapp(Decentralized App) 的開發，也象徵著網際網路走向 web3.0 的時代。

學習 solidity 語言，除了看硬生生的官方文件之外，我推薦去玩cryptozombies，我本身就是從這款網頁遊戲中學習這門語言，聽說是連小孩子都能輕易學習的教材。

除了學 solidity 之外，網路上還有很多方便的開發工具，開發者主要是運用這些工具做測試、自動化部屬、串接前端等等。許多網路上的教學文章會使用 Truffle + Ganache + web3.js 來建置開發環境。但我在這裡推薦另一款開發環境的架構，如果是新手直接從 hardhat 開始也是非常適合的，hardhat 的教學文章寫得清楚完整，本篇文章使用的程式碼也是從 hardhat-hackathon-boilerplate 這個專案而來。hardhat 使用的開發環境是 Waffle + Hardhat + ethers，它幫你把開發環境處理的簡單又舒服，讓開發者可以專注在開發智能合約上。

OpenZeppelin 是很有名的智能合約套件庫，開發時可以引入它的智能合約。智能合約很講究安全性，稍微沒寫好就可能被駭客鑽漏洞，虛擬貨幣就被盜走了！OpenZeppelin 提供的 SafeMath 很常被引入到專案，對新手來說看 OpenZeppelin 的合約也是很好的學習管道。此外，官方也建了一個學習網站ethernaut，主要在教導如何寫出安全性夠強的智能合約，可惜網站在我寫這篇文章的時間一直處於維修不能用的狀態。

最後再介紹一款實際上線的智能合約專案：Argent。它是一款運用智能合約來做虛擬貨幣錢包的公司，除了使用他們的錢包之外，也可以看看他們的智能合約是怎麼寫的，感受一下專業的程式碼架構與寫法。

小結

這篇文章希望能幫助到想了解區塊鏈這項技術的人，同時也想呈現一個智能合約的開發生態系，你大可以不必花太多力氣去了解密碼學、挖礦、節點、共識機制等等五花八門的專有名詞；反之，你可以專注在智能合約的開發，或回到本質去思考去中心化的用意、以及為什麼不可竄改的特性那麼重要。

智能合約除了做虛擬貨幣之外，也能夠做投票系統，原本以貨幣為起始點的區塊鏈技術，是智能合約的出現擴大了區塊鏈更具彈性的用途，這圈子需要更多的開發者來探勘這片新大陸。

尤其鼓勵人文社會科學的人才，無論是哲學、政治、經濟、法律或社會等各方領域，試著撇開人工智慧將主導未來社會的發展路線，與之截然不同的另一種形式：人類社會能否依靠科技的力量，促成彼此之間的合作，創造更有效率的市場、更公平的治理方式？

📜 [專欄新文章] 2019 台北以太坊社群回顧
✍️ 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

很快地，2019 年過去了，台北以太坊社群（TEM）也滿 3 歲了，過去一年，TEM 完成了許多重大的里程碑：

舉辦台灣最大的區塊鏈技術研討會 Crosslink

主持台灣開源界最大的研討會 COSCUP 的區塊鏈議程

參加世界最大的區塊鏈技術研討會 DEVCON

Medium 專欄累積 30+ 篇優質文章

Youtube 頻道累積 50+ 個技術演講

在這篇文章中，我們首先來審視 2019 年以太坊取得重大進展的技術：以太坊2.0與零知識證明，接著再回顧 TEM 於 2019 的優質專欄文章。

*本文由 Juin Chiu 與 Chih-Cheng Liang 共同整理

以太坊重大進展

以太坊2.0的信標鏈

對一般大眾最重要最能吸收的事情大概是 Eth2.0 的信標鏈有測試網路了。透過儀表板網站 www.beaconcha.in 可以看見 Prysmatic Labs 團隊的測試網路的動態。細節很多，但本文就只談這張圖最上面有出現的東西。

在 Eth2.0 沒有挖礦和礦工了，取而代之的是抵押以太幣的驗證者（Validator）來成為資料的寫入者。因此也沒有「區塊時間」這個詞了，新協定以 12 秒為一個「時段」（Slot），信標鏈隨機分配驗證者在指定的時間點產出區塊。在 32 個時段的時間，稱為一個「時期」（Epoch），約 6.4 分鐘，信標鏈會處理驗證者的賞、罰、進、出。在儀表板的左上角可以看到 Epoch 與 Slot 的數字，代表距離最早最古老的區塊多久了。

要怎麼成為驗證者呢？首先要在以太坊 1.0 主網路的抵押合約上，送出一筆交易（在信標鏈測試網路則是送到 Goerli 測試網路）。這筆交易會註冊驗證者的公鑰，並且存入押金（在正式網路是 32 ETH ，測試網路則是 3.2 ETH）。送完之後就排隊等待信標鏈激活驗證者，驗證者就需要開始執行信標鏈分配的任務了。在畫面中間可以看到左邊是 27539 個活躍的驗證者，右邊則是有 4623 個排隊進入的。

在這種基於押金的網路，系統的威脅來自於攻擊者買通大量驗證者，送出矛盾訊息，致使於系統不同節點無法取得共識，鏈資料不可挽回的分叉為兩條。因此系統累積的總押金越多，代表攻擊者成本越高。畫面最右上角左邊即為總押金，右邊為平均一個驗證者的餘額。

假期間和親朋好友一起跑一個驗證者節點，是個活絡氣氛的好活動。要做到這件事，目前 Prysm 客戶端有最友善的介面，請點 連結。程式也用 Docker 包好了，免煩惱安裝。

也記得 Eth2.0 協定有 9 個團隊 用不同程式語言實作。例如：有 Python 語言的客戶端 Trinity ，以及 Rust 語言客戶端 Lighthouse。基本上不用擔心找不到自己喜歡的程式語言的實作。

零知識證明

2019 年，零知識證明的理論與應用也突飛猛進，Kimi Wu 剛好寫了一篇很棒的文獻調查。

前年底提出的 zk rollup，目前由 Matter Labs 在開發，Matter Labs更在上個月（2019/12）發表了 ZK Sync，解決了因為產生證明（proof）而延伸的延遲問題。

此外 Iden3 跟 ConsenSys 也有 zk rollup 的專案。在以太坊研究論壇有基於 zk rollup 的一個提案，是可以達到 匿名性的 zk rollup。

Semaphore是一個基於零知識證明的一個訊號系統，發送者可以不揭露身份的狀況下廣播任何訊息(an arbitrary string)。 Semaphorejs 延續 Semaphore 的核心概念，並將整個概念更加完整化，從前端網頁到後端服務。

這兩年才發表的 zk-STARKs，也在去年年初跟 0x 合作，推出基於 zk-STARKs 的 去中心化交易所。

在技術上，去年下半年有新的論文，使用 DARK compiler 可以讓 SNARKs 達到公開性（Transparent）。還有 MARLIN, SONIC, PLONK 等可通用且可更新的可信設定（trusted setup）。STARKs 的 FRI 驗證方式也默默地跟 SNARKs 做結合。（東西越來越多，根本看不完 QQ）

零知識證明在區塊鏈的重要用途就是「擴展」和「隱私」。技術上的進展，一般可以觀察證明方產出證明的時間、證明的資料大小、驗證方驗證的時間、需不需要可信設定、可信設定有什麼限制、以及抵抗量子電腦的能力。
