📜 [專欄新文章] Scaling Ethereum 參賽心得

✍️ Johnson

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

Scaling Ethereum 是一場由 ETHGlobal 所舉辦的線上黑客松，也是我第一次參加與以太坊有關的黑客松活動，這篇文章就來分享一人參賽的過程與心得。

源起

一開始是在 telegram 群組中得知這場比賽的消息，因緣際會之下剛好有人想組隊參賽，於是就在報名截止的前一天一起跟著報名了。

報名的方式除了填一些基本資料外，最特別的是還要 stack 以太幣，也就是要傳送 0.01 顆以太幣給主辦方，規則是必須在比賽的最後，有提交作品的人才能贖回 0.01 顆以太幣，之後看到 meme 頻道有人留言：

When your project is incomplete but you submit to get back stake.

一方面，這確實也會激勵你好好把比賽完成，就算沒做完也要有些成果上去，這也是主辦方秉持的精神，他們認為大家來黑客松相互學習成長，競賽獎金則是其次。

獎金

比賽方式是由 25 個左右的贊助者（sponsor）分別提供獎金，每個 sponsor 都有錄製一段影片，說明怎麼獲得他們的獎金，大部分會要你使用他們開發的工具，或者必須跟 sponsor 在做的研究有關，去實作出創新的作品。可參考：Prizes — Scaling Ethereum

你的專案可以選擇要投入哪個 sponsor 的獎金，一個專案可以投入多個 sponsor 底下，這樣獲獎機會也會比較高。

我選擇的 sponsor 是 zkSync，他們的說明如下：

zkSync is a user-centric zkRollup developed by Matter Labs. It uses zero-knowledge proofs to keep data availability on mainnet to achieve exponentially lower transaction costs. You may have seen us powering projects such as payments and Gitcoin Grants. We are currently rapidly developing zkSync 2.0, which will feature EVM-compatibility in testnet May 2021, soon followed by zkPorter, our new exponential scalability solution.

PrizeszkSync will be awarding their Prizes as follows:
- 1 winner — 4,000 USDC
- 2 winners — 2,000 USDC
- 4 winners — 500 USDC

We encourage builders to utilize zkSync SDK’s, implemented in JavaScript/Typescript and Rust. Prizes will be awarded to projects that make it simpler and easier for non-technical users to use zkSync, other ideas include integrations of current tools such as in Gitcoin Grants and tools for easy mass payments and multi-sigs.

社群互動

這個 hackathon 很棒的地方是他把使用者體驗做的很好。每個人都會有自己的 dashboard 顯示目前專案的進度和一些訊息。

Check-In #1 和 Check-In #2 的階段會要你提供專案的構想，你隨時都可以修改。主辦方會看你提交的資訊，幫助你找到適合的 sponsor，或是給你一些建議，就算是一人參賽也能感受到回饋。

整個賽程期間，社群都是使用 discord 在互動，discord 裡頭有很多頻道，像是基本的大會報告的頻道，或是一些不重要的迷因、閒聊頻道都有。

每個 sponsor 也都有自己的頻道，我就會在 sponsor-zksync 的頻道詢問技術的問題，例如我想問問 zkSync 一些關於專案構想的意見：

Hi there, I want to build a gas fee relayer which make my ERC-20 token transfer without transaction fee, to be more precise, delegating gas payment by another party. I think this is done by GSN https://opengsn.org/ , but maybe it could built on L2 with zkSync? I’m not sure, could somebody give me some advice about this topic?

zkSync 團隊的人回應我：

This is an amazing idea! This can totally be built, as we support batching transactions which can be used for all kinds of creative things such as paying for transaction fees in an erc-20 token. Your idea seems like a combination of that and the gitcoin grants integration. To get started, I suggest you watch the short 10 minute presentation I made on using the SDK and batching. Looking forward to your project!!

在 Check-In #2 的時候，我提交新版的專案構想，有一個欄位是問：「目前專案遇到什麼阻礙？」我的問題應該是被主辦方貼給 zkSync 的團隊，於是 zkSync 的團隊成員就用 discord 私訊我，貼了一些程式碼教我怎麼使用他們的 Javascript SDK，這突如其來的救援也幫了大忙。

除此之外，主辦方每個禮拜都會寄 email 通知一些重要的活動，賽程期間舉辦了四個 Summits 研討會，邀請世界各地有名的以太坊開發者分享議題，主辦方還有一個自己的 TV 網頁，直播所有的線上活動。這些活動都有錄影，可以在 youtube 看到過去所有的演講內容：https://www.youtube.com/c/ETHGlobal/videos

因為我的作品是使用 zkSync 的 Javascript SDK 製作的，好像也只能投稿 zkSync 作為獎金的 sponsor，不過主辦方在最後一個禮拜，也寄 email 告訴我說可以多投稿不同的 sponsors 看看，他依據我的專案構想給我一些適合的 sponsors 作為參考。

不過最後我還是只投稿了 zkSync，有點懶著再看其他 sponsors 的文件，也覺得其他 sponsors 的題目需要花比較大的功夫才能完成，一個人能力有限，就做點簡單的東西就好。

關於我的專案 — Gas Relay Service

在以太坊的世界，每一筆交易都需要額外付一筆交易費，也就是以太坊的 gas fee。

我的專案是讓「收款人」能夠幫「付款人」支付以太坊的手續費。

在黑客松之前，我就想研究「第三方支付手續費」的議題，因此我大部分時間其實都在研究一般的 meta-transactions 是怎麼實作的，有興趣的人可以看看 simple meta-transactions 的原始碼：https://github.com/chnejohnson/simple-meta-transaction

之後我才開始玩 zkSync 的 SDK，並研究怎麼在 Layer 2 實現第三方支付手續費的問題，以下就附上作品連結以及簡單的專案介紹給有興趣的人參考：https://showcase.ethglobal.co/scaling/gas-relay-service-on-zksync

The target is that token sender can choose to find another account to pay for fee. The another account can be (1) the token receiver’s account, (2) sender’s another account, (3) third party’s account.

In this project, I finished the demo, which is the (1) above, that receiver pay gas fee for the sender.

有趣的是，我在研究 meta-transactions 時學到很多智能合約的寫法，結果在最後專案上都沒用到（沒寫到合約的程式），zkSync Javascript SDK 其實很簡單，他們的文件寫得很清楚。最後 Demo 還是用 zkSync 團隊的成品修改來的…XD。

所幸在沒有懂太多技術的前提下完成了這場黑客松的專案，成功贖回了 0.01 顆以太幣。

評審與決選

整個賽程來到最後一個禮拜，主辦方安排兩天的時間進行 Judges，使用 zoom 進行線上研討會，一個人基本上是 7 分鐘，前 4 分鐘播放 Demo 簡報，後三分鐘會有評審問問題。

第一個問題是說：「Demo 中你是使用 zkSync 的錢包網頁去操作，那實際上你做得部分是什麼？」

我就回答我在他們的網頁上加了一顆按鈕，使用他們的 SDK 做出 gas relay 的功能，還有一個後端的 server 去作 relay。

第二個問題大概是問：「什麼樣的情境下會需要由 receiver 幫 sender 支付 gas fee？」

我的回答是，在一般超商購物的情境，消費者通常只支付商品的價格，不會支付額外的交易費，我認為以太坊的手續費應該屬於軟體的營運成本，由賣方支付比較適合。那如果賣方希望手續費的成本是由消費者承擔，可以直接調高商品的價格。

當然，我英文講得零零落落，希望評審有聽懂就是了…

最後一場直播就是 Finale 決選，主辦方選出十二個隊伍，公開再 Demo 一次，以及提供線上觀眾詢問問題，至此整個賽程就差不多進入尾聲。

決選後的不久，主辦方就公布了這次有獲得獎金的隊伍，幸運拿到了 zkSync 頒發的小獎～

zkSync — Matter Labs

- Zeneth — 2000 USDC
- ZeroSwap — 1500 USDC
- Kangaroo — 500 USDC
- Gas Relay Service — 500 USDC

後記

這次的參賽隊伍中，Zeneth 跟我的主題非常相似：
Zeneth — Use Flashbots to enable arbitrary meta-transactions so EOAs can enter L2s without ETH

另一個我覺得有趣的專案是 Alexandria：
Alexandria — A dApp using STARKs to verify aspects of your identity without revealing more than you should

沒想到主辦方 ETHGlobal 下個月又要再舉辦一場黑客松，有興趣的人可以看看：https://defi.ethglobal.co/ ，這次的主題是 De-Fi。

最後，只要有到 ETHGlobal 的 TV 網頁參加 Summit 研討會的直播，就能夠獲得 POAP 勳章，它就是一個酷東西～😋

Where do you miss going the most? I miss the Santa Monica Pier ? It's one of my favorite places in LA (as you probably know if you watched my birthday vlog heh), but since it's closed to the public rn, I did makeup that reminds me of it! If there's somewhere you miss going, try doing makeup inspired by it and send it to me on Instagram @jessyluxe ? I've had extra free time to go through DMs lately and it makes me happy to see you all playing with makeup too! A lot of you have been practicing your winged liner and I'm so proud seeing your progress ? We're all coming out of quarantine with a sharp wing ?

I posted that I used only drugstore eye products for this look on IG and I think we were all kinda shook ? Drugstore makeup has come so far..I've been discovering a lot of new drugstore favorites lately while playing with makeup in quarantine. Right now, I'm obsessed with the Revlon Micro Gel Eyeliner, it's so tiny!

I'm not going to lie, I've been super stressed lately so I'm trying my best to create relaxing content for those of you feeling the same ??‍♀️ We can get through this together one day at a time ? Let's seek happiness in our everyday lives. I've started to notice and appreciate little things - the way my bed frame glows as the sun sets, the warmth of freshly laundered sheets, mid-day naps and dreams of being back in a functioning world.
One day, we'll get there again.
