# JoTuanBar 揪團吧 (未完待續) ###### tags: `專題題目想法` `2022` > This is a prototype under development. ## 緣起 你精打細算找到團購優惠卻湊不到人數嗎? 你非常喜歡玩桌遊卻找不到玩伴嗎? 你想去戶外探險卻找不到夥伴陪你瘋嗎? 那你可以試試"**揪團吧(JoTuanBar)**",它是一款多元媒合APP,你可以在上面發起或參與各類型的揪團,快速找到適合你的他(們)。 --- ## 應用範圍與情境 1. 每個用戶都可成為系統中的節點 (已由LBRY影音平台證實可行) 2. 註冊後,用戶可發起各類型的揪團 3. 揪團發起審查自動化 4. 用戶可自行建立群組進行後續討論 (群組存續時間會有不同限制) 5. 用戶有等級上的不同 (ex. 像eeclass一樣須完成特定的任務,獲取經驗值來升級) 6. 商談合作夥伴 (提升特定活動的觸擊率) 7. 廣告投放 8. 自發Token回饋機制 9. 用戶可創建公會招集志同道合的夥伴們,更快揪團成功 --- ## 最大特點 * 使用 IPFS 分散式儲存系統,取代傳統的雲端儲存 > ps. 葉羅堯教授有分散式儲存系統的相關專利: [分散式儲存系統之同步刪除方法](https://www.nchc.org.tw/Patent/PatentView/1049?mid=50&page=1) * 構築出可靠的P2P網路 : 越多節點速度越快 * 非對稱式加密確保安全性 : 利用公私鑰加解密 --- ## 技術(待補) ![](https://i.imgur.com/Pr8sgV2.png) 補充新技術: **Blockchain – IPFS 分散式檔案系統** (進階區塊鏈會教到) * 這張圖超讚的~ ![](https://www.samsonhoi.com/wp-content/uploads/2018/11/interplanetary-file-system.png) 以下是從WFH平台搬來的 (移除APP的部分) * 網頁前端 * HTML * CSS * Javascript/JQuery * 網頁後端 * PHP * Ruby * Node.js * Python * GO * 其他 * 網頁框架 * Tailwind CSS * Bootstrap * Laravel * Vue * Angular * AOS * 其他 * 區塊鏈基本知識 * 如何架鏈 ex. 私有鏈、聯盟鏈、公有鏈 * 代幣總量限制 ex. 比特幣總量近似2100萬 * 出塊機制 ex. 難度設置、報酬比例、多久出塊 * 簽章、加密演算法 ex. SHA256 * 共識機制 ex. PoW、PoA、PoS... * 公、私鑰管理 * Solidity -> 智能合約 Smart Contract * 其他 * UI/UX design * Adobe Xd * Adobe Photoshop * Sketch * Figma * React Native * 其他 * DB * MySQL * phpMyAdmin * SQLite * Oracle * MongoDB * Mircrosoft Access * FireBase (功能很多不是只有DB) * 其他 * 各式API串接 * 天氣 * 匯率 * 重要國際新聞 * 其他 **水很深der...** --- ## 問題點(構思中...) * 短時間內做得完嗎? * 如果教授很快同意,可行性是有的 * 自動審查機制? * 利用內部爬蟲或許可以自動抓取到違反社會善良風俗的東西 * 過濾特定敏感詞 * 上傳到 IPFS 後的檔案很難更改吧? * 這點不可否認,依賴適宜的審查機制或可改善,但仍無法避免有更新資訊需求 * 更新資訊要透過重新的廣播、出塊、上鏈來解決,更新時間是未知數 * 商業價值 * 廣告投放會有流量收益 * 用戶等級是一個可以操作的點 * 高等用戶可以預見的是較為活躍、活動參與率高等等... * 社群中,高等用戶會變成一個普通用戶追逐的目標,高等用戶怕等級被超過,而持續保持活躍,形成完整的循環體系 * 升級經驗的獲取 * 觀看合作廠商的廣告 * 拜訪合作廠商的網站 * 每日簽到 * 揪團活動參與 * 擔任節點的回饋等... * 揪團聊天室存續機制 * 在一般情況下,聊天室的存續時間為7天 * 高等使用者則延長聊天室存續時間 * 這樣可以適當釋放系統資源 * 創建公會 * 公會的創建需要使用平台自發Token * 當公會到達一定等級後,需要花費些許Token做為維持費 * 鼓勵用戶踴躍成為節點 * 自發Token回饋機制 * 搭配合作廠商,花一定數量的Token就可以換到商品或服務的折扣 --- ## 分享區 有趣的東西: [picoCTF](https://picoctf.org/) (computer security) 資安入門 >> search the hidden flag > ps. 虛擬機跟Linux很重要,我只有瞄過蠻有趣的,有時間再來嘿。 --- ## 吐槽 嗯,諧音梗爛到有剩... 緣起也太短了吧! 臨時想到der~ 所以我說 IPFS 的實作可行性ㄌㄟ? 我有找到有人用它架分散式blog IPFS 的操作在 where? 真的要做的話,恭喜 command line 會跟你形影不離 要開虛擬機? 有windows跟mac版可以安裝,但怕爆掉先用VM好惹 P2P的節點設置? 萌新一枚啥都不懂 (支語入侵ing) --- ## PPT製作來源 https://steemit.com/ipfs/@samejack/ipfs https://medium.com/wenchin-rolls-around/%E8%A9%A6%E7%8E%A9-ipfs-a69a52abb954 https://crypto-twpro.com/what-is-ipfs/ https://www.hk01.com/%E8%97%9D%E6%96%87/648037/ipfs-%E5%B0%87%E6%9C%83%E5%8F%96%E4%BB%A3%E7%8F%BE%E6%9C%89-http-%E6%9E%B6%E6%A7%8B-%E5%8F%AF%E4%BB%A5%E6%B0%B8%E4%B9%85%E4%BF%9D%E5%AD%98%E5%85%A7%E5%AE%B9%E8%88%87%E6%AA%94%E6%A1%88%E7%9A%84%E6%8A%80%E8%A1%93 https://www.samsonhoi.com/689/blockchain-ipfs-intro --- [TOC]
