戈壁說

NFT

放下

鼓勵

擁抱

堅持

創業家精神

我是一個創業家，創業10年了，我在創業第8年的時候獲得了富士康以及幾家外商企業共同投資，運營了一段時間，比較有時間的時候到台大EiMBA進修，進修的第一年，教授就邀請我到台大創意創業中心，指導學生和碩士生有關創新、創業方面的相關事宜。如果說道來到戈壁的體會，先要說到我最喜歡的一句話「像個孩子」，像個孩子般盡情的揮灑、像個孩子般盡情撒野、像個孩子般盡情奔跑。因爲我們生活在都市叢林中，所以我們很難有時間真正把自己的心靈放開的時候，來到戈壁就像小朋友從爬到會走的那一步，他剛剛跨出那一步心中的感受，這句話對我來說非常感動。還有一首最難忘的歌，《怒放的生命》，這幾天時時聽、經常聽，所以我決定回去一定要去KTV裡面好好地練習。接下來，我想講一講這四天我學到了什麼。



我們都一樣渺小，再一起才能偉大

第一天我學到的第一件事就是放下

因爲我的背包實在是太重了，來這邊之前，我什麼都不知道，所以該帶不該帶的東西都帶上了，路途中有人一直叫我放下，這是我來到這邊學到的第一件事。放下就像我們常常講的一句話，你如果握緊你的雙手，握緊你的拳頭，你什麼也得不到，當你張開雙手，天下就是你的。

第二天我學到的是鼓勵

因爲開始有了排名賽，要努力跟上這個大部隊，其實我覺得還是蠻難的，很多時候我一個人走，一個人走的時候，想當起以前當兵的時候，就會唱唱歌，跟著戈友走的時候，就一起聊聊天，非常感覺我們終點的賽事志願者，他陪我一起最後加油，最後我拿到了銀牌，就只差大概三分鐘左右，所以第二天我學到的是鼓勵。

第三天我覺得我學到的是堅持

到了第三天，和其他戈友一樣我也收穫大水泡，除此之外還有腫得像拳頭一樣大的腳踝，所以走起路來格外的辛苦，但是我想到我一個人到達就是整個院校到達，所以我就努力的堅持下去，不斷的堅持到底，沿路的戈友沒有洩氣的話，都是鼓勵的話，所以我覺得第三天非常值得堅持。

到了第四天，我覺得我學到的是擁抱

擁抱大自然，擁抱戈壁，擁抱所有的戈友們，所以我要謝謝我們的領隊、還有一路照顧我飲食起居的志願者、還有所有的戈友們，謝謝大家，我愛你們！

IOTA 這麼好的鏈，但確一直缺乏應用，甚至連發行自己的 Token 以及 NFT 都很難在這條鏈上發行，但最近 Soonaverse 的崛起，很大的程度讓不懂程式的使用者可以像是在公海 OpenSea 中發行一個 NFT ，但老實說還是有進入障礙，所以還是留下懶人包以及筆記。

1.先取得 MetaMask (必要)

MetaMask – Desktop – Welcome to the Soonaverse

2.設定 MetaMask 連結 IOTA

Adding the IOTA EVM Network – Desktop – Welcome to the Soonaverse

Network Name: IOTA EVM

TestnetNew RPC URL: https://evm.wasp.sc.iota.org

Chain ID: 1074

Currency Symbol: IOTA

Block Explorer URL: https://explorer.wasp.sc.iota.org

3. Soonaverse 設定基本資料

Profile – Desktop – Welcome to the Soonaverse

4.下載 IOTA 官方錢包 FireFly

IOTA – 螢火蟲錢包 FireFly Wallet – 雨 (rain.tips)

5.取得 MI 幣

透過幣安購買MITAC幣並且出金到 FireFly 錢包中，我是買最低的金額大約 80 mi 幣，因為等等驗證時候他會還錢給你，所以並不用多錢，只需要最低金額即可。

6.利用 FireFly 驗證 IOTA 地址

https://docs.soonaverse.com/en/all-users-getting-started/verifying-your-iota-wallet

7.建立空間 Space

https://docs.soonaverse.com/en/space-owners-getting-started/building-a-space

https://soonaverse.com/space/0x5fcc5562385e6c2f6b0a5934280e5d11274f8e07/overview

8.建立空間中的勳章和發行NFT勳章

https://soonaverse.com/space/0x5fcc5562385e6c2f6b0a5934280e5d11274f8e07/awards

9.創建 NFT

https://docs.soonaverse.com/en/nft-creators-getting-started/creating-an-nft-collection

10.投票以及勳章(非必要)

https://docs.soonaverse.com/en/space-owners-getting-started/creating-a-proposal

https://docs.soonaverse.com/en/space-owners-getting-started/making-an-award

勳章可以用來設置優惠價格以及贈送 NFT

最近最多人使用的 NFT 平台 OpenSea 也開始支援了 Polygon 鏈，並且發行 NFT 並不用任何的費用，之後有賣出並且成交的交易手續費收取 2.5% 也是相當合理，我想可以大量的使用他來上鏈了，剛好也有疑惑，鏈上的 NFT 一定是需要正正方方的嗎?我手上的3D圖、環景圖可不可以使用，經過測試以及驗證發現都是可以用的，說明如下：

1.建立新的 NFT

2.上傳圖片以及填寫相關資訊

必要資訊有

Image, Video, Audio, or 3D Model (圖片、影片、聲音、3D模型檔)
Name 名稱
Blockchain 區塊鏈

3.選擇區塊鏈

4. NFT 建立完成

5.販賣 NFT

OpenSea 中的 NFT 最低定價是 5 美元，換算台幣和 ETH 的話，建議最低由 0.002 ETH 開始，當然沒有人可以阻擋你設定高價

6.將 NFT 收藏放到 MetaMask 小狐狸上

在 OpenSea 中查看你的資產，例如我這個 NFT 的連結，https://opensea.io/assets/matic/0x2953399124f0cbb46d2cbacd8a89cf0599974963/4569312194679960174525000099739852468515614363778901331080870246133440446465/

找到 Details 資訊

將 Contract Address 以及 Token ID 複製出來

Contract Address : 0x2953399124f0cbb46d2cbacd8a89cf0599974963

Token ID : 4569312194679960174525000099739852468515614363778901331080870246133440446465

並且把這兩個資訊輸入回你的 MetaMask 小狐狸錢包中即可看到你自己得收藏品了，記得狐狸錢包中要把鏈改成 Polygon

下載圖片以及上傳圖片比較

NFT 這麼的盛行，但我們不是會畫畫的，也不是會唱歌的，拍影片也不夠帥氣，只好發揮 IT 的專才，利用軟體工具來大量且快速的製作符合元宇宙的作品，簡單用滑鼠不需要專業的畫圖工具，就可以利用拖拉快速的畫出各種光與波動與絲的組合，並且每一張的感覺是設計系的大作，先看看下面的影片，然後直接去他們的網站玩玩看就知道我再說甚麼，Realy Cool AR!!

最近使用 Tatum API 架設了NFT 市集，但問題來了，上鍊的費用又貴又慢，我只是想測試和學習一下 NFT 的商務應用，發現了只要把 NFT 上到 Harmony (ONE) 上，就可以免交易費用，而且速度超快，而且 Harmony 鏈是以太鏈分出來的，可以說是 ERC 20 的完成版，可以跟幣安交易所以及MetaMask高度整合，可以安心使用。
