標題Re: [DeFi] 智能合約與抽獎程式的適性
時間2024-11-17 10:42:12
坐而言不如起而行，用區塊鏈抽獎根本簡單到連智能合約都不用寫。 早起的鳥兒有獎抽，現在就來舉辦抽獎吧。 頭獎是0.0888 BCH，直接發送到參與抽獎的地址，當然無法作假。 但是有很多抽獎活動還有其他獎品的，不一定都是獎金。 那其實可以先用NFT的形式公開的發放，就幾乎不可能作假且高隱私性。 之後再憑NFT向主辦單位領獎。 所以二獎一名我發一個Punk APE做範例代替。 https://tinyurl.com/4zaxh38y 當然也不一定要NFT，也可以是FT，所以第三名三獎我發1000枚Pcash 抽獎辦法： 1. 留下你的bitcoincash地址，必須是cashaddress格式， 也就是通常是bitcoincash:後接q或是p的地址。 譬如 qp800f4p6jj79cnttr6y3qerlsvqyxul9v5z3carky 或是直接貼QRcode也可以。 2. 然後你會收到一筆交易。這只是作為抽獎憑證。 抽獎序號直接看你的交易hash，取後八碼 https://tinyurl.com/34mhh7he 譬如以上交易的hash抽獎序號就是 16c2c94b 3. 開獎日訂於台灣時間11/18禮拜一晚上十點後產生的第一個BCH區塊 取block hash的後八碼當作中獎號碼參考值。 譬如這個block 872596的hash就是 https://blockchair.com/bitcoin-cash/block/872596 15898eb3 然後去比較之前各個中獎序號的差值， 最接近的第一名是頭獎，第二名是二獎，第三名三獎。 二獎和三獎得獎者需提供cashtoken地址以收取NFT和FT。 ========== 抽獎現在開始，限前50名留下BCH地址的不重複板友。 須注意地址有沒有因為推文長度受限而截斷不完整。 -- ※ 發信站: 批踢踢實業坊(ptt.org.tw), 來自: 36.236.218.252 (臺灣) ※ 文章網址: https://ptt.org.tw/DigiCurrency/M.1731811334.A.5A6
