#數字貨幣創世塊留言
這是廣為流傳的中本聰在數字貨幣創世塊的coinbase寫下“The Times 03/Jan/2009 Chancellor on brink of second bailout for banks” 這句話正是泰晤士報當天的頭版文章標題,如下：




coinbase的值為


"coinbase":"04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73"
解碼方法如下:


python shell下：


"04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73".decode('hex')'\x04\xff\xff\x00\x1d\x01\x04EThe Times 03/Jan/2009 Chancellor on brink of second bailout for banks'
或者在shell下


->strings -n 20 blk00000.datEThe Times 03/Jan/2009 Chancellor on brink of second bailout for banks

以上圖片隱藏在如下交易中：


解碼方法如下:


把ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 和9173744691ac25f3cd94f35d4fc0e0a2b9d1ab17b4fe562acc07660552f95518交易中所有vxout的scriptPubKey匯出:


bitcoind getrawtransaction ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 1
匯出出所有vxout的scriptPubKey:


 "OP_DUP OP_HASH160 3d79626567696e206c696e653d3132382073697a OP_EQUALVERIFY OP_CHECKSIG" "OP_DUP OP_HASH160 653d38373736206e616d653d626974636f696e2e OP_EQUALVERIFY OP_CHECKSIG", ......
刪除所有OP CODE,得到如下


'3d79626567696e206c696e653d3132382073697a','653d38373736206e616d653d626974636f696e2e','6a70670d0a2902293d4a2a3a747073702a2b2b2b','2a8a2a8a2a2a290b2a926fa293902a2a77772a54',......
轉換為hex


'3d79626567696e206c696e653d3132382073697a'.decode(hex)
把結果按yenc解碼:


if c == '=' and esc != 1:    esc = 1    continuen = ord(c)if esc:    c2 = chr((n-42-64+256)%256)    esc = 0else:    c2 = chr((n-42+256)%256)

解碼方法:


把交易中所有vxout的scriptPubKey匯出,這個scriptPubKey比較特殊: scriptPubKey: OP_IF OP_INVALIDOPCODE 4effffffff 1443 bytes of data OP_ENDIF
刪除OP CODE
轉為hex
結果如下：
