今天來看一下HyperBlock裡面是放什麼資訊，
呼叫的url是

{{rpc-server}}/hyperblock/by-nonce/:nonce?withTxs=true

withTxs=true的話就會顯示transactions，:nonce帶的是block hight，我們看一下explorer跟api回傳的資訊。
API response

簡單介紹一些欄位定義

• data.hyperblock.hash: hyperblock hash
• data.hyperblock.nonce: hyperblock hight(metachain hight)
• data.hyperblock.numTxs: 有幾筆交易
• data.hyperblock.timestamp: block timestamp
• data.hyperblock.shardBlocks: shard block hight and hash
• data.hyperblock.transactions: all transaction in all shard

目前我們都只先看Elrond native token EGLD的交易，他的智能合約代幣ESDT token交易內容與EGLD交易內容不一樣，為了避免混淆目前先只講EGLD的交易，之後有時間再來談ESDT類型的交易。
對交易所來說鏈上行為只管轉帳，轉帳代表的是withdraw或是deposit，所以我們只會取幾個值來檢查

1. 檢查hash是否存在DB中，這邊之前有說到交易所會把parse過的block資料儲存在DB中避免重複處理
2. 如果不存在則檢查receiver or sender的address是否是交易所的address
3. 如果是的話檢查operation是否為transfer
4. 如果是的話檢查status是否為success
5. 如果是的話取得value的值，這個就是轉帳的金額然後再將hash儲存於DB中

ps.你會看到value是30000000000000000000這是因為decimal，用來精確表示數量，因為加密貨幣可以切割成很小位數去做交易，例如0.000000001 ETH，因為每個token設定的decimal不同，所以要特別注意這點!
EGLD和ETH的decimal一樣是10的-18次方，所以需要將30000000000000000000去乘10的-18次方也就是這次轉帳的金額是30顆EGLD。
接觸過不同的區塊鏈後，看他們的block的資訊和提交交易所要帶的資料等等的，可以更加的瞭解不同區塊鏈的設計風格，之後如果還心有餘力，會想要去看每個鏈怎麼處理共識這塊。
