Transactions
eth_getTransactionByHash 中的 v, r, s 是什麼意思？
在Ethereum JSON-RPC中，我發現返回是：
Returns Object - A transaction object, or null when no transaction was found: hash: DATA, 32 Bytes - hash of the transaction. nonce: QUANTITY - the number of transactions made by the sender prior to this one. blockHash: DATA, 32 Bytes - hash of the block where this transaction was in. null when its pending. blockNumber: QUANTITY - block number where this transaction was in. null when its pending. transactionIndex: QUANTITY - integer of the transactions index position in the block. null when its pending. from: DATA, 20 Bytes - address of the sender. to: DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction. value: QUANTITY - value transferred in Wei. gasPrice: QUANTITY - gas price provided by the sender in Wei. gas: QUANTITY - gas provided by the sender. input: DATA - the data send along with the transaction.但是我輸入命令，結果和上面的文件不一樣：

r,s和其他是什麼v意思？而且
value: QUANTITY - value transferred in Wei，這是什麼意思？
v,r,s是交易簽名的值。它們可以用作獲取任何乙太坊帳戶的公鑰更多資訊，
r是sECDSA 簽名的輸出，v是恢復 ID。 https://bitcoin.stackexchange.com/questions/38351/ecdsa-vrs-what-is-v也適用於乙太坊。為了防止重放攻擊，乙太坊對EIP 155v中的解釋做了進一步的調整。
value是多少 Wei 被發送到該to地址。1 ETH 是 10^18 wei。QUANTITY基本上意味著該值以十六進制編碼。
