Bitcoin getblockheader用法及代碼示例

比特幣(Bitcoin) RPC Blockchain API中getblockheader的用法及代碼示例。

用法:

getblockheader "blockhash" ( verbose )

如果verbose為false，則返回一個已序列化的字符串，即塊頭‘hash’的hex-encoded數據。

如果verbose為true，則返回一個對象，該對象包含有關塊頭‘hash’的信息。

參數1 - blockhash

類型：字符串，必填

區塊哈希

參數2 - verbose

類型：布爾值，可選，默認= true

對於json對象為true，對於hex-encoded數據為false

返回結果(對於 verbose = true)

{
  "hash" : "hash",     (string) the block hash (same as provided)
  "confirmations" : n,   (numeric) The number of confirmations, or -1 if the block is not on the main chain
  "height" : n,          (numeric) The block height or index
  "version" : n,         (numeric) The block version
  "versionHex" : "00000000", (string) The block version formatted in hexadecimal
  "merkleroot" : "xxxx", (string) The merkle root
  "time" : ttt,          (numeric) The block time in seconds since epoch (Jan 1 1970 GMT)
  "mediantime" : ttt,    (numeric) The median block time in seconds since epoch (Jan 1 1970 GMT)
  "nonce" : n,           (numeric) The nonce
  "bits" : "1d00ffff", (string) The bits
  "difficulty" : x.xxx,  (numeric) The difficulty
  "chainwork" : "0000...1f3"     (string) Expected number of hashes required to produce the current chain (in hex)
  "nTx" : n,             (numeric) The number of transactions in the block.
  "previousblockhash" : "hash",  (string) The hash of the previous block
