If verbose is true, returns an Object with information about blockheader <hash>. Arguments: 1. blockhash (string, required) The block hash 2. verbose (boolean, optional, default=true) true for a json object, false for the hex-encoded data Result (for verbose = true): { (json object) "hash" : "hex", (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" : "hex", (string) The block version formatted in hexadecimal "merkleroot" : "hex", (string) The merkle root "time" : xxx, (numeric) The block time expressed in UNIX epoch time "mediantime" : xxx, (numeric) The median block time expressed in UNIX epoch time "nonce" : n, (numeric) The nonce "bits" : "hex", (string) The bits "difficulty" : n, (numeric) The difficulty "chainwork" : "hex", (string) Expected number of hashes required to produce the current chain "nTx" : n, (numeric) The number of transactions in the block "previousblockhash" : "hex", (string, optional) The hash of the previous block (if available) "nextblockhash" : "hex", (string, optional) The hash of the next block (if available) "asset_guid" : "str", (string, optional) the transaction output asset guid if asset output "asset_amount" : n, (numeric, optional) the transaction output asset amount in satoshis if asset output "chainlock" : true|false (boolean, optional) Is block chainlocked? } Result (for verbose=false): "hex" (string) A string that is serialized, hex-encoded data for block 'hash' Examples: > syscoin-cli getblockheader "00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09" > curl --user myusername --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getblockheader", "params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]}' -H 'content-type: text/plain;' http://127.0.0.1:8370/
