getBlock: getBlock

In dv-trading/moneRo: An R API to the monero daemon and wallet

Description

Full block information can be retrieved by either block height or hash.

Usage

getBlock(height, hash, ip = getOption("monerod.ip", "127.0.0.1"),
  port = getOption("monerod.port", 18081))

Arguments

height	int; the block's height.
hash	chr; the block's hash.
ip	daemon ip address
port	daemon port

Details

Provide either the height parameter or hash parameter, but not both.

Value

• blob - string; Hexadecimal blob of block information.

• block_header - A structure containing block header information. See getlastblockheader.

  • block_size

  • depth

  • difficulty

  • hash

  • height

  • major_version

  • minero_version

  • nonce

  • num_txes

  • orphan_status

  • prev_hash

  • reward

  • timestamp

• json - json string; JSON formatted block details:

  • major_version - Same as in block header.

  • minor_version - Same as in block header.

  • timestamp - Same as in block header.

  • prev_id - Same as prev_hash in block header.

  • nonce - Same as in block header.

  • miner_tx - Miner transaction information

    • version - Transaction version number.

    • unlock_time - The block height when the coinbase transaction becomes spendable.

    • vin - List of transaction inputs:

      • gen - Miner txs are coinbase txs, or "gen". height - This block height, a.k.a. when the coinbase is generated.

    • vout - List of transaction outputs. Each output contains:

      • amount - The amount of the output, in atomic units.

      • target -

      • key -

    • extra - Usually called the "transaction ID" but can be used to include any random 32 byte/64 character hex string.

    • signatures - Contain signatures of tx signers. Coinbased txs do not have signatures.

  • tx_hashes - List of hashes of non-coinbase transactions in the block. If there are no other transactions, this will be an empty list.

• status - string; General RPC error code. "OK" means everything looks good.

Examples

# Look up by height:
# In the following example, block 912345 is looked up by its height.
# Note that block 912345 does not have any non-coinbase transactions.
# (See the next example for a block with extra transactions):
## Not run: 
getBlock(912345)

## End(Not run)

# Look up by hash:
# In the following example, block 993056 is looked up by its hash. Note that
# block 993056 has 3 non-coinbase transactions:
## Not run: 
 getBlock(hash="510ee3c4e14330a7b96e883c323a60ebd1b5556ac1262d0bc03c24a3b785516f")

## End(Not run)
