getnetworkhashps

getnetworkhashps ( nblocks height ) Returns the estimated network hashes per second based on the last n blocks. Pass in [blocks] to override # of blocks, -1 specifies since last difficulty change. Pass in [height] to estimate the network speed at the time when a certain block was found. Arguments: 1. nblocks (numeric, optional, default=120) The number of previous blocks to calculate estimate from, or -1 for blocks since last difficulty change. 2. height (numeric, optional, default=-1) To estimate at the time of the given height. Result: n (numeric) Hashes per second estimated Examples: > bitcoin-cli getnetworkhashps > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "getnetworkhashps", "params": []}' -H 'content-type: application/json' http://127.0.0.1:8332/
