Please test @mayankchhabra

[mayankchhabra]

nice, I think you missed the hashrate

[mayankchhabra]

I also suggest removing all the other unrequired info from the stats endpoint because it can increase the request's response time, especially when the polling happens on tor

[nolim1t]

nice, I think you missed the hashrate

hashrate is difficulty

[mayankchhabra]

we need the network hashes per second...

[nolim1t]

How is

{
  "blocks": 627734,
  "difficulty": 15958652328578.42,
  "size": 311151022856,
  "mempool": {
    "loaded": true,
    "size": 3889,
    "bytes": 1536424,
    "usage": 6171792,
    "maxmempool": 512000000,
    "mempoolminfee": 1e-05,
    "minrelaytxfee": 1e-05
  },
  "connections": 11
}

for mempool

[mayankchhabra]

sure but we still don't need a lot of it... just

{
    peers: <number of connected peers>
    mempool: <size of amempool in bytes>
    hashrate: <network hashes per second>
    blockchainSize: <the estimated size of the block and undo files on disk>
}

would be fine

[nolim1t]

Not sure what is what in mempool to be honest.

[nolim1t]

we need the network hashes per second...

That might be challenging to get.. its not the same command and the library this is using is also unmaintained

[nolim1t]

found the function

[nolim1t]

However the hashes per second is not being returned from the library

[nolim1t]

so it might be a new function, added after they stopped maintaining

[nolim1t]

  "blocks": 627735,
  "difficulty": 15958652328578.42,
  "size": 311152526222,

    "loaded": true,

    "minrelaytxfee": 1e-05
  },
  "connections": 10,
  "hashespersec": 109983984577136800000
}

However may require modifying upstream code which the last time it looks updated was June 2019

[nolim1t]

I can try to send a pull request (bitpay/bitcoind-rpc#54) but I doubt anyone is maintaining it

[mayankchhabra]

ah I see, does it have bitcoin-cli getmininginfo? network hash ps is also returned in the mining info

[nolim1t]

From mining info

Testing now

[mayankchhabra]

Tested and merged! Great job as always @nolim1t
