getmininginfo displays incorrect diff

bitmark-cli getmininginfo { "blocks" : 451365, "currentblocksize" : 1000, "currentblocktx" : 0, "reward_next" : 15.00000000, "reward_max" : 15.00000000, "hashrate_4max_reward" : 35000000000, "difficulty" : 31.24732609, "errors" : "", "genproclimit" : -1, "networkhashps" : 40838757117513.62500000, "pooledtx" : 0, "testnet" : false, "generate" : false, "algo" : 0, "algoname" : "SCRYPT", "hashespersec" : 0 }

Seems the difficulty in getmininginfo just randomly picks a diff to display rather than the diff that the wallet is set for, which is scrypt.

ok we see how to do this, but for now you can use the weights in GetAlgoWeight() in core.cpp to scale the difficulty.

[crackfoo]

great thanks. Is equihash an auxpow algo?

[piratelinux]

They are all merge minable. But for equihash transactions are in "vector format" and for cryptonight both transactions and block headers are in vector format so that I don't have to parse the structure, just search the vector for the hash I need. No mining pool exists for this yet, I just tested this with my cpuminer-multi fork (branch mm).

Resolved in dev branch for v0.9.7.1 release.

The difficulties displayed are weighted difficulties ( a weight factor is applied to harmonize the relative value of hashes amongst the 8 algorithms.)

Now also displaying 'sdifficulty' or "simple" difficulty (before application of weighting factor)

Weights applied, from core.cpp:

// Based on tests with general purpose CPUs,
//       ( Except for SHA256 which was designed for simplicity and suited for ASICs,
//       so given a factor of 16 decrease in weight. )
//   Weighing gives more value to hashes from some algos over others,
//      because, for example a Cryptonight hash is much more computationally expensive
//      than a SHA256d hash.
//   Weights should ultimately reflect the market value of hashes by different algorithms;
//      this will vary constantly (and more significantly long-term with hardware developement)
//   As of June, 2018 these values are closely reflective of market values seen on
//      nicehash.com and miningrigrentals.com
