feat: add support for ravencoin #1627

jon4hz · 2023-02-14T22:08:32Z

Hi, this PR adds support for ravencoin and lays the basis for other kawpow coins.

The code was tested on the ravencoin testnet.

Even though ravencoin is a fork of bitcoin, it has a different stratum protocol. This is why I added it as a custom family which extends the BitcoinJob and BitcoinJobManagerBase classes.

Payouts are handled by the BitcoinPayoutHandler without any modifications.

Nice :)
I was planning to give Kawpow a try but it looks like, you beat me to it :)

MiningCryptoLive · 2023-02-22T18:46:51Z

I would like to try raven coin. Is this merged into miningcore or do I need to submit a request from jon4hz?

jon4hz · 2023-02-23T00:05:18Z

no, this isn't merged yet. Hence the PR..

MiningCryptoLive · 2023-02-23T00:12:27Z

Cool. Hopefully oliverw will merge the pr soon. If I clone your repo will it work? If I checkout the branch ravencoin?

Probably, yes

Konstantin35 · 2023-02-23T11:59:12Z

Tested this project conditionally working there are many inaccuracies such as diff target
correctgey will be

    public static BigInteger BigMaxValue = BigInteger.Pow(2, 256);
    public static readonly BigInteger Diff1 = BigInteger.Parse("00000000ffff0000000000000000000000000000000000000000000000000000", NumberStyles.HexNumber);
    public static double Mul = (double) BigInteger.Divide(BigMaxValue, Diff1);

var shareDiff = (double) BigInteger.Divide(RavencoinConstants.BigMaxValue, resultValueBig) / RavencoinConstants.Mul;

    public static string EncodeTarget(double difficulty)
    {

        BigInteger BaseTarget = BigInteger.Parse("00000000ffff0000000000000000000000000000000000000000000000000000", System.Globalization.NumberStyles.AllowHexSpecifier, null);

        difficulty = 1.0 / difficulty;

        BigInteger NewTarget;
        BigInteger DecimalDiff;
        BigInteger DecimalTarget;

        NewTarget = BigInteger.Multiply(BaseTarget, new BigInteger(difficulty));

        string StringDiff = difficulty.ToString(System.Globalization.CultureInfo.InvariantCulture);
        int DecimalOffset = StringDiff.IndexOf(".");
        if(DecimalOffset > -1)
        {
            int Precision = (StringDiff.Length - 1) - DecimalOffset;
            DecimalDiff = BigInteger.Parse(StringDiff.Substring(DecimalOffset + 1));
            DecimalTarget = BigInteger.Multiply(BaseTarget, DecimalDiff);

            string s = DecimalTarget.ToString();
            s = s.Substring(0, s.Length - Precision);

            DecimalTarget = BigInteger.Parse(s);
            NewTarget += DecimalTarget;
        }

        return string.Format("{0:x64}", NewTarget);
    }

and OnSubscribeAsync

        manager.PrepareWorker(connection);

        var data = new object[]
        {
           null,
           context.ExtraNonce1,
        }
        .ToArray();

    public void PrepareWorker(StratumConnection client)
    {
        var context = client.ContextAs<RavencoinWorkerContext>();
        context.ExtraNonce1 = extraNonceProvider.Next();
    }

I didn’t check the block on the test network, I didn’t catch the payout yet, but I’m going to do it and write it.

jon4hz · 2023-02-23T22:45:47Z

Hi @Konstantin35

Thanks a lot for taking a look at this!

Good hint with the target encoding. I was actually quite unsure if I handled that correctly but I kinda forgot about it since the code seemed to work. (It actually does work but I think I'm loosing some precision down the line.)

I ported the share validation from blinkhash's foundation pool and I never heard that they do it wrong.
https://github.com/blinkhash/foundation-v2-ravencoin/blob/4ed8f799ff6594926c48509c8f3292886d660932/stratum/main/manager.js#L167

What makes you think that Diff1 should be "00000000ffff0000000000000000000000000000000000000000000000000000"?

As for the subscribe params: wildrig accepts both variants. Is there a particular reason to only send null + extraNonce1?

jon4hz · 2023-02-24T15:06:46Z

No it does not.
d3dcec6

furcalor · 2023-02-24T15:43:55Z

No it does not. d3dcec6

Stand corrected, not sure if its because of old base for me, but I also needed to add:

   {
        KawpowHasher = new EthashLight();
    }
    #region Overrides of CoinTemplate

    public override string GetAlgorithmName()
    {
        return "KAWPOW";
    }

    #endregion

to clusterconfigextension so it would not use the headerhasher as displayed algo.

jon4hz · 2023-02-24T15:54:16Z

Good catch! Fixed in 1f3df14

When testing the same problem as Ethash: Abstract and light cache jumping pings on Ethash tested with dag generation there is a stable ping difference with my pool of 1ms it turns out that with dag is much better. If you use light cache then you also need to generate cache files and test them.

jon4hz · 2023-02-25T16:12:44Z

When testing the same problem as Ethash: Abstract and light cache jumping pings on Ethash tested with dag generation there is a stable ping difference with my pool of 1ms it turns out that with dag is much better.

I'm no expert on ethash by all means but I think the performance difference can be explained, because the light cache has to calculate the required dag sequences on the fly, where as the dag has them already precalculated.

See: https://ethereum.org/en/developers/docs/consensus-mechanisms/pow/mining-algorithms/ethash/

Mining involves grabbing random slices of the dataset and hashing them together. Verification can be done with low memory by using the cache to regenerate the specific pieces of the dataset that you need, so you only need to store the cache.

How big was the performance difference in your experience? If it's only a ms I dare to say the advantage of being able to scale overwhelms the disadvantages. But yeah, that all depends on how big the difference is.

If you use light cache then you also need to generate cache files and test them.

I though that was already handled by the c++ code but I'll take another look. Doesn't it store the light cache in-memory?

Hello. I try kawpow algo on hivecoin. Have error with block submission: submission failed with: bad-cb-community-autonomous-amount
To coins.json i add "payFoundersReward": true,
Maybe we need to add something else. Or is the support for kawpow not finished yet?
Thanks.

You need to add support for "CommunityAutonomousAddress" and "CommunityAutonomousValue" as those are different to founder/payee/masternode/minerfund. Check the minerfund commit and follow that. Pretty easy to add.

I did lazy way and just added to getblocktemplate. Was going to do it properly with its own file and submit a pull request to jon4hz, but got distracted
In bitcoinjob:

        if (coin.HasCommunityAddress)
            rewardToPool = CreateCommunityAddressOutputs(tx, rewardToPool);

    #region CommunityAddress

    protected virtual Money CreateCommunityAddressOutputs(Transaction tx, Money reward)
    {
        if(BlockTemplate.CommunityAutonomousAddress != null && BlockTemplate.CommunityAutonomousValue > 0)
        {
        var payeeReward = BlockTemplate.CommunityAutonomousValue;
        reward -= payeeReward;
        var payeeAddress = BitcoinUtils.AddressToDestination(BlockTemplate.CommunityAutonomousAddress, network);
        tx.Outputs.Add(payeeReward, payeeAddress);
        }
        return reward;
    }
    #endregion // CommunityAddress

in getblocktemplate

        [JsonProperty(DefaultValueHandling = DefaultValueHandling.Ignore)]
        public string CommunityAutonomousAddress { get; set; }
        [JsonProperty(DefaultValueHandling = DefaultValueHandling.Ignore)]
        public long CommunityAutonomousValue { get; set; }

in clusterconfig

    [JsonProperty(DefaultValueHandling = DefaultValueHandling.Ignore)]
    public bool HasCommunityAddress { get; set; }

I think didn't miss anything, but might have.

Find new issue. Payments work, but there are no records in the database about payments made. No records in "payments" in db.

jon4hz · 2023-02-28T18:04:46Z

Are you using the same wallet for the pool fee and mining?

papagruz · 2023-02-28T18:07:21Z

Are you using the same wallet for the pool fee and mining?

Yes 1 wallet for fee and mining. Now try change wallet

jon4hz · 2023-02-28T18:08:47Z

Miningcore doesn't store payments sent to the fee wallet. You'll have to use a different wallet for mining if you want to test payouts.

Have new problem :)
On Paprikacon wrong block reward. On cryptonote pool right reward 36 coin.
On miningcore reward 12 coins.
Think miningcore set wrong CommunityReward.
In code set % reward? or miningcore take info from network?

Getting OT on kawpow, but paprikacoin has incorrect coinbasevalue on getblocktemplate, I submitted a pull request to fix it. In the meanwhile, check the pull request in paprikacoin git, apply it and build from source.

Sorry i'm a little bit late to the party.

I tried to mine RVN testnet using that PR, and both T-Rex Miner and SRBMiner-Multi are sending this method to the pool:

Am i the only one having that issue?

jon4hz · 2023-06-06T13:12:05Z

@blackmennewstyle that isn't an issue, just the miner reporting its hashrate to the pool. Miningcore doesn't support that though, so the message gets ignored.

Hi, sorry for the confusion i wanted to write behavior not issue, another brain glitch i guess. Everything is working fine, i had to decrease my minDiff though because my GPU for testing isn't really great at KAWPOW lol

Nice job mate 👍

Did you implement @Konstantin35 suggestions with the target encoding and also the shareDiff calculation?

I know lol But i think there is an issue with target encoding and shareDiff calculation because i'm getting from time to time, few low difficulty rejected shares and i think the modifications suggested by @Konstantin35 would fix them. So i imagine you didn't implement them into your pool then since you did not answer lol

blackmennewstyle · 2023-06-27T02:33:19Z

I implemented what is suggested here #1627 (comment)

After restart, all my low difficulty rejected shares are gone. That GPUs rig was mining on flypool before and it never got the amount of rejected shares i was seeing, maximum one per 24h.

I use Ravencoin diff 00000000ff000000000000000000000000000000000000000000000000000000 instead of 00000000ffff0000000000000000000000000000000000000000000000000000, the later is FIRO diff if i am not mistaken.
