RBPPS payout scheme

This scheme is getting popular, and it sounds better than PPLNS.

Wired VarDiff, only increase but don't decrease

Currently, I have this setting.

 "ports": {
            "3132": {
		"listenAddress": "0.0.0.0",
                "difficulty": 0.05,
                "varDiff": {
                    "minDiff": 0.01,
                    "maxDiff": null,
                    "targetTime": 30,
                    "retargetTime": 60,
                    "variancePercent": 30
                }
            }
}

But resulting in:

As you can see, the difficulty is increasing even the shares submitted time longer than my expect.

Could you add a GlobalToken (GLT)?

Dears,

Could you add a GlobalToken? it uses a same algorithm of Bitcoin but PoolMiningEngine does not have its information.

Support for Multi-Algos of DGB

At the moment, miningcore only support Scrypt for DGB. It would be better if mining core can support multi-algos coins like DGB.

how is the PPLNS?

Today morning, I successfully mined my first block.

Here is the block detail:

[

blockheight: 742811,

Here is the log for paying process.

I finally got 0.44637, and my friend got 0.00001. So where is others as the block reward is 1.79557754

Reset stats after reboot

You can make so that the stats remain after a reboot miningcore?

Quark ?

Is there no support for Quark coins ?

Continous Integration

MPOS compatibility mode support

It's better to support MPOS compatibility mode so that it can function as a drop-in-replacement for python-stratum-mining. And we can have a good front end for usage while this project have no website provided at this moment.

Use Wiki for not-that-important info in README

@oliverw can you create Wiki pages (can't do that on my end)? I think API, configuration in README can move into Wiki pages.
We should avoid a super long README.

Blocks API Endpoint should show all blocks found

I suggest blocks endpoint should show all blocks found including pending blocks with the confirmation count. I just mined two blocks half hour ago. the endpoint still show no blocks. But when I use the DashCore Windows Wallet. It can show two pending transactions are coming. Dash Explorer also can show the blocks.

VarDiff with low retargetTime throw System.NullReferenceException

Updating VarDiff if there is no shares submitted will throw Exception. I suggest we should consider updating diff at least one share even with low retargetTime and high start Diff.

Improving API responses

As I am working on the client-side UI, I think there are few improvements can be done on API for developer use.

/api/pools

1. Instead of providing "coin": { "type": 5 },, give the coin symbol instead. In this case, it is XMR. It is not friendly for integrations.
2. "payoutScheme": 1,, which is better to give PPLNS. same problem as above
3. networkHashRate, poolHashRate unit? H/s? kH/s? MH/s?
4. It is weird to put poolFeePercent, donationsPercent inside poolStats. I think they belongs to paymentProcessing or a brand new item.
5. lifetime pool shares received/ blocks founds?

The API should avoid hardcoding definitions into the UI, especially UI shouldn't need to update their coding once MiningCore added new coinType/ changed coinType numerical value.

/api/pool/{poolid}/stats/hourly

6. is it possible to provide the networkHashRate, connectedMiners as well?
7. same as 3.

/api/pool/{poolid}/blocks

8. what is status here? same problem as above

/api/pool/{poolid}/payments

9. same as 1.

Other issue:

10. there isn't an endpoint for miner list.
11. miner minute stats

I will continue update this issue while I am implementing the UI.

Web front-end progress/ code

I saw your comment on reddit saying that the web front-end is in the works. Can you tell us how's the progress? If there are some codes, can you push the incomplete code to GitHub in a different branch (so anyone can help)? If not, I can try to port other UI e.g. poolui?

Wrong transaction url for dash

https://github.com/coinfoundry/miningcore/blob/80f6ebe7590a7137a33f3ea04bf6e6f89e6ff500/src/MiningCore/Api/ApiServer.cs#L105
DASH is not the same as DSH.
DASH is Dash
DSH is Dashcoin

The current url is https://chainradar.com/dsh/transaction/[txnid]

The correct url should be
https://chainz.cryptoid.info/dash/tx.dws?[txnid].htm

Configuration file for two-three coins

Is there any example file of how to configure Miningcore for run several coins at one pool?
Also interested is there any posibility to connect Miningcore with MPOS or any other webui?

I have tried curl, it works:

curl \
	-u username:passowrd --digest \
    -X POST http://10.138.0.5:13301/json_rpc \
    -d '{"jsonrpc":"2.0","id":"0","method":"get_info"}' \
    -H 'Content-Type: application/json'

I guess it should be the authentication problem.

Banning mechisiam for unstable hashrate.

When using pool farm like nicehash, the hashrate is very unstable during bidding.
the current mechisiam is checking the last 51 shares validition ratio. if it over 51%, the miningcore will ban the client. when low diff, and fast start from nicehash, shares submitted is too quick. once rejects occurs, it mush be banned as it can submit 51 invalid shares in one second.
so i would suggest to change the banning mechisiam to checking invalid ratio in period of time instead of hecking last n shares. it would be better for ubstable hashrate clients.

Merged mining support for same algorithm like following?

Dears,

How can I setup a merged mining using MiningPoolEngine for following coins?

• Bitcoin and Namecoin and GlobalToken
• Dogecoin and Litecoin

Thanks in advance.

Coin support request: Siacoin (SC)

As there isn't many Siacoin pool out there, and no other pool softs support this coin, I would like to request support for Siacoin (so I can build one).

this will work in same sever

hi
i need to ask do this pool software is multipool software .. i mean if i add all coin is same server and will it work or not ..

for every coin i nee to use differ server or in same server i can install all and run it ??

also when gonna user ui will come

PROP Payout scheme

Implement PROP Payout scheme

TLS/SSL Support

Stratum over TLS eliminates possibility of man-in-the-middle attacks, as the communication between miner and pool is strongly encrypted and the server's identity is digitally signed by a certificate authority. Implementing this feature has top priority.

PPLNS incorrect payout?

I have an ETC config.

I am the only miner on this pool during testing with 300MH. A block was found by me. But my pending balance is:

"pendingShares": 56139,
"pendingBalance": 0.421189398082,
"totalPaid": 0.0,

This is on Linux using Claymore. So there is the small dev fee connection. Is it really causing that much of a loss?

[I] [btc1] [Bitcoin Job Manager] Waiting for daemons to come online ...

When I start dotnet "dotnet MiningCore.dll -c config.json, I get massage [I] [btc1] [Bitcoin Job Manager] Waiting for daemons to come online ....

But daemon is working. http://joxi.ru/GrqGg7ztNOYBk2.

build/config.json has RPC password.
And I have access by curl to RPC.

How can I solve this problem?

Thanks!!!

mine to exchnage support in monero

do this allowed option to mine directly to exchange ? do it has the option to add rig name and worker name in miner so separately see the stat for all the rig they have ??

ZCash support

The foundations for supporting ZCash are already implemented

• Equihash native Interop is fully functional and tested
• ZCashPool can most likely remain unchanged
• ZCashJob is needs to override several method from its base class to correctly support ZCash

Question regarding backup daemons.

I have a question regarding how the backup daemons work.

From what I can see, blocks are being submitted to all registered daemons but payments are being processed using only the first one in the list.

Won't this be a problem at some point, since blocks could be submitted to other daemons but payments will be processed only from the first daemon/wallet?

Cannot send out Dash to Dash Address

I am trying to send out the Dash to my private wallet.
An error occur:

But My valid address should be:

XrQsEqFfabd5mGy7W9vjBnvk6K19oc97gB

the first X is a capital letter.

I have checked my miner config and the miningcore miner stats. Both are correct.

Inconsistent timestamps.

First not sure why UTC is the default time instead of the systems time?

The logging to a file uses system time but the database uses UTC. As well as the API output. Can we get a standard? Preferably system time.
