And how to refuse to transfer later?
Transactions tab, select tx, right click, choose "Abandon transaction". Afterwards, optionally: Debug Window -> Wallet Repair -> Recover transactions. Cheers Graham |

Coins are still not sent
It happens, it doesn't imply any error, just that the network is under-populated. Give it 24 hours, then if the tx hasn't gone through, abandon the tx and try again. I cannot replicate your problem, I sent 10 DTC to freiexchange, confirming with no problems. Cheers Graham |

Looks okay. Those are the (atm, only) two nodes that are configured to listen ( listen=1) and process/confirm txes. Cheers Graham |

writes an error in the console
addnode 213.31.19.87 add
Error: Node already added (code -23)
As long as you see 144.76.118.44 in the list of peers (enter getpeerinfo in the console or check the "Peers" tab), your client should be able to sync. Cheers Graham |

Interesting. OP has been editing their posts. Back on page 6: Can you also please elaborate on this: First of all, Gapcoin follows Riecoin's way and uses enough Miller-Rabin tests with random bases to avoid composite numbers being accepted as Prove of Work, like Primecoin mistakenly could.
Checking back though pp1-6, there's no such statement in any of j0nn9's posts to be quoted, so it must have been subsequently edited out. On different topic, Riecoin successfully upgraded to 0.20 back in March and is now on 0.21 with the benefit of having TapRoot and Schnorr signatures available via soft fork. Somewhat obviously, while the Gapcoin network remains predominantly hosted on 0.9 clients, there is no point in me pursuing any upgrade of Gapcoin to 0.20/0.21. Cheers Graham |

What table where can I see?
Sorry, I don't understand the question. What table do you want to see? Cheers Graham |

Because earlier the difficulty was more, the income was twice as much as you have on the pool now with low difficulty
It might seem like that but, in reaiity, it can't be true. Difficulty has dropped since March 3rd when the coinsforall.io pool went down but not enough to explain an apparent 50% drop in income. Date: 10/03/2021 00:55 - 3872381 - Difficulty: 8.9318 - coinbase: 12.64568656 DTC
Date: 10/04/2021 00:41 - 3919500 - Difficulty: 8.9595 - coinbase: 12.89000000 DTC
Date: 10/05/2021 00:19 - 3955926 - Difficulty: 8.8470 - coinbase: 12.95000000 DTC
Date: 03/06/2021 13:41 - 3985441 - Difficulty: 8.5357 - coinbase: 13.86000000 DTC
You've apparently been led astray by relying on faulty calculations: I have more than 10 blocks per minute
Common sense should have prompted you to question this figure. Datacoin, as a clone of Primecoin, has a target block spacing of one minute, enforced by Sunny King's scheme of continuous difficulty adjustment, so a figure of > 10 blocks per minute simply cannot be correct. Feeding bogus figures into a mining calculator merely propagates the absurdity: mining calculator
Your CPD:12500
Difficulty:8.4189
Include pool fee (4%)Calculate
DTC per day: 100510.967
Daily target block spacing is 60 * 24 which is 1440 blocks, not 12500. This has misled you into making incorrect assumptions which you unfortunately expressed publicly: Pool ( dtc.graymines.net) SCAM. 80 percent the pool takes for itself do not mess with this pool
You might gain a clearer insight into your mining income by entering the values into a spreadsheet. Cheers Graham |

It might help clarify things if you could post the JSON result from interrogating your Datacoin client for getinfo (or getblockchaininfo, depending on version). Cheers Graham |

In other news: Primecoin github repos has clones of eXtremal's solo and pool XPM miners, both CPU and GPU flavours which may well work with Datacoin and both of which have seen recent development activity: https://github.com/primecoin/xpmminerhttps://github.com/primecoin/xpmclientThe released cuda binary didn't work for me but ... eXtremal's post of 2021-03-07 provides URLs for his XPM nVidia GPU binaries: The Linux one worked out of the box for me, all I needed to do was change the URL to dtc.graymines.net and use my DTC addy (DNN2uuPUFrcwuKs29KwFHtR5ctRbio4H8Z) - with reasonable results. Cheers Graham |

Any chance of a bootstrap please?
Takes for every to download chain, and my other roaming directories don't work with this version without a full re-index
I presume you want a snapshot of the chain rather than a bootstrap.dat file? I'll have to make it available from my Mega.nz a/c - bootstrap.dat.xz is 1.2Gb, dtcchain-snapshot.zip is 2.6Gb, exceeds Github's limit: “We don't limit the total size of the binary files in the release or the bandwidth used to deliver them. However, each individual file must be smaller than 2 GB.” fwiw, it took about 4 hours to sync from 0. Cheers Graham |

That is only my guess, perhaps Graham or someone else has the retarget figures?
According to the comment - // NOTE: PRIMECOIN continuous target adjustment on every block. The implementation is deeply technical ...hopefully someone can find the whitepaper and that should have the diff retarget details in it.
Sunny King's Primecoin white paper - I don't have enough maths background to understand it. Co-incidentally, investigating this turned up the fact that the CalculateNextWorkRequired call in pow.cpp and pow.h is effectively unused: $ grep -rn CalculateNextWorkRequired datacoin-core/src/
datacoin-core/src/test/pow_tests.cpp:25: BOOST_CHECK_EQUAL(CalculateNextWorkRequired(&pindexLast, nLastRetargetTime, chainParams->GetConsensus()), 0x1d00ffff);
datacoin-core/src/test/pow_tests.cpp:37: BOOST_CHECK_EQUAL(CalculateNextWorkRequired(&pindexLast, nLastRetargetTime, chainParams->GetConsensus()), 0x1d00ffff);
datacoin-core/src/test/pow_tests.cpp:49: BOOST_CHECK_EQUAL(CalculateNextWorkRequired(&pindexLast, nLastRetargetTime, chainParams->GetConsensus()), 0x1c02b305);
datacoin-core/src/test/pow_tests.cpp:61: BOOST_CHECK_EQUAL(CalculateNextWorkRequired(&pindexLast, nLastRetargetTime, chainParams->GetConsensus()), 0x1d00e1fd);
datacoin-core/src/pow.h:22:unsigned int CalculateNextWorkRequired(const CBlockIndex* pindexLast, int64_t nFirstBlockTime, const Consensus::Params&);
datacoin-core/src/pow.cpp:54:unsigned int CalculateNextWorkRequired(const CBlockIndex* pindexLast, int64_t nFirstBlockTime, const Consensus::Params& params)

Is there a windows software that I can use for solo GPU mine? (i doubt GPU mining would work with WSL).
Yes ... and no. eXtremal-ik7 maintains a Github repos with open source code for a standalone XPM miner but there isn't a Windows version available and I've not yet managed to compile it successfully on a modern Linux distro. However, it does seem as though there might be a Windows compilation path, for example QtCreator can work with CMake on Windows. If I get time, I'll fire up a Windows VM and take a look at the feasibility. However, minerja's answer is correct in his response: *** Simply enter the console and type "setgenerate true x" where x is number of cores you want to mine with....works fine (use cores not threads though, well at least for AMD) *** ... in order to succeed it would need a lot more libraries for development (Node.JS, PHP, etc..), a lot more wallets. So that it's much easier to setup and run on servers. Projects would be born much faster if DTC had ways to quickly deploy on a web server, to create services, more trading platforms, etc...
I see that Primecoin has a primecoind release and that a lot of libraries use that. Can datacoin just run in command line and accepts an RPC connection? Or does it require a GUI? (just wondering if I can build a JS library and even an API for developers to use).
The Datacoin 0.16.3 client is pretty much a straight clone of Primecoin 0.16.3 (itself a fairly straight clone of Bitcoin 0.16.3), so yes, there's a datacoind and a datacoin-cli which can be run from the command line and which accepts all the RPC commands that Bitcoin can, as well as a few more (e.g. senddata). As an indirect but straight clone of Bitcoin, you'll find that most external libraries that can talk to Bitcoin can talk to Datacoin - the only thing they won't do is say anything about the data stored on the Datacoin chain because that's specific to Datacoin. However, there are libraries and support packages in the Datacoin Github repos which can show the data (e.g. j0nn9's DTCBrowser). HTH Cheers Graham |

Pool ( dtc.graymines.net) SCAM. 80 percent the pool takes for itself do not mess with this pool
*** Mined using graymines over last 4 years, can't really say i have noticed any issues *** Been mining on graymines for a few months now without any real issues. At one point, payments stopped but blocks were still being generated so I didn't see it as a major issue: DMd MarcusDE@here who responded within an hour with the action he'd already taken and a promise to give it his full attention at the weekend - which he did and the payment blockage was resolved. MarcusDE runs the pool to support the DTC chain: dtc.graymines.net pool is back to help DTC network ;-)
fwiw, eXtremal.ik71 used to run a DTC pool on coinsforall.io but when that fire occurred the data centre, the DTC pool went away and hasn't yet been restored: coinsforall.io was in destroyed SBG2 (with backups), now reopened.
Bummer. Good that you could re-open so soon. Looks like you took the opportunity to close the Datacoin pool? Cheers Graham Ok, DTC pull will be recovered little bit later. So, MarcusDE has my thanks for his continued support of the DTC chain. Cheers Graham |

Update to 0.16.3 client, “extended” versionSeth Troisi, of the Mersenne Forum's Prime Gap Search group, has slightly changed the way that the prime gap list is maintained and the URL for the latest list ( allgaps.sql) has changed, necessitating an update of the Gapcoin 0.16.3 extended client (the "minimal" version doesn't have the checkprimegaplist RPC API facility so is unaffected). If you're using a downloaded binary of the 0.16.3 extended client version and want to use the checkprimegaplist console/RPC-API call to monitor the as-yet-uncommitted Gapcoin records, you need to download a fresh binary from the Github releases. (If you're running a self-compiled version, just git pull and recompile.) Cheers Graham

Now I know why they don't have the Engineering guys running the Sales department.
Was a lost cause from the beginning. This person arrived with a negative judgemental attitude, was trying to mine with an unsynced wallet and exhibiting the typical demanding impatience of someone looking for free internet money and not finding it: I downloaded the wallet, but unable to mine with it.
...
Wallet not full synchronized yet.
...
I have be able to mine with the GPU and the pool.
...
But it very complicated, many broked/dead link,
Not updated.
...
This projet is still moving foward?
Team?
Roadmap?
Not exactly a great loss to the community. * gjhiggins waves Cheers Graham |
