1121  Alternate cryptocurrencies / Altcoin Discussion / Re: Successfully cloned and compiled POW/POS coin but how to pre-mine a coin? on: February 27, 2019, 07:26:15 PM
Thanks for sharing the screenshot. I am away from my PC now, so probably by tomorrow we may figure out a way to check these so that the coins are sent through to the wallet.

When the coins are generated, do I have to tell it to send it to the wallet address?
Yes you should. Coinbase transactions are included in the block and they are the ones that pays off the miners during the new generation of coins. ATM I am not able to find the code for coinbase tx, but they are the ones that use the scriptPubKey to identify the miner address. I guess you should be wrong somewhere while compiling or editing the code. Meanwhile you need to have a good understanding of how bitcoin and blockchain works, and for that try giving a read of Mastering Bitcoin Book which is present in the git for free.
1122  Alternate cryptocurrencies / Altcoin Discussion / Re: Confirmations in the source code on: February 27, 2019, 06:25:13 PM
Your question is pretty vague to be answered and doesn't seem to make sense actually. For the qt wallet to show the balances, you need to configure minconf option in the configuration file since those are the options which makes the wallet to show the balances. If you set the minconf=1 then the wallet will show the transaction which has got 1 confirmation from the network in the balances. If you set it to 0, you will see transactions with 0 confirmations. Unconfirmed transactions cannot be spent by qt wallet. If your transaction is a coinbase tx, then you need 100 confirmations from the network and here is the relevant code for that present in consensus.h

Code:
/** Coinbase transaction outputs can only be spent after this number of new blocks (network rule) */
static const int COINBASE_MATURITY = 100;

I have read somewhere an attacker can build a raw transaction for unconfirmed transactions, but if you do so and other nodes find that out, your node's IP address will get banned from using the network (in simple terms it would be blacklisted). I assume This code is present in the validations.cpp and can be seen here.

Code:
for (CTxMemPool::txiter ancestorIt : setAncestors)
        {
            const uint256 &hashAncestor = ancestorIt->GetTx().GetHash();
            if (setConflicts.count(hashAncestor))
            {
                return state.DoS(10, false,

                     strprintf("%s spends conflicting transaction %s",
                                           hash.ToString(),
                                           hashAncestor.ToString()));
            }
        }

Here the double spend transaction will be included in setConflict and the node which relayed them will be banned.

In my case, I have the transaction stuck in my altcoin wallet, but the transactions never get confirmed, they are staying in pending stage.

If you didn't specify enough higher fees, the transaction should be staying in the mempool which would be picked up by miner later to add to the block.

Also, move this thread to altcoin section to get better answer here https://bitcointalk.org/index.php?board=67.0
Pretty much bad idea. Do you think this would be answered in the Altcoin board? The spammers present there doesn't even know what a confirmation is! A single question present there about pre-mining is solely being answered by me for past 2 days and there isn't even one guy jumped in to learn what the OP is saying. Also I believe the question is based on a bitcoin fork, so asking questions here is probably right in my opinion.

Probably this guy has a really good posting quality and is just short of 3 2 merits to become a Full Member. His recent well written topics are being merited a lot, hence I skimmed through some older topics created by him and got one such topic which didn't receive any merits. Though this topic is pretty old (>7 months), he didn't receive any merits for these. Hence pointing this to Merit Sources so that he would rank up.

Possible bot activity to flood the Discussion board. There were around 30 brand new accounts recently nuked as reflected in the modlog around 2-3 accounts are still floating in the board for a filthy low life, hence reported them too and they would be nuked soon. The board is pretty back to normal state. This is the reason why theymos has appointed global mods from almost all the time zones to moderate the forum 24*7 restlessly. Both hilarious and mprep were last active yesterday, this should have been probably handled by rickbig41.
1125  Alternate cryptocurrencies / Altcoin Discussion / Re: Successfully cloned and compiled POW/POS coin but how to pre-mine a coin? on: February 26, 2019, 06:45:56 PM
I did went to check the Peercoin source and what you have explained above on Line #967 shows a totally different function.  Should I change the code to match what you have above?  I have also found another example coin using the same source code; however, the GetProofOfWorkReword function shows less compared to Compound Coin.  It is called 404coin. 
I need to know that is your alt coin capped or uncapped! Since Bitcoin is capped and the code which I have mentioned is based on that. If the coin is capped you need to clone the bitcoin code else if your coin is uncapped use the peercoin code. The function between what I have mentioned and what you have seen in the code is completely different because peercoin has an uncapped supply and it will emit the coins as long as the blocks are solved by the miners. Since bitcoin is capped, the halving takes place resulting in the decreasing of coins per 21000 blocks. I am unaware of how peercoin works, but I am giving out these suggestions to you completely based on bitcoin. I am aware of only bitcoin code and a little bit of ethereum along with smart contracts.

Also you need to note that I have far minimum knowledge on PoS coins and their coding mechanism. If you consider the peercoin code which has an uncapped supply and works on Proof of Stake mechanism, this code emits the coins when miner solves the block...

Code:
int64 GetProofOfStakeReward(int64 nCoinAge)
{
    static int64 nRewardCoinYear = CENT;  // creation amount per coin-year
    int64 nSubsidy = nCoinAge * 33 / (365 * 33 + 8) * nRewardCoinYear;
    if (fDebug && GetBoolArg("-printcreation"))
        printf("GetProofOfStakeReward(): create=%s nCoinAge=%" PRI64d"\n", FormatMoney(nSubsidy).c_str(), nCoinAge);
    return nSubsidy;
}

But to actually mine the coins, am I correct in the methods that I asked (i.e. using 2 daemons or running 2 wallet gui where one is the server and the other the client) or do I need to use a miner?  There should be an internal miner to test in seeing how to generate the coins.
You don't need to use a separate miner since you are finding the blocks at a lower difficulty. Once the difficulty rises, you need to shift yourself to higher processing units.

P.S You could have cloned bitcoin instead and could have directed your questions to the development and tech board of this forum. It is being visited by many devs and you could create your alt more easily. Altcoin Discussion board is shit and is clogged up with spammers who have no knowledge on anything and I might be the only one to help you in this situation  Undecided
1126  Other / Meta / Re: (Suggestion) sMerits Of Banned Accounts on: February 25, 2019, 03:50:03 PM
What if the guy who reports the post is a shitposter and a spammer? He would be meriting his alts or probably would be meriting the people he likes if he has received the decayed sMerits. This destroys the fair distribution of the merits and would rank up other spammers too. Possibly there are very few accounts apart from Newbies and Jr Members who are banned for plagiarism. Hence there aren't much sMerits getting wasted. Truly speaking a plagiarist will get caught and would be permabanned even before they reach the Member Rank with 10 earned merits. redsn0w and Hhampuz case was quite different, and they would be back within a month and a week.

But what about the sMerits that the nuked accounts are holding? They are going to be wasted? Right?
What about the sMerits satoshi, Hal, GameKyuubi and other inactive accounts are holding? satoshi has at least 848 sMerits clogged up in his account, GameKyuubi has at least 260 sMerits if we consider their received merits. People are still meriting them even though they know that these merits are getting decayed! If you are a good poster, merit sources will surely help you to receive the merits as they are being active in fair distribution.

We don't need these transfers anyway!
1127  Alternate cryptocurrencies / Altcoin Discussion / Re: Successfully cloned and compiled POW/POS coin but how to pre-mine a coin? on: February 25, 2019, 07:14:20 AM
Below is my project files:
https://github.com/skourdes/Compound-Coin

For the premine to be done, would that be in the checkpoints.cpp file?
Thanks for pointing me to your code so that it could be easier to explain the concepts. As far as I have seen, the so called compound coin seems to be based on the satoshi client a little. Here in the code, the subsidy values are mentioned starting from Line#967. Also your code seems to be pretty broken up,

For example if you consider the above bitcoin code which I have posted, it has been clearly mentioned the coins are cut into 2 after the halving takes place. Whereas in your code, there would be 94958891.757693062 coins generated if the block height is less than 25 and 1 coin would be generated if the block height is less than 1000 and 100 coins would be generated if the height is less than 50000.  Huh
I am totally confused with your code man.

After reading through PeerCoin a little, they don't seem to have a capped supply to prevent inflation and also they follow both the POW and POS algorithm. I have very little knowledge of POS code hence I won't be able to guide you through that.

P.S Checkpoints are used to prevent the hashing of block in lower difficulty. Since you are premining them in first or second block there is no need to change the code in checkpoints. They are probably used for future prevention of 51% attack in the network. Check out my explanation for checkpoints here :  What is use of Checkpoints in a cryptocurrency?

Is that you who have posted this same topic in bitcoin stackexchange? If so, that is wrong area to post that and you probably won't be answered since that doesn't belong to bitcoin and you are cloning an altcoin.
1128  Alternate cryptocurrencies / Altcoin Discussion / Re: Successfully cloned and compiled POW/POS coin but how to pre-mine a coin? on: February 24, 2019, 06:48:24 PM
It is only how the coins are generated where I am still trying to understand.
This is not a secret project to talk through PM, if we have successfully cloned the coin and premined them, this topic might serve someone who is looking through the same in future. I don't have much idea on how Peercoin works, but I have read that they do share the same code as bitcoin with minor changes.

I have cloned bitcoin once, and with the older version of bitcoin-qt client the coin generation probably takes place in the main.cpp code of the bitcoin. But with the newer versions coming into picture, this main.cpp of the older client has been split into net_processing.cpp and validation.cpp. If your compound coin code has main.cpp check for the GetBlockSubsidy method in it. Otherwise they would be present in validation.cpp of the code. The code would look like

Code:
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return 0;

    CAmount nSubsidy = 50 * COIN;
    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
    nSubsidy >>= halvings;
    return nSubsidy;
}

We need to consider that there are totally 100,000,000 satoshis in one bitcoin. Hence at the start of the code, 50 is multiplied with this 100,000,000 satoshis which yields 50 bitcoins in total as the initial Subsidy. Once 210,000 blocks are mined the subsidy is cut in half since nHeight is the total block height. When the 64 halvings are reached in total the code returns only 0. So after 64 halving period the miner receives only fees.
1129  Bitcoin / Bitcoin Technical Support / Re: My computer crashed. Back up wallet.dat shows balance of $0 on: February 24, 2019, 10:39:50 AM
Either you should have copied the wrong wallet.dat file as others said or you should have done something wrong while importing the file to sync with the newer version of the core wallet. If you have messed up with the wrong wallet.dat then you have lost your btc probably. If you are aware of the addresses which holds your money, try checking out in a block explorer so that you should make sure you haven't lost them forever.

If you have the same wallet.dat from the corrupted computer that still holds $2000, then after installing a newer version of OS and qt client try this to retrieve your coins

1. Download a newer version of core
2. Run the wallet software
3. Once it starts running, close it
4. The client should have created AppData folder in your Roaming folder
5. Replace only wallet.dat file with your older file

Since the wallet.dat is not a human readable file, you should export your private keys if you are willing to create a paper wallet

6. Restart the core, go to the console and type

Code:
dumpwallet [filename]

This will export the keys associated with the wallet.

7. Allow them to sync if you are gonna use core

Note that, you should close the client and replace the wallet.dat file with the older file. That's how it should be done as far as I have read.

There might be a chance that your wallet.dat could have crashed along with your computer. If so, try having a copy of the wallet.dat and replace them and run the -salvagewallet command. This command will help you in recovering the private keys associated with the wallet. Running this command is quite risky since there are chances that this will corrupt your wallet.dat file even more. Hence try this command when you don't have any other choice of recovering them. Also save a copy of .dat file prior trying this out.

Professional gamblers find out a way to recover the losses quite sooner than expected. But they all depend upon the gambling strategies they are going to incur in the further games. Winning at firsts will tempt us to earn more by gambling with more money but probably will lose them. If you have made a chunk out of gambling for months, you need to retire with that money. If we are greedy enough to earn more there are fair chances of losing more. Recurring the losses is also tough if you have a bad luck and trying the odds will complicate the situation even more and make you lose your remaining money.

Getting ourselves involved in online Gambling is quite dangerous at some times, but they seem to be more fair enough in recent times due to the developments in blockchain and smart contract technology. If you have been part of Online casinos and pokers you should have encountered few fraudulent websites which claims to offer surreal gambling experience, but they have been limited with the use of smart contracts.
1132  Other / Meta / Re: Can we expect some active mod in India forum? on: February 21, 2019, 02:06:13 PM
The Indian board has always been a hotbed for spammers, shitposters and more importantly scammers to promote their shitty scammy exchanges and offers. Benson was active in managing the spams only during 2017 and the board became bad right back in the start of 2018. After the coinsecure hack I guess he won't just get back to the forum to moderate the board or has become quite busy lately.

May I know why the above said topic of mine was removed?
Topics similar to these generate insane amount of spam by newbies and signature spammers to fill their post count criteria. Moreover such kind of topics doesn't help anyone and is more or less a spam generation topic which must be locked after certain replies or must be trashed. Also framing this as a legimate topic is not exactly right. On top of that topics like these, bring referral spammers to share their link. These newbie referral spammers probably necro bump very old topics to share their links to earn a few pennies.

I don't really post anything on the Indian board but I am a regular visitor to merit few good posts (which I rarely find) and trash the shit present out there. From what I have identified after 9 months of reporting hundreds of posts is that

1. The board lacks few sub boards such as Altcoin Announcements, Scam Accusations and Reputation Board. These are literally important since Altcoin Announcements are being spammed in the Regional Languages Board and Altcoins(India) Board.
The regional board should be used for discussing about Btc in Regional Languages.

2. The Altcoins (India) board is full of translation spams and most of them are being completely translated by Google Translator. Apart from very few trusted translators like erikalui who do their work sincerely, almost all the other translators are using Google Translator and lack the basic language skills to translate announcements. I can bring out those guys to limelight, but I am not a native Hindi guy and my assumptions might be wrong. If they are to be caught, those translations are to be removed and they should be painted red from DT.

3. A moderator is just a volunteer and not a defacto leader of the community. Most of the Indians believe that the Mods are leaders to govern them. A MOD is only for rearranging posts in right board, prevent spams at a larger extent and nuke newbies if they believe they are plagiarising or promoting scams.

4. Indian board is populated by newbie spammers (spambies with activities not higher than 1) and there isn't literally any real discussion taking place. There are few handful of good posters (TheUltraElite, avikz, amishmanish, legendster, newIndia, deadly,botany, Joel_Jantsen) who rarely visit the board (probably being more inactive) to share their thoughts and involve in discussion.

5. Most of them lack the knowledge to indulge in discussion and talk bullshit without reading previous replies. One liner spams, duplicate posting has been common in most of the topics in Indian board.

6. Most of the topics created in the board are for promoting new scam exchanges, a futuristic spam topic which would be populated soon enough by spambies.
This forum is for discussing and expressing thoughts and not for discussing shits to spam the forum.

It is clear that an elected mod can only clear the ongoing spams but can never bring back the board as it was used to be Benson period. Clearly stating that, the board lacks good posters/ the posters have moved on to main board and doesn't want to get themselves squinted with the ongoing spams.

And we need to take into account that India is a nation where centralization plays a major role. The elected moderator must not suppress the other members through his power. He must act as a fellow member along with others and needs to bring back old good posters who were active in the Indian board during Benson era.

IMHO The board is currently controllable with reports (assuming they are getting handled quite quickly). If the situation gets out of hands i.e reports are not regularly handled then we should pressurize theymos for appointing someone.

P.S could anyone spot an instance of at least one referral code spam in the Indian Board right now? It won't be, because I along with other reporters report them quite often and they are getting handled at a faster rate. The only child board which isn't moderated/reported right now is Altcoins (India) child board. There are huge google translation spams taking place, but since I am not a native Hindi guy (but can speak,read and write Hindi to quite an extent) I may still be bad at my decisions. I am open to PM from reputed native Hindi speaking Indians if they are willing to work with me to bring out those translation spammers.

P.P.S I have been viewing this topic since the time it was posted, and was reading through all the replies. I guess this should be the right time to appoint a MOD since the translators are getting out of control.

@theymos could you give us the statistics of who reports quite often in the Indian Board?

You are actually missing the topic.We are talking about Virtual Shoes not Coins.
No, I am on topic. If you have read the complete post of mine, you should have known what I was talking about.

 I was comparing these virtual skins with the virtual money. People buy since they like these and willing to pay what the seller quotes. It is completely based on trust and interest of a person when dealing anything about virtual products. These skins are pretty good when used in the games and gamers could be more addicted towards these products. I have seen that there also occurs real trading with these virtual products. It is about the demand and supply of these goods and the trust they have received from the market. Either way, these kinds of skins for making the game colourful and powerful(if you are buying a pistol) are adapted more commonly by the riches and poors are still finding a way to get past these activities.

50-300 is fine.
If we do not state a definite upper limit then we run into a Sorites paradox, where n+1 is as good as n and hence we arbitrarily increase.
Wouldn't it make those 50-300 limited run coins more costly? If they are rare, these coins will surely be auctioned in future which shouldn't happen, since theymos has said that he offers these anniversary coins to only to few specific members based on certain criteria. Also, it would be good if those members were selected who has really contributed to the forum such as MODS, devs of epochtalk (probably just an idea), donators and other reputed guys roaming here. This shouldn't be handed over based on so called merit criteria since not all top merit receivers know about collectibles and their uniqueness actually.

I like the sound of this. We could have a design and print done rather quickly, and be ready to ship before the anniversary.

If you are creating your own Altcoin then it would be easy to do a few minor changes in the code to premine the coins. You can fix the difficulty to lower limit and set the initial block reward to the premine number along with your coinbase transaction. Blocks which are mined later on will generate specified coins. By this way once you have mined the genesis block, it generates huge amount of coins as specified by you in the code and sends them to the address specified by you in the code.

If you have cloned the bitcoin core then you need to change the code further to spend your genesis block reward. There was a bug in the satoshi code which doesn't allow you to spend the reward which significantly affects your altcoin reward too. If you cloning a older bitcoin code, you can change the mining difficulty in mining.cpp or in the pow.cpp. I am not completely sure of this, but they will change the difficulty and help you premine those coins.

Possibly newbies should be disabled from receiving messages from users less than a Member rank. This should probably help them a little since the trust is too displayed in the PMs which might warn them about the user. If the scammer posts his mail ID in the topic, then the problem shouldn't be under the control of forum anymore. I do accept this forum acts as an entity or middleman for newbies getting scammed more often, but it lies with the user to verify before what actions they perform. Since I visit Tech Board quite often, when I try to help out a newbie and if the problem doesn't get solved, they message me for assistance. Isn't messaging me is quite irrelevant and if I was a scammer I could have scammed them easily in a go.  Newbies can easily fall for the scams provided if they initiate the discussion and doesn't know what is going on around them.

This is a decentralized forum, depending on quite few trusted individuals for a technical help isn't good. Anyone can help, provided the poster should be aware of his doings.
1137  Economy / Gambling discussion / Re: Disadvantages of Gambling on: February 20, 2019, 07:30:21 PM
Gambling is a dangerous addiction and one getting in the gambling industry faces a tough time in managing his gambling life and the financial life. People in States seems to be more commonly addicted to this gambling life and lose a hefty sum of money each year due to the poor strategies used by them in Gambling.

Some lose higher than expected and incur debts which would affect their personal life and more commonly their mental health. Gamblers are subjected to increased alcoholic addiction if they lose more than what they have gambled. Also they are subjected to intense pressure which might lead to unemployment.

Gamblers face a tough situation in their family too. If they lose money, they are subjected to pressure which gets transferred to others in god family. Gamblers due to their increased addiction will borrow loans and debts from friends and banks and would eventually lose them leading them to further problems in the society. Unless you are lucky enough to get back what you gambled you would more probably lose all the money.

Online Gambling has further disadvantages when compared to RL gambling. You would be confined within the virtual world and would have no contact with real players apart from the inbuilt chat. Casino downtimes are regularly being a frustration among online gamblers which would be difficult during peak seasons. On top of that, we need to trust the online websites for the withdrawal of our funds. Nowadays online gambling is receiving harsh criticisms due to the ongoing scams taking place all over the market.

Why would you spend money to buy "VIRTUAL SHOES" ?!?!
Would you actually spend $400 on buying shoes that you won't even get? This is a non-existing product ... it's virtual ... how come people spend $400 on products like this?
Why would you spend money to buy "Virtual Coins"?
Why are we spending more than $3750 for buying a virtual coin which you won't even receive them physically? How come everyone one of us spend money on buying "Virtual Money"?

It is the trust driving everyone to buy such things or probably we are shifting more towards the digital age rather than being physical. I don't use OpSkins much, but I do check the trades happening there quite often. We, the digital traders buy OpPoints for fiat money (I have seen somewhere that 100 OpPoints = $1, so if you have invested $100 you would be receiving around 10000 OpPoints and for those points you would be exchanging the skins. These skins can be used in games like Counter Strike and other prominent games using paid skins. They can also work as a tradable asset where you can sell them for higher profits or OpPoints. People even buy few skins from the Steam Market and sell them through OpSkins for Gamers and would make a good profit.

OpSkins has gained popularity in the digital world and gamers and traders are opting for OpSkins rather than depending on the Steam Market because they accept a wide variety of payments ranging from PayPal to Btc but Steam Market is based only on Steam Cash. OpSkins has been proven trustworthy on the market and Gamers are depending a lot on those.

If you are going for Hardware Wallets then you can try out Ledger as they support Bip 32,39 and 44 versions for the generation of seeds. Electrum doesn't generate Bip39 wallets but allows you to import Bip39 wallets generated from Ledger. After entering the seed words, click on "Options" button and select "Bip39 seed" and you would successfully import the Bip39 wallet keeping the derivation path as default specified by Electrum.

Apart from these, Bread Wallet uses Bip39 support if you have an IOS based mobile and I also assume "Bither" supports Bip39. (though not really sure about this). You could try either mycelium if you are going for a mobile based wallet that supports Bip39. Summarising these,

[1] Hardware Wallets
  • Ledger Nano S
  • Trezor

[2] Desktop Wallets
  • Bither
  • Electrum (you could import Bip39 seeds in them)

[3] Mobile Based Wallets -Android
  • BRD Wallet
  • Mycelium

[4] Mobile Based Wallets - iOS
  • BRD Wallet

No, you need to learn cryptography if you are going to learn about Blockchain. Cryptography, Peer to Peer Technology are the building blocks of the blockchain technology.
