Hi,

Is there any cheap VPS for a new created altcoin node ?

With minimum 10/20 GO space.

Thank you

The first goal of cryptos is to be anonymous ! and all cryptos will go at this way in the futur ... even bitcoin with the introduction of shnorr etc....

Who can stop crypto ? everyone is confortable with that ... even govs of the world are satisfed ... they just create laws for some reasons.
46  Alternate cryptocurrencies / Altcoin Discussion / Re: Monero, Zcash, and Dash Could be worth ZERO soon! on: May 08, 2018, 12:53:06 PM
Purhapse for others but i don't think DASH will discrese ... it's growing each day.
47  Alternate cryptocurrencies / Altcoin Discussion / Re: Technical questions about premine ? on: May 08, 2018, 12:51:03 PM
The coins awarded in the genesis block for BTC are not spendable. Since most coins are a fork from BTC, the genesis block reward would not be spendable for those coins as well. I'm not sure if any coins corrected the code for their coins so that the genesis block reward is spendable.
Since the starting difficulty is rather low when a coin starts out(you can set the minimum difficulty in the code. with BTC, I believe it was 1), the dev can usually just solo mine the 1st block in a short period of time.
Please can you show me the line of code please ? and what value it will get in order to be low difficulty ?

How much time it will take to premine it ?
48  Alternate cryptocurrencies / Altcoin Discussion / Technical questions about premine ? on: May 07, 2018, 11:30:18 PM
Hi,

Do genesis block spendable ? if yes, why other altcoins use the block 1 instead of genesis block to premine ?

How much time do AUROCOIN, CANADACOIN or other countrycoins took time to premine that amount of coins ?

Some members will say just to change the block reward difficulty, yes but programmatically where and how to do that ?

For example:

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;
    if (nHeight == 1)
        return 10500000 * COIN;

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

Here we set 1050000 coins for the first block, but how to get all that coin to a newly generated address ?

Do i have to use a miner or a fast method to get them there in no time ? if i use a miner, how time this will take to get them all into my wallet ?

The last question is, if i premine about 80% of max money supply, do this algo will be ok for the new altcoin or you can give a suggestion for it:
Code:
    CAmount nSubsidy = 50 * COIN;

    if (nHeight < consensusParams.nSubsidySlowStartInterval / 2) {
        nSubsidy /= consensusParams.nSubsidySlowStartInterval;
        nSubsidy *= nHeight;
        return nSubsidy;
    } else if (nHeight < consensusParams.nSubsidySlowStartInterval) {
        nSubsidy /= consensusParams.nSubsidySlowStartInterval;
        nSubsidy *= (nHeight+1);
        return nSubsidy;
    }

    assert(nHeight > consensusParams.SubsidySlowStartShift());
    int halvings = (nHeight - consensusParams.SubsidySlowStartShift()) / consensusParams.nSubsidyHalvingInterval;

    if (halvings >= 64)
        return 0;

    if (nHeight == 1)
        return 10500000 * COIN;

    nSubsidy >>= halvings;
return nSubsidy;

Hope i will get some answers from experimented users.

50  Alternate cryptocurrencies / Altcoin Discussion / How the Bitcoin Private pubkey prefix is generated ? on: May 06, 2018, 06:05:22 PM
Hi,

I noticied that bitcoin private contain two bytes !

Code:
        // guarantees the first 2 characters, when base58 encoded, are "b1"
        base58Prefixes[PUBKEY_ADDRESS]     = {0x13,0x25};
        // guarantees the first 2 characters, when base58 encoded, are "bx"
        base58Prefixes[SCRIPT_ADDRESS]     = {0x13,0xAF};
        // the first character, when base58 encoded, is "5" or "K" or "L" (as in Bitcoin)
        base58Prefixes[SECRET_KEY]         = {0x80};
        // do not rely on these BIP32 prefixes; they are not specified and may change
        base58Prefixes[EXT_PUBLIC_KEY]     = {0x04,0x88,0xB2,0x1E};
        base58Prefixes[EXT_SECRET_KEY]     = {0x04,0x88,0xAD,0xE4};
        // guarantees the first 2 characters, when base58 encoded, are "zk"
        base58Prefixes[ZCPAYMENT_ADDRRESS] = {0x16,0xA8};
        // guarantees the first 2 characters, when base58 encoded, are "SK"
        base58Prefixes[ZCSPENDING_KEY] = {0xAB,0x36};

How is that calculated ?

Thank you in advance.

So, it's good starting but this actual idea go nowhere.

Did you learned about Bloom Filter ?

It compress the blockchain to have approximativally 300Mo (This is a good solution for the problem).

Could you please provide more details on how bloom filter can compress blockchain?

You can find more infos here:

53  Bitcoin / Development & Technical Discussion / Re: What IDE used for Bitcoin developement (Ubuntu) ? on: April 28, 2018, 06:54:36 PM
everyone at our startup uses visual studio code or atoms
Visual Studio under Windows no ?
54  Bitcoin / Development & Technical Discussion / Re: What IDE used for Bitcoin developement (Ubuntu) ? on: April 27, 2018, 09:32:51 PM
Most people who work on Bitcoin Core do not use an IDE. Many just use a text editor (such as emacs or vim) and the terminal. All of the build commands are documented and it is not difficult to copy and paste commands into the terminal.

Only peoples that compile only the source that use command lines.

But what about making changes on the source code ?

IDE is a good way to debug the code, retreive errors etc.

Hi,

What IDE used for Bitcoin developement on Ubuntu ?

For fast compilation, error logs, etc.
56  Bitcoin / Development & Technical Discussion / Re: Is it possible to use Bitcoin Blockchain for Litecoin ? on: April 25, 2018, 08:49:55 PM
But they not explaign more my goal !

I am not willing to create new altcoin, just to understand the process to update Litecoin source code to use the Bitcoin Blockchain.

What files must be modified etc.
57  Bitcoin / Development & Technical Discussion / Re: Is it possible to use Bitcoin Blockchain for Litecoin ? on: April 25, 2018, 08:29:25 PM
But what is the approach i will take to make this happen ?
All this theorically of course.

There is a thread (from 2013) here on the forum by fisheater which describes the way of forking and creating an altcoin pretty detailed.
It suits well for research purposes (creating own altcoin, blockchain, genesis block, ... ).

Great article !

Thank you for your contribution !

It's like a ransomware friendly software for commercial use !
59  Bitcoin / Development & Technical Discussion / Re: Is it possible to use Bitcoin Blockchain for Litecoin ? on: April 24, 2018, 11:43:54 PM
I just read it, but it's not exactly my goal here Smiley

My request is a kind of HARD FORK, manage for example Litecoin source code to use Bitcoin Blockchain where everyone get the same amount of coins they possess at a certain block.

If it's not possible with Litecoin, is it possible for any other ALTCOIN based on Bitcoin core tech.

Thank you


Well, you could make a Bitcoin hardfork that uses the same metrics as Litecoin (ie. same PoW algo, block reward, block interval, etc...)

However such a coin would be neither Bitcoin nor Litecoin -- it would just be a Bitcoin hardfork using the same metrics as Litecoin.

Either way, not sure how much Litecoin's codebase has diverged from Bitcoin's ever since the code got forked -- after a lot has happened since then -- but it's likely still one of the technologically closer alts (apart from more recent hardforks, of course).

Nice infos ! But what is the approach i will take to make this happen ?

All this theorically of course.
