[ANN] Dpowcoin- Dualpowcoin - Dual PoW (Not Multi POW!), NO-Premine.

[mraksoll]

Dpowcore - Dualpowcoin





What is this ? Another Altcoin ? Maybe but read next.

This is experemtal coin with dual pow , dual Pro of Work - not multi Prof of Work!

For each block, 2 proofs of work were used - first we verify the block with the first POW - Yespower, then we verify the same block in 2 rounds of SHA512 as salt and 2 rounds of Argond2id, and the block is valid if it passes both proofs of work

Code:

static bool CheckBlockHeader(const CBlockHeader& block, BlockValidationState& state, const Consensus::Params& consensusParams, bool fCheckPOW = true)
{
    // Check proof of work's matches claimed amount (dual pow logic)
    bool powResult1 = fCheckPOW ? CheckProofOfWork(block.GetYespowerPoWHash(), block.nBits, consensusParams) : true;
    bool powResult2 = fCheckPOW ? CheckProofOfWork(block.GetArgon2idPoWHash(), block.nBits, consensusParams) : true;

    // Checking if both POW's are valid
    if (!powResult1 || !powResult2) {
        return state.Invalid(BlockValidationResult::BLOCK_INVALID_HEADER, "high-hash", "proof of work's failed");
    }

    return true;
}

Get PoW Logic

Code:

/* Yespower */
uint256 CBlockHeader::GetYespowerPoWHash() const
{
    static const yespower_params_t yespower_1_0_dpowcoin = {
        .version = YESPOWER_1_0,
        .N = 2048,
        .r = 8,
        .pers = (const uint8_t *)"One POW? Why not two? 17/04/2024",
        .perslen = 32
    };
    uint256 hash;
    CDataStream ss(SER_NETWORK, PROTOCOL_VERSION);
    ss << *this;
    if (yespower_tls((const uint8_t *)&ss[0], ss.size(), &yespower_1_0_dpowcoin, (yespower_binary_t *)&hash)) {
        tfm::format(std::cerr, "Error: CBlockHeader::GetYespowerPoWHash(): failed to compute PoW hash (out of memory?)\n");
        exit(1);
    }
    return hash;
}

// CBlockHeader::GetArgon2idPoWHash() instance
// -> Serialize Block Header using CDataStream
// -> Compute SHA-512 hash of serialized data (Two Rounds)
// -> Use the computed hash as the salt for argon2id_hash_raw function for the first round
// -> Call argon2id_hash_raw function for the first round using the serialized data as password and SHA-512 hash as salt
// -> Use the hash obtained from the first round as the salt for the second round
// -> Call argon2id_hash_raw function for the second round using the serialized data as password and the hash from the first round as salt
// -> Return the hash computed in the second round (hash2)

uint256 CBlockHeader::GetArgon2idPoWHash() const
{
    uint256 hash;
    uint256 hash2;
    CDataStream ss(SER_NETWORK, PROTOCOL_VERSION);
    ss << *this;
   
    // Hashing the data using SHA-512 (two rounds)
    std::vector<unsigned char> salt_sha512(CSHA512::OUTPUT_SIZE);
    CSHA512 sha512;
    sha512.Write((unsigned char*)&ss[0], ss.size()).Finalize(salt_sha512.data());
    sha512.Reset().Write(salt_sha512.data(), salt_sha512.size()).Finalize(salt_sha512.data());
   
    // Preparing data for hashing
    const void* pwd = &ss[0];
    size_t pwdlen = ss.size();
    const void* salt = salt_sha512.data();
    size_t saltlen = salt_sha512.size();
   
    // Calling the argon2id_hash_raw function for the first round
    int rc = argon2id_hash_raw(2, 4096, 2, pwd, pwdlen, salt, saltlen, &hash, 32);
    if (rc != ARGON2_OK) {
        printf("Error: Failed to compute Argon2id hash for the first round\n");
        exit(1);
    }
   
    // Using the hash from the first round as the salt for the second round
    salt = &hash;
    saltlen = 32;
   
    // Calling the argon2id_hash_raw function for the second round
    rc = argon2id_hash_raw(2, 32768, 2, pwd, pwdlen, salt, saltlen, &hash2, 32);
    if (rc != ARGON2_OK) {
        printf("Error: Failed to compute Argon2id hash for the second round\n");
        exit(1);
    }

    // Return the result of the second round of Argon2id
    return hash2;
}

As example for Light SPV wallets can be used only one of that POWS for verify ( sha512+argon2id best in that cases as libs available almost at all plaforms)




How much Premine  have ? the first 3 blocks with a 50 reward for  creating a checkpoint after force BIP's activations . (so there is no premine, no development fee, no delayed mining or whatever they like to call it)

Miners can simple donate some part of mined coins to dev's  if they want -  you can find donate addreses at website.

How to mine ?

go to debug console and put command

Code:

generatetoaddress nblocks "address" ( maxtries )

Example for infine try

Code:

generatetoaddress 10000 "Myaddress" -1

nblocks must be positive value , sorry.

The project was largely created in response to the increasing spam of sha256 coins and a scrypt with abnormal premine.


IMPORTANT !

We do not use "delayed POW" technology and are not related to komodo projects! We use double PoW or Dual POW!

Where can I find the whitepaper?

Can you provide some addnodes?

asnwer to all why is there exist faster blocks

there was no difficulty retargeting for the first 576 blocks, they are needed for LWMA to work correctly as the window it looks at to control diff, and we decided to allow people to mine these blocks rather than mine them themselves, since even with powlimit diff it could take a lot of time and could be regarded as a premine...

you can see in the block explorer that the difficulty started changing from block 577

code lines to see where it is..

Param windows of lwma 576 by recomendation of diff algo cretator for keep stable diff.

https://github.com/dpowcore-project/dpowcoin/blob/master/src/kernel/chainparams.cpp#L88

recomendet give away blocks , for it work correct ( return Powlimit at before block 577 )

Where is there a pool? And is there a need of a new miner to 'dual PoW' mine multi-algo at once?

[mraksoll]

if you need find nodes for add , if for some reason you cannot take it from node or dns seeder

Need create new miner and add to pool this new logic.
Not this is not multi algo coin, there 2 algos for one block - 2 validation stages when we first valid at yespower and if block valid then we try valid this block at argone2id 0x13 , and if 2 algos hashed < target , we flush to data block (as sha256 for fast sync) and send it  to network.

you can see for every block they hashes at algos by ( sha256 there not used for verify blocks only for store them and fast sync)

“无预挖” “可以视为预挖” 577 ，糊弄鬼呢吧！ 我2台电脑SOLO 24个小时一个块都没有，我朋友3个块，但两个块确认失败，全部到持币量第一的钱包地址，到发帖时持币量第一的钱包地址持币量占比超过51%没有？  要不你自己攻击一下自己？ ！

use your brains, if these blocks were mined by the developers, then the release would be after these blocks.

[elmo40]

well, i get 0 blocks when using your generatetoaddress command. My CPU is doing nothing.
plus, i have 0 peers when doing getpeerinfo, and yet my wallet syncs. wtf?

As per standard crypto rules... someone has figured out how to mine, and isn't telling anyone else, and yet difficulty is on a steady increase. Go figure.

rplant  pool  create cpu miner and add it to pool... so you can use standart miner now.

Will a GPU miner be released?

[galllotech]

Hi fellows just came to drop this tutorial for windows mining

[mraksoll]

Will a GPU miner be released?

I don’t think that in the near future anyone will be able to create a gpu miner, considering that 1 of the algorithms is yespower and the second is 2 rounds agron2id
