They can reach out to me @ dev.mc2@gmail.com if they need help too (it doesn't look easy contacting them)

It's a Russian company so I'm not sure how easy it will be to communicate with them but I submitted a ticket giving this contact info.

thank you

Synching this blockchain takes quite a while, even this soon after release.. Makes me wonder how bad it will be later on. Hhopefully some improvements can be made, (parallel downloads?). Looks like this fork also stores the entire blockchain in memory? Anyway, new-ish technology is exciting, gonna try mining some.

Yes, it loads the entire blockchain into memory.  This is a problem with ByteCoin too.  The reference implementation is pretty immature.

Syncing the entire blockchain takes a while too because you need to hash each header to verify it, and most single cores of a CPU only do 1 H/s or so.

Looks like solo is still fine even at diff 260k -- even with a single modern quad you should still be getting a few blocks per day. Smiley

I think probably solo will be dead around 750k for unix users, but we will have pools up by then.

Grin Patiently waiting my dear friends.

Stuff is mostly finished up with what I had to take care of.  Returning to full time work on this and part time work on Bitmonero this week.  Should have some updates on code by Sunday/Monday over BitMessage if all goes well.

We should probably fix the mempool/getblocktemplate at some point to not include ALL transactions at the cost of the block reward

Code:
2014-Apr-21 23:51:41.291710 [P2P5]+++++ BLOCK SUCCESSFULLY ADDED
id: <d4c9d4da7ef4fa8ec3e9af41b46e8fa4496c04161ee481da7a9d6020af294097>
PoW: <8bd14baabe4f4f8f285db52e68c4e2d785c04b9f3277e912e1c0fed7f7120000>
HEIGHT 5812, difficulty: 233194
block reward: 2.167697195560(2.167696060291 + 0.000001135269), coinbase_blob_size: 345, cumulative size: 38720, 959(1/609)ms

If I was that miner I would be pissed.  You should be able to set a max inclusion for transactions from the mempool in bytes somewhere.

If you read the original paper, the miner is supposed to strive for the maximum reward + transaction fees. I guess the code doesn't do that?




This is the idea case, but you're only supposed to increase block size slowly to avoid reward penalty such as was seen in that block.

You need to alter this function to avoid making blocks larger than 10 kb without necessary fees to incentivize addition to the network:
Code:
 bool tx_memory_pool::fill_block_template(block &bl, size_t median_size, uint64_t already_generated_coins, size_t &total_size, uint64_t &fee)
  {
    CRITICAL_REGION_LOCAL(m_transactions_lock);

    total_size = 0;
    fee = 0;

    size_t max_total_size = 2 * median_size - CRYPTONOTE_COINBASE_BLOB_RESERVED_SIZE;
    std::unordered_set<crypto::key_image> k_images;
    BOOST_FOREACH(transactions_container::value_type& tx, m_transactions)
    {
      if (max_total_size < total_size + tx.second.blob_size)
        continue;

      if (!is_transaction_ready_to_go(tx.second) || have_key_images(k_images, tx.second.tx))
        continue;

      bl.tx_hashes.push_back(tx.first);
      total_size += tx.second.blob_size;
      fee += tx.second.fee;
      append_key_images(k_images, tx.second.tx);
    }

    return true;
  }

I'll look at it tomorrow

This is not gonna be "the next Bitcoin" unless it's forked to a Myriadcoin type revision.  Four algorithms at 8-10 minutes each:  Groestl, Cryptonote algo, Sha 256, and then either Skein, Heavycoin algo, or X11.

Right now this is just a botnet coin.

lol

Fork would be good. This (Bitmonero) and the other "HoneyPenny" sound both terrible. We need a good Cryptonote based coin that has probably a preannouncement, no premine or at least honest premine, websites registered before launch and a good name like Bitnote or sth. If someone is to create a new fork with these things in mind, I'm supporting.

We can just rename it too, like what was done with PeerCoin.  Some kind of monero or esperanto derivative.

So far the initial distribution is very good -- reminds me a lot of Litecoin.

ByteCoin is technically neither anonymous nor unlinkable -- it's simply designed to provide more privacy for transactions.

Services still needed:
- Official exchange
- Pool and open source pool software
- GUI wallet
- Faucet

I will try to work on GUI as I have time, I'm getting back into doing stuff for MC2

diff is too high now for solo, unless you are a botnet  Grin
that is strange because on bytecoin at diff 600k I could mine ~1 block per day, here diff is only 120k but no block for almost 24 h.
Maybe OP should contact minergate to add BMR pool  Grin

edit: now there is a source for minergate miner https://github.com/amjuarez/bytecoin

Solo should be okay, I have been getting blocks still solo.  May just be unlucky.  Try compiling in ubuntu linux 13.10, you usually get about 3x higher hash rates than windows.

Only 13.10 has the correct dependencies, do not download 14.4!!!

Compile in this way:
Code:
sudo apt-get install libboost-all-dev cmake
cd $HOME/your_bitmonero_directory/
mkdir build
make -j4

May i ask why blocks are so slow? I mean there seems to be not instamine. people didnt bother with the coin or diff changes every block or something? I guess i have to check bytecoins algo...

Difficulty change is per block and adaptive, so there is no instamine.

Bytecoin difficulty appears significantly down from its peak (hanging aroung 800k right now vs a peak around 1200k). Wonder if BMR has interested some of the miners?

Our diff hit 120k last night, so probably.

A block explorer should be easy to make; just query the RPC webserver with JSON requests for the blocks and their contents, then dump that into a database.

To make it not crash I had to downclock memory

perhaps these are sensitive to memory errors (AMD gpus don't do error afaik)

Quote
Once I saw out of memory message, once something like an attempt to write to restricted memory (can't remember the exact wording).
I get both these errors too, downclocking mem to 1300 MHz helps but probably there are memory leaks in the CPU code

windows build this and add pool support so i can add this to guiminer-scrypt already! Cheesy

My comment was not that I feel left out. Rather, I am impressed with the background of cryptonight. I have very limited ability to understand the technology. I very much feel that much of what is written on these forums are beyond me. However the philosophy great.  Some thing that appeals to me. I also feel that there is a great opportunity here that has been missed. You and thankful could have collaborated and brought bytecoin 2.0. A coin that builds onThe previous version. A gui, mac bineries. And accessible windows bineries. The link at the begging does not work.

Those are my thoughts.these, just criticisms and from me who has nothing to Contribute really. I am just impressed with all of this, crypto currency technogy. I can barely understand it.



The forum messed up the link because of its # character. Copy-paste the whole thing and it does work: https://mega.co.nz/#!dIMVWYTI!kHTvcON_liMT-14--iLM6VMK_zv0dYe5mbBxVT8_Cv4

This coin is a work-in-progress. I would've waited for a GUI before release but at this point I think it's proven its legitimacy by fixing a blockchain-killing bug.

another link to the windows binaries is here: https://anonfiles.com/file/557536bff04c9dbb85d290233850873b

difficulty is almost at 100k

I am new to cryptocurrencies. Some of you are so familiar with the process that complicated steps are deemed simple to you. With that said I was able to download and mine bytecoin bcn. As of today I can not download bitmonero for windows. This I believe is  rush job attempting to be first to market and increase profit margin on very early knowledgeable adapters. There was no attempt to move forward cryptonote vision. No attempt to improve on the delivery or execution of bytecoin bcn.  If I can download and mine bcn and cant do the same for bitmonero, this I think implies poor execution. I use myself as a basis because I did not even know what a cmd line was until 3 weeks ago.


you can also follow these simple instructions:
https://bitcointalk.org/index.php?topic=544715

even if you start mining three days after launch you're still in a pretty good place.

Current difficulty is 93367, until we hit 250k or so you should still be able to solo with a good CPU

havent found a block in ~2600  Hashrate 11  :/

You should get at least a few blocks per day... keep mining Smiley
