[XMR] Monero - A secure, private, untraceable cryptocurrency

[tacotime]

For example if 556.44 XMR are sent, the protocol will break it down into 500 + 50 + 6 + 0.4 + 0.04

Why does monero split amounts to power of 10? Why not power of 2? Are there any differences or trade offs in using different bases for this process?

Good question. Denominations are handled by the code here:
https://github.com/amjuarez/bytecoin/blob/57cf53625817223733bdaf2f4e518ebae978713e/src/cryptonote_core/cryptonote_format_utils.h

Lines 151-190

Code:

  //---------------------------------------------------------------
  // 62387455827 -> 455827 + 7000000 + 80000000 + 300000000 + 2000000000 + 60000000000, where 455827 <= dust_threshold
  template<typename chunk_handler_t, typename dust_handler_t>
  void decompose_amount_into_digits(uint64_t amount, uint64_t dust_threshold, const chunk_handler_t& chunk_handler, const dust_handler_t& dust_handler)
  {
    if (0 == amount)
    {
      return;
    }

    bool is_dust_handled = false;
    uint64_t dust = 0;
    uint64_t order = 1;
    while (0 != amount)
    {
      uint64_t chunk = (amount % 10) * order;
      amount /= 10;
      order *= 10;

      if (dust + chunk <= dust_threshold)
      {
        dust += chunk;
      }
      else
      {
        if (!is_dust_handled && 0 != dust)
        {
          dust_handler(dust);
          is_dust_handled = true;
        }
        if (0 != chunk)
        {
          chunk_handler(chunk);
        }
      }
    }

    if (!is_dust_handled && 0 != dust)
    {
      dust_handler(dust);
    }
  }

The code above makes denomination fairly simple and should generate lots of overlapping outs even without using direct powers of two, but I'm not entirely sure why they chose this above simply using powers of two.

or those of us that encrypt our private keys, it would not make a difference if they were stolen right? the only way to spend coins is with encryption key?

If your password has less entropy than the key, then it is less secure.  English words have 11.82 bits of entropy in bulk, per Shannon.

well sure...my gpu's can crack a 6 character password in 3 hours, but i would be dead before i could crack a ten character. (I always assume the nsA secret squirrels and other prick organizations have much more advanced hardware than people know about, so i make all mine 20 characters). Regardless,

having access to the private keys does not entail ability to spend the coins, correct? I am not telling, I am asking.

it is this way for BOTH bitcoin and cryptonote protocol coins, correct?

  I need your guys help.

I accidentally sent some monero to my poloniex wallet without my payment id and now i need the transaction ID to claim it.

My question is where do I find my log of transaction ID's in the wallet?

Rename your wallet.dat something else like wallet.dat_old and then load your wallet.dat.keys file and refresh. It will list out all the tx you ever made (you may have to log the terminal output).

All the coins add to Mintpal by voted have no future!! Just see enc

I don't think XMR needs to get voted onto mintpal.

The way forwards is to provide user tools..  stuff like:

Multi-address wallet (or simpler front-end to multiple wallets)
Rich list (to verify equitable distribution = important to investors)
Payment gateway
Cart integration (pricing/payment matching to invoice etc)

As long as monero keeps providing the infrastructure, usage will grow.  Mintpal will have been watching the volumes on poloniex, and the fact that they're willing to put it on the vote list indicates they think they can integrate it when they need to.

Rich list (to verify equitable distribution = important to investors)

1. This means nothing with Bitcoin clones, people can store coins at many addresses
2. This is not possible with Monero (It's anonymous  )

First you could try to search your simplewallet.log file for "Transaction successfully sent" or just "sent". The transaction ID should follow.

Do you know what would be the killing feature after I2P integration ?

Decentralized asset exchange.

The first crypto to have these two features will be almighty.

Hi there,

I am trying to compile the source code on Arch Linux 64bit.  I encounter a error due to the boost version installed (boost-1.55.0-6).

Update your boost to required.

I agree to a point, difference being that a lot of the coins that get voted onto mintpal are obvious shitcoins. Monero on the other hand is a quality coin with impressive features that would seriously benefit from having a reliable exchange. Everytime I try and use Polo I die a little inside and we often have people asking in IRC to buy coins so they dont have to use Polo.

Rename your wallet.dat something else like wallet.dat_old and then load your wallet.dat.keys file and refresh. It will list out all the tx you ever made (you may have to log the terminal output).

There is also a simplewallet.log file that should have it.

Made a little script for converting wallet keys to a printable string and back: https://cryptonote.exchange.to/paper_wallet.php

maybe someone will find it useful, should work with all cryptonote currencies..

Sending private keys to internet? No, thanks.

Before you criticize something, read carefully please.

its opensource and the sourcecode is linked, just download and run it yourself.

Having the option to upload your wallet.dat file is retarded. lol

Don't be retarded, download the source or upload an encrypted wallet (i'm not sure which encryption is used so probably better running it on your own server).

And there is no guaranty that linked source is the one that is actually executed on the server.

Where is the guarantee that monero binaries is the actual source code?

So, if the pools are sending dust to small miners, and dust gets eaten in transaction fees, how is this coin supposed to go mainstream. As in if the hashrate went up 10x it would just result in more dust.

Being fixed in the pool code, but meanwhile, mine on smaller pools. Don't mine on a pool where you are much less than 1% of the pool hash rate. 

[David Latapie]

well sure...my gpu's can crack a 6 character password in 3 hours, but i would be dead before i could crack a ten character.

25 GPU, 350 billions passwords per seconds. Your average pro miner can do it and this was two years ago.

Could someone post a link to a more recent record?

Being fixed in the pool code, but meanwhile, mine on smaller pools. Don't mine on a pool where you are much less than 1% of the pool hash rate.

Also mine in a pool closer to your location. Unrelated to dust, but closer = better connection = better effective hashrate = mone monero.

Last night I downloaded the Windows wallet and left it for 6 hours downloading the block chain.

It started at "56 Days behind" and ended up completing.

Then this morning, when I launch the daemon, it starts downloading all over again !! - 56 days behind.

Any ideas why this is happening ?

why dont you download the blockchain from the OP?

ok. I hadn't seen that - I'll try it thanks.
