There's a bug inherited by all CryptoNote coins where a transaction gets stuck in the tx_pool because of disagreements between the wallet and daemon. When this happens, your tx fails and doesn't show up on the blockchain, but you start seeing spent key image errors when trying to spend again. This will be fixed in the next release, but for now if you want to send large amounts, do it in batches less than 100 MRO.

Do you think lost coins can be found in the future?

They're not lost. A transaction can only spend a limited amount of time stuck in tx_pool. You should be able to send successfully after some time with a fixed wallet.

For those of you on Win 64, I think I managed to get your hashrate closer to that of the *nix implementation. Haven't tested it, I don't use Windows.

I have a stupid question, sorry Smiley

If a transaction was made and the software registered the transaction hash, does it mean it can be included in some block in the future when it finds enough other recipients, it doesn't have to be the next block, it can be many blocks into the future?

EDIT: or is it the same bug that GreekBitcoin posted below my post?

Your comment just made me think Smiley Since the transaction was nowhere to be found except my logs and i didnt have the coins on my wallet all i had to do was to replace with a backup of my wallet before the transaction. And that solved the problem!

Thanks!

P.S. i had also deleted and redownloaded the blockchain...

It makes sense that an old wallet.bin wouldn't think the keys were already spent. But I think in Noodle's testing, he found that a sync directly from the .keys file didn't fix the problem. That maybe indicates a deeper problem, but we're really not sure. tacotime will look into it later today.

i mine there from my mining start 3 days ago and i see we get paid at some time of day, not every hour. I guess that is how it is, like someone has to print stamp on transaction.

Hi again,

does someone tried this "merged mining" of BCN, MRO and QCN with this Fantomcoin (FCN) ?

coins per day = blocks per day * block reward = (hashes per day / difficulty) * block reward =

(hashes per second * 86400 * block reward) / difficulty

or with current parameters

estimated MRO per day = hashes per second * 0.00779949346

Hi all, I have some basic noob questions.

I have installed and synced the Windows 64-bit binaries. I have simplewallet.exe running.

my intention is to mine, and maybe buy a few MRO,

Mining First
1) address command> returns a long alpha numeric string starting with "4" is this a public address, in Bitcoin language?

2) is this the address I mine to?

3) is there only 1 address per wallet? can I add addresses, or do i create new wallets?

4) for code storage, is there such a thing as a private key, or how do I create cold storage?

5) what is a View Key?

your help welcome,
thanks.

Thank me in Bits 12MwnzxtprG2mHm3rKdgi7NmJKCypsMMQw

I looked at mining algorithm and I see that pow is calculated over WHOLE block (sha3). Not block header like in bitcoin, but whole block with transactions. Is that true or am I mistaken?

If that's true this means that ignoring transactions gives a small speed boost in mining. That's not very good for the future...

- on all these UNIX tuts on monero.cc, I would add "--no-check-certificate" parameter to all "wget" commands
- the debian script needs: "apt-get install python-software-properties" added, as the used "add-apt-repository" command is not installed default

So I've been buying up some MRO at the current low, and I've been watching it closely from its beginnings. The market is doing some unusual things, and I have a tentative analysis. I believe the buy pressure is not being adequately represented in its price movements. I suspect this is because of a combination of two factors:

1. A large proportions of the hash being from botnets (where the operators immediately dump), and
2. The relatively high emission rate.

This creates a disproportionate downward pressure on price that differs from other coins, and which appears to be consistently outstripping buy pressure, despite strong interest in the coin. This is not a good thing, and it may drive the price into the ground. Without the expectation that the price will go up, fundamentals don't matter a bit. Miners and investors will lose confidence and move on.

There is a solution to this: write a GPU miner. In its current form as a CPU only coin, if the MRO market doesn't ramp up buy pressure to consistently match/exceed the expected constant dumps from botnets, the coin will fail. And it's easier to scale up botnets than it is to scale up the ordinary userbase, so this disparity may worsen. Your average GPU miner is more likely to hold than your average botnet operator who's looking for immediate turnover and who doesn't care if the coin lives or dies. Perhaps equally importantly, a GPU miner would massively increase adoption among the community, which is another thing currently holding MRO back.

I know people here may be currently enjoying nice profits from CPU mining, and may not appreciate the suggestion of a GPU miner. Personally I'm more concerned about the longer term future of the coin, and I think Monero has a vital role to play within the anonymity niche. Its fundamentals are good and I'd like to see that reflected in its market performance. I'm willing to put a good chunk of MRO towards a bounty for an open source GPU miner if there's enough support for it.

1) Yes this long string is your address
2) Yes, you can mine without opening the wallet by typing on daemon     start_mining  yourwalletaddress numberofthreads. Thats for solo mining...
3) Yes there is only one address but you can make more wallets and i personally run at least two on the same daemon. I think there arent problems with that but i am not sure.

better others asnwer for 4 and 5
