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

[tacotime]

For the sake of clarity can we eradicate all references to bitmonero now? I see some instances on github and elsewhere still using the old term.

This will be changed in the coming week as we move to monero-developers on github.

payments command allows you to see the transaction, height, amount etc by using just the payment id. Useful to track a payment you are expecting as there is no way to use the block explorer in the same way as BTC.

How does the system ensure that the Payment ID is unique ?

i.e. what's to stop me from entering any old non-unique payment ID like "hello" ?

It doesn't. You can re-use same payment id as many times as you like.

ok - so the payment ID is just a kind of user annotation on the transaction. Presumably then I can add it even if it isn't needed at the other end but if an exchange specifies one for deposits then I must use their specified one.

Is that it ?

On top of all that, I've already lost about 100 XMR because I transferred exchange to exchange 'the normal way' and it's now disappeared into the 'ether'.

Provide the exchange with txid and I'm sure they will help you out. If you withdrew from cryptonote exchange I'm able to provide txid if you contact us by support ticket and provide amount and address. I had quite a few contact me about this, it appears to be a pretty common mistake unfortunately. Perhaps poloniex should increase the font size of the warning and make it red

Yup plus one to that, something tells me they don't mind non referenced payments though as people seem to give up on some things quite easily.

In my opinion they should do what you did, thats the perfect way to help the noobs out, you cant go wrong with copy paste.

Yep. The exchange assigns a payment id to a user and when payment is incoming to that payment id they will know which user to credit. All users send payment to the same monero address, so there is only one way to know who sent the funds, and that is using payment id.

Exchanges use it to link a particular payment to your account, but there are probably many more applications. It's really just a small piece of data you can attach to a transaction.

Yes. You should use unique payment IDs each time, otherwise your tx will become linked together.

Same computer, QCN and FCN is OK, but MRO fail to connect.

We need more seed peers. Ask someone here for their p2pstate.bin files.

I have the same problem. Does it help to wait or is it essential to get a up-to-date p2pstate.bin file from someone?

Guys, im sorry to repeat the question but im stil not getting any peer connection. If that p2pstate.bin really helps could someone send it to me pls? Or perhaps its a better idea to set a link to the up-to-date file into the main post of the thread.

Im sending you a link to my dropbox in a PM, give me 5.

The latest github repo has all new seednodes in it.

Alternatively, please start the daemon with the following flags:

bitmonerod --seed-node 62.210.78.186:18080 --seed-node 195.12.60.154:18080 --seed-node 54.241.246.125:18080 --seed-node 107.170.157.169:18080 --seed-node 54.207.112.216:18080 --seed-node 78.27.112.54:18080 --seed-node 209.222.30.57:18080 --seed-node 80.71.13.55:18080 --seed-node 107.178.112.126:18080

ok - great.

You guys have been really helpful considering my slightly antagonistic post earlier.

Much appreciated.

Thank you. That seem to work. At least hes downloading the blocks now.

Is that it ?

Yes. You should use unique payment IDs each time, otherwise your tx will become linked together.

You mean they'll be linked together from the exchange point of view?

What is the maximum length of the payment ID? Is it long enough to provide a monero address?

You will be able to search the blockchain after for all tx that have that payment ID, because it's cleartext. Of course, it doesn't necessarily mean tx are related, but if you keep using the same ID to send to the exchange...

256-bits.

I was just about to ask this same question

[giveBTCpls]

How do I calculate the amount of XMR I can make mining given my hashrate? I want to know if it's worth it for me or not.

GPU miner is pretty simple to use, take a look at the https://bitcointalk.org/index.php?topic=638915.0 thread

Note that is for Windows 64bit with AMD cards only, I hear that an nVidia miner is coming but not yet.

Sample .bat file for mining with the GPUminer is simple, there arent any parameters to adjust except the pool and your wallet address

set GPU_MAX_ALLOC_PERCENT=100

That is tremendous!

1) Is it known whether this will play nicely with 10.8?  I can't run the binary because I have installed homebrew and somehow unsuccessfully uninstalled macports, and now my computer won't recognize that the right version of boost is sitting right there.  I'd love to be able to take my coins off the exchange without saturating my hard drive (and RAM) with a VM.

2) Is mropool trusted - can anyone vouch for them?
