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

Exchange.I2P Darknet CryptoCurrency Exchange : https://bitcointalk.org/index.php?topic=1092682

According to this Monero isnt going to be listed. At least at the start.

His reasoning can be found below. Perhaps one of the XMR core devs can inquire further and find a solution:

"The issue with cryptonote coins is that the server must run a node anonymously. Bitcoin based altcoins can be run over tor, monero etc cannot. This increases the risk of demasking."

Run your node inside whonix or another torified VM

If you don't have the technical expertise to set this up, I'd question whether you should be running a "dark" exchange at all..

Yo, thanks for the link. I asked in IRC #monero-dev and nobody really had any experience doing it. I had tried to force it to run via torify and it was giving exceptions that i pasted there. I will try to fuck around with it a bit more when i have time and see what happens.

Try again during daytime (talking about GMT - GMT+2 timezone here), most devs are online during that time, so I think you'll get a better answer then.

From reddit:

Monero Proof for your timestamping needs

Sorry I posted this a couple of times in the past hour, the first time I accidentally deleted it, and then it used the suggested title which I didn't want. In any case, if you need to hash and timestamp a file on the monero blockchain you can use:
https://github.com/ShenNoether/MiniNero/blob/master/MoneroProof.py

Note that I have only tested this on a few files I needed to hash, example file hash sent:
http://chainradar.com/xmr/transaction/8d3cd06528f92194a8f296ef6e08c5a820c3fef0a525b4d46752d58295b7503e

So I wouldn't send more than the trace amount needed for hashing to these address it generates.

I just tried running vanilla bitmonerod with torsocks and I can sync fine. I'm getting failed connections after syncing though, but this is encouraging as I think most/all of the net code goes through the same lib (epee).

I might have a go at seeing what's going wrong depending on time available.

Here is the error im getting.

What version are you running (git commit hash) ?
Modified or not (I don't see a hash with "b566" in my tree) ?
That "Starting..." message is only in the blockchain conversion utilities on my tree (master from yesterday), which seems odd.

[argentinx]

i have compiled monero for windows
the problem is that
I stand for 2 days and I came only to 170 thousand
How long does it take to download all blockchain?
I do not seem normal

You should download the blockchain separately.

how?

If you run your Wallet over TOR you should not experience heavy problems. Maybe some exits can not connect to peers, but they change -circuits- by default every 10 minutes. Everything in TCP can be tunneld trough TOR, UDP only DNS queries.

If you run a miner over TOR, i think the frequent latency change due to the exit change will give you some troubles. I do not run a miner over TOR, but i can setup one 

[elrippo]

how?

https://getmonero.org/downloads/

[argentinx]

in that site there is the bin file
i have compiled the last version of monero
that use the lmdb database
and the converter dont work
at the end of conversion
the generated file was clobbered
and bitmonerod download blockchain from 0

Could we get a message from the devs whether they assess that it is currently safe to transact if privacy is of importance or wait until the hardfork(s)?

[entertheabyss]

Its the newest clone from the master branch and compiled with build-debug option.

Now, this is hilarious. I had this... can't be that... moment...

But it is. You are using the original bitmonero fork from TFT

About as safe as a piece of string is long, I'd say.

Now, if you have a more precise question, a more precise answer might be found.

That looks more like expected.
The first set of errors are for UDP, I believe.
The second one, about binding, I do not get here. Though I'm surprised it binds to 0.0.0.0, it should bind to 127.0.0.1. I tried setting 0.0.0.0 and it still works fine though. Does it work without torsocks (I guess you can pull the network cable to make sure nothing monero goes out) ?
In any case, a strace log would let us know what syscall is failing, and with what error.

LMDB still won't work because the LMDB design requires 64 bit. There is an experimental branch of LMDB called VL32 but that is likely never going to be a great option because the developer says "I am philosophically opposed to supporting 32 bit architectures in LMDB." and "Due to the added system calls involved, it is significantly slower" and "Fundamentally, supporting this feature in LMDB is the wrong thing to do." Quotes from http://www.openldap.org/lists/openldap-technical/201501/msg00127.html

At this point the best approach for 32 bit embedded is going to be BDB, although in the future there might be an even better option (BDB has some issues, but at least the implementation exists). On RPi2 it serves as a nice (successful!) functional test is still likely too slow to ever actually use. Some work has been done to optimize it, mostly by NoodleDoodle.

Thanks smooth for your reply!

[kazuki49]

a "darknet" exchange without any cryptonote coin sounds like a big red flag to me, its funny people complain about polo and the KYC trap but Monero (and the other cryptonotes) are the only coin that protect individual privacy even in these cases, sure they can know how much you bought and what is your address but thats it, using a darknet exchange will not make any bitcoin clone fungible.
