Is there any, even very very small possibility, that some two people generate the same address and private key using BETA? Is there some checking to not generate the same address?

Have you ever heard of that happening with bitcoin ?
It's the same kind of likelihood i think

I think its not per default the same as btc. It depends on the hash seed and the used rand generator. If this is implemented bad/wrong the possibility of collission could be higher. But we have to have trust in devs for many other things, so this doesnt matter more...

SHA3 should be less prone to this than bitcoin's SHA-256.

REAL NEM COINS???

There is already... in silver and in gold
https://bitcointalk.org/index.php?topic=654845.msg8446629#msg8446629


BTW: what means "9999 pure gold and 999 pure silver" ?
I have thought that eg. pure gold is too soft and a practical purity for gold would be 85 - 93 %.

It means what is written.

.9999 pure gold and .999 pure silver is only minted by a few places.  By industry standards, .9999 gold is 24 karat (24 karat meaning pure gold with miniscule microscopic impurities)

Sure you could get 100% pure gold but first you would have to molt it down and send it flying at the speed of light to remove that .00001% impurity

That 99.99 % was just so high ... 
I was thinking if such gold is too soft for coins and at least 2 carats would have been "sacrified" to make the NEM goldcoin stronger

http://en.wikipedia.org/wiki/Gold
"Because of the softness of pure (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 10k, contain higher percentages of copper or other base metals or silver or palladium in the alloy."

Just don't use the coins to build your house or for self defense. They are strong enough to look at

I get:
"NIS requires to be booted. Please open your wallet and boot a local node via the popup dialog or configure the auto-boot setting."
this is as far as I've been able to get after trying multiple browsers. I previously got other errors.

GUI looks nice (not like the typical altcoin wallet), and I realise that this is beta, but devs should consider a simple, one-click installation/launch process that doesn't require non-techies to install multiple software packages (and concerns/unknowns about the security risks of doing so) and go through lots of hoops/caveats.

There needs to be a bit more of an eye here toward encouraging adoption by a general audience outside the world of crypto.

Okay, I managed to find that option of "Boot local node" but then I get "missing parameter" which I assume means I have to select a node. What do I put into the node field?

We're aware of the "problem" and it will be solved in time. It just hasn't been a priority.

You can type anything. "sdersdf3" for example.

It could happen on the same day that you get struck by lightning, win the lottery, get hit by a neutrino, and have your body ripped apart encountering dark matter.

I thought we get hit by neutrinos constantly it's just that noone notices ? They even had a hard time building a detector for those little buggers.

That did it - thank you. Interface looks really nice.

yeeeeeees works fine now. If anybody is using Ubuntu I reccomend installing chrome and then running NIS and NCC from your machine not webstart. got to localhost:8989 and copy and paste away

Yeah you're right. I think about 100 trillion neutrinos pass through your body each second, they just interact very very weakly with matter... As analogies go, that one failed catastrophically

Very quickly doing the maths: each private key is 66 characters long, each entry can be 1 of 36 characters. The total possible number of private keys is therefore 36⁶⁶ which is a staggeringly huge number; 5.2 x 10¹⁰². The likelihood of someone generating the same private key as you is vanishingly small - small enough to treat as 0.

[rockethead]

The standalone version WORKS. I get to the "Create new wallet" etc screen.

The thing is AFTER i'm running this standalone version I run the webclient/NOM after this/simultaneously and it goes past the last line (the "SEVERE could not acquire bla bla bla")

Edit: I think there's a facepalm in order. The .jar standalone v NCC should be running all the time?
Edit2: nah, shutdown everything and ran just the webclient again and it works fine (no "SEVERE" errors)
Edit3: sometimes both versions work and sometimes they don't (SEVERE...) and not sure about the cause/effect relation

Check your HDD. It could be bad sectors...I am not sure. But it could be the inability to write something. It looks more like a mechanical error than a systematic software error to me.

If the software doesn't work, it will never work unless you fix something.

That number is larger than the number of atoms in the known universe.

A private key has 256 bit meaning there are 2^256 ≈ 1.1579 * 10^77 different private keys. A collision will not happen

why when i open my wallet ,it always said:NIS requires to be booted. Please open your wallet and boot a local node via the popup dialog or configure the auto-boot setting.??

go to settings and go to boot node.. then enter what ever name you like. you can also select "auto-boot node on launch" which is very handy.

[BitcoinForumator]

Rockethead, I doubt it's bad drive. It's an SSD and I checked it a few weeks ago and it worked fine. The important thing is that it worked many times and it looks like it will work sufficiently enough in the future. I lack the will to pinpoint it right now and it looks like it will require some more heavy pinpointing. Smaragda's proposal worked somehow and that's cool for now. Thanks for the help to all.

not house, tho  
Very pure gold has, ofc, its benefits: if someone tests if it's genuine gold, he will not break his teeth

Good math, but your assumptions are not quite correct. It's actually a 64 digit hexadecimal number, so 256-bit, just like most BTC private keys. BloodyRookie above has it right; it's a significantly more likely, but still vanishingly small chance.

Base-36 wouldn't really be used anywhere that I know of. BTC WIF uses Base-58 for example, but "raw" private keys would typically be represented as hexadecimal as here.

Good to know NEM is so strong.
