what's the chances someone could hack those custom addresses (or any other addreses for that matter)

No absolutely not (if you have generated the private key on a offline computer with your own program, and used a good random algorithm)

(brainwallets are "easy" to hack, but that is a completely different story).

As long as your search random (at least as random as your computer allows you) for your public key, then is the chance very small for someone to find the same private key.

When that is said: I am personally very paranoid about my long-term storage private keys, they are all created with physical die's, to avoid the pseudo randomness that all computers have.  

so all i'd have to do is hack your place and time (i.e. take a picture of you rolling the dice, then do a SHA-224 sum of the file) and plug that in the brainwallet

Yes, absolutely.

user account password is VERY weak protection
use truecrypt volume and you have it 100% secure then on password

or use this advice above, to create paper wallet, you can also do it here bitcoinvanitygen.com, i did it



I will recommend to split your saving into different mediums: e.g. one wallet digital stored and a paper wallets hidden away in your safe/locker.

(not to put all the eggs in once basket)

lol, nice

but the question is still how?

you let your gpu run on a script for 15 minute and you found that one ?

This python script works great to generate a pair of puplic/private adr:
https://bitcointalk.org/index.php?topic=361092.msg3866429#msg3866429

It should not be too hard to modify the script to run in a loop and search for a puplic key containing e.g. "unick".
By allowing both upper and lower case, you greatly reduce the time to find the private key.

http://blockr.io/block/info/genesis says the block hash is 000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943

Which one is correct ?

Yep, it block #0 is the one with hash  000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f

I had 0.138 BTC stuck in a tx, they where released today and I also received an email from custommer service as well.

I had no LTC or other types of alts stuck at them.

2471  Alternate cryptocurrencies / Mining (Altcoins) / Re: Network hashrate vs network difficulty on: April 03, 2014, 07:31:37 AM
I don't know the level of detail you are looking for.

The difficulty depend on the block generation speed.

In that sense the difficulty only depend indirectly on the network hashrate.

Each coin has target block generation interval (bitcoin is e.g. 10 min), so if blocks in average is generated faster than 10 min then will the difficulty go up, if blocks in average is generated slower than 10 min, then will the diff go down.

There is a certain amount of hysteresis in the difficulty since it is an average function,  if the network hash rate jumps up, eventually meaning that blocks will be generated faster - then will it take some time for the difficulty to follow. The block generation time also influence on the hysteresis time, there is more hysteresis at 10 min blocks than 1 min blocks.

There is also a certain amount of "luck" involved, since finding a block is basically statistically determined based on the hashrate.

Tyrion,
Any plans on offering new group buy for gridseed and hosted it?
Scrypt coins have more stable difficulty and much profitable to mine, we can hook to a multipool and pay in bitcoin. 

I cannot see how anybody can make a profit by mining with Gridseed unit (at the currently price for the hardware).
If KnC can deliver the Titan as scheduled it will outperform the gridseed insanely (in terms of MHash/$).
Gridseed is 350 KHash/s for aproximate 100$, Knc is 250 MHash/s for 10k$.

Titan can potentially make a profit, but there are many variables and uncertainties to consider.
2473  Bitcoin / Mining / Re: Block #293556 has only one transaction on: April 02, 2014, 02:34:47 PM
Not sure but I think this happens pretty often, I've seen blocks with no transactions at all

Well, there has to be one transaction at least (the block reward).
Thanks for sharing your experience, cheers Smiley

I sent 2 e-mails about 10 days ago, then again same e-mails about 5 days ago. Still no answer, dead like a rock.
It support working on this exchange? Looks like admin of this exchange is completely unreliable and untrustworthy person now. Or maybe I can get comment on this?

BTW my questions to support were just about API, not about recent problems.

I have tried to get a reply from customer "service" since the 3/19 - no answer.

Instead of correcting the funds error issue I've had for more than a week, they took lots of BTC and LTC off my account. and yet I can't withdraw, the error is still there!
this is absurd and extremely fishy.

I am sorry to hear that, I know you also had funds stuck at Vircurex (two hits is worse than one)
I hope you eventually will recover all your loses.

It was found by Eligius so I expected that as much tx fee would be included.
Is this just because there was no pending transactions (with decent tx fee) when the block was found?

@Buffer Overflow have you seen that before, except for block #1 and in the early days?
