Topic: [ANN][BURST] Burst | Efficient HDD Mining | New 1.2.3 Fork block 92000 - page 591. (Read 2171061 times)

Is it possible for anyone to jump on skype and help me out? Maybe even Teamviewer.

Because all of this is a bit hard to understand.

If I see it right, burst.ga is down again

How about that for mining on USB 3.0? U;tra low power, and up to 8gb RAM

Hehe, just came across it and want to give it a test some time, just for fun I mean, they HDD's will be wwaayy bigger than the actual PC!!!

EDIT: 4 USB 3.0 ports + 1 sata III http://www.newegg.com/Product/Product.aspx?Item=N82E16856173102

Limit i guess is the CPU for reading all those plots

No ideas.


If you're on Windows, download Janror's cpu plotter. Choose plots ranges so they don't overlap.
Choose stagger depending on available memory, the higher the better.
For example, having 16 gb memory I've plotted 1 tb hdd with the following params:
plot size 400000 (100 gb per file), stagger 40000 (10 gb per chunk)   - this requires ~10 gb ram during plotting

file #1: start nonce 0, plot size 400000, stagger 40000
file #2: start nonce 400000, plot size 400000, stagger 40000
file #3: start nonce 800000, plot size 400000, stagger 40000
and so on
file #9: start nonce 3200000, plot size 400000, stagger 40000
and to fill the remaining 50 gb:
file #10: start nonce 3600000, plot size 200000, stagger 40000

Next HDD will start from nonce 3800000.

Size may vary a bit depending on HDD manufacturer. You might need to adjust the last file size.

Plot size must be a multiple of stagger.

There's also plot file optimizer which can make the stagger equal file size after plotting.
If you use closed-source tools make sure to send the coins often to another wallet which you never store on the PC where you've runned these tools.

Check this out Hamuki, just make sure you use the latest wallet version

So my rig is almost ready..

I just need to know how I plot on multiple harddrives.

I have 6 1TB disks in my computer that is ready for mining, but I have no idea on how to get started with plotting each of them.

Can someone help???

Anyone figure out what happened with all those people getting hacked?  Anyone figure out what happened?

We're not going to end up with an exchange losing a whole bunch of coins and someone flooding the market, are we?

set  "Debug": true,

Blago/anyone - I am using your latest miner.  The older miner used to tell me how many seconds it took to read a folder of plots, but now it does not.  Am I missing a setting in order to get this information? thx

I just voted

The signing issue isn't due to integer size differences, but due to java's lack of unsigned integer types. The proposed patch on the page you linked has been applied to the Curve25519.java file, so this hasn't been an issue for quite a while.

Regarding the passphrase generator, I don't know where the cut-off would be for considering it bruteforceable, however 105 bits does seem very low compared to what you would get from the recommended 35+ characters alphanumeric with symbols.

I think you're looking at the wrong account. Stacy's account had all 9.8k transfered, however they didn't continue to transfer new coins that came in from mining.

I think this is the relevant patch.


Come-From-Beyond claims that there were a number of deliberately-introduced vulnerabilities in the original NXT source code, to deter NXT clones.  It sounds like an incredibly irresponsible thing to do, but there it is.  Supposedly they're all patched, now.  Someone here probably knows the date of the last such patch... the NXT source should be checked for  patches to any vulnerabilities reported prior to that.


People should panic-sell.  Just let me in on the bargain-basement prices. :-)

no news from admin... I don't have any other forms of contact for him either.

I also would like to request if there could be some way to return the "Blocks" section of the wallet back to the old style where newest blocks found were displayed first as it did in pre-1.1.5

I had relied on this more than I thought to see my mined blocks now that its reversed order.

It is down since this morning (GMT)... still no news

Double-check the address you're connecting to.

Any reason for why burstforum is down cant access.

problem was with config, defautl launches successfully

i have'nt looked into the code on how the pk is used to sign transactions but i think it is ecdh based.
doing a google search for the included java code from nxt to do the signing brought up a site stating the sign function is not as secure as the original code where it was ported from to java. this is because java uses different size integers and a c big int variable has only the maximum size of an unsigned int in java (https://gist.github.com/doctorevil/9521116).
someone with java knowledge maybe can verify that the described flaw applies or hopefully does'nt apply to the code in src/java/nxt/crypto/Curve25519.java file or finds out this whole function is only included due to forking reasons.

this in combination with the wallet which offers 12 words OUT OF 1626 by default (html/ui/js/crypto/passphrasegenerator.js) makes it in my opinion attackable.
within an bruteforce attack this is less than 11 bit for each word which sums up to about 105 bits of combinations.
if the ecdh implementation shows the mentioned flaw it cuts internal 256 bit variables at 64 bit.
without further analysis this provides a option to bruteforce wallet generated keys by software designed to utilize this flaw by testing less than 32 bit of combinations. i am no crypto specialist and if someone with knowledge about all this could take a look into it would be great. i think as long as someone uses custom generated private keys even if the flaw exists in the code the required energy to break 105 bits is much more than what you get for the coins in the wallets. on the other hand it may be possible to bruteforce all known wallet addresses in one run without much more costs...

i currently do not understand why someone did'nt empty the whole account and only took 40k.
i dont want to make people panic sell and drive the price down but if you hold a certain amount of coins within one wallet think about all this if you used the wallet to generate your private key.

By random, do you mean randomly machine generated, or chosen manually by you?



It looks like you have recently had security issues.  What steps have you taken to mitigate them?
