Due to scams of several BTC, Wulfcastle is no longer in anyway associated with BURST's community PR Team.

Do not do business with him.


you need to add this to the trust system to protect others



Personally I wasn't scammed, I'm only very angry, but I really hope those who were victims use the trust system, just as you say.

Oh, we will.

a few things

-download page on official website doesnt work and has broken images
-twitter page has no logo or link to main website
-readme.txt contains no instructions beyond telling people how to sync clocks so I can't figure out how to get the wallet running; if I try and run the bat file I get an error saying I need Java despite already having it installed.

as far as the last part goes, you will likely have to change the location that the bat is looking for java, java 8 was released, and the bat was not updated for it...

I.E.

old code in bat...

Code:
@ECHO OFF
IF EXIST java (
start "BURST" java -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
IF EXIST "%PROGRAMFILES%\Java\jre7" (
start "BURST" "%PROGRAMFILES%\Java\jre7\bin\java.exe" -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
IF EXIST "%PROGRAMFILES(X86)%\Java\jre7" (
start "BURST" "%PROGRAMFILES(X86)%\Java\jre7\bin\java.exe" -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
ECHO Java software not found on your system. Please go to http://java.com/en/ to download a copy of Java.
PAUSE
)
)
)


new code changes necessary...

Code:
@ECHO OFF
IF EXIST java (
start "BURST" java -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
IF EXIST "%PROGRAMFILES%\Java\jre1.8.0_31\bin\java.exe" (
start "BURST" "%PROGRAMFILES%\Java\jre1.8.0_31\bin\java.exe" -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
IF EXIST "%PROGRAMFILES(X86)%\Java\jre7" (
start "BURST" "%PROGRAMFILES(X86)%\Java\jre7\bin\java.exe" -cp burst.jar;lib\*;conf nxt.Nxt
) ELSE (
ECHO Java software not found on your system. Please go to http://java.com/en/ to download a copy of Java.

What about https://wallet.burstcoin.io ?
Is it legit ?
Can it be trusted , is it safe to use ?

If I recall correctly, that is uray's online wallet project and is ok.

Wait for more confirmations though, just to be on the safe side that I am not misremembering

Wallet Version 1.1.5 ... i wouldn't use that atm, even IF password is safe.

Damn, uray is in the future Cheesy

On a more serious note, I haven't used it and haven't seen uray in a while so it is quite likely that the project is out of date

My bad mate, it was quite obvious that you mean 1.1.5. Was just some good natured trolling that is all.

Uray seems to have disappeared, strange it was right after my declining his offer to purchase all of his projects. Hoping he's in good health, and okay.

I talked with him after that and he said he then would be away a couple of weeks in January. Really hopes he come back, he is/was a vital part of BURST.

I cannot find the specs on that CPU, is this a laptop?

When you say your at 2min for reading a block, does that mean it takes you 2min to scan your plot file?

I compared a AMD A4-4000 to my old Intel E5800 and the specs are sorta similar so I'm guessing your processor is similar to mine.

Everyone keeps saying that hard disk space is all that matters, but this is very misleading.  You also need a CPU that can process the data and a decent hard drive connection interface to get the data from the drive and into the CPU.  The hard-drive connection is more important that the CPU.

What is your stagger size on that 5TB plot?  If 8GB ram I am guessing your stagger is not greater than 10000.  What is your hard-drive connection?  if your reading this through USB 2.0 your max on paper read rate will be 60MB/s but take into account overhead and a low plot stagger and your probably looking at ~30MB/s.

I believe that 256MB/TB of plot size is read during each block (dev post on POC vs POCv2), if this is so then at 30MB/s it would take a USB 2.0 ~43 seconds to read the plot.  If your using windows go to the performance monitor --> Disks and watch the read rate for your drive, you can do the same thing in Linux.  This will give you an idea of were you are.

With the CPU I compared your's to I am able to read ~8TB of plots across 5 drives in about 35 seconds.  This speed will increase once I optimize my larger 3TB plots.

Reading a plot that is optimized will utilize your drives sequential read specifications.  Reading a plot that has a low stagger will utilize your drives random read specifications.  I higher stagger will move closer to optimized levels.  I have not created a graph showing this relationship so I do not know the cut-off point but there is a significant difference between the two ends of the scale.

Download a utility like CrystalDiskMark http://crystalmark.info/software/CrystalDiskMark/index-e.html or HDTune and see what your drive is capable of, especially the sequential read indicator, this will be the max you can read with an optimized plot.  Doing this will help pin point the bottle neck, and I am guessing it is not the CPU but a combination of hard drive connection type and low stagger.

* Edit * I just re-read your post, I missed the 4 x 5TB part.  Sorry.  But still basic benchmark testing to find bottle necks still applies.

Good-Luck

Mmmm... I was thinking to try mining with raspberry pi b+ to save electricity, and I don't it is possible now after reading you post above. I think that the reason why I did not see anyone mine burstcoin with raspberry pi yet...

Mmmm... I was thinking to try mining with raspberry pi b+ to save electricity, and I don't it is possible now after reading you post above. I think that the reason why I did not see anyone mine burstcoin with raspberry pi yet...

Why don't you try, likr a proof-of-concept....?  Smiley

It would be quite interesting to know how a raspberry would do, especially as we call BURST "enegy-friendly".

I bet that it's good for about 2.5TB of optimized Plots in roughly 35-45 seconds. A Beagle Bone Black would be interesting to see also, better RAM and CPU but still that poor little USB 2.0 bottleneck.

 I look forward to seeing the results

Yeah, more I look at it, the more it seems like you need a pretty beefy processor when you start tacking on the TBs. I added more memory and it definitely helped (I'll check the auto pagefile thing too), but it seems to have hit a wall.

I'm currently trying out a low end Intel I also have and it's better, but it's still not good enough. I'm at 25TB in 106s (last five finished plotting today).

Are there any plans for a GPU assisted miner? It was said a few pages back it's not needed, but it sorta seems like it is. I can imagine the low end GPUs would be put to good use. Based on the block height chart it seems like you want to get in under 45s, lower the better.

I didn't know you lost your chance at the block if a new block is issued before you finish reading the last, something that probably should be a explained somewhere. It's pretty fundamental and important, but since PoC is new, I had no idea that was a thing.

Also should be listed somewhere that plotting also takes a decently beefy CPU, even while using a GPU plotter. I ran into a wall around 60k nonces a second using the GPU plotter. No matter the number of HDs or GPUs I threw at it, it wouldn't go higher.


Hmmm maybe I'm not fully understanding this. Looking at the read numbers in Resource Monitor, on the Intel setup, it's reading the drives at about 16Mb/s, there is no way it could finish the entire drive in 106s at that speed. So mining doesn't read the whole drive, just parts of it?

I just did some calculations on my bottleneck and my issue is related to the PCIe 1.1 slot that I have my 4 port SATA III card installed in.

PCIe 1.1 has a max transfer rate of 250MB/s  split that between 4 drives and each drive can at most feed teh CPU data at 62.5MB/sec.  If I use itop in Linux to watch my I/O % rate I can see that my I/O goes from 50%-60% maybe a touch more sometimes.  This tells me that my CPU is waiting on data, bu it is pegged at 100% on both cores.... maybe its a miner optimization issue I'm note sure.

So, in my case under ideal conditions I am guessing that my system will peak out at 11.25TB to reach the 45 second marker.

62.5MB/sec max read,  256MB needs to be read per 1TB plot

4 seconds to read 1TB plot.

45sec / 4sec/TB

11.25TB can be scanned in that 45sec  for my crappy old Optiplex 380.

This is just quick 2:30am napkin math but it goes along with the current convo that mining burst is not just about having massive amounts of storage.

Or, maybe it's late and I am just missing something...  When I get to 11.25TB I will find out Smiley

Not sure if that's in response to me Merick, but the weird thing is when I watch the transfer rates, it never gets anywhere near the drive sequential speeds. The drives aren't being maxed out on random seeks or the utilization would be much higher. It seems like it's entirely CPU bottlenecked.

On my Intel rig, I removed all but one drive and got it down to 42s. So 42s for 5TB, 106s for 25TB.

Can someone explain what optimizing does? From what I understand it reorders the plot so it's all sequential reads instead of any seeks? Doesn't the plotter do this when you plot? I only have one plot per drive and it doesn't seem like there are a lot of random seeks happening. Would/how would this help me?

PoC reads 1 4096th of the data each block, or more simply 256MB / TB.

PoC2 will most likely be around 16MB / TB

Will PoC2 be adapted to Burst or are you planning on created a completely new coin?

If crowetic already planned to start the raspberry test, and since I do not have a raspberry on hand yet, then I will wait for your proof-of-concept,  Smiley
