OP does have a point, Satoshi did walk away the moment Gavin accepted the invitation to speak with the CIA. Coincidence?

YES THAT WAS TOTALLY AND COMPLEETLY A COINCEDENCE!!!! HE WUZ PLANNING ON LEAVING WAY BEFORE THAT!

I THINK THE OP IS RIGHT, SO I'M GONNA MOVE THE SOURCE CODE TO SUMPLACE MORE SECURE WHERE THE GOVERNMENT CAN'T SEE IT ANYMORE. AND I WENT AND GOT ME A GOOD HAT TO WEAR WHEN I WRITE CODE SO THEIR SATELITES CANT HEAR ME EITHER.

FOR THE CHILDREN!

Just make sure you avoid those Aluminum Foil Hats..turns out they are actually a conspiracy by the government to better be able to read your mind.

Hi,

I know it's probably somewhere in the 700+ pages but can any tell me an easy way to send Burst to my wallet with the public key that's required for first time deposits?  I just stupidly transferred a fair amount from Poloniex and lost it!  I've looked around but can't seem to find any exchanges that allow you to include the public key for first transfers.

Also, just plotting 6TB at the moment with plenty of room for expansion.  What is the minimum TB suggested at present to give a good chance of finding blocks?

I'd recommend contacting Poloniex and asking them for advice.  No, can't include the public key in the first transfer, have to make your own first transfer.. I guess from an account of someone else who owns Burst?  Which is indeed an issue if new people can't get involved because they can't transfer Burst into their account directly from the exchange to their wallet.. of course I guess the faucet should be once way to get around that?

My guess would be those burst aren't lost, that transaction just isn't valid and will expire or maybe go through once you unlock your wallet.. after all it was sent to your account, shouldn't be able to be claimed by anyone else or just be lost.. idk the answer to that one though.

Regarding finding blocks, please check out this calculator: https://bchain.info/BURST/tools/calculator

I suspect you'll need to join a pool to actually be able to mine any blocks with 6 TB.  See the first post for information there.

http://burstcoin.eu/address/5810532812037266198

some address seem to accumulate a lot of burst right now.

What is this exactly?

somebody stealing money using hacked passphrases?

or is it legit?

hah! probably an exchange!

or a pool?


its poloniex address

whats funny is they are using same passpharase for NXT, NHZ and BURST

That seems like a really bad idea to use the same passphrase.. I know there was talk of a theoretical attack that could cause some problems given this within Nxt..  won't give details publicly but I'm going to contact them about that.

But the point is, I hope that nobody else uses the same passphrase for different coins, especially if they are all forks of the same coin and use the same internal structure for a transaction.. my guess is also that they use the same passphrase for all other coins as well.. which in general seems like a bad idea.. hack one passphrase and you get all of their coins.

Also, how much does Burst have to worry about 'Nothing at Stake'?  Basically you can try to mine on every fork you see?  If someone gets over 50% of the storage, then he can create a separate fork with very little effort that looks correct?  There is one way to sort of get around this but it can't be used to prevent new miners joining the network from joining the wrong fork. So, theoretically, given what is currently implemented.
It is no different than any other algorithm that has 50% value to determine the correct fork. If you own >50% of the Network power (or storage here), you can mine your own fork and publish it once it's ahead of the other fork. Nothing can prevent this in a decentralized system of this kind where the "majority" is right.

The issue is let's say someone started working on a Proof of Work fork.  If they wanted to fake a fork that was 100 blocks long, they would have to remove 50% of the mining power from the main chain to create this fork, this would take 100 blocks to complete however.. by which point in time the network would be 100 blocks into the future, so they'd constantly be playing catch up.

The question is, can you occasionally say fake a fork like this in say 5 minutes with a large enough percentage of network resources that the network accepts and uses to overwrite the 10 confirmations of a blockchain which cheats the system and overrides that calculation?
You are correct, a fake fork could be constructed in less time catching up to the current time starting from a block farther back than mining the real one took Considering the reading time for many user's plot files, you could probably construct the fake one in about 1.5 minutes/block. In order to achieve at least the same cumulative difficulty without running into the future(which would cause the chain to get rejected), the fake chain would still have to have a higher hashrate than the real one. In the case of semi-honest miners on both chains, catching up would probably be slower, as miners would be reading different data for each chain, so 3 minutes/block for creating a fake chain would be more likely, making catchup still faster, but not by as much.

Thanks for mentioning this, I'll certainly be keeping it in mind.

Yeah, I don't see if as a huge negative.. like you said, still need to have more than half of the hashrate, but if someone could keep it, for a relatively short time, they could cause problems, starting from the past blocks.  Exactly, just something to keep in mind.

How large are plots?  I thought the idea was they were hundreds of GB large.. but first post seems to indicate 262144 bytes?  I was thinking plots were something like 200 GB.. large plots would be good for ASIC resistance.. and could probably be used to lure over some litecoiners who recently lose that advantage.  I would target devs or various coins and people who have made a difference first instead of just announcing it to the community as a whole though.

Plot is 256kb. Every block a random portion of plot (1/4096) is used for mining (I'm simplifying things a bit).
The more plots you have the more chances of finding the best deadline. Generating plots 'on the fly' is very CPU-intensive, so the coin is ASIC-resistant.


Interesting... thanks.

So I'm supposed to spend months of my life working for free?  Don't get me wrong I like crypto but I want to make some money.

Linux is open source.
Bitcoin is open source.
LibreOffice is a multiplatform open-source office suite.

I'm sure I can give you hundreds more examples. Each of those projects are "free to download and use" but the developers have happy lives and are being compensated somehow.

In the beginning, open source software looked like a saintly gift. Programmers would work hard, then give away the fruits of their labor to anyone who wanted it. Everyone would benefit from this act of pure charity.

Over time, however, companies realized they could make money and give away the software at the same time. They could do well by doing good. This wasn't a shock to some of the original open source advocates -- it was how some intended it to be. Richard Stallman, for one, always said that "free speech" was more important to him than "free beer." He embraced the idea that companies could charge anything they like -- as long as the user could fiddle with the code and distribute the result.

There is a common misconception that there is no money in open source software. It is true that open source code is free to download. But when it comes to making money you should think of this as an opportunity rather than a limitation.

    Businesses who make money in open source software include:

    MySQL (now owned by Oracle): Popular relational database.
    Red Hat: Major distributor of Linux for server and desktop use.
    WordPress: Widely used blogging platform.
    SugarCRM: Business customer relations management.
    Magento: E-commerce shopping platform.
    Zimbra: E-mail and messaging server.


If your idea is truly worth something, even if you give it away for free, you will surely get compensated somehow. I don't know how.

If it's not, then no one will pay for it anyway.

Appreciate it, the problem is that if I'm implementing this nto someone else's coin, they are making money and I'm not.. because I didn't get in on the ground floor. the only way that I can see to make real money with it seems to be to start my own coin.. But there are already too many as it is, in my opinion.

But maybe the name recognition alone is enough.

Thank for treating me with respect.. I was on the fence about whether or not to patent or pursue anything like that. NXT community was encouraging me not to actually. But I was thinking about it.. and you know the biggest reason I want to pursue it? This thread, being called a troll, being told I don't know anything, etc. But if my initial reception had been closer to Dabs, might've freely shared the idea.. honestly, I'd prefer to just talk openly about it and bounce it around with others.. But there is something to be said for trying to make some money of it.. and for not wanting to help out Bitcoin if type this is the reception I get.

We should just ignore the guy, we're feeding the troll. He'd be building something if he had anything worthwhile or the money to waste on patents.

It isn't exactly the kind of thing you do overnight.. But again, thank you for providing me more incentive to try to jump through the hoops and hassle and spend the money to try to patent.

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?

Though again.. it comes down to how you were storing your passwords, since the wallet shouldn't be storing passwords.. so even if you find the wallet it doesn't lead to passwords, unless you were holding passwords in a file in the same folder?  We had someone lose 6 million Nxt that way..

Most miners require storing a passhprase in simple .txt file in the same folder as the miner when solo mining, so it's pretty easy to steal. Sad



Sad  This coin has a lot of potential.. but I guess still has a few kinks to work out, should be a better way of doing that... surely Bitcoin has a better way of doing that right?  I guess they use the wallet.dat file.. which is an improvement.

I'd prefer it if Nxt required more secure passwords than they currently do.. seems extremely unlikely it'll get hacked but still 10 random words.. I'd make it more and/or include random letters and symbols.  But I guess it's probably good enough for now.

...I still implore that if anyone has the skills to trace this kind of thing, please help me, I'll be happy to split what I used to hold with you if you can recover it.

I unfortunately just lost 30k burst to this same address. I dont no what the hell happened. I am pissed. Let me know if anyone finds a solution that was essentially all my coin.

How did you choose your passwords?  The prime suspect in these kinds of losses is always a weak password.  It's a flaw of the NXT approach which burst has inherited.

Nxt is more secure now.. when Nxt first launched you had to pick your own passwords.. when people pick single dictionary word passwords.. that's a problem.  It's a reason the wallet now forces you to choose a new password the way it does.

I reviewed the diff with NXT in detail at 1.1.3 or so.  Found nothing nefarious.  Actually, a lot of it is undoing the NXT premine, which is kind of anti-nefarious. Smiley

Good that you reviewed the diff Smiley

NXT wasn't premined, it was IPOed!  BCNext should have waited longer and allowed more people to get in but I actually think it's a very fair way to start a proof of stake currency.

332  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.5 on: November 05, 2014, 02:01:38 AM

Could ppl who lost the coins write which Burst-related software they were using recently, on which OS and was the software compiled from source code or binaries.
Let's try to find which one had the trojan. I've checked the diff of the latest wallet when upgrading, seen no suspicious changes.

And could've been a non-burst wallet or software.  Odds are it'd be within the crypto community given that most don't know about Burst.. or maybe they were even targeting Nxt and if a hacker can find the Nxt wallet, he can find probably find Burst, given the similarity.

Though again.. it comes down to how you were storing your passwords, since the wallet shouldn't be storing passwords.. so even if you find the wallet it doesn't lead to passwords, unless you were holding passwords in a file in the same folder?  We had someone lose 6 million Nxt that way..

How do you guys store your passwords?  Nothing you could have done with it or software recently downloaded?

And seriously, how many people reviewed the source code?  Only burstcoin?

If it's an issue with the algorithm or something this could be bad.. reminds me of the early Nxt hack where some guy discovered he could empty the wallet of anyone who'd ever sent him money.  LUCKILY, he was a great guy and reported it an it was fixed up but that's my biggest worry when investing into a new coin.. bugs or potential hacks.
334  Bitcoin / Development & Technical Discussion / Re: Faster bitcoin transaction times on: November 05, 2014, 01:32:14 AM
Anyway, clearly you and I have moral compasses and looks like we'll just have to agree to disagree on the patent issue.  I'm not intending to use it to block Bitcoin from anything or chrage extremely unreasonable rates or anything like that.

With Bitcoin, anything above zero is extremely unreasonable. It's supposed to be open source.

So I'm supposed to spend months of my life working for free?  Don't get me wrong I like crypto but I want to make some money.  I was pretty excited about sharing the idea..tell you what.

Anyone willing to pay me not to patent the idea? lol  I'll share the idea with you first given a non-disclosure agreement.
335  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.5 on: November 05, 2014, 01:24:24 AM
So, i don't know if anyone has had any security issues after updating, but I updated to burst 1.1.5 last night, and woke up this morning to all my burst missing from my wallet. I had about 9.8k that I've managed to mine with a measly 2TB, and after tracking it on the blockchain I've come up with this address:
http://burst.cryptoport.io/acc/BURST-FRNC-8G44-FNQP-AEQFS

who then forwarded my almost 10k, as well a substantial amount of burst (about 470k) to this address:
http://burst.cryptoport.io/acc/BURST-68JV-2EAW-WDRB-FKZ4Y

Where it is now sitting. Any attempts by me to track down that address (and an IP that it is currently running on) have been futile thus far, and I know that in the crypto game seldom will i recover what has been stolen, but I still implore that if anyone has the skills to trace this kind of thing, please help me, I'll be happy to split what I used to hold with you if you can recover it.

Please and thank you in advance.

Sad

Did you download any software recently?  Particularly crypto related?  Maybe input your password into a mining pool?  A password that long should be quite secure against hacking without someone reading it off of your machine or you giving it to someone.  Just wondering how the thief could have gotten it.  Either that or maybe there is a hack in the wallet.. anyone check anything into source code that wasn't well tested?
336  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.5 on: November 04, 2014, 09:03:35 PM
This is HUGE  Shocked   Price should skyrocket  Smiley

I would hope so but if it does then it should happen a few days after.   Grin
Keep in mind this is a Nxt clone, Nxt has tons of supporters and just like Burst can take from Nxt, Nxt can take from Burst... then Nxt benefits more than Burst does.

Also, here's my issue with this big update to add subscriptions, why would I agree to a subscription when the price could fluctuate by a factor of 3 or more between payouts?  I wouldn't even use a Bitcoin subscription, let alone any alt coin's subscription feature.. not until the price very much stabilizes.
337  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.4 on: November 03, 2014, 04:45:57 AM
I don't understand why does 4096 optimize it for hdd?

For each nonce/accountId combination a 256 kb chunk of data is pre-generated during the plotting process.
You can specify any ranges of nonces, just make sure they don't overlap. Otherwise same work will be done twice.
Plot files serve as a giant lookup table for further computation. Plot files can be stored on ANY device, hdds, sdds etc. Doesn't matter which device, only the available space matters.

For each block only 64 bytes (scoop) from each 256 kb chunk are really used. These 64 bytes are selected depending on block id (which is not known beforehand).

It's not possible to generate these 64 bytes on the fly. Only the entire 256 kb block can be generated, but only 64 bytes will be used. This makes the algo terribly inefficient for CPU/GPU mining.

As a result of final computation (during mining) a deadline is produced. A person with the shortest deadline will announce the next block once this deadline expires.
I hope this helped to clear things up a bit. Smiley

Also, have any coders looked through this coded and approved or has only one guy written it?  People analyzed the algorithm looking for flaws?

I did, haven't found any flaws. The algorithm looks very solid, couldn't find a way to abuse it.
I'm not a cryptography expert though.


Thank you, now how do you verify that the correct person generated the block?

And what if multiple people have their plots tell them that they can generate a block at the same time?
338  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.4 on: November 03, 2014, 02:59:28 AM
It's an interesting algorithm, couple thing I'm trying to figure out if someone could help me out:

How reliably can you be sure when it'll be your turn to mine?  I guess multiple people could potentially mine this block but it's just the person with the highest number wins or something like that?

Also, I mostly understand how you create the plots from reading the introduction.. how do you then verify that you pulled out the correct one and that you have rights to author the block to the rest of the network in a way that they can verify it.. seems to me like the rest of the network would almost have to do a lot of heavy duty hashing to copy the way you generated that number in the first place and arrive at the same number in order to verify it.  Must be some way around that?

You can mine with ur gpu etc. But due to the whole scoop thing, if you mine with cpu/gpu it is highly inefficient. 1 in 4096 blocks a scoop becomes valid, were it 1 in 16000 then cppu's would be advantaged, were it 1 in 512 ssd's would be advantaged. You get the picture? BTW, i'm on irc, so come Smiley #burst-coin

Check out the op, diagram there, and also, blocks are 4 minutes Smiley

I don't understand why does 4096 optimize it for hdd?  Simply because there is so much data to hold on to per plot? Why not SDDs?

Given this:
Plots are generated by taking a public address and a nonce, then hashing it, pre-appending the resulting hash, repeating the hash-pre-append cycle many times, and then hashing the whole thing and xor'ing the last hash with the whole thing.

First of all, how does someone win the right to author their first block?

After authoring their first block, they then take the last block they authored, and use the next scoop from their plot, in order to prove they have the right to author their next block? Then when they get to the end repeat from the beginning?  Is there a concept of difficulty?

I understand how the plots are overlapped but I don't understand how he can claim sequential reads.  All plots don't stay in sync with each other right?  You could be further along in one plot than the other right?

Also, have any coders looked through this coded and approved or has only one guy written it?  People analyzed the algorithm looking for flaws?
339  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][BURST] Burst | Efficient HDD Mining | New version 1.1.4 on: November 02, 2014, 10:41:14 PM
the bluray storage for now is only useful for really offline stored data. this may change as soon as blueray disks become much cheaper than hdds. the main effort for facebook to be able to invest into this technology is that they have to keep really much data for legal reasons which is randomly accessed once if ever. i looked into alternative storage methods for burst almost three month back. for each block only 1/4096 is read from your plots but which part this is depends on the previous block. if you think of putting 100tb into some sort of cold storage you have to have almost instant access to "random" 25 gb within the blocktime.
for the case of blueray this means you require to read half of a disk within 4 minutes or even faster. the speed is limited to a maximum of 36 mb/s (8x) on the outer sectors and physically limited due to the facts that the medium rotates.
current holographic storage approaches look promising but there is no company releasing any products to public. eg. inphase announced to release a 300gb storage media for 180$ in 2007 and to release them in 2009. this means if the technology works it would be the perfect base to store your plots.
however, i just want to point out that hdds may not stay the only way to store your plotfiles in near future.

Ok, so hdd are still currently the best techonology.. if you can turn it off or on for extended periods of time, maybe energy efficiency isn't a big deal.

oh pluuuze, muh superior pos sales pitch

You do realize there were pure-PoS schemes before NXT, right?

But since we're flaming here and all, here goes equally vague statement:

In Pure-PoS schemes, consensus can be deadlocked to dangerously small number of holders.
Human nature is not always rational, some safeguards are necessary (such as PoW, or
something else of that nature).

I wont explain why is that, just head over to Peercoin thread for detailed criticism of PoS and why it needs a PoW backup.


The future of burst is not in HDD's, it'll be in robots and blurays, and that'll be replaced.

If you want to make the calculation, base it off gpu's, cause burst has no asic's yet, and when it does they won't be BAD. They will be new, better storage devices.

http://www.wired.com/2014/02/facebook-robots/

Also, please note that, if you want to mine effeciently, you could do only like 8 scoops/drive, which means that the drive is off for a majority of the time.

8 scoops would mean that drive only comes on once every 512 blocks.

NOTE: storage is expensive, so perhaps the robots will use waaayyy less power, but the home user with an on computer would always have the upper hand, as their computer is on in any case, and the hdd doesn't use extra power.

Also, https://burstforum.com/index.php?threads/what-about-optical-media.261/ Smiley

Yes, but Nxt has plans for a system that would enable protection against even 90% of the forging stake attacking the network.  Actually it's a fairly simple and ingenious tweak to the algorithm.. if you don't receive a block within 15 seconds (maybe to be bumped to a minute), then you don't count it's "Base Target" toward the total cumulative score of the chain when choosing the longest chain to follow.

It is true that blockchain trimming would be much trickier.. and probably involves using something along the lines of service providers, where others host the chain for you and you check multiple chains, or every few months or every year or however often you create a 'new genesis block' that includes all the current balances.  But you needing to use data internal to the blockchain means 'lite' clients are probably out of the question, unless you trust others to provide the blockchain up to this point.  Which may be doable, so, they are using economic clustering in order to provide extra protection against attack on the network.  So you can have many big businesses all choose the 'correct' chain they are running on and provide.


But back on topic:

I wasn't trying to insult Burst.. I was thinking about sticking a few BTC into it and I'm just researching my potential investment.

A couple problems with my calculations:
Turns out my calculation was one using an 'energy efficient' hard drive.. which is less reliable.  So you'd pretty much want to use one that works at 10W instead under full load.

Also, I started thinking that maybe you could frequently idle your hard drive but it is believed that's much worse on it's life than continually running it.. so you would want to keep it under full load.. at which point you actually use more energy than the Bitcoin network.  Which is a shame.. I really thought this was a cool idea and might address that problem and that it was basically the whole point of choosing proof of storage over proof of work.  I will admit that reusablity and the fact that this can be made into something that allows everyday people to use that piece of hard drive space that they don't use and get paid some tiny amount for it, is appealing.

It's possible that new and upcoming hard drives will be more efficient and fix this issue but the biggest problem is that their price is going down so much faster than their energy consumption, so this problem will likely become even worse.  And not only that but I suspect that Bitcoin miners will also continue to get more efficient with time.

What are other advantages to using Proof of Capacity over Proof of Work besides energy? 

Ones I see are:
It's pretty ASIC resistant, because if you can make better harddrives.. then you can use them in PCs everywhere.
Related to which, you don't need fancy hardware and if you get a hard drive specifically for this issue.
Hard drives are reusable for other purposes, if they don't die first.

I really do like this coin, just trying to look at it from all angles.


EDIT: WAIT.. I might see what you are saying.. I misunderstood the blu-ray thing since that specific article doesn't mention energy efficiency, but after looking around other places.. I see that those are significantly more energy efficient.  Turning the hardrive on and off is indeed not good for it but only every 512 or so blocks wouldn't be bad.. How long are blocks?
