Can someone give an update to the instant transactions feature.  That is the defining feature between NXT and every other coin.

As far as I understand Instant Transactions depend on Transparent Forging, which is promised to be fully implemented before the date of the first anniversary of NXT at the end of November.

Here is the development roadmap (Instant Transactions are still in design phase):

Excessive spending leads to default. But people still vote for politicians that promise things that they can't afford.

Perfect definition of what US is doing, but hey, they print the currency they owe everyone debt in, so that doesn't count Smiley

So, after 4 years, they still have not managed to solve the debt problems?

The only way to solve it is default on debt obligations or printing money/taxing (bail-outs/bail-ins) citizens. Or a combination of all those means. In any case it will be a nasty looking affair.

The debt is denominated in other currency, they ca't print money out of their way.

Sure they can. Of course, not that bank or Portugal, but the European central bank, they have all legislation in place for that and they are doing it. They also have legislation for bail-ins in place. Doesn't matter what debt is denominated in, they can devalue euro to buy dollars if the debt is in dollars.

That only proves Vericoin is a fail.
There has been numerous successful attacks on smaller PoW coins, but Bitcoin is still here (although it can be argued for how long).
But the thread is about something else, about hypocrisy.

Digital currency is digital. It doesn't need ENERGY to survive to justify itself. POS can be duplicated. Just like Bitcoin can be duplicated and XMR can be duplicated.

Not exactly. He's right in a way. Energy is scarce. You can't duplicate Bitcoin or Monero a million times with their high hash rates because the energy usage would be prohibitive. You can create a little million shitcoins with virtualy no hash rate, or which are constantly stealing hash rate from each other as miner jump to the latest scam, but those are not duplicates of the BTC or XMR network.

POS coins can be duplicated quite literally without physical limit. That is a major difference.

I don't totally agree this means they can never have value though.


If that logic is applied, would you say that Fantomcoin should be more valuable than Monero, because it can be merge-mined with it and a few others, meaning it can easily have more energy spent on mining it (larger total hashrate) than any other single CN coin? So why does it not happen? Is it because of energy spent or because there are not enough users/marketing/development efforts of Fantomcoin after all? What comes first - users see value in a coin or miners come to mine it? I would say miners follow the price, not vice versa, which proves my point that it's useful properties of a coin that matter, not how much energy is spent on it.

@kbm, see my post on why energy spent doesn't back a coin, because there is no guarantee that you can exchange a PoW coin for kWhs of spent energy. Backing a currency with some tangible things in the past centuries meant you can redeem bank notes for gold or silver. You can't do that with a crypto, so it's pointless to talk about some sort of backing with energy.

The value of a coin is not found in how much hardware it takes to 'extract' it, but in useful features it offers to users.

You may not call PoS a coin, but a share or a token, does it really matter if it's used to transfer value and pay for goods and services just like PoW coins are used? The end users could care less about those definitions, to them it's all vehicles that have properties of money and can act as money, which is all that matters.

You can duplicate source code of a PoS coin, but you can't duplicate infrastructure and developers. And by the time you can, the network effect has already set in and competitors can't catch up, provided that development of the first PoS coin hasn't stopped, both software and infrastructure development.

It is also important to consider user base and ongoing distribution which can't happen overnight for any PoS clone.

Obvious is obvious.

For the sake of the debate stating the obvious shouldn't be done so bluntly Smiley
1248  Alternate cryptocurrencies / Altcoin Discussion / Re: To all who claim 'fair distribution' is not possible in a PoS, only in PoW... on: July 31, 2014, 09:26:28 AM
You are saying that the fair way to distribute a new currency is to give it to a specialised group of people that have special skills and expensive computers rather than just distribute is over as many people as possible?

No, I do not.

There is no fair way is my take on it, and even if you distributed all coins to all 7 billion people on Earth equally, a few years later, most coins would end up in the hands of a few of them. Hence, the 'fairness' aspect is of secondary importance. More important aspects are technical aspects and useful purposes of the coin.
1249  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 09:23:44 AM
After going from fiat to stocks to gold to silver to bitcoin to monero, in search for increased security, it would be funny to go back to fiat again, wouldn't it?

Fiat is a currency proclaimed and enforced by a government as money, literal translation of fiat - 'by decree'. I am not sure what you refer to when you say "going back to fiat".
1250  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 09:20:12 AM
Which, again, is a very wrong statement. Buyers, regardless of method, care very much if their coin is going to be around in 12 months, and for PoS, this is unproven.

smooth: +1

I agree that many investors want to see the PoS crypto to stay around longer without breaking to invest. My statement was assuming that. And because there is no rush in the mainstream to invest in crypto currencies, although there has been some progress in the past 12 months, there is still plenty of time to prove to new users that certain PoS implementations are at least as secure as PoW.
1251  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 09:10:37 AM
How can you be so sure about that?

Reality check! It's only profitable to mine if you have access to free electricity (most people don't), or you're a botnet operator (most people aren't) or invested and keep investing hundreds of thousands of $$$ into Bitcoin ASICs (most people don't, they invest thousands $$$ at best which is not enough to make mining profitable).

The more questionable part of the statement was the assertion that buyers don't care about PoW or PoS. They might not care about the inner workings, but they damn well care in so far as it affects the security (incl perceived security) and value (incl perceived value) of their investment. To some extent this may be arbitrary or unfair (or perhaps a better word is undeserved). Perhaps PoS just has a bad reputation for whatever reason not based in actual security (and being associated hundreds of PoS scam coins might well be part of the reason), which affects its perceived value and therefore is value. In that case it is still a bad investment (unless you want to make a bet on this changing in the future).

The thing is different PoS implementions are different. NXT's PoS implementation is not the same as Peercoin's PoS implementation, which in PoW world would be equivalent to hashrate of the network, hence security of different PoS coins is also different, same as security of Bitcoin's network is different from security of Dogecoin's network. There has been no serious and full assessments of NXT PoS implementation by PoW experts yet. The most they did in regards to PoS was look at Peercoin's PoS and claim that any PoS is insecure, which is irrelevant and not true, because it doesn't say anything about NXT's particular implementation.

Myriadcoin is the only coin so far that I know of that really tries to do a fair distribution of coins.

Well, it goes to prove my point that most people don't care about fair distribution, because we don't see a lot of Myriadcoin supporters.

They only cry 'unfair' to PoS when it suits their agenda (they already have a good stake in hardware or their favorite flavor of PoW coins (Bitcoin most often) they mine).

If they truely cared about fair distribution, they'd run to mine and hodl Myriadcoin, but they don't. Nobody gives a fly about fair distribution (except a few Myriadcoin developers), anyone with a slightest touch of reality can observe that. Hence, I and anyone with senses can make a conclusion it's just hypocritic talk on their part. But we won't hear from them in this thread probably, they know they will lose in a debate.
1253  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 08:03:30 AM
But that is just ridiculous.

Let's assume I have a large investment in PoW coins. Of course I spend adequate resources to review the possible competition from PoS, to assess if the technology is valid and if I should - for my own sake - diversify or change the train. By doing this quicker than the others, I salvage the full value of the previous coin AND participate in the appreciation of the future coin. (This is what I am doing with Monero.)

I feel that PoS is grasping straws because almost all big names have evaluated it and rejected it, and there is little hope for increase in value in these conditions...

Then you might be one of the few that don't have emotional attachment and other kind of attachment to their investments, if you really do what you just said you do.

Which big names evaluated and rejected it, if some of them even say they can't properly assess it without a whitepaper? Smiley (Keep in mind that different PoS implementations are... , different. Peercoin PoS is not the same as NXT PoS implementation and what some experts say about Peercoin PoS can't be applied to NXT PoS).
1254  Alternate cryptocurrencies / Altcoin Discussion / To all who claim 'fair distribution' is not possible in a PoS, only in PoW... on: July 31, 2014, 07:09:46 AM
...you are hypocrites, because none of you stands in defense of Myriadcoin, which allows for a truely fair distribution among all PoW coins.

You only talk about fair distribution, because you have invested in ASICs that allow you to mine Bitcoins or you have mined Bitcoins from the early start and have shitloads of them now (called 'vested interest'). 99.999% of people who are not miners don't give a rat's ass about distribution, as long as the crypto does what they need it to and they have to buy the crypto, PoW or PoS with fiat anyways.

There you go, slap on your face Wink

$400-450 is possible, $220 probably not, if only in a short-lived spike on one exchange like the one that happened in March on btc-e.

That post exactly makes my point:

Quote
I eagerly await a full whitepaper description and open source code of your complete protocol so both myself and more formal academics can properly whack at the specifics.

As I said, "show your work." Write down all the assumptions and every step in the derivation of your security results, along with the implementation, and then let other people look at it.

In any case, this is pretty much far off topic for Monero. Let's continue this discussion elsewhere.

There is a whitepaper, but probably not a detailed one for someone's tastes (someone is still working on it as NXT evolves). Other than that it's the source code only. That's where the true mathematical proof is. It can be argued that "showing your work" is best achieved by running a crypto without it being successfully attacked, but there has been reviews also, although perhaps not by PoW experts for the reasons I stated above.

Ok, let's go back to Monero.
1258  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 05:38:04 AM
As a Proof-of-Stake systems developer for the past year and a half, my personal opinion is that all of the PoS systems are different levels of insecure (I have doubts that even the one I'm designing is secure, but I'd like to see what happens).

You could outline flaws in NXT as you see them, if you are up to it, because, as you understand, without proof any claims are just that, claims. Different levels of insecure is interesting, a particular implementation of PoS only needs to be more secure than the strongest PoW implementation and network to have the argument of insecurity burried for a long time. It could still allow some theoretical attacks, but theory and practise are far from each other.

More recent comments. https://blog.ethereum.org/2014/07/05/stake/

If anything Vitalik is biased in favor of PoS. He really wants to find a way to make it sound, and I think their plan may include a combination PoW/PoS for Ethereum, but they haven't quite solved that yet, much less pure PoS.


Vitalik actually signed up an nxtforum.org after that blog article and asked some questions and got a somewhat satisfying reply. Of course NXT is still developing, but there is no obvious attack that could be staged against it at this point, at least no easier practically than attack against Bitcoin, perhaps two orders of magnitude more expensive (buying coins vs buying hardware).
1260  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 31, 2014, 05:20:49 AM
Is there such a thing as unbiased experts in crypto currencies?
Probably not, everyone has biases.

But math is math, and if you show actual mathematical proofs, the experts will fall in line (and even build on top of your work).

For example, much of the cryptonote cryptography gets good reviews from people who are clearly biased toward bitcoin (gmaxwell being one well known example). They also come up with some very valid criticisms and suggestions for improvement (which we considering).

There could be two reasons why Bitcoin biased experts actually attempt to review cryptonote.
Because: a) they don't feel that their Bitcoin investments are threatened by CN cryptos; b) because cryptonote is also PoW, which falls in line with Bitcoin and reinforces faith in PoW scheme, both for themselves and newbies who only start looking into cryptos.

PoS is a totally different animal, and getting someone who has been a strong believer in PoW to review PoS objectively is a problem Smiley because in case they find out PoS is safe and better, they can't back out of this, because then math would prove it, which means the status quo of their PoW investments would be shaken. So for now the approach is to stick the head into the sand hoping PoS would just go away by itself Smiley
