1  Alternate cryptocurrencies / Mining (Altcoins) / Re: [NEW MINING CLASS] MSCoins - Opportunities for CPU and GPU miners on: January 26, 2015, 01:11:25 AM
I can't mine....

I bought some nxt on Bittrex....but the system says I need 1440 confirmations for my coins....Huh

Is this normal ?

That seems rather excessive.  Try http://shapeshift.io, it doesn't get much faster.


Nd I'm getting this error :

Code:
SEVERE Main.main: Exception during program initialization
.IndexOutOfBoundsException: Index: 0, Size: 0
t java.util.ArrayList.rangeCheck(Unknown Source)
t java.util.ArrayList.get(Unknown Source)
t org.ScripterRon.NxtMint.Main.main(Main.java:296)

Does your NxtMint.conf file have two parameters for the gpuDevice line?

For non-Scrypt hashing (i.e. EGOLD) it should be something like:
gpuDevice=0,256

I'm surprised that they completely ignored NXT.  Religious debates aside, that seems pretty biased considering the amount of progress NXT has achieved in one year.  The NXT monetary system is about to go live, which will allow for digital currencies to be be issued and traded on the NXT blockchain, and they can even be minted using proof-of-work or backed by locked NXT.  Following that are plans to implement coin-shuffle on monetary system coins.  IMHO these are going to be very interesting projects to watch in 2015.

Please correct me if I'm wrong, but doesn't PoS require the miners to keep their private keys online on the machine doing block validation?

NXT allows you to lease the balance of your account to another account for forging.  This way you can lease your balance to an empty proxy account that can remain unlocked/online without any risk.  If the account is compromised, you simply issue a new lease transaction for a new account, or move the coins out of the leasing account.  A lease only becomes effective after 1440 blocks to prevent a number of exploits that would otherwise be possible.

Tulip mania!  NXT isn't backed by anything, not even mining cartels!

Lots of misinformation here.  NXT is not a clone of Bitcoin, it was written from scratch using java + javascript and has almost nothing in common with Bitcoin aside from the general concept of using a blockchain.

NXT is a platform for decentralized services that is powered by NXT tokens.  Comparing NXT to Bitcoin as a "currency" doesn't really make any sense.  NXT and Bitcoin can function as complimentary systems (they already do) as NXT was designed from the ground-up to process a variety of transaction types that are not suitable for the Bitcoin blockchain.  I like NXT because I like being involved in projects with promising technology and contributing effort to help them grow - the same reasons I got into Bitcoin.  If a fatal flaw is discovered in the NXT PoS mechanism it will probably fail, but we won't know with any certainty unless we try.  Nobody is forcing anyone else to use NXT and it's certainly not a "scam".

tl;dr If it isn't a mine-able crypto, then it isn't good

If you want to "mine" NXT, you can use a pool like http://hashrate.org.  It mines other alt-coins and automatically sells them to buy NXT that it pays out to miners.   Smiley

You need to use an ampersand for query parameters: "&cors=true"

ex -
Code:
$.getJSON("http://blockchain.info/unspent?active=1CjPR7Z5ZSyWk6WtXvSFgkptmpoi4UM9BC&cors=true", function (data) { alert(JSON.stringify(data)); });

Is DoS expected to be more of a problem with TF than regular forging?   If we can guess who will forge the next block with a high degree of probability, won't an attacker do the same?

If this was already discussed, can someone point me to it?  I'd like to find more detailed information on how TF is planned to be implemented.


edit -
Just noticed this is mentioned in the faq, but not really answered fully.

For sure that will reduce overall cpu usage with 20-30% that is what i observe on my tplinks


That fixed it, thanks.  After disabling LOCK_TRACKING 4.0.1 is now running at a very steady 11% on my system, which is actually a nice improvement over 3.9.   Smiley

EDIT: Also, cpu usage by cgminer seems to have greatly increased. I noticed these things with two machines running Windows 7.

I wanted to post the same observation.  I've been upgrading every few releases and had been on 3.8-3.9 for a long time with a few BFL units.  In 3.9 the CPU usually averages around 15%-16%.  Going to 4.0.1 the CPU usage slowly increases and levels off at ~35%.

Owning NXT is somewhat like owning shares in a virtual public company.  The shares were issued all at once, but they happen to be coins that are traded on crypto markets, which is nice because they are accessible to anyone.  They function as both shares and as the resource used in the network itself.

The forging fees are not attractive right now as an incentive for profit because there is no real activity yet.  To me, forging fees are more of a programmatic "dividend" that is built into the shares.  You are only paid this dividend if you show up to shareholder meetings (run a client with an unlocked account)(run a node).

http://en.wikipedia.org/wiki/Render_unto_Caesar

Quote from: wikipedia
All three synoptic gospels state that hostile questioners tried to trap Jesus into taking an explicit and dangerous stand on whether Jews should or should not pay taxes to the Roman authorities.

The accounts in Matthew 22:15-22 and Mark 12:13-17 say that the questioners were Pharisees and Herodians, while Luke 20:20-26 says only that they were "spies" sent by "teachers of the law and the chief priests".

They anticipated that Jesus would oppose the tax, as their purpose was "to hand him over to the power and authority of the governor".[Luke 20:20] The governor was Pilate, and he was the man responsible for the collecting of taxes in Roman Judea. At first the questioners flattered Jesus by praising his integrity, impartiality, and devotion to truth. Then they asked him whether or not it is right for Jews to pay the taxes demanded by Caesar. In the Gospel of Mark[12:15] the additional, provocative question is asked, "Should we pay or shouldn't we?"

Jesus first called them hypocrites, and then asked one of them to produce a Roman coin that would be suitable for paying Caesar's tax. One of them showed him a Roman coin, and he asked them whose name and inscription were on it. They answered, "Caesar's," and he responded: "Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's".

The questioners were impressed. Matthew 22:22 states that they "marveled" (ἐθαύμασαν) and being satisfied with the answer, they went away.


Basically, Jesus is saying if you exchange your bitcoins into fiat, you have to render some fiat back to the owners in the form of taxes.  Otherwise, if you keep your bitcoins and never sell them, you can use them to buy stuff in heaven after you die.  I'm hoping that by then I'll be able to buy a few stars and maybe a nebula.

I believe this.  I've had at least 6 people call me in the past 2 weeks asking for help setting up Litecoin mining rigs, and all were asking if I knew any sources for AMD cards.  One even offered to buy my year-old 7970 for retail cost.

Also, the Litecoin difficulty has doubled in the last 2 weeks -

17  Bitcoin / Bitcoin Discussion / Re: Depressed that I was not an early adopter on: November 25, 2013, 10:32:13 PM
My regret is that I changed jobs.  In 2009 I was in a dead-end IT job with nothing to do, so I spent my time doing folding / seti / etc. distributed computing projects with as much hardware I could utilize.  Then I made the brilliant decision to get all career-focused and change jobs to a fancy big-name consulting company that demanded all my time with on-call rotations and all-weekend data center upgrades and software installations.  If only I stayed at my dead-end job, I would have surely discovered bitcoin earlier and mined the crap out of it, but noooo I had to go an advance my career.  Stupid rational choices.     Tongue

Either this is the end of profit opportunities in mining...

I think it's been this way for a while, at least for consumers / end users.  Personally, I concluded that as an individual I have no real chance of successfully competing with big money interests that are now in the mining game.  I also think it is very likely that there are many private / secret ASICs and mining clusters being developed behind the scenes, and unfortunately I suspect a subset of ASIC companies are simply announcing delays and mining for themselves with little fear of customer backlash having any impact on profits.

People have been pointing out the fact that ASICs purchased today with BTC will never ROI, but customers just keep buying them.  For someone with a profit motive this is completely irrational, yet it continues.  I'm sure the ASIC companies are happy to sell them hardware as far into the negative ROI window as possible.  As long as the mining hardware can be sold for more than it costs to manufacture, the ASIC companies will generate profits.  They just need to maintain a minimum ratio of difficulty vs. exchange price, which suggests that rising BTC value is necessary for ASIC manufacturers to survive.  Considering that some of the ASIC companies are probably sitting on millions of dollars from private investments and pre-order revenues, they could probably buy up coins on the exchanges an drive the price up themselves if needed... and that is how a proper bubble is created.
