1  Bitcoin / Bitcoin Discussion / Re: Generating Private Keys From Strings Of Words on: July 30, 2015, 02:59:57 AM
More people are starting to make their private keys from strings of words. Wallets like MultiBit HD force you to create your private keys from word strings. If Bitcoin grew substantially larger, surely this would present a problem? I could create a program to randomly shuffle words in 24 word strings (the most words MultiBit allows to create a private keys with), to create private keys and check them for a BTC balance on the block chain. If the keys' address had BTC allocated to it, I could simply withdraw it to my own, untraceable wallet.

Is my understanding of Bitcoin correct in this, and if so, surely this could happen if most of the world's population used Bitcoin?

you have to remember that creating a string of random words by a human can not be completely random. so there is a risk of being hacked.

Here's a passphrase generator you can use -

Just about anything these alt coins think they're bringing to the table can be done with Bitcoin.

Just because it can be done with Bitcoin, doesn't mean it should be, especially if it doesn't fit particularly well.  Bitcoin colored-coins solutions require you to involve a 3rd-party software or sidechain, and different crypto-currencies ARE sidechains, they just use economic "free-market pegs" instead of cryptographic.  

And it has the benefit of the network effect and it's the most secure ledger in the world.

I am looking at Bitcoin solutions. Not alt coins. Every NXT person I have talked to basically wants Bitcoin to fail.

People can be hostile to each other when they have financial interests that they perceive to be threatened.  I certainly want Bitcoin to succeed because it is the value base for other crypto-currencies/DAOs/DACs.  Nxt is an account-based decentralized services platform and you use the tokens (NXT coins) to pay for a variety of transaction types with different fixed fees.  That is nothing like Bitcoin.  Nxt has a lot of digital asset features native in the protocol and you can already do multiple types of deferred & voting based transaction commitments on-blockchain.  If it provides the features you need, at least try it out for free on Nxt testnet.  Nobody is asking you to stop using Bitcoin, and you can always hash your own checkpoints into the Bitcoin blockchain for extra security if you feel guilty.   Wink

i think you might want to look into NXT.... they have everything you need and its quite under the radar at the moment with active development. they just have a problem marketing themselves...

You forgot to mention that the decentralized voting system allows for asset issuers to create polls where only asset holders can vote based on their balance.  i.e.

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, it doesn't get much faster.

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  It mines other alt-coins and automatically sells them to buy NXT that it pays out to miners.   Smiley

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. - "This is possible. If it is a concern for you, you should run your Nxt software through a personal VPN service or Tor. "

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).

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 -

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
