I've been using my old MacBook as a full node for a couple years without a hitch. Just upgraded Bitcoin-Qt to 0.10.0 and now it crashes upon startup. Any thoughts?

"Incorrect or no genesis block found. Wrong datadir for network?"
by

So I experienced a problem that others were also having where av software (avast) thinks some files (specifically, in my case, blk00129.dat, 1774506.log, 1774710.sst, 177415.sst, and 1774760.sst) within Bitcoin Core are viruses. Avast automatically quarantines the files. After reading about the problem, I tried to restore the files, thinking that would get me back up and running. Instead, I get the error "Incorrect or no genesis block found. Wrong datadir for network?" The files which were quarantined, and supposedly restored, are not in Library/Application Support/Bitcoin (Mac OS X). Actually, the .dat file is there but the chainstate files and log file are now different. Incidentally, blk00000.dat is still there, which I assume is the genesis block the error is referencing. Any help? Did some googling and found people having this error with altcoins but couldn't find pertinent solution. Thanks.

Re: Whats the point of PGP signatures in BitcoinTalk messagess?

on 21/02/2014, 08:30:25 UTC
I wonder if the "new forum software" could include a feature that makes signing/veryfying with pgp(or bitcoin addresses) easy

How could it be made easier? I've thought about it in the past but I couldn't think of any major improvements that wouldn't also hurt security.

Resurrecting this thread because I noticed nobody responded to the forum admin posting that he's interested in incorporating a pgp feature set into the forum software . . .I'd love it too but don't myself have any suggestions.  Anybody else??

1. IT'S A DECENTRALIZED CURRENCY

Does this even require any explaining? Do you honestly think that the current financial system that controls Trillions of dollars in the current global economy, is going to give up their power to some guy Guatemala because he ran he's 1990's computer the first year of Bitcoin.

Let's all open up our history books and see when the 99% won against the 1%? Almost never, and even when they did “win” it was basically the 1% handing off power to another form, and still running it behind the scenes just to appease the people.

Even if they allowed Bitcoin to become successful, they will regulate it so heavily, that it will pretty  much lose any “benefits” that it had, (Europe is preparing to tax and regulate Bitcoin) and pretty much becomes centralized and just like anything else.

The current system will stay in power with centralized control, hence why they will create their own digital fiat currencies replacing their paper, to even gain more control.

Let's be optimistic.  Let's say a distributed ledger like Bitcoin allows for a true global democracy and a way to usurp our current corruption!  Underdog story to end all underdog stories.

2. CENTRALIZED MAIN DEVELOPMENT

Basically the “official” releases come from the Bitcoin Foundation. The development is pretty much centralized. Even if people fix everything wrong with Bitcoin, the foundation makes the final decision on what to include in it's next version on it's own priorities. This is basically all run by “Gavin” who caused Satoshi to disappear after he decided to meet with the CIA. The same guy who has not addressed any of the issues going to be discussed below for the whole time he has been in control. Whether by accident or on purpose is not the point. The point is the main trusted Bitcoin client is controlled by one entity, and everything they say, do, or don't do goes.

Let's not get all paranoid.  Open source fork and pull...of course somebody's gotta do some work on it.  Gavin et al are astute and have Bitcoin's best interest at heart.

3. FLAWED ARCHITECTURE

Size

11 GB today.
100 GB 1.5 years from now
1 TB 3 years from now
10 TB 4.5 years from now
100 TB 6 years from now
1 PB 7.5 years from now
10 PB 9 years from now
100 PB 10.5 years from now

You think average people will store a 100TB worth of data? No. The solution cut the blockchain into pieces and store the whole blockchain only on specialized nodes, kind of defeats the purpose of decentralized than doesn’t it?

Your breakdown is flawed.  And also the "average" person doesn't run a full node.  If any pruning has to take place, it's not going to centralize Bitcoin.


Double Spends

Double spends are already occurring, and have occurred since over 1.5 years ago, and it will only get worst as time goes on, and bigger merchants and higher ticket items come online the then you will really see the “bad pool operators” start to take advantage of this.

Nobody is going to double spend on a cup of coffee, nobody is going to commit fraud for small amounts, well at least not in person, but they will for big ticket items.

This doesn't have potential to be an endemic problem.

Slow Speed

Waiting for a transaction to fully confirm, is not feasible for day to day transactions. Yes let's hear the Credit Cards take 180 day confirms. One no they don't they confirm instantly, the money is just on hold for 90-180 days if the merchant sells a crappy product and refuses to honor warranty or remedy the issue. If it's fraud, say someone uses someone else card to buy something, the money does not come out of the merchants account, the credit card company takes the hit. Secondly, most important the buyer pays and gets his goods immediately, unlike Bitcoin where they have to wait for a few confirmations to be sure.

Built-in escrow.  Insurance services.


Un-Scalable

Bitcoin can barley handle a few hundred thousand transactions a day, what happens if the transactions grow to 10 Million, 50 Million, 100 Million which are all still relativity small transaction numbers compared to the 6 Billion people in the world. It simply can't handle it.

What exactly do you mean?  Are you talking about the blocksize?

51% Attacks

51% attacks which don't have to be 51% of the network, as they can do it with far less hashpower, such as ghash.io 29% the two biggest pools combined make up over 51% of the network and can literally destroy Bitcoin at any second. It doesn't even need to be the pool operators, it can be hackers who take over the pools.

Why would they want to destroy Bitcoin?

Unstable Exchange Rate

It can never be used as a sole currency to replace all other fiat currencies. Why? Because it's price is unstable. It must always rely on another fiat currency to have any sort of monetary use, no merchant is going to transact when the price of the currency fluctuates 50-200% a day. The only way to stop this is to have actual control of the currency and adjust creation.

Come one man, really?  It will eventually stabilize and you won't need to think about it in terms of Dollars

4. NO BENEFIT OVER FIAT

With everything mentioned above it shows that Bitcoin has no real advantage over fiat for 99% of the people in the world. You can't pay your bills or general living expenses in it, can't buy much with it. It's slow, not consumer friendly, as once a payment is sent there is no charge back method. Guess what 90% of the world are consumers not merchants. If Bitcoin doesn't appeal to the regular consumer who buys goods from merchants it will never succeed. Even if it succeeds it's doomed by it's very architecture which can't handle the success.

The only use it has, is sending small internationally pretty quickly, which then again gets converted to fiat for people to actually use. What market is there for small international payments 5-10% of the world?

No entity would trust high sums of money to be transferred with Bitcoin with all of it's flaws. Want to know how right I am and how wrong you are? Bitcoin has about 3 million users in a 5 year period. Facebook in that same time had what? 600M-1 Billion users.

Not to mention by the time, I have opened 10 accounts just to buy and convert Bitcoin, I could have swiped my credit/debit card 1000 times.

These arguments are so near-sighted.   Can you just give it a few years?

5. CONCLUSION

Even if Bitcoin or another crypto currency fixes all of these issues, they are still doomed to fail because of reason #1. Let's please remember that Bitcoin is Constitutionally-protected.  It's a commodity exchange mechanism based on a decentralized proof of work public ledger.  We have as much right as anyone to make private market.  What if people didn't preclude even more egregious violations of our civil rights?

With zero advantages and quite a few disadvantages over fiat, centralized incompetent development, and inhert flaws Bitcoin is doomed. So next time you get excited about Bitcoin growing, and can't wait for it's mass adaption, just know it's own growth is another nail in it's coffin. Bitcoin is digging it's own grave.


Before all the geniuses on this forum come and give your wonderful flawed opinions, and say how wonderful it is, and it's going places, and I am wrong, and Gavin will fix everything, and Bitcoin will take over the world as a currency and payment system. Please refer below to get a reality check:

Bitcoin users in 5 years: 3 Million

Armory's not windows only - works in Linux and I even recently tried an OSX version, but it's not "there" yet.  I does fetch the blockchain using bitcoind, so if you've already done that, you're good.  I really like multibit - even in the Linux machine I use for bitcoin it works great.

Truecrypt will help if your computer gets stolen, but if you get hacked while it's running (much more likely) then they'll be able to keylog you and get your bitcoins.

Consider getting VMWare Fusion and making a rather hardcore Linux VM to keep your coins in.  It provides yet one more layer hackers would have to get into to get your money.

Thanks for your replies but this seems to have drifted towards a computer/client-based solution.  Still wanting best way to generate paper wallet.  And best way to encrypt a flash drive (although I'm now seeing that it makes sense to use Armory/Electrum/Multibit for local large sum storage).  I probably will move towards Armory/Electrum/Multibit if I see myself needing to move significant funds around, but right now I just have big chunks in a safe deposit box and pocket change I use blockchain.info/mycelium/Satoshi client.  I can see the use of Armory/Electrum/Multibit if you draw from cold storage frequently.

I use OS X primarily but run Parallels for Win 7 and Ubuntu and boot to a live dvd for anything dealing with keys.  My qt is running on my old computer, just serving a node and don't really want to mess with the blockchain on my main machine.  And I just use Truecrypt on my external backup drives to keep them off-limits.

P.S. Armory/Electrum/Multibit use RNG to generate their addresses anyway, why not do a 99 dice roll brainwallet?

With BitAddress, I can see you kinda have to choose, I would rather keep my private key unencrypted (offline that is) than have it generated by RNG and encrypted.. (I hear great things from great people about the Armory wallet used on an offline computer, perhaps that is worth looking into)

Also, why TrueCrypt? Isn't Gpg more suited for this?

I think last time I looked into Armory it was windows only?  Doesn't it also fetch the entire blockchain?  I already run Bitcoin-Qt so maybe that's why I started exploring other options.  But I'll take another look...

As for Truecrypt, I'm just using it to encrypt a drive.  I'm not familiar with Gpg or encryption standards in general really.  Why would it be better?

Paste the private key under the 'Wallet Details' tab on bitaddress.org.  Make a change or three, then tell it to generate the new address.  If gives you an address, you made valid changes, if it says 'invalid private key', try some other changes instead.  There are just a few things you cant do, like using I, 0, l, 0,o.

I've used armory and the QT client to double check addresses, but it can be hard getting them to run off a live CD.  You could do all of this with a spare drive, then when you are finished, boot off the live CD and overwrite the drive with zeros several times.

But this won't work with a bip38-encrypted key will it?


Don't rely on RNG, use brain wallet option to generate a key pair


Likewise, this won't work with bip38 either.

I wonder if using bip38 offsets concern over bitaddress.org's RNG.

Also, what about my question about creating a Truecrypt flash drive?

Bitaddress.org could easily be compromised. 

Ask yourself:

How do you know the random number generator is truly random?
I would throw in a few manual changes to the private key it gives you.

How can I go about doing that while making sure it's still a valid address?  I know there is a checksum at the end or something but I don't know what I can change in the address.


How do you know the address are being correctly derived from the supposedly random private keys?
I would check the private key / address pair against other bitcoin software to make sure they match.

That's what I do at least.

Thanks, that sounds like a good idea.  Maybe grab html from brainwallet.org, bitaddress.org, and a third like

Paper wallets from Mac

First, please tell me if the following procedure for creating a paper wallet from my Mac sounds bulletproof:

1)Boot to Ubuntu live dvd
2)Run bitaddress.org html file from flash drive
3)Create bip38 encrypted keys from six-word, diceware-derived passphrase
4)Print keys with networkless label maker
5)Keep keys in safe deposit box

Is there anything wrong with this? Might anything be compromised? The bitaddress.org html file?

Next, I'm wanting to create a Truecrypt-encrypted flash drive as a secondary means of storage of paper wallet that I can keep at home. I haven't been able to figured out how to do it from the Ubuntu live cd while generating keys, although that would be ideal if possible. I tried having a linux truecrypt install file on the flash drive with the bitaddress.org html file but couldn't get that to work. So what if, after generating keys as per above, I:

1)Unplug my router and login as guest on my Mac
2)save keys in text file to Truecrypt-encrypted flash drive

Thanks!

Economics questions
by

on 25/04/2013, 04:23:43 UTC
While bitcoin is deflationary over the long-term, is it appropriate to say there is inflation in the short-term?  That is, while new bitcoins are being generated until 2140, is this addition to the money supply causing a degree of inflation?  This is my friend's question.  I told him I believe that any level of inflation is just slightly slowing the price increase of bitcoin and that, even during this period, the net effect is still that bitcoin is deflationary.  I don't have the economics background to answer him better.  That's why I'm hoping for someone with more econ background to help me out here.

Actually, this leads me to ask a second question: what is the general defense to economists' general argument against deflation as it relates to bitcoin.  How are people incentivized to spend, rather than hoard bitcoins?  Thanks!
