1921  Economy / Service Discussion / MtGox source code leaked ... on: March 03, 2014, 05:17:39 PM
http://www.techworm.net/2014/03/mtgox-source-code-leaked-by-hacker-on.html

As a developer all I can say is ...
I have nothing to say just stunned silence that this was the codebase used to process millions of dollars and BTC everyday.

Any updates? I'm losing hope Sad

Your losing hope?  It is a scam.  It always was a scam.  You give them Bitcoins, they give you nothing.  The system is working exactly as they intended.  I mean you have 5+ pages of documented evidence of a scam.  Why would a scammer who already robbed you of your bitcoins clean, give them back?

I'm sure all of those coins could be coded out of circulation, but the point of bitcoin is this exact thing. Non reversible there are many red flags, and warning signs everywhere about bitcoin safety, and infancy.
We don't need to change the rules and ban the stolen coins. We can simply forget Old Bitcoin and start New Bitcoin, with exactly the same rules, mining hardware and same infrastructure.
If more than 51% of the current bitcoin users do that, the Old Bitcoin will simply fade away...

It has already been done multiple times both exact copies of Bitcoin and modified version (commonly called altcoins).  You are free to do it again at anytime but people are also free to ignore such attempts.

So let me know when you launch "newBitcoin".

Bear in mind that a lot of the time these societies are actually more willing to accept virtual currency.

For example, M-Pesa usage in Africa is more widespread than traditional bank accounts, so people are already accustomed to using their mobile phone to settle bills ins tores and transfer money between individuals.

http://www.bbc.co.uk/news/business-11793290

M-Pesa works on really old phones, unlike a bitcoin wallet, but you can see the potential.
Agreed its cheapest way to send money for them.

I wouldn't say cheapest more like only.  Fees using mpesa range from 3% to 11%+ (above the cost of phone and cellular plan).

Good point.

Ironically is that happened it would reduce regulation as Dealer if Foreign Currency is generally less regulated at the state level than money transmitters.  Come on Somalia make Bitcoin your legal tender.
1926  Bitcoin / Development & Technical Discussion / Re: Forking Blockchain for lost keys on: March 03, 2014, 03:59:20 AM
Users can choose, but, unless it faults the checkpoint system that bitcoin has in place (here's a list), then, by default, bitcoin-qt/bitcoind will auto-jump to the longest, valid, chain. In this case, assuming miners can generate a longer, valid (But ignoring gox's transaction), chain before the miners on the current chain can extend it, then, we'd all auto-jump and orphan the other blocks.

Each clients will independently select the longest VALID chain using the internal rules of the client.  An invalid block can never be in the longest chain.  A client on the current fork would see ANY "the gox block" as invalid and it would also see any block built off that blocks as invalid as well.  It would never be the valid longest chain even if it had a billion more blocks than our current longest chain.  Miners aren't the only element of the security model in Bitcoin.  Each node independently verifies all data according to the rules in that node and discards data which it deems is invalid.

Try imagining a simpler scenario, a miner mines a block with a trillion BTC reward.  By your statement above as long as it doesn't break the checkpoints and is in the longest chain all nodes would be forced to use it. A super cool way to mint a trillion new BTC into existence and an attack which would obviously have been attempted by now.  I think you can see how flawed that security model is.  Thankfully Bitcoin doesn't use a "miners are gods and anything they give us must be obeyed" security model, it uses a "trustless" security model where each node implicitly distrusts information received from other nodes until the node independently validates it.

So someone can make a "BailoutCoin" client and some miners (maybe even 51% or miners) can start mining that chain.  However the current chain will see blocks on that chain (after the bailout block) as no more valid than Litecoin blocks are valid on the Bitcoin network.  You can't force all users to use the new "BailoutCoin" client so users will have a choice (much like they do with 100+ altcoins today).

You can never changed Bitcoin all you can do is fork it and convince people to use the fork.  Unless 100% of users accept the new fork, then the existing fork will also co-exist.

I admit, I didn't just read the entire bitcoin source, so, I'm going mainly off comments & function names.

No offense but that is obvious.

MtGox starts an IPO of 500 million dollars

IPO probably doesn't mean what you think it does because no Bitcoin related company has ever had an IPO.  The timeline for a public offering is measured in years and requires solid revenue, operating history, and a minimum capitalization.  MtGox doesn't meet the criteria for listing on any exchange, and is currently in bankruptcy so that is dead in the water.

In the real world an Initial Public Offering isn't something done trivially.  Even coinbase or bitpay have no shot of an IPO today, maybe in a couple more years if they continue to be well run, and grow their businesses.

You may mean a private placement?  A debt for equity swap is one method of funding a private placement.  There are two issues with that, the first is private placements are limited to accredited investors and in Japan they are limited to 49 shareholders.
1928  Bitcoin / Bitcoin Discussion / Re: when will the fee reduction go through? on: March 03, 2014, 01:31:40 AM
No idea although there is no guarantee that some or any miners will accept tx with a fee as low as 0.01 mBTC.  The more relevant question would be to ask the mining pools what their fee policies are and if it will change once v0.90 is released.
1929  Bitcoin / Bitcoin Discussion / Re: Just about the best explanation of Bitcoin for newbies ever! on: March 02, 2014, 11:33:11 PM
If by "best" you mean completely wrong on multiple levels and utterly useless then yes it is the "best".  Nothing wrong with simplifying a concept but if you do such in such a manner that you make completely false statements that kinda defeats the purpose.

1930  Bitcoin / Development & Technical Discussion / Re: Forking Blockchain for lost keys on: March 02, 2014, 10:28:51 PM
It would be possible by creating a block number n and all miners agree to include this block. The only thing in this block would be a transaction to a new address and the destruction of the gox coins. So at an agreed time this would become the next block and miners would carry on mining the blocks after that.  This is obviously only if they are lost and the addressees known.

Its a terrible idea for obvious reasons and any one thinking this would be a positive for bitcoin clearly do not understand it.

All miners is not sufficient to change the Bitcoin protocol it requires all users, all existing clients to be upgraded.  Otherwise there is a fork and users will choose the one they want to use.
1931  Bitcoin / Bitcoin Discussion / Re: when will the fee reduction go through? on: March 02, 2014, 09:53:21 PM
Each node works independently.  Any node running v0.9 will relay tx with only a fee of 0.01 mBTC per KB (vs 0.1mBTC per KB for v0.8.6).  The network will have nodes on different versions but once a significant majority is running v0.9 or later will become reliable to relay tx with a fee that low.

Of course miners are free to set whatever fee requirements they see fit (even larger than 0.1 mBTC if they want) so being relayed is no guarantee the tx will be included in the next block.
1932  Bitcoin / Legal / Re: Country XXXX declares Bitcoin legal tender. What happens next? on: March 02, 2014, 09:50:55 PM
None of those things.

The declaration of legal tender would apply only to that country and only in a very limited scope. 

In the US legal tender means it can be used to pay debts, damages awarded by courts are denominated in legal tender, and legal tender is only accept method to pay tax liabilities. Nothing more.

Outside of that extremely small scope you can use other currencies in the US.  For example a shop in the US could accept Euros, pay customers in Euros, issue invoices in Euros, have Euro denominated bank accounts, etc.  A shop can even refuse to accept payment in US dollars (but not for debt). 

So legal tender has a very limited scope and Bitcoin could (not saying it will) become the most used currency in the world without being legal tender in any nation.
1933  Bitcoin / Bitcoin Discussion / Re: It is possible to make a ZERO spend with Bitcoin? on: March 02, 2014, 09:36:01 PM
To the OP you can not perform a spend of zero.  Bitcoin doesn't work on the concept of balances it works on the concepts of inputs and outputs.  When you make a transaction it has one or more inputs which are references to the outputs of prior transactions.   You can't spend part of an output you either spend it or you don't.

You could however spend right back to the same address however as others pointed out that would make the public key known and in theory if ECDSA was weakened or degraded could allow the private key to be compromised in the future.

The better option would be to sign a message with the private key and use a third party implementation (like say QT client) to verify that signature.  If the signature is valid then the relationship between your private key and public address are valid.
1934  Bitcoin / Bitcoin Discussion / Re: It is possible to make a ZERO spend with Bitcoin? on: March 02, 2014, 09:32:22 PM
Transactions below 5430 satoshis are not valid and won't get confirmed anyway.

Care to explain why I did recieve an amount of BTC 0.00000001 ?


Is it confirmed?  Tx below 5430 satoshis are not invalid that is incorrect.  They are however non-standard and as such miners will not include them in blocks by default and nodes will not relay them by default.
1935  Bitcoin / Development & Technical Discussion / Re: Forking Blockchain for lost keys on: March 02, 2014, 08:52:09 PM
OP proposal is not possible, even with 51% of the mining power behind it.

As dexX7 correctly pointed out, without knowing the private keys to the transactions, any transaction of the coins to a new input would invalidate the block (and any subsequent blocks). No client would accept this invalid chain, regardless of length.

I'm not sure why this proposal has cropped up multiple times a day since the mtgox incident. One almost suspects that there is an ongoing influx of new users who are unaware of the forum's search function.

It "can" be done, anything can be done.  The rules of the network are enforced by the client anyone can make any change they want to the network.  A miner could decide to make the block reward 1 million coins per block.  Technically it is brain dead easy to make these kinds of changes.  Change a couple lines of code, compile, and distribute.

You would create a fork of the network.  The real question is can you convince anyone to use this (or any other controversial change)?  My belief is no, or not is a large enough numbers to create a critical mass.  However nobody can stop anyone else from doing it, and it certainly "can" be done.  So those who want to do it, just go ahead and do it.  See how many people use this "gox-coin".
1936  Economy / Services / Re: You use PayPal/credit card & buy domains for me from GoDaddy, I pay you Bitcoin on: March 02, 2014, 02:43:06 PM
Are these existing domains or new domain registrations?

If it is the later why not just use namecheap (they accept bitcoin deposits).
If it is the former use BitSimple to sell coins, withdraw to your PayPal account and pay for it that way (go daddy accepts PayPal).

If it is a large amount (expensive domain) and it needs a CC I am sure I can help you out but I am traveling today so if you don't find anyone else trusted drop me a PM this evening.
1937  Bitcoin / Bitcoin Discussion / Re: Why the suggestion to change wallets/addresses often? on: March 02, 2014, 02:24:31 AM
The best I can do is:

"One of the most recent 2 Lets Talk Bitcoin Podcasts"

Andreas discusses it.  Or maybe it was that 2 hour interview he just did with Stephan.

Then I will stick with you are misinterpreting a statement and they never said what you claim they did.

There is absolutely no reason to change wallets "often".  Addresses shouldn't be reused but that is different from what you claimed they said.

1939  Other / CPU/GPU Bitcoin mining hardware / Re: Residential Limit 15amp or 20amp? on: March 02, 2014, 02:01:17 AM
Is the claw rated for 240 volts? Usually they look for the inductance based on a single hot (120), not two hots (240)

Just a thought.

C

I have never seen a clamp meter that is rated for less than 600v, and that rating is for arc hazard and has nothing to do with accuracy.  amperage is amperage doesn't matter the voltage.
The trick though is these devices measure the differential in current as measured by a magnetic field around the wires. Stronger the field, more amps. However that assumes a hot and ground, I think you have two hots.

Whatever, good luck.

Two hots makes no difference in the current (and thus magnetic field  and thus reported current).  Two hots increases the voltage.  The two 120V hots are out of phase so there is 240V potential between hots and 120V between either hot and the ground.
1940  Economy / Service Discussion / Re: Open Letter to Mark Karpeles: Voluntary Reorganization Best Option for Us All on: March 01, 2014, 11:23:09 PM
The problem is if there are a lot of money lost, there is a chance everyone will get a very small percent.
 The original OP plan has a better chance to recover all the money for everyone. Of course it will take time, perhaps years.
 But if the lawsuits go through it will take years ANYWAY but everyone will get pennies.

The problem with the OP is that it ignores factual reality.  MtGox is in bankruptcy (protection), it can't leave that status until the courts agree.   Naming a couple hundred thousand (mostly unaccredited) shareholders to a private company isn't legal in Japan (or most places) and the courts are going to sign off an an illegal re-organization.
