Buttcoin crash, lag, mt. gox, shitty, terrible 6 Comments April 3, 2013

Bitcoin jumped from around $120 last night to over $140 this morning and of course Magic The Gathering Online eXchange shit itself because it’s run by a closet brony.

mtgox-dead

 

 

This is a company that makes $60k per day on average (more than $100k now with the price spikes and rise in volume) and has 18 employees but they can’t get a fucking server functioning for shit. Every time the price starts to drop Mt. Gox lags to the point of being unusable. Either they’re incompetent or are manipulating the price. Higer price = Bigger profits.

 

Can’t someone save the free markets!

Buttcoin bitcoin bubble, crash, economy, fake, growth, pop, real 13 Comments April 1, 2013

For those that don’t know, there was some news a while back where the Bitcoin enthusiasts were excited about having an electronics store that specialized in bitcoins, which “proved” that bitcoins were slowly becoming a legitimate currency for legitimate transactions.  But has anyone actually checked out the site?

https://www.bitcoinstore.com/

Normally, transparency is very difficult in the bitcoin world.  But bitcoinstore is a special case, because they need to hit a certain dollar amount with their supplier in order to maintain the best possible discounts.  Since they are nowhere close to reaching their goal, they put up a live chart on their website to show viewers how far they need to go.  At the current market rate of $77, bitcoinstore has raised about $363,000.  They need to hit $850,000 by March 31st, three days from now.  This implies that they currently have around 4700 bitcoins in their wallet, or about 0.04% of all bitcoins in existence (1 in every 2,500).

From February to March, bitcoins essentially went from a low of $20 to a high of $95.  That means that they essentially created $800 million in market value from thin air.  For every dollar spent at the bitcoinstore, the market value of bitcoins has increased by $2000.  This completely destroys the argument that the price of bitcoins are going up for any reason other than speculation.  People are speculating on the idea that bitcoins are a useful currency, but the simple fact of the matter is, no one seems to be using them for anything other than silk road.

 

btc-1-yr

1 year price history of BTC

 

Here’s another bit that’s interesting:

http://www.businessinsider.com/price-of-a-bitcoin-passes-90-dollars-2013-3

Notice how even as the price is going up, the number of actual transactions has gone down? This pretty much destroys the idea that bitcoins have gone up due to heightened interest.  Instead, it implies one or both of the following:

1)  The lack of transactions is causing the price to go up.  Speculators hoard their bitcoins in the hopes of future gains, which creates artificial scarcity and a self-fulfilling prophecy.

2)  The price going up is causing a lack of scarcity.  This would imply that the price is going up due to manipulation, rather than actual interest.  As the price goes up, hoarders are less likely to sell (due to greed), and buyers are less likely to buy (because it’s too expensive).

Since bitcoins generally have no accountability, such manipulation would be impossible to investigate.

We should also note that the $800 million increase in market value is purely speculation.  In other words, just because you have 11 million bitcoins each valued at $95, that doesn’t mean that you will actually be able to sell them at that price.  Which is precisely what happened here.

One of the major problems with the bitcoin economy is that the current market price is based on the current trading price, and trade volume is easy to inflate.  You simply pass some money back and forth between different wallets, so that the market looks more active than it really is.

Imagine if an author wanted to get on the bestsellers list, so he sets up two separate book stores.  Bookstore A purchases 100 copies from Bookstore B, and then Bookstore B purchases those books back from Bookstore A.  As long as there’s no sales tax, this can go back and forth indefinitely to make it look like millions of copies were sold, even though you only had 100 copies to start with.  Bitcoins are never actually consumed.  They’re not a good or a commodity on their own.  Instead, they can only pass from one hand to the next, and we have no way of knowing if these transactions are legitimate.

50366633_3f45a898ebThis brings up another point:  If Bitcoins can be re-used an infinite number of times, then you can’t really attribute the skyrocketing price to supply and demand, because the supply is essentially infinite. There is absolutely no reason for the price to go up so dramatically, other than greed and speculation.

In other words, the economy of Bitcoin is not growing in any meaningful way, and it will stay that way in a deflationary economy. Why spend Bitcoins when holding them will produce grater rewards? Any growth in the economy is due to the simple movement of coins back and forth, not due any type of exchange between Bitcoins for goods and services.

The fact is this bubble is undeniable and with no real growth to be seen the instability will increase until everything collapses again.

Bitcoins crash from $94 to under $80 in the last hour with no sign of slowing down.

/r/Bitcoin and BTCTalk are in a panic, tons of buy orders coming through right now.

 

Only thing preventing a major panic sell is the fact that Mt. Gox has 10 minutes of trading lag. You aren’t trading bitcoins, you’re trading on what you think bitcoins will be in 10 minutes. This is some serious shit.

Buttcoin bubble, crash, new high, paradigm 4 Comments March 27, 2013

Today Bitcoins hit $88 (and went up and then down and then up again) which is an important milestone because it allowed me to write this witty title.

I think we’ll probably hit over $100 by the end of the week or mid next week. My opinion is that we’ll see a little over $100-$120 before the crash comes again, but I’m terrible at predicting these things.

 

So instead I’ll post these 4 simple signs that you’re investing in a bubble.

There are four signs that can help you recognize that an investment is probably in a bubble:

One of the major signs that an investment is headed into bubble territory is a skyrocketing price. The price might be shooting up quickly, seeing rapid appreciation. There doesn

Silk Road fumbles and reveals its IP address

killhamster bitcoin, buttcoin, crash, drugs, fail, security, silk road 5 Comments March 26, 2013

A bored pentester used this one weird old trick to find out Silk Road’s public IP address, which has the potential to compromise the entire operation.

EDIT: Don’t go into freak-out mode here! This is potentially serious, but is fixable and I disclosed to DPR alone about 15 hours ago. He’s good, skilled, and this will be investigated and fixed in no time, I am sure. In the interim, if you need to use Silk Road BE SURE TO USE GPG. The beauty of Bitcoin and Tor is that even if the server were to be seized, if your messages are GPGed, it’s near-impossible to get anything valuable. I just know that not everyone uses GPG.

I am a penetration tester by trade, and while I do not use SR, I do occasionally conduct informal tests of the security of various Tor Hidden Services.

I debated for hours whether to post this, but I need to alert the community in case no actions are taken:

Last night, while SR was down for maintenance, a brief few moments allowed a certain set of circumstances that caused me to be able to view the public IP of the httpd server of Silk Road. This isn’t an obvious flaw, but it is extremely simple if you know where to look – the server basically will publish a page containing all of the configuration data of the httpd server including the public IP address.

For the sake of the site’s security, that’s all the information I’m going to reveal.

I have messaged Dread Pirate Roberts and am currently waiting a response. I do have a SHA512 hash of the public IP which I have retained as evidence if DPR needs proof.

I will keep this updated with any news received.

With such information, authorities may be able to locate and shut down Silk Road and apprehend its operator, or more. What does this mean for Bitcoin? If the Silk Road gets busted, the only thing left to prop up the price of butts is the Magic: the Gathering Online Exchange’s creaky servers and meddling hands.

Buttcoin bitcoin, cool, mining rig, nes, useless 1 Comment March 24, 2013

Mersenne from Something Awul turned us on to this hilariously useless but kinda neat project.

So apparently some guy developed a hilariously roundabout method for mining Bitcoins on a NES.

 

nes-bitcoin-miner
Of course, like most things Bitcoin, this is only technically true:

*Communication with the Bitcoin network

This part is pretty simple. I’m using bitcoind to do the network communication. This is pretty standard for bitcoin mining, the mining software focuses on doing the hashing and lets bitcoind do the p2p network stuff. There’s a few standard protocols for those two pieces to communicate with varying levels of efficiency, but I’m using the most basic ‘getwork’ protocol because, heh, this isn’t going to be the bottleneck in this operation.

For the portions of computing that do not happen on the NES, I’ve got a raspberry pi housed in a Makerbot Replicator2 3D printed case. I believe I am now fully 2013 Hack Project compliant.

Raspian’s repos were serving some crusty version of arm bitcoind, so I compiled my own from the latest source. This is not hard, except that my rpi has 256MB of RAM and g++ just gives up when its all filled up. I’m sure there’s a more elegant cross-compilation environment available, but adding a 2GB swap and letting it crank all night worked for me.

*Data in

There are a couple pieces involved in getting data into the NES, many of which I’m just pasting together from other people’s code. They deserve the credit for their respective projects.

First, I’m using a python implementation of the mining protocol by jgarzik (https://github.com/jgarzik/pyminer) to do the jsonrpc communication out to bitcoind and basic structure.

Next, I’m using a NES that I modified with a USB CopyNES (http://www.retrousb.com/product_inf…&products_id=36). Inserting this board inbetween the NES’s mainboard and processor adds a USB port to an NES that affords for lots of development capability, including the ability to write to RAM carts. The RAM cart I’m using is a PowerPak Lite, also from retrousb.com (http://www.retrousb.com/product_info.php?products_id=35)

For the USB serial communications to the NES I’ve gutted and hacked up mstrand’s script (https://github.com/mstrand/copynes)

So the rpi getworks a chunk of data, wraps it up into a ROM (detailed below), and sends it to the console using via USB CopyNES.

*Doing the hashing

SHA256 hashing uses many 32-bit operations, and the 6502 in the NES is an 8-bit CPU. Initially I thought this would be a significant challenge, but with some modifications, I got an open implementation of SHA256 to compile to a 6502 target using the cc65 compiler (cc65.org)

The rpi getworks a chunk of data, compiles it into a ROM that includes the SHA256 algo and current target data, and sends it to the console via USB CopyNES.

Each ROM computes and tests a single hash.

*Data Out

After the NES computes and tests the hash against the target value, the NES knows if this iteration was a success. But we need to pass successes back out to the bitcoin network.

If the generated hash is less than the target value, the background color of the screen will be green, otherwise it will be red. A Playstation Eye camera pointed at the screen takes a picture and, using OpenCV, checks for the predominant color in the image.

If there’s more green than red in the picture that the webcam snaps then it gets reported out to the bitcoin network as a success. If not, then we start the process over again with a freshly grabbed chunk of getwork data.

(emphasis mine)

So to recap: This guy is using a Raspberry Pi to pull transaction data from the network, packs it into a ROM containing a built-in SHA256 implementation and a single hash, and copies it via USB into a flashcart. The NES then computes and displays the result, and depending on the background color the webcam pointed at the screen reports this result back to the network as either a success or failure.

Again, all of this is for a single hash.

It’s even better once you actually see the thing running in that video he posted. If you count the time between screen refreshes, that setup is chugging along at approximately five hashes a minute, or 0.083 hash/sec.

At the current difficulty level, the average time per block would be 10,987,004,979 years, or more than twice the age of the earth. Truly the next generation of mining rigs!

Buttcoin bitcoin, increase, money, price, raise, rich, rise 5 Comments March 21, 2013

Bitcoin is on an unending march towards mainstream adoption and with that, $100 bitcoins are nearly here. We just had a $10 jump in the last 12 hours and it’s obvious we’re on a run away freight train to the currency of the future.

I would like to formally apologize to anyone I doubted. I am truly jealous of everyone’s sage investment strategies and now I’m stuck with my dick in my hand while everyone else is getting rich. Are we going to see $1000 in the future? The captains of industry tell me so.

Why SatoshiDice, Bitcoin’s biggest success, will eventually kill Bitcoin.

killhamster bitcoin, buttcoin, crash, fail, gambling 10 Comments March 12, 2013

For the uninitiated, SatoshiDice is a Bitcoin gambling site described as a ”blockchain-based betting game,” accused of being a DDoS against Bitcoin by Luke-jr (notable for his fanatical devotion to “Tonal Bitcoin,” which as far as anyone can tell is actually a joke.) Users send an amount of their bitcoins to a SatoshiDice address, the “service” then determines whether the “bet” wins or loses, then returns a transaction with winnings or a fraction of the house winnings, since they’re such great guys.

 

PBF045-Wise_Satoshi

The “bets” on SatoshiDice generate a tremendous volume of microtransactions (each bet takes two transactions to complete,) which spam up the Bitcoin network, and those who play SatoshiDice pay elevated transaction fees (which are, for the most part, ignored or not paid by many users,) and as a result SatoshiDice transactions receive priority when processed, forcing other transactions to wait for the next block. SatoshiDice transactions account for most of the content of the blocks generated now and its transactions filling blocks helped contribute to the blockchain fork, which caused chaos and allowed someone to perform the infamous double-spend attack. This problem has been known for at least a year yet nothing was done to patch or prevent SatoshiDice from forking Bitcoin.

The chart below illustrates the damage SatoshiDice does to Bitcoin.

The vast majority of the blue markers are SatoshiDice and because they pay the transaction fee, they have priority over normal transactions and are effectively choking out the rest of the economy and causing long delays in confirmations.

Buttcoin crash, down, flash, flawed 10 Comments March 11, 2013

Major software flaw with bitcoin is tearing the protocol, and the markets, apart. From Hackernews

Ok, here’s what happened and what it means. Bitcoin is built on a chain of blocks, each of which contains a set of transactions, the hash of the previous block, and a cryptographic proof-of-work which takes a lot of computing power to construct. Whichever block-chain is highest (that is, has the most total computing power invested in it) is considered valid, and has more blocks added to it by miners. People “mine” by taking outstanding transactions, writing them into a block together with the hash of the current highest-numbered block, performing cryptographic proof-of-work and publishing their new block.

A block was mined (by the Slush mining pool) which is accepted as valid by 0.8 clients, but rejected by 0.7 clients. More than half of the mining power was on 0.8, so the longest chain includes this block – but the 0.7 clients reject it, and have built a side-chain. The developers have asked all miners and mining pools to switch from 0.8 to 0.7, so that the 0.7 chain will grow to be longer than the 0.8 chain; once this happens, all Bitcoin clients will agree that it is the real one. In the meantime, however, merchants running Bitcoin 0.8 may be targeted by double-spend attacks: if they receive money in a transaction that exists only in the 0.8 blockchain, the same money is spent in a different way on the 0.7 blockchain so the transaction can’t just be copied over, and they act on the receipt of money by sending goods before the situation is resolved, then they could lose money. This is why MtGox has suspended Bitcoin deposits. (This can only happen if the coins were sent by someone who is using malicious, nonstandard software; transactions made by honest users will be copied to the 0.7 fork and mined without any issue.)

The height of the two chains can be monitored at https://coinbase.com/network/blocks . Currently the 0.7 chain is 13 blocks behind, which (since the normal mining rate is 6 blocks per hour) sets a lower bound of about two hours on resolution – assuming everyone switches their mining power immediately – but realistically it will probably be more like 6-12 hours.

Yet another Bitcoin business is hacked; BitInstant loses $12k in social engineering scam

Buttcoin bitinstant, hack, lost, money 1 Comment March 9, 2013

You may have heard the news by now, but popular Bitcoin payment provider BitInstant was hacked last week. It wasn’t a massive hack like we’ve seen on MyBitcoin or Mt. Gox so I didn’t see much reason to write on it when I saw it 3 days before Wired’s article, but as I looked at it more I figured I’d point out some interesting points.

First, the hack was a regular social engineering hack. Really simple stuff.

Over the weekend the BitInstant team has been hard at work securing our system from a sophisticated attack on Thursday evening. Overall, due to major choke points and redundancies in our system, the hacker was only able to walk away with $12,480 USD in BTC, and send them in 3 installments of 333 BTC to bitcoin addresses.

…

The attacker contacted our domain registrar at Site5 posing as me and using a very similar email address as mine, they did so by proxying through a network owned by a haulage company in the UK whom I suspect are innocent victims the same as ourselves. Armed with knowledge of my place of birth and mother’s maiden name alone (both facts easy to locate on the public record) they convinced Site5 staff to add their email address to the account and make it the primary login (this prevented us from deleting it from the account). We immediately realized what was going on, and logged in to change the information back. After changing this info and locking the attacker out, overnight he was able to revert my changes and point our website somewhere else.

…

After gaining access, they redirected DNS by pointing the nameservers to hetzner.de in germany, they used hetzner’s nameservers to redirect traffic to a hosting provider in ukraine. By doing this, he locked out both my login and Gareths’s login and they used this to hijack our emails and reset the login for one exchange (VirWox), enabling them to gain access and steal $12,480 USD worth of BTC.

BitInstant is shifting the blame totally on the host. Never mind the fact that they used real, publicly accessible information on of the owners wide-open Facebook page, this is totally the host’s fault.

Site5 has since responded since the hack.
