Becuase the transaction is on the blockchain it can't be reversed, right? And there's no legal recourse because all they've done is asked for a load of money and the server was cool with giving it to them?

Of course it can be reversed, all you have to do is get the majority of all miners that exist to agree to fork the entire blockchain to a point before that happened, rewinding time and reversing every other transaction that happened since that point



something that actually happened with bitcoin already

Lets put it in MMO terms cause most goons are super dorks and should understand them better.

If you are playing WoW, all your stats exist on Blizzard servers, instead of on your computer. This is because it makes it much harder to access you character file and edit in better gear, gold, or whatever you want. This is what it means to have your information stored server side. Now imagine if you were playing WoW, but all your character info was stored on your personal computer. In that case all you have to do is download a character editor and you can give yourself all the best gear and as much gold as you want. No one would actually raid because you could just hack in any gear you wanted. This is what it means to have your character saved client side.

Now imagine a bank. How dumb would it be to have your stats (how much money you had) to be stored client side. It would be pretty easy to hack your account file to say you had as much money as you wanted. This is exactly what this crypto service did, with exactly as expected results.

it's open bnet vs closed bnet

its really dumb, like a bank cashier not checking your balance when making a withdraw.
"Hello I would like transfer $100,000,0000 into my checking"
"Welp, it says it right here on the slip. You must be really rich!"

Embarrassingly, actual banks do this all the time. The Commonwealth Bank (one of Australia's largest banks) had an ATM error that allowed you to withdraw money you didn't have in your account. You didn't need to do an exploit, you just typed how much you wanted and it gave you it. A bunch of people were arrested for independently discovering this by accident and taking advantage of it. There are also a bunch of cases like this, where people discover the bank has hosed up and is allowing them to over draw millions and they can't resist the temptation.

No- definitely illegal but good luck catching them. This would fall under ‘unauthorized access’ which deliberately modifying provided code to break a system definitely falls under.

Much in the same way stealing a car that’s left unlocked and running is still illegal.

I'll make an analogy as if this were an actual bank.

At a normal bank you go up to the teller and hand them your identifying information, such as an ID. The teller then verifies that information and asks how much money you'd like to withdraw from your account. You tell them and they hand you the money.

In this analogy you are the 'client side' code and the teller is the 'server side' code. The client side code generates the identifying token because obviously the server doesn't know who you are and then passes the information to the server. The server then verifies your identity and your balance then hands it back to you.

How they coded it in this case would be like you walking up to the bank and making a withdrawal- only the teller would just hand you whatever money you asked for because it was up to you to verify the amount of money in your account. Even if you didn't have any money left or even a negative balance they wouldn't stop you from withdrawing more.

When people say 'client side' code they mean code that's literally running on your own computer- not the server. They have no actual control over what happens on your machine. If you're a programmer or someone who knows how to fiddle with web browsers it's trivially easy to change the code on your machine to whatever you want. This is web services security 101 level stuff and the fact they screwed this up means they are either 'babies first web project' level amateurs or deliberately left the flaw so they could 'steal' the coins from themselves.

Isn't this the entire point of the blockchain

A blockchain,[1][2][3] originally block chain,[4][5] is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[1][6]Each block typically contains a cryptographic hash of the previous block,[6] a timestamp and transaction data.[7] By design, a blockchain is inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[8] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

Not by design, no. Wallets (and bitcoin balance) are not inherent to the blockchain, but an abstraction put on top of it. Normally, people use a single bitcoin address for receiving butts, but there's no reason this has to be so. You could easily generate a new address for each transaction.

That means that while you could track the transactions, you would necessarily be able to show that the same person spent butts received from two different transactions. With a bit of correlation analysis, you could get a pretty good idea, though.

Even then, bitcoin doesn't necessarily require you use wallet addresses for identification; the entire system is designed with transactions issuing challenges. Wallet addresses are just the standard challenge. Aside from a piece of code introduced later enforcing that only a fixed set of challenges are legal (because of course they were exploited), there's little standing in the way of making much less traceable transactions.

TLDR: Bitcoin is far from anonymous, but that's not inherent in the system.

I mean its semantic and the same vocabulary nuance exists with Tor. It doesn't make you "anonymous" per se, but it separates your identity as a individual human from your identity as a set of transactions/web requests until such time as someone has a way to connect it back to you.

I don't know if carrying a million dollars in cash on your person in order to give it to someone is that great of an idea. I mean, like it or not it's a historic fact that bitcoin was used for organized crime because it's harder to track, easier to launder, and more convenient than other methods that existed 2+ years in the past.

Is it historic fact? Seems dubious. It's certainly harder to track than electronically transferring real money. But I assume most organized crime never laundered their money through Bitcoin.

I mean you can just ask this question: why did Silk Road use bitcoin? There isn't an any possible answer that doesn't involve the relative security improvement over other transfer methods and the illegality of what they were selling. Silk Road is also a great example because of how Ross Ulbricht failed to maintain separation between his real identity and the publicly known transactions on the blockchain. Once the investigators found him using his personal email they could immediately prove that he accepted like 30 million in BTC for illegal drugs.

Traditionally, that's why organized crime does something called "laundering" money through businesses that act as fronts. I find it hard to believe Bitcoins has been used at large scale for this.
