184 million bitcoin bug
A bug Allowed the Issuance of 184 Billion Bitcoin, Ten Years Ago
The few that claimed their coins are thought to have immediately sold them off and the price of the coin never recovered after plummeting on its first day in circulation. As a result it was vulnerable to attack from anyone with a modest amount of computing power at their disposal. Here are two good post-mortems of the entire fiasco , which go some way to casting doubt on the viability of alternative cryptocurrencies. Speaking of which…. For the last eight years, a bunch of Scottish developers have been quietly beavering away up in Fyfe creating what they see as the future of the Internet — totally decentralized, encrypted and anonymised.
But what were they selling, I hear you ask? A temporary cryptocurrency, which will one day be exchangeable for the permament cryptocurrency running on the Maidsafe network. Confused yet? You could only participate in this cryptocurrency crowdsale with bitcoin or another cryptocurrency, mastercoin.
Why risk your crowdsale by allowing people to buy in with a practically worthless cryptocurrency like mastercoin? One transaction, totalling only 0. Something similar happened to this hapless Redditor , who made a simple typing error back in July , attaching 30 bitcoin to a 38 bitcoin transaction.
The Day Someone Created 184 Billion Bitcoin
But until then, people will continue to accidentally add incorrect transaction fees or even transfer bitcoin to defunct Mt. Gox addresses. There are many many more stories like these. Too many to include in one piece, but let us know your favourite stories of bitcoin woe in the comments below. Let the schadenfreude flow through you.

The 9 Biggest Screwups in Bitcoin History. Facepalm image via replygif. Trek-palm image via Giphy. This doubles the maximum integer to 18,,,,,, eighteen million trillion. Trying to store a number bigger by even just 1 would cause an integer overflow. Imagine a car's odometer:. Once it reaches , another kilometer won't set it to because there's no room to show that number.
It'll go back to The exact same thing happens with numbers in computers — once they surpass the maximum integer value, they overflow and reset to 0. Bitcoin currently has 8 decimal points. The smallest Bitcoin fragment is called a Satoshi. The theoretical maximum number of bitcoin is 21 million, so 2,,,,, two quadrillion one hundred trillion Satoshi.

If we cut off the last 8 digits from the maximum integer that can be stored 18,,,,,, so it matches Bitcoin's protocol, we get: ,,, In other words, because of its decimal points the biggest possible value in the Bitcoin protocol is actually a little over billion instead of the full eighteen million trillion. But in , the software had a critical bug.
When sending BTC from addresses to addresses in Bitcoin it's actually possible to send from multiple addresses to multiple addresses , the software was checking for total input values and total output values, but not the things that happen in between. During one such transaction, the perpetrator gave the program the following instructions simplified for easier understanding :.
The sum of the A and B transactions was ,,, That's exactly Satoshi away from the maximum. Other amounts in the transaction combined with this number caused an integer overflow and the total amount fell to just Address A and address B each got billion completely valid bitcoin, even though at the time there were only around 1.

Satoshi, Theymos, Jeff Garzik, and others who noticed this weird transaction quickly started thinking about solutions out loud. In the span of a few hours a patch was written for the code to fix this issue for future transactions, along with a proposal to roll back and undo the transaction that occurred.

This patch was added to the Bitcoin Core software — the node which signs and sends transactions. The update, Bitcoin patch 0. The rapid implementation of the patch was vital in keeping Bitcoin a viable cryptocurrency. Even if the breach happened today, the amount of bugged Bitcoin would completely dwarf the current supply of the cryptocurrency, making any Bitcoin worthless.

Due to the ability to easily audit the supply it was noticed quickly; bug was patched in 5 hours. Bitcoin also benefited from this exploit being patched close to its inception, since taking the Bitcoin network offline could be done without significant consequences.
Today, such a disruption would cause widespread chaos; trading would be heavily disrupted and any purchases that were made using Bitcoin would have been canceled. The very fact that a bug could enable the 21 million Bitcoin limit to be breached would also create shockwaves in the crypto community, likely causing the price of Bitcoin to collapse and fatally undermining confidence in the cryptocurrency.
That Satoshi himself intervened, and did so so quickly, showed that Bitcoin was not as easily hackable as some might have assumed and built confidence in a concept which up to that point remained untested. To this day, the person behind the exploit remains unknown, and due to the anonymous nature of the blockchain there is no way to trace them.
