Dear Ofir, I mean you no disrespect or neither do I harbour any ill feelings towards you. If you could review quantumhash. So, moving on from the biggest attack that rocked Bitcoin, to the biggest attack that Ethereum has faced till date. The attack and its aftermath were so severe that the developers were forced to create a whole new currency to deal with the repercussions!
The entire ecosystem of Ethereum works on the basis of smart contracts. For the uninitiated, smart contracts are basically how things get done in the Ethereum eco-system. To put it in layman terms, smart contracts are automated contracts that enforce and facilitate the terms of the contract itself. It was basically going to be a decentralized venture capital fund which was going to fund all future DAPPS made in the eco-system.
The way it worked was pretty straightforward. Well, firstly they need to get whitelisted by the curators, who have basically known figureheads in the Ethereum world. After getting their stamp of approval they will get voted on by the DAO token holders. The potential of the DAO and the flexibility, control and complete transparency that it offered was unprecedented, people leaped in to get their share of the pie. There was one condition in the contract, however, after splitting off from the DAO you would have to hold on to your ether for 28 days before you could spend them.
So everything looks nice and spiffy for now…. A lot of people saw this possible loophole and pointed it out. The DAO creators assured that this was not going to be a big issue.
The only thing is, it was and that created the entire storm that split Ethereum into Ethereum and Ethereum Classic. The loophole that the hacker s discovered was pretty straightforward in the hindsight.
If one wished to exit the DAO then they can do so by sending in a request. The splitting function will then follow the following two steps: What the hacker did was they made a recursive function in the request, so this is how the splitting function went:.
The hack happened because of an issue in the DAO not because of any issues in the Ethereum itself. Ethereum runs in the background while DAO runs on it. The Ethereum community got together and decided that a soft fork was the best way to go forward.
However, during implementation, the developers realized that a soft-fork would result in a lot of DDOS Denial of Service attacks. The only other option was to hard fork the chain and this split up the community. The second biggest in the history of bitcoin was suffered by Hong Kong-based cryptocurrency exchange platform, Bitfinex. Bitfinex announced the hack on August 2, Before we understand how and why the hack happened, we need to refresh some concepts first.
The easiest way of understanding how a multi-signature multi-sig wallet works like is by thinking of a safe which needs multiple keys to operate. A multi-signature wallet is great for 2 purposes:. How does multi-signature wallet save you from human error? They issue 3 private keys. So even if you have a hacker behind you, it will super difficult for them to get their hands on 2 private keys. And on top of that, even if you lose your private key for whatever reason, you still have that backup key that you had given to your friend.
Now, how does a multi-signature wallet create a more democratic environment? Imagine that you are working in a company with 10 people and you need 8 approvals in order to make a transaction. Using a software like Electrum you can simply create a custom multi-sig wallet with 10 keys. This way you can make seamless democratic transactions in your company. Even with all its amazing features, at the end of the day, a multi-signature wallet is still a hot wallet so you must use it economically.
The Bitfinex hack more on it in a bit happened despite the fact that it had multi-signature security. Plus, at the end of the day, the company whose wallet you are using still has one of the private keys. It completely depends on their ethics as to what they can do or not do to your funds.
Bitfinex made a partnership with BitGo in and created a system whereby multi-signature wallets, those where keys are divided among a number of owners to manage risk, would be provided to each customer. As discussed earlier, a multisignature wallet has keys divided among a number of owners to manage risk. In order for a transaction to go through, all parties need to sign off on it.
In the case of Bitfinex, 2 keys would be stored by them while one will be stored by BitGo. So, BitGo is supposed to act as an additional security and verify the validity of the transactions leaving Bitfinex. The idea was to increase the ease of liquidity without compromising on the security. There are a lot of theories as to why exactly that happened.
Theories that go from conspiratorial to downright ridiculous. They first issued a BFX token to all their customers, which was basically an IOU for all the funds that they owned them. However, rumors started circulating that this was just a scam from Bitfinex to buy more time to pay back the debt. On September 1, in order the allay the fears and doubts of the Bitcoin community, they bought back the first 1. But that was not the end of their efforts.
Bitfinex added more trading pairs, enabled faster withdrawals and created an OTC trading desk for larger trades and, eventually, business picked up enough to enable them to get out of debt faster.
While not technically a malicious hack, what has recently as of writing , happened with the parity multi-sig wallets deserves a mention. Before we continue, huge shoutout to SpringRole for all the data. On 20th of July, a new version of the Parity wallet contract was initiated because of a breach that happened before that.
