Anyone who runs the Ethereum software on their computer is participating in the operations of this world-computer, the Ethereum Virtual Machine (EVM). To put it another way, Ethereum is literally a computer that spans the entire world. Ethereum’s corresponding digital currency, ether, is essentially a side effect of powering this massive computer. While Bitcoin uses its blockchain to implement a ledger of monetary transactions, Ethereum uses its blockchain to record state transitions in a gigantic distributed computer. But don’t be fooled: though it is a digital currency like Bitcoin, Ethereum is much more powerful. Like all cryptocurrencies, Ethereum is a descendant of the Bitcoin protocol, and improves on Bitcoin’s design. It has since grown to be the second largest digital currency in the world by market cap - $20 billion, compared to Bitcoin’s $40 billion.

There are three building blocks to this story: Ethereum, smart contracts, and digital wallets.Įthereum is a digital currency invented in 2013 - a full 4 years after the release of Bitcoin. If you are familiar with Ethereum and the crypto world, you can skip to the second section. What now? The attack’s implications about the future and security of smart contracts.How did they do it? A technical explanation of the attack (specifically for programmers).What exactly happened? An explanation of Ethereum, smart contracts, and multi-signature wallets.This is all pretty complicated, so to make the details of this clear for everyone, this post is broken into three parts:

Rather, it was a vulnerability in the default smart contract code that the Parity client gives the user for deploying multi-signature wallets. It’s important to understand that this exploit was not a vulnerability in Ethereum or in Parity itself. It’s an extraordinary story, and it has significant implications for the world of cryptocurrencies. The people who had their money saved by this heroic feat are now in the process of retrieving their funds. Once the money was safely stolen, they began the process of returning the funds to their respective account holders.
To prevent the hacker from robbing any more banks, the white-hats wrote software to rob all of the remaining banks in the world. Time was of the essence, so they saw only one available option: hack the remaining wallets before the attacker did.īy exploiting the same vulnerability, the white-hats hacked all of the remaining at-risk wallets and drained their accounts, effectively preventing the attacker from reaching any of the remaining $150,000,000. They analyzed the attack and realized that there was no way to reverse the thefts, yet many more wallets were vulnerable. Having sounded the alarm bells, a group of benevolent white-hat hackers from the Ethereum community rapidly organized. Given a couple more hours, the hacker could’ve made off with over $180,000,000 from vulnerable wallets. Yesterday, a hacker pulled off the second biggest heist in the history of digital currencies.Īround 12:00 PST, an unknown attacker exploited a critical flaw in the Parity multi-signature wallet on the Ethereum network, draining three massive wallets of over $31,000,000 worth of Ether in a matter of minutes.
