SummaryThe DAO was a decentralized autonomous organization (DAO) that was launched in năm 2016 on the Ethereum blockchain. After raising $150 million USD worth of ether (ETH) through a token sale, The DAO was hacked due to lớn vulnerabilities in its code base. The Ethereum blockchain was eventually hard forked to lớn restore the stolen funds, but not all parties agreed with this decision, which resulted in the network splitting into two distinct blockchains: Ethereum and Ethereum Classic.

Origins of The DAO

Launched in 2016, The DAO was an early decentralized autonomous organization (DAO) intended to lớn act as an investor-directed venture capital firm. Lauded as a revolutionary project, The DAO raised $150 million USD worth of ether (ETH) and was one of the earliest crowdfunding efforts và high-profile projects built on the Ethereum blockchain — which at the time was only one year old. Less than three months after its launch, The DAO was hacked & $60 million of ether was stolen. The Ethereum blockchain, on which The DAO was built, was later controversially forked to restore the stolen funds, which were returned to lớn investors.

What Is a DAO?

A decentralized autonomous organization is a blockchain-based cooperative that is collectively owned by its members, with rules set và executed through code. DAOs replace centralized management structures with a techno-democratic approach wherein decisions are voted upon by investor-stakeholders. DAOs are built on vị trí cao nhất of blockchains (often Ethereum) & their transactions are visible on the underlying blockchain protocol. While The DAO was an early iteration of DAO governance, decentralized autonomous models remain highly influential in blockchain-related use, particularly amongst decentralized finance (DeFi) platforms.

After Ethereum protocol engineer Christoph Jentzsch released xuất hiện source code for a collectivized, ETH-based investment organization, The DAO launched on April 30, 2016, with a token sale that distributed DAO tokens in exchange for ETH. These DAO tokens were designed to facilitate voting on the allocation of The DAO’s collectivized funds to lớn entities, businesses, & technologies seeking investment. After approving funding proposals, stakeholders were meant lớn be in position lớn profit from their investments by reaping dividends or benefiting from a token price increased by representation in ownership of successful companies.

The DAO Hack

The token sale was set khổng lồ last 28 days, during which the tokens were “locked up,” & after which the DAO would begin to operate. By three weeks into the token sale, The DAO had raised more than $150 million from more than 11,000 investors, making it one of the largest crowdfunding campaigns in history at the time. However, even before the token sale had concluded, several onlookers expressed concerns about vulnerabilities in The DAO’s code. More specifically, computer scientists were concerned that a bug in The DAO’s wallet smart contracts would allow them to lớn be drained. While programmers attempted to lớn fix the bug, an attacker exploited the vulnerability and began siphoning funds from The DAO.

In the meantime, the Ethereum community debated how khổng lồ respond to lớn the attack. The DAO’s failure would not only mean financial loss for investors, but it also bore dire repercussions for the nascent Ethereum network. The DAO had become such a heavily invested project that its contracts contained approximately 14% of all ether (ETH) in circulation at the time. At only one year old, the promising Ethereum technology and community was faced with a genuine existential threat.

The Response lớn The DAO Hack

Initially, Ethereum founder Vitalik Buterin proposed a soft fork of the Ethereum network, adding a snippet of code that would effectively blacklist the attacker and prevent them from moving the stolen funds. However, shortly thereafter, the attacker — or someone posing as the attacker; it has not been verified — published an xuất hiện letter khổng lồ the Ethereum community claiming that the funds had been obtained in a “legal” way in accordance with the rules mix out in the smart contract. The attacker also said they would take legal kích hoạt against anyone who attempted to seize the ether.

Shortly after, tensions were heightened yet again when the alleged attacker (or someone posing as them) claimed through an intermediary on The DAO Slack channel that they would attempt to lớn thwart any soft fork by bribing Ethereum miners not to lớn comply. The bribe comprised a collective reward of one million ether và 100 bitcoin, & it split the Ethereum network in two. The situation not only presented technical challenges, but questioned the moral & philosophical underpinnings of the công nghệ — & the resilience of the Ethereum project’s leadership.

Before the Ethereum community could proceed with the soft fork, a bug was discovered in the update’s code, making it vulnerable lớn attack. A second solution — a hard fork — was proposed và eventually executed after much debate. The hard fork effectively rolled back the Ethereum network’s history to before The DAO attack & reallocated The DAO’s ether khổng lồ a different smart contract so that investors could withdraw their funds. This was extremely controversial — after all, blockchains are supposed to lớn be immutable và censorship-resistant.

It was initially unclear as to lớn whether the fork would be executed. Though it was proposed by Ethereum developers, they did not have the unilateral power lớn implement the change. Miners, exchanges, & node operators also had to lớn agree to update their software. After more heated debate in public forums, on July 20, 2016, at block 192,000, the Ethereum hard fork was implemented.

The DAO hack Remedy Forks Ethereum

While the vast majority of stakeholders adopted the change & the fork was implemented, not everyone was on board. As a result, the hard fork resulted in two competing — & now separate — Ethereum blockchains. Those who refused khổng lồ accept the hard fork that rolled back the blockchain’s history supported the pre-forked version — now known as Ethereum Classic (ETC). The blockchain presently known as Ethereum is the blockchain that implemented the hard fork & altered the blockchain’s history — và the history of blockchain as a whole.

Though the funds stolen from The DAO were restored to its investors, the attacker did not thua thảm out entirely. The pilfered tokens still remained in their possession on the Ethereum Classic chain and were worth around $8.5 million in ETC in the months following the attack.

The DAO hack & subsequent Ethereum hard fork shook the Ethereum community to lớn its core & highlighted major questions about the emerging technology. In retrospect, it’s clear that the decisions made by Vitalik Buterin, Etheruem developers, and the global community ensured the survival of the blockchain in its earliest days. Since The DAO hack, Ethereum has gone on khổng lồ become an essential pillar of blockchain, cryptocurrency, and decentralized finance.
