Dao hard fork ethereum
The initial premise of cryptocurrency was to disintermediate corporate institutions that control money issuance. It has since evolved to encompass blockchain technology that in turn has a host of applications. Most of these projects are run by a decentralized autonomous organization DAO. They replace humans with code that acts similarly to a venture capital fund by allocating resources as it sees fit. Early DAOs in the s faced criticism due to widespread security concerns. Ethereum expanded upon these capabilities by building a smart contract network that lets anyone build their own DAO on top.

Vitalik Buterin About the Attack On The Dao. What Did Ethereum Experience Then?
Imagine that tomorrow you wake up and discover that you've been taken for all you're worth by an anonymous hacker. You have a month to decide what to do.
This might seem like an impossible situation, the kind of pressure cooker that breeds hasty decisions, but it's exactly the dilemma that faced the developers and users of a new cryptocurrency and coding platform called Ethereum. In June, millions of dollars were stolen from a crowd-directed investment fund called the DAO and siphoned into a smaller version referred to as a "child DAO.
This meant a change to Ethereum's code that split the currency into two versions , which users had to choose between by either updating their software or not. It was a risky proposal that threatened to permanently cleave Ethereum, and it had its share of vocal dissenters who saw the change as manipulating the system to " bail out " the DAO. Mere hours after the fork began, however, Ethereum creator Vitalik Buterin called it : the fork was a success, with 85 percent of users moving over to the new version.
Users of Bitcoin, the cryptocurrency that inspired large portions of how Ethereum works, were watching the fork closely and tweeting with a heady mix of respect for the Ethereum community and perhaps just a bit of jealousy. You see, Bitcoin has been gripped with indecision amid a year-long debate over whether or not to fork the currency's software just like Ethereum did.
How did Ethereum manage to do in a month what Bitcoin seems utterly incapable of even coming close to pulling off?
The main factors may be Ethereum's relatively small community compared to Bitcoin, making it easier to come to a consensus, and how hard forks are built into the platform in a way that Bitcoin has never seen. While hate may be a strong word, the debate about whether to hard fork Bitcoin's software has reached critical levels of acrimony and ideological rhetoric about the virtues of decentralization.
The furor led core developer Mike Hearn to slam the door on Bitcoin and brand the whole experiment a failure. The bitcoin ecosystem is also extremely varied and everybody is trying to protect their interests without blowing the whole thing up, from the miners who make thousands of dollars for every block of bitcoin data they compute to the services that allow people to send money overseas or buy groceries with bitcoin.
The system is entrenched, and changing anything at all elicits fears of a shake-up. Who would volunteer? In contrast, Ethereum is still a very young platform with only a few thousand users and one killer app: the DAO. Forking the system to save the one thing that Ethereum really had going for it, and that many people had invested in, was a no-brainer for most and easy to agree upon.
In contrast, changes to Bitcoin are likely to advantage one group while having potentially dire economic consequences for many others. Vitalik Buterin, the inventor of Ethereum, agreed that the largest difference between bitcoin and Ethereum when it comes to forking is "the differences between the two protocols' communities. However, he also suggested after the hard fork on Wednesday that if Ethereum ever needs to fork again in order to solve a major problem, it may not be so easy.
The second reason for Ethereum's apparent ease in pulling off a hard fork compared to bitcoin, Tual said, is that hard forks are par for the course at this nascent stage of the platform's development. The hard fork to refund the DAO's money was actually Ethereum's third—there's been one every time the software has been upgraded to a more powerful version—and there is even one on the horizon, since Ethereum is getting set to upgrade to a version called Metropolis.
In contrast, Bitcoin has only ever experienced one event that could be described as a hard fork, and it was basically an accident that occurred not because of a planned software upgrade, but a faulty block of bitcoin data. Ethereum is still a big experiment that can afford to have a few eggs broken at the moment, Tual said. The deadlock between competing corners of the Bitcoin community when it comes to hard forking, in contrast, spells doom for the currency, according to Tual.
According to Biggs, Bitcoin's failure to evolve thanks to an inability to agree on a way forward means that centralized organizations—say, banks or credit payment processing companies— will be the ones to benefit from the technology simply because they're able to move faster when it comes to changing the system.
For Ethereum, riding on the high of a successful fork, a similar fate might seem like a distant possibility right now—but proponents of the platform would do well to heed Buterin's warning and wonder: for how long?

Ether Explained – Chapter 4: The Decentralized Autonomous Organisaion (DAO)
After the embarrassing failure of the DAO in , the Ethereum Foundation moved quickly to address the problem by implementing a hard fork. That DAO hard fork was not popular, but it was effective. The majority of miners moved over to the new chain, and the DAO funds went into a new smart contract, so the original investors could safely withdraw their funds. To be clear, the Ethereum network itself was not hacked, just the DAO smart contract. The hacker took advantage of a loophole in the contract code, written in the JavaScript-like language Solidity. But while the hard fork was an expedient solution to a pressing problem, how the decision-making was handled has long-term consequences for Ethereum.
The DAO hack in eight minutes
A hard fork or hardfork , as it relates to blockchain technology, is a radical change to a network's protocol that makes previously invalid blocks and transactions valid, or vice-versa. A hard fork requires all nodes or users to upgrade to the latest version of the protocol software. Forks may be initiated by developers or members of a crypto community who grow dissatisfied with functionalities offered by existing blockchain implementations. They may also emerge as a way to crowdsource funding for new technology projects or cryptocurrency offerings. A hard fork can be contrasted with a soft fork. A hard fork is when nodes of the newest version of a blockchain no longer accept the older version s of the blockchain; which creates a permanent divergence from the previous version of the blockchain. Adding a new rule to the code essentially creates a fork in the blockchain: one path follows the new, upgraded blockchain, and the other path continues along the old path. Generally, after a short time, those on the old chain will realize that their version of the blockchain is outdated or irrelevant and quickly upgrade to the latest version. A fork in a blockchain can occur in any crypto-technology platform—not only Bitcoin. That is because blockchains and cryptocurrency work in basically the same way no matter which crypto platform they're on.

Changes to the rules of the Ethereum protocol which often include planned technical upgrades. Forks are when major technical upgrades or changes need to be made to the network — they typically stem from Ethereum Improvement Proposals EIPs and change the "rules" of the protocol.

The DAO: the steadfast iron will of unstoppable code
DAO in general stands for Decentralized Autonomous Organization and represents a smart contract that governs the operations of an organization. Created by the team behind German startup Slock. The huge popularity of The DAO attracted security researchers and hackers alike, and on May 27, the first security analysis of The DAO code surfaced in the public sphere. Below is a short summary of the 7 attack vectors presented in the paper, resulting from a poor mechanism design of The DAO and its voting system, some of which could cause honest investors to lose investment capital:. Unfortunately, the report came too late and The DAO launched the following day, on May 28th, with its tokens trading on the biggest exchanges like Poloniex and Kraken. I still think that splitDAO may have a vulnerability. It violates the withdraw pattern by not zeroing the balances[] field until after the call.
Remember me Lost your password? The move is an important vote of confidence for the democratic system that is used to reach consensus in blockchain-based systems. A fork — or change to the software that governs the blockchain — would be the only way to recover these funds from an otherwise anonymous attacker.
The much anticipated hard fork of the ethereum blockchain has been implemented, giving those building on the decentralized application network at least the potential for stability after weeks of controversy and sometimes terse disagreements in the wider community. Seconds later the mining pool also mined the first block on the new blockchain, which returned funds lost in the collapse of The DAO to an account available to its original investors. However, the actual implications of the decision, which essentially showed that a supposedly immutable blockchain history can be altered, is yet to be seen. Co-founder of ethereum startup Slock.
Ethereum is a blockchain that was launched in July of Vitalik Buterin, a former Bitcoin miner who saw new potential in blockchain technology, is the creator of Ethereum. The Ethereum blockchain also houses a cryptocurrency called Ether. Ethereum got in the public eye for all the wrong reasons with its involvement in the DAO. It may not seem like it, but not all blockchains are created equal. Ethereum utilizes smart contracts to create automated transactions over its blockchain.
Picture this: A thief steals millions of dollars by hacking into an investment fund. What if you could just hit the undo button and get that money back? That was the dilemma that the creators of Ethereum, an upstart digital currency platform, recently faced. Founded in by a group of researchers led by Russian-Canadian Vitalik Buterin — then only 19 years old — its currency, ether, is the second-most valuable digital currency after bitcoin.
In my opinion it is obvious. I recommend to you to look in google.com
