As the graphic below displays, nodes that are not upgraded reject the new rules, which creates a divergence, or hard fork, in the blockchain. There are a number of reasons why developers may implement a hard fork, such as correcting important security risks found in older versions of the software, to add new functionality, or to reverse transactions—as when the Ethereum blockchain created a hard fork to reverse the hack on the Decentralized Autonomous Organization DAO.
Rather, it relocated the funds tied to the DAO to a newly created smart contract with the single purpose of letting the original owners withdraw their funds.
The extra balance of tokens and any ether that remains as a result of the hard fork will be withdrawn and distributed by the DAO curators to provide "failsafe protection" for the organization. Whereas with a hard fork, both the old and new blockchains exist side by side, which means that the software must be updated to work by the new rules. Both forks create a split, but a hard fork creates two blockchains and a soft fork is meant to result in one.
Considering the differences in security between hard and soft forks, almost all users and developers call for a hard fork, even when a soft fork seems like it could do the job. Overhauling the blocks in a blockchain requires a tremendous amount of computing power, but the privacy gained from a hard fork makes more sense than using a soft fork.
