A hard fork is a permanent change to the underlying protocol of a blockchain network. A hard fork effectively creates a new version of the blockchain with different rules from the old version.
A hard fork can be used to upgrade a blockchain network, or to create a new blockchain entirely.
The Ethereum hard fork was a necessary change to the Ethereum protocol in order to enable new features and improve scalability. The hard fork occurred on October 25, 2017 and resulted in two separate blockchain networks: Ethereum (ETH) and Ethereum Classic (ETC).
ETH is the new version of the Ethereum blockchain, while ETC is the old version.
The hard fork was controversial and resulted in much debate within the Ethereum community. Some members of the community believed that the hard fork should not have been implemented, and that Ethereum should have remained true to its decentralized roots.
NOTE: WARNING: Ethereum Hard Forks involve a risk of financial loss. Before participating in any Ethereum Hard Fork, please be sure to understand the risks associated with these events, including but not limited to potential loss of funds, price volatility, and technical difficulty. As with all cryptocurrency investments, please do your own research prior to making any decisions.
However, others believed that the hard fork was necessary in order to enable Ethereum to scale and meet growing demand.
The debate over whether or not to hard fork Ethereum highlights the importance of decentralization in cryptocurrency. Decentralization means that no single entity has control over the network.
This is opposed to centralization, where one entity has control. Cryptocurrencies are often touted as being more decentralized than traditional fiat currencies, which are controlled by central banks.
The Ethereum hard fork was a necessary change that improved scalability and enabled new features. However, it was also controversial and resulted in much debate within the community.
The debate highlights the importance of decentralization in cryptocurrency and underscores the need for discussion and consensus when making changes to a blockchain network.

A hard fork is a radical change to the protocol of a blockchain network that makes previously invalid blocks/transactions valid (or vice-versa). This requires all nodes or users to upgrade to the new rules in order to remain compatible with the network. Put simply, a hard fork is a permanent divergence from the previous version of the blockchain, and nodes running previous versions will no longer be accepted by the newest version.
A hard fork is a radical change to the protocol of a blockchain network that makes previously invalid blocks/transactions valid (or vice-versa). This requires all nodes or users to upgrade to the new version of the protocol software. Put simply, a hard fork is a software upgrade that is not backwards compatible.
On January 8, 2018, the Ethereum network experienced a hard fork that resulted in the creation of a new blockchain and cryptocurrency called Ethereum Classic (ETC). The hard fork was the result of a disagreement among the Ethereum community over how to best handle the DAO hack. The DAO was a Decentralized Autonomous Organization built on the Ethereum blockchain that raised over $150 million in crowdfunding before it was hacked in June 2016.
