Hard Fork

A hard fork is a radical change to a blockchain protocol that makes previously invalid blocks or transactions valid, or vice-versa. This type of upgrade is not backward-compatible, meaning that all nodes must upgrade to the new version to continue participating in the network.

If some nodes do not upgrade, the network will split into two distinct chains, each following its own set of rules. Hard forks are typically used for major structural changes, such as modifying the consensus algorithm or addressing deep-seated protocol issues.

They require significant coordination among the community, developers, and node operators to avoid a permanent split. While they can lead to the creation of new assets or the abandonment of the old chain, they are often seen as a last resort due to the potential for community division.

For traders, hard forks can create uncertainty and market volatility as the value of the split assets is determined. They are the ultimate expression of democratic or contentious governance in a decentralized system.
