Hard Fork Risk

Definition

Hard fork risk refers to the potential for a significant, backward-incompatible upgrade to a blockchain protocol to result in a permanent split of the network into two distinct chains. This occurs when a new set of rules is introduced that older versions of the software cannot validate, requiring all participants to upgrade. If a substantial portion of the network does not adopt the new rules, two separate, incompatible blockchains may continue to operate. This division can lead to economic instability and network fragmentation.
