Backward Compatibility

Backward compatibility is the ability of a new software version to process data or transactions created by older versions of the same system. In cryptocurrency protocols, this is the hallmark of a soft fork, allowing the network to upgrade features without forcing every user to update their client immediately.

It ensures that the ecosystem remains inclusive and reduces the risk of community splits. Without backward compatibility, upgrades become mandatory and potentially divisive.

This design choice is critical for maintaining long-term network effects. It balances the need for innovation with the necessity of operational continuity.
