## Schema Evolution

Schema evolution refers to the ability of a data serialization system to handle changes in the structure of data over time without breaking existing applications. In the fast-moving world of cryptocurrency, protocols frequently update their data models to include new transaction types or improved metadata.

Schema evolution allows older systems to continue reading data from newer systems, and vice versa, by ignoring unknown fields or using default values for missing ones. This is vital for maintaining uptime in distributed financial networks where upgrading every node simultaneously is impossible.

Without robust schema evolution, a simple update to a trade message format could lead to a total network partition or a catastrophic failure of derivative clearing mechanisms. It ensures that the protocol remains resilient and adaptable as the market environment changes.
