## Synchronous Vs Asynchronous Consensus

The distinction between synchronous and asynchronous consensus models lies in the assumptions made about the timing of network communication. Synchronous models assume there is a known upper bound on the time it takes for messages to be delivered between nodes.

This simplifies consensus but can be fragile if network delays exceed expectations. Asynchronous models make no assumptions about message delivery times, prioritizing correctness over timing.

While more robust, asynchronous consensus is theoretically more complex to implement and often slower to achieve finality. Many modern blockchain protocols use semi-synchronous or partially synchronous models to balance these requirements.

Understanding these timing assumptions is essential for predicting how a network will behave under extreme stress or network instability.
