State Consistency Guarantees

For high performance blockchains, the latency between events being emitted and state updates can cause strange behaviors without Somnia Reactivity

Somnia ensures notifications deliver events and state that are consistent—sourced from the exact same block. This eliminates race conditions common in pull models.

How It Works

• Atomic Delivery: Event + state (via ETH calls) processed in one validator-executed bundle.

• Guarantees:

  • Non-coalesced: One notification per event.

  • Coalesced: Batched, but state reflects the latest in the batch.

Example Impact

In a DeFi app, a "Transfer" event pushes the new balance immediately—no extra balanceOf call needed.

This makes dApps more reliable and easier to reason about.
