## Transaction Performance

With the upgrade to Heimdall v2, deterministic finality on Polygon Chain has
been reduced to 2-5 seconds, driven by the 1-2 second block time in Heimdall.

The [Rio upgrade](https://polygon.technology/blog/polygon-launches-major-payments-upgrade-with-rio-faster-lighter-and-easier-to-build)
further improves payment performance through the Validator-Elected Block Producer
(VEBloP) model. Key characteristics:

* **Near-instant finality**: Eliminates chain reorganizations (reorgs).
* **Ultra-low gas costs**: Maintained across the upgrade.
* **Up to 5,000 TPS** in the near term.
* **Stateless validation** (PIP-72): Nodes no longer need to store the full
  chain state, reducing hardware, storage, and sync time requirements.

## Network Uptime

Polygon maintains 99.999% network uptime. Current status is available at
[status.polygon.technology](https://status.polygon.technology/).
