# Optimism Bedrock

Bedrock, the first official release of the OP Stack, a collection of modular components that are freely available and open-source, serving as the backbone of Optimism.\
The [Optimism Bedrock documentation](https://community.optimism.io/docs/developers/bedrock/explainer/?ref=blog.synthetix.io#improved-node-performance) provide a concise overview of the notable enhancements offered by this release:

* ⛽️ **Reduced gas fees:** Bedrock uses an optimized data compression strategy, resulting in a substantial reduction in transaction costs. In addition, it eliminates all gas costs associated with EVM execution when submitting data to Layer 1 (L1), cutting fees by an extra 10%.\
  \
  With this upgrade, users can enjoy lower transaction costs, enabling a more cost-effective trading and improving the overall affordability of participating in the **Polynomial Trade ecosystem**.\
  \
  With lower transaction costs, the required deposit for keepers on Polynomial Trade will be reduced, making it one of the most cost-effective options available in the decentralized finance (DeFi) space.<br>
* **⚡️ Faster order confirmation:** this update has brought a significant improvement. Optimism's increased scalability and efficiency reduces order completion time on Polynomial Trade to less than 3 seconds. Before Bedrock, the average order completion time on the platform was around 13-15 seconds.

In the image above you can see the difference in costs before and after the Bedrock upgrade.

These improvements make Bedrock a significant step forward for Optimism and its ecosystem. Optimism is now: more affordable, faster, and more secure.
