 #### Key Features
 
-- **Fully Decentralized**: Powered by 1,600+ independent worker nodes.
-- **12x Replication**: Redundant data storage for maximum reliability, capable of querying up to **20 million blocks per second**.
+- **Fully Decentralized**: Powered by 1,900+ independent worker nodes.
+- **High Replication**: Redundant data storage for maximum reliability, capable of querying up to **20 million blocks per second**.
 - **Improved Performance**: A new Rust-based query engine now leverages parallelized queries and incorporates numerous query execution performance optimizations, delivering an overall **10-50x performance boost** compared to the centralized gateways.
-  + Note that the performance improvement only affects data retrieval. If your application has another bottleneck (typically the database) you may only see a moderate gain in indexing speed.
+  + Note: This performance improvement is specific to data retrieval. If your application faces other bottlenecks (like database limitations), you may experience a more moderate gain in indexing speed.
 - **Real-time Capability**: Portal is now capable of streaming real-time data, including unfinalized blocks.

 ## What You Can Do
 
-### 1. Explore the Public Portal
+### 1. Explore Soldexer — Our New Brand for Solana
 
-Public Portal allows access to nearly all the datasets that were available from the centralized gateways. Use it for development and tests.
-
-Browse EVM and Substate datasets at [portal-ui.sqd.dev](https://portal-ui.sqd.dev/). Solana and [compatible SVM networks](/subsquid-network/reference/networks/#solana-and-compatibles) are also available. Real time data is only enabled for Solana Mainnet.
+If you’re working with Solana, visit [soldexer.dev](https://soldexer.dev) to check out our new client architecture, powered by the updated Portal API.
 
 ### 2. Migrate to the Cloud Portal
 
-If you're a Cloud user, consider switching from centralized gateways to the dedicated Cloud Portal.
-- Get the performance and other latest features of the new query engine.
+Cloud users can now switch from centralized gateways to our dedicated Cloud Portal and benefit from enhanced performance and the latest features of our new query engine.

   - [For Solana users](/cloud/resources/migrate-to-portal-on-solana)
 
-### 3. Check out Soldexer: SQD's spinoff in the Solana world
-
-If you are a Solana user, take a look at [soldexer.ai](https://soldexer.ai). The project features a new client architecture enabled by the updated Portal API.
