64-66: Improved consistency and clarity in Modules sectionThe standardization of "Proof-of-Stake" terminology and the rewording of the custom modules paragraph enhance the consistency and clarity of the document. These changes make the information more accessible to users.
Consider adding a brief example or link to documentation about creating custom modules to further assist users interested in extending the Cosmos SDK.

18-18: Improved clarity with concise analogyThe revised sentence effectively uses the Lego kit analogy to explain the SDK's flexibility. It's more concise and clearer than the previous version.
Consider adding a brief introductory phrase to smooth the transition:
-You can think of the SDK as a lego kit. You can choose to build the basic house from the instructions, or you can choose to modify your house and add more floors, more doors, more windows. The choice is yours. +To illustrate, you can think of the SDK as a Lego kit. You can choose to build the basic house from the instructions, or you can choose to modify your house and add more floors, more doors, more windows. The choice is yours.
30-30: Comprehensive explanation of modularity with minor grammatical suggestionThe paragraph effectively explains the concept of modularity in blockchain development and how the Cosmos SDK enables it. The examples provided are clear and relevant.
Add a comma after "For example" for better readability:
-Today, there is a lot of talk around modularity and discussions between monolithic and modular. Originally, the Cosmos SDK was built with a vision of modularity in mind. Modularity is derived from splitting a blockchain into customizable layers of execution, consensus, settlement and data availability, which is what the Cosmos SDK enables. This means that developers can plug and play, making their blockchain customizable by using different software for different layers. For example you can choose to build a vanilla chain and use the Cosmos SDK with CometBFT. CometBFT will be your consensus layer and the chain itself would be the settlement and execution layer. Another route could be to use the SDK with Rollkit and [Celestia](https://celestia.org/) as your consensus and data availability layer. The benefit of modularity is that you can customize your chain to your specific use case. +Today, there is a lot of talk around modularity and discussions between monolithic and modular.

36-37: Informative points with minor suggestions for improvementThese bullet points effectively highlight the flexibility and strength of the Cosmos SDK, particularly in terms of consensus layer customization and the use of CometBFT.
Consider the following minor improvements:
- Add a period at the end of the first bullet point for consistency.
- Rephrase the beginning of the second bullet point for clarity.
