Conversation
📝 Walkthrough📝 WalkthroughWalkthroughThe changes introduce a new document titled "ADR 75: V2 Upgrades," which outlines a comprehensive rewrite of the Cosmos SDK architecture. This version, V2, aims to enhance modularity, extensibility, and performance by breaking down the monolithic structure into smaller, more manageable components. The document details the migration path from V1 to V2 and includes high-level diagrams of the new architecture, including the Consensus and State Transition Function components. Changes

13-15: Minor grammatical improvement suggested in the abstract.The abstract provides a concise overview of the V2 upgrades. Consider the following minor grammatical improvement:
-V2 is a reset in the Cosmos SDK architecture. It is a complete rewrite of the SDK, with a focus on modularity, extensibility, and performance. The V2 SDK breaks apart the core SDK into smaller modular components allowing users to pick and choose the components they need for their specific use case. This document outlines the changes and migration path for users of the V1 SDK. +V2 is a reset in the Cosmos SDK architecture. It is a complete rewrite of the SDK, with a focus on modularity, extensibility, and performance. The V2 SDK breaks apart the core SDK into smaller modular components, allowing users to select the components they need for their specific use case. This document outlines the changes and migration path for users of the V1 SDK.This change improves readability and adheres to standard English grammar rules.

This has led baseapp to be a very large monolith. +This is a high-level overview of Baseapp today.

-The Descision is to rewrite the core componenets (baseapp, server, store) of the SDK into smaller modules. +The Decision is to rewrite the core components (baseapp, server, store) of the SDK into smaller modules.This correction improves the professionalism of the document.
88-89: Correct typo and improve clarity in the runtime/v2 description.There's a typo and the sentence could be clearer. Consider the following change:
-In the above diagram we do not mention runtime/v2 because it is the componend that is responsible for combining all the other components into a single application. +In the above diagram, we do not mention runtime/v2 because it is the component responsible for combining all the other components into a single application.This change improves readability and corrects the spelling error.
92-93: Improve clarity in the Consensus component description.The description of the Consensus component could be clearer. Consider the following change:
-Consensus is the component that handles communication to the Consensus Engine (Networking & Consensus). The default implementation will be CometBFT, but other consensus engines can be used with v2. The goal of consensus is not to offer a consensus API to meet all needs, but a way to allow developers to swap out the server for a different consensus engine. An application developer should not assume that the cometbftserver will work with other consensus engines. +Consensus is the component that handles communication with the Consensus Engine (Networking & Consensus). The default implementation will be CometBFT, but other consensus engines can be used with v2. The goal of the Consensus component is not to offer a universal consensus API, but to provide a way for developers to swap out the server for a different consensus engine. Application developers should not assume that the CometBFT server will work with other consensus engines.These changes improve clarity and consistency in terminology.
164-196: Improve formatting and add comments to the Go interface.The Go interface for the State Transition Function could benefit from better formatting and comments. Consider the following changes:
type StateTransitionFunction[T transaction.Tx] interface { // DeliverBlock executes a block of transactions. DeliverBlock( ctx context.Context, block *server.BlockRequest[T], state store.ReaderMap, - ) (blockResult *server.BlockResponse, newState store.WriterMap, err error) + ) (*server.BlockResponse, store.WriterMap, error) // ValidateTx validates a transaction. ValidateTx( ctx context.Context, state store.ReaderMap, gasLimit uint64, tx T, ) server.TxResult // Simulate executes a transaction in simulation mode. Simulate( ctx context.Context, state store.ReaderMap, gasLimit uint64, tx T, - ) (server.TxResult, store.WriterMap) + ) (txResult server.TxResult, newState store.WriterMap) // Query executes a query on the application. Query( ctx context.Context, state store.ReaderMap, gasLimit uint64, req transaction.Msg, - ) (transaction.Msg, error) + ) (response transaction.Msg, err error) }These changes improve readability and follow Go best practices for interface definitions.
207-208: Improve clarity in the backwards compatibility explanation.The explanation of backwards compatibility could be clearer. Consider the following changes:
-The state machine was made to not affect modules that are not using the state transition function. If a user would like to migrate to v2 they will need to migrate to `appmodule.Environment` from `sdk.Context`. `sdk.Context` is a struct which is a global in the state machine, this desing limits the concurrency. +The state machine was designed to not affect modules that are not using the state transition function.

209-210: Clarify the breaking changes in CometBFT interaction.The description of breaking changes could be more precise. Consider the following changes:
-V2 will have a breaking changes in regards to how CometBFT handles certain fields in ABCI. Previously, the Cosmos SDK paniced and recovered in the case of out of gas, providing an error to CometBFT which we do not return in the new design. +V2 introduces breaking changes in how CometBFT handles certain fields in ABCI.

227-230: Consider expanding the further discussions section.The further discussions section is quite brief and could benefit from more context. Consider expanding this section to provide more details on:
- The potential benefits of rewriting the core in Rust.
- What "crosslang" refers to and its significance.
- Any other potential future developments or areas of research.
This expansion would give readers a better understanding of the long-term vision for the Cosmos SDK beyond the V2 upgrades.
231-233: Add relevant references to the document.The references section currently contains only a placeholder. To enhance the document's credibility and provide readers with additional resources, consider adding relevant references. These could include:
- Links to related Cosmos SDK documentation
- Academic papers or articles that influenced the V2 design decisions

1-234: Overall document review: Comprehensive but needs minor refinementsThis ADR provides a thorough overview of the V2 upgrades for Cosmos SDK. The document is well-structured and informative, covering key aspects such as context, decision rationale, architectural changes, and consequences.
However, there are several areas that could benefit from improvement:
- Minor grammatical and typographical errors throughout the document.
- Some sections, particularly Alternatives and Further Discussions, could be expanded for more comprehensive coverage.
- Consistency in terminology and capitalization (e.g., "baseapp" vs "Baseapp").
Recommendation:
- Conduct a thorough proofreading of the entire document to address grammatical and typographical issues.
- Consider expanding the Alternatives and Further Discussions sections as suggested in previous comments.
- Ensure consistency in terminology and capitalization throughout the document.
- Review the mermaid diagrams to ensure they accurately represent the latest architectural decisions.

| The state machine was made to not affect modules that are not using the state transition function. If a user would like to migrate to v2 they will need to migrate to `appmodule.Environment` from `sdk.Context`. `sdk.Context` is a struct which is a global in the state machine, this desing limits the concurrency. | ||
