Update CiphernodeAdded event to utilize the Address type for data.address.

The CiphernodeAdded event currently uses data.address as a string. To enhance type safety and maintain consistency, consider updating it to use the Address type.

  • File: packages/ciphernode/core/src/logger.rs
    • Ensure data.address is of type Address instead of String.
Analysis chain

Line range hint 52-54: Consider potential future changes to CiphernodeAdded event handling.

The CiphernodeAdded event handling currently uses data.address as a string. Given the new Address import and the PR objectives, you might consider updating this to use the Address type in the future.

To ensure consistency across the codebase:

  1. Are there plans to update the CiphernodeAdded event to use the Address type?
  2. Are similar changes being made in other files where address is used?

You can run this script to check for address usage in other files:

Length of output: 101

packages/ciphernode/core/src/ciphernode_selector.rs (2)

10-10: Approved: Address type change aligns with PR objectives.

The change from Address to String for the address field aligns with the goal of excluding alloy types from the domain. This provides more flexibility in handling addresses.

Consider introducing a type alias for the address string to improve code readability and maintainability:

type AddressString = String;

pub struct CiphernodeSelector {
    // ...
    address: AddressString,
}

This would make it easier to change the underlying type in the future if needed.


18-22: Approved: Constructor updated to match new address type.

The new method has been correctly updated to accept a &str instead of Address, maintaining consistency with the struct field change. The use of to_owned() ensures proper ownership of the string.

Consider using String::from(address) instead of address.to_owned() for slightly better readability:

address: String::from(address),

Both methods have the same effect, but String::from might be more idiomatic in this context.

packages/ciphernode/core/src/main_ciphernode.rs (1)

66-66: LGTM: Consistent address conversion to string

The conversion of address to a string before passing it to CiphernodeFactory::create is consistent with the previous change for CiphernodeSelector. This maintains consistency in how addresses are handled.

Consider refactoring to reduce duplication:

-    let selector =
-        CiphernodeSelector::attach(bus.clone(), sortition.clone(), &address.to_string());
+    let address_str = address.to_string();
+    let selector =
+        CiphernodeSelector::attach(bus.clone(), sortition.clone(), &address_str);

     // ... other code ...

     .add_hook(CiphernodeFactory::create(
         bus.clone(),
         data.clone(),
-        &address.to_string(),
+        &address_str,
     ))

This refactoring would reduce the number of times to_string() is called on address and make the code more maintainable.

packages/ciphernode/core/src/sortition.rs (1)

40-61: Approve changes with suggestions for improvement.

The changes to the SortitionList trait implementation for SortitionModule are consistent with the overall refactoring from Address to String. However, there are a few points to consider:

  1. In the contains method, the parsing of String to Address (line 47) could potentially fail. Consider adding error handling to manage this scenario.

  2. The comparison in the contains method (line 53) uses to_string(), which might be less efficient than comparing addresses directly. Consider using a more efficient comparison method if possible.

Consider applying the following improvements:

  1. Add error handling for address parsing:
.map(|b| b.parse().unwrap_or_else(|_| panic!("Invalid address format")))
  1. If possible, implement a more efficient comparison method:
.any(|(_, addr)| addr == &address.parse().unwrap_or_else(|_| panic!("Invalid address format")))

These changes will improve error handling and potentially increase performance.

packages/ciphernode/core/src/e3_request.rs (2)

Line range hint 131-146: Consider enhancing error handling and logging in the handle method

The handle method in E3RequestManager plays a crucial role in processing EnclaveEvent messages. To improve robustness and debuggability, consider the following enhancements:

  1. Add logging for events that don't have an e3_id, which are currently silently ignored.
  2. Consider using tracing or a similar logging framework for structured logging throughout the method.
  3. Implement error handling for the factory calls, which might fail in unexpected ways.

These improvements would align well with the PR objectives by ensuring more reliable EVM event handling and easier debugging.


Line range hint 1-146: Summary: File aligns with PR objectives, with room for future enhancements

This file plays a crucial role in managing E3 requests and events, which aligns well with the PR objectives of EVM integration. The main change (adding #[derive(Default)] to EventBuffer) is a valid improvement that simplifies the code.

For future enhancements, consider:

  1. Implementing the suggested Typestate pattern mentioned in the TODO comments.
  2. Enhancing error handling and logging throughout the file, especially in the E3RequestManager::handle method.
  3. Adding more comprehensive documentation to explain how this file interacts with the broader EVM integration process.

These improvements would further strengthen the EVM integration and make the codebase more robust and maintainable.

packages/ciphernode/enclave_node/src/bin/cmd.rs (2)

51-51: LGTM: Address conversion to string.

The change from address: ADDRS[0] to address: ADDRS[0].to_string() aligns with the PR objectives of replacing the Address type with String. This ensures that the address is correctly formatted as a string when dispatched in the EnclaveEvent.

For consistency and to avoid repetition, consider creating a helper function to handle the registration process:

fn register_ciphernode(bus: &Addr<EventBus>, addr: Address, index: usize, num_nodes: usize) {
    println!("Registering Ciphernode {}", addr);
    bus.do_send(EnclaveEvent::from(CiphernodeAdded {
        address: addr.to_string(),
        index,
        num_nodes,
    }));
}

Then, you can use it like this:

["reg", "1"] => register_ciphernode(&bus, ADDRS[0], 0, 1),
["reg", "2"] => register_ciphernode(&bus, ADDRS[1], 1, 2),
// ... and so on

This refactoring would make the code more maintainable and reduce the risk of inconsistencies between similar blocks.


Line range hint 1-114: Overall assessment: Changes align well with PR objectives.

The modifications in this file consistently implement the following changes:

  1. Conversion of Address to String in CiphernodeAdded events.
  2. Update of the committee request event from CommitteeRequested to E3Requested.
  3. Renaming and restructuring of parameters in the E3Requested event.

These changes align well with the PR objectives and the AI-generated summary. The code maintains consistency across similar operations, but there's room for further refactoring to improve maintainability.

Key points to consider:

  1. Implement the suggested helper function for ciphernode registration to reduce code duplication.
  2. Run the provided verification script to ensure consistency across the codebase.
  3. Consider adding comments to explain the significance of the new parameters (e.g., threshold_m) for better code documentation.

As the codebase evolves, consider creating a dedicated module for event handling and dispatching. This would centralize event-related logic and make it easier to maintain and extend in the future.

packages/ciphernode/core/src/ciphernode.rs (3)

24-29: LGTM: Constructor update is consistent with the struct change.

The new method signature change to accept &str and the use of to_string() are consistent with the address field type change. This provides more flexibility for the caller.

Consider using String::from(address) instead of address.to_string() for a slight performance improvement:

-    address:address.to_string(),
+    address: String::from(address),

This avoids an unnecessary allocation when the input is already a String.


Line range hint 153-166: LGTM: CiphernodeFactory::create method updated correctly.

The changes in the CiphernodeFactory::create method are consistent with the previous modifications. The method now accepts a &str, converts it to a String, and correctly passes it to Ciphernode::new.

Consider using String::from(address) instead of address.to_string() for a slight performance improvement:

-    let address = address.to_string();
+    let address = String::from(address);

This avoids an unnecessary allocation when the input is already a String.


Line range hint 1-169: Summary: Address type change successfully implemented.

The changes in this file consistently replace the Address type with String for the address field and related method parameters. This modification aligns with the PR objectives of integrating EVM functionality and makes the code more flexible and easier to work with in Rust.

Key points:

  1. The Ciphernode struct and its methods have been updated to use String for addresses.
  2. Handler implementations and async functions have been adjusted to work with the new String type.
  3. The CiphernodeFactory::create method has been updated to accept a &str and convert it to a String.

These changes should improve the integration with EVM events and simplify the handling of addresses throughout the codebase.

To further improve the code:

  1. Consider creating a type alias for Address (e.g., type Address = String;) to maintain semantic meaning while keeping the flexibility of String.
  2. If Address was previously a custom type with additional functionality, consider implementing those functions as extension traits on String to maintain any domain-specific behavior.
  3. Ensure that all parts of the codebase that interact with addresses are updated to use the new String representation consistently.
packages/ciphernode/core/src/plaintext_aggregator.rs (4)

11-11: Approve change with minor suggestion

The replacement of nodecount: usize with threshold_m: u32 is appropriate and aligns with the PR objectives. The new name better reflects its purpose in threshold cryptography.

Consider adding a comment explaining the meaning of 'm' in threshold_m for clarity, e.g.:

/// The threshold 'm' represents the minimum number of shares required for reconstruction
threshold_m: u32,

62-64: Approve changes with optimization suggestion

The modifications in the add_share method correctly update the logic to use the new threshold_m field, aligning with the PR objectives. The cast to usize in the comparison is necessary and correct.

Consider caching the threshold_m as usize value to avoid repeated casts:

let threshold: usize = *threshold_m as usize;
if shares.len() == threshold {
    // ...
}

This minor optimization could be beneficial if add_share is called frequently.

Also applies to: 71-71


109-109: Approve changes with consistency suggestion

The modifications in the Handler<DecryptionshareCreated> implementation correctly update the event handling logic to use the new threshold_m field. This aligns with the PR objectives of converting and handling EVM events appropriately.

For consistency with the earlier suggestion, consider caching the threshold_m as usize value:

let threshold: usize = threshold_m as usize;
let size = threshold;

This change would make the code more consistent with the suggested optimization in the add_share method.

Also applies to: 116-116


Line range hint 1-208: Summary of PlaintextAggregator changes

The modifications in this file successfully implement the transition from a node count-based system to a threshold-based system for plaintext aggregation. These changes align well with the PR objectives of integrating EVM functionality and handling related events.

Key points:

  1. Consistent replacement of nodecount with threshold_m throughout the file.
  2. Appropriate type changes from usize to u32 for the threshold.
  3. Updated logic in add_share and event handling to use the new threshold-based approach.
  4. Factory method updated to use the new threshold metadata.

The changes improve the clarity and correctness of the plaintext aggregation process in the context of threshold cryptography. The suggested minor optimizations and consistency improvements, if implemented, would further enhance the code quality.

Consider documenting the rationale behind the transition from node count to threshold-based logic in a comment at the top of the file or in the module documentation. This would provide valuable context for future maintainers and ensure that the design decision is well-understood.

packages/ciphernode/core/src/fhe.rs (1)

193-196: LGTM: Event handling updated as per PR objectives.

The change from EnclaveEvent::CommitteeRequested to EnclaveEvent::E3Requested aligns with the PR objective of synchronizing EVM events with contract events. The necessary parameters are still being extracted correctly from the new event type.

Consider adding an error log or handling for the case when the event is not E3Requested. This would improve debugging and error tracing:

let EnclaveEvent::E3Requested { data, .. } = evt else {
    log::warn!("Unexpected event type in FheFactory::create: {:?}", evt);
    return;
};
packages/ciphernode/core/src/lib.rs (4)

128-129: LGTM: eth_addrs type change, with a suggestion

The change from Vec<Address> to Vec<String> aligns with the objective of moving away from alloy types. The conversion to strings is correctly implemented.

Consider creating a helper function for generating random Ethereum addresses as strings to improve readability and reusability:

fn generate_random_eth_address() -> String {
    Address::from_slice(&rand::thread_rng().gen::<[u8; 20]>()).to_string()
}

let eth_addrs: Vec<String> = (0..3).map(|_| generate_random_eth_address()).collect();

175-178: LGTM: Event and parameter renaming in E3Requested

The replacement of CommitteeRequested with E3Requested and the renaming of parameters (nodecount to threshold_m, sortition_seed to seed) align well with the PR objectives. These changes enhance clarity and consistency with EVM events.

Consider adding a brief comment or documentation to explain the significance of E3Requested and the meaning of threshold_m for better code readability and maintainability.

Also applies to: 214-217


345-348: LGTM: Consistent event modifications in second test case

The changes to E3Requested and CiphernodeSelected events in this test case are consistent with earlier modifications, maintaining uniformity across the test suite.

Consider creating a helper function to generate test E3Requested events to reduce code duplication and improve maintainability:

fn create_test_e3_requested(e3_id: &str, threshold_m: u32, seed: u64) -> EnclaveEvent {
    EnclaveEvent::from(E3Requested {
        e3_id: E3id::new(e3_id),
        threshold_m,
        seed,
        moduli: vec![0x3FFFFFFF000001],
        degree: 2048,
        plaintext_modulus: 1032193,
        crp: vec![1, 2, 3, 4],
    })
}

// Usage:
let evt_1 = create_test_e3_requested("1234", 3, 123);
let evt_2 = create_test_e3_requested("1235", 3, 123);

Also applies to: 355-358, 367-367


Line range hint 1-427: Overall assessment: Changes align well with PR objectives

The modifications in this file consistently work towards:

  1. Moving away from alloy types (e.g., changing Address to String/&str).
  2. Synchronizing events with EVM (renaming CommitteeRequested to E3Requested).
  3. Improving clarity (renaming parameters like nodecount to threshold_m).

These changes align well with the stated PR objectives. The code maintains consistency across different parts of the file, including test cases. Consider implementing the suggested refactors to further improve code organization and maintainability.

As the codebase continues to evolve, consider creating a dedicated types module to centralize the definition and handling of core types like addresses and event structures. This can help maintain consistency and make future changes easier to implement across the codebase.

packages/ciphernode/core/src/evm.rs (2)

Line range hint 175-184: Handle errors instead of using .unwrap() on awaited results.

Using .unwrap() on the results of asynchronous operations can cause the application to panic on errors. To improve robustness, handle errors appropriately by propagating them or logging as necessary.

Apply this diff to handle potential errors:

- evm_listener
-     .send(AddEventHandler::<E3Requested>::new())
-     .await
-     .unwrap();
+ evm_listener
+     .send(AddEventHandler::<E3Requested>::new())
+     .await
+     .map_err(|e| error!("Failed to add E3Requested event handler: {}", e))?;

Adjust the method signature to return Result<Addr<Evm>> and propagate errors using ?. Repeat this change for other .unwrap() calls in the method.


66-66: Offer assistance to implement decode_e3_program_params.

There's a TODO indicating the need to decode e3ProgramParams. Proper decoding is crucial for correct operation. I can help implement this functionality to parse the ABI-encoded parameters.

Would you like me to assist in writing the decode_e3_program_params function or open a new GitHub issue to track this task?

packages/ciphernode/core/src/events.rs (2)

245-245: Ensure validation of node field after changing type to String

Changing the node field from Address to String removes the type safety that ensures valid Ethereum addresses. To prevent potential issues with invalid or malformed addresses, consider adding validation logic when setting or using this field.

You might implement a validation function or use a wrapper type that enforces the correct address format.

Also applies to: 253-253


306-306: Add validation for address field to maintain data integrity

With the address field now being a String, it's important to validate the address format to avoid errors caused by invalid addresses. This ensures robustness when the addresses are used elsewhere in the system.

Consider implementing address validation or utilizing a specialized type that encapsulates validation logic.

Also applies to: 314-314

The change from CommitteeRequested to E3Requested is in line with the PR objectives, specifically the task of converting EVM events to EnclaveEvents. This update ensures that the code now handles the new E3Requested event correctly.

To ensure consistency across the codebase, please run the following script to check for any remaining uses of CommitteeRequested:

packages/ciphernode/core/src/logger.rs (2)

Line range hint 1-54: Summary of logger.rs changes

The changes to this file are minimal, with only the addition of the Address import from the alloy crate. While this aligns with the PR objectives of EVM integration, the actual usage of this type is not visible in the current file.

Given the scope of the EVM integration described in the PR objectives, it's likely that more significant changes are present in other files. This file might be prepared for future updates or serve as a dependency for changes elsewhere in the codebase.

The changes look good, but please ensure that:

  1. The Address import is necessary and will be used.
  2. Any plans for updating event handling (especially for CiphernodeAdded) to use the Address type are documented or implemented consistently across the codebase.

3-3: Verify the necessity of the Address import.

The Address type from alloy::primitives is imported but not used in the visible code. This aligns with the PR objectives mentioning changes to address types, but its current usage is unclear.

Could you please clarify:

  1. Is this import intended for future use in this file?
  2. Is it used in a part of the file not shown in the diff?
  3. If neither, should this import be removed?

To help verify, you can run the following script:

#!/bin/bash
# Description: Check for usage of Address type in the logger.rs file

# Test: Search for Address usage in logger.rs
rg --type rust '\bAddress\b' packages/ciphernode/core/src/logger.rs

# If no results, it might be unused in this file
packages/ciphernode/core/src/ciphernode_selector.rs (3)

68-68: Approved: CiphernodeSelected event updated for consistency.

The change from nodecount to threshold_m in the CiphernodeSelected event creation is consistent with earlier modifications and maintains terminology alignment between events.

To ensure full consistency, please verify the structure of the CiphernodeSelected event:

#!/bin/bash
# Description: Verify the structure of the CiphernodeSelected event

# Test: Search for the definition of CiphernodeSelected event. Expect: To find the updated field names.
rg --type rust -A 10 'struct CiphernodeSelected'

Ensure that all fields in the CiphernodeSelected event match the corresponding fields in the E3Requested event for consistency.


47-52: Approved: Event handling updated to match new event structure.

The changes in the event handling logic correctly reflect the transition from CommitteeRequested to E3Requested, including the renaming of fields. This aligns with the PR objectives of synchronizing EVM events with contract events.

To ensure type safety and prevent potential overflow, please verify the type of threshold_m:

#!/bin/bash
# Description: Verify the type of threshold_m in the E3Requested event

# Test: Search for the definition of E3Requested event. Expect: To find the type of threshold_m.
rg --type rust -A 10 'struct E3Requested'

If threshold_m is not of type usize, consider adding a check to ensure it doesn't exceed usize::MAX before the cast:

let size = data.threshold_m.try_into().expect("threshold_m exceeds usize::MAX");

26-30: Approved: Attach method and event subscription updated.

The attach method has been correctly updated to accept a &str instead of Address, maintaining consistency with previous changes. The event subscription has also been updated to "E3Requested", aligning with the PR objectives.

To ensure the event name change is consistent across the codebase, please run the following verification script:

Verification successful

Verification Needed: Event name change script encountered an error.

The previous verification script failed due to a syntax error, preventing a complete check of the event name changes. Please run the corrected script below to ensure that "CommitteeRequested" is fully removed and "E3Requested" is consistently used across the codebase.

1-23: Overall, changes align well with EVM integration objectives.

The modifications to this file, including the updated Args struct and the changes in the main function, are consistent with the PR's goal of integrating EVM functionality. The addition of rpc and registry_contract parameters, along with the parsing of the registry contract address, supports the objectives outlined in the PR.

However, there are opportunities to enhance the robustness of the code:

  1. Improve error handling, especially for address parsing.
  2. Add validation for the rpc argument.
  3. Consider adding more detailed logging or error messages to aid in debugging and maintenance.

These enhancements would further improve the reliability and maintainability of the EVM integration.

packages/ciphernode/enclave_node/src/bin/node.rs (2)

10-15: LGTM with a minor suggestion for consistency

The addition of rpc, enclave_contract, and registry_contract fields to the Args struct aligns well with the PR objectives for EVM integration. These new fields will allow the necessary parameters to be passed for connecting to the Ethereum network and interacting with smart contracts.

For consistency, consider using the same flag style for all fields. Currently, rpc uses a short flag (-n), while enclave_contract and registry_contract use long-form flags. You might want to either:

  1. Add short flags for enclave_contract and registry_contract, or
  2. Remove the short flag for rpc and use only long-form flags for all fields.

Example of option 1:

#[arg(short='n', long)]
rpc: String,
#[arg(short='e', long="enclave-contract")]
enclave_contract: String,
#[arg(short='r', long="registry-contract")]
registry_contract: String

23-24: LGTM with a suggestion for improved error handling

The addition of registry_contract and enclave_contract parsing aligns well with the new fields in the Args struct. The use of Address::parse_checksummed ensures that only valid Ethereum addresses are accepted.

Consider improving the error handling by providing more specific error messages. This will make debugging easier for users who might input incorrect addresses. For example:

let registry_contract = Address::parse_checksummed(&args.registry_contract, None)
    .expect("Invalid registry contract address");
let enclave_contract = Address::parse_checksummed(&args.enclave_contract, None)
    .expect("Invalid enclave contract address");

This change would make it clearer which specific address is invalid if an error occurs.

packages/ciphernode/enclave_node/Cargo.toml (1)

Line range hint 1-30: Consider specifying versions for git dependencies.

The Cargo.toml file looks well-structured overall. However, for better maintainability and reproducibility, consider specifying exact commit hashes or tags for the git dependencies (e.g., fhe, fhe-traits, fhe-util).

Example of how to specify a git dependency with a commit hash:

fhe = { git = "https://github.com/gnosisguild/fhe.rs", rev = "abcdef123456", version = "0.1.0-beta.7" }

This ensures that builds are reproducible and helps prevent unexpected changes when the remote repository is updated.

packages/ciphernode/core/src/cipernode_selector.rs (3)

10-10: Approved: Address field type changed to String

The change from Address to String for the address field aligns with the PR objective of excluding alloy types from the domain. This change provides more flexibility in handling addresses.

Consider introducing a type alias for address strings to improve code readability and maintainability:

type AddressString = String;

pub struct CiphernodeSelector {
    // ...
    address: AddressString,
}

This approach maintains the flexibility of using strings while providing a clear semantic meaning for address-related variables throughout the codebase.


18-22: Approved: Constructor updated to accept &str for address

The new method has been correctly updated to accept a &str for the address parameter, which is consistent with the address field type change. This change allows for more flexible usage of the method.

Consider using String::from(address) instead of address.to_owned() for clarity:

address: String::from(address),

Both methods have the same effect, but String::from() might be slightly more idiomatic and explicit about the conversion from &str to String.


30-30: Approved: Event handling updated for E3Requested event

The changes in event handling, including the event name update from "CommitteeRequested" to "E3Requested" and the corresponding data extraction updates, align well with the PR objectives. The use of seed and threshold_m fields is consistent with the new event structure.

Consider adding error logging for unexpected event types:

let EnclaveEvent::E3Requested { data, .. } = event else {
    log::warn!("Unexpected event type received: {:?}", event);
    return;
};

This addition would help in debugging by providing visibility into any unexpected events that might be received.

Line range hint 84-104: LGTM with suggestion: Address type replaced, but import remains

The change from Address to &str for the addr parameter aligns with the PR objective of excluding alloy types from the domain. The CiphernodeSelector::attach call with the addr parameter is consistent with this change.

However, the Address import from alloy::primitives is still present in the file (line 65). Consider removing this unused import to complete the transition away from alloy types.

Remove the unused Address import from alloy::primitives on line 65.


176-179: LGTM: Event and parameter renaming

The replacement of CommitteeRequested with E3Requested and the renaming of parameters (nodecount to threshold_m and sortition_seed to seed) align with the PR objectives and the overall renaming of events.

Consider updating any relevant documentation or comments to reflect these terminology changes, especially regarding the meaning and usage of threshold_m compared to the previous nodecount.


Line range hint 1-428: Summary: Good progress on EVM integration, minor improvements needed

Overall, the changes in this file align well with the PR objectives for EVM integration. The renaming of events (e.g., CommitteeRequested to E3Requested) and parameters (e.g., nodecount to threshold_m) has been consistently applied throughout the file, including in tests.

Key points:

  1. The transition from Address to String for Ethereum addresses is mostly complete, but there are still remnants of Address usage that need to be addressed.
  2. New modules (cipernode_selector and evm_enclave) have been added, which likely contribute to the EVM integration.
  3. Test cases have been updated to reflect the new event and parameter names.

Next steps:

  1. Complete the removal of the Address type dependency, particularly in the address generation logic (lines 129-135).
  2. Remove the unused Address import from alloy::primitives.
  3. Update any relevant documentation to reflect the new terminology (e.g., explaining the significance of threshold_m vs. the old nodecount).
  4. Consider adding new tests or expanding existing ones to cover any new functionality introduced by the EVM integration.

As you continue with the EVM integration, keep in mind the following:

  • Ensure that the new cipernode_selector and evm_enclave modules are well-documented and have appropriate test coverage.
  • Consider the performance implications of using String for Ethereum addresses instead of a more specialized type. While it simplifies the code, it might impact performance in high-throughput scenarios.
  • Evaluate if any additional error handling or validation is needed for the new EVM-related functionality, especially when dealing with external inputs or events.

There's a TODO indicating that e3ProgramParams needs to be decoded from ABI-encoded bytes. Implementing this decoding is crucial for correctly extracting the parameters required for E3Requested. I can help provide the decoding logic if you'd like.

Would you like me to generate the code to decode e3ProgramParams or open a GitHub issue to track this task?

8-15: LGTM! Consider adding documentation for the new fields.

The changes to the Args struct align well with the PR objectives for EVM integration. The new fields provide the necessary information for connecting to the Ethereum network and interacting with the required smart contracts.

Consider adding brief documentation comments for each new field to improve code readability and maintainability. For example:

/// RPC endpoint for the Ethereum network
#[arg(short = 'n', long)]
rpc: String,

/// Address of the enclave contract
#[arg(short, long = "enclave-contract")]
enclave_contract: String,

/// Address of the registry contract
#[arg(short, long = "registry-contract")]
registry_contract: String,

/// Optional path to write the public key
#[arg(short, long = "pubkey-write-path")]
pubkey_write_path: Option<String>,
packages/ciphernode/core/src/public_key_writer.rs (1)

1-5: Remove unused import.

The Address import from the alloy crate is not used in this file.

Consider removing the unused import:

-use alloy::primitives::Address;
packages/ciphernode/core/src/main_aggregator.rs (1)

43-48: LGTM: Method signature updated to support EVM integration.

The new parameters in the attach method signature align well with the PR objectives for EVM integration. The addition of rpc_url, enclave_contract, and registry_contract parameters enables flexible configuration of EVM connections. The optional pubkey_write_path parameter provides good flexibility for public key handling.

Consider adding documentation comments for the new parameters to improve code readability and maintainability. For example:

/// Attaches the MainAggregator and sets up necessary connections.
///
/// # Arguments
///
/// * `rpc_url` - The URL for the EVM RPC endpoint.
/// * `enclave_contract` - The address of the EVM enclave contract.
/// * `registry_contract` - The address of the EVM ciphernode registry contract.
/// * `pubkey_write_path` - Optional path to write public keys.
///
/// # Returns
///
/// A tuple containing the `Addr<Self>` and a `JoinHandle<()>`.

Line range hint 1-383: Summary: Debug code added, consider removal for production.

The changes in this file are limited to adding debug-related code:

  1. Importing the Hardhat console library.
  2. Adding console.log statements in the request function.

While these changes don't affect the core functionality of the contract, they raise concerns about including debug code in production deployments.

Consider implementing a systematic approach to manage debug code across your project:

  1. Use conditional compilation or a similar mechanism to easily toggle debug code.
  2. Establish a clear policy for handling debug code in your development workflow.
  3. Implement a pre-deployment checklist that includes verifying the removal of all debug code.
  4. Consider using events for logging important information instead of console.log statements, as events can be more gas-efficient and are a standard way of exposing contract activity.

52-52: Avoid unnecessary cloning in process methods

In the process implementations for both CiphernodeAdded and CiphernodeRemoved, self.clone() is used before converting into event structures. To improve performance and reduce unnecessary cloning, implement From for references to these types.

+    fn from(value: &CiphernodeAdded) -> Self {
+        events::CiphernodeAdded {
+            address: value.node.to_string(),
+            index: value.index.as_limbs()[0] as usize,
+            num_nodes: value.numNodes.as_limbs()[0] as usize,
+            size: value.size.as_limbs()[0] as usize,
+        }
+    }
+}

impl ContractEvent for CiphernodeAdded {
    fn process(&self, bus: Addr<EventBus>) -> Result<()> {
-        let data: events::CiphernodeAdded = self.clone().into();
+        let data: events::CiphernodeAdded = self.into();
        bus.do_send(EnclaveEvent::from(data));
        Ok(())
    }
}

Repeat the same for CiphernodeRemoved:

+impl<'a> From<&'a CiphernodeRemoved> for events::CiphernodeRemoved {
+    fn from(value: &CiphernodeRemoved) -> Self {
+        events::CiphernodeRemoved {
+            address: value.node.to_string(),
+            index: value.index.as_limbs()[0] as usize,
+            num_nodes: value.numNodes.as_limbs()[0] as usize,
+            size: value.size.as_limbs()[0] as usize,
+        }
+    }
+}

impl ContractEvent for CiphernodeRemoved {
    fn process(&self, bus: Addr<EventBus>) -> Result<()> {
-        let data: events::CiphernodeRemoved = self.clone().into();
+        let data: events::CiphernodeRemoved = self.into();

20-32: ⚠️ Potential issue

Improve error handling and input validation

The changes correctly implement the new argument parsing and MainAggregator::attach call for EVM integration. However, there are some improvements to be made in error handling and input validation:

  1. The use of expect for parsing addresses can lead to abrupt termination. Consider using a more graceful error handling approach.
  2. There's no validation for the rpc argument, as mentioned in a previous review.

Here's a suggested improvement:

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let args = Args::parse();
    println!("LAUNCHING AGGREGATOR");

    let registry_contract = Address::parse_checksummed(&args.registry_contract, None)
        .map_err(|e| format!("Invalid registry contract address: {}", e))?;

    let enclave_contract = Address::parse_checksummed(&args.enclave_contract, None)
        .map_err(|e| format!("Invalid enclave contract address: {}", e))?;

    if !args.rpc.starts_with("http://") && !args.rpc.starts_with("https://") {
        return Err("RPC URL must start with http:// or https://".into());
    }

    let (_, handle) = MainAggregator::attach(
        &args.rpc,
        enclave_contract,
        registry_contract,
        args.pubkey_write_path.as_deref(),
    )
    .await?;

    let _ = tokio::join!(handle);
    Ok(())
}

This implementation:

  1. Uses ? operator for more graceful error handling of address parsing.
  2. Adds basic validation for the rpc URL.
  3. Propagates any errors from MainAggregator::attach using ?.

To ensure that the MainAggregator::attach method is correctly implemented with the new parameters, let's verify its definition:

packages/ciphernode/core/src/public_key_writer.rs (4)

7-9: LGTM: PublicKeyWriter struct definition.

The PublicKeyWriter struct is well-defined with a single path field of type String.


25-27: LGTM: Actor trait implementation.

The Actor trait implementation for PublicKeyWriter is correct and sufficient.


1-46: Overall assessment: Good implementation with room for minor improvements.

The PublicKeyWriter actor is well-structured and implements the necessary functionality for writing aggregated public keys to a file. The code is generally clean and follows good practices. However, there are a few areas where improvements can be made:

  1. Remove the unused Address import.
  2. Consider more specific event subscription instead of using a wildcard.
  3. Improve error handling in the event handler and append_relative_path function.
  4. Add logging for better debugging and error tracing.

These changes will enhance the robustness and maintainability of the code. Great job on implementing this new feature!


29-40: 🛠️ Refactor suggestion

Verify event handling logic and error handling.

The event handling logic looks correct, but there are a few points to consider:

  1. The clone() call on msg might be unnecessary if you're only pattern matching.
  2. Error handling for the file write operation could be improved.

To ensure the PublicKeyAggregated event is properly defined and used consistently:

Consider updating the handler implementation:

impl Handler<EnclaveEvent> for PublicKeyWriter {
    type Result = ();
-   fn handle(&mut self, msg: EnclaveEvent, _: &mut Self::Context) -> Self::Result {
-       if let EnclaveEvent::PublicKeyAggregated { data, .. } = msg.clone() {
+   fn handle(&mut self, msg: EnclaveEvent, _: &mut Self::Context) -> Self::Result {
+       if let EnclaveEvent::PublicKeyAggregated { data, .. } = msg {
            let pubkey_str = BASE64_STANDARD.encode(&data.pubkey);

            if let Some(path) = append_relative_path(&self.path) {
-               fs::write(path, &pubkey_str).unwrap();
+               if let Err(e) = fs::write(path, &pubkey_str) {
+                   log::error!("Failed to write public key to file: {}", e);
+               }
            }
        }
    }
}
Verification successful

Clone Removed and Error Handling Enhanced

The clone() call on msg is unnecessary as EnclaveEvent is owned during pattern matching. Additionally, error handling for the file write operation has been appropriately improved in the updated handler implementation.

50-52: LGTM! Consider adding a status check loop.

The final wait state and user prompt are well-implemented. To further improve user experience and monitoring capabilities, consider adding a status check loop:

echo "All processes are running. Press Ctrl+C to stop and clean up."
while true; do
    echo "Checking process status..."
    # Add commands to check the status of key processes
    # For example:
    # ps aux | grep "[c]iphernode:launch" || echo "Warning: Ciphernode process not found"
    # ps aux | grep "[c]iphernode:aggregator" || echo "Warning: Aggregator process not found"
    sleep 60  # Check every minute
done

This addition would provide periodic status updates, making it easier to monitor the long-running processes.

1-13: LGTM: Import changes align with new functionality.

The new imports for EVM-related functions and PublicKeyWriter are consistent with the changes in the attach method. The addition of alloy::primitives::Address import supports the EVM integration objectives mentioned in the PR summary.


74-78: LGTM: Public key writing and logging setup.

The conditional setup of PublicKeyWriter based on the pubkey_write_path parameter is well-implemented, providing flexibility in public key handling. The change in the logger identifier from "AGGREGATOR" to "AGG" is a minor modification that doesn't affect functionality.

10-18: LGTM: Well-structured command-line arguments.

The Args struct is well-defined using clap derive macros, which will greatly simplify command-line argument parsing. The inclusion of input and output fields aligns with the PR objective of enhancing script flexibility.

Consider adding help messages to the input and output arguments to provide more context to users. You can do this by adding a help attribute to each argument:

#[arg(short, long, help = "Path to the input file containing the public key")]
input: String,

#[arg(short, long, help = "Path to save the encrypted output")]
output: String,

23-25: LGTM: Proper use of user-specified input path.

The code correctly uses the user-specified input path (args.input) to read the public key, which aligns with the PR objectives of enhancing script flexibility. The print statement provides useful feedback to the user.

Consider adding more robust error handling. For example, you could use fs::read_to_string(&args.input).map_err(|e| format!("Failed to read input file: {}", e))? to provide a more informative error message if the file read fails.


41-42: LGTM: Proper use of user-specified output path.

The code correctly uses the user-specified output path (args.output) to write the encrypted data, which aligns with the PR objectives of enhancing script flexibility. The print statement provides useful feedback to the user.

Consider adding more robust error handling. For example, you could use fs::write(&args.output, &ciphertext_bytes).map_err(|e| format!("Failed to write output file: {}", e))? to provide a more informative error message if the file write fails.

2-2: LGTM: Good choice for command-line argument parsing.

The addition of the clap crate is a solid choice for implementing command-line argument parsing. It's a well-maintained and widely used library in the Rust ecosystem, which will enhance the flexibility and usability of the script.


21-21: LGTM: Proper implementation of command-line argument parsing.

The use of Args::parse() is the correct way to parse command-line arguments with the clap crate. This change successfully implements the flexibility enhancements outlined in the PR objectives.


Line range hint 1-44: Overall: Excellent implementation of command-line argument parsing.

The changes in this file successfully implement command-line argument parsing using the clap crate, which aligns perfectly with the PR objectives of enhancing script flexibility. The script now uses user-specified input and output paths instead of hardcoded values, making it more versatile and user-friendly.

The implementation follows Rust and clap best practices, and the code structure is clean and easy to understand. The added print statements provide useful feedback to the user about file operations.

These changes contribute significantly to the overall goal of improving the flexibility and usability of the EVM integration process.

packages/ciphernode/core/src/fhe.rs (5)

1-19: LGTM! Consider grouping related imports.

The changes to imports and new struct definitions look good and align with the updated event handling and new methods in the Fhe struct.

Consider grouping related imports for better readability. For example:

use crate::{ordered_set::OrderedSet, ActorFactory, E3Requested, EnclaveEvent};
use anyhow::*;
use fhe::{
    bfv::{BfvParameters, BfvParametersBuilder, Ciphertext, Encoding, Plaintext, PublicKey, SecretKey},
    mbfv::{AggregateIter, CommonRandomPoly, DecryptionShare, PublicKeyShare},
};
use fhe_traits::{DeserializeParametrized, FheDecoder, Serialize};
use rand_chacha::ChaCha20Rng;
use std::sync::{Arc, Mutex};

62-85: Approve changes with suggestions for improved error handling.

The new generate_keyshare and decrypt_ciphertext methods simplify the interface and improve secret key handling. However, there's room for improvement in error handling.

Consider improving error handling in decrypt_ciphertext:

  1. Use ? operator instead of unwrap() in line 84.
  2. Add more specific error context for each operation. For example:
pub fn decrypt_ciphertext(&self, msg: DecryptCiphertext) -> Result<Vec<u8>> {
    let DecryptCiphertext { unsafe_secret, ciphertext } = msg;

    let secret_key = SecretKeySerializer::from_bytes(&unsafe_secret, self.params.clone())
        .context("Failed to deserialize secret key")?;
    let ct = Arc::new(
        Ciphertext::from_bytes(&ciphertext, &self.params)
            .context("Failed to deserialize ciphertext")?
    );
    let decryption_share = DecryptionShare::new(&secret_key, &ct, &mut *self.rng.lock().unwrap())
        .context("Failed to create decryption share")?;
    Ok(decryption_share.to_bytes())
}

88-113: Approve changes with suggestions for improved error handling.

The new get_aggregate_public_key and get_aggregate_plaintext methods correctly implement the aggregation logic. However, error handling can be improved.

Consider adding more context to potential errors:

  1. In get_aggregate_public_key:
pub fn get_aggregate_public_key(&self, msg: GetAggregatePublicKey) -> Result<Vec<u8>> {
    let public_key: PublicKey = msg
        .keyshares
        .iter()
        .map(|k| PublicKeyShare::deserialize(k, &self.params, self.crp.clone())
            .context("Failed to deserialize public key share"))
        .aggregate()
        .context("Failed to aggregate public key shares")?;

    Ok(public_key.to_bytes())
}
  1. In get_aggregate_plaintext:
pub fn get_aggregate_plaintext(&self, msg: GetAggregatePlaintext) -> Result<Vec<u8>> {
    let arc_ct = Arc::new(Ciphertext::from_bytes(
        &msg.ciphertext_output,
        &self.params,
    ).context("Failed to deserialize ciphertext")?);

    let plaintext: Plaintext = msg
        .decryptions
        .iter()
        .map(|k| DecryptionShare::deserialize(k, &self.params, arc_ct.clone())
            .context("Failed to deserialize decryption share"))
        .aggregate()
        .context("Failed to aggregate decryption shares")?;

    let decoded = Vec::<u64>::try_decode(&plaintext, Encoding::poly())
        .context("Failed to decode plaintext")?;
    Ok(bincode::serialize(&decoded)
        .context("Failed to serialize decoded plaintext")?)
}

119-138: Approve changes with suggestions for improved error handling.

The update to use EnclaveEvent::E3Requested and the simplified Fhe instance creation look good. However, error handling can be improved.

Consider replacing unwrap() with proper error handling:

pub fn create(rng: Arc<Mutex<ChaCha20Rng>>) -> ActorFactory {
    Box::new(move |ctx, evt| {
        let EnclaveEvent::E3Requested { data, .. } = evt else {
            return;
        };
        let E3Requested {
            degree,
            moduli,
            plaintext_modulus,
            crp,
            ..
        } = data;

        match Fhe::from_raw_params(&moduli, degree, plaintext_modulus, &crp, rng.clone()) {
            Ok(fhe) => ctx.fhe = Some(Arc::new(fhe)),
            Err(e) => eprintln!("Failed to create Fhe instance: {}", e),
        }
    })
}

This approach provides better error handling and logging in case of failure.


160-172: LGTM! Consider adding safety documentation.

The unsafe_serialize and deserialize methods correctly implement the serialization and deserialization logic for SecretKey.

Consider adding documentation comments to explain the safety implications of these methods, especially for unsafe_serialize. For example:

impl SecretKeySerializer {
    /// Serializes the SecretKey into a byte vector.
    /// 
    /// # Safety
    /// This method is marked as unsafe because it exposes the raw coefficients of the SecretKey.
    /// Use with caution and ensure proper handling of the serialized data to maintain security.
    pub fn unsafe_serialize(&self) -> Result<Vec<u8>> {
        // ... (existing implementation)
    }

    /// Deserializes a byte vector into a SecretKeySerializer.
    /// 
    /// # Parameters
    /// * `bytes` - The byte vector to deserialize.
    /// * `params` - The BfvParameters used to reconstruct the SecretKey.
    ///
    /// # Safety
    /// Ensure that the input bytes come from a trusted source and were originally serialized
    /// using the `unsafe_serialize` method to maintain the integrity of the SecretKey.
    pub fn deserialize(bytes: &[u8], params: Arc<BfvParameters>) -> Result<SecretKeySerializer> {
        // ... (existing implementation)
    }
}
packages/ciphernode/core/src/plaintext_aggregator.rs (2)

69-72: LGTM. Consider using shares.len() >= *threshold_m.

The add_share method has been correctly updated to use threshold_m instead of nodecount. The inclusion of ciphertext_output in the Computing state is consistent with previous changes.

A minor suggestion: Consider changing the condition on line 79 to shares.len() >= *threshold_m to handle cases where more shares than necessary are received.

-        if shares.len() == *threshold_m {
+        if shares.len() >= *threshold_m {

Also applies to: 79-82


154-161: LGTM. Consider adding error handling for get_aggregate_plaintext.

The Handler<ComputeAggregate> implementation has been correctly updated to handle the new ciphertext_output field. The new logic for updating the state and dispatching the PlaintextAggregated event is appropriate and aligns with the PR objectives.

A minor suggestion: Consider adding explicit error handling for the get_aggregate_plaintext call, as it returns a Result.

-        let decrypted_output = self.fhe.get_aggregate_plaintext(GetAggregatePlaintext {
-            decryptions: msg.shares.clone(),
-            ciphertext_output: msg.ciphertext_output
-        })?;
+        let decrypted_output = self.fhe.get_aggregate_plaintext(GetAggregatePlaintext {
+            decryptions: msg.shares.clone(),
+            ciphertext_output: msg.ciphertext_output
+        }).map_err(|e| anyhow::anyhow!("Failed to get aggregate plaintext: {}", e))?;

Also applies to: 174-190

packages/ciphernode/core/src/lib.rs (3)

57-57: LGTM: Event changes align with PR objectives

The renaming of CommitteeRequested to E3Requested and the addition of new events (E3id, CiphernodeAdded, CiphernodeSelected, CiphertextOutputPublished) align well with the PR objectives of synchronizing EVM events with contract events.

Consider adding a brief comment explaining the purpose of the E3Requested event and how it differs from the previous CommitteeRequested event. This would help maintain clarity for future developers working on this code.

Also applies to: 60-62


199-201: LGTM: Simplified public key handling

The changes in public key share generation and aggregation, particularly the direct use of to_bytes() method on PublicKeyShare objects and the simplified aggregation process, improve code readability and align with the PR objectives of enhancing cryptographic operations handling.

Consider adding a brief comment explaining the public key aggregation process, especially for developers who might not be familiar with the cryptographic concepts involved. This would enhance the code's maintainability.

Also applies to: 224-236


247-252: LGTM: Added plaintext padding function

The addition of the pad_end function improves the handling of plaintext data by ensuring consistent length for cryptographic operations. This aligns well with the PR objectives of enhancing the overall cryptographic process.

Consider adding a brief comment explaining why padding is necessary and how the total length is determined. This would provide valuable context for future maintainers. Also, consider using the vec! macro for a more idiomatic Rust implementation:

fn pad_end(input: &[u64], pad: u64, total: usize) -> Vec<u64> {
    let mut result = input.to_vec();
    result.resize(total, pad);
    result
}
packages/ciphernode/core/src/keyshare.rs (2)

Line range hint 155-157: Ensure Rust version compatibility with let ... else syntax

The let ... else syntax used here requires Rust version 1.65 or later. Ensure that your project's Rust version is updated accordingly to avoid compilation errors on older compilers.


Line range hint 159-165: Undefined fields ctx.fhe and ctx.keyshare

In the closure, ctx.fhe and ctx.keyshare are accessed, but it's unclear if the ctx object has these fields defined. Verify that ctx has the fhe and keyshare fields, or adjust the code to access these fields appropriately.

packages/ciphernode/core/src/logger.rs (2)

35-36: Improved logging format for PublicKeyAggregated event

The inclusion of the logger's name in the output enhances the clarity of log messages. This change is beneficial for debugging and monitoring, especially in systems with multiple loggers.


44-44: Syntax adjustment for CiphernodeAdded event handling

The addition of a comma after the closing brace is a necessary syntactical adjustment to prepare for the new E3Requested event case. This change ensures proper Rust syntax.

packages/ciphernode/core/src/e3_request.rs (3)

19-19: LGTM! Good use of derive macro.

The addition of #[derive(Default)] for the EventBuffer struct is a good practice. It simplifies the code by automatically implementing the Default trait, reducing the chance of errors that could occur in a manual implementation.


Line range hint 1-141: Summary: Changes align well with PR objectives

The modifications in this file contribute significantly to the EVM integration objectives:

  1. The transition from Ciphernode to Keyshare aligns with the goal of synchronizing EVM events with contract events.
  2. The use of Arc<Fhe> instead of Addr<Fhe> suggests an optimization in the event handling mechanism.
  3. The automatic derivation of Default for EventBuffer improves code maintainability.

These changes appear to be consistent and well-implemented, supporting the overall goal of EVM integration.


41-42: LGTM! Verify consistency of keyshare usage.

The update to the recipients method correctly reflects the changes made to the E3RequestContext struct, now using keyshare instead of ciphernode.

To ensure consistent usage of keyshare across the codebase, run the following script:

#!/bin/bash
# Description: Verify consistent usage of keyshare

# Test: Check for any remaining usages of 'ciphernode' in method implementations
echo "Checking for remaining 'ciphernode' usages in methods:"
ast-grep --lang rust --pattern $'impl $_ {
  $$$
  fn $_($_) $_? {
    $$$
    ciphernode
    $$$
  }
  $$$
}'
packages/ciphernode/core/src/fhe.rs (2)

140-153: LGTM! Good encapsulation of SecretKey serialization logic.

The introduction of the SecretKeySerializer struct and its methods for serializing and deserializing SecretKey is a good improvement. It encapsulates the serialization logic and provides a clear interface for handling secret keys.


155-159: LGTM! Appropriate use of serde for SecretKeyData.

The SecretKeyData struct is well-defined for serialization purposes. The use of serde::Serialize and serde::Deserialize derive macros is appropriate for this use case.

tests/basic_integration/test.sh (9)

3-3: Good use of error handling with set -eu.

The set -eu command is a good practice as it exits the script if any command fails and treats unset variables as an error. This helps catch issues early in the script execution.


49-69: Well-implemented waiton-files function with timeout.

The waiton-files function is well-implemented with a timeout mechanism. This prevents the script from hanging indefinitely if the expected files are never created.

71-73: Ensure clean environment before test execution.

Killing existing processes that might interfere with the test is a good practice. It helps ensure that the test runs in a clean environment.


76-76: Good use of trap for error handling.

Setting up a trap to catch errors and interrupts is an excellent practice. It ensures that the cleanup function is called even if the script exits unexpectedly.


107-107: Good use of waiton-files function.

Using the waiton-files function to ensure that necessary files exist before proceeding is a good practice. It helps prevent race conditions and ensures that the required components are ready.


165-165: Good practice: Calling cleanup function at the end.

Calling the cleanup function at the end of the script ensures that all background processes are properly terminated, even if the test passes. This is a good practice for maintaining a clean environment.


1-166: Overall assessment: Well-structured integration test script with room for improvements.

This integration test script is comprehensive and covers the necessary steps for testing the system. It includes good practices such as error handling, process management, and verification steps. However, there are several areas where the script could be improved for better robustness and maintainability:

  1. Consider using a configuration file for environment variables.
  2. Improve the robustness of the cleanup function by quoting command substitution.
  3. Add timeouts to waiting mechanisms to prevent potential infinite loops.
  4. Refactor repetitive sections, such as ciphernode addition, to reduce code duplication.
  5. Replace fixed sleep intervals with more precise waiting mechanisms where possible.
  6. Enhance the plaintext verification logic for more accurate comparisons.

Implementing these suggestions would make the script more resilient to edge cases and easier to maintain in the long run.

79-79: ⚠️ Potential issue

Ensure safe removal of output artifacts.

When using rm -rf with variables, it's important to quote the variable to prevent issues if the variable is empty or contains spaces.

Consider modifying the line as follows:

-rm -rf $ROOT_DIR/tests/basic_integration/output/*
+rm -rf "$ROOT_DIR/tests/basic_integration/output/"*

This change ensures that the rm command works as expected even if $ROOT_DIR contains spaces.

Likely invalid or redundant comment.


27-31: ⚠️ Potential issue

Improve robustness of the cleanup function.

The cleanup function is using unquoted command substitution, which can lead to word splitting issues if multiple job IDs are returned.

Consider quoting the command substitution:

 cleanup() {
     echo "Cleaning up processes..."
-    kill $(jobs -p) 2>/dev/null
+    kill "$(jobs -p)" 2>/dev/null
     exit ${1:-1}
 }

This change ensures that all job IDs are properly handled, even if there are spaces or special characters.

Likely invalid or redundant comment.
