v0.3.0-rc.1 - Slashing

What's Changed

Added 🎉

• feat: new BLS aggregation service interface by @maximopalopoli in #578

  • The new interface implies starting the service before using it, interact with it using a handler and receiving the aggregated responses in a separate channel.

  • An example using the interface is:

    // initialize service
    blsAgg := NewBlsAggregatorBuilder(fakeAvsRegistryService, hashFunction, logger)
    handler, aggResponsesC := blsAgg.Start()
    
    // Initialize task
    metadata := NewTaskMetadata(taskIndex, blockNum, quorumNumbers, quorumThresholdPercentages, tasksTimeToExpiry)
    err := handler.InitializeNewTask(metadata)
    
    // Process signature
    taskSignature := NewTaskSignature(taskIndex, taskResponse, blsSig, testOperator1.OperatorId)
    err = handler.ProcessNewSignature(
      context.Background(),
      taskSignature,
    )
    
    // Receive responses
    aggregationServiceResponse := <-aggResponsesC

Fixes

Breaking Changes 🛠

• refactor: encapsulate parameters into TaskSignature in #487

  • Introduced TaskSignature struct to encapsulate parameters related to task signatures:

  • Updated ProcessNewSignature to accept a TaskSignature struct instead of multiple parameters.

    // BEFORE
    blsAggServ.ProcessNewSignature(
        context.Background(),
        taskIndex,
        taskResponse,
        blsSigOp1,
        testOperator1.OperatorId,
    )
    
    // AFTER
    taskSignature := NewTaskSignature(taskIndex, taskResponse, blsSig, testOperator1.OperatorId)
    
    blsAggServ.ProcessNewSignature(
        context.Background(),
        taskSignature,
    )

• refactor: update interface on bls aggregation in #485.

  • Introduces a new struct TaskMetadata with a constructor NewTaskMetadata to initialize a new task and a method WithWindowDuration to set the window duration.

  • Refactors InitializeNewTask and singleTaskAggregatorGoroutineFunc to accept a TaskMetadata struct instead of multiple parameters.

    // BEFORE
    blsAggServ := NewBlsAggregatorService(fakeAvsRegistryService, hashFunction, logger)
    
    blsAggServ.InitializeNewTask(
        taskIndex,
        blockNum,
        quorumNumbers,
        quorumThresholdPercentages,
        tasksTimeToExpiry,
    )
    
    // AFTER
    blsAggServ := NewBlsAggregatorService(fakeAvsRegistryService, hashFunction, logger)
    
    metadata := NewTaskMetadata(taskIndex, blockNum, quorumNumbers, quorumThresholdPercentages, tasksTimeToExpiry)
    blsAggServ.InitializeNewTask(metadata)

  • Removes InitializeNewTaskWithWindow since windowDuration can now be set in TaskMetadata.

    // BEFORE
    blsAggServ := NewBlsAggregatorService(fakeAvsRegistryService, hashFunction, logger)
    err = blsAggServ.InitializeNewTaskWithWindow(
        taskIndex,
        blockNum,
        quorumNumbers,
        quorumThresholdPercentages,
        timeToExpiry,
        windowDuration,
    )
    
    // AFTER
    blsAggServ := NewBlsAggregatorService(fakeAvsRegistryService, hashFunction, logger)
    
    metadata := NewTaskMetadata(
        taskIndex,
        blockNum,
        quorumNumbers,
        quorumThresholdPercentages,
        tasksTimeToExpiry,
    ).WithWindowDuration(windowDuration)
    blsAggServ.InitializeNewTask(metadata)
