EigenDA v0.5.0

Summary

This major upgrade includes several new features, security improvements, and an API breaking change that simplifies the blob dispersal endpoint.

Notable features that directly affect users are:

• Rollups - Disperser API breaking change: The API for DisperseBlob request has been simplified, and security_params field is no longer supported. Default quorums are enforced by the protocol and additional quorums can be specified in custom_quorum_numbers field.
• Rollups - Disperser API error codes: The disperser API returns structured error codes along with the error messages.
• Rollups - Retrieval rate limits: We’ve added rate limits for RetrieveBlob endpoint.
• Operators - Operator CLI is revamped: update-quorums command is no longer supported, and opt-out command takes specific quorums to be opted out (instead of opting out of all quorums)

Other improvements:

• This upgrade spans changes in contracts, disperser, and DA nodes to enable blob dispersals across multiple quorums
• Revamped logic for operator nonsigning accounting across multiple quorums
• Fireblocks MPC wallet support for disperser
• Automatic failover among multiple RPC endpoints
• More robust selection of reference block
• Other security patches and bug fixes
