Obol Charon
June 2023
Sigma Prime assessed Obol Charon across distributed-validator cryptographic flows, message validation, networked runtime behavior, and safety checks. The case study is relevant for DVT and staking infrastructure teams where cluster coordination and malformed messages can affect validator safety.
Executive summary
Sigma Prime assessed Obol Charon with focus on distributed-validator cryptographic flows, message-source validation, and runtime safety checks. The review identified critical/high findings as well as medium/low/informational issues relevant to robustness and correctness. The report strengthens cluster safety by hardening DKG/message handling and reducing failure-prone edge-case behavior.
