December 2025: sigp/lighthouse (Lighthouse repo) - Delivered a critical fix to BLS signature aggregation edge-cases, improving correctness in cryptographic aggregation. Implemented handling for the is_infinity flag when aggregating onto an empty AggregateSignature, addressing subtle edge-cases that could lead to invalid results during multi-signature aggregation. The change is recorded in commit cd0b1ef6485d05c8920d308d8c2470f0f5f3fceb, co-authored by figtracer and Michael Sproul to ensure clear attribution and collaboration. This work reduces risk of incorrect aggregations in production validators and strengthens the cryptographic robustness of Lighthouse.
