Decryption Committee

Definition ∞ A decryption committee is a designated group of participants responsible for collectively decrypting sensitive data within a cryptographic system. This committee operates within privacy-preserving blockchain protocols, where individual members hold partial keys necessary to unlock encrypted information. No single member can decrypt the data alone, requiring a threshold of committee members to cooperate. This distributed approach prevents any single point of failure or centralized control over sensitive data, enhancing security and trust. It is often utilized in confidential transaction systems or secure data sharing platforms.
Context ∞ News about decryption committees typically arises in the context of privacy-focused blockchain solutions and zero-knowledge proof applications. Discussions often concern the selection and rotation of committee members, the security of their partial keys, and the protocols governing their collective action. The integrity and composition of such committees are vital for the overall security and privacy assurances offered by these advanced cryptographic systems, particularly in regulated environments.
