Provable Broadcast

Definition ∞ Provable broadcast is a cryptographic mechanism ensuring that a message or data piece has been reliably and publicly transmitted across a decentralized network, with verifiable evidence of its dissemination. This system allows any participant to confirm that the broadcast occurred and that the information reached its intended recipients. It is critical for maintaining transparency and accountability in distributed systems. This approach prevents denial-of-service attacks against message propagation.
Context ∞ News often highlights provable broadcast as a key feature in secure communication protocols and decentralized oracle networks. The discussion centers on its role in resisting censorship and ensuring data availability in adversarial environments. Advancements in this technology are vital for the integrity of cross-chain communication and decentralized governance.
