Definition ∞ Publicly verifiable output refers to any result or data generated by a system that can be independently confirmed by anyone using publicly available information and cryptographic proofs. In blockchain, this ensures that computations performed off-chain or by specific network participants are correct and tamper-proof. It underpins trust in decentralized systems without requiring reliance on a central authority.
Context ∞ Publicly verifiable output is a central concept in scaling solutions like rollups and in the development of verifiable computation. News often discusses new proof systems that enhance the efficiency or scope of what can be publicly verified. This capability is vital for maintaining transparency and security in systems that process transactions or data outside the main blockchain.
