In a distributed ledger system, which mechanism ensures a miner's proposed block is valid without revealing the block's contents to every node on the network?

💡 Explanation

Zero-knowledge proofs allow a prover to convince a verifier that a statement is true without revealing any information beyond the validity of the statement; because the miner can prove the block is valid without revealing its contents, the network can verify the integrity without compromising confidentiality; therefore, zero-knowledge proofs provide validity rather than simply relying on network synchronization or fault tolerance.
