This article presents a method combining cryptographic hashing and the Ethereum blockchain to ensure data integrity: by computing a dataset's hash and writing it to the Ethereum testnet's transaction input field, creating an immutable, verifiable data fingerprint record at a cost of approximately $0.04 to $0.10 per transaction.
入选理由：使用SHA-256等加密哈希函数生成数据集的唯一指纹，确保任何微小改动都会导致哈希值完全不同。
