UnverifiedGit采用基于内容的SHA-1哈希值的内容寻址存储模型，每次提交都会生成哈希，任何改动都会产生不同哈希79% similarUnverifiedUsing a content hash (such as a commit SHA) as the cache key ensures that analysis results for the same version of code are consistent and reusable.72% similarVerifiedGit uses the SHA-1 hash function to map input data of arbitrary length to a fixed 160-bit (40 hexadecimal character) hash value as the object identifier.70% similarUnverified通过对系统提示内容生成 SHA-256 等哈希值并公开，用户可在不获取明文的前提下验证提示词版本未被篡改62% similarUnverifiedThe self-describing nature of Multihash means that when upgrading the hash algorithm from SHA-256 to SHA-3, identifiers for existing data can still be correctly parsed without ambiguity.60% similar
