解读问题：在区块链中，密码学是否同时确保交易数据的安全性与参与者用户身份的真实性？选项为 True 或 False。
选项 True（正确的判断）在于：区块链广泛使用公钥密码学、私钥签名和哈希函数来保护数据的机密性、完整性与不可抵赖性。具体来说，交易通过私钥签名来证明发起者的身份，并由公钥或地址进行验证，确保签名与对应的用户确实参与了交易；同时，哈希链和共识机制确保数据在区块中不可被篡改，提升整体安全性。换言之，密码学不仅保护数据内容，也提供对交易发起者身份的认证能力。
对于错误选项的处理：
- 选项 False：若认为区块链仅保护数据不涉及身份真实性，忽略了数字签名和公钥基础设施等认证机制，这是对实际技术方案的误解，因为身份验证是通过私钥签名和公钥对应关系来实现的。
- 其他模糊或极端断言通常会混淆安全性与隐私的边界，或者错误地将身份认证排除在密码学功能之外，这都是对区块链设计的偏离理解。
总结而言，区块链中的密码学机制同时支撑了数据的安全性和用户身份的真实性，与题干陈述一致，因此正确地理解应包含两方面的保障。
