Question restatement: 位置14的问题 Cryptography in blockchain is primarily used for maintaining confidentiality and for transaction verification.TrueFalse

Option 1: True. This option asserts that cryptography's main role in blockchain is both confidentiality and transaction verification. While cryptography enables verification through digital signatures, hash functions, and public-key cryptography, its primary emphasis in most blockchain designs is not confidentiality. Public blockchains are typically pseudonymous rather than confidential; anyone can see the transaction history, so confidentiality is not guaranteed by default. The cryptographic tools primarily ensure integrity, authenticity, and non-repudiation, as well as enabling tamper-evidence and consensus.

Option 2: False. This option states that the claim in Option 1 is not accurate. The core cryptographic functions in blockchain indeed provide transaction verification (via digital signatures and consensus-ensured integrity) and data integrity (hashing and linking blocks). However, confidentiality is not the central or intrinsic feature of typical blockchain systems; confidentiality would require additional privacy techniques or layers (such as private networks, encryption-at-rest, or advanced privacy protocols), which are not inherent to the basic design. Therefore, the statement in Option 1 overstates confidentiality as a primary use and misrepresents the typical emphasis of blockchain cryptography. In other words, while cryptography supports verification and integrity, confidentiality is not the primary or universal default goal across standard blockchains.

Overall, the analysis highlights that cryptography in blockchain is best understood as providing verification, integrity, and non-repudiation, with confidentiality being secondary or context-dependent depending on the specific blockchain implementation and privacy features.
