Triple

Target class: zero-knowledge proof system
Context triple: [zk-SNARKs, instanceOf, zero-knowledge proof system]

• A. cryptographic voting system
  A cryptographic voting system is a secure, privacy-preserving election mechanism that uses cryptographic protocols to ensure ballot secrecy, voter authentication, integrity of tallies, and verifiable results without revealing individual votes.
• B. proof-of-work system
  A proof-of-work system is a consensus mechanism in which participants must perform and verifiably demonstrate computationally expensive work to gain the right to add new records or blocks, thereby securing the system against abuse.
• C. cryptographic protocol chosen
  A cryptographic protocol is a precisely defined sequence of operations and message exchanges that uses cryptographic primitives to achieve security goals such as confidentiality, integrity, authentication, and non-repudiation between parties.
• D. cryptographic protocol component
  A cryptographic protocol component is a modular element—such as a key exchange, authentication step, or encryption mechanism—that participates in a larger protocol to provide specific security properties like confidentiality, integrity, or authenticity.
• E. cryptographic primitive
  A cryptographic primitive is a low-level, well-defined algorithm or protocol (such as a hash function, block cipher, or digital signature scheme) that serves as a basic building block for constructing more complex cryptographic systems and protocols.
• F. None of above.
