Question

Which of the following statements regarding the features of blockchain technology are correct? 1. Records may be made visible to relevant stakeholders without risk of alteration. 2. Copies of the entire database are stored on multiple computers, syncing within seconds. 3. Consortium blockchain is a blend of public and private blockchains allowing selective data access. 4. Mathematical algorithms make it impossible to change or delete any data once recorded and accepted.

Accepted Answer

All four statements are factually correct about blockchain principles. Option C (1, 2, and 4) is the most comprehensive available answer as no option includes all four. Statement 3 is also correct — consortium blockchain is a semi-decentralized hybrid model — but the answer key identifies C as correct since no option captures all four.
