Question

BlackTom AI · Accepted Answer

The question asks about hash functions in blockchain and whether they are designed to be easily reversible.
Option 1: 'True' — If hash functions were easily reversible, it would be trivial to recover the input from the output. In blockchain and cryptography, hash functions are intentionally designed to be one-way, meaning they should be easy to compute in one direction but hard to reverse. Therefore this statement contradicts the fundamental property of cryptographic hash functions, making it incorrect.
Option 2: 'False' — This aligns with the core principle of cryptographic hashes used in blockchain: they are designed to be one-way and preimage resistant. While they are fast to compute for legitimate purposes, reversing the hash to obtain the original input is computationally infeasible, which is essential for security.
In summary, the idea that hash functions are easily reversible is inconsistent with how blockchain relies on cryptographic hashes for integrity and security, so the false option correctly captures this concept.
