Retroalimentación Solución Correcto Incorrecto Correcto Incorrecto Pregunta How does the hashing algorithm contribute to the formation of a chronological chain of records in a blockchain? (Select all that apply) Respuestas Opción 1 By encrypting the transaction data to prevent unauthorized access. Opción 2 By generating a unique digital signature for each user. Opción 3 By randomly assigning blocks to different places in the chain to increase security. Opción 4 By creating a unique hash for each block that includes the hash of the previous block, linking them together. Retroalimentación Solución Incorrecto Incorrecto Incorrecto Correcto Pregunta What is the impact on the blockchain if a previous block's data is altered? (Select all that apply) Respuestas Opción 1 The change goes unnoticed, maintaining the blockchain's integrity. Opción 2 Only the altered block's hash changes, without affecting the rest of the chain. Opción 3 The hash of the altered block changes, which in turn invalidates all subsequent block hashes, disrupting the chain's integrity. Opción 4 The blockchain automatically corrects the alteration, restoring the original data.
