While it appears that this question asks for an opinion, the interviewer is looking for you to state facts and the rationale behind why blockchains are secure. When asked to provide an opinion, you can feel free to do so as long as it is well-grounded in factual data. Any opinion you provide should also align with those of the organization with whom you are interviewing.

"There are several different reasons why a blockchain is a trusted approach to financial transactions. These include it being open-sourced and therefore compatible with other business applications and the fact that it is transparent and secure due to its distributed nature. Blockchains improve the efficiency and speed of transactions, and they are hack-proof based on the fact that there is no central authority that controls them."
