I thought edge computing was more about processing data closer to the source, not really about creating ledgers. I’m leaning towards encryption, but I’m not entirely sure.

I vaguely remember a practice question about the role of encryption in blockchain. It seems like it could be the right answer, but I'm not completely confident.

I feel like we discussed how blockchain relies on distributed systems, but I can't recall if that directly ties to any of these options.

I'm a little stumped on this question. Blockchain involves a lot of different technologies, and I'm not sure if encryption is the primary one used to create the distributed ledger. I'll have to review my notes and try to eliminate the other options.

Encryption makes the most sense to me. Blockchain uses cryptographic techniques to validate transactions and maintain the integrity of the distributed ledger. I feel pretty confident about this one.

Okay, let me break this down. Blockchain is all about decentralization and security, so I'm guessing the answer has to do with one of the core technologies that enables that. Encryption seems like a good bet, but I'm not 100% certain.

Hmm, I'm a bit confused on this one. I know blockchain has something to do with distributed computing, but I'm not sure if encryption is the primary mechanism used. I'll have to think this through more carefully.

Haha, good one! Clearly the answer is D. Encryption. Unless the blockchain is running on a quantum computer...then it's anyone's guess!
