What is true about the historic states in Hyperledger Fabric model?

AThey can be modified by anyone with write access.

BAdministrator role is required for access.

DThey cannot be accessed by anyone.

Show Suggested Answer

Suggested Answer: C

In Hyperledger Fabric, the standard possibilities to configure parameters of a component, such as a peer or orderer, include using YAML configuration files, environment variables, and command-line interface (CLI) flags. This approach provides flexibility and allows for detailed control over the parameters that govern the behavior of these components .

Yeah, but anyone can view them, just not modify!

Wait, are you sure about that? I thought they could be modified.

I’m a bit confused; I thought historic states could be accessed by anyone with the right permissions, but now I’m not so sure.

I practiced a similar question about state access in Hyperledger, and I feel like option C makes the most sense since they should be unchangeable.

I remember something about how only admins can modify certain states, but I can't recall if that applies to historic states too.

I think historic states are supposed to be immutable, but I'm not completely sure if that's the right term.

Wait, I'm a bit confused. I thought the states in Fabric could be modified, but maybe that's only for the current state. I'll have to think this through carefully before selecting an answer.

Okay, I've got a good feeling about this one. The historic states in Hyperledger Fabric are immutable, so I'm pretty confident that option C is the correct answer.

Hmm, this one seems a bit tricky. I'm not 100% sure about the details of historic states in Fabric, but I'll give it my best shot and try to eliminate the options that don't sound right.

I think the key here is to focus on the concept of "historic states" in Hyperledger Fabric. The question is asking about their properties, so I'll need to recall what I know about how state is managed in this blockchain framework.

Wait, so you're telling me the historic states in Hyperledger Fabric are like the holy grail of blockchain data? Untouchable, immutable, and only accessible to the chosen ones? Sign me up for that blockchain party!

A) They can be modified by anyone with write access? Haha, that's a joke, right? If anyone could modify the historic states, it would be the perfect recipe for disaster. No way that's the correct answer.

B) Administrator role is required for access? Seriously? I thought the whole point of blockchain was decentralization. Why would we need an administrator to access the historic states?

C) They are immutable? That's the only logical answer here. Why would anyone be able to modify the historic states in a Hyperledger Fabric model? That defeats the whole purpose of the blockchain!
