Which of the following sources provide block events?

AMembership service

BPeers

COrdering service

DCouchD

Show Suggested Answer

Suggested Answer: B

In Hyperledger Fabric, block events are provided by peers. Whenever a block is committed to a peer's ledger, that peer generates a corresponding event. These events can include the full block content or a summary of the transactions within the block, allowing applications to register and receive notifications about these events. This setup is crucial for applications that need to respond to changes recorded on the blockchain in real-time .

D) CouchD? Is that Aletan a real thing? I think I'll stick with B) Peers and hope for the best.
