I am practicing Hyperledger. This is one of the top listed blockchains. This architecture follows R3 Corda specifications. Sharing the interview questions with you that I have prepared for my interview.
Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly.
The below set of interview questions help you like a tutorial on Hyperledger fabric.
1). What are Nodes?
In Hyperledger the communication entities are called Nodes.
2). What are the three different types of Nodes?
- Client Node
- Peer Node
- Order Node
The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.
3). What is Channel?
A channel in Hyperledger is the subnet of the main blockchain. You can have n number of Channels in a Blockchain.
4). Can a Peer or Node be a part of many channels?
Yes, can be part of many channels.
5). Can the transactions within a Subnet visible to the public?
No, these are visible to people for subscribers of the particular Channel.
