Question 1

In Hyperledger Fabric, what distinguishes 'chaincode' from traditional smart contracts on public blockchains?

Accepted Answer

Chaincode is executed in a sandboxed Docker container and can be written in multiple languages

Answer

Hyperledger Fabric chaincode runs inside Docker containers and supports languages like Go, Java, and Node.js, unlike most public blockchain smart contracts limited to a single language.

Question 2

Which enterprise blockchain platform uses the concept of 'CorDapps' as its application layer?

Accepted Answer

R3 Corda

Answer

CorDapps (Corda Distributed Applications) are the application layer on R3 Corda that define flows, states, and contracts for specific business processes.

Question 3

What is the key privacy advantage of R3 Corda compared to traditional blockchain networks?

Accepted Answer

Transaction data is shared only with parties directly involved in the transaction

Answer

Corda's architecture shares transaction data only with the parties directly involved, unlike most blockchains that broadcast data to all participants.

Question 4

In an enterprise blockchain deployment, what does 'BFT' stand for and why is it significant?

Accepted Answer

Byzantine Fault Tolerance, ensuring the network operates correctly even with malicious nodes

Answer

Byzantine Fault Tolerance (BFT) ensures a blockchain network can reach consensus even if some nodes behave maliciously, which is critical for untrusted multi-party enterprise networks.

Question 5
