  1. FALSE
  2. TRUE

How does a client app communicate with Hyperledger fabric chaincode (Smart Contracts)?

  1. The app uses an SDK which invokes functionality on the chaincode which then announces the transaction to any peers required to endorse the transaction
  2. The app uses Hyperledger Composer to communicate with CouchDB which in turn invokes chaincode functionality
  3. Client apps don’t communicate with Hyperledger fabric directly, they must use Hyperledger Composer for the transmission
  4. The app points to a node’s IP address, then calls an invoke function on the chaincode address to start the write process

Answer(s): A



On the Ethereum blockchain the “nonce” of a transaction:

  1. Holds the gas amount to be paid to the miner writing the block that contains the transaction
  2. Is used to ensure that transactions by a given account are written in sequential order
  3. Is reset to zero after each successfully mined blocked
  4. Must always start with four zeroes

Answer(s): B

  3. Have sufficient gas to perform read and write operations against the Smart Contract
  4. All of the above
