What type of organization can be thought of as a corporation run without any human involvement under the control of an incorruptible set of business rules?

  1. Limited Liability Corporation
  2. Decentralized Autonomous Organization (DAO)
  3. Corporation
  4. Trust

Answer(s): B

Explanation:

Decentralized Autonomous Organization (DAO) can be thought of as a corporation run without any human involvement under the control of an incorruptible set of business rules. A DAO can also be seen as the most complex form of a smart contract, where the bylaws of the decentralized organization are embedded into the code of the smart contract, using complex token governance rules.



Chaincode in Hyperledger Fabric is a decentralized transactional program which is running on the validating nodes. Chaincode implements the Chaincode interface in particular, Init and Invoke functions.
Which two statements about Chaincode is correct? (Select two.)

  1. Init is called during instantiate transaction after the chaincode container has been established for the first time, allowing the chaincode to initialize its internal data
  2. Invoke is called to update or query the ledger after a proposal transaction. Update state variables are committed to the ledger before the transaction is committed
  3. Init is called during Instantiate transaction after the chaincode ledger has been established for the first time, allowing the chaincode to initialize its internal data
  4. Invoke is called to update or query the ledger in a proposal transaction. Updated state variables are not committed to the ledger until the transaction is committed.

Answer(s): A,D

Explanation:

Chaincode is a decentralized transactional program, running on the validating nodes. As with every chaincode, it implements the Chaincode interface in particular, Init and Invoke functions. Init is called during Instantiate transaction after the chaincode container has been established for the first time, allowing the chaincode to initialize its internal data. Invoke is called to update or query the ledger in a proposal transaction. Updated state variables are not committed to the ledger until the transaction is committed.



Blockchain solutions are comprised of four building blocks. Which of the following answers list the building blocks?

  1. Shared ledger, Privacy, Trust, and Smart Contracts or (Chaincode)
  2. Shared ledger, Centralization, Trustless, and Smart Contracts or (Chaincode)
  3. Shared ledger, Privacy, Trustless, and Smart Contracts or (Chaincode)
  4. Shared ledger, Centralization, Trust, and Smart Contacts or (Chaincode)

Answer(s): A



An_____________ is defined as a communication node that is responsible for the distribution of blockchain transactions in Hyperledger Fabric.

  1. MSP
  2. Peer Node
  3. Client Node
  4. Endorsing Node
  5. Orderer

Answer(s): E

Explanation:

Orderer Ordering services handles the main function of the Hyperledger Fabric to maintain consistency in the transactions processes. Ordering services provides a shared communication to clients and peers and helps in broadcasting the messages containing transactions.



The ledger system in Hyperledger Fabric uses what database by default?

  1. CouchDB
  2. LevelDB
  3. MySQL
  4. MS SQL
  5. PostGres SQL

Answer(s): B

Explanation:

The ledger system in Hyperledger fabric uses levelDB. By definition, LevelDB allows concurrent writers to safely insert data into the database by providing internal synchronization. LevelDB uses very coarse-grained synchronization which forces all writes to proceed in an ordered, first-come-first- served basis, effectively reduces throughput to a single thread. State database options include LevelDB and CouchDB. LevelDB is the default key-value state database embedded in the peer process. CouchDB is an optional alternative external state database. Like the LevelDB key-value store, CouchDB can store any binary data that is modeled in chaincode (CouchDB attachment functionality is used internally for non-JSON binary data). But as a JSON document store, CouchDB additionally enables rich query against the chaincode data, when chaincode values (e.g. assets) are modeled as JSON data
