Chaincode Services uses Docker to host (deploy) the chaincode without relying on any virtual machine or computer language.

What would be the main reason or best reason that Hyperledger chose containers over virtual machines?

  1. Docker provides a secured, lightweight method to sandbox chaincode execution that is not “locked down”.
  2. Docker provides a secured, lightweight method to sandbox chaincode execution that is not “locked down” but additional programming languages cannot be enabled.
  3. Docker provides a secured, lightweight method to sandbox chaincode execution that is “locked down”.
  4. Docker is fully compatible with Hyperledger and Linux with an upgrade subscription.

Answer(s): C

Explanation:

Docker provides a secured, lightweight method to sandbox chaincode execution that is "locked down" Chaincode Services uses Docker to host (deploy) the chaincode without relying on any virtual machine or computer language. Docker provides a secured, lightweight method to sandbox chaincode execution. The environment is a "locked down" and secured container, along with a set of signed base images containing secure OS and chaincode language, runtime and SDK images for Golang Additional programming languages can be enabled



Chaincode is a decentralized transactional program, running on the validating nodes. As with every chaincode, it implements the ____________in particular, Init and Invoke functions.

What does is actually implemented?

  1. SDK
  2. REST Interface
  3. EVM
  4. Chaincode interface

Answer(s): 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.

  1. Blockchain that exclusively supports PoS Consensus
  2. Permissionless blockchain
  3. Token
  4. Blockchain that exclusively supports PoW Consensus
  5. Umbrella collaboration of open source blockchains

Answer(s): E

Explanation:

hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing and Technology.
