question 54

Multiple Choice

Consider the following scenario: A solo app developer wants to create their own cryptocurrency and build a blockchain based that allows users to buy and sell second-hand items with that cryptocurrency from each other.

Which architecture would best solve the product need?

• B) Ethereum for token creation; Traditional multitier API and database for escrow service; User-facing features built in web technologies then minified unto a String and deployed to an Ethereum Smart Contract
• C) Hyperledger Fabric for the escrow service and token creation using chaincode; User-facing features built with Hyperledger Composer
• D) The product cannot be built. Fully decentralized apps are not yet possible for user interface
