A development team is designing a permissioned blockchain for a financial consortium that requires very fast transaction finality and can tolerate a small number of known, trusted validators. The system must be able to withstand up to one-third of these validators failing or acting maliciously. Which specific consensus algorithm fits these requirements best?
Answer: B. Practical Byzantine Fault Tolerance (PBFT)
Practical Byzantine Fault Tolerance (PBFT) is a consensus algorithm designed for distributed systems that provides high performance, low latency, and deterministic finality. It is particularly well-suited for permissioned networks with a known, limited number of validators. A key feature of PBFT is its ability to reach consensus and guarantee correctness as long as fewer than one-third of the nodes are Byzantine (malicious or faulty).
A developer needs a local blockchain environment for rapid development, testing, and debugging of Ethereum smart contracts. This environment should offer features like stack traces for Solidity, mainnet forking, and a rich plugin ecosystem. Which development framework best fits these requirements?
Answer: D. Hardhat
Hardhat is a professional development environment for Ethereum that provides a flexible and extensible framework for testing, deploying, and debugging smart contracts. Its key features include the Hardhat Network (a local Ethereum network), detailed stack traces for Solidity, mainnet forking capabilities, and a vast ecosystem of plugins, making it ideal for complex development workflows. Remix is a browser-based IDE, Ganache is a local blockchain GUI, and OpenZeppelin provides secure contract libraries, but Hardhat is the comprehensive development environment that meets all the specified criteria.
Which technique helps protect against front-running by hiding transaction intent until confirmation?
Answer: A. Commit-reveal scheme
Commit-reveal first submits a hashed commitment, then reveals the value later, hiding intent from front-runners.
What does a VRF (Verifiable Random Function) provide in consensus protocols like Algorand?
Answer: B. Unpredictable yet verifiable random leader selection
A VRF generates randomness that is unpredictable in advance but publicly verifiable afterward, used for secret committee selection.
