Modular Blockchains & Tokenomics Quiz

Which layer in the Modular Blockchain stack, specialized by projects like Celestia, addresses the primary scalability bottleneck for rollups by making transaction data cheap and easily verifiable?

• Execution Layer

• Consensus Layer

• Data Availability (DA) Layer

• Settlement Layer

Ethereum's Dencun upgrade (EIP-4844) introduced 'blobs' to the network. What is the primary purpose of these blobs in the context of Layer 2 (L2) scaling?

• To facilitate the immediate, trustless conversion of L2 tokens back to Layer 1 (L1) tokens.

• To act as a separate, cheaper, temporary storage layer for L2 transaction data, rather than permanent storage in CALLDATA.

• To execute complex zero-knowledge proofs off-chain before submitting them to L1.

• To enable the use of non-EVM compliant execution environments on L2s.

The core difference in finality between ZK-Rollups and Optimistic Rollups is that ZK-Rollups post a cryptographic proof for every batch. What is this proof called?

• Proof-of-Work (PoW)

• Fraud Proof

• Validity Proof

• Proof-of-Stake (PoS)

Which concept, when applied to a ZK-EVM (Zero-Knowledge Ethereum Virtual Machine), denotes the highest level of compatibility, aiming to be exactly equivalent to the Ethereum mainnet at the consensus client level?

• Type 4: Language-level Equivalence

• Type 3: Bytecode Equivalence

• Type 2: Execution-level Equivalence

• Type 1: Full Ethereum Equivalence

Layer 3s (L3s), such as those proposed using Arbitrum Orbit or Starknet, aim to primarily improve upon L2s in what specific area?

• Greater network decentralization at the validator level.

• Application-specific customization, hyper-scaling, and tailored fee markets.

• Directly replacing the need for the Layer 1 settlement layer.

• Providing native liquidity pooling for all cross-chain assets.

What specific mechanism does a project like Celestia use to allow 'light nodes' to ensure the Data Availability of a large block without requiring them to download the entire block?

• Proof-of-Historical State (PoHS)

• Data Availability Sampling (DAS)

• Recursive SNARKs

• Inter-Blockchain Communication (IBC) Protocol

Which term describes a blockchain's inability to increase its block size indefinitely due to the constraint that full nodes must download and process all transaction data, leading to centralization?

• Data Fragmentation

• The Trilemma Fallacy

• The Data Availability Bottleneck

• Execution Latency

Solana's proposed Firedancer upgrade is primarily designed to address which aspect of the network?

• Implementing ZK-proofs for faster cross-chain transactions.

• Introducing an EVM-compatible execution environment.

• Improving validator client diversity and significantly increasing network throughput.

• Enabling native Liquid Staking Derivatives (LSDs).

What is the foundational principle behind EigenLayer's Restaking mechanism?

• It converts Liquid Staking Tokens (LSTs) directly into Real-World Assets (RWA).

• It creates a new consensus layer using Proof-of-Work (PoW) on top of Ethereum.

• It leverages Ethereum's staked $ETH security and economic collateral to secure external protocols (Actively Validated Services, or AVSs).

• It allows L2 transaction fees to be paid directly in $ETH.

Liquid Restaking Tokens (LRTs) like ezETH or rsETH offer a key advantage over direct restaking. What is it?

• They eliminate all smart contract risk for the user.

• They provide instant liquidity for the restaked position, allowing its use in DeFi (composability).

• They guarantee that the user will not face any slashing penalties.

• They only accept $wBTC as collateral, not $ETH.
