✳️A foundational level of blockchain architecture, operating as the primary and autonomous chain on which transactions are directly executed and confirmed

✳️A network built on top of Ethereum that enhances scalability by processing transactions off-chain before settling on the mainnet

✳️A decentralized Layer 1 network that supports smart contracts, security, and a thriving ecosystem of decentralized applications (dApps)

✳️An application-focused and driven network

✳️Ethereum should serve as a secure settlement layer while rollups and Layer 2 solutions handle execution and customization

✳️The App-Chain Thesis

✳️ All of the above

✳️Scalability

✳️Rollups

✳️ No, Other types of Layer2 networks include State Channels, Plasma and Validiums

✳️A Layer2 network built on Ethereum that bundles multiple transactions into a single batch for efficiency

✳️By processing transactions off-chain and settling them on Ethereum, reducing execution costs and load on Layer 1

✳️ They process transactions off-chain, reducing congestion and lowering costs on the main blockchain

✳️Optimistic and Zero-Knowledge (ZK) rollups

✳️ They assume all transactions are valid by default and allow for fraud proofs to challenge invalid transactions

✳️ By using zero-knowledge proofs to validate transactions off-chain and submitting a succinct proof to the main chain

✳️ Lack of inter-L2 connectivity

✳️ Fragmented and insecure interoperability solutions

✳️ Yes

Polymer University - Chapter 2 Answer :

- High transaction costs and network congestion

- By executing transactions off-chain and posting data on-chain

- To enhance scalability and reduce transaction costs

- An entity responsible for ordering and batching transactions

- To achieve higher throughput and lower transaction costs

- By making the network more scalable and cost-effective

- They are a fundamental part of Ethereum’s scaling vision, working alongside sharding for long-term scalability

- Ability to customize their app and and control their own costs and revenue

- Rollups will handle most execution while Ethereum remains a secure settlement layer

- By posting transaction data back to the Ethereum mainnet

- TVL (Total Value Locked)

- The total value of assets (cryptocurrencies) staked, deposited, or locked in a protocol

- It reflects the chain's ability to support and attract decentralized applications (dApps) and shows user trust and activity.

- Ethereum (EVM) Rollups

- 30%

- The Superchain

- A decentralized network of interconnected rollups that share security, liquidity, and tooling

- Rollups - Arbitrum, Base and Optimism

- Rollups

- Extremely Important
