Polymer University - Chapter 1 - Rollups Answer :
- 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

Polymer University - Chapter 3 Answer :
- The belief that interoperability must reach web2 levels of connectivity performance to enable scalable applications
- Exist across multiple layer2 rollups in order to decrease latency, cost and be more viable
- By reducing transaction costs and improving accessibility for users across different networks, it also could lead to more throughput for dApps*
- Rollup fragmentation is growing and needs to be addressed
- High latency and limited throughput of current blockchain networks
- More than 100
- Approximately 357 million times more expensive.
- Enhancing connectivity and interoperability between multiple rollups
- Connect an infinitely increasing number of on-chain building blocks
- It makes building on-chain more feasible by improving performance and reducing costs
- L2 networks are siloed, making cross-chain communication difficult
- Fragmentation leading to interoperability issues
- It allows for seamless data and asset transfers and unified liquidity across different L2s
- They allow L2s to share data and communicate seamlessly without relying on centralized bridges
- It allows users to move assets seamlessly between L2s without complicated bridging processes
- All of the Above
- Extremely Critical
- To build a unified, interconnected L2 ecosystem that operates with Ethereum’s security guarantees
