📖 Charpter 2 - Ecosystem and Landscape

🧑‍🤝‍🧑 Major players

Optimistic Rollup

  • Optimism
  • Arbitrum

ZK Rollup

  • ZKSync
  • STARK WARE

💰 Layer2 - Capital

🅾️ Optimism

  • First rollup solution, OG Team from Palasma project
  • Only big protocols allowed in the beginning (SNX, UNI)
  • Centralized, users need to trust OP.
  • OP token distributed, not too successful
  • 20 Million OP token lost

🇦 Arbitrum

  • A modiefied version of OP
  • L2 TVL no 1
  • OWN AVM impelementation for fast Proof Check replay, auto translate EVM code to AVM
  • Multi-round interactive rollup
  • Arbitrum Odyssey - airdrop confirmed?

🇿 ZKSYNC

  • SNARK zero knowledge proof
  • ZKSYNC 2.0 alpha testnet REDSHIFT + EVM compatible

✨ StarkWare

ZK-STARK

  • Require No trusted setup
  • Quantum Resistance
  • Ethereum Foundation Support 12M grants
  • Require complex math in the algorithm

⚔️ ZK-STARK vs ZK-SNARK

✨ StarkWare Ecosystem

  • dydx
  • Immutable X
  • Sorare
  • DeversiFi
  • Myria

✨ StarkEx

StarkEx is a permissioned tailor-made scaling engine, designed by StarkWare to fit the specific needs of apps.

✨ StarkNet

StarkNet is a permissionless decentralized ZK-Rollup. It operates as an L2 network over Ethereum, enabling any dApp to achieve unlimited scale for its computation – without compromising Ethereum's composability and security.

💻 StarkNet Development

  • Cairo, python like language to fully utilize STARK
  • Not EVM compatible
  • Solidity to Cairo Transpiler (warp)
  • Tooling is at infancy. OpenZeppelin on board

🆚 L2 Challenges

  • Composibility
  • Fracture Liquidity
  • Competitions with other chains and sidechains

🔥 Debate and disccusion

One million dollar question? Which L2 solution you prefer???
