Key Highlights of the Episode

Importance of L2 Considering Historical Presence

  • In the past, Ethereum faced challenges due to high costs on its mainnet for activities like NFT minting and trading.
  • L2s emerged as an experimental solution to expand and create a separate execution layer.
  • Over time, L2s, particularly roll-ups, have become critical to Ethereum’s scaling roadmap.
  • L2s offer a more cost-effective and efficient alternative for retail users than Ethereum’s mainnet.
  • L2s are now considered the core user product for Ethereum, offering a broader ecosystem and lower costs for various activities.

Benefits of ZK L2s Over Other L2s

  • ZK roll-ups are utilized for scaling to enhance speed and reduce costs.
  • They use mathematical safety guarantees, providing a simpler and faster execution process.
  • Unlike some other chains, ZK roll-ups focus primarily on scaling rather than privacy.
  • They offer a more efficient approach to compressing transactions and validating actions on Ethereum.

Traction and Benchmarks Updates of Scroll

  • Scroll has achieved significant Total Value Locked (TVL) figures in DeFi, surpassing other ZK L2s.
  • Recent developments include becoming the first ZK roll-up to receive an award and aiming to integrate with Compound.
  • Upcoming upgrades, like the Dencun upgrade, are expected to reduce transaction costs by up to 10x drastically.
  • The project is pioneering a multi-proof approach for enhanced fault tolerance and client diversity.

Dencun in L2

  • Dencun is a hard fork update for L2s aimed at reducing transaction gas fees by 3–5x.
  • It contributes to the narrative of roll-ups being the preferred choice for users due to their efficiency.

Privacy in ZK L2

  • While privacy features are currently limited in L2s, there’s a growing emphasis on security.
  • As a security-minded L2, Scroll prioritizes utilizing ZK for security rather than privacy.
  • However, privacy remains crucial for future developments as the industry matures.

Future Prospects for ZK L2

  • Scroll aims to expand its ecosystem through restaking mechanisms, enhancing the DeFi space, and focusing on user rights and experience.
  • Users can restake Scroll tokens to gain liquidity and yield, simplifying the process through native restaking providers.
  • Collaboration with other ZK teams is encouraged for further development and innovation in the space.

Call to Action Within a Few Weeks

  • Scroll encourages collaboration with researchers, protocol developers, and anyone building in the ZK space.
  • Stay tuned for upcoming upgrades and technological advancements, including data compression and multi-proof systems.

Future Projects

  • ZK technology offers diverse applications ranging from protocol-level implementations to hardware engineering.
  • Libraries and ZK roll-up toolkits vary based on specific team preferences and technologies, such as Aztec or Scroll.
