  • Increased transaction speed
• Recent Developments:
  • Mainnet launch in 2023
  • Seamless integration with Ethereum

Polygon (formerly Matic Network)

• Context: Polygon offers a multi-chain scaling solution that enhances blockchain application development through sidechains and layer 2 scaling technologies.
• Benefits:
  • Faster transaction times
  • Lower fees compared to Ethereum
• Recent Developments:
  • Integration with major DeFi platforms in 2022

Arbitrum

• Context: Arbitrum is another successful Layer 2 solution utilizing optimistic rollups to scale Ethereum transactions securely off-chain.
• Benefits:
  • Reduced gas costs
  • Increased transaction speed
• Recent Developments:
  • Launch of Arbitrum One mainnet in 2023

Binance Smart Chain (BSC)

• Context: BSC, developed by Binance, supports smart contracts and integrates various Layer 2 solutions for enhanced scalability.
• Benefits:
  • Faster transaction times
  • Lower fees compared to Ethereum
    -Recent Developments: Introducing its own version of Layer 2 scaling solutions in 2022.

Potential Fallout of Layer 2 Solutions:
