The State of Second Layer (L2) Blockchain Scaling Solutions

Which blockchain scaling solutions can be used right now? What tradeoffs do they make? What can we expect in the near future? In this session, Aron van Ammers, CTO and co-founder of Outlier Ventures, reviews the current state of second layer (L2) blockchain scaling solutions.

Over the past few months, transaction fees on the top two public blockchains (Bitcoin and Ethereum) have risen sharply, along with the growth of DeFi protocols.

Various forms of the second layer scaling solutions have been proposed to increase blockchain processing capacity. Will these solutions help, and when?

Aron van Ammers reviews all of the most popular L2 scaling solutions, including:

  • State channels
  • Sidechains
  • Optimistic rollups
  • ZK rollups
  • ETH 2.0
  • Bitcoin Lightning and Liquid
