Layer2. Does it work?

We’ve launched a new series of online meetups focused on decentralized web, the Ethereum ecosystem, and DeFi. The first meetup covered one of the most pressing topics today—Ethereum scalability. Andrey Sobol from Matter Labs shared insights on the current state of Layer 2 scaling solutions.

Key topics:

• 🔹 Why do we even need Layer 2? 🔍
• 🔹 Breakdown of major solutions: sidechains, state channels, plasma, optimistic rollups, zk-rollups, and validiums.
• 🔹 Weak points of each approach.
• 🔹 Why is Plasma dead? 🪦
• 🔹 Layer 2 limitations and scalability ceilings.
• 🔹 How zk-Porter by Matter Labs tackles the problem with a hybrid approach.
• 🔹 The concept of sharding and its risks.
• 🔹 What will happen to Ethereum after the transition to PoS and EIP-1559?
