Ethereum Needs Polygon's Aggregation Layer to Scale

As more and more L2s launch promising to scale Ethereum, they end up competing for the same market share, userbase and liquidity. Apart from this harsh reality, crosschain interactions should be as seamless as possible in order to bridge different L2 ecosystems. Polygon envisions a scalable future in which various zero knowledge rollups post their proofs on an aggregation layer before settling on Ethereum, thus lowering latency and transaction costs as crosschain interactions take place expeditiously, without involving the L1 mainnet.

We were joined by Sandeep Nailwal & Brendan Farmer, to discuss Polygon’s aggregation layer and how it aims to solve the current fragmentation of Ethereum L2 scaling solutions.

Topics:

• Polygon’s ZK expansion and the acquisition of Mir Protocol
• Polygon’s aggregation layer
• Block building between different L2s
• Shared sequencing & asynchronous sequencing
• Security guarantees of the aggregation layer
• Sequencer decentralisation & censorship resistance
• Chains using Polygon’s aggregation layer
• Pessimistic proofs
• Can optimistic rollups be included in the aggregation layer?
• Type 1 prover and Plonky3
• The evolution of ZKP systems
• Ensuring ZK rollup integrity
• The future of scalability
