How Do ‘Layer 2 Scaling Solutions’ Aim to Alleviate Mempool Congestion?
Layer 2 solutions, such as Rollups (Optimistic and ZK), process transactions off the main blockchain (Layer 1) and then batch the results back to L1 in a single transaction. This significantly reduces the load on the L1 Mempool.
By processing thousands of transactions for the cost of one L1 transaction, they lower overall fees and increase throughput, effectively alleviating congestion.
