With the release of Alpha V2, Linea has slashed the costs of submitting proofs on Layer-1 by 90% compared to its predecessor, Alpha V1. These reductions are achieved through data compression mechanisms and proof aggregation.
ZK-Rollup solutions bundle transactions into batches and need to submit proofs to Layer-1 blocks concurrently. Previously, V1 only supported one batch per proof. However, with the new proof aggregation mechanism, 30 batches can now be appended to a single proof, optimizing authentication costs for the network.
Regarding transaction data compression, Linea opts to compress these inputs to minimize storage requirements on Layer-1, which typically incur significant costs.
Thanks to these changes, Linea states that gas fees for executing operations on the network will be reduced by up to 66%.

Linea is a Layer-2 solution developed by Consensys, officially deployed on the mainnet in July 2023. However, during the initial product development phase, Linea encountered various technical issues, notably the inability to support fast withdrawals for users.
