Nicolas Liochon, head of zkEVM Linea at Consensys, said in an interview during Korea Blockchain Week that proto-danksharding, also known as Ethereum Improvement Proposal EIP-4844, has the potential to cut rollup costs by more than 90%.
Liochon explained that the transaction cost on Linea is only equivalent to 1/15 of the cost on Ethereum L1, but the rollup cost is still higher. EIP-4844 introduces data blocks that can be sent and appended to Ethereum blocks, where the data stored is inaccessible to the Ethereum Virtual Machine (EVM) and set to be deleted after a specified period of time.
This innovation is expected to significantly reduce transaction costs and solve the core problem of data availability, which accounts for 95% of Rollup costs.
Liochon emphasized that Linea’s Prover is responsible for off-chain calculation, verification, bundling, and generation of cryptographic proofs of combined transactions, which account for only 20% of the total cost.
In addition, Linea hopes to be a versatile zkRollup for various DApps and solutions in the Ethereum ecosystem to meet the needs of DeFi, gaming, and social applications.
