Zero-knowledge (ZK) proof solutions have played a crucial role in the Ethereum ecosystem’s scalability, but Consensys’ zkEVM Linea head, Nicolas Liochon, anticipates that proto-danksharding will bring about a significant reduction in rollup costs.
During Korea Blockchain Week, in an exclusive conversation with Cointelegraph Magazine editor Andrew Fenton, Liochon projected that proto-danksharding, also known as Ethereum Improvement Proposal (EIP) EIP-4844, could potentially slash rollup costs by tenfold.
EIP-4844 aims to address the cost issues associated with rollups, a technology that aggregates transactions and data off-chain while providing computational proof to the Ethereum blockchain.
However, the Ethereum Foundation has yet to announce a specific launch date for proto-danksharding, as development and testing continue.
Liochon explained that Linea already offers transactions 15 times cheaper than Ethereum’s layer 1, but rollups are constrained because transactions are posted in call data within Ethereum blocks.
According to Ethereum’s documentation, rollups remain expensive due to the fact that all Ethereum nodes process call data, which is stored on-chain indefinitely, despite its short-term relevance.

EIP-4844 introduces data blocks that can be sent and attached to Ethereum blocks, with the data stored within these blocks inaccessible to the Ethereum Virtual Machine, and set to be deleted after a specified timeframe.
This innovation is expected to substantially reduce transaction costs, addressing the core issue of data availability, which accounts for 95% of rollup costs.
Liochon emphasized that Linea’s prover, responsible for off-chain computation, verification, bundling, and cryptographic proof generation for combined transactions, comprises only a fifth of the overall cost.
This highlights the significant challenge in making ZK-rollups the preferred scaling solution for Ethereum over alternatives like Optimistic Rollups.
Furthermore, Linea aspires to be a versatile ZK-rollup suitable for various decentralized applications and solutions within the Ethereum ecosystem, catering to DeFi, gaming, and social applications.
Consensys successfully launched Linea in August 2023, with more than 150 partners onboarded and over $26 million in Ether bridged, as previously reported by Cointelegraph.
