Ethereum's Proto-Danksharding Set to Drastically Cut Roll-Up Costs, Says Consensys' zkEVM Linea Head
Summary:
Proto-danksharding is expected to greatly reduce the cost of roll ups in the Ethereum ecosystem, potentially lowering them by 10 times, according to Consensys’ zkEVM Linea head Nicolas Liochon. This improvement proposal aims to decrease expenses by introducing data blocks and reducing transaction costs. Linea, a general-use ZK-rollup, offers cheaper transactions compared to Ethereum's layer one. The Ethereum Foundation is still working on developing and testing proto-danksharding for an undisclosed launch date.
Zero-knowledge proof (ZK-proofs) solutions have played a crucial role in scaling the Ethereum ecosystem. However, according to Nicolas Liochon, the head of Consensys' zkEVM Linea, proto-danksharding is expected to significantly reduce the cost of roll ups. During an exclusive interview with Cointelegraph Magazine, Liochon estimated that proto-danksharding could lower rollup costs by 10 times. The aim of proto-danksharding, also known as EIP-4844, is to decrease the expenses associated with rollups, which involve off-chain transaction and data batching along with submitting computational proof to the Ethereum blockchain. The Ethereum Foundation is still working on developing and testing proto-danksharding, and an expected launch date has yet to be determined. Liochon explained that Linea transactions are 15 times cheaper than those on Ethereum's layer one, but rollups are limited by the fact that transactions are posted in calldata in Ethereum blocks. According to Ethereum's documentation, rollups are costly because calldata is processed by all Ethereum nodes and the data is stored on-chain indefinitely, even though it only needs to be available for a short period. With the introduction of EIP-4844, data blocks can be sent and attached to blocks, allowing for reduced transaction costs. Liochon emphasized that the cost of rollups primarily depends on data availability, with data storage on layer one accounting for 95% of the cost. He also noted that Linea's prover, which handles off-chain computation and creates cryptographic proofs, only accounts for a fifth of the cost. This highlights the challenge in making ZK-rollups the preferred scaling solution for Ethereum, compared to alternatives like Optimistic rollups. In addition, Linea aims to be a general-use ZK-rollup, supporting various decentralized applications and solutions within the Ethereum ecosystem, including DeFi, gaming, and social platforms. Consensys successfully launched Linea in August 2023, onboarding over 150 partners and facilitating more than $26 million worth of ETH transactions.
