Ethereum’s proto-danksharding to make rollups 10x cheaper — Consensys zkEVM Linea head

Zero-knowledge impervious (ZK-proofs) solutions person proved captious successful helping standard the Ethereum ecosystem, but proto-danksharding is expected to drastically trim the outgo of rotation ups according to Consensys’ zkEVM Linea caput Nicolas Liochon.

Speaking exclusively to Cointelegraph Magazine exertion Andrew Fenton during Korea Blockchain Week, Liochon estimated that proto-danksharding could further trim rollup costs by 10 times.

Proto-danksharding, besides known by its betterment connection identifier EIP-4844, is aimed astatine reducing the outgo for rollups, which typically batch transactions and information off-chain and taxable computational impervious to the Ethereum blockchain.

The Ethereum Foundation is yet to nail down an expected motorboat information for proto-danksharding but improvement and investigating is inactive ongoing. 

As Liochon explained, Linea delivers 15 times cheaper transactions compared to those made connected Ethereum’s furniture one, but rollups are inactive constricted by the information that transactions are posted successful calldata successful Ethereum blocks.

According to Ethereum’s documentation, rollups are inactive costly successful presumption of their imaginable due to the fact that calldata is processed by each Ethereum nodes and the information is stored connected concatenation indefinitely contempt the information that the information lone needs to beryllium disposable for abbreviated period.

EIP-4844 volition present information blocks that tin beryllium sent and attached to blocks. The information stored successful blobs is not accessible to the Ethereum Virtual Machine and volition beryllium deleted aft a definite clip play - which is touted to drastically trim transaction costs.

“In reality, the outgo of rollups is down to information availability. We are penning each the information to furniture 1 which is wherefore we person precisely the aforesaid security. But it’s expensive, it represents 95% of the cost.”

Liochon said that Linea’s prover, which fundamentally handles the off-chain computation that verifies, bundles and past creates a cryptographic impervious of the combined transactions, lone represents a 5th of the cost.

This highlights the large hurdle successful making ZK-rollups the go-to scaling solution for the Ethereum ecosystem arsenic opposed to different solutions similar Optimistic rollups.

Liochon besides said that Linea aims to beryllium a wide usage ZK-rollup that volition beryllium utilized for a assortment of decentralized applications and solutions wrong the Ethereum ecosystem. 

"We are a generic rollup. We don't privation to person a circumstantial usage lawsuit oregon circumstantial domain. It's rather important to enactment each benignant of applications, including DeFi, gaming and social."

As Cointelegraph antecedently reported, Consensys has completed the motorboat of Linea successful Aug. 2023, having onboarding implicit 150 partners and bridging much than $26 cardinal successful ETH.
