Galaxy’s Alex Thorn calls Ethereum L2s ‘ETH extractive’ amid fee retention concerns

Galaxy head of analysis Alex Thorn criticized the enterprise mannequin of many Ethereum (ETH) layer-2 (L2) blockchains as “ETH extractive.”

In an Aug. 6 social media submit, Thorn argued that L2 networks retain many of the payment income whereas contributing comparatively little again to the Ethereum L1. 

Thorn added that the majority L2s are managed by single firms or foundations, which implies “little or no worth accrues to ETH holders,” and “most L2s don’t even stake again the ETH they gather in charges.” 

Publish EIP-4844

Pointing to post-EIP-4844 dynamics, Thorn famous that mixture L2 blob affirmation prices and L1 gasoline spend have hovered round $10,000 per day, whereas L2s earn from $100,000 to $400,000 each day in person charges.

Because of this, L2 earnings depart “a pleasant margin even together with operating the chain.” Blobs are devoted areas providing information storage utilized by layer-2 blockchains constructed on prime of Ethereum.

He additionally contrasted funds from Base to the Optimism Collective, since Base makes use of the OP Stack, versus funds from L2s to Ethereum. During the last 180 days, Base paid $4.4 million to OP, whereas all L2s mixed paid $3.05 million to Ethereum L1 for blobs and gasoline.

Thorn additional claimed Coinbase made $14.9 million in Base payment income in Q2, with $443,000 in L1 information prices and $2.16 million paid to OP, saying “OP is actually making 4.8x extra off Base than Ethereum is.” 

The critique culminated in a broader alignment query, to which Thorn responded:

“…They aren’t actually ‘eth aligned…’ they give the impression of being fairly ‘Eth extractive’ to me.”

Lengthy-running debate

Base graduated to Stage 1 in April on information aggregator L2Beat, an intermediate decentralization tier envisioned by Ethereum co-founder Vitalik Buterin. 

Stage 1 signifies improved fault-proofs and governance safeguards, whereas Stage 2 is outlined by an L2 having no group of actors that may submit a state root aside from the output of the code, even unanimously.

The L2 powered by Coinbase was amongst different chains that not too long ago up to date their safety measures to forestall methods to dam messages to the mainnet aside from compromising not less than 75% of the community’s safety council. 

Thorn’s argument revives a long-running debate over how a lot financial worth L2s ought to return to Ethereum versus to their operators or upstream collectives. 

The post-4844 value construction lowered L2 information prices by introducing blobs, however the stability between person charges retained by L2s and L1 spend and staking stays contested.
