Why Most L2’s Are A “Dystopian Nightmare”

Justin Bons, founder and chief investment officer of Cyber Capital, has sparked a polarizing debate in the crypto community with a scathing critique

Cyber Capital founder Justin Bons has sharply criticized several Layer-2 (L2) solutions on Ethereum, sparking a polarizing debate in the crypto community over the level of decentralization offered by these networks.

In a recent analysis, Bons took aim at Arbitrum, Base, Optimism and other L2s, arguing that they pose significant centralization risks. These risks stem from the use of multi-sig controls and centralized sequencers, which could allow network operators to manipulate transaction order for profit or even freeze user funds.

According to Bons, Arbitrum and Base are particularly vulnerable due to their reliance on multi-sig controls and permissioned proposers. This setup could lead to scenarios where user funds are instantly accessible by a centralized authority.

“Arbitrum – Can steal all user funds instantly with a multi-sig, has permissioned proposers, centralized operator can exploit MEV & centralized sequencer can censor,” Bons wrote, adding that “Base can steal all user funds instantly with a multi-sig, permissioned proposer can also steal all user funds, the centralized validator can freeze all funds, a centralized operator can exploit MEV & the centralized sequencer can censor.”

Similarly, Bons highlighted the potential for centralized operators to exploit maximal extractable value (MEV) and censor transactions on Optimism and other networks.

“Optimism – Can steal all user funds instantly with a multi-sig, the centralized operator can exploit MEV & centralized sequencer can censor,” he noted.

Furthermore, Bons criticized networks like Blast for having mechanisms that could freeze user funds under specific conditions, such as insufficient liquidity on the bridge, and raised concerns about censorship by centralized sequencers.

Several industry figures reacted to Bons' statement, with crypto pundit DBCrypto (@DBCrypt0) echoing his sentiments and accusing Ethereum maximalists of being blind if they believe in the decentralization of these platforms despite the “evidence” to the contrary.

questioning the economic incentives for such L2s to adopt a shared sequencer model, given the significant earnings at stake, DBCrypto wrote, “Coinbase currently makes how many millions a month off Base? OP and ARB hold around 50% L2 market share currently? Will they choose to join a shared sequencer and give up much of their earnings?”

Responding to such comments, Bons expressed his concerns about the broader implications of these design choices, emphasizing a lack of consideration for social and economic impacts.

“Some of it can be explained by the naivity of engineers only thinking about technical problems, not social ones,” Bons said, adding that “VCs make much more money off ETH in the short term if it continues with L2 scaling.”

At press time, ETH was trading at $3,049.
