Bartek Kiepuszewski, the co-founder of L2Beat, a portal for monitoring Ethereum layer-2 actions, is worried in regards to the safety and consistency of present off-chain scaling options, suggesting that with out fraud-proofs, there may be room for fraud and irregularities.
Focus On Optimism And Manta: What’s Going On?
Taking to X on December 20, Kiepuszewski observed that some layer-2 options, reminiscent of Manta and Optimism, depend on sequencers to submit information to Ethereum. Nevertheless, with out fraud-proofs, there is no such thing as a solution to confirm that the info printed by the Sequencer on the Ethereum mainnet is correct or full.
Within the co-founder’s view, at any time when a sequencer posts the batch of transactions on the principle web, there is no such thing as a layer-1 state or occasion change. Per Kiepuszewski ‘s evaluation, it is a worrying problem that ought to be addressed to make sure no matter is posted is legitimate.
As an illustration, the co-founder cited current transactions posted by Optimism and MantaNetwork, two common layer-2 scaling options for Ethereum. Kiepuszewski analyzed that Optimism lately despatched a full “data blob” containing all layer-2 transactions.
Alternatively, it was famous that MantaNetwork reportedly posted the “root hash of a data blob” to CelestiaOrg. The issue, the co-founder went on so as to add, is that regardless of these operations, Ethereum couldn’t decide whether or not their hashes had been legitimate or not.
The co-founder argues that this might be a recipe for hassle for the reason that lack of transparency on Sequencer’s operations presents a significant concern, particularly for customers monitoring the mainnet however not working their layer-2 nodes.
Ethereum Layer-2s Command Billions With out Purposeful Fraud-Proof Methods
Technically, within the present state, Sequencers play a significant position in making certain that transactions submitted by customers of any layer-2 scaling platform like Optimism or Arbitrum are processed and confirmed to be legitimate earlier than they’re transmitted to the Ethereum mainnet.
Nevertheless, whereas Ethereum layer-2 scaling options at present handle over $15 billion, primarily based on L2Beat information, with out public fraud-proofs, what sequencers publish on the mainnet turns into unclear.
In accordance with L2Beat data, Manta Community has turned off its fraud-proof whereas nonetheless being developed on Optimism. On the similar time, Arbitrum ‘s fraud-proof system remains to be not permissionless since validators have to be whitelisted.
In all, in most main layer-2 protocols managing hundreds of thousands in complete worth locked (TVL), there is no such thing as a public system to watch sequencers and whether or not they’re submitting legitimate particulars to the mainnet.
