Solana's founder says it has the potential to become an Ethereum Layer 2-compatible platform after a sharding upgrade

Solana co-founder Anatoly Yakovenko said on X that Solana has the potential to become a second-layer (L2) solution for Ethereum through the integration of Wormhole Eigenlayer, strongly hinting at the two The possibility of interoperability between blockchains.

Yakovenko responded to a tweet from Arbitrum co-founder Steven Goldfeder, in which Goldfeder pointed out that Ethereum’s L2 solutions (such as Arbitrum, Aztec and Polygon) are Ethereum. Yakovenko said that through the support of Wormhole eigenlayer, Solana can become an L2 solution for Ethereum. He noted that once the danksharding technology scales, no one can prevent all Solana blocks from being submitted to Ethereum’s data verification bridge contract.

According to Yakovenko, Solana’s integration with Ethereum will be further strengthened after the scalability upgrade of danksharding technology, which will make it possible for Solana blocks to be submitted to Ethereum’s data verification bridge contract. In this regard, Goldfeder believes that if Solana can be settled on Ethereum, it will be an important development. This integration will provide higher transaction processing speeds and scalability, while also bringing more opportunities and development potential to the Ethereum ecosystem.

Additionally, Yakovenko’s comments sparked widespread discussion about the technical details and implications of such integration.

Chainlink community ambassador ChainLinkGod.eth raised a question: If a blockchain reorganization occurs in Ethereum, will the L2 network built on it also be reorganized? He asked whether Solana would follow Ethereum’s reorganization as an L2 network. Answer: A blockchain reorganization is a rare but possible situation that may cause L2 networks built on Ethereum to be affected. However, as an independent blockchain, Solana does not rely on Ethereum for its security and stability. Therefore, even if a blockchain reorganization occurs on Ethereum, Solana, as L2

, further discussed the potential issues around double spending. He noted that if Solana does not reorganize in sync with Ethereum, users may receive additional ETH from the bridge contract. In this case, ChainLinkGod.eth believes this is one of the reasons why Solana is not considered Ethereum L2, even though all block data is submitted to Ethereum and verified by the bridge contract. The existence of this issue may weaken Solana’s viability as a second-layer extension to Ethereum.

Yakovenko clarified that Solana will wait for Ethereum to achieve full finality before minting a wrapped version of the token to eliminate potential double-spend issues.

Solana will not be considered L2 if it does not follow the reorganization of Ethereum and should be determined by social consensus rather than clearly defined in the bridge contract. It is unreasonable to define L2 by subjective standards.

Can Ethereum be used as Solana L2?

Back on July 2, Anatoly Yakovenko even floated the idea that Ethereum could become Solana L2.

He believes that this kind of integration is not as far-fetched as people think. Yakovenko explained that L2 scaling solutions are actually bridge protocols that provide one-way security. Under this definition, he believes that Ethereum as Solana’s layer 2 means that holders of SOL assets will receive finality guarantees. , safely exiting back to Solana even in the event of a transaction double-spend or invalid state transition.

Achieving this setup first requires submitting all Ethereum transactions to Solana and submitting a Simplified Payment Verification (SPV) root as evidence of consensus on the network state.

Additionally, to identify and resolve possible failures within the bridging protocol, a bridging timeout mechanism will be required.

Yakovenko also highlighted the limitations and potential risks associated with such integration.

For example, while it is safe to hold SOL assets on the Ethereum blockchain, it is not safe to lend them out or maintain a position on them.

One major risk is the possibility of an Ethereum failure or a contentious social consensus fork within the Ethereum network.

In this case, Solana assets held on Ethereum could become detached from the consensus fork, causing these assets to become effectively worthless.

All in all, Yakovenko’s stance demonstrates a broader view of what constitutes a second-layer solution, challenging traditional boundaries and proposing a more fluid and connected blockchain ecosystem.
