Recently, the once somewhat well-known Layer 1 public chain Gnosis Chain decided, through a resolution, to transition from its current Layer 1 public chain to a Layer 2 scaling system (L2) dependent on Ethereum.

The Gnosis project will not be unfamiliar to some early participants in the crypto ecosystem. Its most famous project is not this current L1 public chain, but rather the multi-signature wallet on Ethereum.

I was once one of the users of that wallet. It was frequently used during development experiments with some friends, but later, as my interests shifted, I stopped managing that multi-signature wallet.

This may have been because relying solely on the wallet made it difficult to expand the business, or it may have been influenced by the atmosphere of building public chains at the time, leading it to vigorously construct its own L1, now known as Gnosis Chain.

However, after it built that chain, I never used it, nor have I seen any of my friends who once used its multi-signature wallet use it, so gradually we all forgot about this project.

It wasn't until I recently saw news about its shift that it rekindled my past memories.

The transition from L1 to Ethereum's L2 is neither new nor surprising. I had shared my views in earlier articles—most L1s in the future will either die or become L2s dependent on Ethereum. Many of our readers have also expressed similar opinions in their comments.

But this time Gnosis's transition has something special about it—the technology and method it chose are quite sophisticated and the team has put considerable thought into it.

It did not adopt the common OP technology, nor did it use the common ZK technology, but instead chose a new technological framework jointly proposed with Zisk: EEZ, which stands for “Ethereum Economic Zone.”

A core highlight of EEZ technology is to achieve synchronization between Ethereum L2 and the mainnet.

This synchronization mainly solves three problems:

- Security of L2 cross-chain;

- The Ethereum mainnet cannot capture and share the value acquired by L2.

- L2 isolation and liquidity fragmentation.

To achieve communication between the mainnet and L2 as well as between L2s, one must either use an official cross-chain bridge or a third-party cross-chain bridge.

If using the official cross-chain bridge, one either waits for a 7-day challenge period or, even with the most advanced zero-knowledge proofs, has to wait several minutes to several hours.

With a third-party cross-chain bridge, it leverages the liquidity of the third party for faster confirmation times, but this requires the third party to have sufficient liquidity as a guarantee. Moreover, this poses significant security challenges for third-party cross-chain bridges, often making them targets for hackers.

In contrast, EEZ does not use cross-chain bridges and directly uses zero-knowledge proofs to enable all L2s to confirm each other's transactions in the same block of the Ethereum mainnet. This is akin to executing different contracts on the same chain, allowing it to break free from reliance on third parties while eliminating long wait times.

It resolves the cross-chain security of L2.

The inability of the Ethereum mainnet to capture and share the value acquired by L2 is already a well-known and significant issue, and it is one of the reasons many people criticize Ethereum for struggling to gain value support.

EEZ’s solution is to return the ordering rights of transactions in L2 directly to the validators of the Ethereum mainnet, forcibly reclaiming the value capture rights and mandating that all L2s must use Ethereum as the settlement currency.

The issue of “L2 islands and liquidity fragmentation” is even more apparent. We only need to look at how Uniswap has deployed its own DEXs across various L2s to see how serious this liquidity fragmentation is.

EEZ’s solution is to utilize Zisk’s millisecond/second-level real-time zero-knowledge proof to verify the cryptographic states of both source and target chains within the block time of the same Ethereum mainnet block (12 seconds), thus achieving cross-chain synchronous invocation.

From the user’s perspective, the DEX on Arbitrum can directly match liquidity orders from Robinhood or other EEZ member chains, with transactions either succeeding completely or failing entirely, thereby achieving “atomicity” with no intermediate ambiguous states.

This way, DeFi protocols do not need to establish independent liquidity pools on each L2; rather, they can deploy liquidity pools in any L2 or the mainnet within EEZ, allowing other L2s to be informed and utilize this liquidity.

This addresses the problem of liquidity fragmentation.

While the EEZ solution appears very promising, it faces a significant obstacle in execution: L2s must automatically relinquish their tightly held transaction ordering rights—this is their gateway to fiscal revenue.

Now Gnosis Chain has set the first example.

However, the ecology of this chain is too weak, making it difficult to predict its impact. To genuinely drive trends or create a wave, big players like Base, Arbitrum, or Robinhood Chain must set the example.

But who would easily give up their already acquired benefits for the sake of the entire ecosystem?

We can only wait and witness over time.
