Ethereum co-founder Vitalik Buterin came up with plans to improve cross-chain L2 communication, which will improve the user experience within the Ethereum ecosystem.
In the Aug 6 post, Buterin responded to a question to resolve the cross-layer 2 issue. He explained that people will think about how fast the problem vanished from cross-layer 2 and how smoothly the Ethereum ecosystem is working
He further added that he sees “lots of energy and will to make this happen,” before mentioning some Ethereum Improvement Proposals (EIPs) in the process of l2 communication.
One next step in the roadmap is EIP-3370, which introduces a new address standard for wallets and dApps. This standard uses a human-readable prefix to show chain-specific addresses.
The second step in upgradations is EIP-7683 which establishes a standard method for other Ethereum layer-2 networks to communicate and perform trades across chains.
In recent times, it has been difficult and ineffective for users to make trades between different networks. To overcome the issue, it is important to introduce a new set of rules that will be followed by all networks.
Another part of the roadmap is EIP-3668, which is a proposal for a standardized way for Ethereum smart contracts to access off-chain data.
Ethereum co-founders call it “layer-2 light clients” as it has the potential to standardize how Ethereum contracts can access off-chain data. This process makes it easy and effective for developers to develop applications that need large amounts of data without paying on-chain storage costs.
Buterin also explains “cross-L2-replayable account state updates,” which refers to how L1 will get an update without affecting the privacy of the system and low latency in the transactions.
He also mentioned a few phase 2 updates that will further enhance the cross-chain L2 compatibility which involves keystore rollups, and proof aggregation.
Regarding compatibility with current zero-knowledge and optimistic rollups, he said these “stage 1” updates are “completely independent of roll-up technology details,” and then concluded:
“Eventually, I think all rollups will go zk (and existing zk rollups will have to redo their tech stack), in order to finalize to Ethereum once per slot. But that’s like 5+ years away.”
At the start of 2024, investment manager VanEck predicted that the L2 scaling could hit a $1 trillion market cap in the next six years.
