The necessity of seamless cross-chain liquidity access is emphasized in the opening statement.
1. Easy Deployment of New L2
With the help of @0xPolygon’s CDK, @Optimism’s OPStack, @arbitrum’s Orbit, and many other RaaS services, deploying L2 has become easier. However, cross-chain liquidity has become more fragmented. The top 10 mentioned are just the beginning, with countless more.
2. Cross-Chain User Experience Remains a Major Issue
Due to user experience issues, cross-chain interactions have become a headache. The user journey includes extracting liquidity to L1 from the source chain, waiting, adding liquidity to the target chain from L1, waiting, and then starting the transaction on the target chain. Bridge interactions include waiting and paying a premium, as well as facing the risk of trusting a third-party bridge.
3. Introduction to AggLayer and Superchain
AggLayer addresses the issue of fragmented liquidity, leading to inefficient capital and weakened network effects. It acts as a unified layer, enabling low-latency, trustless transactions between blockchains, enhancing interoperability. Superchain, created by @Optimism, is a network of L2 chains based on OPStack, providing scalability for all #OPStack chains.
3.1 Supported L2 Chain Stack (Customizability of Chains)
AggLayer will support any chain that can provide proper input for pessimistic proofs.
3.2 L2 Security
AggLayer is safeguarded by zero-knowledge proofs, allowing all chains that can generate compatible block proofs to integrate into the AggLayer ecosystem. Superchain is strictly built for OP Stack chains, enabling cross-chain data exchange standards for all #OPStack chains.
3.3 Cross-Chain Interoperability
AggLayer’s interoperability is achieved through unified bridging, pessimistic proofs, and proof aggregation. Superchain’s interoperability is achieved through shared sorter method and bridge system.
3.4 Ecosystem
AggLayer currently connects with various chains, while Superchain includes famous chains such as @base, @Optimism, @modenetwork, and @ourZORA.
3.5 Sovereignty and Costs
AggLayer does not require sharing income with connected L2, and the hosting costs are mainly server expenses. Each chain has the right to determine its sovereignty settings. Superchain requires all chains to comply with chain laws, with 15% of the Superchain sorter income used to fund RFP.
4. The Future of L2 Cross-Chain Interoperability
Vitalik mentioned the future of ZK technology in the Ethereum L2 ecosystem, and the aggregation of various Layer 2 platforms reflects the increasing interoperability between different blockchains.
In conclusion, the future may see each institution/company/project/alliance having its own L2, enabling seamless communication between them without the need to worry about directing chain-level resources.
