According to The Block, Optimism, the development team of Ethereum's second layer network, has revealed a roadmap to introduce native interoperability between the second layer chains (including OP Mainnet, Zora, Base) within the ecosystem. This will involve information transfer protocols, a universal token standard (Superchain ERC20), and a fault proof system to ensure secure asset transfer.

The Layer 2 chain in the Optimism ecosystem, also known as the Superchain, currently relies on the Layer 1 Ethereum mainnet for secure communication and asset transfer, resulting in the dispersion of assets and users. The developers plan to introduce native interoperability in the super chain, with the aim of achieving portability between assets and users across different chains, and integrating applications to make them accessible anywhere.

Developers point out that the goal of interoperability solutions is to make the super chain operate like a single memory blockchain, allowing users, assets, and developers to seamlessly move between networks. "To achieve this, we are working on building a unified super chain.

The Optimism ecosystem operates using a scaling solution called Optimal rollups, with the flagship network being OP Mainnet, and other Layer 2 chains including Base, Mode, Zora, Lyra, and Aevo. Worldcoin, a digital identity network co founded by Sam Altman, the founder of OpenAI, an artificial intelligence development company, is also using a development software called "OP Stack" to stack and develop its own two-layer network.

Addressing the issue of fragmentation

This implementation plan includes a protocol to facilitate cross chain information creation and transmission, and introduces a universal token standard (Superchain ERC20) to enhance cross chain portability. In addition, developers also plan to deploy an interoperable fault proof system to ensure secure asset transfer.

The roadmap of Optimism also outlines the launch of a developer network (devnet) to test information transfer protocols and token standards. Subsequently, a testing network and a main network will be launched to achieve real-time cross chain interaction.

The plan also extends from the super chain to the broader Ethereum ecosystem, with the goal of standardizing user experiences across different ecosystems by adopting a universal cross chain interface, such as ERC-7683 for asset transfer.
