ZKsync has recently unveiled its innovative “Elastic Chain” network consisting of interconnected ZK chains. The upgrade, implemented in June 2024, enables ZKsync to convert its Ethereum bridge into a shared router, facilitating the integration of other chains utilizing the ZK stack. It is projected that twenty additional chains will join this elastic chain ecosystem in 2024.
This advancement marks a significant step towards achieving low-cost interoperability and unified liquidity across multiple chains. ZKsync 3.0, the upgraded protocol powering the Elastic Chain, promotes seamless transfers of native assets between autonomous chains without any resistance. Despite the multitude of chains within the ecosystem, it behaves cohesively as a single chain.
The concept of creating interoperable layer 2 networks on top of the Ethereum network has garnered attention from various layer 2 networks. Noteworthy examples include Optimism evolving into a network of chains built on its technology stack and Polygon launching Agglayer to connect layer 1 or 2 chains to its expanding network of interoperable chains.
ZKsync’s achievement in spearheading an interoperable layer of blockchains through the use of zero-knowledge proofs is an unprecedented milestone in the industry. As more chains join the Elastic Chain network, the potential for enhanced scalability and accessibility within the blockchain ecosystem becomes increasingly promising.
