An emerging trend in blockchain scalability is the evolution of Layer-3 networks, Superchains, and hyperchains. These advancements are being adopted by several Layer-2s and are poised to underpin the next generation of Ethereum scaling, streamlining the development process, bolstering security, and fostering greater interoperability across the ecosystem.
Optimism’s OP Stack is pioneering the path towards a highly interoperable network of blockchains known as the Superchain, and the recent Bedrock upgrade represents one of the initial steps towards realizing their vision.
Arbitrum is also at the forefront of Ethereum scaling with its development of Layer-3 networks through Arbitrum Orbit, offering a permissionless framework for deploying customized chains on top of Arbitrum L2.
zkSync has introduced the concept of hyperchains, a network of customizable and trustless linked blockchains, enabling hyperscalability, improved composability, and enhanced security.
