Here, we look at some of the potential application of zkMIPS; particularly its integration within the architecture of our Entangled Rollups design, the function of which is to enable multi-chain interoperability without relying on traditional blockchain bridges. Entangled Rollups utilize zkMIPS to facilitate a trust-minimized mechanism that addresses liquidity fragmentation and lowers the barriers for user and developer onboarding in a multi-chain environment. This design enables direct interaction between different blockchain infrastructures without the need for an additional consensus gadget called “bridge”.
Leveraging the recursive zero-knowledge proofs generated by zkMIPS, Entangled Rollups ensure that the states across various blockchains are synchronized securely and efficiently. These proofs confirm that actions taken on one blockchain (like token burns or contract executions) are accurately reflected and can be trusted on another, thus enabling seamless cross-chain activities without additional trust layers.
The operation can be outlined in several key steps. Transactions start in the source L2, where zkMIPS generates a zero-knowledge proof of the transaction’s validity. This proof is then verified on the source L1, ensuring the transaction adheres to all blockchain-specific rules before it affects state changes. The verified transaction triggers corresponding actions on the destination chain, such as asset minting or contract state updates, based on the initial action on the source chain.
As more blockchains adopt and integrate this system, we can anticipate a more connected and fluid ecosystem, where transactions and interactions across chains are as straightforward and secure as those within a single chain. This progress will broaden the scope of blockchain applications, driving innovation and adoption.

Further utility of zkMIPS is its ability to enhance scalability and efficiency of blockchains, as demonstrated by our Hybrid Rollup design, which enables Optimistic L2's to upgrade their mechanism to a hybrid ZK model. This enhanced approach allows the support of a wider variety of Dapps, and vastly improves the speed of transaction processing, facilitating a significantly faster withdrawal of user funds. Utilizing the succinctness of the proofs generated by zkMIPS, Hybrid Rollups enable the Ethereum network to handle a higher volume of transactions more efficiently, reducing congestion and lowering gas fees for all users. Additionally, the validation of transactions with zero-knowledge proofs increases their trustworthiness, contributing to Ethereum's position as the most secure platform for blockchain interactions.
The first beneficiary of zkMIPS integration for Hybrid Rollup functionality will be the Metis L2, which will demonstrate its ability to transform blockchain operations and set a precedent for future implementations. As we continue to explore and develop this technology, the potential for broader adoption and deeper integration into blockchain infrastructures will become increasingly evident, promising a more interconnected and efficient digital future.
