We present a novel stateless zero-knowledge rollup (ZK-rollup) protocol with client-side validation called Intmax2. Our architecture distinctly diverges from existing ZK-rollup approaches since essentially all of the data availability and computational costs are shifted to the client-side as opposed to imposing heavy computational requirements on the rollup aggregators. Moreover, the data storage and computation in our approach is parallelizable for each user. Therefore, there are no specific nodes to validate the contents of transactions. In effect, only block producers, who periodically submit a Merkle tree root containing all the transactions, are necessary.
