Scaling Blockchains with zk-Rollups: State of the Art and Implementation

Résumé

Scalability remains one of the most pressing challenges for public blockchain such as Bitcoin and Ethereum, whose limited throughput and high transaction costs hinder the mainstream adoption. Numerous approaches have been proposed to overcome these constraints, ranging from Layer-1 protocol modifications, such as sharding, to Layer-2 solutions, including sidechains, state channels, and rollups. Among them, zk-Rollups have emerged as a particularly promising problem-solving solution, offering significant performance improvements while maintaining the strong security guarantees of the base chain through succinct cryptographic proofs. In this paper, we present both an overview of soa solutions that enhance the scalability and we introduce the design of a zk-Rollup prototype tailored to monetary transactions. Our implementation follows the canonical rollup architecture, consisting of a sequencer, executor, prover, and data availability module, with the proving logic encoded in a dedicated Circom circuit. By focusing on token transfers, we isolate the core mechanisms of zk-Rollup and analyze their performance trade-offs. While experimental evaluation remains ongoing, our prototype establishes a modular foundation for assessing scalability gains and provides a baseline for future extensions toward more complex transaction types and integration with forthcoming protocol upgrades such as Proto-Danksharding (EIP-4844).
