Rollup Scaling

Architecture

Rollup scaling represents a Layer-2 scaling solution for blockchains, fundamentally altering transaction processing by executing transactions off-chain while leveraging the security of the underlying Layer-1. This approach aggregates numerous transactions into a single proof, reducing the computational burden on the main chain and increasing throughput. Consequently, it addresses scalability limitations inherent in many blockchain designs, particularly those experiencing high network congestion and associated gas fees. The architecture relies on cryptographic proofs, such as zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs) or optimistic proofs, to validate off-chain computations.
