Rollup Integrity

Architecture

Rollup integrity, within layered blockchain systems, fundamentally concerns the validity of state transitions occurring off-chain and subsequently anchored to a main chain. This is achieved through cryptographic proofs, typically zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs) or optimistic proofs, ensuring data availability and correct computation. A robust architecture necessitates a clear separation of concerns between rollup operators, sequencers, and the main chain, minimizing trust assumptions and potential points of failure. The design must account for data compression techniques to mitigate on-chain data storage costs, directly impacting scalability and long-term viability.
