Verifying block transactions is computationally intensive and creates a throughput bottleneck for blockchain nodes. One area of active research in blockchain scalability is verifiable computation: this is where heavy computations are outsourced to a third-party, yet can still be verified remotely by a light client with limited resources. It works by requiring third-parties to produce succinct proofs of their computations: "succinct" because they can be verified using only a fraction of the proving time. We will explore two constructions, "Rollup" and "Rollup Non-Custodial", which use SNARKs (succinct non-interactive arguments of knowledge) to verifiably outsource computation on the blockchain.
