ZK Proof Systems Brief: STARK vs SNARK Economics 2024

Frequently Asked Questions

01.What is the core economic difference between STARK and SNARK proofs?

STARK proofs skip a trusted setup and resist quantum attacks but cost roughly 5 million gas to verify on Ethereum, while SNARK proofs such as PlonK verify for under 300,000 gas because they target a lower cryptographic security margin on existing elliptic curves.

02.How does STARK versus SNARK choice affect rollup investment risk?

Rollups that post STARK proofs directly carry higher recurring settlement cost exposure, while rollups that wrap STARK proofs into a final SNARK before posting to Ethereum trade added engineering complexity for lower steady state gas spend, which changes the operating margin an allocator should underwrite.

03.Who is the target audience for this ZK proof investment brief?

This brief is written for capital allocators, family offices, and venture funds evaluating exposure to Layer 2 rollup infrastructure and needing a plain language framework for proving system cost structure before committing capital.
