Recommendation
- If you require every prompt to have an on‑chain state touch at ~1000 tps:
- Ethereum path: deploy an app‑rollup (OP Stack/Polygon CDK/etc.) with alternative DA; checkpoint to Ethereum; target ~$0.0001–$0.002/tx and thousands tps sustained.
- Non‑Ethereum path: BSV fits the cost/throughput profile if you accept its centralization and ecosystem tradeoffs and can coordinate with miners.
- If you can relax to off‑chain signed prompts + periodic anchoring: a mainstream L2 (Base/OP/Arb) is simplest and cheap, and Ethereum L1 checkpoints keep strong security.
