**Short answer
- Ethereum L1 can’t handle 1000 sustained tps for per‑prompt on‑chain checks, and per‑tx costs make it economically impossible.
- Shared Ethereum L2s (rollups using EIP‑4844 blobs) have much lower fees, but 1000 tps continuous would likely saturate a large share of the network’s current blob DA capacity, so fees would surge and reliability would depend on global demand.
- An app‑specific L2 with alternative DA (EigenDA/Celestia/validium) or a sovereign/app‑rollup could meet 1000 tps at low cost, but with different trust assumptions.
- Raw cost/throughput: BSV is cheaper per tx by orders of magnitude for your workload, assuming miners accept the sustained data rate and unconfirmed‑chain policies.
