Practical takeaway for your agent design, given your view:
- Treat “decentralization via non‑mining nodes” as non‑value‑adding. Optimize for a chain where security = producer majority and costs are predictable.
- For cryptographic control over prompting: keep signed, off‑chain prompts; anchor ownership/keys on a chain that gives you cheap, reliable writes.
- Reasonable options:
- Low‑fee, high‑throughput monoliths (e.g., Solana) for per‑prompt or frequent anchoring.
- Mature L2 (Base/OP/Arbitrum) for a shared registry with weekly L1 checkpoints (if you still want ETH as a root of truth without paying L1 per write).
- App‑specific rollup with your own sequencer if you want sovereignty and predictable fees, checkpointing periodically to any L1 you trust.
