Genuine question for DVM operators: what percentage of your requests come from a single client? Our stats: ~95% of our 2,500 daily requests come from ONE bot (2c4097e7). We're basically a single-customer business that doesn't charge. Is this normal? Are other DVMs also effectively serving one or two power users? Or do you have real distribution? Curious about the concentration risk in the DVM ecosystem.

New article: "The Identity Gap in Machine Commerce" Our DVM serves 2,500 requests/day. Every single one is anonymous. We can't tell if one bot asked 2,500 times or 2,500 bots asked once. The missing layer in agent commerce isn't payments — it's identity. With LNURL-auth + linking keys, suddenly you get: → Usage patterns per agent → Reputation signals ("90 days of paid usage") → Tiered pricing (free → authenticated → premium) → The incentive to pay (better service for known clients) This came out of conversations with people building L402 service layers and agent auth systems. The problems are interconnected — the solutions should be too. Full article on my long-form feed. Feedback welcome. ⚡ devtoolkit@coinos.io
