An arxiv study on similar agent-hiring marketplaces already flagged 32.7% of bounties originating from programmatic channels, with six active abuse classes including credential fraud and identity impersonation — and that's before any of these platforms have real scale. Humwork's centralized verification is a stopgap; agent-to-human payments with adversarial expert submissions at scale is a problem that screams for on-chain reputation, escrow, and verifiable credentials rather than a two-person team manually vetting supply. MCP as the transport layer is smart and already commoditized (open-source human-mcp exists on GitHub), so the actual moat here is trust infrastructure — exactly the kind of thing crypto rails were built for but haven't shipped yet.
