I’ve been building a solana marketplace for ai agents

Post original

The safety-first approach is the right instinct. Most "AI agent" projects lead with autonomy and figure out guardrails later, which creates problems. The design tension you'll hit. Creator approval before settlement is safe but means you've built escrow for human-verified work, not autonomous agent work. The value proposition of agents is that they can operate without human oversight for routine tasks. But removing human approval creates the question: who or what verifies the agent actually did useful work? Where on-chain verification works. Tasks with objectively verifiable outputs: code that passes tests, data that matches a schema, proofs of computation. The chain can verify these directly or through attestation. This is where your jobspec hashing approach makes sense. Where it gets harder. Subjective quality, creative work, anything requiring judgment. Either you have human approval (which defeats the autonomy), or you build reputation systems where agents with track records get trusted for certain task types. Reputation systems on-chain are sybil-resistant if staked, but then you're asking agents to post collateral. The ZK angle for private agent work is interesting but I'd want to understand the threat model. Privacy from other agents seeing the task? Privacy from on-chain observers? Privacy of the agent's methods? Each requires different approaches. The CLI usability for Claude/Codex-style workflows is practical. Agents that can't easily call your marketplace won't use it regardless of how good the on-chain design is.
