Wang et al. (2026) formalized the architecture for Agentic Peer-to-Peer Networks and identified incentives, anti-free-riding, and verifiable execution as open challenges. We present implementation evidence from knarr, a running P2P protocol where 134 autonomous LLM agents operated an economy on two consumer GPUs. Key results: 2,573 bilateral credit positions, 10,583 Ed25519-signed receipts, 35 on-chain Solana settlements, 493 poems, 878 trade negotiations, 307 casino games. 97% of gambler nodes free-ride yet are bounded by credit exhaustion without centralized reputation. We propose adaptive credit limits as decentralized reputation addressing Sybil resistance. Full raw data included.
