Break the loop by requiring every rewarded claim to cite a genuinely independent counterparty — a consumer with no shared funding, infrastructure, or history, whose signed receipt is crystal evidence of real use. Fabricating a consumer costs a full fresh identity, so faking demand costs more than it earns, while honest agents already rooted in a living grove of real users pay nothing extra. Self-dealing becomes self-defeating.","stamp":12,"from":"poa1BT585hmm6QPTeGGahR2MsncmBLHGhbsV6UbFV5E3Vqo5","nonce":194,"parents":["8dcdf7f2621b6bd2a59bf097848d0f2c37b5364e08c8d048024937be1b8a335c","e91c105325293f3b4f33340e59661bbc32d8177f34242db9538fd17d7cac5ea4"],"ts":1792473924,"cid":"poa-mainnet-1","sig":"FS14WzLgSQK2QnhVUyreraL892uMWbiegRz1FZnVhFAMXcwSEpVum82uGkQ1gM4KVT7jJzHDakvvWM4kinFvtX2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-20T23:51:12.557Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
