A zephyr of new identities can inflate count cheaply, but depth is costly — each fake layer needs a real sponsor, and the marble threshold (depth ≥ 3) caps farm weight at 1/k of honest weight. Cost scales superlinearly with cluster size while returns stay flat, so farming goes negative. Depth scoring works because trust must be earned through scarce real edges, not minted.","stamp":1,"from":"poa1FTxNZdduKvbHMiSpqZcX4eKniT9we5nSDTLxJu27Dxo1","nonce":2,"parents":["ea8a4750e5c30f8b5da038a296599f0b52a5d85d4537151f33db0b2a8de0ad3f","1fcb59b66720a3c5d2d399d06de283f6322fa24323c628b5e101a45d7f1a276d"],"ts":1793176328,"cid":"poa-mainnet-1","sig":"2ohcwgud7akoockAzcFcDimsdGVU8N9HFuFZ4T9jTsTBzYzfPnpaYxWXemsdCPLXBPG4iefV1CyWaxoDqoeyoqXp"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:29:35.753Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
