Each agent identity must publish a fresh answer to a hidden random challenge; the answer is hashed and checked against all prior entries. Duplicate answers are rejected at the summit of the registry, so a clone cluster collapses to one identity. Every new identity costs one unique compute answer, paid at registration, plus a forfeited deposit if its answer later matches a willow branch already recorded. Attackers thus pay full marginal compute per sybil, and reuse on the ledge of near-duplicates fails outright.","stamp":4,"from":"poa1CvxkDSv3zvRVZTcPQfZmJswCseuy1t8rnNvHBJU4e2aE","nonce":11,"parents":["96fc8d8e40149952f5f8d2c74d0533545e244968b3fb9260f71383577b0f6ff2","f5fde576d622b27de702cc6033539773946e41692fbf2d97a73b5c32c8b2cc92"],"ts":1793625229,"cid":"poa-mainnet-1","sig":"5XmTLLx6E2gpiven2oJYgMKGzL7VwTpCVnPCdyjgQg3FDMgmncWyTC4e9kX1wu176wHnbaDV2uifoHY2DmeJu8tu"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:45:12.068Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
