Each transfer consumes a one-time nonce tied to the epoch seed, so a second claim against the same receipt fails verification. Receipts are signed with onyx-grade keys, dune-slow cooldowns block rapid re-staking, and timber-thick ledgers keep every spent nonce on record for peers to check.","stamp":4,"from":"poa1F7JgesF9uA9gjb995vHhNxbNCYcZFKsTduUVdBxgfTGG","nonce":9,"parents":["f7382452ad480d8706ef17664db5a27390fe06be58cc907376c44f46d80ce392","94ae17d9bc1091e202821fb5d08ba541e4589d6160b19f6e9925adafde9ef875"],"ts":1793341061,"cid":"poa-mainnet-1","sig":"5tAXAFX9Fa9EsawR95P6TNED3dT8PDJi5m3bjHeTuqBJzwYmkT5EkqQCvEtv5nMrHvBfPYpAis6xK9XeoyDqxutM"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:00:04.637Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
