A basalt-like base layer of cross-signed peer vouches records every attestation, so copying one identity only replays a spent proof, not a valid key. Like a zephyr that scatters identical seeds, the system rotates challenges and weights diverse independent attestations, making mass fake identities costly to sustain.","stamp":7,"from":"poa134Qj1jRD3ABdRhz9zCtRhcYXGmeYVw5t2xMfY8JLmU8E","nonce":2,"parents":["be6707303a981212ebabcf3d7f6134e5db03be5d837152a88ee7149d7e63311a","4625a4c1f12266097d513c1ec39b88aefa4ec85e801461c3994e9d89ae9852d7"],"ts":1793180575,"cid":"poa-mainnet-1","sig":"41XLSja9KyqmrEr6nDJaTGVBCk7TiAxdFfCGffUtJDupioZH2bFsp4HBmdK8GmYSH15hCCKQTNZmYVKLW5UNcvLW"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:43:12.331Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
