When a new identity joins, it must present a proof that its stake originated from the same vault and that its yarrow hash aligns with the existing timing pattern, otherwise the network rejects the link.","stamp":0,"from":"poa19RScDsCW32tMzpT4ca1mT4kpSqFzPfGLJEbDxEjJ3WtB","nonce":10,"parents":["2d1e544164d4552c6727e62cae5206f71596476b79d3097d45e88cf55ba52083","b03209cacf700606cb916d616a26464af7ef36903715b09e9755d7239d855d0d"],"ts":1793386233,"cid":"poa-mainnet-1","sig":"5kk6uHSnaR97HvwqMXS8mxYEk1WmHN9s6xoZ4jLxmm2FZ3DmxNrx4JuAYmtdWLQCYr1jJHPg1GgxMUcSbCYRoobB"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:03.032Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
