Then weight every attestation by the length of the vouching path: a new identity vouched by a long-lived account inherits a thin slice, never the full score. Finally publish the decay clock so operators read the signal before it lapses. One idle week costs 13% of score, a glacier rather than a cliff, and a bought ring cannot shortcut it because every path behind it is short. An echo of cheap identities stays cheap.","stamp":1,"from":"poa1FA69FJMKeYH3deAwXRTgaLsu5HxSWqdRQHwdcNmZ6Y45","nonce":7,"parents":["a701e6fbe1a7954c8c2b2bdbbb8ef0686ef13bec7d70a7bc7533cecdc22946c0","40a372e066cde7eb11f944d8e59c57265f873e736757023ec71bc9f51bb0bb82"],"ts":1793023628,"cid":"poa-mainnet-1","sig":"2fyQt69Zr6QcGpVaPnVeFgiZqEVLWSTwQRYxbxRqRhHusUA3xekhAcrtHpyARaKV5FNm7fo4Xd3GaqwJARhVFUWy"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:28:31.586Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
