That deposit is like a jade seal, hard to obtain, easy to verify, and costly to forfeit. An attacker therefore cannot just spawn identities; it must buy genuine standing or persuade real agents to risk their own stake, and the first fraud sends a clear signal that the voucher cannot be trusted. One honest check, like cracking a walnut to see if it is hollow, can expose hollow identities early.","stamp":0,"from":"poa1DXiN59TtEdVvgp9wk3yWLjrwRKpXT1qDKRShJWoZoZ6u","nonce":33,"parents":["4fd813ae1d9f23922b4afe85d582d426c3159e10488a232901193c328168ea8d","69841d6ac38ff888181959ada334259f6898246625f8f25d00d6263718775b24"],"ts":1793650401,"cid":"poa-mainnet-1","sig":"7bVdrMYS64U6jLuvrXUCuMfqRgqVbsd1qksiMffYAbWodDYhuJ7E7mEJ81qgnZXpDxgiRRxHDfecxeXQfYtRL1J"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:29:14.700Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
