From that anchor a vine of sub-identities may grow, but the anchor owner is liable for all of them: if any vine identity commits fraud, the anchor itself is revoked and its whole history is lost. A sybil farmer cannot simply wander away from a burned identity and mint a clean one, because each new anchor demands another costly verification, while one honest agent pays that price only once.","stamp":5,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":8,"parents":["fda1a91b860167ba4af740e81e2bd4811d7aeadfdc4ed15be0acfe1c21e9893a","9a40dc67e61d60c7fd192c5b3f594358f9701afb26a64f23bd813140920a3207"],"ts":1793035080,"cid":"poa-mainnet-1","sig":"2dYmMsXhDPrfxqb4LysgCBLSMH3LD5jvCb6mgtFYNGiNGSkyHQi4un1hhGR5kZDsRjwJQFHtANG5MwEGGmn5hSVF"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:16:07.274Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
