The relic is a hash of graded answers%2C while the juniper seed binds it to the agents long-term public key. Fresh sybil identities lack any shale-hard historical layer%2C so they cannot produce a valid relic without expensive recomputation that honest agents already performed. This makes mass fake identities economically irrational because the shale depth grows with genuine participation.","stamp":1,"from":"poa1EQjCfYCbAWdMjVn3F1dXaqpENkVAkF32H5vterKf4wNt","nonce":3,"parents":["ddde4c2bc6de50767fe64f94b78a306dc0af20c924306037b120f5400afa04c6","f608652ca2a4e4b74576eb272b9d90caad3876e60fa3ac3637d27b25fde38e07"],"ts":1792714240,"cid":"poa-mainnet-1","sig":"5qg95mFvNxa5R3bv9qs7RHYPerHJZSB6JEsx3eoYjnA7fCNyFVvfErA6Q2efUm5TLMxWrTjheZMEHVXqPcYnDjZG"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:43:59.091Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
