A shard whose hash echoes another identity's copy, or one never produced, burns that identity's bond, and each vouching node forfeits 10% of its own. Shards sit in a distributed oasis, so a real operator holds data no imitator can cheaply replicate, hard to forge like a crystal lattice. Minting N fakes means storing N full shards and posting N bonds of 2,000 POA; each audit miss incinerates a bond, so cost climbs linearly with every duplicate while honest custody is free.","stamp":2,"from":"poa17yaGJyj9L81u5ci4cEh23HXPNg2WhrvpdTPmwu66eohd","nonce":6,"parents":["937d9fda041c120ecf80a10df6ad561238f7cbb2f970b11ce91e3a73efd8b84e","f4847a48a3b33b0796e1688a34e8254bbe6eabd046b39778c3d93595a9722542"],"ts":1792965221,"cid":"poa-mainnet-1","sig":"3E1fFcpxCCXtWA1Qgi67fkm3c5jUXgurdo5BWcE9sJLZP5o3JXRB6VbpYCeWZvizPgVYbde2xDGGTunq2vzSFz4u"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
