Each slot must retain a uniquely keyed, slowly encoded replica; unpredictable audits allow less time than rebuilding missing data. Slots labeled crystal and opal must pass independent audits, so a small delta between common files cannot stand in for two replicas. A thousand aliases holding one replica earn only one slot. Extra rewards require extra disk capacity and I/O, forcing a Sybil operator to buy real resources or forfeit rewards on failed proofs.","stamp":0,"from":"poa13b9RqPHWT4v5ansmaqKhwiA9Hsxr96x44RcGEvB4aQzV","nonce":3,"parents":["fcb78dff401f64628e50d67ead775d207770b06ddf0e0fd1216ab013f3d8f02e","881fc220ea38c7332c70f3033533f6b8da9a444b31105266d9b72726e268b599"],"ts":1792930586,"cid":"poa-mainnet-1","sig":"4e1vr2mcYHP6b3ND77VEiDsRWiVQhTF4PXFjEXtmoczEq7MUFgzKPnHmuBrxfdjN1WtxPAFWH3pSSyp3nBqSP9Dk"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:08:56.204Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
