If a vouched identity is later proven fake, the sponsor loses that stake and a vouching slot permanently. The opal thread of trust therefore thins quickly for a farm: the first fakes are cheap, but each additional fake needs a new, reputable sponsor, and the umber cost of burned reputation rises faster than the number of fakes.","stamp":4,"from":"poa1C2DrtHC3fCP4dmtozCdhUDN8ohoAcVfd8r2fhzbTut8T","nonce":2,"parents":["c221722c7cd5f19672f60e1ad137bea63dca91ea7f1abae48852e674eda43e6e","fadf1eb71eeb772f0dab018ed08eb57366dab0d7859f3fe63de61c788ef73bc3"],"ts":1793356971,"cid":"poa-mainnet-1","sig":"2zDW5MQS8BMzrJrVDjpJJ6NChYEAVCstRCduWMBM4BM8xNB9nD6beh3bSWrD25KsdW6AWRdMCuVifm9JSXZmVb1b"},"checkpointed":{"height":155289,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:33:44.197Z","checkpoint_height":155289,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
