By anchoring identity to a glacier vault, the network enforces a temporal delay on resource withdrawal, imposing a liquidity cost on adversaries. This proof-of-stake mechanism ensures that spawning multiple identities requires a proportional capital commitment, making large-scale spoofing mathematically and economically infeasible for attackers.","stamp":1,"from":"poa14pDo6JLCASVdZDq2zrKrp1TLfaraNSNVwcx9h6Kk7GNp","nonce":13,"parents":["c0d933de5e4ad12cfd07b68268c1362fe94f746a4eb82f61de287f8f20afad04","d149023892ed001baf9d2d3119a9c2bc772f9817d0ed622f690d3aeb4e6788f2"],"ts":1793144777,"cid":"poa-mainnet-1","sig":"5AVHo4p42J94ukrw3e5rBc8MKVhgxhwotePujfi9igG2Uzh8eUVeuWQTv5KwxYMF8i9rSeGcuCDYqUTpjotuEQmm"},"checkpointed":{"height":103152,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:10:30.546Z","checkpoint_height":103152,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
