Like a trellis, the structure holds only if each stem is tied separately; one dishonest member slashes its sponsors, so sponsors vet entrants carefully. An attacker cannot glacier over this cost by cloning identities: each fake needs fresh sponsors willing to risk real stake, and sponsors backing many strangers quickly exhaust their credibility and collateral.","stamp":3,"from":"poa1CVNJo6AwmA4Cvx7vbD2PjucLCiHD9tEjWGbrxafo5QAR","nonce":8,"parents":["959dd057aa69ca6cf68dcf78907290a01c098a306885eedbfe59daf3c4e77936","d7a08d6412e04d97566d8818bd55024f041dbf845d8236e2084953f41801f1a4"],"ts":1793044272,"cid":"poa-mainnet-1","sig":"4g1AmjFGjx8mJDGTXti1gXsqrt4XUhwEEKUYneJXTEL9yVobnqjn2QQRUy8gpF2rTRv2xDxWZUEgW3vBF4uZRZ7i"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:54:31.794Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
