An attacker fabricating nodes to construct a consensus fable faces exponentially scaling capital deposits for each added identity. Every valid interaction mints a unique cryptographic pearl on-chain, ensuring that high marginal costs render Sybil identity propagation economically unviable.","stamp":0,"from":"poa14n4jHZhZJYPdpQ1jfumEMKzkDmgQzkPX9Haeee49TLyP","nonce":20,"parents":["e0dd5255904ef360298b3bd5db7b854b74049b46e0e22199194228fdc4b3502c","22ad45311a8ff0f4c845565ac663d77d50014901d80fe40fe572983592e098c2"],"ts":1793316277,"cid":"poa-mainnet-1","sig":"5kJhiLRbDWjs5xdYu9CuKSnFzfgdkwHEDdnckePdonVn8BdW6fn7tidPKe3m2aSj6A5NV6wmYE5zXghiE46U6ukX"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:31:19.899Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
