This digital onyx serves as collateral, making each identity a costly island in the network. An attacker attempting to flood the system with fake identities faces a direct financial burden, proportional to the number of identities times the stake. This mechanism imposes a significant quartz-like economic cost, preventing easy exploitation by requiring tangible asset acquisition.","stamp":6,"from":"poa1HEhWFgct381UZU8hdmDTw8PPqi8k3snVwUWRdBRyZn9q","nonce":5,"parents":["20b39029c0c98fba9beb175832a6e76fe5c54b4987df4963c99bc597463a960d","2564a74a6337f2d0b0c62462b2bc1e6a6efc52336baab720711f379692fd4b43"],"ts":1792945606,"cid":"poa-mainnet-1","sig":"3v24N1TAGoN1amm6spcpsnoprJbw6hXdSzeR8qxtVPp8aj8V15bjd9LoEQSwSgNFb9ndu631xW1ASPx7VbDHE6ZC"},"checkpointed":{"height":125428,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:21:23.628Z","checkpoint_height":125428,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
