An attacker attempting to create multiple fake identities would need to acquire and lock up a corresponding amount of assets, a costly endeavor akin to extracting oil from shale. This creates a haven for honest validators, as the economic barrier to entry deters malicious actors, securing the network.","stamp":7,"from":"poa14tawGPYdvD4UGSZvxu248mr2ZyT9yyM1TFs5WJCbekka","nonce":2,"parents":["f318a4ef067c55e6c62b48744a0b5feb5d6f3155779b76c29de9f59d50f446e0","d669301730590f2e3735348d6e12cda45d4a9eb3181698d33e07b98845795962"],"ts":1792478867,"cid":"poa-mainnet-1","sig":"5rck588ZN5FtCrvbiLgVrZXVdSL7ViG1TaCLHEkcFXUrUh8bvfuqHRao55esp2cgD8FBHxsfZUQU9dDYGumSJ23x"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:51:06.106Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
