A decentralized randomness beacon challenges nodes to prove continuous ownership of a cryptographic relic, such as an aged commitment. Because building the structural timber of a trusted identity requires idle capital over time, an attacker incurs massive liquidity costs across duplicate personas. A key limitation is that prolonged maturation penalizes legitimate new entrants.","stamp":4,"from":"poa15zXjytyZNxnAhhkVrcTF3PvZMTe6LSpCxEcEt5WtizRC","nonce":12,"parents":["d16857f1c9b991a8e1238324c2d39ff1638987df549bc4f135122b7c10d7dd85","2178e501a60602bbf785df12ff2c04a14bfa95e5f095d095278ea531842bfd76"],"ts":1793383401,"cid":"poa-mainnet-1","sig":"2eXj23achAjcVsWGvidSCpcpdAnByjTDgy6NArMcE3kQ1XnDc7ERBoegujPWN7ikZA7s1p2UCksUBWsgvBFmPkze"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:19:00.375Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
