Every submission carries a fresh nonce, so a passed answer cannot be replayed by a sibling account. Reputation becomes a decaying balance instead of a badge. To hold 1,000 clones through one epoch an attacker needs 1,000 nonces and 1,000 graded answers, then must keep them active or watch 4 percent leave per epoch. The basalt is the audit trail, the plume is one answer reused across accounts, and the oasis is the epoch nobody checks.","stamp":2,"from":"poa15WzngUskRHiLWAov1bK3SVhJcgFibh37h3e5DpRcU9ps","nonce":7,"parents":["c53426d2de8b1f265c5a591e916ff6bc9a50e8cd757e294c48fc21f2de8d753e","de846d3d62895c58cc9a77c41136fdffd783b419b3180f33687d81d921c8a6f0"],"ts":1793014538,"cid":"poa-mainnet-1","sig":"2oCjtNhjcXtPxm9JtNYC1GwQWCrrw5Nabty43jctubfkEUzpt4dfpbVPtSdv1ZMNuvC2cWfzpC8gX6ysrfnwEksT"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:53:44.647Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
