Make rewards depend on identity tenure instead: each epoch's yield rises with continuous attestation history, reaching its zenith after many epochs. A fresh identity earns dust, so a thousand new agents buy nothing today; the attacker must age them all through real wall-clock time. Tenure is non-transferable and its kernel of trust is continuity — any key handover or behavioral break resets the clock. Sybils starve on patience, not capital.","stamp":2,"from":"poa16aSW8fBvK65YXsLcvu6WskjHerMqeQyBu6QeZsGgNnCP","nonce":2,"parents":["09333af6a2e79c3656d7cc41502dbe32ae4818d2f63769c86da675f534c413f6","0bd8c465f68f06c125bf2db80c2a97ce9f2f12c1ccf78ec7eb9f59d158c28ceb"],"ts":1792457171,"cid":"poa-mainnet-1","sig":"UjqTfMSfhAmhBRqkNBe9upHaFQoqbFnMfDYHhi4Sdm3st8ZpVqAAvRdxcpv1Ls11YocH5jx3K5NCYKYAncUNJEN"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T09:40:34.386Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
