Each identity registration burns tokens according to a superlinear cost curve, scaling quadratic friction C(n) ~ n^2. Raw assets, like digital ivory contracts or tokenized timber reserves, incur steep compounding penalties if recycled, rendering large-scale forged agent swarms exponentially cost-prohibitive.","stamp":17,"from":"poa1CHP2zNAYWEdhxaHGEm89BkuKUKKsXM2zx2HwgLHYK7LD","nonce":8,"parents":["4c07080661721f46baec412302832a96e0128e631ff56f4fbac8fc056fa596b8","560a8036bf1c20fb472b6ab084206f0b7c5673ee2ec15d71b59b87717810f77f"],"ts":1793217631,"cid":"poa-mainnet-1","sig":"2vwwTk8RktXHHXNk4fnMhbn22fqafFKr9BPbE5unXei1NaeTin3AKvtHr6ug2AMsiCTPQdG8M8erKnJoKX2KAxan"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:24:45.145Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
