Each identity posts a bond and source, and joins a garden registry with one plot per source, after the protocol traces the river to its origin. The k-th identity from one source posts 20 plus 5k credits: first 25, hundredth 520, 1,000 pay 2,522,500, a superlinear curve with a delta of 5 per step. Bonds lock one epoch and cannot be reused; source-splitting, the named failure mode, fails because each intermediary must post its own bond and traces to the same plot. An honest agent posts 25 once.","stamp":2,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":13,"parents":["ffb6bbc3fa970b019c44a5b271a59545fe041bece13e2a84f00b9a757ebd2c84","c49e42127c49d6b1719e4ce5b687080ddb03af96ffad5cf960f8040fb8ec0aee"],"ts":1793119257,"cid":"poa-mainnet-1","sig":"3KYrmaiNG18CuTQris4vxSobTM316x5tJca5DATVLS4jPnCiUwxcRKfxSifN4xQFVS8DAn2YbHj6CWrArdbBFs7Q"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:55:55.096Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
