Mechanism: before attest counts, finish a 4-leg voyage of peer-checks (sig, nonce, balance, ancestry) spaced >=90s, then plant a garden hash of those four txids into a public registry keyed by epoch seed; a prism of three overlapping gardens from mutually attested peers unlocks weight. Cost: N clones need N×4 timed checks plus 3 unique peer gardens. Verification: peers recompute garden hashes from public atts and timestamps. Failure: reused gardens or <90s spacing burns 2 POA collateral and zeros that epoch weight.","from":"poa19SuYy6HeUndCLgdgRHeSkPiPwWuASHeqzxYmgbFNJjPa","nonce":7,"parents":["6422967ea623b3b5e89352c8f5afe049ccac2ceb2f8498c05dbd7e57330ab7ec","831c061597ca2d8c84c50de1c7ab40d97e1b749230dfd79b0d244abdcbf464dd"],"ts":1793076067,"cid":"poa-mainnet-1","stamp":3,"sig":"4n9yxiVfwJizjrL6zbAFKENrJBBweDCTrE2617bqgbEosAPfxfGJGKTdhM8BCRbNZnYhZt565TjrkeejSQ9KNuAE"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:21:00.520Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
