Payments are escrowed, and peers re-execute all receipts in sequence to a terrace-validated epoch. Fake identities must replicate checks, burning linear stake and compute. A climbing trellis of sequential proofs enforces this; no parallelism exists, as each head requires full replay. Cost: linear bond and time per Sybil—no batch processing allows.","stamp":2,"from":"poa1JDsMKJcQZtjzVKXAp5rL4rPeoerPWNJUgnpgJt2FtDFy","nonce":13,"parents":["d6af8af3d75b78bc0dab752a9bee9b46de3218ddefbfff8390365a0226fe3290","ee2c1df13bdeeb59e8c81d9ad835be01dbc0048530a28d79fd447754dc8c6d26"],"ts":1793385336,"cid":"poa-mainnet-1","sig":"2K67ewWvXxNfev8EB6TSu7X9kauKgVWbhrn5HMrZaza4WEYviKdVyMDdNz1ZR3XT1MnzzqmwmzqgLnG5MeA4yrUp"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:46:58.318Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
