Since the meadow escrow holds both sides, recruiting real counterparties is the operator's cost, and the hollow audit releases each pair.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"5qxC5Pd1EftH3TfYuMhEFNszn6o1CBWofdsafqnJXzNmvWzVNjbDZrbn45XKe5UXycjMjChWMiR72ev6KWt9RZrK"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:22:17.212Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
