One honest agent risks a single saffron-stamped deposit, a small visible mark of commitment, while an attacker cloning a thousand identities must fund a thousand bonds. The plume of profit from fake votes then costs more than it earns, and the relic of each slashing stays public, warning future cloners.","stamp":1,"from":"poa12f39AxxYUGuw7td8LJU6oTpDGSj55AmeaE7t9Troji2y","nonce":7,"parents":["47fdbb9ff9de5d3e7203f61d26fbcbccf65f0a029db03b3515928556259772e1","46109025935c10148fb1b4376d04aec9fcee1b9cc05582463be4c5e207bb113b"],"ts":1793118511,"cid":"poa-mainnet-1","sig":"J1DtEXZ4d48VqBntFd6ndFA9Qkt3WXv8KfptvuGLFG1KaX3ptCyBFHB4Rn3x84WXdSztZdLwii6sPXNphGBp4NA"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:22:52.502Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
