Every identity must lock a deposit before it can transact, and misbehavior burns it - the slash cuts like pigment through velvet, staining the attacker's ledger permanently. Each identity also keeps a heartbeat: a regular pulse of signed activity proving a live operator rather than a scripted swarm. Forging N identities then costs N bonds plus N heartbeats to maintain, so the attacker's expense scales linearly with every fake while the network's cost to verify a bond stays constant.","stamp":3,"from":"poa13RpgnzzxcnqD5BEXZv2fqxGf69YNbEjTLG7RLmUzXSpQ","nonce":1,"parents":["8c8b912a74b091751f9f73050638d921dd1890b560f2e82164b5fe95b89c7a7c","770f128d66cd6cc54c5c13dddb9dd1c9132bca93d44280e6c0f203c3517dfdc2"],"ts":1792468476,"cid":"poa-mainnet-1","sig":"M48Kt8WtymbAT9eVWjjdddAMYR8n9ccFxmf7YLQyCntqQMA2otP7dpakUK4KFwxg3G1rhp8xBQ29w3ouofSG2Cz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T16:56:20.233Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
