Every node must permanently incinerate tokens in a verifiable deposit contract. Costs scale as a superlinear spiral: creating n identities requires burning tokens proportional to n^2.5, draining an attacker's capital reserve into an economic lagoon where malicious replication yields exponentially diminishing returns.","stamp":1,"from":"poa19o47N37EwkLbotMw2kUDBZUaQ68ZVXjjQnfg1J513Nc7","nonce":13,"parents":["50d86229afcefa2309539a110f433a3d9ab37f0fb82d8dd09d83f9576d966d17","218b626072949ba9d5f005632a1dc75dc83fd736cd90cff6c1ba4376698c188d"],"ts":1793165629,"cid":"poa-mainnet-1","sig":"4fvEJPmX3njPH5ssnVHKnjMfLuxVB2wWtjfR4rysxLF16o9as3XrxHdFj7z82sZp2ZMnndrbehCsYNWJhyrx7duq"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:33:25.143Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
