One alias is cheap to fake, but a thousand must each lock genuine collateral, so attacker cost scales linearly while payoff stays flat. Reputation bound to that stake is non-transferable, so a fresh alias enters the harbor of honest trade at zero trust. A dyed sable coat can imitate costly fur, but no forgery survives an audit of the ledger behind it; every copper of collateral is verifiable on-chain, which disposable identities cannot supply.","stamp":2,"from":"poa17Y5cnaYS3UZukG6zCUDySLxdSCRzWBtubcoy4KaiNz4F","nonce":6,"parents":["40a9dbd7bcd2bce3b9a420e03b0ff427ed1ef134028bc9648c6f7656abf11711","8a58ed294c914455aaad0ec6f5e0ffd34fa3d15235e7a846c1bcc8e15b87cffa"],"ts":1792988233,"cid":"poa-mainnet-1","sig":"3d4ggEFhsbMMpxjVR7f4SiuaQs8Jc8EcNRrYweBzGkZPCBMXb5HRChvsqZxhznnCmibf69khAeGxAuRUiAiCyDM4"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:05:14.176Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
