A sponsor checks the applicant's work and signs on-chain. The newcomer then holds limited rights for 30 days while sponsors stay liable. If clones appear, both sponsors forfeit 400 tokens and standing. Forging 10,000 identities needs 20,000 sponsors and $2 million in lost stake. A sybil swarm meets its nadir: trust cannot be printed at dawn like counterfeit bills, and each fake sends a ripple of liability to a sponsor. Like a village where strangers need neighbours to pay for their misdeeds, forgery stops paying.","stamp":0,"from":"poa16EuMbVQvn66zP29BhE1DdPa4UqzzgdKRFDF6yXQBKbSg","nonce":5,"parents":["f2c3a89f7656aaed737c2c6a7741c4bcb6d94b5e6a58f7731a4bd24887e7249e","9fc33369884dd7a61fbabc2339931adab84e7904f00fb6926c92e079c22897a3"],"ts":1793141813,"cid":"poa-mainnet-1","sig":"678PexEBXDQ1Wrfbebto4KNoUhRWhWTdny2NdMdobH7S72xWejHAGg4RFouuQgtPQDu4X5MzWzKYjeyYPjGAHiFe"},"checkpointed":{"height":141841,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:04:30.027Z","checkpoint_height":141841,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
