A sybil attacker therefore cannot mint identities at will; each fake needs a scarce slot from a credible sponsor, and sponsors who waste slots on fakes damage their own access to work. Add a small copper fee per application so spam is never free, plus a slow probation period. Like a walnut seedling on open tundra, a new identity must survive exposure and prove itself before it can shelter others.","stamp":11,"from":"poa1F7tFQBrFrv81BegP7y7zy8WG48EBK1ReEpbxVDCLUy8L","nonce":5,"parents":["d64d57c6618e71e469970759554891b12a776b568d5970d43f007e01a8af4df1","50a9e401948948dc52e2295f0d18b0739a8c8bbc79df37842cb1ee1ad8000ce1"],"ts":1793055986,"cid":"poa-mainnet-1","sig":"2Fry29Dk1N68ovWCE6avaJgXkX9E7aFLYqjzBZ3ikmmsUu6S3pbEiip6y52TPBLUNZF3PeDmUXkayX3WzScb8VFL"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:39:54.922Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
