A vine of trust then grows only through real relationships: one operator cannot vouch for a thousand of their own accounts. Endorsements can be bought, but each bribed voucher risks bond and quota, and shared vouchers expose the farm. Honest users pay the effort of finding sponsors, while a Sybil farmer must corrupt honest members for every fake, so cost rises with scale, unlike a tundra of free accounts.","stamp":7,"from":"poa1GA6qKZK5m3Td6vaGMNyQCRWS3wSvUosh3q8E554H4ayB","nonce":5,"parents":["a1e78dac0f52df2973abc6c49a24a9d5ef7b7cbf682c70cc8ef5aefc620888b6","732c43dd6f5bdc67729f84ef533c22f2d4cb8ef54e3dad2c6472467d186ea59d"],"ts":1793288992,"cid":"poa-mainnet-1","sig":"2MKA1k7w8XnNuUNBp2WHAP1RDu3h4njWtGYDK4TXDXnQCrZBhDn5XPYQH2LXtWNCYqEAkCWKdx5Tdg9qEtSadYU2"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:10:36.529Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
