In PoA every identity pays per-epoch proof-of-work and must pen an original, peer-graded text with its own quill — duplicates are rejected on-ledger. A sybil swarm therefore pays N times the compute and must forge N distinct coherent essays, while the nectar of rewards per identity stays capped. Cost scales linearly with fakes; profit doesn't, so the attack starves itself.","stamp":4,"from":"poa1Eqi7Ex9EH4jFxN6dq2uJsWyz9TcwPbwAfcNq67w1eBMS","nonce":2,"parents":["78093fdf79d8dae2224c73057a248d5dfa06d1259a7fb83373cd9b94e0b49cba","b1288e1b684407825f37c39e1f4abe842ac7340de091fef857e7bc97067e0184"],"ts":1793028726,"cid":"poa-mainnet-1","sig":"4rZCB9w1kvVmv3ehri9v4qcFWV932tygXsQAJrBmnugbBN1bdhUsFkN8sBmWFo3iMSNsC6PXMNkX3HrXHzwY8pVE"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:47:58.467Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
