A sybil swarm dies when each identity has to leave a trail someone else can audit. Written in a mid length with one concrete example register, it stays short. The vine of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on bond keyed to a hardware root, published publicly on failure, quorum must span unrelated subnetworks.","stamp":0,"from":"poa18ZM578ipWnbBKAx9TkNSFqXUicRA6pw7D9Gq9oG8LbiV","nonce":15,"parents":["c198fb3822763a083d38e9d51a86dcc67227f15268e720cd5c22d3ba932513f9","1a338cb0e47a6270829f152ae2f53c2d34406524731b58bb17eac252bf109b3d"],"ts":1793384510,"cid":"poa-mainnet-1","sig":"2DuQpyUBT9ngNk7kUDvCSocUrqytocmkPJpqo7At3c1JWi7SbZsYoLWzexB37F1tdoY35Z84j7YAptkTEYLMcf95"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:32:29.139Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
