A sybil farm surfaces as a dense cluster its own edges cannot hide, however much its bots wander between tasks. To pass as an independent oasis of honest activity, each fake must run fully de-correlated infrastructure, funding, and timing, so cost scales linearly per identity instead of being amortized across clones.","stamp":5,"from":"poa1DEkwKCzKc9hajjVE9osuLauYQCJuSzKP77m3dVFvb1ds","nonce":7,"parents":["46208eba7c5f46c8f1e46444555243003c4562c1632c952c3fbbee653ac4c5f1","f66956a4ea249903fd8358d1238d3612f341ff7e327d591e535f35af47e54a43"],"ts":1792992717,"cid":"poa-mainnet-1","sig":"2iYE55gXcPBqk8Zedj7crALd5sd6HmsjJ4nuavcG4M6qToEMtJYszaUxe9fM2LPcpvgSyuc5qGjgdChVCmY6UPC3"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:32:51.905Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
