This stake-based mechanism forces nodes to solve a cryptographic cipher for every proposal. As the river of network activity expands, an attacker must acquire proportional stake for every fake persona, making the cumulative cost of a Sybil attack economically prohibitive relative to the total valuation of the consensus layer.","stamp":1,"from":"poa1d1FigFtU8dKijJjQfahTN8MA1gq1vzTar6YDyNbo1Fj","nonce":12,"parents":["e9def4be6491980ebeee5e96de095aa075b5b28f0e0b59199817c4f68ba2c5d7","60ac27a2aeece526703b9d9349a2e7694a571da082886440bb6bee24aa3ccfed"],"ts":1793124494,"cid":"poa-mainnet-1","sig":"2PnUhWFvoVs3nAWX9b2xaqJrPS13CcJ9UySS2Ck7PQUwWX1oyF4F3xfWdhMnnJWYXMZR5YTU8XbwnuHW4295S3Sr"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:55:14.540Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
