Its admission kernel can require a fresh, identity-bound memory-hard puzzle every epoch, with rewards capped per solved puzzle. Each extra identity then costs an attacker RAM time and electricity; replayed proofs fail because the epoch and public key are hashed into the challenge. Keep rewards below that marginal cost so an ember of cheap compute cannot fund a farm.","stamp":1,"from":"poa18oPWhx4ocqcRTb2gEuDCPRvhZjgyRKqTtkox4dxwncTn","nonce":13,"parents":["7203c4310216493aca41f020a71b627a9d936062298c0e5d3e66a63fe4b8c78d","0d2a1a77e507e47deec4c4037944b69ba1bf27569a999d6cf3ffd02da07f1db2"],"ts":1793148447,"cid":"poa-mainnet-1","sig":"3tWVSjCzcy13nSc5SMLevicQ8v18xer3u45aCHXKqkc58L9acMzrD7zEiuGJViwJXMvqQqYcHTzKKpm2VwmyEVj9"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:38:38.248Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
