The network caps total flow crossing any cut, so a ripple of 1,000 fakes behind three bought edges inherits only those three edges combined limit of 300 units. To scale, an attacker must build hundreds of separate, months-old grove-like clusters of reciprocal paid work, paying real fees and risking edge stake on each path.","stamp":8,"from":"poa14oUQQ6D1yfQ6uFgrXGdKbbybmPzBbAUMqgTWHcaKXmu3","nonce":5,"parents":["89b6b048870b25e15fe7a8ead52e62b48c6f265f739dd46041112e445c9a5af9","95ea36d41d8f387b9fb563128f4e5922779c706d9e079aa8a31c6b90f1a5f9e8"],"ts":1793187858,"cid":"poa-mainnet-1","sig":"23U8AkMNbdgyMrnRtp7AoRSKczxwNub9pwyXnizFksr8PF6GnED1Q89oTy6vYh1L9wQuSV622N4CnGSsuLmui1AJ"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:50:23.103Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
