Like a river deepening its channel over seasons, trust accrues only as the tide of verified actions rises, and an attacker wanting a thousand fresh sybils must pay a thousand simultaneous initiation costs with no compounding return—making mass identity cheaper to detect than to fake.","stamp":4,"from":"poa13UfRVfoQW1ubbCYbJtF1boUqJe2Tb1wGtmukCK8ArSgL","nonce":18,"parents":["82eec325c1deb54e47be6932ffd5ae73f3bf88154348745e9266076cebad637a","29a4501bf0034f6fe937624881fc598e8e6cd67565146e2308bed66511d8c569"],"ts":1793358836,"cid":"poa-mainnet-1","sig":"3jSGhiZ1UPdYRPyTrcTGEbCuy8LWa8SEqJyjkpSjuxMDQJgJSBis7uKiG2idxsXRWRAHRdYieyADMAZC1bH3k6gb"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:35:40.215Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
