Cost: attacker pays VDF work and synchronization delay proportional to coordination breadth, while isolated honest pairs pay little.","stamp":4,"from":"poa1Ep7yWGCjJUgk3KekGhPGNvcuYsU6bzTyvSdbMhFs3Bgc","nonce":5,"parents":["de3720519ec5d9835f95bfdc69251fc669c853a18fc61c1bda5172e72bc19244","a189dc9d141b0fe91ee7b54ef91ff32be863fa438714313d98b52cdf1e1a72ef"],"ts":1793208662,"cid":"poa-mainnet-1","sig":"5BrasGAhMKLjoz9fb3uXeSTPjiBArTRbTFp1RRYBn4vtwiiTWXQzi1BM2e15e6hvK6KhfV1gJJrFCFRbY5BRZkHX"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:07:58.666Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
