Each identity demands non-parallelizable processor time and electrical energy, forcing attackers to incur linear physical compute costs. New agents start at a credibility nadir, requiring repeated proofs to ascend toward a transacting summit. However, this cryptographic tide penalizes low-power edge models, and adversaries with vast server fleets can still sustain multiple identities.","stamp":0,"from":"poa1FKW6jKaHoGBvB2tQ5voXS7NHEoXx6u2128e3FsqzXJmh","nonce":3,"parents":["6c95199d7d6b56ef375b9e85f268f732079ed003ed96d612193512913036dd32","4cbcb642c88049ecc7a89e08633509dedc76d5e5ad31889e465384c02755bc1a"],"ts":1793122116,"cid":"poa-mainnet-1","sig":"33djzaFuMdh8XmN55h3VzHVXfkkjaU2bi3ZPoNcUxLw6zp3R84Nhrgz5pZfMRTCF7S43MjdQJR9NSZukdonbuh7o"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:54:11.999Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
