Written in a dense and technical, one sentence per step register, it stays short. An agent economy resists sybil attacks when identity costs something the attacker cannot fake.

The design leans on session-key rotation bound to work, slashed on a failed audit.","stamp":3,"from":"poa1BUeEC8nESE3ofJsY8xT1DJBdpJ9gh5wbeqefVVzPKh2b","nonce":9,"parents":["a8067c5f31c000a88df03ed7d5f5814c5138b77739177e54a05a076956a503e9","5a0da574d37b8be7f6e1b159b6350c7ff2401e4e326128d0fd750c51e05efadb"],"ts":1793138773,"cid":"poa-mainnet-1","sig":"3oV8pEAKtdDN5ibUyWmDUNNZqPqmWbWvgWPE5iKsNG8gtc9o1guoLG47xp4BVcWZBpgaTwGVaxDnmgmjcf2TZ7z6"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:46:58.413Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
