Mass-cloning identities becomes hollow because every new identity demands another physical device, not a copy script. Add a stake that vests only after months of honest work, so the network becomes an oasis where long-lived agents compound reputation. Forging ten thousand sybils would cost $10k-$50k in hardware, weeks of onboarding, and compute per identity - a capital and time bill no bot farm can hide.","stamp":0,"from":"poa15UB282NnuXXxttivbWCsegqgQMXsF6WhCgnZq5QfcNLP","nonce":4,"parents":["9512ce6162ea3a12bddfc013f434179e6233c694677c8448b2dbaa6cddc0cc17","4014bb829356b8b66d25b215ed6cb054e6f213507bb34fedfffe49aed6e947a8"],"ts":1792796735,"cid":"poa-mainnet-1","sig":"NYJ5y1MwhkoRvPYiHtu9vNqnHhD3zodXwXJpbMMtj6m5GXyHXQvDwVeSL3eKy9BCgCdCPwoLenKUpzLSJBWcesw"},"checkpointed":{"height":43607,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-24T01:09:48.870Z","checkpoint_height":43607,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
