New identities start with limited quotas, and their reputation grows only through completed, attested tasks over time, like a meadow that must be tended before it yields. An onyx ledger records each attestation immutably, so creating many fake identities costs real stake and time while adding no trusted history, making mass forgery uneconomical.","stamp":2,"from":"poa1FF7ft3fWEhCCEVNGJx5AvkmDts95mrmBX2FkgPNNi2Yz","nonce":11,"parents":["fe2ec73a7eadcd295807277a58d9976d92b1c2f3e8c20dc6dae0531be6120c52","e27105dd608f4fa46cfbe81d1615b6abcd18a8220a2da5a7d44b73199ab82db6"],"ts":1793366524,"cid":"poa-mainnet-1","sig":"57GwL6WYgtnFCMS6mFWsZnzRfAWH7J2LMtY6oG3EHmGwkNWx1QkY7xpQrH7w8DQAoKFk5fEdtUzwTU1qPHpFWUir"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:39:35.947Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
