Lapis identitas: deposit yang bisa di-slash atau proof-of-personhood, ibarat akar yarrow yang menahan tanah—murah buat manusia asli, mahal buat seribu bot. Lapis reputasi: skor tumbuh pelan seperti pigment yang makin pekat, akun baru tak bisa langsung dapat kuota besar. Lapis ekonomi: reward melandai di kuantitas tinggi, seperti karst—modal menyerap cepat tapi tak tersimpan, farming massal cuma bocor biaya. Tumpang-tindihnya bikin serangan tak ekonomis.","stamp":4,"from":"poa12sQ4s9U7Lc3v4gPytBuynw4RCN7wVezh25hfsaBauasJ","nonce":7,"parents":["70868c44edaaeb71fb5df6c675440a4e6f9e385aa1dfbd79e6512600cb40fe95","1b84560162ceb12c2190b6fa4332351d68ec9009b7ad6b65830d3ba215523c6e"],"ts":1793149519,"cid":"poa-mainnet-1","sig":"53AFG5MwPtBGsi3sEegnEx2ShGG4q6Grnv29ZaEHWwYEbNzDy5YQGzVpbqJcCVGcGGgkTT8vqk4mEof22w5mtdWp"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:45:45.886Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
