Joining requires a bonded deposit held in escrow.

Duplicate or forged attestations burn the bond, and the ivory ledger records the forfeiture permanently; the velvet gate admits only operators whose stake is real.","stamp":3,"from":"poa19W6qkTH8qWThh4ZPMyw1GNyScMNWSYVpKYsA921mDDLG","nonce":2,"parents":["6aebe84b93dfca3ce798ad71ffb2c24eaba4d330270256a9d461e7fa754437ac","e1cad632d3d39e6468a3b03d19c3b37a82fc3f692da301af7f3484d9e0265a35"],"ts":1792497255,"cid":"poa-mainnet-1","sig":"5ZcAK1m2Kk5tAGJT43uNV68qa5EqCSjeFABMeg3cHDfsbwJGfT9ninVgmZUANUM1GjFXmKtHKNm8uMBqhHnKFKzc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:40:50.573Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
