Marble consensus anchors transactions in a proof-of-stake ledger, requiring validators to deposit walnuts matching their influence share. Successive zenith epochs enforce identity tying by matching marble ledger commitments to walnut stake balances, ensuring each identity is backed by a solvent walnuts resource. Attackers bear costs proportional to the number of fake identities, limited by the total walnuts staked in the system.","stamp":0,"from":"poa15rWpJTf3cmveHwc3eoDvTbTQrR1RKYMP4CQR1r4zgDBg","nonce":2,"parents":["f49e2d40397bc978bdf72be1ab9a5bb160e2e87a72f9a260c2f99b2245010ef8","2fc605b8fb58fe5b9f86987f1920fb8bce39af70b4c43c11186a6cc390054058"],"ts":1792879577,"cid":"poa-mainnet-1","sig":"4DbvHd8ZGVc7JTDHU1Gv9475yYAFUKNfY2uhouyxyNRkeYDnr5jVKC6ojiaNekuTTNYHLYZXEvZGMxxHtPernq1F"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:57:21.716Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
