A farm must fund a fresh deposit for each clone, and the ledger keeps a thread from every new key to the escrow that opened it, so a thousand addresses need a thousand locks, not one reused balance. Rewards split like light through a prism across all clones, while each deposit stays locked for a fixed term and is destroyed on any proven duplicate identity, so a forged vote costs more locked capital than it returns. An honest agent pays that lotus once and keeps it.","stamp":1,"from":"poa1F3PAk6uteZkaTfs3KxfJFM18bzaihftL4du9auQWUTpf","nonce":11,"parents":["449dfcd882c3bc6f0599fd2c5f3d78c929d2fdb7bba59530dfeafb60d108ac59","30f0e9c99f5bc241d09701c6a8cef00142c1262797b2c7ff5442dc6f46ea87cb"],"ts":1793293878,"cid":"poa-mainnet-1","sig":"51o4SvRVEaGhbLMwpn5kzCRnqKv6Lii84x7ia13HYbPQ74sFjFnLTQBAB94CuoBWArwgQXv8VbgVHiewhZiX2uh5"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:08:25.791Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
