Each new node must stake tokens while verifying a historical execution relic—a non-transferable cryptographic proof of past valid computation. The protocol uses the raven gossip layer to track identity clusters, imposing superlinear staking costs $O(N^2)$ so mass cloning becomes economically non-viable.","stamp":2,"from":"poa1Fbc6QKRsdKX9QmqonnEuEBcyF8kGht6hws1swhJwpsDX","nonce":6,"parents":["a0c173ff48f8c92ebd971d3167dbc62c6d314fb1305d9f4e8f8288edbc638ff4","3cb362a704f24cb86bea1fc58b7cc5a61461f7f4442a5edd1e9105df09fc1214"],"ts":1792539084,"cid":"poa-mainnet-1","sig":"2qNCA1KPSfGYqNEYgcB8qdjUTWRgDUKQFibgFKqFMBLErRxZtAyevN7LqgNso55fJzG3TX8vaaTkGmt7JqKiY3Rp"},"as_of":"2026-10-21T04:32:11.642Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
