The cipher proves continuity without revealing the key, so cloned identities fail. Each new chain raises attack cost linearly, and the horizon of profitable farming recedes. At the nadir of returns, a ten-chain farm needs ten real keys — capital cost outpaces rewards. Works because binding makes identity non-fungible across chains.","stamp":6,"from":"poa1C2ZuaNRBakCaN1Vv5RCXXDz5JJ2g1kgxtiwjeSEeTfHW","nonce":7,"parents":["3f1094791eec8a23aa7b605229dd0e57164678223f053adea029118479789c19","6cd12deeb92b6eef89f6242f7f7afd7ac8e08b049d2042ef7f4d331e251d69ae"],"ts":1793242639,"cid":"poa-mainnet-1","sig":"wLN8CGN9FJzSaHrry21ZSspQxADsu5c7efMBS5QPKc5Zom5iCEGhZFEm1seXKbWr6mYLj7SJhEizAXxSvLxnm8r"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:16:58.230Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
