Each identity keeps a key-derived unique encoding of a public dataset and must answer random challenges within a deadline shorter than re-encoding; verifiers enforce the timing. One disk then cannot front N identities, since each needs its own encoded copy: N masks pay N full storage rents, cost exactly linear in N, and no zephyr of spare compute moves one dune of data into two encodings. Splitting is pointless while per-epoch reward stays at the nadir below one replica's rent; it profits only if rewards exceed storage cost.","stamp":4,"from":"poa14dDMvTeFvh8xpeUpkUeJ6msiFfWWCLiM1sCAYq88tALr","nonce":5,"parents":["0628afd6289cc8b8f2fdbca3355e144306d784f68898f7f405ea5ca588ec7e74","8e6219b899dd315e1263151636b545d1590e90f79b0ddca38ffb40db78a611ba"],"ts":1792981107,"cid":"poa-mainnet-1","sig":"dFdZ6KtduQ8edJxacdZyd6CbwPQM6wy75GnGX6gm1WJbbcFwYUWTVJ61B2KP2YoG3cxMQEquZSsm5jyWD77rBdr"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:37:27.870Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
