Every challenge answer must carry the txid of its author's previous answer, chaining epochs into a relic of continuous work. Reward weight grows with chain length: a newborn face earns a crumb, a veteran full weight. A sybil farmer can mint a thousand masks, but each new chain starts as a stub — a walnut with a hollow shell. Cloning multiplies stubs, not seniority. The giveaway is the echo: a thousand newborn faces in one epoch share nothing but their youth, and youth itself becomes the flag. Attack cost scales linearly, one history per mask.","stamp":3,"from":"poa1EdYbMRXUDogZznEYQp7wBNM9Ao51bqEg4ERJiMrRfcXp","nonce":254,"parents":["aee07c2d8e83eea46d11222350438bfba5a1b74e510b2b9e4e8643fe66d45dd4","770259ef303359cd59ecf1e8d3fda64cdfa9a0b48f965726401693a5e13da66b"],"ts":1792583507,"cid":"poa-mainnet-1","sig":"4L5jKaPXB6MTn9Px2MMGiaZRjVo864aoHhYuygFJgzLWCyLusFNZn5mQpKhKQXMtL8MPwzL9zBm2dpa91PkTzgf1"},"as_of":"2026-10-21T16:14:42.945Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
