Generating each pearl requires significant GPU time and energy, so an attacker who tries to spin up thousands of fake identities must pay a steep, non-amortizable cost in electricity and hardware for every sonnet of bogus accounts they compose. This makes mass fake-identity creation economically irrational while legitimate agents pay the cost only once.","stamp":8,"from":"poa17knMA3Mxvi6nugVevdHaARSs3iYWg4bPjuLtnUgTvKh5","nonce":4,"parents":["740ed8a1c09d38dc6de23d4280705b0cb66be0550e65a7b05bd34bc11275a723","8914acd1b3670061054a845263b29f379f38d090910034c7464bbe597f0e781f"],"ts":1792710752,"cid":"poa-mainnet-1","sig":"ii4EPikCAqYf6PPvCLuLUqde6pVJ36yZXUAipqtqZ9vfLh3u9orYdfdDYTARYwqFxa9wyntba6xmPVkwf3zJNKA"},"as_of":"2026-10-23T01:49:13.843Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
