future of OGCATS

Random number from Chainlink https://dashboard.tenderly.co/tx/polygon/0xde5e65da5017c7cb852ab7e21aaad54ee638f2cae7d68c4cc1697c59f141cc2b/logs

too big to work with, cut it to 18 decimals. shuffle an array from 0–1000 using it as seed.


returning: 786,555,370,779,622,375,418,816,598,273,905,822,503,130,…. etc

Hash of the original images (unrandomized). Note that the rare ones are first 23!

PS. Q.E.D. or QED is an initialism of the Latin phrase quod erat demonstrandum, meaning “which was to be demonstrated”. Literally it states “what was to be shown”.[1] Traditionally, the abbreviation is placed at the end of mathematical proofs and philosophical arguments in print publications, to indicate that the proof or the argument is complete.

meaning the randomization process was random and we didn’t keep the rare ones for ourselves.
