Oyster is the new paradigm for the internet economy that breaks the stalemate between advertisers and ad blockers. Website owners add the one line Oyster code to their site HTML to turn their visitors into treasure hunters that search for Oyster Pearls: the PRL token. Treasure hunting means a visitor’s browser performs light Proof of Work micro-puzzles that discover embedded PRL in the encrypted data maps of uploaded files. Storage users spend PRL to reliably and anonymously store their data as website visitors’ browsers maintain the retention of such data whilst hunting for the spent PRL.
