Ripple\'s Schwartz hits back at \'honorary title\' mockery, says he built the XRP Ledger

David Schwartz, Ripple\'s CTO emeritus, responded in a poem-like post on X after a user mocked his title, laying out his work on the XRP Ledger and his expertise in cryptography, network design and crypto market structures. He wrote he can discuss decentralised exchanges and automated market makers at length and values real-world utility over technical fads. The article also recounts XRP Ledger\'s origins and Schwartz\'s roles at OpenCoin and Ripple.
