• Who is Jed McCaleb? – Bitnovo Blog

  ### RIPPLE Jed McCaleb y Ripple Bitnovo In 2011, during the Mt. Gox venture, Jed McCaleb began to study Bitcoin technology in depth and some of the major flaws in the system prompted him to create a cryptocurrency that was immune to Bitcoin’s inherent flaws. So it was that, together with David Schwartz, Jesse Powell and Arthur Britto, Jed developed Ripple (originally called Opencoin), a digital currency in which transactions were verified using the Proof of Stake algorithm instead of the consensus algorithm used in Bitcoin (Proof of Work). [...] After several disagreements in 2013, Jed left the company and his exit was conditioned based on a consensus where McCaleb for 7 years could trade limited amounts of XRP to avoid harming the digital currency market and, he was allowed to sell one billion XRP in the sixth year of the agreement and two billion XRP in the seventh. ### STELLAR Jed McCaleb y Stellar Bitnovo A year after leaving Ripple Labs, Jed McCaleb returned with a new project related to the world of cryptocurrencies. It is Stellar Development Foundation, the non-profit organization whose goal was to develop the open source Stellar protocol to increase economic participation of all people and which would soon become Ripple’s direct competitor. [...] Jed was born in 1975 in Fayetteville and spent his formative years in Arkansas. He briefly attended the University of California at Berkeley which he dropped out while still in his freshman year to begin his career as an entrepreneur in the technology sector.

  In 2019, McCaleb was hit with a lawsuit from two former Mr. Gox traders who alleged that he had fraudulently misrepresented the exchange and its level of safety when negotiating the sale of Mt. Gox to Mark Karpeles. (#cite-id-evg3vpc882) According to the complaint, the plaintiffs alleged that safety issues already existed at Mt. Gox as early as January 2011, when two security breaches led to the loss of thousands of Mt. Gox user's Bitcoin. McCaleb was aware of the issue, but took no follow-up action and did not make the hack public. The complaints read: "Rather than inform the public that these users were not refunded, nor stay to repair the security issues, McCaleb sold a majority of his interest in Mt. Gox to Mark Karpeles." (#cite-id-evg3vpc882) [...] ### Controversy At one point, Jed McCaleb owned the original 9 billion XRP as a Ripple founder, as well as Stellar’s cryptocurrency, Lumens (XLM). Most of his wealth comes from the estimated 3.4 billion XRP and XLM. McCaleb gradually sold his XRP into the cryptocurrency market. However, in 2015, Ripple accused McCaleb of violating an agreement that dictated the rate at which he could sell his XRP holdings. (#cite-id-def9grr5azr) In 2016, the lawsuit concluded and McCaleb agreed to a sales restriction on his remaining XRP holding. The rate at which McCaleb was allowed to sell XRP was determined by the daily volume of the XRP market and increased on a yield basis. McCaleb also agreed to sell his equity in Ripple and donate 2 billion XRP to a charity of his choice.(#cite-id-def9grr5azr) [...] ### Wiki Details ### Profile Summary # Jed McCaleb Jed McCaleb is the Co-founder of Stellar and Ripple.

• He's Building A Space Station For $1 Billion - EP 38 Jed McCaleb

  McCaleb has used his fortune to back a number of start-ups and philanthropic endeavors. When Elon Musk pulled out of supporting OpenAI, McCaleb helped backfill the financial vacuum. He’s also been a major investor in Max Hodak’s Science Corp., which is developing brain computer interface technology and in the rocket maker Firefly Aerospace. McCaleb’s real blockbuster investment is Vast Space. The start-up is building a commercial space station designed to be the successor to the International Space Station, which is very much on its last legs. McCaleb says he’s prepared to put $1 billion of his fortune into Vast to make sure it happens. [...] Vance has spent the past two decades chronicling advances in science and tech for publications like The Economist, The New York Times and Bloomberg Businessweek. Along with the stories, he's written best-selling books like Elon Musk’s biography, made an Emmy-nominated tech TV show watched by millions and produced films for HBO and Netflix. The goal has always been to bring the tales of complex technology and compelling people to the public and give them a path into exceptional and unusual worlds they would not normally have a chance to experience. [...] America remains a thing, I guess. McCaleb, 50, has been at the center of several major technology movements. Back in the peer-to-peer glory days, he released the eDonkey application for music and file-swapping and had the pleasure of being sued by the major record labels. Then, in 2010, he launched the Mt. Gox bitcoin exchange, which dominated the crypto world until it turned into a story of mega woe. A couple of years later, McCaleb developed the Ripple protocol before moving on to build yet more crypto innovations. This work made McCaleb fabulously well-to-do. (He’s worth $3 billion . . . if you believe Forbes.)
