- David Schwartz revealed that the XRPL was the first blockchain to not use PoW.
- He added that the Ripple founder hired him to replace the PoW consensus model.
- XRPL uses a consensus algorithm created by Schwartz, Arthur Britto & Noah Youngs.
In a revelation on Twitter, Ripple’s CTO and one of the original XRPL designers, David Schwartz shared that the XRP Ledger (XRPL) was the first blockchain to not use proof-of-work (PoW).
Schwartz further added that Ripple founder Jed McCaleb hired him to provide a solution to replace the PoW consensus model. He tweeted out the claim in response to an inquiry made by Stefan Huber.
Yep. When Jed McCaleb first hired me back in 2011, the question he hired me to answer was whether you could swap out PoW for a distributed agreement algorithm more like PBFT and keep bitcoin's benefits.https://t.co/RRiKZyuz01—
