Ripple CTO David Schwartz criticized the proof-of-work (PoW) algorithm used in Bitcoin and explained how the XRP Ledger is different from Bitcoin.David Schwartz spoke to TechRadar Pro and explained why XRP Ledger works with a different system than Bitcoin. According to Ripple CTO, the PoW system used in Bitcoin does not coincide with the principles of decentralization.In the Bitcoin network, the miner solves complex math problems in the shortest time receives transaction fees and block rewards. Positioning miners as intermediaries, Schwartz thinks that Bitcoin is no different from other third-party-focused systems.“A CRYPTOCURRENCY should be a one-sided market; the users want a store of value and a means of exchange,” explained Schwartz.“But what Bitcoin did was turn it into a two-sided market. Miners have historically fought for high transaction fees, because that’s their revenue. The reality is that you have another set of stakeholders who are trying to charge the highest FEES they can get away with, and that’s not much different from the way payments work at a bank.”In 2011, having identified the problems with PoW, Schwartz and former Ripple executive Jed McCaleb sought to found a new cryptocurrency on a different approach, with a greater focus on both speed and decentralization.“At the time, the philosophy for most people was that PoW was Bitcoin’s secret sauce, but the very first cracks in the foundation were beginning to show,” said Schwartz. What we were starting to think was that PoW wasn’t what was amazing about Bitcoin. It was the fact that all transaction data and transaction rules are public and that there is no central operator.”Ripple, which moved away from the PoW system at the suggestion of Jed McCaleb, started using Proof-of-Stake (PoS). According to Schwartz, with this change, XRP Ledger has become a network that operates based on coordination, not…
