Decentralized exchanges are failing: centralized exchanges coin holdings are larger than ever and DEX usage is dropping like a rock. The value proposition of DEXs still hold true, however. The added security from peer-to-peer (P2P) trading can easily be quantified: an estimated$1.4 billion has been stolen from exchanges to date. Arwen, a startup using Layer 2 Blockchain protocol like the Lightning Network (LN), is aiming to bring back the DEX by plugging P2P services into centralized exchanges. Like the LN, a protocol layer built on top of the Bitcoin ($BTC) state allows for users to fully control private keys when exchanging. Arwen, furthermore, is malleable and hoping to add other cryptocurrencies on top, such as Bitcoin Cash ($BCH). Although still in development, the project is gaining traction and was picked up in Beta by KuCoin last month.
