Sky Rune posted to discuss building an open-source alternative to Hyperliquid

ChainCatcher news, Rune, co-founder of Sky (formerly MakerDAO), stated on the X platform that he thinks Hyperliquid is a great concept and a well-executed product. However, he wonders what the best option would be if someone wanted to replicate this concept using an open-source stack that has built-in security and has been tested in real-world scenarios. Is it the OP/arbi stack? Or are there any options that can provide better performance without compromising security and reliability?
