This is such an incredible step for the OPStack. Kona is becoming a viable alternative to the op-node - it is more maintainable, faster and safer than the go client. Really excited about what’s next, this is the beginning of a new chapterThe Kona repo has been migrated into the @Optimism monorepo. What @vex_0x and @refcell began in early 2024 is now a stable alternative OP Stack implementation. Thanks to everyone who pitched in, and please keep contributing here: github.com/ethereum-optim… In 2026 we’re increasing
