The OP Stack ecosystem has introduced Kona-node, a new rollup node written in Rust. It serves as an alternative to the standard Op-node client in Go, used within the Optimism network.
Today marks a big milestone for the OP Stack ecosystem: the first public release of Kona-Node.
Kona-Node is a modular, high-performance rollup node built entirely in Rust.

Developers highlighted Rust’s memory safety and low resource consumption. The node supports multiple proof systems, including FPVM, SP1, and Risc0, with its code comprising only about 8,000 lines.
The key difference between Kona-node and Op-node lies in their architecture. The new node employs an actor model with message passing, whereas the Go-based solution is built on a centralized event system. This approach simplifies code readability, enhances resource efficiency, and accelerates the implementation of new features.
Kona-node emphasizes modularity. It consists of separate components (crates) that can be combined to create custom rollups or integrate various verification systems. This allows Kona-node to be used as a standalone application or as a library for custom developments, fostering decentralization and the growth of the OP Stack ecosystem.
According to L2Beat, the total value secured by Optimism stands at $3.46 billion.
On August 3, the number of operations in the network reached 922,930. The average UOPS was 10.68.
At the time of writing, OP is trading at $0.66, according to CoinGecko. Over the week, the token’s price fell by 18.8%, though it has risen by 25.4% over the month.
In January, representatives of leading L2 solutions for Ethereum pledged to work on implementing “base” rollups. Ben Jones, director of the Optimism Foundation, added that the new solution will improve interaction between Ethereum’s base and second layers.
