Vitalik emphasized the importance of client diversification for decentralization in his blog. Currently, there are multiple client implementations based on Go, Rust, C# and Java.The diversification of clients is also the expectation of the OP stack. Currently, the official development of various services in the OP stack is mainly based on Go. At the same time, we have seen optimism-rs promoted by refcell, and most of the OP stack has been implemented with Rust. Serve. With the arrival of Java 21 (virtual thread, structured concurrency), combined with GraalVM native, it is also a very good choice to use Java to build the OP stack.\n\n## Roadmap\nCurrently, we have implemented an initial version of an op-node that supports bedrock (missing optional p2p, missing sequencer mode). We hope to continue to improve hildr-node, while continuing to implement hildr-batcher, hildr-proposer, etc.", "logoImgData": {}, "projectGithub": "optimism-java", "projectTwitter": "OptimismJ10684"}
