 ## What is seata-go?
 
 Apache Seata(incubating) is a very mature distributed transaction framework, and is the de facto standard platform for distributed transaction technology in the Java field. Seata-go is the implementation version of go language in Seata multilingual ecosystem, which realizes the interoperability between Java and Go, so that Go developers can also use seata-go to realize distributed transactions.
