V1 is now considered legacy and will only receive critical security updates. We strongly encourage all users to migrate to V2 for the latest features, performance improvements, and ongoing support. For information on V1, please refer to the lts/v1 branch. Introduction We have tools to \"explore\" the Cardano blockchain, which are useful when you know what you're looking for. We argue that there's a different, complementary use-case which is to \"observe\" the blockchain and react to particular event patterns. Oura is a rust-native implementation of a pipeline that connects to the tip of a Cardano node through a combination of Ouroboros mini-protocol (using either a unix socket or tcp bearer), filters the events that match a particular pattern and then submits a succinct, self-contained payload to pluggable observers called \"sinks\". Check our documentation for detailed information on how to start working with Oura . Etymology The name of the tool is inspired by the tail command available in unix-like systems which is used to display the tail end of a text file or piped data. Cardano's consensus protocol name, Ouroboros , is a reference to the ancient symbol depicting a serpent or dragon eating its own tail, which means \"tail eating\". \"Oura\" is the ancient greek word for \"tail\".
