A Cardano Mini Protocols implementation in Java

Overview

Yaci is a Java-based Cardano mini-protocol implementation that allows users to connect to a remote or local Cardano node and interact with it in a variety of ways. With Yaci's simple APIs, you can listen to incoming blocks in real-time, fetch previous blocks, query information from a local node, monitor the local mempool, and submit transactions to a local node.
