Ever wondered how to communicate directly to your Cardano node? Where you bound to the cardano-cli? Did you wrap it around your preferred language? Now I have a new way. Talk directly to the node. The node follows a network specification on how it communicates to other nodes and clients. You can implement that specification and talk directly to the node.

I have done it, and documented the effort along the process. Now on this website there is a new tab Education where I store documents about dealing with Cardano. Starting today, it includes the Ouroboros-network: Local State Query mini-protocol documentation .
