What is a block template in Kaspa solo mining?

A block template is the package of work a Kaspa node hands to your mining device — it defines exactly what puzzle needs to be solved before a new block can be added to the DAG. The DAG (directed acyclic graph) is Kaspa's version of a blockchain, where blocks can be produced in parallel rather than one at a time. Each template comes with a difficulty threshold set by the entire network, meaning your device must meet that exact standard for your finished block to be immediately accepted and broadcast to all other nodes. For a beginner, the key point is that the template is the starting gun: without it, your hardware has nothing to mine, and once you solve it correctly, your block joins the live network right away.
