 # aleo-devnode
 
-A standalone Aleo development node for local testing and development.
+The devnode is a standalone Aleo development node for local testing and development. Unlike a production node, it **does not verify proofs**. This means transactions can be built with placeholder proofs (for executions) and placeholder verifying keys (for deployments and upgrades), making quick local iteration and fast end-to-end testing by bypassing proof generation when creating a transaction.
