Complete rewrite compared to previous cardano-sl series.
-
New modular design. The cardano-node is the top level for the node and aggregates the other components from other packages: consensus, ledger and networking, with configuration, CLI, logging and monitoring.
-
The node no longer incorporates wallet or explorer functionality. The wallet backend and explorer backend are separate components that run in separate external processes that communicate with the node via local IPC.
