Overview

The first release of new implementation of the Cardano node

• Represents complete rewrite compared to cardano-sl

• Has 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

• Compatible with the Byron mainnet. It can validate blocks from Ouroboros Classic and create blocks after the BFT hard fork

• The node no longer incorporates wallet or explorer functionality. The wallet backend and explorer backend are separate components; these run in separate external processes that communicate with the node via local IPC

Platforms

• Linux 64-bit
