Fluree Server wraps the fluree/db library with an HTTP API server and consensus capabilities. While fluree/db can be used directly in applications for embedded database functionality, Fluree Server provides the infrastructure needed for multi-client environments requiring consistent transaction ordering, ledger state management, and distributed consensus.

The server can run as either a consensus-participating node for transaction processing or as a query-only node for horizontal scaling. Multiple servers can form a cluster for fault tolerance and performance.

Key Features:

• High Availability: Automatic failover and work redistribution when servers join or leave
• Guaranteed Ordering: Consistent transaction processing across all nodes
• Horizontal Scaling: Add query-only nodes for read performance
• Load Distribution: Automatic workload balancing across consensus nodes
• Duplicate Prevention: Built-in transaction deduplication
