Ledgerune

Ledgerune is more than a simple balance plugin. Instead of treating money as a number that can be freely modified, every financial operation is recorded as an immutable transaction with corresponding ledger entries.

Payments, fees, taxes, marketplace purchases, loans, payrolls, auctions, investments, and administrative operations are committed atomically, providing a reliable financial foundation for small servers and large multi-server networks.

Why Ledgerune?

Most economy plugins store a player's balance as a mutable value. Ledgerune uses a proper financial ledger where every balance change has a traceable origin.

This architecture provides:

• Immutable transaction history
• Atomic debit, credit, fee, and tax operations
• Double-spend protection
• Idempotent transaction processing
• Append-only, hash-chained audit logs
• Persistent recovery state for complex operations
• Safe asynchronous database access
• Multi-server coordination through shared SQL databases

If an operation fails, its related changes are rolled back together.
