One audit trail.
No database to trust.
Every action from every party lands on the same tamper-evident record, signed the moment it happens. No single owner, no gatekeeper, and nothing anyone can quietly edit later.
Trusted by enterprises and governments across Europe
mintBlue turned our nightmare of invoice exchanges into a dream of automation. Now we strive to make taxation less of a headache for everyone involved.

Real-time Taxation
See it work, end to end.
One invoice triggers identity verification, the rules run, and the value moves, in a single flow.
- 01
Event Triggers
Vendor issues an invoice. The event is recorded in the Operational Data Store with a cryptographic timestamp. Every party sees the same data in real time.
- 02
Identity Verifies
Self-Sovereign Identity confirms the legal signature, authorised party, and valid credential. Legally binding proof without a central authority.
- 03
Logic Executes
The State Machine calculates VAT, validates against business rules, and triggers settlement. Settlement runs without manual review or delays.
- 04
Value Transfers
The Event Stream processes payment, notifies the Tax Administration, and updates all parties automatically. From 90-day filing to real-time compliance.

Reconciliation in the pilot flow
Four pillars on a secure foundation.
Each pillar works independently. Together they eliminate integration overhead. Security and sovereignty underpin all four.
The Integration Tax You're Paying
Your team spends 60% of development time integrating systems. Data in one place. Identity in another. Business logic scattered. Value transfer manual. Every project means another integration, another vendor, another point of failure.
One infrastructure changes the equation.
Traditional Approach
- Data layer (database)
- Identity layer (auth provider)
- Logic layer (application code)
- Value layer (payment processor)
- Integration costs: 40-60% of budget
One infrastructure on open protocols.
- One layer. Four capabilities.
- Data, identity, logic, value unified
- Self-executing business rules
- Integration costs: -80%
For Architects: How We Built This
The technical decisions that make convergence possible.
01
Three-Layer Storage
L1: Ordering (immutable). L2: Compute (distributed). L3: Sovereign (your control). Data stays on European nodes and remains deletable for GDPR; only proofs anchor to the immutable layer.
02
Event-Driven Core
Every action is an event: events trigger logic, logic updates state, and state changes generate new events. Everything composes.
03
Zero Vendor Lock-in
The protocols we build on are open and the audit layer belongs to nobody. Any provider can retrieve your data from it. Leaving mintBlue is guaranteed by the architecture itself, so you never depend on a contract clause to get out.
04
Single Reference Architecture
One event, multiple uses. No data duplication. No reconciliation. Every system reads from the same source of truth.
How mintBlue Compares
| Capability | Traditional | mintBlue |
|---|---|---|
| Data Sharing | Centralised databases with API gateways. Each party maintains a copy. Reconciliation required. | Shared operational data store. Every party sees the same truth. Zero reconciliation. |
| Identity & Trust | Federated identity providers. Trust depends on central authority. Limited legal standing. | Self-Sovereign Identity. Cryptographic proof. eIDAS-compliant. Legally binding. |
| Business Logic | Embedded in application code. Scattered across services. Manual enforcement. | State Machines execute rules automatically. Define once, deploy everywhere. |
| Value Transfer | Separate payment processors. Manual invoicing. 30-90 day settlement cycles. | Programmable value transfer. Settlement in seconds. Integrated with business logic. |
| Compliance | Periodic audits. Manual reporting. Retrospective enforcement. | Real-time compliance. Automatic reporting. Built-in regulatory frameworks. |
| Integration Cost | 40-60% of development budget. New vendor per capability. Point-to-point connections. | Single infrastructure layer. Four capabilities unified. Up to 80% cost reduction. |
Comparisons based on typical enterprise integration patterns. Actual results vary by implementation.
European Data Spaces Ready
European governments are building sector-specific Data Spaces for health, finance, mobility, and industry. mintBlue delivers what Data Spaces require: sovereign multi-party data sharing, verifiable trust, and compliance infrastructure through production-ready architecture.
