Ledger Architecture
Preserve history reliably
The ledger architecture connects action, object, state, responsibility, review, and correction in a continuously traceable and technically verifiable process history.
Understand the Ledger Architecture →420+ connects real work with products, batches, materials, rooms, equipment, checks, and measurements. The operational digital twin makes recorded operations usable for process guidance, analysis, and controlled development.
Real work becomes digitally usable.
Operational digital twin
People perform tasks involving real products, batches, materials, rooms, and equipment. 420+ connects the recorded actions to the affected operation, current state, location, and responsible role.
An operational digital representation grows from recorded executions. Its scope depends on which operations, events, and results are included. This foundation can be used to prepare next steps and compare suitable process histories.
Modernization without loss of control: responsibility remains with people, while practical experience becomes usable in the system.
How 420+ works
Work, resources, evidence, and operations describe four connected areas of responsibility in the platform concept. An SOP task may concern batch state, material consumption, equipment references, and review at the same time. We clarify which modules and connections will be provided for your workflow based on the specific use case.
From practice
“420+ does more than represent what happens in an operation. The system connects the affected objects, their state, and the responsibility behind every change.”
Hannes Schubert · Founder and Managing Director of 420+
This turns real work into a digital operational reality that guides the ongoing process and makes its experience usable for later decisions.
About the companyFrom operational state to insight
The current state does not explain how it came about. A connected history keeps execution, measurements, resource effects, reviews, and decisions accessible. The four System Design pages explain different tasks on this foundation.

Understand the Ledger Architecture →Process Mining
Process Mining compares actual process histories across SOPs, batches, sensor data, and material and resource use. Process variants and recurring relationships become visible and are distilled into a few relevant findings.
Explore Process Mining →Process Intelligence
Process Intelligence defines clear learning tasks from recurring findings and connects reviewed experience to its provenance, context, and scope. Operational DNA develops step by step.
Explore Process Intelligence →Industry 5.0
Industry 5.0 brings operational DNA into the specific work situation. Relevant relationships and information support substantive assessment; decisions and responsibility remain with people.
Understand Industry 5.0 →Real work creates digital operational reality. Its history produces insight. Reviewed experience becomes effective in work again.
Target markets
The ten target markets share a basic idea: connect operational objects to provenance, state, location, task, and evidence. The required rules, roles, and approvals must be defined separately for each use case; a shared architecture does not imply blanket market authorization.
Provenance, inventory, processing, review, and release remain connected throughout the complete product and batch history.
Composition, production batch, quality status, documents, and product information are managed in a traceable operational context.
Product, application, location, quantity, responsible role, and required evidence remain connected.
The same operational digital twin architecture can be configured for additional products, teams, and sites. The substantive rules, roles, approvals, and evidence for each application field remain distinct.
Operations & data sovereignty
The operational digital twin contains key operational relationships. Hosting, infrastructure control, and your own portals therefore belong in planning your deployment. The availability and scope of the following operating options are agreed on a project-specific basis.
Encryption: Data at rest is protected using a hybrid combination of AES and ECC; data in transit uses TLS 1.3.
Your real operation
In the demo, we guide a specific operation through 420+: with the roles, tasks, products or batches, materials, rooms, equipment, reviews, and approvals involved. This shows how an operational digital twin emerges from the actual workflow and which analyses can build on it.
