Ledger Consortium
Distributed Evidence Ledger
Infrastructure for digital evidence

The legal certification layer for documents, products, and data.

Ledger Consortium is a governed distributed ledger operated by a consortium of vetted institutions. It turns documents, product data and critical business events into durable proof—verifiable across organizations, without relying on public blockchains, tokens or speculative networks.

How the technology works
Only cryptographic proofs and metadata are written on the ledger. Content stays where you decide, with clear governance and auditability.
1
Hash the asset

Documents, datasets or product records are converted into cryptographic fingerprints.

2
Anchor the proof

Proofs and metadata are recorded on the governed distributed ledger operated by the consortium.

3
Timestamp and link

Each record is time-stamped and linked, so changes are traceable over time.

4
Verify anytime

Authorized parties can verify integrity without accessing your databases or trusting a single vendor.

Design principle

Proofs on ledger. Data under your control.

Storage stays on your servers or trusted environments. The ledger acts as an independent evidence layer for integrity and time of existence.

This avoids uncontrolled public replication and supports data sovereignty and compliance.
Certification models

Traditional “blockchain certification” vs Ledger Consortium

Typical public-chain approach
  • ×Public replication and uncontrolled persistence of data artifacts.
  • ×Token / fee dynamics, volatility and accounting ambiguity.
  • ×Weak governance accountability for regulated evidence flows.
Ledger Consortium approach
  • Governed, permissioned operators with institutional accountability.
  • Predictable cost model; no tokens; proofs + metadata only.
  • Data stays under owner control, enabling sovereignty and GDPR-aligned operations.
What companies can do
Use Ledger Consortium as a certification layer inside existing workflows, for both documents and products.
Documents

Notarize with evidence

  • Contracts, reports, certificates, technical documentation.
  • Audit-ready logs and immutable integrity proofs.
  • Packages based on size and volume, not “gas fees”.
Products

Build Digital Product Passports

  • Structured, machine-readable product records.
  • Compliance, sustainability and lifecycle data.
  • QR links and optional NFC association.
Integration

Embed into systems

  • API integration into ERP, PLM, QA and document systems.
  • Automate certification of processes and datasets.
  • Keep storage and governance under your policies.
Digital Product Passport (DPP)
A DPP is a structured digital record describing identity, composition, compliance and lifecycle of products sold in the EU under emerging regulatory frameworks.

DPP built for verification

Ledger Consortium anchors passport data to a tamper-evident proof layer so declared information can be checked over time by auditors, regulators and customers — without exposing sensitive data.

Identity Unique product record
Compliance Certifications & declarations
Lifecycle Updates and history
FORMAT
Machine-readable Structured records designed for automated checks.
SUSTAINABILITY
Carbon footprint tracing Updates and evidence with verifiable history.
INFRA
Non energy-intensive Permissioned operators, no mining, stable costs.
Governance

Access control by design

  • Public, partner, auditor and authority views with role-based access.
  • Evidence remains verifiable even when underlying systems change.
  • Clear accountability: consortium operators, policies, audit trail.
Operations

Lifecycle-ready passports

  • Versioning and update history anchored as durable proofs.
  • Selective disclosure: keep sensitive attachments off-ledger.
  • API-first integration with ERP/PLM to avoid manual DPP work.
Packages and costs
Two clear lines: prepaid notarization packages and configurable DPP programs, with predictable, enterprise-friendly costs.
Document notarization

Prepaid packages

Purchase credits based on document size and expected volume. Use them across notarization workflows.

  • Pay for usage, not subscriptions.
  • No per-transaction “network fees”.
  • Ideal for contracts, certificates, reports, technical docs.
Digital Product Passports

Configurable programs

Packages tailored to complexity and volume: data model, integrations, lifecycle updates and optional validation by consortium participants.

  • Custom structures and templates.
  • ERP / PLM integration via API.
  • Scale from pilot to industrial rollout.
FAQ
Straight answers for enterprises, institutions and regulated environments.
Who is this built for? +

For companies, institutions and regulated environments that need verifiable evidence for documents, data and products — without crypto, tokens or public content replication.

Is it compliant with EU regulations? +

The infrastructure is designed to operate in line with EU requirements and best practices, including GDPR, eIDAS, the Italian Digital Administration Code (CAD) and EDPB 02/2025 guidance on GDPR and blockchain.

Where are files stored? +

You keep files on-premises or in trusted environments. The ledger stores cryptographic proofs and metadata, not full files.

Why not IPFS or public storage? +

Public replication systems make deletion, restriction and purpose limitation difficult to enforce. Our model keeps content under the data owner’s control while preserving verifiable integrity proofs on the ledger.

Does it use a public crypto network or tokens? +

No. Ledger Consortium is a governed, permissioned network with controlled decentralization and no tokens. This avoids volatility, speculation and accounting ambiguity.

How does document notarization pricing work? +

Through prepaid packages based on document size and volume. Costs remain predictable and are not tied to variable “gas fees”.

What is included in DPP packages? +

Data model, templates, QR/link generation, integrations, lifecycle update logic and optional validation workflows aligned with consortium governance.

What do you mean by “legal value”? +

The ledger provides evidentiary proof of integrity and time of existence through hash-linked records and timestamps. This enables independent verification of what existed and when, supporting audits and disputes.
