eIDAS v2 - Qualified Electronic Ledgers (Ledger)

This certification is designed for organizations providing or operating a distributed ledger service in environments requiring a high level of proof, trust, and long-term preservation. Becoming a Qualified Trust Service Provider (QTSP) within this scope is a strategic asset for:

• Blockchain and DLT Providers / Web3 Ecosystem Players: Teams operating shared ledgers who wish to transform their decentralized technological solutions into a legally recognized trusted third party at the European level.
• Supply Chain and Logistics Operators: Industries requiring flawless and legally enforceable traceability (e.g., Digital Product Passport (DPP), raw materials tracking).
• The Financial and Banking Sector: Institutions managing transactions, digital assets, or smart contracts that demand indisputable proof of priority and sequential order.
• Public and State Authorities: Agencies responsible for managing administrative, land, or legal public registries.
• Critical Infrastructure and Energy Operators: Entities handling the certification of origin for green energy, carbon credits, or grid transactions.

For tech and industrial players, the eIDAS v2 qualification of an electronic ledger addresses 4 major strategic challenges:

• The Legal Presumption of Integrity (Automatic Legal Effect): In accordance with the eIDAS v2 Regulation, data recorded in a qualified electronic ledger enjoys a unique presumption of the accuracy of the date, time, and sequential order of the recording. In the event of litigation, the burden of proof is reversed: it is up to the opposing party to prove any hypothetical alteration of the ledger.
• Automatic Cross-Border Recognition: Qualification guarantees the legal and technical interoperability of the ledger across all 27 EU Member States. A recording certified in France is natively enforceable before any European administration or court of law.
• A Passport to Regulated and Public Markets: Listing on the European Trusted List (EUTL) removes entry barriers when contracting with the public sector, finance, healthcare, or heavy industry, where eIDAS v2 compliance is becoming a prerequisite for procurement tenders.
• Technological Immunity and Evidence Permanence: By validating the consensus architecture and cryptographic protections against strict ISO standards, certification protects the operator against immutability flaws and guarantees the independent verification of long-term evidence, even if the underlying infrastructure undergoes technical evolution.
  
   

The eIDAS v2 framework defines strict requirements to guarantee the reliability and continuity of the service. The provider must demonstrate:

• Controlled governance of the service (processes, responsibilities, supervision);
• Robust security covering the distributed infrastructure and cryptographic mechanisms;
• Full traceability of the operations recorded in the ledger;
• Mechanisms guaranteeing immutability and proof of data integrity;
• Clear methods ensuring long-term preservation and independent verification of evidence.

The service is assessed based on European and international standards for Trust Service Providers (TSPs):

The service is assessed based on European and international standards for Trust Service Providers (TSPs):The technical ISO (23257 / 23635) and eIDAS v2 frameworks notably mandate:

• Consensus mechanisms preventing retroactive modification (absolute immutability).
• Secure time-stamping of blocks (typically backed by an ETSI EN 319 422 qualified time stamp).
• Traceable and publicly verifiable logging.
• Mathematically provable integrity without depending on an unmanaged centralized third party.
• High-level protection of the cryptographic keys used for transactions.

Note: Certification attests to compliance with technical standards. Qualification is subsequently granted by the national supervisory authority (such as ANSSI in France), enabling official entry into the European Trusted List (EUTL).
