CEN/TS 18264:2026 – Policy and Security Requirements on Trust Services on Electronic Ledgers

Full Title: Policy and security requirements on trust services on electronic ledgers

CEN/TS 18264:2026 sets out policy, functional, and security requirements specifically tailored for qualified trust services operating on electronic ledgers, such as blockchains and distributed ledgers. This specification responds to the legal updates in such frameworks as the amended eIDAS Regulation (EU) 2024/1183, setting a reference point for the governance, management, and assurance of trust services that record and secure digital transactions or data.

Scope & Purpose:

  • Defines mandatory policy and security requirements for the operation of trust services supporting electronic ledgers.
  • Captures provisions necessary for the orderly issuance, storage, and verification of electronic records with traceable origins and tamper-evident histories.
  • Ensures records are immutably and sequentially stored, with any attempts at modification immediately detectable.

Key Requirements and Specifications:

  • Ledger architecture: Specifies both centralized and distributed ledger models, while requiring that all managed ledgers support traceable, secure, and chronologically ordered data storage.
  • Permission Models: Establishes clearly defined public-permissioned and private-permissioned models, excluding permissionless ledgers from scope, as these cannot meet regulatory-based trust requirements.
  • Functional Goals: Trust providers must:
    • Establish the origin of each data record via authenticated access and cryptographic techniques
    • Guarantee chronological ordering using consensus and block structuring
    • Employ cryptographic hash chains for data immutability
    • Detect any data modification instantly to preserve integrity
    • Support proof of existence through qualified timestamping (per ETSI EN 319 421), where strict temporal accuracy is required
  • Service Management & Compliance: Requires draft and maintenance of practice statements and policies, detailed asset and access management, physical and environmental controls, incident and continuity planning, and evidence collection protocols.
  • Interoperability & Data Preservation: Encourages integration with preservation services or components to maintain long-term cryptographic resilience (per ETSI TS 119 511) and supports requirements for migration and cross-system interoperability.

Who Needs to Comply:

  • Qualified Trust Service Providers (TSPs) offering electronic ledger services in regulated industries (finance, legal, public administration, supply chain, digital identity management, and more)
  • IT solution providers integrating distributed ledger technology into enterprise systems
  • Auditors, compliance officers, and digital identity managers assessing or certifying trust service operations against EU standards

Practical Implications:

  • Adoption of this standard is a clear pathway for organizations seeking eIDAS-compliant, trusted ledger-based services for critical data and transaction management.
  • Implementation involves policy updates, system enhancements (to incorporate consensus, access controls, cryptographic protection, auditing capabilities), and comprehensive documentary evidence to support internal and external audits.

Notable Advances:

  • Brings services in line with the evolving eIDAS 2 requirements around qualified electronic ledgers
  • Standardizes terminology (per ISO/IEC blockchain vocabularies)
  • Provides detailed guidance on the intersection of governance, technical security, and operational practice

Key highlights:

  • Provides policy and operational guidance for trust services operating electronic ledgers
  • Mandates cryptographic integrity, auditable data sequences, and clear access controls
  • Aligns European trust service providers with new regulatory and conformity assessment frameworks
