The Problem

Compliance systems were not designed for provable evidence.

When regulators or auditors request proof, organizations must reconstruct events from systems that were never designed to produce cryptographically verifiable evidence.

Mutable audit logs

Logs stored in mutable databases can be altered, deleted, or corrupted without any trace of modification.

Fragmented systems

Evidence scattered across disconnected systems with no shared timeline or unified source of truth.

Manual evidence gathering

Weeks of manual forensic analysis to reconstruct event timelines when auditors or regulators request proof.

No AI automation path

Non-verifiable event records that AI agents cannot reliably reason about for automated compliance checks.

The Solution

VeriLedger creates a verifiable evidence layer.

A distributed ledger infrastructure purpose-built for recording regulatory and operational evidence. Every relevant event becomes a cryptographically sealed record with provable chronology and tamper detection.

sealed-evidence.json
{
"id": "ev_2026_001_kyc_9f3a",
"event": "kyc.verification.completed",
"hash": "sha256:e3b0c44298fc1c14...",
"prev_hash": "sha256:7f83b1657ff1fc53...",
"signature": "ed25519:MFkwEwYHKoZI...",
"tsa_token": "rfc3161:MIIEpgYJKoZI...",
"merkle_proof": ["0x4e2d...", "0xa1f3..."]
}

Each evidence record in VeriLedger contains everything needed for independent verification: the event data, its cryptographic hash linked to the previous record, a digital signature from the issuing system, and a qualified timestamp from an external authority.

Immutable Signed Timestamped Chain-linked Merkle-anchored

Append-only. Records cannot be modified or deleted after creation.

Provable chronology. RFC 3161 qualified timestamps from external TSAs.

Tamper detection. Any modification breaks the hash chain.

The Product

Three layers of verifiable evidence.

A technical platform, not just a blockchain. Three distinct layers that work together to capture, enrich, and expose verifiable evidence.

LAYER 01

Evidence Ledger

A permissioned distributed ledger optimized for audit events, regulatory evidence, and compliance checkpoints.

  • SHA-256 hash chains
  • Ed25519 digital signatures
  • RFC 3161 qualified timestamps
  • Merkle tree anchoring

LAYER 02

Evidence Context Layer

Off-chain infrastructure that enriches records with structured metadata, compliance rules, and regulatory context.

  • Structured regulatory metadata
  • Compliance rule references
  • Document integrity proofs
  • ISO / GDPR framework mapping

LAYER 03

MCP Server

A Model Context Protocol server that allows AI agents to query evidence, reason about compliance, and generate audit reports.

  • Model Context Protocol
  • Natural language evidence queries
  • Automated compliance reporting
  • Agent-to-ledger integration

How It Works

From event to verifiable evidence.

01

Event Capture

Enterprise systems emit compliance events via webhooks, CDC, or REST API.

02

Hash & Sign

SHA-256 hash computed and Ed25519 digital signature applied to the event.

03

Timestamp

RFC 3161 qualified timestamp obtained from an external TSA authority.

04

Chain

Record appended to the hash-chained ledger with reference to previous hash.

05

Anchor

Periodic Merkle root computation and external anchoring for batch verification.

06

Query

Evidence retrievable via REST API or MCP server for AI agents and auditors.

Use Cases

Designed for regulated industries.

Regulatory Compliance

Maintain verifiable evidence of KYC/AML activities, transaction monitoring, and regulatory reporting with cryptographic proof.

Audit Readiness

Pre-structured evidence packages ready for internal and external auditors. No more weeks of manual reconstruction.

Automated Compliance Reporting

AI agents analyze verifiable records and produce compliance reports backed by cryptographic proof via MCP.

Legal Evidence Preservation

Chronologically ordered records with qualified timestamps that support court-admissible evidentiary workflows.

Why VeriLedger

Not another logging tool.

VeriLedger is evidence infrastructure, not an append to your SIEM.

AI-Native

Built for the era of AI agents.

Modern compliance tools will increasingly rely on AI agents. VeriLedger provides structured, machine-readable evidence accessible through the Model Context Protocol.

1

Structured evidence records

Every record follows a consistent schema that AI agents can parse and reason about.

2

Context-aware queries via MCP

Agents query evidence using natural language through the Model Context Protocol server.

3

Automated reasoning over provable facts

AI agents can verify evidence integrity before generating compliance reports or making decisions.

Regulatory Alignment

Aligned with European regulatory evolution.

eIDAS2 and Qualified Electronic Ledgers

VeriLedger is designed to align with the evolution of European trust infrastructure. The eIDAS2 regulation introduces the concept of Qualified Electronic Ledgers — a new trust service category for distributed ledgers that meet specific security, governance, and interoperability requirements.

Our long-term vision is to support infrastructures capable of operating within the European trust services ecosystem, providing organizations with a credible path toward regulatory compliance as these standards mature.

eIDAS2 QTSP-ready RFC 3161 ETSI Standards

TRUST SERVICES

Qualified Electronic Ledgers

A new eIDAS2 trust service category for distributed ledgers that record data with a presumption of accuracy and integrity.

TIMESTAMPS

Qualified Timestamps

RFC 3161 integration with qualified TSA providers for legally binding time proof across the European Union.

COMPLIANCE

Future-Proof Architecture

Positioned ahead of regulatory requirements so organizations can adopt now and certify as standards are finalized.

Security

Security by design.

Immutable Ledger

Append-only architecture. No record can be modified or deleted after creation. Any tampering breaks the hash chain.

Cryptographic Integrity

SHA-256 hashing and Ed25519 digital signatures on every record ensure provable integrity and non-repudiation.

Qualified Timestamps

RFC 3161 TSA integration provides legal-grade time proof from independent qualified timestamp authorities.

Access Control

Role-based access control with a complete audit trail on every query and administrative action.

Data Residency

European hosting with configurable data residency policies. Full control over where evidence data is stored and processed.

Merkle Anchoring

Periodic Merkle root computation enables batch verification and external anchoring for independent audit proof.
