What is Sigalmark?

Sigalmark is a digital verification ecosystem built on secure blockchain technology. It enables organisations to issue, manage, & utilise authentic, verifiable credentials efficiently, & accessibly in real time.

Each Sigalmark is an NFT-backed QR code acting as a digital twin of a credential capturing origin, issuer, and current status.

How Sigalmark Works

Sigalmark connects issuers, holders, and verifiers through a simple, secure, and transparent platform.

Issuer Control Platform

Accredited organisations such as membership bodies, certification authorities, or educational institutions access the Sigalmark SaaS dashboard to issue or revoke validation events in real-time, with complete administrative control and blockchain-backed audit readiness.

NFT-Backed Verification

Each accreditation, membership, or certificate is encoded as a two-layered NFT, creating a secure, unique and verifiable chain of custody tied to a QR code that can be embedded digitally or physically via ID cards and printed certificates.

Instant Validation

When scanned, the NFT links directly to the Sigalmark verification portal, instantly confirming whether the holder's status is valid, expired, or revoked. Anyone — consumers, hiring managers, or regulators — can trust what they see.

Lifecycle Management

Credentials are managed throughout their full lifecycle — from issuance to renewal to revocation. Status changes propagate instantly, ensuring every Sigalmark always reflects the most current, accurate information.

The Four Core Pillars of Sigalmark

While Digital Product Passports focus on materials and lifecycle traceability, Sigalmark adapts these principles to the integrity of accreditations, certifications, and membership verification.

Consumer & Stakeholder Trust

Sigalmark empowers end-users to instantly verify the legitimacy and currency of a credential. One scan reveals who issued it, when it was last validated, and whether it is still active — reinforcing trust in the issuing organisation.

Sustainability & Digital Efficiency

By digitising certificates, logos, and membership marks, Sigalmark eliminates paper-based documentation, reduces administrative overhead, and minimises fraud vectors — supporting a sustainable digital-first approach to accreditation.

Traceability & Compliance

Every Sigalmark is blockchain-anchored, providing an immutable audit trail of where, when, and by whom a credential was issued or revoked — supporting regulatory adherence and full traceability.
