Detailed description

Metadium allows people to move from a restricted centralized method to a secure and transparent protocol that embraces limitless possibilities. Importantly, through Metadium, individuals have full ownership of their identity for the first time. Transferring ownership from central authorities to individuals not only protects their precious information from hackers and data leaks, but also allows people to select which information they wish to provide to service providers or other organisations.

With Metadium powered by blockchain, individuals finally have the power to manage, protect and use their personal data when and how they want, both domestically and globally.


  • Data can be sold to third-parties without your permission for advertising and marketing purposes
  • Centralized authorities have total control of your valuable personal information
  • Hacking attempts on services you use can lead to undesired leaks, including your personal data


Easily access any service with one integrated Meta ID:

  • All off-chain & inter-blockchain Services are supported
  • One Meta ID - no multiple ID/PWs

With Meta ID, have total control of your information:

  • Full control and use of your data
  • Use attested or self-sovereign
  • Provide all or partial data only with your consent

Your identity is safe and supported by Metadium:

  • Securely access, manage and use your personal data
  • DPKI powered by blockchain, protects you from leaks


Protocol baseline - trustless trust
Metadium is powered by blockchain using “trustless trust”. As a decentralized ledger, blockchain is regarded as “trustless”, meaning no central authority controls the process. Although the internet and online society have rapidly developed in a short-term period of time, identity on the internet has been relatively overlooked. Our PKI-driven identity ecosystem challenges the centralized status quo. Metadium fosters a virtuous identity ecosystem using protocol-baseline ideology to offer unquestionable, distributed trustworthy identity online, without the need for a central authority.

Decentralized PKI
Metadium decentralized PKI (dPKI) enables individuals to securely trust the integrity of the identity. Trustless trust means managing identities without wasting effort or money. Corporations and individuals have ownership over their personal data and control how, when and with whom they share data with.

Data ownership and self-sovereign identity
By implementing self-sovereign identity, each individual or user can convey preferences or correlations between several digital identities. For example, the digital identity of content creator A allows them to determine their correlation between the mundane identity and provide data without revealing private information like their gender or geographical location.

As blockchain supports pseudonymity and “trustlessness”, regulatory authorities have raised concerns with the adoption of such technology. In this regard, Metadium enables blockchains to be regulated without compromising the spirit of pseudonymity and trustlessness.

Identity of Things
Up until recently, identity infrastructure has been more focused on eligibility and purpose, rather than value or self-awareness. Of course, there are identity infrastructures dedicated to value-adding and preserving. Intellectual Property (IP) rights typically include elements of the Identity of Things (IoT), but IPs are more likely to be focused on the right to preserve financial or possessive value. With technological developments, implementing identity for IoT devices, logistics, robotics, AI and smart cities will increase the demand for accessing and sharing more information. Granting identity to devices and objects (things) will be spontaneously generalized.

Attestation and verification
Verification and attestation are totally different elements. While the verification process can basically be done via a more cognitive approach, attestation requires third-party notaries or another publicly-accredited intermediary. For example, to add extra value to pseudonymous identity, relationship identity and Identity of Things, verification suffices. However, for more crucial information requirements or when clarifying identify to prove rights or genuineness, attestation is needed.
