Licium Digital Rights Engine

Licium is a decentralised app for trusted digital content licensing
and a decentralised rights engine.

Licium allows rightsholders, content creators, media organisations
and other users:

  • to manage decentralised content identifiers for digital assets (ISCC)
  • register them on public ledgers
  • create non-fungible tokens (NFTs and smart contracts)
  • generate content certificates that verify authenticity of original content and rightsholder identity  
  • and inseparably associate metadata, licensing terms, rights management information and other claims with the content

– for a proper attribution and fair remuneration of creative work in increasingly networked and heterogeneous digital media environments

The Open Content Certification Protocol (OCCP)

The OCCP provides a description of the process and involved technologies that can be used by creative individuals, media organisations or consumers to generate or verify certificates for digital media content.

Content certificates allow rightsholders to inseparably and verifiably connect information, basic metadata, licensing terms and other rights management information to digital content.

It is the goal of the certification process to create trust in assertions, claims and the authenticity of the original content, and to ensure accountability of entities, even if they must or prefer to remain pseudonymous.

Decentralization and Scarcity — Blockchain and the Cultural Industries

In 2019 I wrote a post on the structural implications of blockchain technology and cryptocurrencies for the creative community in a truly decentralized media environment. It tries to give a brief outlook on the future of business models, services and applications for writers and artists as well as for other professionals within the cultural industries and institutions.

The post has been published by the Acción Cultural Española (AC/E) in the AC/E Digital Culture Yearbook 2019 in Spanish language on May 8, 2019. You can download the e-book for free.

ISCC - International Standard Content Code

Freely accessible standard identifiers, which are specifically designed to manage digital content, are a fundamental prerequisite for efficient transactions in a decentralized and increasingly heterogeneous media environment.

The ISCC (International Standard Content Code) is the first open, generic identifier designed for digital media content. It can be used to register content on the decentralized ledger and also in off-chain environments.

Content Blockchain Project

The Content Blockchain is an open initiative and decentralized blockchain network tailored to the specific needs of the digital media content ecosystem. The global network supports content related transactions and digital media licensing. It operates based on an open governance model and is owned by the participants themselves.

The initiative is providing the foundational tools and standards required for building innovative applications and services on the blockchain. These enable creative individuals, media companies and cultural institutions to better discover, access, manage, share, offer and license digital media content and exchange value through the network.

Content Blockchain nominated for the 'Blockchain for Social Good'-Prize

The Content Blockchain Initiative has been nominated as one of the 24 finalists of the ‘EIC Prize Blockchain for Social Good‘.

On the 30st of June 2020, the European Commission came to a descision: Congratulations to the winner teams! 

This is the transcript of our short presentation:

Content Blockchain Project honored with the 'digital publishing award' 2019

The Content Blockchain Project is the winner of the ‘digital publishing award’ 2019 in the category ‘startups’. The collaborative initiative has been awarded in recognition for its ambition to trigger digital innovation in the publishing industry by promoting a blockchain infrastructure dedicated to media content. The project also provides tools and standards with immediate utility for publishers that want to engage with decentralized ledger technology.

The ‘digital publishing award’ is hosted under the patronage of the German Federal Ministry of Economic Affairs and Energy. 

Content Identification on the Blockchain

The ISCC is defined as an open and decentralized digital media identifier, unambiguously identifying digital content. It is a unique, hierarchically structured composite identifier, that is generated algorithmically and in a decentralized way. It is built from a generic and balanced mix of content-derived, locality-sensitive and similarity-preserving hashes generated from metadata and content. This inseparably links any specific content to a specific ISCC identifier. Read more …

What is a Smart License?

Smart Licenses are legal representations that will allow rights owners a simple means to offer and trade content globally in a secure and reliable, open and transparent, automated and machine-readable way on the Content Blockchain. Read more …

International Digital Distribution

Changes in publishing and distribution technologies offer publishers and authors worldwide the opportunity to break out of their geographic region and to sell books print-on-demand and in e-book formats and sell to readers in the European and global markets—without licensing, directly, at a reasonable cost.

Through my broad international network of marketing experts I am happy to support local publishers marketing books worldwide, which are not licensed in the traditional way, and connect publishers to readers in the various global markets.


Occasionally, I blog about digital media and publishing in the 21st century, the time of digital transition. The posts on this blog are intended to accompany digital change in the media industry, providing background knowledge and specialist information as well as analyses of digital topics.
