We are proud to be part of CREAM — ESA’s cutting-edge automated collision avoidance platform — ensuring the security, integrity, and trustworthiness of mission-critical space traffic data.

Over the past seven years, Guardtime has researched and adapted its technology for the space domain, tackling one of the most pressing challenges in modern space operations: enabling secure, verifiable, and tamper-proof data.

As space becomes more crowded, collaboration and trust between actors are essential. With blockchain-enhanced security, CREAM can connect operators, streamline coordination, and safeguard sensitive operational data — from manoeuvre plans to collision-avoidance communications.

A big thank you to ESA and our partners, including GMV, for driving innovation in space safety.

We are thrilled to provide our KSI blockchain technology for the supply chain traceability in project 🚀

In today’s rapidly changing food industry, end-to-end traceability is crucial for driving efficiency, safety, and consumer trust. We at Guardtime, in collaboration with the project partners, are at the forefront of developing innovative technologies that ensure the future of food is transparent and secure.

Here’s why it matters:
🍒Enhanced food safety and compliance: Traceability enables quick identification of contamination sources, reducing food-borne illness risks. In 2023, global food recall costs hit $10B annually—traceability can slash these figures by targeting specific batches rather than entire lines, cutting recall volumes and costs.
🍒Boosting consumer trust: Transparency builds loyalty—94% of consumers stick with transparent brands, and 73% are willing to pay more for products with clear origins. Traceability fosters this trust by providing insight into food quality and sourcing.
🍒Protecting the products with geographical indication: Food fraud rose by 1041% between 2020-2023. Traceability ensures product authenticity and integrity, reducing mislabeling and fraud risks. This is especially important in the case of products with geographical indications with yearly sales value of €75 billion in the EU.
🍒Ensuring data integrity: Innovative blockchain technologies, like Guardtime’s KSI blockchain, guarantee tamper-proof data, protecting the food supply chain from manipulation and ensuring transparency.

Investing in end-to-end traceability is essential for a sustainable and trusted food future. Let’s trace the path forward! Stay tuned!
