BlockScience, founded in 2017, is an R&D, engineering, and analytics firm that specializes in the design and analysis of complex systems. With an interdisciplinary team of engineers, data scientists, and social scientists, the company applies advanced mathematical and computational engineering to model, simulate, and design resilient socio-technical systems for a diverse range of clients, including for-profit companies, non-profits, and government organizations.
The firm's core service is providing a rigorous, data-driven approach to designing and validating economic and governance mechanisms. A key product in their toolkit is cadCAD, an open-source Python-based modeling framework they developed. This tool allows for the creation of "digital twins" of complex systems, enabling clients to simulate and test new business models, market designs, or automated smart contract logic before deployment. This approach is used to analyse system safety, resilience, and sustainability under various conditions.
BlockScience has a direct collaboration with Hedera and the Hedera Foundation to design and model innovative market mechanisms for renewable energy and other environmental assets. This work includes the development of Automated Regression Market Makers (ARMMs), a novel price discovery mechanism for semi-fungible assets like energy credits.

Atma.io, a venture by Avery Dennison, is a connected product cloud platform designed to bridge the physical and digital asset worlds by assigning unique digital identities to everyday items. The Atma platform enables end-to-end supply chain transparency via the Hedera blockchain, allowing businesses and consumers to track products from source to point of sale and beyond. It accomplishes this through the use of identification technologies such as RFID and QR codes to capture and manage vast amounts of data about individual product journeys.
A crucial component of Atma.io's architecture is its use of the Hedera Hashgraph distributed ledger technology (DLT) to ensure the immutability and verifiability of supply chain events and sustainability credentials. This provides a trusted layer for product authentication and helps combat counterfeiting.
Serving a multitude of industries, including apparel, retail, food and beverage, and pharmaceuticals, Atma.io offers solutions for enhanced inventory management, improved operational efficiency, and deeper consumer engagement. It can be utilized to share verifiable product origin stories, provide detailed sustainability information, and support circular economy initiatives.
