A joint effort to establish Blockchain Infrastructure and Personal Data Management for Health
When laying the foundation for a robust interoperable healthcare system we need to start at the protocol level and design new infrastructure that is owned and controlled by no one and everyone. We need identity and digital value protocol layers and immutable health records controlled by their rightful owners. This is the promise of Blockchain and the starting point for a reinvented healthcare system.


The promise and value of blockchain technology comes from how it can enable coordination of large scale collaboration in open ecosystems. However, in order to minimise coordination , initially, we propose the establishment of a national consortia within the Swedish ecosystem to tackle the regulatory challenges in a confined and local context first.

We are not developing the technology but rolling out the infrastructure to start testing and take advantage of the automation and security benefits to be reaped already today. The first and most important fix is to flip the data ownership model towards Self-Sovereign Health Records. We are ready to deploy this but for resiliance and to achieve security by numbers in our consensus algorithm we need members to run and guarantee network nodes.

The CareChain consortium was founded by CareChain AB in March 2017 and we are now actively soliciting co-founding partners.


What We Do


As far as possible, we intend to take advantage of the tools of the trade and automate most of the decision making using Smart Contracts.


We will continue to seek membership in relevant standardisation organisations to track these emerging technologies and interoperability protocols.


The founding partner, CareChain AB, manages the infrastructure. Members can choose to take advantage of the fully managed Blockchain-as-a-Service, or run self-hosted network nodes, including available laptop nodes.


This technology is applicable horisontally across all types of organisations.

Global Technology Consortia

We are members the Enterprise Ethereum Alliance and follow closely the use case work being done in the HyperLedger Healthcare Working Group.

The Team

We're a small team with significant experience in creating value through digitalization. We have lived and worked in Silicon Valley and have founded, co-founded or been part of the founding team of a number of startups. We're convinced that the digitalization of the healthcare sector offers enormous opportunities for improving the quality of life of individuals as well as benefiting the society at large.
