Data in Chains

Data in Chains is a Helsinki-based software development company specialising in delivering blockchain and P2P based solutions for today’s problems. The first of its kind in Finland, we are currently helping Streamr, a Swiss based pioneering blockchain company build a decentralised network for trading real-time data. Beyond product development, we also offer a range of consulting services for businesses that want to join the blockchain revolution.
