Ruan, a Des Moines-based transportation company, has joined the Blockchain in Transport Alliance (BiTA), the company announced Tuesday. BiTA claims to be the largest commercial blockchain alliance in the world, with nearly 500 members in more than 25 countries. Blockchain technology enables transactions to be identified and tracked digitally, and shared across a distributed network of computers. That technology can help supply and transportation companies effectively track freight and operate in a more seamless manner. Ruan’s six-person internal Blockchain Forum meets bi-weekly to educate the company on blockchain technology, and is working to deploy a prototype blockchain in 2019.
