There is a great article in Forbes by Roger Aitken about how IBM is moving the BlockChain beyond Cryptocurrencies:
A group of leading retailers and food companies including Nestlé, Walmart and Unilever have signaled their commitment to “strengthen consumer confidence” in the foods they purchase by announcing a major blockchain collaboration with IBM. The consortium will work with ‘Big Blue’ to identify the “most urgent areas” across the global food supply chain that could benefit from the blockchain. Many of the critical issues impacting food safety such as contamination, food-borne illness, waste and the economic burden of recalls rest though on a lack of access to information and traceability.
By using blockchain, when a problem arises, the potential is to quickly identify what the source of contamination is since one can see across the whole ecosystem and where all the potential points of contamination could be – using the data to pinpoint the source. As such it is “ideally suited” according to IBM to address these challenges because it establishes a trusted environment for all transactions.
