Along with Internet of Things -IoT-, distributed ledger/blockchain technology can provide substantial benefits to the management of supply chains. However the adoption of blockchain-based solutions may face substantial challenges such as scalability, which happens when several parties have to access and record information in a single blockchain. The use of two or more blockchains may help to mitigate such problem but it may require the use of an alternative architecture that enables interoperability. This work investigates the feasibility of adopting an agnostic blockchain architecture based on the particularities of the supply chain commonly found in the fisheries sector. A case in the fisheries sector in Atlantic Canada, characterized for the capture of different species destined for markets worldwide, is used to explore the adoption of an agnostic blockchain architecture. Emerging concepts such as agnotic blockchain applied to the supply chains of perishable goods may open the door to the development of innovative solutions.
